Just wanted to share a quick fix for the OPPO A37m. I ran into an issue where the phone was stuck on the first logo after a "safe format." Even trying to wipe storage from recovery asked for a password. The Solution: I successfully fixed it by flashing the file specifically. Tool Used: UnlockTool (Erase Userdata OK) or SP Flash Tool oppo a37m userdata
: Ensure you are using files specifically for the A37m (MTK variant) and not the A37f (Snapdragon), as using the wrong firmware can "brick" the device. Settings → Additional Settings → Backup & Reset
