⚠️ Important Notes & Cautions
- Always use the correct variant (“export” for Global/India). Mismatching CPH codes may lead to boot loops.
- Keep at least 50% battery before flashing.
- A verification failure often means the build is incompatible or you need the corresponding updater APK (especially for EU/Global models) .
- Flashing is at your own risk—incorrect procedures can brick your device.
- You’ll revert to stock OxygenOS and lose root/custom ROMs.
- After flashing, re-locking your bootloader is recommended for security and OTA updates.
