Hoping someone can help me. I had CM 10.1 installed. Decided I wanted to try KTManta kernel. But I can't get my tablet back to a clean 4.2.1 state.
First I tried restoring the nandroid backup I had created via Nexus 10 Toolkit prior to installing CM. Looked like it was doing something, but then went back to the main menu. Tried doing it manually on tablet. CWM couldnt find any files on my tablet via CWM to restore. Tried pushing the files from computer to tablet in the CWM backup directory. CWM didn't like them. They were unzipped. Maybe that's why? Maybe I can try making a tar file next.
So then I went about reverting back to stock, first using Nexus 10 Toolkit. Unrooted, restored stock recovery, relocked bootloader, etc. That all went fine. Got the notice for an OTA update. That's where things stop going fine. No matter what I try, I cannot get it to install. I either get the red exclamation mark android on his back or my tablet just crashes entirely and I have to reflash factory image from fastboot with the toolkit to get it to boot up.
I also tried WugFresh's Nexus Root Toolkit. Not much luck there, can't even flash factory image. When i try to let it auto download it gives me a hash mismatch error. When I try to install it manually, it fails. Gave up, went back to Nexus 10 Toolkit.
I would greatly appreciate any suggestions.
Trying to sideload the 4.2.1 update via stock recovery fails: set_perm: some changes failed. Installation aborted.
cwm still can't see the nandroid i made via nexus 10 toolkit.
heeeelpppp. how the hell do i get 4.2.1 back on my tablet?
NM, got it installed thanks to six_dfx's post here:

so glad i found this! yes his adjusted file worked perfect! thanks for sharing. Need to get a help sticky going for issues like this
If you had a backup 4.2 Factory Image, you may have an older, broken one. Google updated the 4.2 factory image on their site, which should work fine.

Yes you can.
Long story short, rooted the phone, lost the usb c-a cable. Was never an issue, because wifi file transfers are a thing lol. So now, I'm looking to trade my 6p for a note 5, which will be traded off for a Priv shortly after. The owner of the note 5 has requested the 6p to be reverted to stock, or he's going to trade for an iPhone. So, my question is this, are there currently any ways of returning to stock, without fastboot and what not for flashing image files? Doesn't twrp support image file flashing now? Appreciate any help, thanks!

TWRP does support image flashing, but only a few, not all of the images you'd need to flash. The only way for you to return to stock without a PC is if you made a TWRP backup of your stock setup prior to making any changes. You could restore that backup, but that would still leave TWRP recovery installed, but you could flash the stock recovery using TWRP's image flashing feature. Prior to flashing the stock recovery I'd wipe data, and then format userdata to ensure all of your information is completely gone. The only thing left to do then would be to lock the bootloader, this is only possible with fastboot though. Now after saying all that, if you don't actually have a TWRP backup to restore in the first place you won't be able to return to stock without a PC.

Thanks for the info. The guy backed out of the trade, which is fine with me really. I rather like my 6P lol ????
Hi Guys,
I'm Kinda new about making a new thread, so if anything's wrong let me know.
Just last evening my nexus 6p (on Android 7.0 official) got into a boot loop from a normal state. It just boots & right after when the white google logo transforms into 4 round object, it just reboots (it takes about 3-5 secs). I can access the boot loader but was unable to access to recovery from there as that takes it to bootloop again. I've tried flashing it, but since i had already updated to Nougat official version & the official image for 6p is yet to come, i tried with some earlier version of Marshmallow. but that failed as well. can it be that i need to select the right version of factory image as i really do not remember my old marshmallow versions anymore.
It seems i'm out of options right now. :crying:
Any advice guys??
TIA
Found this on Nexus 6p help forum. Haven't tried it though so I'm unable to confirm if it works or not.

@sirluigi, this EXACT thing just happened to me ..
stock nougat, only bootloader unlocked ((( and since I've got no access to recovery and no Nougat image, I don't know what to do next
minicoop7, unfortunately, for that guide I need to go into recovery mode

Have you tried using fastboot to temp boot to recovery?
fastboot boot twrp-3.0.2-1-angler.img
downloading 'boot.img'...
OKAY [ 0.409s]
booting...
OKAY [ 0.680s]
finished. total time: 1.097s

same behavior, nothing but a bootloop
I'm dowloading an official MM image, just to get the stock recovery and see if I can temp boot in it
edit: not possible, I even tried to flash twrp, I tried flashing stock recovery from MTC20F.. tried to temp boot in both, all with no luck and with phone constantly alternating between the "Your device cannot be checked for corruption" screen and the white Google screen with the open lock.

