Hey so I am having a problem unlocking the bootloader.
This is my friends phone and he messed it up bad. What he told me is that he was trying to install a custom ROM on his phone which was already rooted and unlocked. When he went to install it he told me that the ROM locked his bootloader and earased everything on the phone.
When I got the phone it would only boot into fastboot and nothing else. The screen would just be blank.
I have run that color installed and now I get the opo screen when i turn it on and I can also boot into fastboot. I cannot boot into recovery because it is gone I think.
When I try and install the recovery through fastboot I cannot because the bootloader is still locked.
I also tried loading up the custom recovery with the command fastboot boot recovery recovery.img
This doesn't work because I am getting the error "cannot load 'recovery' : Permission denied
I am out of ideas and any help will be greatly appreciated.

I think your friend is giving you dodgy information, flashing a ROM doesn't lock the bootloader. So can you get into recovery at all by using the recovery button combo? Hold power to turn the phone off. Hold volume down, then hold power (so you're holding them together), when you see the OnePlus boot logo let go of power but keep holding volume down until you reach recovery.

I am sure there is something he isn't telling me.
I have tried booting into recovery and I will hold down the button for several minutes but it never boots into recovery.
The phone will only boot into fastboot.

There isn't much you can do then, without recovery and without being able to unlock the bootloader you're pretty much stuck.

Darn. I was hoping there was some other way of unlocking the booloader. I know I can install a recovery if it was only unlocked.

That's right, recovery install requires an unlocked bootloader. It doesn't really fit your situation but this might be worth looking into.

Thanks! But I have already tried it. The second half of it requires that you have an unlocked bootloader to use fastboot.

I have tried to flash back to stock firmware and return the phone to its original locked bootloader state. I have followed this tutorial here: https://forum.xda-developers.com/showpost.php?p=70326674&postcount=23
The phone is now unable to start, I cannot go into fastboot mode, I cannot go into erecovery mode. Even if I press all three buttons (Vol + Vol - Start) it simply does nothing but reboot the phone into the blue boot screen. I'm basically stuck there. Is there anything, anything I can do?
What is your model?

Hi dear friends,
I'm from Brazil (sorry for my bad english), i bought my Pixel, and try to install Beta 8.1, but i don't verify the bootloader status, and this blocked. The phone doesn't turn on anymore, it stuck in google logo, i tried to unlock bootloader but it NOT ALLOWED, i try to install the Stock Rom, but it needs unlocked bootloader. I'm very dissapointed, i don't know what to do now, anyone could help me ? :crying:
PS: Phone don't boot, or anything else, on recovery appears 'no command', on adb/fastboot says 'unlock your bootloader', and when i try to unlock appears 'unlock bootloader is not allowed'

It appears you bricked your phone. Did you unlock the bootloader prior to trying to install the beta 8.1?

On the boot, before install beta, appears the unlock message, to stop the boot. But after install beta, these message dissappear, and i think the bootloader was locked

How did you install beta? Fastboot the beta factory image or enroll in beta program to install that way?

Ok. From there, press power button and volume up button. This should take you to a screen where you can select factory reset. Perform the factory reset.
Also, when in the bootloader, does it show the bootloader and radio (baseband) ID numbers?

First, to be safe, delete your serial number from your post.
Second, the good news is the Baseband and Bootloader are from the beta DP2.
When booted to bootloader, does the device show unlocked status on the last line?
If so, you should be able to fastboot flash the factory image. Do you know how to do this?
If device shows locked status on the last line, you should contact Google to troubleshoot further.
Hope this helps.
Edit: Forgot to ask, Is your phone a Verizon variant or Google variant?

Last line show Bootloader Locked, I tried to flash the factory image, but it's only possible on Unlocked Bootloader.
I use Google Forum to find this awnser, but no one help me.
Google Variant, International Version.

When you get to the 'no command' screen, did you press power button and then the volume up button? Or did you press them both at the same time?
I may not have been clear about the correct method. It should be first, power button, then volume up button.
That should get you to the stock recovery which will allow a factory reset.

Good news....
After reading the news that a new method had been found for Verizon/EE-UK Google Pixel (Sailfish) Phones to unlock the Bootloader - I decided to do so and then proceed to flash Magisk for root and other benefits however as there was recently a new update which was showing as 'Failed to Install'.
Of cause I wanted to update the device so I attempted to re-lock the Bootloader using 'fastboot flashing lock' and proceeding to select Yes from the prompt. Which seemed to be acceptable and worked to lock the Bootloader.
Now my phone is stuck in a crazy boot-loop where by the phone will turn on - flash the Google logo on the white background for a split second then shut itself down and repeat.
Does anybody have any tips for me to recover the phone from this awful state?

Man, when you lock the bootloader you need to make sure you're 100% back on stock without any modifications flashed. Seems to me you tried locking while having magisk flashed.
Try to see if you're able to get into recovery. Get into bootloader menu by pressing power button+volume down and the press volume upp until you get to recovery and then press power button. If you're able to get into recovery then download the full ota image for Google pixel sailfish from here https://developers.google.com/android/ota and then while you're in there should be an option to update using adb. You need to adb sideload the update from your computer to your phone. I know this should work on a non Verizon phone but I hope and assume that is what's needed this time. If you're not able to get into recovery and your bootloader is still locked then you pretty much have a bricked device.

At the minute I've taken it to a Phone shop hoping they will be able to figure a way to get to the recovery menu - baring in mind I had TWRP flashed.
Yeah, It will go to the Bootloader menu but when trying to go into recovery it will just repeat the same process as before where by it will flash the Google splash-screen then restart. Any notes on how to go about hard flashing the image?
have you tried fastboot boot twrp.img? does it bootloop aswell? if so, you might have hard bricked your pixel... last solution is to try flash stock image and then try again with stock recovery / twrp img.

If you can't access stock recovery and your bootloader is locked then your device is pretty much hard bricked unfortunately. Don't think the phone shop would figure it out, they might change the motherboard as a solution if they don't have the right tools to reflash on a deeper level. Hope they figure it out. Please let us know if they managed to fix it. If not then someone else might have some suggestions. I'll try to think of something else.
Try either of these commands to see if you can unlock the bootloader again:
fastboot oem unlock
or
Code:
fastboot flashing unlock
And then try what the post above me suggests.
Hey, did you ever figure out a solution to this? I did the same thing to myself today...
any solution??

You can unlock the bootloader with htc-fastboot if you have a bricked android 7-8.
They patched it on Android 9.
On android 9 your only chance is to reflash it in edl mode. Anyone here who can help me to enter edl mode with my pixel?
My husband's phone deviced to completely shut down. When he tries to use the bootloader, it shows a message about being corrupt and not trusted. Any idea how to fix this?
-Selecting Bootloader, Recovery, Restart and Off all take him back to the same screen about corrupted phone.
Phone will go into FASTBOOT but will not go into RECOVERY mode.

OnePlus 9 for TMobile.
If he's rooted, that means he didn't unlock the bootloader first. This is what causes that and I've done it myself.
I don't know if either of these will work but worth a shot in this order.
Option 1: *FLASH* UNMODIFIED stock boot.img via fastboot flash boot.img (whatever your filename is, or just drag and drop it in the adb cmd window)
2: Use the TMobile MSM tool to revert back to stock. I believe I tried this on the 6t and it didn't fix the issue somehow but in theory it should cause this is how OnePlus's legendary horrid tech support does it.
