Hi there,
So I just bought a brand new N6.
Did nothing to it, did not unklock the bootloader, di not flash anything.
Just ran it a first time, set my account, donwloaded the 5.1 OTA when proposed to and then it was over.
After the OTA installation my phone displayed a dead android and "Error".
When rebooting my phone, the apps are "optimizing" undefinitely and then the phone will restart.
I tried factory reset from recovery, that did nothing, I mean, the phone will still bootloop endlessly.
My bootloader is not unlocked so I cannot flash my phone..
Is there anything I can do ?
Thank you in advance

Well, since you haven't enabled OEM unlock, there's not much you can do besides RMA at this point.

unfortunately, that might have been your only option. as you need to boot up first, to enable unlocking of your bootloader, to reflash the factory image. and you cant boot up

That's what I thought.
I thought I could use the fix described here http://forum.xda-developers.com/nexus-6/general/fix-fix-qhusbbulk-cm12-t3059518 but my device does not appear as "qhusb_bulk" like specified so I guess its over.
id get the phone refurbished, from google or from motorola, since it wasnt anything that you did, but was the updates fault. btw, that happens, very rarely, but it does happen that updates can cause issues.

Well thank you anyway, looks like I have no other choice than send the device back.
One last question, since my phone won't stop rebooting endlessly is there any way to turn it off ? Long press on power does not do anythng, it will stil restart...
Edit: I found how to turn it off through bootloader.

Sorry to come back on this thread.
So now I have noticed that when in fastboot, if I type "fastboot oem unlock" I'm getting the popup proposing to unlock bootloader.
As I never selected USB debugging nor enabled developper option when my phone was working, I doubt it would work properly.
Would I have any chance to recover my phone if choosing to unlock the bootloader ?

yes! if you can unlock the bootloader, then you can flash the factory image via fastboot while youre in your bootloader. which would fix you not booting

just return it, if you find that you cant recover it after unlocking the bootloader then they wont take it back

grab a factory image, and read directions for flashing a factory image. you want to flash each individual file inside separately, instead of using the flash-all script.

It worked !! IT WORKED !
I love you xda ! really do love you.
Thanks a million.
(Although it's a bit strange that I was able to unlock bootloader without usb debbugging mode enabled no ?)
This is very interesting indeed. To the OP, where did you purchase the device? I find it very peculiar that you were able to issue the OEM unlock command without using the toggle in settings.
Hi - apologies first of all if this is covered elsewhere in the forums.
I purchased a brand new Nexus 6 directly from Motorola this week as they had slashed the price down to just £309 for the 64gb. It arrived Monday. I turned it on, signed into my network etc. it starting updating apps. Then it said that Android 5.1.1. was available so I downloaded it and proceeded to install. About halfway through the installation it crashed. My phone is now stuck on continually booting up and saying 'optimising xxx apps'. After a bit of research, I found that this was a common problem as 5.1.1. was trying to update and some apps were incompatible. So I read many forums and booted into Recovery mode, wiped the cache, wiped data and did a factory reset, but it still won't work.
I called Motorola who told me that they have had many of their Nexus 6s do this and all they could do was to refund me the phone as they now are out of stock.
Further research led me to read about 'flashing' the phone so I downloaded Wugfresh but I cannot get into the phone to enable me to debug. After many hours today I have come to the conclusion that I am never going to be able to use my new phone which I am gutted about.
My question is, is there anyway to flash the phone without enabling debugging because I cannot get into the main menu because all if does is just keep optimizing apps?
Many thanks for reading and any assistance would be greatly appreciated.

No, he can't try, he has his bootloader locked.
OP, this thread is a classic case of why the first thing anyone should do with this device, even if not planning to root or otherwise modify it, is to enable developer options in settings and enable both USB Debugging and OEM Unlocking. Without both enabled there's no way to resolve your problem, and unfortunately you'll need to contact Motorola and arrange a return, since they are out of stock.
Once you get your money back, look on Swappa for a used device. You may be able to get a device that way at a lower price than what Motorola offers.

