Boot loop even after stock recovery! My bacon is cooked! - Nexus 6P Q&A, Help & Troubleshooting

Okay boys Just got this phone like a week ago. Used it to replace my Samsung that was acting up. Convinced my wife I needed it and then proceeded to toy with it.
I unlocked the bootloader, flashed custom recovery (TWRP latest), and rooted (Magisk latest) to stick recovery. I was running full stock 8.1.0 no custom ROM yet I was doing reading before I wan
ted to flash. Got to feeling comfortable so I got everything ready files downloaded USB hooked up and decided to be safe and make one more back up.
So thats what I did, I made a full TWRP backup, every single partition onto an external USB. So I am safe, right? Best to be safe... But that's when I rebooted from TWRP it boot looped.
So now I am currently stuck at boot. I get the warning screen about the unlocked bootloader then "Google" logo boot screen then a black screen and back to the start again. I knew that wasn't right, so I booted into fastboot with Power + Volume Down, cycled to recovery and selected it then... boot loop. No recovery. Hmmm... That's not good. But keep calm... did some research and found a few things. So i did this...

FAQ can be found in post #3!
[SIZE=+1]10. How To Flash The Factory Images (And Return To Stock)[/SIZE]
Prerequisites: unlocked bootloader (section 1).
This section will explain how to return the phone to be like it was when it came out of the box. This will wipe everything from the phone. If you wish to flash the factory images without wiping your personal data from the internal storage please move on to the next section.
Go to Settings/Backup & Reset and perform a factory data reset. This will remove all of your user data from the device (apps, settings, photos, music, etc).
Download the appropriate factory images for your model here.
Unzip the angler-xxxxxx-factory-xxxxxxxx (x's replace variables) into a directory on your PC (for this guide we'll use C:\angler\).
Once unzipped you should have a folder named angler-xxxxxx (x's replace variables). Open it and move the following files to a new directory named C:\angler\images\:
bootloader-angler-angler-xx.xx.img
radio-angler-angler-xx.xx.img
(Please note that radio and bootloader naming changes from build to build so the filenames and below commands will change with them)
Within C:\angler\angler-xxxxxx\ you'll see another zip archive named image-angler-xxxxxx, unzip the contents of that zip into the C:\angler\images\ folder we created before. Now within C:\angler\images\ you should have the following files:
android-info.txt
boot.img
bootloader-angler-angler-xx.xx.img
cache.img (not present on Android 7.1.2 and above)
radio-angler-angler-xx.xx.img
recovery.img
system.img
userdata.img
vendor.img
Boot into the bootloader and connect your phone to your PC via usb cable.
Open a command prompt from within your fastboot folder (navigate to where you have fastboot.exe located on your PC, shift + right click anywhere within that folder, select open command prompt here), enter these commands to flash:
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
(above command is unnecessary on Android 7.1.2 and above)
fastboot flash cache C:\angler\images\cache.img
(above command is unnecessary on Android 7.1.2 and above)
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash vendor C:\angler\images\vendor.img
On 7.1.2 and above you'll also need to boot into TWRP recovery and wipe cache and dalvik cache.
If you wish to you can also relock the bootloader with this command:
Code:
fastboot flashing lock
(This command will wipe all user data from the device)
Important: do not lock the bootloader unless you have first flashed the stock images. Locking the bootloader while you have a custom recovery installed can result in a brick. Please also note that the locking procedure will wipe all user data from the device.
Once all operations are complete you can reboot the device.

and that didnt work either so next I tried this

Like other curious 6P users, I flashed the "full ota" zip to check out Nougat. Then I tried to restore my nandroid for Dirty Unicorns, and apparently TWRP 3.0.2-1 had a fatal flaw that borked the EFS backup. I tried literally everything I could think of, until I saw the process @be_vigilant did to revive his phone. I'm going to be using his process as the base for the guide, as well as linking you to my nandroid that has now helped two other people revive their device.
What you need:
*MMB29P factory image (although MTC20F also worked for someone).
Direct download link: https://dl.google.com/dl/android/aosp/angler-mmb29m-factory-616cf265.zip
*My nandroid backup (its stock MMB29P, decrypted and rooted)
https://www.androidfilehost.com/?fid=24686679545612465
*TWRP recovery image (3.0.2-0 or one of the newer builds that fixed the EFS stuff)
https://dl.twrp.me/angler/
*Android SDK or at least platform-tools (for fastboot, adb, etc)
The Process:
1. Extract the factory image into the location where you have fastboot.exe (mine is C:\Android\sdk\platform-tools)
2. Extract the nandroid backup - doesn't matter where, I'll explain later
3. Make sure you are in bootloader mode, and run flash-all.bat from the factory image
4. Flash TWRP (fastboot flash recovery twrprecovery.img)
5. Boot into TWRP, and make a new nandroid backup. This step is just to create the TWRP backup folder on your device
6. Now go to wipe, advanced wipe, click on each partition one at a time, choose "Repair or Change File System", then select "Repair File System" - do this for dalvik/art, system, data, internal storage, and cache. It may not work for all of them, but its ok.
***you must mount data again in TWRP after doing this, or you will not be able to see anything***
7. Copy & paste my nandroid onto your device in the correct location (sdcard/TWRP/BACKUPS/XXXXXX)
8. Restore my nandroid and try to boot.
9. If it still does not boot at this point, then you need to run these adb commands (while in TWRP) that @bogomil4e kindly reported to wipe the EFS partitions
adb shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst1 bs=16384 -and-
adb shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst2 bs=16384
Now you should be able to boot up and do anything you want again. Please do not mirror my nandroid or take advantage of it - I am making it available only for people to utilize as a way to unbrick their phone!

And that didn't work either. To be clear I left my bootloader unlocked. Each process works as far as flashing all the files via fastboot. But if I try to reboot or boot recovery, stock or custom, I boot loop. I have been looking everywhere and I dont see a solution and was hoping to get some help.
edit: Now I have also tried this... Doesnt seem to be the bootloop of death.

