5. Conclusion

Score: 9/10

The iPhone 7 on iOS 15.7.3 represents a "Golden Era" for legacy modding. It combines the stability of mature software (iOS 15) with the power of an unpatchable hardware exploit (checkm8).

The killer feature is the native 32-bit architecture support. If you want a device that runs legacy apps, emulators, and system tweaks without needing a computer to re-jailbreak every time you reboot, this is the best device and firmware combination currently available.

Recommendation: If you have an iPhone 7 on this firmware, do not update. Preserve this setup. It is a highly capable machine that runs fast, jailbreaks smoothly, and offers functionality that modern iPhones simply cannot replicate.

Jailbreaking an iOS 15.7.3 is possible because of the bootrom exploit, which affects the A10 chip hardware. The most reliable and widely recommended tool for this specific configuration is Recommended Tools palera1n (Linux/macOS):

The primary tool for iOS 15-16 jailbreaking on checkm8 devices. It offers both "rootless" (modern, better compatibility) and "rootful" (legacy support) modes. palen1x (Windows): Since palera1n doesn't run directly on Windows,

is a bootable USB environment that allows you to run the jailbreak tool on a PC. Dopamine / NekoJB:

Newer semi-untethered options that may support some iOS 15 versions, though palera1n remains the standard for hardware-level exploits on iPhone 7. Preparation Checklist

6. Limitations and Drawbacks for 15.7.3 Users

Despite success, jailbreaking the iPhone 7 on 15.7.3 carries significant compromises:

| Limitation | Description | |------------|-------------| | Semi-Untethered | After every reboot, re-run palera1n from a computer to regain tweaks. | | No Passcode/Touch ID | You must disable the passcode permanently. Enabling it risks a boot loop. | | Rootless Tweaks Only | Most legacy tweaks (pre-iOS 15) are incompatible. Must use rootless versions from ellekit or roothide. | | Apple Pay Broken | SEP conflicts break Apple Pay and some NFC functions. | | No Windows Support | Palera1n requires macOS or Linux (Ubuntu live USB works). | | Potential Boot Loops | Installing incompatible tweaks (e.g., old SnowBoard versions) can force a DFU restore to 15.8.3 (the only signed version as of 2026). |

Top 5 Tweaks Working on iOS 15.7.3 (2026)
