Without a google account there is no FRP and therefore no OEM enable needed.

Figured it out, you have to hold volume up on the bootloader screen. Thank you for helping me.

Stuck at Gmail verification

Hello
I have been running official android m on my Nexus 6 with unlocked bootloader. I just used Nexusroottoolkit to flash the official android n factory image and then I locked my bootloader. Now when I boot I have to verify my gmail to use my phone. And I have no idea what gmail adress I used. I haven't changed the password on the gmail I used. What should I do?
Remember your email address. Because when you locked the bootloader - a foolish thing to do - factory reset protection kicks in. Unless you can recall which account you used you'll be locked out of the device.
Is there nothing I can do?
Find a way to bypass FRP.

When making a new Google account the system will check the username.
Do not activate a new name, but try to find an existing name. Maybe it helps to remember your forgotten Gmail account.
Some people remember things with the help of a hypnotist ?.
Don;t give up remembering.
Thanks for the replies!
I will never remember the gmail i used, it was a random mix of numbers and letters
I have got into the phone and I can install apk's but there are no methods to get rid of the FRP on android 7.0 yet. (security patch October 5)
Is it possible to sideload the stock 6.0.1 image from the stock recovery?
Or is the only option to replace the mainboard?
If you're in, turn on OEM Unlock in developer options and then unlock the bootloader. This time, leave it unlocked and keep OEM Unlock turned on!
Doing those two things will ensure FRP doesn't bite you in the ass. And next time, use an email address you can remember.

Great idea! It would defiently help if I would find the Gmail account since I know the password for it. Where do I find devices.android.com? I didn't find it in Android/data

I don't think you can downgrade your bootloader, I think the only way is to install the next developer preview bootloader and then you would be able to downgrade it to an earlier version
CF autoroot has bootloader unlock option. worked for me when I had to unlock my bootloader after nougat OTA update in order to root.

On n OEM unlock should be activated by default, what happens if you fastboot flash n factory image step by step with no simcard inside?
does booting into fastboot and type fastboot oem unlock not work?
Otherwise there are a bunch of YouTube bypass frp videos, did you try anything?

He has a N6 where he's locked out of the device and unable to activate it. Either he forgot the email addy and password he used to activate it, or he purchased a phone from someone else and got locked out because that someone else didn't remove their account from the device prior to selling.
In any event, his legit options are to try and remember the email and password used, or to try and get the seller to remove their account from the phone. Otherwise he'll have to try and bypass the FRP.

as you do the factory reset bypass protection, you need to do a downgrade to an older version android, then bypass, and update to the latest version

I tried all solutions for bypass and other sources after youtube, but as the nexus the whole time comes the first time Android the newest and latest security patch, if I remember correctly at the October 5th when it came out the official version 7.0
@bombonel: With Factory Reset Protection in play you must know the email address and password used on the phone in order to progress in the setup. Entering into the bootloader in the phone's current state and attempting to unlock the bootloader using fastboot will not work. Unless you can get into Android and toggle the Enable OEM Unlock option in the hidden Developer Options menu you will not be able to unlock the bootloader.
Your available options are as follows.
You need to know the email and password used on the device.
If the device was purchased used from another person, you need to contact that person and have them remove the device from their account.
You need to start looking at methods of bypassing Factory Reset Protection.

I talked to the person from whom I bought the phone arrived in this State, the person from whom I got did not know how long does factory reset after 5 minutes of thought got stuck and enter to recovery ans wipe data and cache wipe, having the account and all saved and knowing that the first boot takes thought and got stuck and to give it to me , started that night fix to change the password to your gmail account and deleted and sync and all of his account and the phone became useless. Because it communicates with google server over the internet, but only synchronized with the old account and no password only, and tried to contact the folks at google and with whom you can, but make no result if the wrong person irreparably.