Read First: This method is relatively drastic, and will hurt device performance some. You should only use this as a last resort, if the more basic methods of fixing a soft brick didn't work (e.g, factory reset, flash stock firmware, etc.)​
*Update 8/22: Android O is working with 4 Cores now! Big thank you to @xls654 for finding out how to get Android O to work.
*Petition:
I made a petition for Google to officially release and sign modified boot.imgs, so that people with locked bootloaders can fix their devices too. Check it out here. (I apologize for dumbing it down so much, I wanted to make sure everyone could understand it)
*Changelog:
8/25 - EX kernel for Android O added.
8/22 - Android O DPR6 boot.img and source added.
8/16 - Started making this fix open-source, source code section added in OP. Also uploaded modified Franco and Flash kernel & source.
8/10 - Added PA 7.2.2 and DarkROM boot images.
8/08, 2nd change - Uploaded modified boot.img for firmware 48C.
8/08 - Updated EX kernel to version 4.1.2. This updated zip adds the CPU utilization patch to the init.elemntalx.rc, instead of removing the old init.angler.rc and copying the new init over. That should mean more compatibility with Roms/kernels that modify the init.angler.rc. I also modified the camera-daemon to use cpus 0-3 instead of 0-2, so hopefully this should make the a camera bit faster too.
8/07 - Added boot.img that only uses 1 core. Someone suggested I make a boot.img that only uses 1 core, just to see if it works for devices that didn't work with the 4 Core fix.
7/30 - Added universal EX zip, this zip should modify your kernel to use only 4 cores, and it should modify it to utilize all 4 cores. You can flash this over most ROMs and it should work. Also added a donation url, and this changelog.
7/29, 2nd change - Added Pure Nexus and PA dev version boot images, modified to use 4 cores, and utilize all 4.
7/29 - Updated this fix to greatly improve performance. Before this fix, the device was only using 1 core for foreground tasks, now it will use all 4 cores. Also revamped OP.
7/21 - Fix created, stock boot.img, TWRP image, and EX kernel modified to use 4 cores.
*What this fix does, and how to apply it:
The problem:
The problem with most of the devices in a BLOD, is that a hardware failure related to the BIG cluster has occurred. This fix remedies the problem by disabling the BIG cores. Unfortunately, this does mean that you will take a performance hit. However, I am continually working on ways to improve the device's performance.
The update: If anyone remembers device performance with the first fix, it was hurt a lot, however, after finding out that the device was only using 1 core for all foreground tasks, I modified the ramdisk to utilize all 4 cores more effectively, and it helps a lot.
Requirements: For this fix to work, you need:
A brain
A computer
A bootlooping 6P with an unlocked bootloader/OEM unlocking enabled
The modified files of your choice
Fastboot on your computer (preferably installed system wide). If you do not know what this is, or do not have it, look at this post. Answer yes to all of the prompts to install it.
How to apply the fix:
Boot your phone into bootloader (hold power and volume down).
Connect your phone to the computer.
Go to the folder where you have the modified files, then hold shift and right click in a blank space, click on "open command prompt here" in the menu that pops up.
In the command prompt: type "fastboot flash boot [name of the file here]" and then press enter. If you're flashing TWRP, replace boot with recovery. (Linux users, make sure you're running as root)
Edit: With the new EX zip, you shouldn't need to flash the boot.img anymore, you can just flash twrp, and then flash EX in twrp.
Boot up your phone, and hopefully it should work!
*If your phone is bootloader locked/OEM locked:
You can try to get your phone to boot long enough to enable OEM unlocking. Some users have reported success by freezing their phone for a bit, then booting it. Others have let their battery drain all the way, and then tried to boot their phone, but the most successful method seems to be heating up your phone (a lot).
If you do attempt any of these methods, make sure you have time and patience, as it will take a long time.
To enable OEM unlocking and unlock bootloader:
Go to settings.
Go to developer options, if you do not see that, go to "about phone", scroll to build number, and then tap it 7 times. You should now see developer options in settings.
Once you're in developer options, click on "OEM unlocking" and accept the prompt.
Now reboot your phone to bootloader, connect your phone to the computer, and type "fastboot flashing unlock" Your bootloader should now be unlocked.
*Downloads:
Boot.img from stock 6.17, 8.0 firmware: Download | Mirror. This Image is the from the first official release of Android O, and is modified to use 4 cores. It also disables forced encryption as a bonus. Thank you to @xls654 for figuring out how to get Android O to work.
Boot.img from stock 48C, 7.1.2 firmware: Download | Mirror. This Image is modified to use only 4 cores, and is modified to utilize the 4 cores more effectively. I have had multiple people say that first boot takes a while after flashing this, so just wait about 20 minutes before you declare something is wrong with it.
Boot.img from stock 48B, 7.1.2 firmware: Download |Mirror. This Image is modified to use only 4 cores, and is modified to utilize the 4 cores more effectively. I have had multiple people say that first boot takes a while after flashing this, so just wait about 20 minutes before you declare something is wrong with it.
TWRP version 3.1.1: Download | Mirror. This TWRP image is modified to use only 4 cores.
EX kernel version 5.03: Download | Mirror. EX kernel 5.03 works with android 8.0.0. This zip applies the 4 cores patch, but you will need to flash it over an already modified boot.img to work.
Elemental X kernel version 4.12, universal zip: Download | Mirror. This zip is EX kernel, modified to use only 4 cores. Update: I modified it to apply the CPU utilization patch too, so now this is a universal zip, flash it over almost any ROM, and you should now have the BIG cores disabled fix, and the little core utilization fix.
Flash kernel version 2.5: Download | Mirror. This zip is modified to use only 4 cores, and utilize all 4. Works with android 7.1.2. You can flash this over almost any ROM, including stock, and it should boot again.
Franco kernel r55: Download | Mirror. This zip is modified to use only 4 cores, and utilize all 4. Works with android 7.1.2. You can flash this over almost any ROM, including stock, and it should boot again.
You will most likely not need these images. It will be much easier, and much more universal to flash one of the custom kernel zips above ^^^
PA boot.img from PA version 7.2.2, build 8/10: Download | Mirror. Uses only 4 cores, and has core utilization patch.
PA boot.img from PA version 7.2.1: Download | Mirror. Boot.img from PA dev preview 7.2.1, uses only 4 cores, and is modified to utilize 4 cores more effectively. Flash it after you flash the PA zip, either with fastboot, or TWRP image flash.
Pure Nexus boot.img from Pure Nexus 7/25 build Download | Mirror. This image is modified to use only 4 cores, and it has a tweak to utilize the 4 cores more effectively. Flash it after you flash Pure Nexus, either with fastboot, or TWRP image flash.
DarkROM boot.img from 7/21 build: Download | Mirror. This image is modified to use only 4 cores, and has the utilization patch.
Boot.img modified to use only 1 Core. Some people were reporting that the 4 core images weren't working for them, someone suggested that I make a 1 core version to see if that helps at all. Edit: seems not to help unfortunately. Here it is: Download | Mirror
Unfortunately, I have not been able to get Android O working yet, but I am working on it right now.
If you have a favorite custom ROM or kernel you want to ported over to use 4 cores, let me know, and I'll put it up.

*Tested custom ROMS/kernels
I have used Pure Nexus by flashing the modified EX zip over it, it has notably better performance than the stock ROM, and very good battery life. It's a clean, stable ROM, with plenty of good features that are actually useful.
I have also used Paranoid android dev preview, very good performance, definitely my favorite as of now. Battery life leaves something to be desired, but I have not tried a custom kernel yet. Also, 7.2.1 seemed smoother to me than 7.2.2.
If you have a custom ROM/kernel that worked for you, let me know and I'll put it up here.
*To improve performance slightly:
Flash a custom kernel. I will upload more kernels as I test more, so stay tuned.
Overclock the little cores. It can slightly help offset the lost performance, on my 6P, I have mine overclocked to 1632MHz, and it works perfectly for me. Edit: I actually recommend not overclocking. Many people have reported their Little cores failing, so I would go for longevity on this device, and keep it at stock clocks, or even underclock it. The speed difference you get from overclocking is negligible anyways.
Disable animations in developer options. Seriously, as soon as I found out about this tweak, I've used it on ever single device I've owned, it helps a ton.
Turn resolution down to 1080p. On a small screen, the difference in between 1080p and 1440p is not very noticable. To do this, first get root access, then download a terminal emulator. In the terminal, type "su" and grant it root access, then type "wm size 1080x1920", and finally, change the density "wm density 400". Personally, I like my density at 400, but you can expieriment with it. Lower density=Smaller items and text, Higher density=Bigger items and text. Also @Adithya FRK mentioned that you also want to put density in build.prop so apps display correctly. Change ro.sf.lcd_density=560 to your density, if you changed it.

