[Q] Device protection question.

If I flash a factory image on my Nexus 6, will the device ask me for my google account, or does that only occur with a factory reset.

If you wipe the data then yes. I assumed since it's gonna be a whole ddffrent OS. Then yed

Click the top link in my signature for info. Especially if you are thinking of re-locking the bootloader.
You should remove your Google account and any security pin/password/pattern lock before hand. Then do a factory reset from settings before you begin. Safety first.

Giffgaff said they'd need the device protection taken off
"Don't forget to remove your PIN or lock code, and any other kind of protection so the phone fixers can turn on your phone and confirm the issue."
However it can be turned on and the PIN encryption is gone, I just don't know whether they will need my google account to get further into the phone seeing as it's a factory image flash. I can't lock the bootloader because i can't see anything on the screen and I cannot force it off without it auto rebooting.

If the screen isnt working, they can see the issue long before getting to boot up. To turn off device protection, you must remove the google account before a factory reset. You obviously cant do this without seeing what you're doing. And you wouldnt want them to have access to your google account. All you can do is flash factory and send it as is. Device protection isnt going to prevent them fixing a broken display issue.

On a PC or any other device with a browser you can access your Google account. Than change the password.
That is the first thing I should do ....

Just remember, you have to wait 72 hours before performing a factory reset after changing your password.

Yes. Two things to do, when sending the device for repair the display.
If possible flash a factory image.
Change the Google password.

Why change your Google password? They cannot get into your Google account if you factory flash or reset.

Because many people has gmail and other passwords in browser's memory and other data.

By flashing the factory image, in its entirety, all of your account information would need to be entered before you could use the device again anyway. After the repair process, when the device is powered on, they would only see the start up screen, as if it were a new device.

True.
OP wanted to avoid access to his device by others. In general it is good practice to change password from time to time.
It is a point of view. Do not rely only on the security of a system.

I agree. That's why in my first response, I said that very thing. However with a broken screen, he could not do this from his device. So it was recommend that he do it via the web. But with the new features of security, you must wait 72 hours after changing your password before factory resetting. I think it's a time issue and the OP wants to get their phone off to be repaired.

Possible intruder on my N6

I have recently purchased a used Nexus 6 and I have just noticed that my phone may be compromised. It took a while to set up the phone as i wasn't getting the original account info to complete the setup, but now that I have run the setup, and set up a 'group' on the home screen that I labelled 'Entertainment' which holds a couple games. I see now, that the label has been changed to 'D's Sacs Was DQ'. Why would this happen and or what can be done to secure my phone? Please help!
Thank you

LMAO! Really?! Did you factory wipe it? Is it stock or boot loader unlocked? Is it rooted?

Flash userdata.img and erase and flash cache.img in fastboot (if you have a unlocked bootloader) and after that data factory reset in recovery and reboot. That all you can you do.

Flashing it to ensure it was wiped of anything on it prior to use, since it was used, should have been the first thing done to it (ensuring ti wasn't locked to an account or you would have issues afterwards).

How do i know if I have an unlocked bootloader? I'm worried if i do a factory reset I'd be locked out if their account is still considered the original.

To get in booltoader/fastboot mode:
1. with adb, type in cmd: adb reboot bootloader
2. Manualy: power down the phone and press both volume up and down + power.

Try logging in and boot the phone with the original account, delete the account and then perform a data factory reset in recovery. Then boot up with your account and that should do it usualy.

Or even easier... do you see a little icon of an unlocked lock at the bottom of the screen when you boot your phone?

Or, something much less nefarious...
I would think that it could be possible you may have placed the phone in a pocket with the home screen showing (or some similar action) and the folder got renamed with random presses that also triggered random words through autocomplete. Been there, done that.

It was me.. I hacked you.. But once I was in, I couldn't think of anything to do, so I renamed a folder. Was gonna key log your bank details but this was way better

I hack phones and change events in the calendar app. Because I like confusion and making people late.

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.

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

Forgot PiN, fingerprint not work after restart

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.

How to use adb ???

Forgot lock screen troubles

Hello all,
I'm in a bit of a predicament. I have an old OnePlus 3t that I have not used for years. The device contains extremely important business information that I need to recover. However, I cannot for the life of my remember my lock screen pattern to boot the device. I tried to remember the password and have now triggered the messaging of "This device will be wiped after 8 more tries."
I haven't updated the phone in years, so it would be on an old version of Android. Is there any toolset that could remove this lockscreen and allow the device to boot?

If you:
1. Have unlocked the bootloader, AND
2. Do NOT have an on-boot password set (a lock screen password is ok)
then it is possible to remove the lock screen password.
So, do you meet this requirement? If you do, then do you have TWRP installed?

I thought my bootloader was unlocked, but I cannot completely remember. When I boot the phone with volume down and power, I see a OnePlus branded screen that is also asking me to swipe the password pattern. I assume this means the bootloader is not unlocked, right? If I try to enter the password on this screen, will it use up the twies that trigger the wiping of my phone?

Power+Vol down takes you to recovery. The fact that it's asking you for a password tells you that the phone is encrypted and has an on-boot password.
So, unfortunately you're not going to be able to recover the data on your phone.

If your bootloader is unlocked, you will always see the unlocked bootloader warning screen when you power on or reboot (before it goes to any other screens.
If you do not see that bootloader unlocked warning screen, the bootloader is locked.

It is definitely locked then..
Is there any known exploit that might be available for the device? It is older and has not been updated in years... Even if there were a way to keep trying patterns without triggering the device wipe, that would be hugely beneficial.

The security features and encryption are very secure. You won't be able to exploit these, to extract your data. They do this on purpose, otherwise it would defeat the whole purpose of data security in the first place.
If the data was important to you; you should have been backing it up. Many easy and free options available to back up your data. I'm always surprised how many folks don't take advantage of any of those backup options. Then they come scrambling over to xda once a disaster has struck, asking for ways to retrieve their data. By that time, it's too late. Don't wait until after the car has crashed, to put your seatbelt on!

If your device is rooted and had twrp, I got a file to flash and it cleans the pattern or password, it safe my life, many times. So let me know. To upload the file.