Thanks for your advice, but I had no idea, probably like so many others who aren't as clued up on Android that USB Debugging even existed. I just bought a phone that I wanted that now is no good to me having never been able to use it because of a bug in 5.1.1. I am returning to Motorola for refund.
Without wanting to raise false hopes, there is a thread in this forum where the OP says he recovered his device even though the bootloader was locked (he was certain of it, he said...), other people replying that this was impossible, and yet they eventually seemed to accept that it might be. My bootloader has been unlocked since day one, and I don't remember if there was an "Allow OEM unlock" option in Settings - the same thread had discussion about Marshmallow not having it. I suppose this N6 is still on Lollipop, so maybe a red herring...
I'll see if I can find the thread for reference, but in the meantime does anyone recognise the thread I mean?
bacon_roll, since I'm vegetarian I shouldn't be helping you but have you tried Wugfresh's option of "Phone is bricked/bootlooping"? I think all it does is to reboot the device into bootloader anyway, but I think this might be worth a go if you haven't already tried it. You did mention that you've booted into recovery, but you don't mention bootloader mode.

You could check in the About Phone menu to see what version you're on.
Both Android 5.x and Android 6.x have an OEM Unlocking toggle in Development Options. I know because I followed my own advice given above in my previous post in order to flash the latest Android 6.0.1 ROM to the device, and then checked Developer Options afterward.

Hi - please get my hopes up, I really want to keep this phone if I can
Without sounding like a complete nerd, what is the difference between recovery and bootloader mode?
When I scroll through the options with both arrows pressed and power button, I have START, RESTART BOOTLOADER, RECOVERY MODE, POWER OFF, FACTORY, BARCODES, BP TOOLS, QCOM & BOOTLOADER LOGS
I have done factory wipe/cache/restart bootloader etc.
How do I boot into bootloader mode please.
Thank you.
Overly simplistic reply here, but it should be enough to answer the question.
The bootloader prepares the system for booting. Once it's done its work it hands off control of the system to Android's kernel. Recovery is a mini operating system used to initiate low level functions such as wiping the on-board storage. The screen you describe I believe is the bootloader interface, hence why you have a "Restart Bootloader" option instead of "Start Bootloader".
You can probably save some serious money by returning and buying off swappa really. I just broke my N6 and couldn't find one in stock but, used swappa to find one around $260 that was only used for 2 weeks.
If you already have Wugfresh's Nexus Root Toolkit installed, use the "Install & test drivers" button to make sure that you have all your drivers installed properly. If all is ok, although I know this won't be popular advice, then start with the "My device is soft-bricked", then try the "Unlock" button and then "Flash stock" button. If the phone is already a paperweight then I don't believe it can possibly do any more harm, and you might even hit it lucky...
If none of this works, grab Motorola's refund offer with both hands...

Ok thank you.
I downloaded and installed Wugfresh, followed all the instructions. It won't work once it goes to flash because it can't see my phone connected. My PC recognises it as Nexus 6 but on the 'bootloader' screen at the bottom, it says Connect USB Data Cable, even though the phone says Battery OK (Charging). I tried to install latest USB drivers but apparently the latest are installed.
I am giving up now as I don't believe I can try anything else. Just strange that Wugfresh won't see the phone, yet my PC does.
Thanks.
Oh well...
You did try the Wugfresh "Test drivers"? It has a really helpful walkthrough on deleting and installing drivers. I'd give it a go before you give up.

Ok I don't often use this phrase because I think it's very over rated but O M G - IT WORKED!!
I followed the driver guide in Wugfresh as you suggested, downloaded the CORRECT drivers, flashed it, unlocked bootloader, enabled usb debugging (just in case ) and then restored it then finally relocked the bootloader. It worked flawlessly and after setting up it is now 6.0.1 with the 1 Jan 2016 security patch applied - OTA.
I can't think you enough for your suggestion and advice, I really appreciate it and glad that I persevered with it.
Have a great weekend.
Thanks.