FAQs
What's the password for TWRP/Why is TWRP asking for a password? - In android 7.0, Google added forced encryption to the data partition. To get around this, click cancel when TWRP asks you for a password, and then factory reset the device. Then you can flash EX kernel/Magisk to disable forced encryption.
Why am I getting an error when I try to flash the images? - Your bootloader is probably not unlocked, try running the command "fastboot flashing unlock", If you get an error there too, then you will have to enable OEM unlocking before you can continue.
It's not working for me, how do I fix it? - My only advice for that is: "Flash the stock firmware for whatever version image you're trying to flash, then reflash the images again" If you're stuck on the boot animation, wait at least 20 minutes before you declare it's not working. If none of that works, chances are your device may have a different problem.
Does EX kernel have the new speed fix? - Yep, you can flash this over just about any ROM, and it should patch it to use only 4 cores, and use them well.
I would like to help as many people as I can, however, I am much more likely to be able to easily help you/reply to your post if you clearly state your problem and the steps you attempted to fix it. I will be much less likely to reply to posts such as "omggg i flashed the image and my phone won't boot helppp" Please read through post first, I did not spend time typing up this OP for no one to read it. If I can see that you read through the OP and have attempted all the steps, then I will be much more willing to help you.
I set up donations on my profile, for those of you who want to donate. I have spent countless hours modifying, flashing, testing, and helping, don't get me wrong, I love doing this and helping y'all out, but donations really keep me motivated to keep going, and donations also will help me fund new equipment and devices that will help further my android development.

Anybody have any insight?

Were you successful at returning to stock?
If not, I'm afraid you're suffering from the bootloop issue :'(

No i was not, but the standard 4 core fix isn't working for me either so I don't know what else to do.

I did something similar. Tried to update to latest may patch from custom rom. No sim found...so tried some radios..nothing. Thought I better get back to full stock. Similar to you tried the individual flashes and then the OTA as a whole. During that process I locked the bootloader. Now I get the yellow screen text says software isn't standard...then google logo...then the red text says os is corupt possibly...then google logo, forever. No loops it seems but just doesn't boot.
Anyone with thoughts?

i am on my 2nd 6p with the same problem after installing twrp. the first one i got operational by sideloading via twrp a factory img. to get the sideload to work i had to go back to android 6, 7 and 8 would not work. right now the google firmware site is not working, it has been out for a few days, so i have not been able to try it on the second 6p.
edit; now that i recall the factory img would not load after installing. i then went back to fastboot recovery and got the distress robot, twrp was of course gone. from there i did a factory reset which got me back to go and the long climb back to oreo.

MOTOACTV ROMs

Rooting and updating your MotoActv is about to get significantly easier! No more waiting games for developers to update their ROMs or tools when Motorola pushes a new OTA; now you can do it yourself! I honestly have not seen these types of files ANYWHERE else, so I had to create these myself (with quite a bit of help from [mbm]). But enough blabbing, here are the files and how to use them:
(Note: all these methods assume we have full fastboot access! -- Which we still have at this point)
- Stock Images:
These are not just mere update.zips that you might be accustomed to elsewhere in Android. Nor are these mere fxzs that you might be accustomed to elsewhere with newer Motorola devices. They are in fact both and more. There are 3 main ways to flash these files onto your device, giving you options based on what OS you run and how comfortable you are flashing files to your device.
1) FXZ:
- Operating System: Windows
- Requires: RSD Lite with FXZ Support
- Instructions: Simply load up the file as any standard fxz (it is very straight-forward)
2) Recovery:
- Operating System: Anything that can mount your device
- Requires: The ability to get into recovery
- Instructions: Place the file on the sdcard, boot into recovery, flash as normal
- Note: Recovery does not wipe your device, it is suggested that you do so before flashing stock images
3) Fastboot:
- Operating System: Windows/Linux/Mac
- Instructions (Windows): Unpack the zip, run flash-all.bat (if it fails, run as administrator)
- Instructions (Linux/Mac): Unpack the zip, run flash-all.sh (it should already have proper permissions)
Miscellaneous Images:
These miscellaneous images are nothing you haven't seen before at this point, but their purposes are new, so they too require explanation.
1) AnyRoot:
AnyRoot is based on koush's AnyKernel in the sense that it unpacks and repacks the boot.img on the fly. However, as the name suggests, AnyKernel is meant for kernels, while AnyRoot, actually roots the device on the fly. This will work on any MotoActv device. It is flashed as a normal update.zip and everything is done in the background so you won't noticed much. However, for ease of access, the stock and rooted boot.img is exported to your sdcard in /sdcard/recovery/. Also note, that if you happen to flash AnyRoot over an already rooted device, nothing will happen as it has built-in error checking.
2) rebootRecovery:
rebootRecovery is another fxz type zip, the same as the stock and rooted images, except it can't be flashed in recovery (would be a little redundant don't you think?). This flashes a specially made misc.img by [mbm] that tells the device to reboot into recovery from boot. This means you can flash AnyRoot on any stock device.
How Tos / FAQs:
Now that you know what the files do, I can explain in short steps how to use these files to get what you want:
1) How to Return the Device to Stock?
- flash a stock image using any of the 3 methods
- you can now update via Motocast if you so wish
2) How to Root a Stock Device?
- update your device via Motocast to the latest version (suggested)
- place AnyRoot on your sdcard
- boot into fastboot, and flash rebootRecovery using either of the 2 methods
- flash AnyRoot in recovery
- reboot
3) How do I update my Rooted Device?
- flash a stock image using any of the 3 methods
- update your device via Motocast to the latest version
- place AnyRoot on your sdcard
- boot into fastboot, and flash rebootRecovery using either of the 2 methods
- flash AnyRoot in recovery
- reboot
Q: After using rebootRecovery I can't get out of recovery!?
A: You are using an old recovery that doesn't clear the 'reboot-recovery' command; use the newer recovery: https://dl.dropbox.com/u/5849675/android/f100/CWMR5x_F100_recoveryB2.img
Q: What do these ROM offer over other custom ROMs?
A: Nothing, they are simply stock images, but you can upgrade with them.
Q: How much battery should I have when I flash?
A: Performing any kind of these flashes will drain at least 10% of your battery, I wouldn't suggest you flash below 60% ESPECIALLY IF YOU FLASH rebootRecovery!
Q: What happens if I flash a 16gb zip on my 8gb or visa-versa?
A: Don't freak, it will still boot, but it's not the best thing in the world to do, just go back and flash the correct model zip.
Q: Can I extract the images from your zips and flash them my own way?
A: yep (couldn't really think of anything else to say)
Q: I manually flashed the stock-boot.img from AnyRoot, and now I can't update. Why?!
A: The boot.imgs need to be truncated before they can be flashed to correctly work with Motorola's updates, just use the stock images.
Q: What's next?
A: HyprActv -- What's this?

