Oppo R9s Global Firmware !free!

Only custom "Treble" ROMs. The official Global firmware will break the fingerprint sensor and touch screen. Search for "LineageOS for R9sk" instead.

This is the golden rule. Flashing firmware will almost always wipe your internal storage. Photos, contacts, messages, and apps will be deleted. Use Oppo’s built-in backup tool or transfer everything to a PC. oppo r9s global firmware