That is absolutely fantastic news. I'm almost as pleased as you are. Remote assistance across the ether - you can't beat it with a big stick...
But as your attorney I advise you to go back into bootloader, check the connection (fastboot devices) and unlock again (fastboot oem unlock). This will wipe your device, but I reckon in the last 25 minutes you won't have been able to install much.
There are so many threads on this forum where people have been told "You're stuffed" because they have a problem and have a locked bootloader. Just this afternoon in another thread I read, literally in capital letters "DON'T RELOCK YOUR BOOTLOADER" for this very reason - without it you don't have recourse to the recovery tools you may one day need.
(P.S. Another person whose thread I followed also managed to get a result with NRT after all else had failed. I suggested to him that he might like to thank the developer, Doug Cohen/Wugfresh, more tangibly by donating a few dollars, which you can do through Paypal on his website. After all, he just saved your £300 phone... ).
@dahawthorne: I'll have to look into Wugfresh's utility. Not that I need it for anything, but it would be good to have in the unlikely event something goes wrong over here. Meanwhile, bacon_roll should take your advice to heart, because it will save him a lot of trouble in the future.

FFS, it's not a magic wand, people! It can't do anything that fastboot and adb can't. Don't start a religion here instead teaching people to do stuff with their phones, Christ!
Some people were lucky enogh that their phones came with 5.0, and some early 5.0s didn't check yet for the Enable OEM Unlocking switch. You could have typed fastboot OEM unlock and achieved the same.
So I bought this phone from eBay, like many before it. But this time it came with a twist: when I booted the phone, initial setup ran and all wend fine until I got to the register Google account screen.
There, the phone says: "This phone was reset. To continue, sign in with a Google Account that was previously synced on this device".
No matter what account I use, I always get a Toast message saying "Unable to sign in to device due to a unknown error. Please try another account or try to sign in again after 24 hours.".
I'm guessing this is some kind of theft protection where entering a previously synced account "proves" that you're the legit owner. The authorised service here told me that I need some kind of proof that I'm the legit owner and surely enough the eBay seller has issued no invoice containing the phone's IMEI (or any similar document).
Anyway, here I am with this gorgeous phone on my hands which is little more than a brick due to this.
Is there any way I could get it to work again? Returning it will just generate more costs for me and I'd like to avoid that.
I've seen guides on youtube where they managed to bypass this security measure, but both methods I've seen failed for me. I guess the version running on my phone is just too recent and plugged all the holes.
Do I have any way of downgrading the software at least? Note that this is a fully locked phone and I can't even start TWRP from fastboot.
Anything else?
Edit: Now that I'm re-reading this post, it occurred to me that there's very little chance that this phone wouldn't be a stolen one. Had it not been, the seller would easily issue me an invoice.
Leaving this post only because my searching hasn't turned up anything on XDA. Probably also reporting the guy on eBay.

From the Settings / About, what is exact (full) build name/number?
Generally, if you are on Nougat then IMO, rolling back to MM should completely reset your phone.
You cannot flash TWRP without unlocking Bootloader. But that will not help much for resetting Google protection.
Btw, enable Developer's menu, does it allow you to unlock FRP/OEM Unlocking - in that case you will be able to reset all from EMUI recovery.

It is stock recovery. I don't recall the option for factory reset. In fact there's no options at all, save for reboots.
Fastboot says everything is locked as it should be.
Don't know how to downgrade to MM.

Rollback instructions are here
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
But not sure would it allow you to setup.
That is Factory Reset Protection (FRP/OEM Unlocking) - if it was unlocked you would be allowed to reset from recovery.
You can ask seller - maybe he can login to his Google account and remotely remove Google account from the sold phone.
Or you can try DC Unlocker, not sure would it work
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
Well, DC unlocker ultimately worked, but not before buying a wrong package, having to ask tech support, etc, etc. Not to mention the guy really has no patience for people who don't have his level of understanding of the subject. Why does he do it then if he hates the whole thing so much?

Sorry for bothering but I'm interested now - when Bootloader was unlocked (and FRP too), were you just able to pass setup or you needed to do Factory reset from Recovery or how did you get the stock ROM working for you
Final resolution: the seller sent me an invoice. I guess that means that the phone wasn't stolen after all since they can only expect that this will be entered into Huawei databases.

