Bricked Pixel C?

Hi all,
I recently picked up a new Pixel and was wanting to flash it. I ended up enabling USB debugging and set OEM unlock within Android settings.
Yet when I use fastboot flashing unlock, it keeps telling me that OEM unlock isn't set. In my haste, I ran flash-all with a new Google build and this overwrote the existing ROM, but left the bootloader intact it seems. Now when I boot, it says I have a damaged OS and I should use recovery. The problem is that even recovery is damaged and it keeps rebooting to the bootloader. So adb won't work either. The only thing that works is fastboot.
Is there anything I can do to fix this or is it completely bricked? I can't seem to use fastboot to flash any ROM to the device - keeps erroring. I tried to match a ROM with the bootloader but that didn't work either.
Any ideas?

I used Nexus Root Toolkit when I got semi-bricked.

Use erase Command on flashboot for data and system then do flash_all again

As was mentioned, if you have fastboot you are ok. You can flash as mentioned above or use this -

NRT is good for people like me who barely know what they're doing, enough to get bricked in the first place like I did. What i like is that it takes away a little of the uncertainty about whether I'm using the right files.
I hadn't rooted and unlocked and done all the setup in about a year so I forgot everything.
Save yourself some trouble and look at the "TWRP bootloops" thread. It's easy to avoid if you follow some specific steps, frustrating otherwise.

Thanks all, but will this even work, given that the bootloader is still locked? I have no way of unlocking it via any fastboot commands. That's why I am completely stuck.
Will NRT do that somehow in a way that fastboot can't? If so, I'll go find a windows machine from somewhere (who still uses Windows!?)

Won't work IF bootloader is still locked. Try this command > fastboot continue
That will work with locked bootloader, but not sure if it'll solve your problem. Nothing to loose by trying...

Yes, you can unlock bootloader from fastboot.
Um...
fastboot oem unlock
Learn fastboot. It's your friend!
btw, you don't need it unlocked to flash the stock image!

Um...no You missed what I wrote in the first post - oem unlock (actually flashing unlock) doesn't work.
So how on earth do i flash the original image - I've tried to do that multiple times and it always fails.

Yeah didn't think NRT would work because of the locked bootloader! Fastboot continue just gets out of fastboot - what is that gonna solve? I have a damaged set of partitions it seems - going from bootloader -> recovery boots back to the bootloader so it's clear that partition is damaged.
Is there any way I can just push some build to rebuild the partitions or can I do absolutely nothing until the bootloader is unlocked. And if so, how on earth can i unlock it if the only thing that works is fastboot?

I'll try that tonight. FWIW, I know I copied the line from flash-all to just flash recovery.img and even the system image, and both failed.
The only difference I see between that and yours is you have '-w update'. Maybe that's the trick.

You don't need that. I actually unlocked mine without it. The tool also has a unlock feature. Its worth a try.

Look for this forum post: flashing to stock android npd90g twrp t3424863
This helped me too. Only difference is I had TWRP installed.
Try unlocking bootloader via termjnal, then use the fastboot command via terminal (pc) fwtool vbnv write dev_boot_fastboot_full_cap 1 to reenable fastboot, then erase the partitions manually as mentioned in the tutorial and reflash them either manually or together using skipsoft / nrt or manual commands and a factory image.
Normally there should not be anything wrong with your bootloader image since modifying it is disabled for bootloader locked devices. Let us know about your progress.
Oh, also never flash an older system image than your current one.

fastboot unlock vs fastboot unlock critical

When I first got my device, everyone was talking about unlocking it with fastboot unlock.... Now I'm seeing several comments that fastboot unlock critical is needed.
Would someone be so kind as to share the difference, and the purpose for each of these?
I ran fastboot unlock back in October, and my device shows "OEM Unlocking" greyed out (bootloader is already unlocked)..
So now I'm wondering if I need to run fastboot unlock critical?
Thanks in advance...

Only if you want to update the bootloader. That's the only thing I can see that critical does.

I believe unlock_critical is necessary if you want to be able to flash updates manually..

"For Pixel 2 XL only: the critical partitions may also need to be unlocked before flashing. The unlock can be performed with this command, and should NOT be done on other devices:
fastboot flashing unlock_critical
If you are updating an older device, run this command:
fastboot oem unlock "
Above quote is from Google Factory Image page.

thanks for the responses.
Since I already ran fastboot unlock, can I just run fastboot unlock_critical? Or do I need to do anything additional prior to running critical?
I've read @nathanchance 's guide where it says run one or the other, but haven't seen anything about running unlock prior to critical.
Thanks again!