I rooted and flashed in recovery (the stock 4.55.97 and the the rooted version 4.55.97) and I stay on 4.55.78 no matter what! The flashes go through successfully... But nothing has changed and the System version still says 4.55.78... But like I said, the flashes both completed! I did a factory reset... and the updater-script wipes system, so what could be my issue?

It sounds like you flashed that old boot.img. Do you have the battery percentage in the status bar? According to TheEndGame7 that is another surefire way to tell if you are on 4.55.97, if you used any of the root tools, it's possible that they automatically flash the old boot.img.

I think I did flash the old boot.img (root tools :O ). I'll try flashing the modified boot img again. Thanks! I had no idea the root tool took me back to the old boot img

Yes, any and all tools that exist so far will need to be updated.
I wiped data / cache and used recovery (b) to install the rooted-4.55.97 zip and didn't have any luck either. I did not use the root tools to flash. Also wiped dalvik cache after and fastboot -w for fun.

Did you end up doing any restore of some kind after you flashed?
Update
There are "new" instructions that might fix the issue where the rooted 4.55.97 appears to not flash. Simply wipe the boot.img image before you flash. And don't use the root tools until they are updated.
Also, if you have success, please post it. Usually "Thanks, it works" is annoying, but in this case where I don't have the device, I need to make sure this is working on some level.
I formated everything from recovery, now I got stuck with Moto logo with no animation when it starts, how to get out of this?

They were pulled, they're not working. There has been some form of mis-communication when I did my testing. I am not working on these until I can get the device from utkanos. Check Update 2, in the initial post.

I was lucky the second time, first time I succeeded to upgrade to rooted 4.55.97 but for some reason I didn't get the battery percentage on the status bar but all other issues are OK and status indicated version number 4.55.97, I repeated flash from recovery but after wiping and remounting all folders, this time for stock 4.55.97
Now I'm on stock 4.55.97 with battery percent on status bar and syncing from my mac.

I went into recovery>mounts, and didn't see any wipe for boot. I took a shot at system since I had already wiped cache and data. Didn't seem to help either. Tried 'fastboot erase boot" and re-flashed. No go. Couldn't start back up the device at all. Tried flashing the latest rooted image using "fastboot flash boot boot.img". No go.
I messed around trying to get the device to boot back up for a while, but it won't even charge right. Only charges long enough to kick off the Motorola 'M', and that is it. On attempts at loading fastboot, I just keep getting an error saying that the battery is low. I know I can only blame myself for this. No fastboot access and no adb access. All attempts at resetting the device have failed.
Before I attempted all of this, my battery was full. Unfortunately, wouldn't charge anymore even plugged into the wall. Any ideas?
Hopefully nobody else makes my mistake.
Man I can't wait till this is perfect, you guys are fricken awesome. I raped your thanks buttons op lol

Will be working on this tonight. I just found out how to make the flash script clear cache and dalvik for you, pre-install. That'll probably save some headache, but it works only in edify format. Not sure what the stock recovery uses...
Anyways, I'm home!

This is a classical case of a corrupt Kernel. Not that the images are corrupt, but somewhere along your update, your boot.img did not install the kernel properly and now you have a broken power manager within kernel.
What I would do is the following:
Hook your watch to the charger and let the M sign show up.
Even if it hangs on the M, leave your watch hooked over night.
Try downloading an older image and use fastboot to erase everything and then flash everything back again. This should return your watch to a working state again.
You may then choose to customize it as you see fit.

I'm about to try this.. but it's making me think... Do you think the updater-script doesn't correctly format system? Think about it... our devices say 4.55.97 (mine changed to that after a reboot or two), and we only had partial features... sounds like something isn't wiping correctly.

Fixed 6P bootlooping, now i want to update to Oreo

Hi all, I posted this in the 6P bootloop thread, but didn't get a response. As that is a pretty LONG thread, i'm thinking my question may have gotten lost in the jumble.
Quick run down.
A few months back my 6P started the BLOD. I found the fix listed on these pages, applied it, and have been happily using my phone ever since. Phone is bone stock 7.1.2 other than the TWRP recovery and the modified EX kernel for 4 cores.
Since the fix, my phone FINALLY got the OTA update to go to Android 8.0 and i obviously want to get it done. My concern is HOW to do this without causing more headache.
Can anyone point me in the right direction? Should i use the OTA update or download the factory image from Google?
I've got some knowledge as i used to be into the "rooting" scene back in the day, but haven't for a while, so i feel a little lost.
Thanks for any help.

Well, for starters do NOT take the OTA. It will either fail or boot loop your phone. Due to the fact you have a modified boot.img you will need to update manually using fastboot with the full image. Re-apply the modified kernel after you finish updating the partitions, but BEFORE booting the first time. You can follow most guides on how to manually update a full image using fastboot, just add the step of flashing the modified kernel before booting.
Thanks for the reply and the help. If i could ask for a little more help, as this is my only phone.
Can you explain the difference between the modified boot.img and the modified kernel?
If i download the factory image from here (https://developers.google.com/android/images) is it ok to the get the latested one (Nov 2017) or do i need to get the original one (Sep 2017 as i'm on Fi)
Once i flash the factory image, is it going to replace the modified boot image as well as the modified kernel?
Follow the OP on this thread (https://forum.xda-developers.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279) in the downloads section there appear to be 2 files i would need, the "Boot.img from stock 6.17, 8.0 firmware" and "EX kernel version 5.03". Am i understanding that correctly?
Like i said, this is my only phone, and i'm probably just being overly paranoid about bricking it, but any clarification would be greatly appreciated.

Use the latest November image. The boot.img contains the kernel and ramdisk, critical files necessary to load the device before the filesystem can be mounted. When you flash the new boot.img contained in the Google image, it will overwrite the patched kernel. You then need to re-patch it by installing EX kernel before booting. EX writes to (modifies) the stock boot.img. There are also pre-modifed boot.img files floating around. You will probably get more detailed help in the dedicated thread. Learning to flash manually (or remember how) is not really a big deal and a necessary skill for modding (and for getting yourself out of trouble). Good luck. :good:

Ok, so 1 last time (sorry)
1 - Downloaded the latest 8.0.0 factory image from google (this contains the bootloader, radio, and partitions (.zip).
2 - Get phone to fastboot and apply the above 3 new images
3- before rebooting, flash oreo4core (new, modified boot.img), TWRP recovery.img
4- reboot to recovery (TWRP) and apply the modified EX kernel
5 - reboot and (hopefully) profit
Am i missing anything, or doing anything that isn't needed?

