In this guide, Root Custom ROMs is going through it gar rapid changes. In the face of increased recognition of Magisk-rooted devices by banking apps, a lot of users are opting for APatch, a method which is based on the KernelSU and has more stealth and stability, along with better performance. This instruction is a detailed coverage on how to root custom ROMs via APatch, enumerating the essential things, the full process, precautions, and possible problems. Use this manual to get the root without any hassle and in a safe way.
🚨 Prerequisites Before You Begin Root Custom ROMs
Make sure you have all the listed below points before continuing with the operations:
- Device Bootloader Must Be Unlocked
- You Need the Correct boot.img for Your ROM and Device
- Avoid Pre-Rooted ROMs or Custom Kernels
If your ROM is already rooted using KernelSU or ships with a modified kernel, APatch will not work and may cause a bootloop. - Avoid init_boot.img Even on Android 13+
APatch strictly requires boot.img regardless of Android version. Do not use init_boot.img.
- Avoid Pre-Rooted ROMs or Custom Kernels
🧰 Required Tools and Files
- Android SDK Platform Tools
Download the latest SDK Platform Tools from Google’s official site. - APatch App (Latest Version)
[Official GitHub/APKMirror links or trusted source] - Matching Firmware to Extract boot.img
- Pixel: Use factory image (ZIP)
- OnePlus: Use payload.bin from full OTA
- Xiaomi: Use Fastboot ROM (.tgz/.tar) extracted via 7Zip
🔧 Step-by-Step Guide to Root Custom ROM with APatch
1. Extract the Correct boot.img File
Make sure that the boot image is the same as the firmware that you have installed in your phone at the moment. To verify:
Settings > About Phone > Build Number
Use a proper method to extract:
2. Place boot.img in Platform Tools Directory
This means that fastboot commands can be executed without having to specify full paths.
3. Install APatch App on Device
- Get the latest APatch APK.
- Install the app and allow all permissions required.
4. Patch the Boot Image Using APatch
- Launch APatch
- Hit the Install button (top right)
- Select “Select a Boot Image to Patch”→ Choose the stock boot.img
- Click Set SuperKey→ Enter an alphanumeric key of at least 8 characters
(e.g., Rooted4567)
⚠️ Do not use weak keys such as abcd1234. In some APatch versions, they might get blocked.
- Granting APatch to patch the file
→ /Downloads will be the location of the newly created file, apatched_boot.img
5. Flash the Patched Boot Image via Fastboot
Put apatched_boot.img in your platform-tools folder.
- Turn on USB Debugging on your phone:
- Settings > Developer Options > USB Debugging
- Connect your device to PC and type:
- adb reboot bootloader
- Then apply the patched image permanently:
- fastboot flash boot apatched_boot.img
- fastboot reboot
- ✅ Alternatively, test temporarily before flashing:
- fastboot boot apatched_boot.img
6. Finalize Root with SuperKey Verification
After booting:
- Launch APatch on your device.
- Tap SuperKey.
- Input the key that you used earlier.
Then you should be able to see:
Kernel Patch Status: Working
- Next:
- Tap Install near AndroidPatch.
- Restart your device.
🎉 Your APatch rooted custom ROM is all set.
🧪 Manual Flashing Method (Optional)
Here is a manual way for veteran users w
- Patch boot.img using APatch
- Use fastboot manually to test and flash
- Set SuperKey in APatch post-boot
However, this deeper control method is not necessary unless the auto one fails.
🛠️ Troubleshooting Common Issues
Device Bootloop After Flash?
- The most probable cause is that you have flashed a pre-rooted ROM.
- Solution:
- Reflash original boot.img via fastboot
- Or switch active slot:
- fastboot –set-active=a or b
APatch Fails to Patch?
- Make sure boot.img is a clean stock just as you received it from the vendor without any modifications.
- Choose the appropriate version of APatch app for your Android OS.
SuperKey Not Accepted?
- Confirm that it contains 8 or more characters and they are all alphanumeric.
- Repatch if you forgot it.
📌 Important Reminders
- Always backup your information.
- Do not do any patching to the custom kernel unless you are sure that you are safe.
- With APatch never use init_boot.img.