You can just run it again. However, it WILL wipe your phone. Which is why I did mine back to back when I got the device. :good:

I ran the basic fastboot unlock when i first got the phone before i knew about the unlock_critical, so I went back recently to run the fastboot unlock critical and it would fail each time telling me the boot loader was already unlocked, even after i went and re-locked it just to run this command. Very interested to know if you can get it to work if you've already previously unlocked your bootloader because i had no luck

This is why I asked the question. I wasn't sure if doing the basic unlock prior to the critical unlock would be an issue.

I've unlocked the ordinary bootloader first, then the bootloader_critical without any problems :good:

I got a replacement Pixel 2 XL and wanted to do unlock_critical from the outset. So, I enabled oem unlock, booted to bootloader, ran the command, the phone prompted me to unlock, which I did. I rebooted and it wiped my data. I thought I was all set. So, I setup my phone. I then went to root with Magisk and it told me I wasn't unlocked. I booted back into OS and it also showed that the bootloader wasn't unlocked. It's definitely a Google version (not Verizon). I rebooted into bootloader and ran the regular fastboot flashing unlock command and it wiped and rebooted to an unlocked bootloader. SO... what happened the first time? Has anyone seen this? Confused, I searched around online and found this link:
https://android.gadgethacks.com/how-to/unlock-bootloader-your-pixel-2-pixel-2-xl-0180707/
It says that when you send the fastboot flashing unlock_critical, you *also* need to send the fastboot flashing unlock command when you are prompted to confirm the unlock on the phone. Did anyone else have to do this? The instructions on XDA do not indicate this step and I don't see comments that others' phones still showed as locked when only using the unlock_critical command.
I tried booting into bootloader to run the unlock_critical command again and it says my bootloader is already unlocked, but there's no indication whether I have critical unlock or regular. I know I could lock it again and try to enter the instructions as provided on that site. However, I'd prefer not to reset my phone again.
Thoughts?

The bootloader_critical unlock has to be performed only if you want to flash the bootloader (e.g. when you flash a factory image), but, if you want to perform all the other operations, such as rooting, kernel flashing, etc., you have to unlock the ordinary bootloader, too.
So, these are the two Fastboot commands:
fastboot flashing unlock_critical (for bootloader flashing, you've already performed this)
fastboot flashing unlock (for all the other operations)
The request which appears on your phone, when you enter these two commands, is the same, and you have to allow the bootloader unlock in both cases :good:

failed remote: flashing is not allowed for critical partitions

Hi,
Apparently, I'm misunderstanding something. I'm trying to root my 2XL. I have unlocked the phone successfully, I believe. I have the notification screen at bootup. When I get to the task of flashing a factory image, I get the Failed notification, "FAILED (remote: Flashing is not allowed for Critical Partitions)". This occurs after ... writing 'bootloader_b'.
I was able to get Magisk installed but only 14.0 and I don't have root.
I haven't rooted anything in over 5 years so most of this stuff is pretty foreign.
Any advice would be welcome.

Unlock critical first then flash 8.1. Make a backup because this will wipe user data.

I am already unlocked and flashed 8.0 manually. I went to flash 8.1 today and got the OPs error. Are you saying that fastboot flashing unlock_critical will also wipe data? Damn that sucks if true.

Without details from you, we can't help you. For example, are you on the latest update? What else did you try? What worked for you and what didn't? Seriously, we can't read your mind. We can't see your phone. We can't perform miracles. It's a bit tiresome to have to ask you for things you should have already provided so we CAN help you.
Since you haven't given any details for anyone to go on, all I can tell you is that depending on the version of Android you are running, the "unlock critical" command may no longer be required, in which case you will get a message when executing the command.

I did not notice this was the forum dedicated to Pixel devices, sorry. I re-did my message in the Oneplus Nord dedicated forum regarding my issue that, however, seems to be the same as the one people encountered here.

You'll need to read about your own phone. This thread is about the Pixel 2 XL. Different manufacturers tend to have different ways to unlock the bootloader.
Also, people who follow this thread are unlikely to know about OnePlus. Find a OnePlus-thread to ask for help.

fastboot oem unlock ?

It ask me I've pressed yes after that the massage is came after restart as your device is corrupt it can't be trusted and will not boot
After that it enter to fastboot but not going to recovery mode or system
While type command in fastboot OEM unlock massege come failed

This happens because your bootloader has been unlocked at one time. There is no going back, even if you use "fastboot oem lock" later.
Edit: Just noticed the part about your device will not boot. You need to find the system image and flash it. I read somewhere today that OnePlus just released the system image for 4.7.4.

