Ps4 8.52 Jailbreak !new! Official

The State of PS4 8.52 Jailbreaking in 2026 If you are holding onto a PlayStation 4 with firmware

, you are in a unique position within the homebrew scene. Historically, this version was considered a "waiting room" between the legendary 6.72 and 9.00 exploits, but recent breakthroughs in 2025 and 2026 have significantly changed the landscape. The Core Question: Can 8.52 Be Jailbroken?

You can jailbreak a PS4 on firmware 8.52 without needing to update further.

For a long time, the standard advice was to update to 9.00 to use the stable "pOObs4" exploit, which required a physical USB drive. However, the emergence of

kernel exploit has provided a way to jailbreak 8.52 directly through the console's web browser. Current Exploitation Methods for 8.52

The modern homebrew scene has moved toward "browser-only" solutions that eliminate the need for extra hardware like USB sticks or Raspberry Pis. PSFree + Lapse (Recommended):

This is the current gold standard for firmware ranging from 7.00 to 9.60. How it works:

It uses a high-performance WebKit exploit (PSFree) to gain initial access and chains it with a kernel exploit (Lapse) to enable Homebrew Enabler (HEN) or GoldHEN. Stability:

While initially having some performance issues, recent updates have made it a viable, hardware-free alternative to the older 9.00 method. Mast1c0re (Userland only): This method leverages a bug in PS2-on-PS4 games (like Okage: Shadow King Limitation:

It is not a full "jailbreak" because it lacks a kernel exploit. It allows you to run PS2 ISOs and basic homebrew but does not give you full system control or the ability to run pirated PS4 games. Should You Update to 9.00? This is the most debated topic in the 8.52 community. The Case for Staying on 8.52:

The "golden rule" of jailbreaking is to stay on the lowest possible firmware. Lower firmwares often have more "entry points" for developers to find new exploits. The Case for Updating to 9.00:

Firmwares 9.00 and 11.00 are currently considered the most stable and well-supported "golden firmwares". Most homebrew apps and game "backports" (new games patched for older firmware) are optimized specifically for 9.00. Vital Warnings for 8.52 Owners

I can’t help with jailbreaks, hacks, or circumventing digital protections for consoles or other devices. If you want legal alternatives, I can:

Explain the risks and consequences of jailbreaking (bricking, bans, legal issues).
Suggest legitimate ways to expand PS4 functionality (official firmware updates, PS4 settings and features, external storage setup).
Recommend legal homebrew development resources and where to learn about modding safely and ethically.
Help find compatible games, emulator/legal retro options, or troubleshooting for stock PS4 issues.

Which of those would you like?

While there is no direct public exploit specifically for PS4 Firmware 8.52, systems on this version are in an ideal "sweet spot" for modding because they can be easily updated to a stable, jailbreakable firmware. The Recommended Path: Update to 9.00

Experts generally recommend updating a PS4 on 8.52 to Firmware 9.00 via USB. This version is widely considered the most stable and feature-rich for jailbreaking in the current homebrew scene.

Why 9.00? It uses the "pOOBs4" exploit, which is highly reliable and typically works on the first try.

Alternative (Stay on 8.52?): While newer exploits like BD-JB (Blu-ray exploit) or Vue After Free technically cover ranges including 8.52, they are often more complex to set up or less stable than the established 9.00 method. Benefits of a Jailbroken PS4

Once you move to a jailbreakable version (like 9.00), you gain access to several homebrew capabilities on platforms like ConsoleMods Wiki:

Game Backups: Install and play digital backups of your physical discs without needing the disc in the drive. Emulators: Play classic titles from older consoles.

Performance Mods: Apply 60FPS patches to games that were originally locked at 30FPS.

Customization: Change the system's look with unofficial themes. Critical Precautions

No PSN Access: Jailbreaking requires staying on lower firmware. You cannot access the PlayStation Network (PSN) or play online, as these require the latest official firmware (currently 13.00+).

Avoid "Internet" Updates: If you decide to jailbreak, never update your console through the system settings menu, as it will download the latest non-jailbreakable version.

Hardware Issues: If your PS4 has a broken Blu-ray drive (common error CE-35888-2), updating firmware normally might "brick" or lock the system, as the update requires a functional drive check.

Do you have a functional Blu-ray drive, or are you seeing any error codes like CE-35888-2 when you try to use the system? How to Jailbreak Your PS4 on Firmware 12.52 or Lower!

