So I am a developer, making a lockscreen app. Part of the app allows it to set a system lock for double protection. Upon doing this, it set PIN needed for phone to start up. The pin I had set wouldn't work so I entered it in too many times and it wiped my device. The weird thing is, the default password "0" worked in TWRP but NOT to boot Android. Now, after it wiped my device, it boots up to the Android screen, and tells me to enter my PIN again.. It still doesn't work, but tells me in -1 attempts my device will be wiped. How can I just get this all to go away and start again? I have root and TWRP installed. Is there anything I can do?
I can't even boot into Android because it asks for the PIN, even though it already wiped it. I can't use my phone at all.
Flash factory images?

does it matter? it takes 10-15 seconds to flash twrp, or reflash. but anyways i have a feeling that itll ask again, i hope not.
Yea. I would fastboot erase and reflash everything. If bootloader is locked you are hosed.

Contact the previous owner for his unlocking gesture or code/pin and Gmail account, then factory reset and login with his account and when done delete this accoubt in /settings/accounts/. Then data factory reset again and it should be fixed imo. Or send your phone to the prev. owner so he can do it himself. Look here too http://forum.xda-developers.com/nexus-6/general/guide-properly-prepare-nexus-6-resale-t3104504.
I've had this phone since it came out haha. I haven't stolen it or anything. The problem came because I was solely testing on Samsung devices. Here, I set a backup PASSWORD in case you couldn't unlock your phone. My app was a device admin so it had the ability to set phone lock and lock the phone. What happened was when I tested it on my Nexus, between making the password and setting the password there is the option of "require at boot", which mysteriously, my app automatically selected. Now the issue comes in when I rebooted my phone and Google did NOT let me put a PASSWORD it, but required a PIN. This was an impossible scenario because the android lock screen was set with a PASSWORD, not a PIN.
The even weirder thing was that my app automatically sets the backup android pin to "0" if no backup password is set. When I tried 0 at boot it wouldn't work. BUT when I tried it in TWRP 0 was the only thing that decrypted the phone. I am still not sure why this whole thing happened (Google not letting me put a PASSWORD instead of a PIN if the device is encrypted. My app automatically selecting require PIN at boot, and the backup "0" working in TWRP when it wouldn't work to boot Android).
So @gee2012 I know it may seem like another thread where someone stole a Nexus and wanted to break in to use it. But I assure you I am the only one to ever own this phone. This was just a weird scenario that hopefully won't happen again.
But for the sake of the question:
Flashing factory images worked! Thanks @HolyAngel

Who talked about stolen devices mate, I surely didn`t! I thought that you bought a used Nexus 6 mate, and the previous owner didn`t delete his account :silly:

Oh sorry :/ haha. Wasn't sure if it seemed that way. But nah this has been my baby since unboxing lol
Today a scenario popped up and I quickly set up a 4 digit PIN code and pressed enter. As is on stock Lollipop 5.1, I'm required to enter password twice to confirm. So I did (and as far as I could tell, it was four digits, from a quick glance), but then when I wanted to unlock, it wouldn't, typing in the same passcode that I thought I'd typed in (and the one I used previously when it had a screen lock, disabled it in June). I've tried to brute force my way through, up to almost 300 attempts, but no luck. There's no forgot password option, at least not in plain sight, and Android device manager was no help (it locked the phone, but I could press home and I'd just be back at the lock screen). ADB is disabled. PC doesn't recognize phone. Does anyone know of secret tricks or programs that can brute force through for me? Thanks!
Do you have your bootloader unlocked and a custom recovery? As long as you didn't enable encryption with this code, you should be able to use recovery to backup files from your phone... However there is no way for you to get into your phone without the code. So after backing up, you would need to factory reset it. As far as brute forcing goes there is no way for you to do it. You would have to enter every combinaton that exists manually. That would take forever... So factory reset is your best option.

No custom recovery. Encryption isn't on. Is there an app or hidden Google solution for this? (I'm in denial right now, ha)

You said no custom recovery... but you didn't say if your bootloader is unlocked or not. If it's unlocked, you are in luck and can flash a custom recovery, then backup your files. If it's locked... No choice but to factory reset.

Sounds suspicious... You did enter the 4 digit pin, but cant get it unlocked with those code? Is that your own phone or others? Sorry, but your case is very strange...

Absolutely is my phone. I entered it so quickly i may have mistyped it. And no, bootloader is locked.
Normally there is an option to put in your Google email and password if you forget your password

Not there in Lollipop. Apparently they took it out. Because it only shows emergency call, below the numbers where it used to be in KitKat, and the dialog box that prompts you every 5 failures will only warn you and have an OK button.