T817A FRP locked

***Solved***
First Of all I want to thank you all for helping me out.
So it was google that updated their Google Account Manager apk so you can't login in this way In order to make your device "thinking" that this is the last account that was synced with the device.
and I realized that I should get some older version of GoogleAccountManager In order to fake the frp lock but the current version is blocking any older installation of it. In my case GoogleAccountManager 7.0.24 blocked the installation of GoogleAccountManager 6.0.XX(think it was 23).
So I decided to go a little rough on it and Downgraded the whole device Android Version (found a stock 5.1.1 for t817A model) In order to force the GoogleAccountManager application to downgrade also.
Some people complained that the FRP blocks their try to change android version but it wasn't my problem so I don't know how to help here.
after the downgrade I was able by using QuickShourcutMaker then opening GoogleAccountManager to login my account (many tutorials around the web), restarted the phone and TADAM, works like charm
My dad bought me a used one for the New Year (as I wished) and unfortunately it is FRP lock.
SO I've searched on how to disable this lock and I found I'm able to open google chrome settings but with no success further.
I've seen people enabling USB debugging then some how disabling that lock but I think google blocked my access to developer options so I think I'm pretty stuck ..
also, I have the option to send it back to the store overseas but I would like to try saving some time and unlocking it by myself so any ideas guys?

Search for an app called QuickShirtcutMaker. Download, install and run it.
Type ACCOUNT in the search field. Look for SETTINGS(add an account) then tap Try.
Create a Google account then log into it.
If it creates the account then you should be able to use the new account to bypass the GOOGLE login.
Reboot first.

Ok, so it seems like my Google Account Manager is 7.0.24 version, and it disallows me to add a google account through QuickShortcutMaker.
Many site's are telling to Reinstall to older versions of GoogleAccountManager but when I try to install any older version that I found it says "The package appears to be corrupt".
Now im feeling stuck agein but thank for the fast answers 'till now :good:

Yes but i can’t enable it at all because i am bypassing the google account so its not available i need to enable it in another way which I don’t know about
Know the username and password. That is the only way to get to Developer Options to enable OEM unlocking.

Mdm google pixel 5

Hello,
I bought a second-hand pixel 5, after using it for a few days I wanted to reset it and I ran into an mdm lock, is there a solution?
thanks in advance
MDM meaning Mobile Device Manager?
Go to Settings > Security > Device Admin Apps, and disable whatever is in there. If that agent was still present after a factory reset I would highly recommend flashing a factory image with the Android Flash Tool, after you've enabled developer options and USB debugging.
Will try and repport, ty for the reply
Yeah it mean mobile device manager

Are you able to remove the MDM app?
Unfortunately, the ability to unlock the bootloader is set at ROM build time, so if you got a device that was sold to a particular enterprise, for example, they may have specified that ability to be disabled. That also may mean that the MDM app was baked into system, which means that a factory reset won't remove it.
Still....you can try rebooting to recovery and try to perform a factory reset there, although I suspect as I mentioned the MDM may actually be integral to the firmware.
yeah the app is bakeday firmware as you said, there are a bypass trick for android 11 but yesterday i got the ota and i m stuck on set up screen with a google authentification and no workaround to bypass this cheat

Please read this thread. If you buy an enterprise device, it will likely have an MDM app baked into the firmware that you cannot remove without root; unfortunately, root is not possible without unlocking the bootloader, and unlocking the bootloader is not possible if OEM unlocking is not allowed in the ROM.

What works? Your question isn't clear.
Again: If you bought an Enterprise device, it is likely that you will NOT be able to remove the MDM app or root the device - regardless of the Android version.

My phone with mdm was working good with "verizon cell unlock" method (via adb) on Android 11.
For Android 12 that method is not working
I searching for another solution.
Now I removed com.android.vending (play market). Without play market device working well, but...no market.

By "unlock" do you mean bootloader unlock, or carrier unlock?

It is an enterprise device - meaning, as I've pointed out, that the MDM app is integral with the firmware. This, coupled with the fact you cannot unlock the bootloader, severely limits what you can do with the device.
If you're specifically asking about carrier unlock to use it on a different carrier, that is a different topic that needs it own thread. Please do not hijack threads with off topic comments.

Help me understand. What exactly are you trying to accomplish?
I just bought a used Pixel 5 and encountered an MDM lock. Phone was functioning fine on A11 but after upgrading to A12, the following message pops up and won't let me continue using the device:
"Your device controls by admin, all data will be wiped in 2 hours".
Resetting my device doesn't help, the same error comes back during Android setup.
The good news is that after contacting the seller they assured me that they will contact the original enterprise owner and that MDM unlocking can easily be done remotely. Bad news is that I'm assuming even after MDM unlock the bootloader will remain locked since this device obviously didn't come from Google directly. But fingers crossed.