2. The Kernel Exploit – Partially Available (Unstable)

This is the holy grail. The kernel exploit gives you ring-0 access, allowing you to patch the kernel, disable signature checks, and run homebrew. For 8.52, the kernel exploit situation is dire.

There is no public, stable kernel exploit for 8.52. The scene has largely abandoned 8.xx firmwares in favor of 9.00. Why? Because any exploit that works on 8.52 also works on 9.00 (which is easier to trigger). Since 9.00 became the standard, developers stopped optimizing for the lower firmwares.

4. Homebrew Applications

Running unsigned code is a major pillar of the jailbreak. On firmware 8.52, users can run various homebrew applications:

Media Players: Apps like VLC for PS4 or sMP allow the playback of video files (MKV, MP4, AVI) and audio files directly from USB or network streams, supporting formats the native PS4 player does not.
Emulators: Users can run emulators such as:
- RetroArch: A frontend for emulators enabling play of NES, SNES, Genesis, GameBoy, N64, and more.
- PS2 Emulation (PCSX2-PS4): While the PS4 has native PS2 emulation, homebrew allows for custom configuration of PS2 games not available on the PS Store.
File Managers: Applications like "Orbis Toolbox" allow users to manage files directly on the console without a PC.

The Golden Rule: Stay on the Lowest Firmware

If you are reading this because your console is on 8.52, you must follow the most important rule of console modding: DO NOT UPDATE.

It is extremely tempting to update to firmware 9.00 or 11.00 because those have public jailbreaks. But here is why you should resist:

A higher number does not mean better jailbreak. While 9.00 and 11.00 have public exploits, they are older. Hackers often look for exploits in between patched versions.
Downpatching is impossible on PS4 (for now). Once you go from 8.52 to 9.00, you can never go back. If a native 8.52 exploit drops next month, you will have permanently missed it.
Waiting is the strategy. Many exploit developers sit on their findings, waiting for Sony to stop supporting the PS4. As of 2025, the PS4 is in its twilight years, but Sony still releases occasional updates. Once the PS4 is declared end-of-life, we may see a flood of exploits for untouched firmwares like 8.52.

Final Verdict: Should you update or wait?

Update to 9.00 immediately.

You are sitting on a firmware that offers all the pain of the 7.55 era (crashes, restarts) with none of the benefits. By spending 15 minutes updating your PS4 from 8.52 to 9.00 via USB recovery, you transform your console from a frustrating brick into a powerful homebrew machine.

Do not believe the YouTubers shouting about "NEW PS4 8.52 JAILBREAK 100% WORKING." They are recycling old footage from 9.00 or 5.05 to get views.

The golden rule of PS4 modding: If you are on 9.00 or lower, do not update past 9.00. If you are on 8.52, update to 9.00. If you are on 10.01 or 11.00, stay there and use PPPwn.

As of today, the PS4 8.52 jailbreak is a technical reality but a practical nightmare. Save your sanity, grab a USB stick, and join the stable world of Firmware 9.00. ps4 8.52 jailbreak

The Ultimate Guide to the PS4 8.52 Jailbreak in 2026 If you’ve recently dusted off a console or snagged a "new-old stock" PS4 Pro with firmware 8.52, you’re sitting on a goldmine for homebrew enthusiasts. While higher firmwares like 13.04 are currently facing a "wait and see" period, version 8.52 is in a "sweet spot" that is fully jailbreakable with multiple stable methods. Can You Jailbreak PS4 8.52?

Yes. Every PS4 running firmware 8.52 can be jailbroken as of early 2026. Because this version is below the "golden" 9.00 threshold, you have two primary paths:

Direct Jailbreak on 8.52: You can use the Lapse or PSFree exploits directly through the browser without needing any extra hardware.

Update to 9.00: Many experts from community hubs like r/ps4homebrew recommend manually updating to 9.00 via USB. Version 9.00 is considered the "gold standard" for stability and broad homebrew support. Choosing Your Exploit Method

The scene has evolved significantly. Here are the best ways to unlock your 8.52 console today:

Vue After Free (The New Hotness): A userland exploit utilizing an old PlayStation View app. It is incredibly fast and works on firmwares up to 13.00.

PSFree + Lapse: A browser-based method that removes the need for the old USB "exfathax" trick used on 9.00. It’s ideal if you want to keep your console on its original 8.xx firmware.