<<Disclaimer: I don't use the 4 core kernel, so I don't know if it comes with installer script or someone has just modified the latest boot.img>> Unzip the "partitions" zip you refer to and extract those image files to the same folder as bootloader and modem. For example, you can keep TWRP recovery if you don't flash the recovery.img. That is how you preserve your custom recovery. So in other words you'll now have a folder (your ADB folder?) with 5 image files.... bootloader, radio, boot, system, and vendor all in one folder. <<Note: it is my understanding you just substitute the latest oreo4core file (should be boot.img?) If this is true, copy that file into your ADB folder and let it overwrite the stock boot.img. Stop. Copy over flash-all.bat, change the *.bat extension to *.txt and open in notepad. You will see (and can copy/paste) the fastboot commands to get you started with bootloader and radio. Then flash the last 3 (boot, system, vendor). At this point you can reboot into the OS. Since you substituted the oreo4core boot.img file for the stock boot.img there is no need to use TWRP to flash anything. That and since you skipped flashing the recovery.img, TWRP is still there.

Thank for the help! Everything seems to be up and running. I know you said you don't use the "4 cores" (can only assume your either on a different phone or yours isn't affected by the BLOD), but do you know if i still need to apply the EX kernel update, or know of a way to tell if it's already been applied?
Thanks again for all the help. I was pretty much in the right direction, but being as how i'd been away from it for a while, i wanted some backup

I don't think you can flash EX kernel from now on. I think you have to use a modded boot.img that will contain his kernel/ramdisk. This is my guess. You really should be getting your information in the dedicated thread where everyone is actually installing and using it. Google "oreo 4 core" and you will find the XDA thread is the first hit. Good luck. :good:

[How-To] Applying Monthly Security Patches if you're Rooted (Magisk)

So, since once a month I find myself having to click a bunch of links and read how to do a bunch of commands, I wanted to create a thread that (rather generically) explains how to manually flash the OTA monthly updates if you're rooted with Magisk. So, minimally, here's a thread for me to review every month... if it helps you all out, all the better!
Pre-requisites:
Download Latest OTA zip file from Google.
Obtain the STOCK boot.img (required) and dtbo.img (optional) of the System ROM you are currently running. This can be done if you already have the full System Image file downloaded, downloading it currently, or just obtaining the stock boot and dtbo image files elsewhere. (NOTE: This can be skipped if you successfully uninstall Magisk BEFORE you start the process and choose to restore the Stock images in the uninstall process.)
Download Latest Magisk Zip file
Download latest TWRP recovery image
If applicable, have latest USB drivers, adb/fastboot/ files etc.
Preparation:
1) Extract or open the Full Image file and locate the boot.img and dtbo.img files. You will want these on your PC in the platform-tools folder (I usually put the Month name at the beginning, ex. - Jan_boot.img). Again, you can skip if you successfully uninstall Magisk prior to all of this.
2) Copy your OTA zip file to the platform-tools folder, again naming it after the month helps (ex. - Feb_Pixel2XL_OTA.zip)
3) Put your TWRP recovery in platform-tools folder.
4) Place the latest Magisk zip on your Pixel's internal storage (what used to be the SDCard on phones so equipped).
Commands:
1) From PC, open command prompt and change directory to your platform-tools folder.
2) If your phone is on, "adb reboot bootloader" If powered off, press power and Vol Down button to get to Bootloader. Plug your phone into your PC.
3) [If Magisk is not uninstalled first] Command: fastboot flash boot {Name_of_boot.img File}
4) [If Magisk is not uninstalled first] Command: fastboot flash dtbo {Name_of_dtbo.img File}
5) On your phone, hit Vol Down until you see Recovery, then press power button.
6) Once in recovery mode, press power and Vol Up to bring up menu
7) Scroll to item: "Apply update from ADB" and press power
8) Command: adb sideload {Name_of_OTA.zip file}
9) After the OTA finishes flashing, exit recovery back into the Bootloader
10) Command: fastboot boot {twrp_filename.img}
11) Install Magisk Zip file (and any other Zip files you want installed... Kernels, etc.) within TWRP
Then after flashing your zip files, reboot to system and you should be all set.
I believe everything above is correct, but if I've made a glaring mistake, please let me know. I also realize there may be other methods to this madness, but this is what works for me.
With this method do you have to worry about removing your password from your phone before you try to go into twrp?

Thank you for this. Just to be clear in step 2 under prerequisites you say more on this later. Then in step 1 for preparation you prefix your boot and dtbo with Jan xx.img. I get what your saying, but for the newer noobs they may get confused. Maybe reword to say, extract or open the factory image your currently using or the previous months image. Obviously you do this first so that you can sideload the ota. I don't mean any disrespect.
I believe you also need remove the -w from the end of the .bat file after you extract the OTA; otherwise, all of your data will be wiped.
But great job of getting all this info in one place!
So I did this, and now I'm bootlooping. I guess I'll re-flash the Jan factory image and wait a little longer... **UPDATE** I fixed the bootloop by re-trying the process again (after re-verifying the MD5 hash on the update.zip. I rebooted after installing the update,
but before the TWRP flash to install MAGISK. Maybe this allowed the "update"
to finish processing. I also had to remove the pin from my lock screen in order to allow me to get into twrp. After rebooting into the system and removing the pin, I adb reboot bootloader and then flashed twrp. Thanks for the guide!

You don't need to remove the -w from the .bat file since you aren't using it at all to do the update. That is only if you're flashing your factory image.

I mean no disrespect, but this seems awful complicated compared to just flashing the full image with the removed (-w). Especially since your downloading it anyway. I do that then boot the TWRP image and flash the TWRP zip. Reboot into recovery and flash kernel and magisk and reboot system. Again I'm asking for clarity, not dumping on you. Great write up btw!

Well...I can't speak for the OP, but I wrote my extremely similar identical one because, for whatever reason, many users would choose OTAs over flashing full factory images. I/me & you understand the benefits of the factory images over the OTAs; especially understanding the process you must go through to install the OTAs as-of-current is almost the same as flashing the factory images anyways...
But if I were to give a possible explanation to their reasoning is that, like many of them, I come from a non-Google phone (S5 for me), and OTA's were simpler, takes less bandwidth (which still remains true today), they were significantly simpler to install vs. factory images, and with a lot of popular phones you only flash factory images to recover your phone; i.e. muniz_ri's OTA's for the S5 and FlashFire were loads simpler than flashing a whole factory image. But, again, understanding the difference for Pixel 2 and Oreo's OTA & factory images (or the small difference thereof), it's probably better to do a few extra steps and/or downloads to do the whole image than sideloading an OTA.
In the end, this is for people who insist for OTA updates most likely because that's how they are familiar (and therefore more comfortable) with; whether it being explained to them or not...
Cheers!:good:
Fair enough, thanks for the input!

It may seem awful complicated, but to be honest, to me is less complicated than having to edit a script file (which if you forget to do, will lose all of your data). Also, though the steps I wrote out seem like a lot more if you were to write out a process using the full image, it actually works out to be almost the same number of steps.
Lastly, as someone else hinted at, the OTA file size is smaller. The only full image you need is what you are currently running (which in most cases I have on my phone in case the sh__ hits the fan with my phone), not the new full image. (To be even more precise, you only need the boot.img and dtbo.img from the full image file--there may be places to get just those two files out there.)
As I put in the last sentence, I realize there are other methods to this madness, this is basically what works for me. I wanted to get it in writing so I wouldn't forget this down the road, and if it helps anyone here, just icing on the cake. Clearly I'm no Dev and not forcing anyone to perform the updates this way!