The procedure was thus:
1. unlocker unlocked the FRP
2. phone rebooted into a factory reset (low level) mode - it specifically said "low level"
3. phone booted into normal Android where the FRP protection was no longer active. On screen where it previously demanded a previous Google account it now only demanded A (any) Google account as I'm used to from all the other phones I ever bought.
Sorry old post
Good day all. Long time lurker of these forums, and I am officially throwing in the towel on my amateur attempts to update my P20 Pro (CLT-L29 C636) from Android 8 to something newer. I've managed to soft brick the thing, getting stuck in a boot loop. I can get to fastboot, and I can (sometimes) get it to enter dload mode with an OTG cable and a thumb drive. I messed something up early on in the process and I am completely unable to go any further. Dload gets to 5% then fails every time, with every thumb drive I've used.
I am willing to accept that I just don't have the technical ability to take this journey any further. Being that I live in the US (Western New York), Huawei lists no official repair centers in the states. Are there any trusted 3rd party repair services I could send my phone to and have an expert attempt to repair the software? At this point it's been bootlooping so long the Huawei logo is ghosted onto the AMOLED screen. I would love to have this phone operational again.
Any thoughts I would greatly appreciate it!
Hold Both Vol + Power until Emergency Rescue pops up.
After that, restore Stock, unlock Bootloader, install any android 10/11/12 GSI u want.
Tried that. It's stuck in bootloop and only occasionally responds to boot prompts. On the couple of times it got past dload failed and prompted me with invalid install and offered to boot to Emergency Recovery, it fails to load the recovery dialog and drops back into a boot loop.
I promise, I have been back and forth with attempts on this phone for four months, and if I thought there was any new surface level tip or trick I haven't tried, I would still be searching. I feel like it's at a point where only specialized software or a physical test point, or something else beyond my technical ability will fix this phone.
I do appreciate the suggestion, though.
Unlocked Phone? So it *might* be possible to recover i imagine if u get twrp running, might need some dirty work, but not impossible.
Edith did forget to mention; Can u see ur Phone via adb/fastboot on your PC?

Sorry if I sent the wrong impression. The bootloader is still locked. It is only carrier unlocked.
I can locate it on DC-Unlocker on fastboot but it won't let me load any files to it.
With locked BL is not much hope left i guess. Hisuite Recovery fails too i imagine?

Oh yeah. HiSuite recovery states that this model isn't compatible with eRecovery and to take the phone to a service center.
Hi.
Updated my Pixel5a to latest android 13.
After unlocking bootloader and rooting the the phone with magisk the phone worked ok for a few days.
When suddenly after reboot it got to fastboot mode with failed to load/verify boot images error.
Tried to flash new image but every command I try now I get the "FAILED (remote: 'error getting device locked state Not Ready')" error
To make things worse i cannot switch the phone to recovery or rescue mode it always reboots to fastboot.

Nobody encountered something similar?
First time since for me since I use smartphones(10+ years), a phone gets bricked so easily without a chance to revive it.
Here is your answer brother
Sorry I missed this.
Unfortunately, it looks like your bootloader is corrupted or malfunctioning, and the only way to fix this is by replacing the mainboard. There are special software tools that can perform a low level reflash, but they are not publicly available.
I have the same issue. After a broken screen replacement, my 5a would often freeze and turn off when these two conditions were met: Not connected to power + screen turned on.
I'm not 100% sure if it was connected to the screen replacement, given the problems only started occurring ~2 weeks later.
The phone would only turn on again when connected to power, even when the battery was already at 100%.
Unfortunately, I thought it was a software issue and didn't get it fixed immediately, so after one of the crashes I was greeted by the fastboot screen from the original poster above. Mine looks exactly the same (except for serial numbers etc.).
Current status:
Locked, unrooted, vanilla Android 13. Assume it's the January OTA, but could be December.
Recovery/Rescue modes don't work, I can only get into Fastboot. Selecting recovery will reboot into Fastboot.
Questions:
Is there a way to restore Android and how? Would it require a mainboard replacement like @V0latyle suggested?
Is the user data on the phone lost, or could it be saved in the process (no recent backups)?
What's the best way to back up an unrooted+locked+vanilla Pixel phone (without Google Cloud backup, given that's not E2E encrypted, afaik)?
Thank you!