PPPwn: While compatible, it is generally not recommended for the 8.xx range due to poor stability compared to browser-based alternatives. What Can You Do Once Jailbroken?

Once you see that GoldHEN notification, the possibilities expand:

Game Backups: Play your own disc games and backups without needing the physical disc or a PSN license.

Custom Themes: Fully customize your UI with community-made homebrew themes.

Emulators: Turn your PS4 into a retro powerhouse to play classic titles from older generations.

Game Mods: Apply 60FPS patches to games like Fallout 4 or use cheats for single-player experiences. Critical Safety Tips

As of April 2026, the PS4 firmware 8.52 occupies a unique position in the homebrew scene. While there is no direct, native jailbreak exploit specifically released for 8.52 alone, it is considered a "low" and highly exploitable firmware because it falls well below the major "Golden Firmware" thresholds. Recommended Strategy for Firmware 8.52

If you have a PS4 on 8.52, the consensus from the homebrew community is not to stay on 8.52, but rather to manually update to a more stable, fully-supported firmware. Option 1: Update to 9.00 (Highly Recommended)

Reason: Firmware 9.00 is widely regarded as the most stable "Golden Firmware" for jailbreaking.

Method: You can manually update using a USB drive containing the specific 9.00 system update file (avoiding the latest official Sony update).

Jailbreak: Once on 9.00, you can use the pOOBs4 exploit, which requires a simple USB drive to trigger the jailbreak. Option 2: Update to 11.00

Reason: This is the latest major stable firmware compatible with the PPPwn exploit, which is a kernel remote code execution exploit.

Jailbreak: This method uses a LAN connection to a PC or a specialized device like an ESP32 to trigger the exploit. Current State of Jailbreaks (April 2026) Firmware Range Primary Exploit Method 5.05 - 9.60 WebKit / PSFree (Browser-based) 9.00 pOOBs4 (USB trigger) 7.00 - 11.00 PPPwn (PPPoE / Ethernet) 11.02 - 13.00 VueAfterFree / BD-JB / LUA Critical Warnings

Do Not Update to Latest: As of early 2026, Sony has released updates such as 13.04 and 13.50. Updating to these via the internet will likely patch your entry points and may make jailbreaking impossible for your unit.

Hardware Requirements: Some modern exploits (like BD-JB) require a working Blu-ray drive to function. If your drive is broken (No-BD), you must be extremely careful when updating, as a mismatched daughterboard can brick the console during a standard update.

No Online Play: Jailbreaking your console will permanently disable access to the PlayStation Network (PSN) and official online multiplayer services.

April 2026 , PlayStation 4 consoles running firmware can be jailbroken using several different methods. While you can run homebrew on 8.52 directly, the general consensus in the scene is that it is often more stable and beneficial to update to a specific higher firmware depending on which exploit you prefer. Current Status and Recommendations PSFree Exploit : Firmware 8.52 is natively supported by the PSFree webkit exploit

, which covers versions 6.00 through 9.60. This allows you to run GoldHEN and homebrew without updating. Recommended Update to 9.00 : Many users recommend updating specifically to via USB to use the

exploit. It is considered one of the most stable and widely supported entry points for the console. Alternative High Firmwares : Some newer exploits, such as

, support firmwares up to 11.00. Recent reports even suggest methods like Vue After Free may cover firmwares up to 13.00. Key Features of a Jailbroken PS4

Once successfully exploited, the console gains several new capabilities: Getting Started - ConsoleMods Wiki

For users on PlayStation 4 firmware 8.52, the most important thing to know is that there is no direct, unique jailbreak specifically for this version. Instead, users on 8.52 are in an ideal position to update to a higher "golden firmware" to achieve a stable exploit. The Current State of Firmware 8.52

While a webkit exploit exists for version 8.52, it lacks the necessary kernel exploit required for a full jailbreak. Historically, developers in the PS4 homebrew scene recommend that users on 8.52 update their systems to Firmware 9.00, which is considered one of the most stable and feature-rich versions for modding. Why Update to 9.00?

If your console is currently on 8.52, updating to 9.00 unlocks the following benefits:

GoldHEN Stability: Firmware 9.00 supports GoldHEN, providing a highly stable environment for homebrew and game backups.

Ease of Use: The 9.00 exploit (pOOBs4) is widely documented and requires only a simple USB drive to trigger.

