While rooting a Go to product viewer dialog for this item. typically involves a computer to unlock the bootloader and flash files, a "no-PC" method can be achieved by using a second Android device to act as the terminal for flashing the patched boot image. Rooting Guide: The No-PC "Patched" Method
This process involves patching the device's boot image with Magisk and then using another phone to flash it via an OTG connection. Prerequisites
Unlocked Bootloader: This is the most critical step. Xiaomi requires the Mi Unlock Tool, which normally needs a PC. Attempting to root without an unlocked bootloader will fail. Second Android Device : To send fastboot commands. OTG Adapter: To connect the two phones.
Stock Firmware: Download the exact ROM version currently on your phone to extract the boot.img. 1. Patch the Boot Image

Connect the Phones: Use the OTG adapter and a USB cable to connect the two devices. 3. Flash via Fastboot
I understand you're looking to root a Redmi 9A without using a PC, specifically using a "patched" method (likely meaning a patched boot image or Magisk). However, I must inform you that rooting without a PC is extremely risky and unreliable for this model, and most one-click apps (like KingoRoot, iRoot) are either outdated, malware, or don't work on Android 10+ for Xiaomi devices.

That said, here is the closest possible method without a PC — but it still requires an unlocked bootloader, which normally needs a PC and Xiaomi's official unlock tool.
.zipMagisk-v26.1.apk → Magisk-v26.1.zip using any file managerOpen Terminal Emulator and type:
su
dd if=/sdcard/magisk_patched.img of=/dev/block/by-name/boot
reboot
(Note: The file name magisk_patched.img may vary. Check your internal storage.)
Your phone will reboot. If you see a black screen for more than 5 minutes, the patched image was incompatible – proceed to the troubleshooting section.
The term "patched" refers to modified APK files (applications) that bypass Xiaomi’s built-in security checks. Typically, apps like Magisk require a patched boot image flashed via Fastboot. The "patched method" we discuss here uses a combination of: Step 2: Rename APK to
| Pros | Cons | | :--- | :--- | | No need for a Windows/Mac PC | Requires bootloader unlock (still needs PC for initial Mi unlock) | | Good for on-the-go patching | High risk of bootloop if version mismatch | | Learn advanced Android internals | TWRP method unreliable on newer MIUI | | Saves time after bootloader is unlocked | No "easy button" — requires terminal commands |
If your goal is truly to root a Redmi 9A, the standard, safe process still involves a PC:
✅ This method works reliably and is malware-free.
❌ No PC-free alternative exists that is both safe and effective.
Even without a PC, you still need to unlock the bootloader (or at least trick it).
