Greetings...
I will try to help you...
First, you have to enable the Developer mode on your device, going to Settings >> About Phone >>> Software Information >>> Build Number. When you reach there, tap on it about 6-7 times until you get a message saying you unlocked the Developer's Mode.

Then you will have to go back to Settings again and look for Developer's mode at the bottom of the list.
When you get into this option, you will have to search for Enable USB Debugging and OEM Unlock options, so you will be able to proceed to the unlocking bootloader...
You must activate both, otherwise it will not show on the pre-download screen! If you get a popup warning, tap enable if you would like to proceed.
Now restart your device into Download mode, pressing Vol Up+Vol Down+Power Button or just Vol Up+Vol Down and insert your usb cable into the device. The usb cable must be connected on your computer first.

After doing this, your device will go on Download mode and this screen will appear, pay attention carefully before press any key on you device....
After you do this procedure to press and hold Volume UP button, then it will show you another screen, like this...
Now you press Vol Up to unlock or Vol Down to give up and go back to normal.
If you choose Yes, your device will reboot and then will erase all informations and files you had into your phone and will perform a hard reset to factory default, and your bootloader will be unlocked.
If all were done correctly, this is the screen that will show for you from now on...
You're done. Your device is completely unlocked.
In any case, always have an original stock rom firmware of your device, so you can restore the original.
And if you want to lock it again, do the same steps again, but when you choose YES, it will do a hard reset again and go to factory install, erasing all again.
Remember to do a back-up of all your data and stuffs before you perform this.
I hope I had helped with this.

Problem with Motorola Moto G 3rd Generation.

Hi, suddenly my device is not working fine. These are the problems.
-Can't see my notifications;
-Can't see my lockscreen;
-The home button doesnt' work;
-Factory mode isn't available, it says that there is no command.
I tried to unlock the bootloader from the Motorola site, but in the last step, when I enter the unlock code, it fails and tells me to enable the USB debugging. I tap seven times to the "number build" but nothing happens. I have the developer options but when I tap it the page is blank with no options. What can I do? Can somebody help me please?

Try a proper external Factory Reset
Android 5.x (Lollipop)/Android 6.x (Marshmallow) Steps
With the phone powered off, press and hold the Volume Down button and the Power button at the same time until the device turns on.
Press the Volume Down key to highlight Recovery mode.
Press the Power key to restart into Recovery mode.
The screen will display an Android robot with a red exclamation mark. (ie. No Command)
While holding down the Power key, press and release the Volume Up key, then release Power.
Use the volume keys to scroll to Wipe data/factory reset and press the Power key to select it.
Scroll down to Yes - erase all user data and press the Power key to select it.

Unlocking the bootloader does not require ADB at all, it only requires fastboot and OEM Unlocking enabled in Developer options.
Please check!
Please tell me, if these are the problems you observed:

If yes, please tell if your device ran out of flash memory.

Thank you very much. Problem solved.

Cannot unlock bootloader

Hi I'm hoping someone can help or at least point me in the right direction if i've missed a thread, i'm on Windows 7 64bit.
I appear to be stuck in a boot loop on my original Shield Tablet, stuck on nvidia screen when i try to go into recovery mode i get the "dead android" picture.
I have tried to unlock the bootloader and i get FAILED <remote: <>, device shows up under fastboot devices command, device shows up as Android Bootloader Interface in Device Manager.
I've searched the forums and seen this problem but everyone else seems to be able to unlock easily, this is the same but no replies https://forum.xda-developers.com/shield-tablet/help/nvidia-shield-unlock-bootloader-failed-t3178865.
Any help anyone can give me would be appreciated. Thanks in advance.
Check the recovery images section for your device here: https://developer.nvidia.com/shield-open-source
Instructions to unlock the bootloader:
Unlocking the Bootloader
Your SHIELD TABLET may have shipped with a locked bootloader. To update the device,
you must unlock the bootloader using the following:
- fastboot oem unlock
- Press the "Volume Down" button to select "Unlock bootloader" option on device
- Press the "Power" button to confirm the unlock. Your device's bootloader is now unlocked.
Click to expand...
Click to collapse
You need to already have adb set up and the Shield connected to the PC to do this. If you don't have USB debugging enabled, this may not be possible, but you should still be able to get into recovery by booting the tablet with Vol- and power button (hold volume - and then just press the power button, don't hold both at the same time).
Yes I've tried that (I know the steps of unlocking the bootloader) that's when i get the FAILED error. When I try to enter recovery I get the "dead" Android picture.

I do it, but the phone is bricked in that screen and reboot, i can't enter in nothing, so the phone dont work now
Hello, ShaineDiaz.
Can you enter to the dload mode by pressing Volume UP & DOWN key simultaneously while restarting?