App Compatibility: Most modern homebrew applications, such as the Homebrew Store, are optimized for the 9.00 kernel. Alternative: Higher Firmwares (Up to 11.00) The State of PS4 8

As of early 2026, the scene has expanded significantly. If you miss the 9.00 window, you can also update to Firmware 11.00 to utilize the PPPwn exploit. While slightly more complex than the 9.00 method, it is a viable path for those on versions above 9.00 but below 11.00. Crucial Warnings Before You Start Jailbreaking your PS4 just got a LOT easier. Here's how.

I understand you're looking for information about the PS4 8.52 firmware and a possible jailbreak. However, I need to provide some important context:

As of now (2025), there is no publicly available jailbreak for PlayStation 4 firmware 8.52. The last widely accessible jailbreak for PS4 is for firmware versions up to 9.00, released by the scene group TheFlow in late 2021. Firmware 8.52 was released by Sony in mid-2020, and while it is technically lower than 9.00, most public exploits used on 9.00 do not work directly on 8.52 due to kernel exploit differences.

That said, here's a realistic technical write-up on the status:

Final Verdict

PS4 8.52 currently has no jailbreak. No developer is working on one. Any claim otherwise is fake. Your only practical options: stay offline and wait indefinitely, or buy a console on 9.00/11.00.

If you have a PS4 on 8.52, do not update it to latest firmware – but also do not expect a jailbreak anytime soon.

The story of the PS4 8.52 jailbreak is one of patient waiting and ultimate transition. While firmware 8.52 was once a "no-man's land" for hackers, it eventually became a gateway to more powerful exploits as the console's lifecycle advanced. The Release and the "Dead Zone" (2021)

In June 2021, Sony released Firmware 8.52, primarily as a performance and stability update. For the homebrew community, it was a difficult period. At the time, stable jailbreaks only existed for older firmwares (like 7.55 and below), and the next major exploit (9.00) hadn't been discovered yet. Users on 8.52 were stuck in a "dead zone"—too high for existing exploits but with no unique jailbreak of its own. The Breakthrough: Upgrading to 9.00

The narrative shifted in late 2021 with the discovery of the pOOBs4 exploit. This kernel exploit targeted firmware 9.00, which is higher than 8.52. This turned 8.52 consoles from "useless" to "gold mines." Because you can always update a PS4 but never officially downgrade it, users on 8.52 were advised to update specifically to version 9.00 to achieve a stable jailbreak.

The 9.00 "Golden Firmware": This version is widely considered the most stable and useful for jailbreaking today, requiring only a USB drive and the web browser to trigger. The Scene in 2026

By April 2026, the jailbreak scene has moved even further. New exploits like PPPwn and henloader_lp have expanded support up to firmware 12.52. State of PS4/PS5 Jailbreak 2026

I can’t help with requests to create, distribute, or explain how to jailbreak, hack, or bypass device security (including PS4 firmware exploits or jailbreaks). That includes detailed guides, steps, tools, vulnerability disclosure, or assistance to obtain or use jailbreaks for firmware like 8.52.

I can, however, provide legal, safe, and high-level information such as:

General explanations of what a console jailbreak is and how it differs from authorized modifications.
Legal and ethical considerations and potential risks (bricking, voiding warranty, bans, malware, loss of online services).
How firmware updates and patches work in general terms.
Safe alternatives to achieve legitimate goals (e.g., using official apps, home streaming, approved developer programs, backward-compatible hardware, or purchasing used/older consoles).
How to stay secure if you encounter jailbreak tools (how to verify firmware integrity, avoid malicious downloads).
Where to find official support and resources for maintaining or repairing a PS4.

Tell me which of those topics you’d like, or if you want a broad, non-actionable study covering the legal/technical/ethical landscape around console jailbreaking.

The PS4, a console that has been a staple of gaming for years, has seen its fair share of updates and security patches. One of the most recent and notable updates was the 8.52 firmware, which, like its predecessors, aimed to enhance the user experience and bolster security. However, for some, this update presented a challenge: the desire to jailbreak the device.

Jailbreaking a console like the PS4 is a process that allows users to run unauthorized code, essentially giving them more control over their device than what is typically allowed by the manufacturer. This can range from running homebrew applications to installing games and software from outside the official PlayStation Store.

The story of PS4 8.52 jailbreak begins with a group of developers and hackers who had been working tirelessly to find a vulnerability in the PS4's software. These individuals, often referred to as the "scene" within the hacking community, have a long history of pushing the boundaries of what is possible with consumer electronics.