Can you unlock again?

@op, IMHO the best possible solution will be to flash stock rom image and stock recovery if required but I think when you flash stock image it will also flash stock recovery.

When you turn off the phone and boot it with VOLUME UP plus POWER, this should send you straight away to Fastboot. Try if you can unlock again, otherwise... bad luck - you'll need a restore session with 1+.

After looking into it further, I agree with you. That's what I get for having a bootloader-locked Samsung device for two years. I must be getting rusty!
Yes, the bootloader can be re-locked. There may still be a tamper flag as with previous OnePlus devices. But having a locked bootloader with non-OEM software would likely cause the problem he is describing. So, he needs to flash the factory image from bootloader.

I've requested to 1+support for restore remote session
Support send me file link and l2 will assist me in within 2 days

DO NOT RELOCK BOOTLOADER UNLESS U READ UP FIRST!!!!!, its worth just waiting the few seconds after reboot, then to go and try to relock the bootloader

It's because of custom recovery.

You unlocked bootloader, flashed rom (custom) and relocked bootloader? Never lock your bootloader on a custom rom! Just enter fastboot again flash twrp (manual/force reboot recovery), copy internal storage to pc then wipe/format everything. Format data. Factory reset then flash latest official rom and reboot

Trying to Flash January OTA

I still haven't received the January Security Update, so i tried updating via the OTA. But i get the following error message. When i type adb reboot recovery. Its like my stock recovery is broken because i get a no command error. My phone isnt' recognized in win10 anymore. Anyone else having this issue? My bootloader is unlocked. Not sure why that would matter.

Tried flashing factory image. I can't install because my bootloader doesn't match. Any ideas? I'm wondering if the January update isn't ready for my phone version

It maybe a bad data cable I had the same issue kinda cable must have put out to much power or something next day I tried it and everything worked.
Adb wouldn't work but fastboot commands would sometimes then next day was able to do all the commands to root and install kernal

The boot loader not matching usually means you did not fully unlock it. I would bet you did unlock, but skipped unlock critical. You need the second one to be able to flash the bootloader. Otherwise you can only flash the same bootloader.

Saw this same issue with another user on another thread. First of all, do you have OEM unlocking and USB debugging turned on in developer options?
Did you already run BOTH bootloader unlocking commands?
Since your OTA and factory image flash didn't work, you'll need to go back to the factory image you were on before you started this process.
If your able to get this all accomplished, then you can proceed to the January update. Best of luck :good:

How do I go about fully unlocking the bootloader? My phone came with 8.0. I do recall that after unlocking I got the mo command booting into recovery.

unsuccessful updated to January image. I updated adb and still got the corrupt bootloader message. flashed december image and have a phone again. I guess, I might need to relock the bootloader and then unlock again? my current working bootloader is TMZ12a. The January image is TMZ12b i believe and for some reason its not working.

In fastboot mode type
Fastboot oem device-info
Is unlock critical still locked?
If so, issue the command to unlock it. If that fails, yeah it looks like you will have to do what the other thread suggests and relock it.

I still haven't received the January Security Update, so i tried updating via the OTA. But i get the following error message. When i type adb reboot recovery. Its like my stock recovery is broken because i get a no command error. My phone isnt' recognized in win10 anymore. Anyone else having this issue? My bootloader is unlocked. Not sure why that would matter.

Don't do adb reboot recovery.
Turn it off, hold volume down, press power, and when bootloader screen shows, move volume button to choose Recovery.
When little green Android symbol shows, press Power, then Volume Up for a moment. You're now in Recovery.
Choose Apply Update from ADB, then follow instructions here: https://developers.google.com/android/ota
It will update you without wiping.

Or adb reboot bootloader if you happen to be there but yes most of the time I just hit power to bring up restart then I hold volume down till it loads into bootloader

Download the full factory image. Not just the OTA. Open the flash-all.bat file and look near the end and edit out the -w and save it.
As long as you remove the -w that will flash the whole factory image but save your date, apps and set up.
So after the edit put it back in fastboot mode and run the flash-all.bat file.

Tried the January image & did that. Phone won't boot & I get corrupt message at bootlicker

Have you verified the sha-256 of the image you downloaded to ensure it's not corrupt?
Goto https://developers.google.com/android/images and copy the SHA-256 checksum from the Full Image you downloaded and compare it to the file downloaded here: http://onlinemd5.com/
- Make sure to choose sha-256 on the md5 site. This will rule out if the downloaded image you have is corrupted or not.
