Go over to the rom thread and get the B3 rom and unzip it on your computer and run flash_all.bat/sh

So flashing them will allow you to take an ota? Do you need to flash them to both slots

I've always just used TWRP, but as long as you're not rooted, I don't see why it wouldn't take an OTA.

Can you elaborate on what didn't work?
The thread about factory images of OB 3 contains all the stock image of OB3, in fact, it even restores more files than the one provided on essential website.
It should be the way to go because the script has also been edited so that it restores both partition A and B, making the bootloader locking process more safe
Take any version you wish https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681
but make sure you take full dumps.
By the way, flash-all.bat is for Windows, flash-all.sh is for Mac and Linux

We all know how to use TWRP, I don't know why people are so reluctant to flash the factory zips that way. It's easy as can be.

Because when I updated to 6.0.1 last month, the method changed 3 times before things got worked out. Just want to make sure it is still good to go or if the method changed again in the past 3 weeks.

thats because it was a brand new method for 6.0, it was just developed and bugs were being worked out
Everything's fine for me.
FYI, the radio.img and bootloader.img are the same as MMB29K, so they don't need to be flashed. Boot.img and cache.img are the same size, but I'll flash them anyway. System.img is a different size, so it definitely needs to be flashed.
Looks like the kernel is the same.

While this is true. These security updates are meant to target thing like the root exploits. So while things may still work don't be surprised if it does start needing updates each time Google pushes a security patch. It's a cat and mouse game that will be played until Google manages to lock it down to the point that it is not worth it to root.

The factory image download was very slow. Timed out the first time. Second time it worked OK, but still took about 30 minutes.
Can anyone provide a zip image so that we can flash it in twrp?

Stock w/ systemless root and Elite kernel.
To applying the update I downloaded the factory image from https://developers.google.com/android/nexus/images untar and unzip image-shamu-mmb29s.zip to get at the system.img file. Then did fastboot flash system system.img, just finished booting and and 'upgrading' my apps. It looks like something in boot.img changed too, but everything seems to be running perfectly fine without flashing it; note that I do have a custom kernel installed, so that might have something to do with it.
If you also fastboot flash boot boot.img then you will likely need to go through the root process again to modify the boot.img to allow root to work properly.
Code:
$diff shamu-mmb29k shamu-mmb29s
Binary files shamu-mmb29k/boot.img and shamu-mmb29s/boot.img differ
...
Binary files shamu-mmb29k/recovery.img and shamu-mmb29s/recovery.img differ
Binary files shamu-mmb29k/system.img and shamu-mmb29s/system.img differ
Stock ROM, TWRP
I have followed the instructions and flashed only the system.img..Nexus 6 - Unlocked, Rooted, Stock ROM, TWRP. It appears everything is running well and the Update notification hasn't appeared..this update was constantly appearing in the notification window and was reported as 5.8mb downloaded patch.
Thanks for your help.

Bootloop Help After Trying To Root 7.1.1

So I flashed the 7.1.1 update and everything was fine. I then tried to root through TWRP with the most recent version of recovery and and SuperSu and when I went to reboot it would get to the "Google" splash screen and go back to the warning. I then tried to restore to my Nandroid that I made right before the 7.1.1 flash but it does the same thing. I ended up doing a factory reset, still looping. I tried flashing an old firmware but it still would loop. I got desperate and did a full wipe and then flashed the old firmware from September's update but it still will not boot. I'm a long time lurker I just don't post much. Any help will be appreciated. Thanks in advance!

Have you tried installing custom ROM, instead of a stock one?
And tell us what @ArminasAnarion asked for. There may be a pattern here. :good:
I haven't tried a custom ROM. I'll try that if I get any down time at work. Also, I'll check for you @ArminasAnarion in a bit.
Might be a noob question, but how do I get the custom rom files over to my phone to flash in recovery?

Well if you cant access twrp then your not flashing anything; did you try downloading the latest Nexus 6p factory image and using adb to flash it?? If you need help with that I can lay it out for you. Also there was an efs partition issue with twrp 3.0.2-1 and down so make sure your twrp is 3.0.2-2!

Make sure your using twrp 3.0.2-2; and download the latest factory image for the Nexus 6p (NBD90X) and use adb (fastboot) to flash that whole thing. Extract the files to your android sdk platform tools folder then run the flash-all.bat file. (If you are using a 64gb or 128gb device DONT DO THIS) Only do this with the 32gb model. If its a 64 or 128 model go here -> http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928 and go to sub section 10.

Newest image didn't work either..
Have you tried WugFresh's Nexus Root Toolkit? Not sure if it will work for your situation, but it has an option to restore to factory settings and unroot if you're soft-bricked or bootlooped. Might be worth a shot if everything else isn't working.
FWIW, I successfully updated to 7.1.1 NPF10C and rooted by using fastboot to flash bootloader, radio, boot, system, and vendor. Then used TWRP 3.0.2-2 to flash SuperSU 2.78 SR1. No issues.

Get softbrick with bootloop

Hey guys,
This afternoon I tried to change my file system fo f2fs, I failed and got into bootloop. Follow some instructions, I flash the factory image (I was using stock 7.1.1 Feb and EX Kernel before trying f2fs) but I still face the bootloop. As I know this is a softbrick, because I can still boot into bootloader and flash recovery. But no matter how I try (flash stock, flash rom cook, flash older stock)...my 6P is still in the bootloop. I check in the TWRP that my phone is still in ext4, not f2fs anymore.
I really need some advice to wake him up. Really appreciate your help.
In all honesty bro, I never noticed much difference if any with ext4 vs f2fs. On another note, what kernel and ROM did you flash with f2fs? The the version that supports f2fs gives bootloops when you flash a custom kernel with that recovery. Try flashing the official version of recovery, reboot, then ROM and kernel if you wish and try again.