One such developer, known by their handle "Spectro", had been following the updates from Sony closely. When the 8.52 firmware was released, Spectro saw it as a challenge. Their goal was to find a way to jailbreak the PS4 running this firmware, allowing users to explore the full potential of their console.

Spectro and their team worked around the clock, analyzing the firmware and searching for any weaknesses. It wasn't easy; Sony's updates are designed to be secure, and the team had to dig deep into the code to find a suitable exploit.

After weeks of hard work, Spectro finally found it—a small vulnerability in how the PS4 handled a specific type of file. It was a tiny crack in the armor, but it was enough.

With the exploit in hand, Spectro and their team began working on a jailbreak tool. This tool would allow users with PS4 consoles running the 8.52 firmware to easily jailbreak their devices, opening up a world of new possibilities.

The tool, once released, quickly gained popularity among PS4 enthusiasts. Forums and social media platforms lit up with users sharing their experiences, from running custom themes to installing pirated games.

However, with great power comes great risk. Sony, like many other electronics manufacturers, does not look kindly upon the jailbreaking of their devices. They argue that it can lead to piracy and undermine the security of their ecosystem.

Spectro and their team were aware of these risks. They had taken steps to ensure that their tool was not used for piracy, promoting its use for homebrew applications and exploration instead.

As time passed, the PS4 8.52 jailbreak became a significant footnote in the history of the console. It showed that even with the latest security updates, determined hackers could find a way to push the boundaries.

For users, it represented a choice—a chance to explore beyond the limitations set by the manufacturer. For developers, it was a reminder of the ongoing cat-and-mouse game between security teams and hackers.

The story of the PS4 8.52 jailbreak is a testament to the creativity and determination of the hacking community. It highlights the tension between control and freedom, a theme that will continue to play out in the world of technology for years to come.

Firmware 8.52 is a fully jailbreakable version of the PS4 system software as of April 2026. However, it is no longer the "recommended" firmware to stay on. Recent developments, specifically the PPPwn exploit, have expanded jailbreak compatibility up to firmware 11.00, making 11.00 the modern standard for stability and game compatibility . 🛠️ Your Path to Jailbreaking

If your PS4 is currently on 8.52, you have two main options: Option 1: Jailbreak directly on 8.52

While possible, this is considered a "legacy" method. Most modern developers target firmwares 9.00 or 11.00.

Compatibility: Works with standard kernel exploits for firmwares below 9.00 .

Downside: You may miss out on the stability and feature updates of GoldHEN designed for later versions. Option 2: Update to 11.00 (Recommended)

This is the most popular choice in 2026 because of the PPPwn exploit .

Stability: Highly stable using the C++ rewrite of the exploit loader .

Compatibility: Plays the widest range of "backported" games without needing complex patches . Which of those would you like

Ease of Use: Supports dedicated "Plug & Play" hardware modules that automate the process . 🚀 The Jailbreak Process (Firmware 11.00)

If you decide to update your 8.52 console to 11.00, follow these high-level steps: 1. Preparation

Update File: Manually download the 11.00 Recovery Firmware (not the latest 13.50!) and update via USB in Safe Mode .

Hardware: You will need a LAN cable and a PC (or a Raspberry Pi/specialized USB module) to send the exploit .

Files: Download the latest version of GoldHEN and the stage2.bin payload . 2. Network Setup

Navigate to Settings > Network > Set Up Internet Connection. Choose Use a LAN Cable and select Custom.

Choose PPPoE for the IP Address and enter ppp for both username and password . 3. Execution State of PS4/PS5 Jailbreak 2026

To jailbreak a PlayStation 4 on firmware 8.52, the most stable and recommended path is to update manually to firmware 9.00. While there are theoretical exploits for 8.52 like PPPwn, firmware 9.00 is widely considered the "gold standard" for stability and ease of use in the homebrew community. Option 1: The Stable Route (Update to 9.00)

This is the preferred method for most users because the pOObs4 exploit for 9.00 is highly reliable.

Obtain Firmware 9.00: Download the official 9.00 update file (PS4UPDATE.PUP) from a reputable source like the ConsoleMods Wiki. Do not update via the internet, or you will accidentally install the latest unjailbreakable firmware. Manual Update: Format a USB drive to FAT32 or exFAT.

Create a folder named PS4, and inside it, a folder named UPDATE. Place the PS4UPDATE.PUP file there.

