Magisk module to enable L5/E5a/B2a GPS bands on realme/OPPO/OnePlus devices with Qualcomm Snapdragon processors. It has been tested only on realme GT 2 Pro (RMX3301), but it should work on other devices too if there's hardware support.
- Fix OTA updates with module enabled
- Show module version in log
- Attempt to fix triple-reboot issue
- First release
At each boot, it extracts the oplusstanvbk partition, patches it by changing the /nv/item_files/gps/cgps/me/gnss_multiband_configuration property, and saves it in the module's directory.
Then, a loop device pointing to the patched file is created and the symlinks under /dev/block/by-name and /dev/block/bootdevice/by-name are changed to point to the patched block device instead of the original one.
The change is applied only to the current slot, so that you can install OTA updates without problems.
The source code of the patcher is available under src/gnss_patcher.c and is based on libnvbk.
If you want, you can compile it under Windows or Linux, patch the partition offline and flash it with fastboot.
Every dependency is included as a git submodule, so make sure to run git submodule update --init --recursive after cloning.
To compile you need a working CMake environment.
When cross-compiling for Android, the Magisk zip file is created automatically, but make sure BUILD_SHARED_LIBS is OFF.