1. If I was current when the OP happened, I would've suggested powering on with the button combo to try and get into recovery -- Hold the Power and Volume Down; make sure to try and hold it down for as long as more than a minute. If that doesn't work, I might try Android Flash Tool as Noexcusses once suggested, but that usually requires an unlocked bootloader. Still...since it's officially from Google (the phone's maker), it might have some special "magic" that it can pull of, but don't get your hopes up on that...
3. The currently accepted best method is the Swift Backup app, My Backup Pro is an old and good staple, but without root, there's not much it will be able to save. I believe Swift (can) locks it to your Google account and/or you can password protect the backups, but I'm not totally sure if they encrypt it as well as locking it in such manner; I don't believe My Backup Pro does anything like this. There's always adb commands that might be able to save a little bit more, but again, not by much without root access. And I don't think any unrooted backup method bothers to back up the non-system internal storage.
Sorry for your troubles and hopefully you get it all back up and running! And not to be to "scoldy", but it's always a good idea to back things up (I usually do when I manually update the firmware & security updates each month); I know it's a bit harder to remember when it's an update OTA because it's a lot less involved, but it can be a good trigger to remind to...

I agree... I had it on my todo list forever, but I just couldn't find a good way to back it up without root. And I didn't want root, because in the past that has prevented certain apps from working (e.g., some banking apps would see it as a security issue and refuse to start) and it has created trouble with OTAs.
Will look into this "Swift" app then. It's a shame, this is so trivial with iPhones (fully encrypted iTunes backups).

With a locked bootloader, the only thing you can try to do is sideload an OTA, but if you can't get into recovery mode, I'm not sure there's anything you can do - a locked bootloader will reject commands such as boot, which would be useful in this case to live boot a good image...but if the bootloader was unlocked, you'd just be able to reflash /boot anyway
niscy said:

Unfortunately I believe nothing can be done to save it or back it up. If you could get into recovery and sideload an OTA, user data would be preserved, but since you can't get into recovery, that point is moot, because it looks like your only option to get the device working again is to have it repaired, which would most likely involve mainboard replacement and complete loss of all user data (except what was already backed up into the Google cloud)

There is none. Google cloud backup is the best way, but even this can't back up app data, and there is no way to back up app data without root, because of Scoped Storage - no app can access any other app's "private" data without root permissions.

Actually the only thing that is required is that OEM Unlocking be enabled in developer options. If it is not, the Flash Tool won't work.

If you can boot into system, you'd be better off using Google Cloud Storage because at least that would back up device settings. Swift Backup won't do this, and is otherwise only able to access "generic" data - phone logs, texts, external storage, etc.

No, it's just a GUI alternative that only flashes official images. As I mentioned above this only works if OEM unlocking is enabled, or the bootloader is unlocked. A locked bootloader rejects commands like flash, boot, and update, so the flash tool unlocks the bootloader first (if not already unlocked) before proceeding with the flash.

You can only do this with an unlocked bootloader. Even though it's the factory image, as I mentioned a couple times already, the commands necessary to flash the image are rejected by a locked bootloader.
As for wiping data, this only happens if you use the included script without editing out the -w. Some people with unlocked bootloaders prefer to update using the script, they just change it so it doesn't wipe data. I personally prefer updating using the factory image but I do everything manually through fastboot and ADB because I'm stubbornly old fashioned.

Just so you know, there are ways & methods to keep apps from detecting root; I would say (as far as Pixel 2XL, Pixel 5, and Pixel 7's are concerned) about 95% of apps could be made to hide root from; I get Wallet, 3 banking apps, Netflix, Xfinity apps, & certain games which all shouldn't work with a rooted device to work. And, usually, if for some reason hidden detection stops working, it usually is worked on and works again within a short amount of time.

