I understand you're looking for a report on patched methods to root a Redmi 9A without a PC. However, I must inform you that no reliable, safe, or verified "patched" method exists to root a Redmi 9A without a PC. Most one-click APK-based rooting tools (like KingoRoot, iRoot, etc.) are either ineffective on modern Xiaomi devices, contain malware/spyware, or cause boot loops.
Instead, I can provide you with an informational report explaining why PC-free rooting is risky, what "patched" methods falsely claim, and the actual safe procedure (which still requires a PC for reliability).
However, this requires a stock boot image to patch. If you are doing this on the same device, it is difficult without a PC to extract the stock boot image from the firmware.
Workaround: Download the full firmware for your phone on the device, extract the boot.img using a file extractor app, and patch it using the Magisk app, then flash it using a terminal emulator or recovery.
The Only Reliable Way (Sadly Requires a PC Once)
If you truly want root, borrow or use a public/library PC for one hour:
Unlock bootloader via Mi Unlock Tool (requires a Mi account, 7–15 day wait).
Download stock ROM for your Redmi 9A.
Patch boot.img using Magisk on the phone itself (no PC needed for this step).
Flash the patched image via fastboot (needs PC one last time).
Method: Root Redmi 9A without PC (if bootloader is unlocked & TWRP installed)
Step 3: Patch the Boot Image Using Magisk
Download the latest Magisk APK (v26+ recommended) from GitHub.
Install the APK (allow unknown sources).
Open Magisk. Next to "Magisk," click Install.
Choose "Select and Patch a File".
Navigate to your extracted stock_boot.img and select it.
Magisk will process the file. It will create a new file named magisk_patched_[random].img in the Downloads folder on your phone.
The Tools You’ll Need (All on Your Phone)
Since no PC is involved, download these APKs directly onto your Redmi 9A:
MTK Easy Su (Patched Version) – Exploits MediaTek processors (which power the Redmi 9A) to force root.
Magisk (Patched for Direct Install) – A version modified to bypass bootloader lock.
Terminal Emulator for Android – To run manual commands.
Root Checker – To verify success.
Where to find them: Avoid random file-sharing sites. Use trusted forums like XDA Developers or GitHub repositories. Search for "MTK Easy Su patched Redmi 9A."
4. The Only Verified Root Method (Requires PC)
If your goal is truly to root a Redmi 9A, the standard, safe process still involves a PC:
Back up data (unlocking bootloader wipes all).
Request unlock permission via Xiaomi’s official tool (requires Mi Account + 7–15 days wait).
Unlock bootloader using Mi Unlock Tool (Windows PC).
Flash patched Magisk boot image via fastboot (PC).
Install Magisk app on device.
✅ This method works reliably and is malware-free.
❌ No PC-free alternative exists that is both safe and effective.
