- Backup: Always create a full backup of your device in TWRP before making any changes.
- Risks: Flashing custom recoveries and unlocking bootloaders can void your warranty and may lead to data loss or device bricking if not done correctly.
Troubleshooting
- Device Not Detected in Fastboot: Ensure you have the correct USB drivers installed for your Oppo A5S.
- Bootloop: If your device gets stuck in a bootloop, try reflashing the stock firmware using the official Oppo recovery tool.
- No TWRP for CPH1909: If no official TWRP build is available for your device, you may need to wait for a developer to create one or consider using an alternative custom recovery.