Hey bud, wonder I I could pick your brain just a little. When doing monthly Google updates, are most of their proprietary files located in the boot, dtbo, and vendor images?? Your posts have intrigued me a little, and are very well written BTW. My reasoning is this. On my old 6p, about all we needed to do was flash the new vendor, and of course the bootloader and radio if there were any worthwhile improvements. Would the same possibly apply to the P2XL?? I'm just wondering because, now that we're starting to see custom roms, if this would be a viable option, and simplify the updating process. Thank again for your great write up ??

I'll be perfectly honest with you, I haven't taken a dive to see what is in the OTA files and would imagine that it varies depending on the monthly updates.... that said, the only reason why I have stated to re-flash the stock boot.img is because if you are rooted with Magisk, it takes the stock boot.img and modifies it. In order to take an OTA sideload, you need to be on stock boot.img and stock recovery. dtbo is only in my process because there was one time when I tried to sideload and my dtbo wasn't stock (or corrupt). You may not need to flash the stock dtbo.img, but it doesn't hurt to do so.

I'm really happy to see our device has graduated to this level of discussion, instead of the random guessing and 14 different "possible" routes to a solution. Lol
Custom roms abound, once TWRP gets squared away and someone master's the art of turning monthly updates into zip installs we'll pretty much be there!
Btw OP, great write up... Clear and precise!
I do not understand the purpose for downloading the full system image and then flashing only the OTA zip - what am I missing? There is a widely distributed method for performing monthly OTA updates by uninstalling Magisk, updating OTA normally, then flashing Magisk again - seems much simpler, any reason why it would not work?

Downloading the full system image is not required. You only need the Stock versions of boot.img (required) and dtbo.img (optional) of the ROM version your phone is currently running. I actually keep a full system image on my phone in case something goes awry.
I'm going to update the OP to more clearly state that you only need the stock boot.img file--how you obtain it is up to you. Uninstalling Magisk will do the same exact thing, however I tried to do that a couple of months ago and it created more issues for me than if I had just flashed the stock boot.img in the first place.

Downloading the full system image is not required. You only need the Stock versions of boot.img (required) and dtbo.img (optional) of the ROM version your phone is currently running. I actually keep a full system image on my phone in case something goes awry.
I'm going to update the OP to more clearly state that you only need the stock boot.img file--how you obtain it is up to you.

I have not tried the uninstall Magisk method but plan to do so at next update. What kind of issues did it create for you?
Thanks.

For some reason, I don't think it restored the correct (or not corrupted) boot.img version. Then, there were remnants of the Magisk APK and other files so I ended up having to do a full TiBu of my apps and flashed (with wipe) a full System image. It may have been something I did or just my bad luck, but I prefer not to chance it and instead manually flash the Stock image as my "guide" here states.

BLOD 8.1.0 (OPM2.171019.029, Apr 2018) fix

[DEPRECATED] no longer working on due to real life issues. [DEPRECATED]
Please feel free to use my post and work on it yourselves, sorry.
Nexus 5x BLOD fix (OPM2.171019.029)​
I recently purchased a Nexus 5x from ebay; it had the BLOD issue and, after many days I managed to fix it.
So I have decided to update the boot image to the 'latest' android factory image; this will allow people who have applied the patch to use a later version of Android or a custom ROM.
A huge thanks to @XCnathan32 for the original fix!
The steps below will wipe all data from your device!
For Rooting Information and Google Pay fix, see 2nd post.
Changelog
​02/05/2018 - Updated method and added custom ROM method.
​01/05/2018 - Updated TWRP from version 3.1.1.0 to 3.2.1-0.
What does this do?
There are two versions;
The first process will install the 'newest' stock version of Android onto your device; it will then install a custom recovery, and finally flash the updated boot.img file.
The boot.img has been modified slightly to only use 4 out of the 6 cores on the processor, this fixes the overheating issue with the Nexus 5x devices.
The other version is similar except using a custom version of Lineage OS.
Instructions
For detailed instructions and more info please visit the original thread.
Please make sure to have all of the downloaded file ready.
First Method - Stock Image
1. Boot into fastboot mode.
2. Extract factory image zip file and go into its directory.
3. With the phone in fastboot mode and connected the computer, open 'flash-all.bat'.
​3a. Let the process finish; the device will reboot.
4. Go back into fastboot mode.
​4a. [optional] you may wish to flash a custom recovery. If so move into the directory where you have the custom image downloaded. follow step 6a and type in
Code:
fastboot flash recovery [filename].img
5. Now move into the directory in which you downloaded the boot.img file.
6. Once inside; shift-right-click in the file manager and select 'open in powershell' or 'open in cmd'
7. Once the command window has opened: type in
Code:
fastboot flash boot boot.img
8. Now reboot the device!
Second Method - Custom ROM
1. Boot the device into fastboot mode
2. Download the ROM [linked below].
3. Download the GAPPS package [linked below].
4. Download Magisk [linked below].
5. Download the stock factory image; this is important as it contains the newest version of the bootloader, radio and vendor images, which is needed for Lineage to work [linked below].
6. Extract the stock factory image and go into it’s directory.
​6a. There should be a file called ‘flash-all.bat’ - double-click to run it (Make sure phone is plugged in and in fastboot mode!).
​6b. Let the process finish; the device should reboot.
7. Once the device has rebooted, again make sure it’s in fastboot mode.
8. Now download the custom version of TWRP; go into it’s directory then shift-right-click and select ‘open with cmd’ or ‘open with powershell’.
9. Then type the following:
Code:
fastboot flash recovery [filename].img
10. Once that process has finished (it should only take a sec), boot into recovery mode by selecting it via the volume up & down keys; the using the power button to select.
11. Once in recovery;
​11a. Copy and paste the ROM zip archive, Magisk and the GAPPS package to the phone. You should be able to view your phone in the file explorer. If not please install the adb & fastboot drivers.
​11b. Once done; go to ‘Install’ -> the select the zip file you transfered. It will now ask you to confirm, drag the bar across to accept the flash.
12. The ROM will now be flashing; leave it until it is done!
13. Once that process has finished; go back into the install section.
​13a. Now you need to flash the GAPPS package.
14. Once the GAPPS has finished flashing; you now need to flash Magisk. This allows you to root your device and use services like Google Pay.
15. Now reboot!
If all is good then the device will reboot. You should see a boot animation (This can take up to 30 mins, so please wait!), after you should now see the android setup process.

Try following method #1 first, then If you want; flash the custom ROM etc.
The custom ROM I provided works for me so I'm not 100% sure why it's not working. Trying the first method may help :|

Freezing did not worked for me , I put mine the oven and heated it to about 60 Grad Celsius.
That even gave me enough time to back up my data .
however, is back to live because of this tread.
Thanks.
This is the clear and simple instructions that always make things work first try! Thank you so much!
For June 5th security update I managed to work with those instructions, works perfect with making my own 4 core boot image and recovery.