That's stupid of Google to do that. I guess I would do a nandroid backup and factory reset if I forgot mine.

I am on 6.1 and I went to reset my phone it is locked I havent done any modding to it. it went into recovery and said erasing for about 10 minutes so I went to restart the phone and now it says i need a password to start it. But I never had a password. Any way to get this thing back up and running. It is oem locked
After a reset you need to enter the password for the Google account you used on the phone prior to the reset. This is to verify that it's your phone...
At some point a password was set. The only way you would be prompted to enter a password is if you had set one at some point in the past by setting up a Google account.
You need to know that password, as it's the only way to get back into the device. If you don't know it for whatever reason, you're screwed.
Dear All,
I have a friend with Huawei P9 Plus with this Firmware VIE-L29C636B103, i don't know what is in his mind on that time but unfortunately after restarting the phone he forgot his PIN to unlocked the phone and the fingerprint was not working. As far as i know, the only solution is by Factory Reset the phone, but he did not want to loose his data. Is there any way to solve this problem?
Thank You

No still original without custom recovery. Can i use TWRP to backup first the data ?
The problem is that you not unlock and then root yet. You basically can't use TWRP. If unlock bootloader, the phone will be immediately wipe data.

He or you could've used it to delete ". key" -files through adb. But that is only useful to have access to the data. You can't set new fingerprints or delete any of them because he must know his forgotten password for it. So it would only be a temporary solution.
Unlocking the bootloader never erased my data. It couldn't cause of some failure appeared at let's say 30%. But I'm not certain that the failure appears also on his phone. Which leads to my suggested solution:
He should try to remember the password and include any typos(yes, typos. My pin was 85320 but it also happened that i typed two times the false pin. The outcome was 85350. Huawei's layout was kinda bull**** and vulnerable for that type of failures. At least to me.) As I know it must be a PIN, not a password. If that fails get rid of the data and make a factory reset.
Thank you all,
Today i connect the P9 Plus Phone USB to HiSuite in Windows 10, i just leave this around 5 minutes and suddenly it connected to HiSuite automatically. Now i'm still backing up the data pictures, etc. Still wondering why in windows 10 it can connected automatically than in windows 7 After backup finished i'm gonna factory reset the phone.
My mistake on comments on unlocking bootloader will erase date since I mixed up the process. Now I remembered that after unlock, if you proceed further to root the phone, the phone will have to erase the data immediately. No option for you to choose not to erase data during rooting process if not mistaken. That's why I dare not to root again the phone.

Delete (or rename) the following files inside /data/system (note that probably not all of them exist for you, simply delete those you can find):
password.key
pattern.key
basically any .key file in that folder
Using TWRP file manager (its under advanced)
Thanks man. Problem is, I could only see my device on PC if phone was started via twrp. If not, device shows on PC when plugged in but won't show any files.
I have booted phone into recovery, seems that it will let me do that. Is that any help?. Mrs has just come back from work.... Gulp!
Ohhhhh maaaaan. You are the don!!!!!. I'm in now, you sir are a star!. How can I now get the phone back to having password?. Have I buggered it as I deleted the files??

nope just open settings, security and choose a new lock method. might be a bit buggy, if it asks you for an existing pin whilst setting the new lock screen either enter anything or leave it blank. then set your pin hit thanks if i helped

Hmm. Not going so well now. I'm doing the following:
Security> screen lock. 'Confirm pin'. I enter a pin, then either a) press 'OK'... Screen goes back to 'security & fingerprint' screen. Shows 'screenlock none'. Or, if I try to previous then press forward arrow on keypad (rather than pressing OK), it goes to blank screen with left facing arrow at top of screen saying 'choose screen lock'?.
I've also noticed that in security & screenlock screen, it shows 'finger 1' under fingerprint list. Like it still has a fingerprint saved.

Yeah the fingerprint will be saved, i cant remember exactly how i did it (i'm not doing it on my phone as my bank already hate me for being rooted and registering android pay like 20 times a month) - if i remember i enter a pin, then choose either pin again or none, and after none go back to pin. I think that worked, but don't hold me to it - it's easy to recover i just dont have a device in that state to try. I could teamviewer your phone if you want me to and sort it haha. Just have a mess around to see what happens, one combination of that should work. Basically android still thinks you have a pin, but it's physically not there.

Tried every combination of fiddling that I can. Wondered, if I dirty flash copy of OOS 4.02 over current ROM, would it sort it?. Would I lose root & unlocked bootloader etc if I do this?
