I have Oppo F1F, 2 days ago suddenly some of its apps stopped responding, I switched it off to restart again, but, it did not start, and asked for restore, and showed that system file was encrypted, which I never did by myself. And to wipe all data to rest the phone, it requires a password, which I have forgotten. Is there any solution to this problem? How can I reset my phone while I don't remember the password but the phone still demands a password to decrypt the system file and wipe the data for factory reset!!