Possible or Not? Factory reset bricked Pixel 2.

I've spent hours searching and cannot find a definite answer to my question. I see others have asked HOW to fix this issue, I just want to know if it is possible.
Is it possible to factory reset my device or not?
Bootloader is NOT UNLOCKED, and I am stuck on bootloader screen.
"Bootlinux Failed: Not started" when trying recovery mode.
"Slot Unbootable: Load Error" when trying to start.
My device is obviously not found under adb devices as it is locked, but does show up in fastboot devices.
My computer does recognize the android device as well.
Is it possible to factory reset my device or not?
Is there any way to flash a custom ROM and get it operational?
I'd say you're out of luck, I've had the slot unbootable error/ authload error and both usually require re flashing the bootloader, radio, boot.img or a full factory image restore via flash-all to restore via an unlocked BL. I haven't seen any other methods available for the walleye with a locked bootloader I can offer either.

Thanks for your reply,
Surely Google or some super nerd would know how? But I think I am also out of luck.
Thanks though.
Hi! I don't know if could helps, but did you try to sideload full OTA through recovery mode? This should be go with locked BL too, but I am not sure if you have to have enable usb debuging...

Hey Somin,
I haven't fully looked into that option yet, started to give up. But I can't access recovery mode or even get out of bootloader, and usb debugging is not enabled, oem is locked.
If you have any further information or ideas I would be really keen to hear.
Thanks,
Alex

Did you tried to get to recovery from bootloader screen or with key combination too?

I do appreciate your help, but as I just mentioned, I am stuck in bootloader screen and get errors when trying to access recovery, download, start or any other option. Obviously using the hard reset only brings me to bootloader where I am stuck.
Is this what you're referring to with key combination?

Hi! No Shut down your phone and try "the game" with power button and vol+ btn... I didn't find any tutorial and it is slightly lottery, but you could get directly to recovery mode if you will press this btns in correct way:
- try to hold them for long time
- try to hold power btn and quick pushing vol+
If you will get to "no command" screen, press again pwr+vol up and you should be in recovery mode. Good luck

Interesting, I get the same error message as I do when I try to enter Download Mode. So this is different than the power and volume down, and different than just restarting it.
So far I just keep getting back to bootloader screen saying operation denied. But might keep trying it here and there haha.
Thanks for your help.
I had the same problem. I was able to solve it by selecting the download mode in the bootloader. There was an error message. Then I fastboot flashing unlock on the console. Then the bootloader is unlocked. No idea why this worked.
Maybe this will help someone who encountered the same problem.

Need help with my Google FRP locked [non-rooted] LGL455DL

I made the mistake of Factory Resetting my phone after a few failed attempts at remembering the Pattern to unlock the phone, in doing so I ended up being stuck in the set-up process because I forgot the Google account I was logged into on it before the Factory Reset, had been an account I just quickly made on the spot months ago just to set up an app on it. I'm posting here for help with this since I'm on day 4 of trying to find a way to bypass this and my head is ready to explode. I feel like someone with a fresh mind would be able to point me in the right direction.
If anyone can let me know if I'm doing something wrong or missing some steps that will help me try any one of these, or honestly any advice at all... I'd very much appreciate it and it'd help relieve a huge chunk of this ridiculous headache this has all been.
Thanks in advance!
What I've tried thus far --
- I know for most ways around this, USB debugging needs to be enabled. But since I cannot get past the initial set-up process, I can't access the settings to enable it.
- I also know that for a lot of Android devices USB debugging is enabled by default in Recovery Mode but everywhere I've searched for the hardware combination to boot into Recovery/Download mode, all say the same thing:
Turn phone off > Power up with Vol. Down + Power button until 'Download Mode' is displayed (for boot into Download mode, while holding Vol. Down + Power button plug OTG cable into device)
- My problem with this is that on my device, Vol. Down + Power button, restarts the phone. So instead of 'Download Mode', I'm just restarting the phone over and over again. I was able to get my phone to boot into was Safe mode using the Power button + Side button.
- I've also tried getting around this through a series of steps which involved the 'TalkBack' accessibility feature, but when I try toggling to enable it I just get a message saying "Complete setup first to continue"
From there --
I started looking up Stock ROMs that I'd be able to just flash the firmware. But for the life of me, I cannot seem to find anything for this device. And this is where I'm pretty much at now.
To remove FRP lock you boot into phone's Recovery mode and apply
1. Wipe data
2. Factory Reset
Every Android device gets shipped by default with Android Recovery.

I can't get my device to boot into Recovery mode. Everywhere I look up, it tells me to Power off device, then Press Vol. Down + Power key until the menu appears. But on my device, all that combination does is force the phone to restart.