Hey! At least that's something! And hopefully, at least it's not a total loss...could be worse; you might've/could've had to wait while a repair shop completely replaced the motherboard.
If you end up having to wipe the device to recover, consider the worst case scenario where they replace the motherboard...it would mean a wiped device anyway....
Okay guys, thank you for the help so far @V0latyle @simplepinoi177
This is where I'm now:
It only gives me the "wipe" warning when I select the "Lock Bootloader" box, otherwise it directly proceeds to download the image without giving the warning.
How come I'm getting this far while I'm in Fastboot? Am I on the right path?
The image download failed a few times due to supposedly insufficient disk space (a lie). Turns out the problem was Incognito mode, seems that has restrictions that break the flash tool.
But now I'm getting the below instead after the image downloaded. Does that mean that the tool won't work, because my device is locked?
Flash Failed
Fastboot command (flash:bootloader_b) failed: 'error getting device locked state Not Ready'

See if you can get away with not checking "wipe device" or "lock[ing] bootloader"...
It automatically downloads the factory image -- that's why I said you have to have 3-4GB free on your hard drive...
You get that far because the AFT works in fastboot, and you luckily are still able to see fastboot in your device manager & be in fastboot mode...
I'd say you are on the right path....at least a lot more hopeful than replacing your mobo. But if all doesn't work, you may be required to wipe the device and/or lock the bootloader as well...
Seems the next thing I would have to try is re-running the Flash Tool with the "Wipe device" and "Lock bootloader" boxes checked?
Just to confirm, would the motherboard replacement require a user data wipe? If yes, then I guess I have nothing to lose at this point.

Yes, motherboard replacement requires a user data wipe. I'm unsure if the technician either does this just as policy/practice, or if after installing the new mobo, the Android OS requires it...but I imagine it is the latter...
It might be worth a try to check those boxes, but most likely will not work. Your bootloader is already locked, so "lock[ing] bootloader" is kinda redundant and wouldn't be necessary for it to work...
Okay guys, I think I'm officially ****ed. No matter what boxes I check, I get the error mentioned above ("Fastboot command (flash:bootloader_b) failed: 'error getting device locked state Not Ready'").
But even worse, I checked with some repair shop and they told me they won't even do motherboard replacements for out-of-warranty devices (because thieves would often use this service to "refurbish" stolen phones).
So I can't even get the motherboard replaced, unless I do it myself? **** my life.

Is there a uBreakiFix anywhere near you (they are the official repair company for Google)? If not, would it be possible to ship them the unit?

I might try another store; even if you have to ship it to a distant one)...

All the storage lives in the flash devices, which live on the mainboard. A new mainboard would be preloaded with firmware, and would have to be programmed with your IMEI, but it would be like getting a brand new phone - no user data whatsoever.

The bootloader doesn't have to start unlocked; as long as OEM Unlocking is enabled, the Flash Tool will automatically unlock the bootloader and perform the flash. I'm pretty sure this results in a data wipe.

Negative, the Flash Tool is simply a GUI interface for ADB Platform Tools and uses the same commands. Since, as I have explained multiple times, a locked bootloader rejects several commands required to flash the device, OEM Unlocking would have to be enabled at the very least to use the tool, which would then unlock the bootloader so that the commands will work.
The only "Google approved" way to update ALL devices regardless of OEM lock or bootloader lock is via OTA, because either update_engine in Android system, or the recovery kernel, is able to verify the update package. The bootloader is not capable of verifying packages applied externally; it can only compare certain partitions (such as /boot) against reference hashes (vbmeta images), which is why it's designed to reject all flashing and booting commands while locked
To be able to perform a complete factory reflash on a locked bootloader, the bootloader would have to have the ability to analyze and verify the entire update package, and it simply does not have the resources to do this. Bootloader only has three jobs:
Verify boot images
Load boot images
Provide USB interface (and must be unlocked to flash anything)

As I explained, it's because you'd essentially be getting a brand new phone that has never had user data on it. Wiping data on the old mainboard is unnecessary, but most repair centers don't have a way to transfer user data.
@niscy Before you go any further, let's establish where exactly "Square One" is. Please answer these questions:
Are you able to boot into Android system? Is recovery the only thing not working?
What have you tried to get into recovery mode?
When you attempt to boot into recovery, do you see an error message at the bottom of the bootloader screen?
Do you have any particular issue with backing up your data to Google Cloud if that option is possible?

