Warnings — Read Before Flashing
- Data wipe: Flashing stock ROM will erase all personal data. Back up everything first.
- Correct model: Use only the ROM file that exactly matches your device model number — wrong firmware can brick your device.
- Battery: Ensure at least 50% charge before starting the flash process.
- Do not interrupt: Never disconnect your device or close the flash tool while flashing is in progress.
- Warranty: Flashing unofficial or modified firmware may void your manufacturer warranty.
