    hunterwang , Feb 9, 2020 :
    Hello all, I am have an issue with my OnePlus 3T where after I updated from 5.0 to 9.0.3 my phone wouldn't recognize my pin pattern anymore (although I have been using the same one for years). After a countdown and threat of factory reset my phone finally accepted the pin as correct but instead of allowing me to boot into android it displays "Decryption Failed, your password is correct but your data is corrupt... Etc". My bootloader was never unlocked (I checked in recovery mode) as I understand this error happens to people with unlocked bootloaders. My questions are, does anyone know why this has happened? And #2 is there anyway to get my data back short of taking it to expert data retrieval guys and paying close to a grand to do it?

    Is there a way to sideload back down to android 5 and fix this error?
