I have install Ubuntu-touch on my Nexus 5 and everything worked alright. Until today I had set up a 4 digit locking password, that worked. I changed it to a "regular password" but once changed I could not log in even though I am confident that I use the same password. ADB does not seem to work since I guess I would have to unlock the phone first.
Is there a way to recover the account or change the password ?
I see the recovery has a "wipe data / factory reset option" but I don't find too much documentation about it. What will be the state (wrt system and apps updates) of the phone afterward ?
