Viwoods AiPaper Mini suddenly stopped accepting my lock-screen passcode

tanjo · Today, 03:24 AM

Hi,
I’m hoping someone here can help because I’m pretty stuck. My Viwoods AiPaper Mini suddenly stopped accepting my lock-screen passcode. I’m sure the code is correct because I wrote it down when I set it up. The fingerprint unlock also doesn’t work at all. This happened right after I had used the battery down to about 12%, charged it to 100%, and left it plugged in for another 30 minutes. I don’t know if that’s related, but before that everything was working normally. I already tried a forced restart and a factory reset, but I’m still locked out. Viwoods support only told me to try other passcodes (???), which didn’t help. Has anyone had the same issue or knows a way to recover the device?

Are you 100% sure someone else didn't have access to it and didn't change the password ?

Yes, I’m 100% sure. No one else had access to the device and no one could have changed the passcode. I set it myself, wrote it down immediately, and the device worked normally with that passcode before this happened. The fingerprint unlock also stopped working at the same time.

Update: It finally worked.

I was able to enter Android Recovery via ADB and perform a factory reset. The strange part was that the first attempts didn’t seem to change anything, and I kept ending up back at the same lock screen.

After several tries, the recovery/reset procedure eventually completed properly and the device started normally again. I can now use the AiPaper Mini again.

So in my case, the device was not permanently locked and it also wasn’t an FRP issue in the end.

Viwoods support provided the official recovery procedure.

Thanks to everyone who replied and tried to help.