Guys its very simple, flash the stock mtc20f image first. After that boot it, it wont work but don't worry. Onece it bootloops go into bootloader and fastboot flash twrp 3.0.2-0. once thats done boot into twrp recovery. Onece in twrp make a backup of the image you just flashed that don't work. Once thats done mount system in recovery. Once mounted plug phone into computer and open the twrp folder you will see on your internal wich will have the backup that you just made. Transfer an old working backup into that folder that way twrp will recognize that backup. Once the backup is in the folder you shoukd see 2 backups in there, your new one that doesn't boot and your old one that does work wich you just put into the twrp folder. Once done go to restore and restore the backup of the working rom you just put in there, make sure to check off all on restore. Once done reboot system and it should boot. This will only work if you have a backup of an old working rom.

OMG I finally got mine to work
I'll note down the exact steps , most of which may or may not be relevant
1) Flashed MTC20F using TWRP 3.0.2-1
2) Booted into recovery and wiped everything and the partitions
- Add - Booted back into twrp 3.0.2-1 and then swiped to allow modifications
3) Then fastboot flashed TWRP 3.0.2-0
4) Restored my backup ( except recovery)
5) Still got stuck in the google screen.
Now the next parts are a bit weird
6) Booted into TWRP, flashed vendor.img from pure nexus rom
7) wiped everything except internal storage
8) Flashed vendor.img, pure nexus rom and gapps and then flashed vendor.img again
9) Rebooted and it worked
Let me know if it worked for you guys or if you need any more help

Unfortunately, this didn't work for me.
I believe you should be fine with just trying to flash an earlier recovery version using fastboot... if you're trying to save your data and then factory flash MM and then restore your data to the phone, you should be able to use fastboot pull and then copy them back once you've got a working device by simple copy from windows.

Can you elaborate the steps pls? also have you had an earlier back up of your phone which i don't have?
Has anyone been able to get this to work without being able to get into TWRP? I can't get into recovery whether it is a temp boot to it, or fastboot flash either version..
I have compiled a list of the 20+ methods from various users in THIS thread. It's the second post.
Stuck in a bootloop still @tr4nqui1i7y but will try your methods as well... Fingers crossed..
So I do not if this may help anyone who as run into this issue but still may want to retrieve their data before formating their data or factory resetting. While running TWRP 3.0.3 and flashing the latest 7.1.1 files for angler. I would sometimes be able to boot into the recovery like 3/10 tries ( from the bootloader menu). My data was encrypted and it woul freeze constantly when trying to decrypt soo i decided once I finally got it to boot again in the recovery menu(TWRP after hours mind you) I let the phone stay idle for a few mins should the cpu would cool down that my battery percentage would drop around 41% and the tried to decrypt data which went tru successfully. I retrieve what I Could and it froze during a process of a nandroid backup and started bootlooping again. I believe the battery percentage may be linked to the early shutdown issues that many user were reported having and the bootloop of death we are experiencing. Hopefully this info may help someone else.
Device details:
Oneplus 6t (oos: 10.3.5)
Twrp version "3.4.0-2-fajita"
magisk version 21
So back in 2019 when I first got the 6t I immediately installed twrp but soon found out that the main reason I had gotten twrp wasn't even working.
Here are some of my post I made back then about this issue: [Twrp] is twrp backup/restore broken atm? and [Help] Stuck in fast boot- boot loader after restoring twrp backup?
So what I'm asking is has anyone actually used the nandroid /backup feature in twrp and been able to successfully restore a backup to the device? I get stressed out working with my phone now because I cant trust the twrp backup/restore to actually work and I don't want to have to start fresh or brick my device if I can help it (ill do it if it comes to it but I'd really like to avoid it and I've seen the msm downloadtool interface far too many times for my liking in the past working on this issue)
