Hi,

My Nexus5X recently suffered the BLOD issue (which I have had for 3 years, so no warranty for me). I have been chasing various threads here and blogs posts trying to fix it.

I have tried what has been recommended here:
- flash-all.bat (of the Nov 2018 factory image from google)
- reboot, but BLOD
- reboot into fastboot mode
- fastboot flash boot boot-fixed.img (with boot-fixed.img downloaded from the link in the first post in this thread for Nov 2018 images)
- fastboot flash recovery recovery-fixed.img (with recovery-fixed.img downloaded from the link in the first post in this thread for Nov 2018 images)
- wipe cache
The BLOD goes away, but unfortunately the phone doesn't boot past the boot animation (I waited 8 hours). I did the same with the March 2018 files as well, and same result.

I have also tried using the Unblod tool (see "[TOOL] Unblod - Fix your Nexus 5X that's in the bootloop-of-death thread)", using the Nov 2018 stock boot.img).
(starting from stock images)
- adb sideload bullhead-ota-opm7.181105.004-1520cb0b.zip (I also tried flash-all.bat from the factory files)
- run unblod on boot.img
- fastboot flash boot boot-4-cores.img (I also tried flashing from the tool as well)
The BLOD goes away, and the device finishes booting!, but (as happened to many others) the wifi doesn't work, so it's not ideal.

I'd guess comparing what was done between the boot image from this thread and the Unblod boot image, might reveal something important about why neither works as well as it could.

I also tried flashing TWRP and ElementaryX kernel (both from the "Nexus 5X bootloop of death fix (BLOD) | 7/30 Huge performance update!" thread), but that didn't even fix the BLOD issue.

Any suggestions would be appreciated.

You propably have more broken cores than the 2.

November update worked for me and March update was at least reported to work.

Hello,
I used these tools to fix october and november boot images:
  1. AIK - to unpack and repack boot image (images are accessible here: https://www.dropbox.com/sh/b9ggb8ndoenrqpa/AACi6bpLbq8k23-ay2pC2ri1a?dl=0)
    https://forum.xda-developers.com/showthread.php?t=2073775
  2. Github of @XCnathan32
    https://github.com/xcnathan32/4Core-Android-O-5X

If you are stucked on boot logo is there possibility that you have another problem or as @T1mb3 wrote you have corrupted more cores. You can try step by step instructions from this post:

I'm getting a boot loop on with the November update + fix, but I went back to the September update + fix, and it works fine.

I've tried both sets of files. I actually didn't realize at first, but after the first loop, it boots into recovery and says that System is corrupt, and asks to factory reset. After factory resetting, it continues to loop

Factory reset overrides fixed boot image with factory one. Could you please describe procedure of updating to november?

Nov update USB issue.

Used files to update image, then applied fix and then recovery. Phone booted up as expected and seems as though all is fine.

Needed to download some photos and it seems that my Win10 system is not recognizing the N5X any longer.
Rebooted everything 2x, changed ports and cables and still not recognizing my phone.
Also tried a different computer with no results.
Battery indicator does show charging when plugged into computer.
Any ideas or suggestions?

So using the unpackimg.bat and repackimg.bat that came with Unblod (saved me having to figure out Android Kitchen), I've been experimenting with changes to the ramdisk, using xcnathan32 github page as a reference.

To ensure I was starting from scratch I did a flash-all.bat from the factory image (and confirmed BLOD was present). I then unpacked the stock boot.img, and made the same changes to boot.img-cmdline and init.bullhead.rc from xcnathan32's github page, however I did not make any changes to fstab.bullhead (as when I unpacked the Unblod boot.img it didn't have this change). I repacked the files and flashed the new boot.img.

My phone no longer got stuck on the boot animation and successfully booted to the OS. I was extremely happy, until I noticed the wifi wasn't working. And that is where I am at, a Nexus 5X with no wifi, which is not ideal. This was the same result I had using the Unblod tool directly.

Has anyone who has suffered the wifi not working, managed to get it working?

I used the commands from Method 2 in this post https://forum.xda-developers.com/nexus-5x/general/tutorial-flash-factory-images-unroot-t3231627/
At first I just replaced the stock boot and recovery files with the fixed files, but then I also tried flashing stock boot + recovery first and then fixed, but still get the "system corrupt" screen

Update to this issue.
Used September files in same manner and USB issue is resolved. Not sure what is is with my N5X. Tried November files a second time and still had USB problems so I am sticking with September update for now.

Is LG still taking returns on these phones?

I contacted Google on this phone in January when this issue began as some people suggested there was some assistance being offered. Since the phone was out of warranty there was not help and their advice was to return to LG for PAID repair.