First fix that actually brought my phone back to life
Wow, amazing job, thank you very much! I tried many other methods to fix my device, and some allowed me to boot back into my phone, but I encountered errors like my wifi died etc. So I thought it was the end for my device and it turned into a very expensive USB flash drive lol. I don't know how your fix differs from the other ones on xda ( I used the first method), but it worked for me. So thanks again!
Something happened to my phone today. Its running 8.1 Pixel rom with the bload fix applied. All of a sudden my phone turned off today after running fine from so many months with blod fix. Now it doesn't boot. Google logo and turns off. Not even recovery is working (TWRP 4 core, patched). Can anyone suggest what's wrong?

Good job! Works great for me and my similarly acquired device. Easy to read and follow write up too!
For others who may have done something weird like myself during the flash all process. The only issue I had initially was getting a boot and recovery sig not verified error message (or something like that). Worked around it by extracting the zipped image-bullhead-opm file and copying my fastboot files within the folder then fastboot flashing recovery, system and vendor manually. Then everything per steps explained worked as described. This is probably a common, well known error and fix to the BLOD Nexus 5X owners but I've just had this crazy device 2 days.
Thanks again!
Used 2nd method and worked perfectly.
Phone has been on non-the-less for a solid 3 hours and battery is stable (had really bad battery drain before, and the system was locking up and freezing and unresponsive as well 2-3 weeks before the BLOD.
I had also previously tried to flash a few other newer 8.1 roms after getting this BLOD, however phone crashed several times during installation and returned to BLOD and was unable to return to TWRP/recovery.
Glad the phone is back to life. Thanks a bunch for the modified rom, TWRP link, and guide!
On a side note, do you feel it is safe to try to flash other vendor images + roms + kernels now... or will the device go back to BLOD. From what I understood this is hardware issue, not software? @Dragon's Fedora

Whilst the issue is caused by the hardware; it's actually the software that causes the BLOD. The phone tries to use the 6 cores, but when it detects two of them failing it reboots the device. You can try use other; newer vendor images BUT you must make sure to change the boot.img file within the vendor zip folder.

there is a modified rom that is not stock to boot with the 4 cores, and flashed this boot and the recovery fixed and my nexus is restarted every 5 seconds I would appreciate your help and read many post and I think there is no solution

[TOOL][HOW-TO] [Nexus 5X] Bootloop of Death (BLOD) Workaround [Flashable Zip]

Bootloop of Death (BLOD) Workaround AnyKernel3 zip for Nexus 5X
osm0sis said:
Guys.. bad news.. my Nexus 5X just got hit with the BLOD.
Good news for everyone is I spent a bit of time tonight to first patch TWRP 3.2.1-0-FBE (File-Based Encryption support) image to be 4core, then made an AnyKernel2 zip which will patch the existing boot and recovery partitions on-device to add all the 4core fixes from @XCnathan32.
Should work over any ROM, any custom kernel, recovery, etc., can be added in queue after ROM, root zip + custom kernel to patch it from TWRP or FlashFire (so good for OTAs), and simplifies the initial process greatly since you can now fastboot boot any 4core recovery.img and then adb sideload my AK3 zip to fix the likely newer recovery you already had on your device.

Original thread posts: Nexus 5X, Nexus 6P
Now updated to an AnyKernel3 zip to support the SAR (system-as-root) and 2SI (2 stage init) ROMs that have popped up for Pie and Android 10+!
General Information
If you've found this thread then I'm sure you probably already know what the Bootloop of Death is - separation of the performance (perf) CPU cores - and that the only way to recover from it is to unlock your bootloader and patch to disable the faulty cluster. If you have not enabled unlocking your bootloader yet, the known methods to get it to boot long enough so you can go to System, then Developer Options and toggle "OEM unlocking" are:
super cooling the device in a freezer in a ziplock bag to keep out moisture,
super heating around the camera, and
letting the battery run all the way down before trying to boot.
For further details on these methods check out the original threads by @XCnathan32, linked in the "Thanks" section.
Some important notes before going any further:
Freezing at the Google logo likely points to it being perf cluster separation, but this could also be caused by other components separating.
Freezing at the boot animation suggests ROM/ROM data problem or could also potentially be a BLOD with other components now beginning to separate and that's what people have reported when the 4core mods suddenly stop working with no configuration changes - if you've tried the default boot.img for your ROM, patched with the BLOD AK3 and it still doesn't work, sorry but your device is a brick.
If no 4core recovery boots for you then you definitely have more components than just the performance cores separated, sorry but your device is a brick.
I haven't seen anyone say their devices only worked using a "1core" modification who had tried a proper 4core patched setup; 4core makes sense because it's the separate perf cores cluster becoming unsoldered, but if the 4 low power cores cluster also starts to come unsoldered logically not even a single core would work.. I think that's where the "Green Screen Of Death" comes into it.
DemiGod = Green Screen Of Death; unfortunately this (more components separating given more time - maybe the flash memory chip?) is why many call the 4core workaround only temporary.. there's not much that can be done after that from what I've read.
EX Kernel does not support FBE on these devices because the EX zip patches the fstab forcefdeorfbe flag to encryptable.
Android 10 does not appear to support FBE on these devices but the 4core FBE TWRP build can be used to BLOD patch the latest TWRP (see instructions in next post).
On Oreo, I was personally on stock ROM still, FBE enabled, rooted with SuperSU v2.82 SR5 + suhide and the latest Franco Kernel on my 5X. Then I bumped up the min freq on the low perf cores and it's working great - totally fine for general use, just anything creating a bit of heat like games maxing the low power cores for awhile, or charging, will make it pretty painfully laggy and risk further solder deterioration.
Even though SuperSU development is ostensibly dead, I still strongly recommend it on BLOD-affected devices using stock ROM for reasons I'll explain below.

