Is it possible to unlock bootloader without enabling oem unlock in developer options. ( phone is stuck in bootloop).
I can access recovery mode and fastboot.

No mate, you will need to get OEM unlock enabled to flash anything other than a factory ota update. Search pixel bootloop and hopefully you'll find a solution to your issue.
Good luck

If you haven't tried it at all then first try to do a factory reset from recovery. If that doesn't work and if you're on stock and have stock recovery. Download ota: https://developers.google.com/android/ota and see if you can push it to phone using fastboot if you can't access storage of course. And then apply update in recovery. You should be able to boot then.

You could try to erase cache using fastboot and see if it can boot. If not try a factory reset.
If factory reset still doesn't work you'll have to unlock your bootloader, flash a custom recovery and resotre a nanadroid backup or flash a stock rom of 5.0.1.

It doesn't work. How can I unlock boot loader while usb debugging is off. Is there any method?

you don't need usb debugging. Usb debugging is only needed to have adb connectivity when the phone is booted in android.
for gpe device you should be able to unlock it using fastboot from the bootloader.
Code:
fastboot oem unlock
If this method doesnt work you'll need to use HTCdev.com to unlock it.
Don't forget that unlocking your bootloader will wipe everything on your phone.

It have nothing to do with usb debugging! Like I said above, the only purpose of usb debugging is to enable adb connectivity when the phone is booted in android.
Even if usb debugging is turned off, you still have the ability to use fastboot commands from the bootloader (like you have tried) and to use adb commands from a custom recovery (which you don't have access to because of your locked bootloader)
With that said, I'm sorry to tell you that what you are seeing after doing "fastboot oem unlock" (PG_ERROR) is typical of the infamous GPE bootloader bug. This bug make impossible to unlock your bootloader from using oem unlock or by using HTCdev.com method. So your phone is bricked sorry.
you are not alone, see this thread: http://forum.xda-developers.com/showthread.php?t=2547894

Maybe keep it in a drawer and hope that HTC will release a 5.11.1700.3 or higher version official RUU so you'll be able to flash it with s-on and a locked bootloader.
or maybe you could ask the guys at fonefunshop if they are able to s-off it using their method which doesnt require to boot in the rom.
I was installed with Twrp and had rooted my oneplus 3.
I unticked root access in supersu.
Booted to bootloader and typed on my pc in command prompt ,"Fastboot oem lock"
This gave a confirmation on my device,I confirmed locking.
And after that my device did not booted up.I managed to get in bootloader again as I was not even able to open the recovery and unlocked the bootloader once again by this my device booted up.
I flashed stock recovery and repeated the relocking process,this time I was able to open recovery also but no able to boot up.
I again unlocked the bootloader and installed twrp back turned my device up.
Then I unchecked oem unlocking under developer options.
Relocked the bootloader once again.
And now I am stuck at bootloader,not able to unlock it even this time as I turned off oem unlocking.
Now I can only open bootloader.
Please help!

OEM locking a bootloader on a phone that was rooted is a big mistake.
You'll need to flash stock recovery, then flash the stock ROM via adb sideload.
Can be done with this tool http://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
Thanks for reply

I can't access it as I am installed with TWRP Recovery as it is also not starting.
Well I'm having a strange issue.
I've unlocked bootloader then flashed twrp. It didn't work then. When i boot my phone to recovery, a screen appears with a security warning and nothing happens. Then somehow my frp is triggered. Now i can't flash anything and my recovery is messed up . My phone boots normally though.
Is there any way to unlock the FRP? :/
Anyone? ?

In developer options is OEM setting which need be enabled for FRP unlocked. Probably with unlocked bootloader u cant change this option, so need relock bootloader and enable OEM and again unlock bl

I know that brother. I've tried dload method for full firmware restore. Sadly after 5% it shows error . Now I'm left with no options at all.
Hello, I have a vanilla Pixel 2 which corrupted itself and will not boot. It boots to recovery mode, but Bootloader is locked. I have not done a factory reset, and am attempting to recover the files. Fastboot mode works but will not allow temporary boot or unlocking of bootloader. I can access adb but only in sideload mode. OTA images successfully sideload but it still will not boot... After hours of scouring google I'm stumped. Any thoughts or suggestions welcome.
Hint: Add Pixel 2 to this thread's title thus mainly owners of such a phone get addressed.

I see that u want to keep your files but sorry to say this but your gonna have to do a factory reset because their is no other way to fix this
To do this boot into recovery mode and perform a factory reset
If u can't boot into recovery mode u probably have to unlock bootloader than install twrp
But that's probably only gonna work if u enabled oem unlock and enabled usb debugger before your device got bricked
Because if u try to unlock the bootloader with oem unlock and usb debugger disenable your gonna receive error when trying to unlock bootloader
Try to start in recovery mode. Otherwise only restore is the option.
You can start mobile in fastboot mode. You can back up mobile.
adb backup -all

On Android-side bootloader initializes ADB and mounts partitions. Hence check whether phone is accessible via ADB:
Code:
adb reboot
adb devices
If it is, and partitions got mounted, then you can fetch the user-data you are interested in by means of adb pull method.
Hi while upgrading on Android 12 my oneplus device software is uninstalled and no i do not have any installed software and fastboot mode is locked but device is detecting in fastboot.
Is there any way to unlock bootloader or reinstall the software without fastboot?

So when you try to boot, it just goes straight to fastboot right away? If so, and bootloader is locked, you need MSM. You can try fastboot oem unlock command, but if you don't have unlock oem ticked in developer options, I don't think they're is anything else you can to

You installed with MSM in EDL mode? Might have to do it again. Then when it's finished boot to the system and enable developer options then tick oem unlock in the options then go to bootloader and type fastboot oem unlock. You can't install a12 with MSM afaik anyway.