The original point to this thread is to rather get a device booted for data recovery - not to make it 100% stable/usable again. I see that people do use this to "fix" their device, but the fact is that this does not fix anything else but the rom, by disabling broken features.
Only real fix is to replace the cpu. It's a shame that the Nexus' life had to end this way, but maybe we can see a better option with a mid-range Pixel.

I will continue providing support as best as I can.

As a person that has been using his "fixed" Nexus for nearly a year, I want to express my thanks for the effort to all that contribute to the BLOD recovery effort. I realize the phone is not as good as new but is so much better, even degraded, than a non working one, I'm happy. Not having the latest/greatest is just part of my being retired. :good:

    [EOL] Nexus 5X Bootloop of Death (BLOD) - Andorid Oreo Monthly Security patches & fix

    Warning:
    DO NOT TRY TO APPLY ANY MODIFICATION HERE IF YOUR PHONE ISN'T A BOOTLOOPING DEVICE.

    Read first:
    This thread is based on the following thread & If you are new to the bootloop issue, please refer the below thread by @XCnathan32 to get your device fixed.
    Nexus 5X bootloop of death fix (BLOD) | 7/30 Huge performance update! By @XCnathan32

    What this thread is about?
    This thread is about BLOD fixes for monthly security updates (Probably OTA). I decided to start a separate thread for these updates since there are no BLOD fixes uploaded for update releases of the Oreo

    Disclaimer
    I do NOT hold any responsibility for bricking devices or any other harm on your devices by using my content since this work isn't based on any kind of monetization. Just to be simple, I do build these images for my device and just sharing with you all since everyone doesn't have the ability to build these images their-own. Each of the files I have uploaded here are tested on my device before posting (only partly, I don't have the time to test all functionality as bullhead is not my daily driver).

    General pre-conditions (Pre-Requirements)
    1. General knowledge about using fastboot & adb
    2. A booltoop fixed device (with an unlocked bootloader/OEM unlocking enabled), as per the original thread by @XCnathan32
    3. fastboot & adb installed on the system (Windows platform preferred)
    4. Downloaded files of your choice for the fix
    5. Refer the pre-conditions in each update for more requirements

    Guides/Downloads
    Please refer the 1st post of this thread

    Information
    - Please let me know if you are unclear about anything regarding the process, steps or files. I will try to optimize the guide to make it user friendly with the time.
    - Let me know if the provided links are not functioning. (I'm looking for a reliable hosting platform to upload future files)
    - Please be kind-enough to share the knowledge with the community if you find any easy methods, workarounds or any other tricks while doing the process.

    Good luck guys. :)

    Step by step process to install the monthly security updates and BLOD fix

    Current URL for updates
    https://forum.xda-developers.com/nexus-5x/general/nexus-5x-bootloop-death-blod-andorid-t3683926

    To do monthly security patch updates, visit the top of the current URL. Download 3 required files: System Image .zip, boot .img file, and recovery .img file. Unzip the system image zip file. Copy the folder with all these files locally to your ADB folder.

    Navigate within extracted zip file folder to find flash-all.bat file and edit. Find "fastboot -w update" line and delete -w so phone is not wiped on update. Only skip this step if you do want the phone to be wiped on update.

    Boot phone into bootloader mode by pressing and holding volume down and power button from powered off state. From command prompt window, run flash-all.bat file to install update. Once done, the phone will bootloop again.

    Boot phone into bootloader mode again by pressing and holding volume down and power button. Flash updated boot .img by running command with current boot .img file name, example:
    fastboot flash boot boot-4Core-bullhead-opm3.171019.013.img

    Optional, flash updated recovery .img by running command with current recovery .img file name, example:

    Boot phone normal using Start onscreen option.

    Thank you T1mb3 for the continued monthly fixes!

    Thanks to this thread and others I managed to fix my bootlooping 5x, which is now working fine again. However I have had the automatic update notification for a couple of weeks now, prompting me to update to 8.1.0 which I understand I can't do without going back to bootlooping again.

    I'm struggling to understand what I need to do now to get this update installed manually, and I'm hoping someone can explain steps by steps?

    TWRP 3.2.0-0:
    [Removed] I've seen multiple complaints in other places that there are issues with 3.2 on the 5x right now. I haven't done enough testing to see it for myself, but i'd rather avoid spreading a file that will cause people issues.

    I tried modifying the latest elementalX Kernel also, but I can't get it to boot.

    Changes are the same as were made here:

    Also, make sure that you are flashing all of the new images when updating. 8.1 includes a new bootloader, radio, vendor.img, system.img, boot.img, and recovery.img.

    Hi,

    I have created a small Python script to automate the process of modifying the boot image to reduce the chance of human mistakes and also make it easier to apply the same fix to future versions.

    Feel free to use, take, modify, etc.
