    My phone suddenly rebooted and it is telling me that it needs a decrypt code but i don't have one and the phone can't be turned off and it is stuck on a black screen with a minimalist keyboard and the Oneplus logo. This happened while the phone was on standby. One Plus 8 pro
    You have to enter :
    code pin or password (yes number passwords still work)

    Did you try your phone PIN or password that you might have set ?

    I have just done an update on my oneplus 9 and I am now stuck on this decryption screen too.
    I only have a password on the phone there is no code on the SIM card or anything else I have entered the password multiple times and tried resetting using the Volume Up button and the power button but it just comes back to this screen again

    I'm having the same issue w/my OnePlus 9- it restarted & has been stuck on a decryption screen requiring a password/passcode that I never set. Even still, I attempted the only password/passcode I use & it doesn't work. It's done this once before randomly & I entered the same code I entered now & it's not working. Customer support has also not been able to help. They keep saying they're sending emails to request the IMEI/OS version & proof of purchase (which I'd gladly provide) but they never send the email. Brand new phone & it's unusable.

    If you are unable to use your password, you might need to use an brick tool from here:

    Be careful as this will wipe any data on your device and do a fresh installation of the software at whatever version is contained in the msm tool.

    Is there maybe an update on this? I'm having the same issue on a 8T which ran out of battery, I fully charged it and when I turned it on it started asking for a password. There's no option to use a fingerprint authentication and the phone's password doesn't work. There's a forgot password option but it comes with the warning "You will LOSE everything(Music, pics, etc)" and I do not want to agree with that.
