Some users (within legal boundaries) use patched NV files to remove factory reset protection (FRP) or Mobile Device Management (MDM) locks that persist even after a full wipe. This is because some locks are stored in the NV region.
Warning: Modifying NV data can permanently brick your device’s cellular capabilities if done incorrectly. Proceed only if you know exactly what you are doing.
adb shell
su
dd if=/dev/block/by-name/modemst1 of=/sdcard/original_nv.bin
(Partition names vary – verify with ls -l /dev/block/by-name)
Before any modification, use MiFlash Unbrick Tool with “Save NVRAM” option. A self-made backup is always safer than a downloaded patched file.
