Hi. I have the above phone with official marshmallow update and I'm trying to unlock the bootloader. I managed to get a db to work once and got the unlock.bin file from LG. Now I cannot get adb to work again. My device shows up when I start adb but as soon as I reboot into fastboot it freezes and I cannot send any commands to the device it just says <waiting for device>. I have USB debugging enabled and OEM unlock too.
Any help or advice would be very appreciated.
Thanks.

In fastboot-mode, you need to use the fastboot command. Sorry, if you did try this already, should be obvious. Does fastboot show your devicve? -> 'fastboot devices'
Yes I did try the fastboot cmd with fastboot flash unlock unlock.bin and fastboot oem device-id and get the device waiting.
Any unknown or defective devices in device manager? This would indicate a driver issue.
No. All devices are OK. No warning triangles.
Sorry, I'm out of ideas now.

When going through the adb commands and i type in fastboot oem unlock the command window says waiting for device but on the device nothing at all happens.

It can only work in fastboot mode (when off press power+vol.dn).
The fastboot devices command must return your N7's serial number. If not, run it as root/admin and/or install a new driver and fastboot app or use NRT.

Hey new to android and looking for root my pixel 2 xl.
Following this guide https://forum.xda-developers.com/pixel-2-xl/how-to/guide-unlock-flash-root-pixel-2-xl-t3702418
Using windows 10, ADB and fastboot version 29.0.6-6198805, android version 8.0.0 security patch level Sept 5, 2017.
OEM unlocking and USB debugging checked.
Enter command "adb reboot bootloader" takes me into the bootloader screen.
Enter command "fastboot flashing unlock_critical" gives me error "FAILED (Write to device failed (Too many links))" "fastboot: error: Command failed"
Phone resets.
Have searched past threads suggesting to use different USB ports and cables. Tried several cables and every port with no luck. Any idea whats causing the error? Thanks

Yes I tried commands "fastboot flashing unlock" as well as "fastboot flashing unlock_critical". Both commands give the exact same error.
The command "adb devices" does recognize that the phone is plugged in. Also the drivers are up to date.

Then i would suggest that you update your firmware via OTA as Tulsadiver suggested. Then try your unlocking command "fastboot flashing unlock"
The critical one is no longer needed after the 9.0 update. Good luck. :good:

I'm not sure of the difference. The screen I attempt to unlock reads FastBoot Mode in red. Fastboot devices is now displaying my phones serial. Adb devices no longer displays serial.
I cannot remember if I had fastboot mode loaded earlier when I attempted the command "Fastboot devices". It is now displaying serial when enter the command while in fastboot mode.

Fastboot mode, or bootloader mode as some call it, is when you enter it when the phone is shut off with the power + volume down buttons, or from ADB reboot bootloader when your phone is on. ADB devices will not work in fastboot/bootloader mode. Conversly speaking, fastboot devices will not work while your in your OS with the phone on. All your fastboot commands must be done from fastboot/bootloader mode. :good:
I'd try out the pixel all in one tool, it makes these things dummy proof. But really, take the OTA and get your phone updated first.
Hi everyone, I recently bought a 2xl pixel and it's updated to Android 10, and I want to change rom (basically why I like to see how much can be done)but I have the problem that it is Verizon version, I have tried to unlock it with the methods I have seen, but I have seen that it depends on the Android version.I would like to know if there is a way to unlock the OEM unlock in order to unlock the bootloader. My model is the Google Pixel 2XL 128GB. Thanks in advance

Sorry to say, if your device is a Verizon carrier variant (not purchased directly from Google), then you will not be able to unlock the bootloader at this time (or likely ever)....
To be sure:
after enabling "Developer Options" if you can't enable the "OEM UNLOCKING" toggle, your bootloader is not unlockable.

What you are trying to do? Just switch from Chinese to Global? or your device is bricked now?
What did happen after that you flashed the Chinese recovery ROM?
What modes do you have available?
Did you unlock bootloader previously?

Fastboot flashing commands won't work if you have bootloader locked.
Did you unlock bootloader previously and probably get locked again?
Did you enable all the proper options on Developer section, i.e. USB debugging and check if device is recogniced on adb commands?
What do you get with "fastboot getvar all"?

And you said you enabled USB debuging?!? you didn't. First enable it under development tools.
MAKE SURE YOUR USING RIGHT ADB/FASTBOOT TOOLS AND DRIVERS.
After 'adb reboot bootloader' use 'fastboot devices'. You can change usb cable and if you still get errors try using usb hub.
If all above fails than try it on WIN7 PC.

I think you are not properly booted to the proper state while you're trying certain commands. Just to be clear; adb works while your device is power on and fastboot commands will work only while your device is in fastboot mode not while on adb mode. A way to be sure that you are doing properly is enabling USB debugging first but while connected device with PC, a prompt will appear from device screen and then tap on "always allow", then you have to type "adb devices" and follow step by step, if device is recognized you can go to the next step with "adb reboot bootloader" then in fastboot you have to see the bunny otherwise is not properly in fastboot mode, then you can follow with "fastboot devices" and so on, keep in mind that any command will work until device is properly recognized.

Just trying to determine what your words exactly mean when you say "after in fastboot mode it doesn't boot in adb mode." ... without entering in more technical insights adb works when device is on, no sense to boot to fastboot to try to boot to adb after that (?)
If you can boot to fastboot what you have to try firstly is unlock bootloader or be sure that is already unlocked using
Code:
fastboot oem device-info
if your device is or get unlocked then you can try to flash or just boot to a custom recovery but if you can't determine until now if your device is really unlocked then you couldn't go further.
The hardware method to enter to fastboot is from a device off; pressing both pwr and vol down buttons but if the bunny is not displayed probably you didn't really get fastboot mode.

Do yo use WIN10? Find PC with Win7... and install adb/fastboot app and drivers. Than try..
Is your system working now?
Just unlock your bootloader and install OrangeFox recovery than you can flash whatever you need.
Problem solved.

TWRP can't bypass encryption, when you have no access to read data (0mb) then you have to format it, to avoid that is always recommended use OrangeFox, just for future reference, if you understand that you can flash OrangeFox through TWRP for better experience.
Also you can use this tool to help you to automate some stuff https://github.com/Szaki/XiaomiADBFastbootTools
I'm attempting to follow this guide here https://forum.xda-developers.com/t/how-to-unlock-the-t-mobile-bootloader.4256319/ and I'm finding myself having issues at step #5. ADB picks up my device while it's on no issue but when I reboot into bootloader, it no longer picks up my device to get the unlock code.
Anyone know what the issue could be? Any help is appreciated.

Tried in another computer with Windows 10. It returns: "Slot change is not allowed in Lock State"
I get the a code with the fastboot devices, so it seems the phone is ready.
