Nexus 4 with Ubuntu touch locked for 24140377 minutes!

My phone has locked itself, the lock screen says:

Device Locked

You have been locked out due to too many failed passcode attempts.

Please wait 24140376 minutes and then try again...

I believe the phone is fully updated (OTA9?).

I have important data, so do not wish to reset the phone.

:(

Solution 1:

Is your device in developer mode?

If yes, you could first try copying your home directory, then reset your device, and finally write your home directory back to your device.

edit:

So here are some instructions (untested) how you could backup your home directory:

1. PlugIn your device via usb to your desktop computer.
2. run adb devices; Your device should now be listed, if it is in developer mode.
3. run adb pull /home/phablet/. /home/userName/your/backupDir/. to download the home folder to your pc.
4. Make a coffee until its done...
5. Now you might want to know where your notes are placed? I had success on searching them with this command: grep -r "Some pattern you remember of your notes" /home/userName/your/backupDir/. The output shows the file(s) containing your pattern, i. e. your notes-data-file.