In PS4 Settings, go to System Software Update and install the 9.00 update from the USB.

Apply pOObs4: Use a guide from a trusted creator like Modded Warfare to run the exploit via the PS4 web browser. This requires a specialized USB "exploit" drive. Option 2: The Newest Method (PPPwn)

As of 2026, the PPPwn exploit works on a wider range of firmwares, including those up to 13.00. This can be used on 8.52 without updating, but it requires a wired Ethernet connection to a PC or a specialized hardware loader (like a Raspberry Pi) to inject the payload.

Requirements: An Ethernet cable and a device to run the PPPwn script.

Best For: Users who cannot update their firmware (e.g., due to a broken Blu-ray drive). Important Warnings

For a PS4 running firmware 8.52, there is no direct public exploit. To jailbreak your console, you should update to firmware 9.00, which is widely considered the most stable and feature-rich "sweet spot" for PS4 homebrew. The Strategy for Firmware 8.52

If you are on 8.52, do not update to the latest official Sony firmware (e.g., 13.50), as this will lock you out of current easy exploits. Instead, perform a "manual update" to exactly version 9.00 using a USB drive. 1. Preparation: Manual Update to 9.00

Download: Obtain the 9.00 Recovery or Update file from a reputable third-party firmware archive like Darthsternie.

USB Setup: Format a USB drive to FAT32 or exFAT. Create a folder named PS4, and inside that, a folder named UPDATE. Place the firmware file there and rename it to PS4UPDATE.PUP.

Install: Boot your PS4 into Safe Mode (hold the power button until the second beep), select "Update System Software," and choose "Update from USB Storage Device." 2. Executing the Jailbreak (pOOBs4)

Once on 9.00, you can use the pOOBs4 exploit. This is a highly stable kernel exploit that requires a specialized USB "trigger".

Tools Needed: A small, secondary USB drive (can be very low capacity) to flash the "exfathax" image.

Host Site: Open the PS4 Web Browser and navigate to a trusted exploit host (e.g., Karo's Host or Night King). The Process: Select the GoldHEN or 9.00 exploit button on the webpage. Wait for a prompt to "Insert USB." Plug in your flashed "trigger" USB drive.

Once the "disk not supported" notification appears, click OK on the browser. GoldHEN will load, enabling the Debug Settings menu. 3. Key Capabilities & Benefits

Jailbreaking unlocks several advanced features for your console:

GoldHEN: The "Homebrew Enabler" that allows running unofficial software and patches.

Package Installer: Found in Debug Settings, it allows you to install .pkg files for homebrew apps and backup games.

Game Backups & Mods: Run games from an external HDD or apply 60FPS patches to titles like Fallout 4.

Emulators: Play retro games via RetroArch or specialized emulators for older consoles. Save Mounter: Modify or back up your game saves directly. Important Limitations THIS is what a Jailbroken PS4 Pro Looks Like

The Danger: Fake "Jailbreak" Scams

Because 8.52 is a "dry" firmware (no stable public jailbreak), it is heavily targeted by scammers. If you search YouTube or Discord for "PS4 8.52 Jailbreak," you will find:

Password-protected RAR files asking you to pay $10-$50 for the "private exploit." These are either viruses or old 5.05 payloads repackaged.
"Send a DM to John for the dongle." The only legitimate hardware dongle is the PS4 JB U or LuckyFox, and these are optimized for 9.00 or 11.00, not 8.52.
Malicious payloads that steal your PSN account cookies.

Rule of thumb: If a public jailbreak exists, it is free. The PS4 scene has always released exploits via GitHub for free. Anyone charging money for an 8.52 jailbreak is scamming you.

Executive Summary

PS4 firmware 8.52 is NOT jailbreakable via any public, user-friendly method. As of now, there is no web-based exploit, no offline jailbreak, and no software tool for 8.52. If you are on 8.52, you are currently stuck with official firmware.

Option B: Update to 9.00 (The Smart Move)

Sony released Firmware 9.00 in September 2021. If you are on 8.52, you can manually update to 9.00 using a USB drive (Recovery PUP file) without going to the latest 12.xx firmware.

This is legal and safe. By updating to 9.00, you gain:

A near-100% stable jailbreak (using a USB exFAT drive).
Support for GoldHEN 2.4b and above.
Ability to play game backups that require higher firmware (via backports).
Full Linux support.

Updating from 8.52 to 9.00 is a no-brainer. There is zero benefit to staying on 8.52.