Why do you still have TWRP if you flashed stock? You need to flash the complete stock image including the stock recovery.

It's a good sign you formatted and received no errors in fastboot. Google provides instructions for flash-all.bat on the same page you download the images from. https://developers.google.com/android/images
If you are not comfortable using the command window in Windows, you could also use a toolkit like Wugfresh's NRT or Skipsoft's Toolkit to automate the whole process.

Hi... Here's a pretty good detailed process on how to unlock/flash, etc...
https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928/page549
Also, before using any toolkit, I suggest using manual commands and getting comfortable with it. At least, you learn exactly what command do what! Simply pressing a button in a program may result in a bricked device. Plus with command line you learn something. :good:

I'm guessing you've already tried a factory reset from the stock recovery. Because your bootloader is locked you are limited to sideloading OTA's. And yes, sideloading an older or equal version OTA will fail. You can try a newer revision OTA when available. The 7.1.2 beta may come out before the March security update.

I agree. Unless you absolutely cannot live without Android Pay or Wallet, work phone, etc., there is no reason to not unlock the bootloader as a safeguard. Of course it's no guarantee, but you just have a whole lot more tools at your disposal when SHTF, including restoring a recent backup or flashing a complete stock image. The initial pain of losing your data can be largely mitigated by pulling it off first, and eventually you even forget about the boot nag screen.

TMO 8T with Global Rom

I am currently on global. Flashed it after being on TMO Stock Rom that was rooted. I followed Crazn's method from this thread, [GUIDE] Convert TMO to Global, EU, or other variant | XDA Developers Forums (xda-developers.com) but extracted my own from the playload bin file. So far no issues at all. I patched the boot.img file using magisk. But remember to flash the non-rooted stock boot.img for the global rom first.. boot it up and then flash the magisk patched boot.img. I tried directly flashing a patched boot.img and it wouldn't boot up all the way.

I'm planning on converting over to the Global Rom today. Couple questions.... I'm not rooting or anything. So I run the flash all.bat from the fastbootd screen pictured in the OP from that thread, or do I select English and let it boot to fastboot? Then I unzip the file in the Fastboot adb tool folder and then enter flashall.bat in the cmnd prompt right? Once it's done flashing can't I just boot into the OS or do I need to reboot and wipe everything?

You don't need to select English.. As long as it says "fastbootd" on the top, you are good to go.
Yes, you can simply run flash_all.bat. Make sure though that you have the latest fastboot.exe (not the one in crazn's upload) in the folder where flash_all.bat and other images are. If not, it'll fail. I believe if you download the conversion folder directly from crazn's upload, he has a version of fastboot there that doesn't work. So make sure you replace it with the latest from google platform tools. Remember to wipe everything by using the recovery menu before booting your phone for the first time after flashing.

I had converted to EU before global was available and I just used Oxygen updater to download global and manually installed it right on the phone.

Made this little project using the script from @mauronofrio FASTBOOT ROMs to return OP8 to latest OOS, since I was always having issues doing so, and always ended up using the unbrick tool for OP8.
Enjoy! If you have any issues, just let me know using a post.
Regards.

I have a T-Mobile device, which I converted to Global and finally installed a custom ROM. For any updates, I have to follow the same route - go back to T-Mobile, then global and then any other ROM. Can I use this utility to go back directly to Global from custom or would I still need to first flash T-Mobile ROM?

Technically, this process would be the same as a conversion. Just see if you need to backup any other extra partition, like persist.img or other.
Regards.
thank you so much for this, ive been stuck or soft bricked for the last 4 days and this might just be my out.
Hi, thanks for this! Now I have a question, I have latest OOS with Magisk, but since upgrade to 11 i have System UI crashes and serious lags and freeze, I did 4 factory resets and its still there, I want to reflash all from 0, can I use this?
Thank you very much for the contribution

There's a self extracting file (*.exe) inside the zip file. Have you run it, and checked the extracted files?

Thanks -- I didn't notice it was an executable. I think I'm ready to go, but just checking. Here's what I've done so far with my T-Mobile version OnePlus 8:
1. completed process to unlock the bootloader (unlocked phone, got token, applied token)
2. set up fastboot in a directory on my Windows PC
3. ran the self-extraction on OnePlus8Oxygen_15.E.35_OTA_0350_all_2103221815-FASTBOOT
Now I'm going to run flash-all.bat. Before I do that, do I need to back up any files, e.g. modem files? Thanks!

backup persist.img and modem.img just in case, and you should be ok to go.
PS: i'm going to upload the fastboot rom without the self extracting method to be easier for users.

@infected_ Considering that I am coming from an unlocked bootloader, will this method re-lock the bootloader and is this carrier-branded compatible?

Safe to use for Verizon OP8 5G UW or is this a method to go Global from a carrier-branded version?

sorry for another simple question; I haven't done system level things with Android in a long time. Where are instructions on how to backup those files? I did a little searching, but haven't found anything that works yet.

Thanks! Now I realize that even though I have an unlocked bootloader, I don't have root access. Now I have to figure out how to get that. Sigh.
And...I see much conflicting information on how to root my bootloader unlocked T-Mobile version OnePlus 8. Any advice/pointers to info on the best/easiest way to root it?
