Forgot PiN, fingerprint not work after restart - Huawei P9 Plus Questions & Answers

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.

Device Protection on Android One Useless

I was under the impression that device protection on lollipop for android one devices would work no different than nexus devices .it turned out to be untrue. I was using stock 5.1 lollipop (encrypted) with no changes to the bootloader or recovery. On downloading the 5.1.1 update I went to recovery amd factory reset the device and flashed it with OTA zip file 5.1.1 . I was then able to go through the setup screen on first boot without it asking me for me google credentials of the previous rom.
Thus proving even if your device is looked and encrypted it can be easily reused by flashing the rom.
that happened because you formatted data sir and do one thing re encrypt THE device and wipe data again see what happens

Thats the point.. thats exactly what a thief would do ie format the data and use the device again.Even after format it should have been locked to my google account.
You don't really get the point of the factory reset do you? The point of the factory reset is to wipe everything and set the phone to the factory conditions. That 'everything' also includes your google account. Name one device that keeps an account that it signed on to after a factory reset, I'll name a unsecure device. Even nexus devices don't do that.
Try not to lose you phone.

My dear friend let me explain the point to you. Device protection for lollipop devices acts as a deterrent for thieves. In case you loose your phone, for a thief it will be nothing more than a paper weight . If you read the first post . I forcefully cleared the phone from recovery just as a thief would do because he wouldn't know the unlock code. However on setting up the phone I should have it hit a dead end because the device should have been locked to the google account of the previous user.
Here read this article to know how it works..Hopefully then you will get the "point" http://www.greenbot.com/article/290...ow-about-device-protection-in-android-51.html
Besides device protection will not work on your phone as you have unlocked the bootloader and replaced the stock recovery which defeats the purpose
pardon my ignorance then...
apparently this feature is only working on N6 and N9.

still if a thief knows how to do a factory reset, he's also able to flash a custom rom or reflash the stock rom without having to login in to the device. Which is really easy process with most phones out there.

This is where the locked bootloader comes into play, an average user wouldn't tinker with the bootloader or stock recovery. To install a new rom one has to unlock the bootloader . Now for a thief he wouldn't be able to unlock the bootloader because the stolen phone will be already locked with the pin even the usb cable won't work. So all he can do is factory reset the device ...had device protection been working as it should have he would have hit a dead end there as well.
Don't know why google didn't enable this feature for android one devices .

Can't get into Nexus 6 that has encryption

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.

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:

Phone blocked

Hi Guys,
I think I have no lucky these days...
I was testing a new ROM and when a returned the backup with TWRP android asked me a patteren for unlock.
The patter I usauly use dont work.
I found a help that say to erase some files in /data/system but it doenst work...
I had a idea to block the cell with my google account and set a new PIN for unnlock... It doenst work
Now I have the cell blocked by google and its impossible to access the internal memory with TWRP...
I need help... I dont know what to do...
Please !!!!
Sounds like your only way back is to format/delete all your data and start from scratch. You can use fastboot to do this.
I think this is the way... but I never did this before...
Do you know a step by step to do this !?
If I understand rightly you have a Google locked phone. I have not tried this on the OP3T but if you are able to reach the boot up screen where Google asks you for the password/pattern lock, you can try inserting an OTG drive of any capacity into your device. The phone will ask for changing storage. After clicking 'OK' you will be taken to the storage section. Go to 'Apps' and from there to 'Setting'. If you are able to reach this far, do a complete reset from that 'Settings' section and you would be able to recover your phone. I repeat, I have not tried this on the OP3T but have successfully tried this on some other phones. Best of luck and hope you get back your toy.
Let me also add that you won't be able to recover a Google blocked phone by factory resetting from recovery. The only way to do this is to reset it from the settings section of the OS itself after you have booted up.

Lost pin code... How to unlock phone?

Help.. I have a Huawei P10 (VTR-L09) with Android 8.0 and stock rom and recovery. I've lost the pin code and now it requires the pin after a phone reboot... So I can't access my phone anymore.
Every solution I find on the internet is either only for Samsung or not supported for this phone. Does anyone know how to unlock it now?
Please note that USB Debugging is not enabled in settings as I got the phone back from repair only a few weeks ago so only got fastboot commands. But I really do not want to factory restore it...
Thanks for any assistance!
You could contact your Phone company and tell them you've lost your Pin and PUK. They only need the Numbers from your Sim-card.
Thx for your message GAMaus, but I've lost the phone pin and not the SIM pin. Do you think they can really help me with that?

my friend was with the same situation, he goes to service center and they fix it but he lose all data.
or try with some gsm repair service maybe they can unlock without losing any data, but if your device is encrypted in my opinion is not possible without factory reset
It's not possible to unlock your phone without the correct PIN. Only chance to get into your phone is to wipe data in eRecovery. But this will remove all your user data except the data on SD.
You're also not able to get your data through TWRP because the /data partition is encrypted. To decrypt, you need your PIN.
But there's one question I have: The P10 has a great fingerprint reader and you're telling me, that you didn't assign your fingerprint for unlocking your phone?

he probably was forced to put his pin because of that 3 days option

Yeah the fingerprint doesn't work after startup because Huawei wants you to remember your pin... But fortunately I could try endless possibilities with the pincode (only sometimes I needed to wait a few hours). But in the end I got the pincode correct, so I can use my phone again
Thanks everyone!

Look in 9 pro forum. I think an adb command can remove the pin code via bootloader.
But this is frowned upon bc you may have stolen a phone etc.

I think that stopped working a good while ago.
If you forgot your PIN only option is a full phone wipe I'm afraid.