Update Flashing Instructions
Keep N5X-6P_BLOD_Workaround_Injector_Addon-AK3-signed.zip on your device sdcard, henceforth referred to as BLOD AK3 zip
The correct manual order for a clean flash is: ROM -> root -> custom kernel -> BLOD AK3
Always flash the BLOD AK3 zip last!
Reflashing the BLOD AK3 zip will likely be required after anything that could modify the boot.img or recovery.img, including (but not limited to): ROM updates, custom kernel updates, custom recovery updates.
ROMs:
On custom ROMs with built-in Flash After Update (i.e. OmniROM-based), place your root (if using SuperSU), custom kernel and BLOD AK3 zip in /sdcard/OpenDelta/FlashAfterUpdate/ ensuring the BLOD AK3 is last in the directory listing so that they will be flashed after each update.
On custom ROMs that do not have built-in Flash After Update (i.e. LineageOS-based), you may add my FlashAfterUpdate addon.d script to /system/addon.d/ and then place your root (if using SuperSU), custom kernel and BLOD AK3 zip in /sdcard/FlashAfterUpdate/ ensuring the BLOD AK3 is last for the same effect: flashed after every OTA.
On stock ROM rooted with SuperSU (SuperSU v2.82-SR5 recommended) instead of tapping "Reboot & Install" once the OTA is downloaded you should use @Chainfire's excellent FlashFire app to queue the OTA from /data/ota_package/update_s.zip then queue the SuperSU zip, custom kernel and BLOD AK3 zip, ensuring the BLOD AK3 is last. This is how I have mine set up, since this is by far the most seamless. Be sure to disable EverRoot since SuperSU v2.82-SR5 is newer than the SuperSU included in FlashFire.
On stock ROM rooted with Magisk you must uninstall Magisk from within Magisk Manager to restore your stock boot.img, reboot the ROM to restore your stock recovery partition, tap "Reboot & Install" once the OTA is downloaded, then go through the steps above to flash the 4core TWRP and BLOD AK3 zip again. I definitely recommend SuperSU on this device to avoid the hassle of unrooting and/or messing with factory images.
Kernels:
Custom kernels can be flashed from an app like Franco Kernel Manager & Updater, which can be set to flash without reboot for Franco Kernel updates, or "Flash only" can be chosen in the manual flasher. The FK app supports all types of AnyKernel3 zip so the BLOD AK3 zip may then be flashed after the custom kernel zip to repatch the new kernel's ramdisk.
For other kernel managers that don't support AK3 zips, simply reboot to recovery and flash the BLOD AK3 zip from there to repatch before attempting to boot the ROM again. Also see above under "stock ROM rooted with SuperSU", since FlashFire also works perfectly for this use-case, queuing the custom kernel zip and then the BLOD AK3 zip, with FlashFire's EverRoot option disabled since the device is already rooted.
Recoveries:
Download the updated custom recovery .img and, without flashing it, reboot to recovery, use TWRP's flash image feature to flash the new recovery.img, then without rebooting immediately flash the BLOD AK3 zip to patch it. You can then dump/backup the recovery partition if you want it as a recovery.img. Custom recovery updates can also be done from FlashFire, queuing the BLOD AK3 zip afterward, but the "Preserve recovery" feature must be disabled.
If you prefer to stay on stock recovery for some reason, you can still use TWRP to do the above without flashing TWRP to the device by using "fastboot boot twrp-3.2.1-0-fbe-4core-bullhead.img".

hey,
my nexus 5x unfortunately started having the bootloop issue yesterday.
i tried fixing it using your instructions, now it's stuck in the colored boot animation. it's not frozen, but just stays in the animation forever (i waited already more than 1.5 hrs).
do you have any suggestions what i could try?
thanks in advance!

Does the 4core recovery work? If so, try flashing the lastest factory image, then the BLOD AK2 zip again and see if that helps. If not, you're out of luck.
Hey! Thanks for your instructions, im unbold my nexus 5x! But now my wifi doesn't work. Can it be problem with your img? Bluetooth works by the way.

I don't have an img, I patch whatever's there. What ROM are you using?
Dirty flash your ROM, rename the BLOD AK2 zip to test-debugging.zip, flash and upload the debug.tgz it creates and I'll take a look.
Hey! Thanks for your instructions.
In my the error appears:
adb: sideload connection failed: closed
adb: trying pre-KitKat sideload method...
adb: pre-KitKat sideload connection failed: closed
Do you have a solution?

Are you booted into 4core TWRP? Did you go to the Advanced | ADB Sideload page and swipe to start the sideload mode? Make sure your PC has adb sideload drivers installed? Try a different USB cable? Try adb pushing the file to your device and flashing it from there instead?
Side note to all: BasketBuild is having some down time so I've mirrored the uploads in the OP. :good:
Edit: And BasketBuild is back!
Thanks
So, first of all i would like to tell u that, I thank u a lot for your amazing work, i finally got my nexus 5x out of bootloop after a year
Got to say i thought i would never get it back from there. Also i would like to get some advice:
Currently im running 7.1.2, i wanna download the OTA for oreo, my question is:
As i dont have it rooted, what i should do is download and install it. then make this:
"Reboot your phone to bootloader and connect it to your PC with a USB cable
5) Enter "fastboot flash recovery twrp-3.2.1-0-fbe-4core-bullhead.img" into the cmd prompt
6) Reboot your phone to recovery and tap Advanced, then ADB Sideload
7) Enter "adb sideload N5X-6P_BLOD_Workaround_Injector_Addon-AK2-signed.zip" into the cmd prompt"
Or what do u suggest??
Also it would be better if i get root and then get the OTA? in that case, if i root it should i flash again your patch? or is not necesary.
So Thanks again, for all your work.
FYI the TWRP does matter. I already had TWRP 3.2.1 so I didn't flash the suggested one and it didn't work. Flashing the suggested TWRP worked.
I can't seem to boot into recovery or normally boot(black screen but fastboot mode works fine), with or without the 4core fix (recovery + boot img). Also, to enter fastboot I have to hold power down and volume for a minute or so. Does this mean I'm out of luck?
With stock kernel it doesn't work right? Only custom kernel?
I'm trying to resurrect an old 5X. So i Should:
- fash latest factory image on fastboot
- flash suggested twrp on fastboot
- flash custom kernel, like Franco
- adb sideload in recovery the fix
- reboot and hope ?
Thanks
EDIT: I'm stuck at Google logo, when I reboot to suggested recovery above. It's stuck at Google logo and rebooting also when it is switched off and I plug the wall-charger. Only bootloader mode works! What to do?
EDIT 2: at the end everything works now and boots! Let's see if it stays like this!
Everything worked for couple hours without issues, then it bootloop again. The strange thing is that it doesn't power on anymore after some reboot, tried everything, long press for 10 seconds, 30 seconds, either power only and power + volume buttons.. It switch on only if I disconnect and reconnect the battery by opening the device,it starts but bootloops and then again no sign of life after some bootloops. I remember it happened the same when it died the first time almost 1 year ago I believe. Not even the bootloader come up when it is in this strange state, unless I disconnect the battery.
With the fix I thought it would keep staying alive.. But no luck seems
ok, perfect, everything work....but if I check cpu I see 4 CPU* 1.44GHZ + 2CPU stopped, instead 4 CPU* 1.82GHZ + 2CPU*1.44GHz. Why Did u change frequency of 4 cpu, lowering them?

I didn't and it doesn't.
Oh and as a general FYI to everyone, if I don't respond to your question/post it's because it's already answered in the OPs.
Thank you very much for your work. My phone went into a bootloop today and flashing stock rom didn't work. Your guide was well-written, easy to follow and most importantly worked like a charm!
Hi when i make the 7th point of guide my PC open the zip file.
Which is my error?

It's alive!
Thanks, man. It worked great and was really easy. I will happily make a donation!
Initially my 5X was booting to the Google logo and then rebooting, forever.
I am hoping this will last me until the end of the year when I will get a OP6T or Pixel 3 maybe.
Is there any advice for maintaining the device in this state? For example doing a factory reset, flashing a custom ROM?

Hi! Use some kernel manager to make sure your N5X doesn't turn big cores on, and keep it as cool as possible. Good luck!