1) Can't get into Android system, just Fastboot.
2) Select recovery from Fastboot mode with the volume keys. I also tried "fastboot reboot recovery" (doesn't seem to work on the 5a). It doesn't make a difference how I get into fastboot (just turning it on vs. voldown + power key combo).
3) Screen just goes black and stays black for 30-60 seconds or so. Then it goes back to the fastboot screen.
4) While setting it up, the explanations in Android suggested that it was not fully end-to-end encrypted. However, I found some articles online that say the opposite. So maybe I just got confused by ambiguous language.

Interesting...I am aware that, for computers, replacing the motherboard doesn't necessarily touch data because that's usually stored on the hard drive. I figure the internal storage on a smartphone might be set up similarly and have it separated in something the same way (i.e. I imagine it's something similar to a microsd internal circuitry), and thus might not be touched simply by replacing the mobo. I wasn't insinuating that the repair centers would wipe old data that they were going to toss anyway; thought it was separate from the mobo and could possibly survive the exchange.
Thanks for clarifying! Also, I posted this here instead of PMing it because it is somewhat useful information that might help someone else understand things better (like me)...but I do apologize for the off-topic...
I just went back and read your first post. Failure to load/verify boot images means there's a dm-verity issue - as I mentioned previously, the bootloader verifies the integrity of the boot image as it's loaded; this prevents things like persistent rootkits. In this case, it's coming up against an error - the hash of the boot image does not match the verification hash in /vbmeta, probably because it somehow got corrupted during the update. With an unlocked bootloader this would be a fairly simple fix - just reflash /boot - but with a locked bootloader, this is pretty much impossible to fix.

Yeah. At this point, I think you're pretty much limited to two options:
Pay for a repair (expensive)
Buy a new device (even more expensive)
I'm sorry there's no better answer. If OEMs like Google (or in this case, Foxconn as the manufacturer) made a point of providing low level flash tools and training to repair stations, then it might be possible to reflash the boot image. But, they don't do this for a litany of reasons, ranging from "it's cheaper to replace than to fix" to "tools like this could be used for major exploits in the wrong hands".

I wasn't insinuating that the repair centers would wipe old data that they were going to toss anyway; thought it was separate from the mobo and could possibly survive the exchange.
Thanks for clarifying! Also, I posted this here instead of PMing it because it is somewhat useful information that might help someone else understand things better (like me)...but I do apologize for the off-topic...

Yeah, mobile mainboards are generally "all in one", with the SoC, modem, and storage all located on the same board. There are sometimes small daughterboards for things like camera modules and microSD/SIM card slots but for the most part everything is on the same board. All flashable storage is located on the same memory devices - this includes the most basic things such as the bootloader itself and the baseband image, as well as the system partitions, and of course the "userspace" data. Imagine if your hard drive was built into your motherboard, and also hosted your BIOS/UEFI.
There is only one more thing I can advise trying, and it will most likely not work: Try to switch back to the A slot. You can do this through fastboot: fastboot --set-active=a
Again, this is not likely to work because I believe the bootloader will reject this command as well.
An interesting note that isn't of much help right now: The whole point of A/B slots (and seamless system updates) is not just being able to update "on the fly" without booting into recovery and waiting 5-10 minutes for an update to finish, but also a "fail safe" so that if an update fails for whatever reason, the system should recycle back to the last working configuration.
Spoiler: It works like this:
Let's assume for the sake of argument you're on slot A, running the January update.
When the February update becomes available, update_engine downloads the update package, extracts it, and writes it to the inactive slot - in this case, slot B.
The bootloader is then commanded to boot slot B on the next reboot
When user reboots device, bootloader marks slot B as active and attempts to boot from that slot. There are a couple of markers here - a slot can be marked active, bootable, and successful.
Once boot proceeds past a certain point, the slot is now marked bootable. Once loaded into Android system, the boot is marked successful.
If for any reason slot B fails to boot, or crashes at a certain point, the device should automatically reboot back to slot A, and upon successful boot of Android, notify the user that the update failed.
I don't know why it failed to do that in this case. Apparently it thought slot B was both bootable and successful, and the failure didn't occur early enough to recycle back to slot A.
