I have AICP rom 8.1 and BLOD <.<, can I flash only the modified boot image and the modified recovery to get my phone working or I need to flash the entire factory image first? (and lose my data)

---------- Post added at 06:39 PM ---------- Previous post was at 06:18 PM ----------

I tried a temp boot with the modified boot image, I passed google logo but I'm stuck at AICP bootanimation
[Nexus 5X General] albysprx:
I flashed the modified recovery and from it flashed AICP with the modified bootimage inside) but no success, I'm still at the AICP bootanimation, is the EX modified kernel still needed? any solution?
[Nexus 5X General] :
I don't know about that specific rom but generally, if the rom uses stock-ish ramdisk, it should be fine (as long as it's based on the same build). Did you clear the cache?
[Nexus 5X General] :
EX is never actually needed and I don't think it is supported currenlty.

You can flash all the files manually or edit the script to have AOSP without wiping
[Nexus 5X General] albysprx:
Thanks for the answer, anyway I got it working with flashing the factory image and then the modifed boot Image, before the flash I saved my data with the modified recovey with my PC..

Thanks for this fix, you saved my Nexus :)

Anyway can I flash custom ROMs? Or I need to modify the boot Image of the rom by myself? Thanks
[Nexus 5X General] :
It's a matter of trial and error.

If you want to make sure it works, you must see if the rom has stock kernel (and ramdisk). But then it wouldn't be too much more trouble to edit the necessary files
[Nexus 5X General] payas0:
Just wanted to share. Could save N5X lives.

Turns out I'm not affected by the BLOD. I just had a faulty battery. replaced the battery, now everything works fine. No reboots on stock or LOS+EX. But I get random reboots with FK. I no longer have to use the 4core fix.
[Nexus 5X General] Suren Manukyan:
Flashed the March Oreo image, modified boot and recovery on my 5X. At first, when the original image flash completed and it should've started a bootloop it actually started the phone on the "Hi there" screen but it froze immediately and restarted. So i booted to fastboot mode and flashed the modified boot and recovery. Now it's spinning the boot animation for about 25 minutes, i restarted several times but nothing changes. What can i do ?

---------- Post added at 08:42 PM ---------- Previous post was at 07:45 PM ----------

After doing a factory reset for 2 times i was able to get to the setup screen again, but it froze in the middle of the setup and restarted. Now it doesn't go past the "Google", it wont show the boot animation. :( :(

EDIT: Here's the strange thing, flashing the march oreo image itself with Nexus root Toolkit boots up the phone perfectly fine. Running a CPU-z shows all cores working (sometimes the big ones are stopped). Just to make sure i once again flashed the modified boot image and it was still spinning the boot animation forever. Then I Pulled out the original boot from the march oreo package, flashed it and everything is working again. Im still getting random freezes and reboots, i think using only 4 cores can fix it too but i cant boot my phone using 4 core boot file.
[Nexus 5X General] jardinjuiz:
stuck at booting animation

Hi

I have tried to install a factory image, flash modified boot img then flash modified recovery, wipe cache in recovery mode.

After that, 5x can skip white google, but stuck at boot animation(4 different colored circles)

I have tried march and dec oreo factory image, all gave same result.

Any one has any idea what is happening? How can I fix it?
[Nexus 5X General] Suren Manukyan:
Try osm0sis injector fix
[Nexus 5X General] jardinjuiz:
Thanks for your reply. I have tried it but not working.

It's very funny though, I saved my friend's 5x with 4core boot img from this thread, but cant do the same thing for my phone:crying:

[Nexus 5X General] theogene7:
Hi, I tried Jamury 8.1, it worked , but after one month boot problem came back. And now December, January, February, March all don't work in my Nexus 5x. Any help would be very useful.

Thanks.
[Nexus 5X General] jardinjuiz:
:highfive::highfive: great proposal
[Nexus 5X General] :
Maybe try the older images?
[Nexus 5X General] Dr Genki's:
I have to download and install the 4core-androidboot.img every time I receive the monthly security patch? ?
[Nexus 5X General] Suren Manukyan:
Okay I have saved my 5X with osm0sis's injector but I have two things to say

1. Can anyone tell me what exactly does that injector do?

2.My phone starts to bootloop when it reaches temperatures of near 32-33C, it makes the phone unusable from late spring to mid fall. Is there something I can do with it?
[Nexus 5X General] _Ghost:
[MENTION=4524516]truekasun[/MENTION] could you post the same 4 core fix for the stock boot.img of ABC rom or one of a custom kernel ? The one posted on the BLOD thread is causing bootloops for me whenever I flash it over Oreo custom roms. Thank You;
[Nexus 5X General] truekasun:
Before flashing a custom rom, find the version of the oreo release and flash the respective boot.img from the original post. Then you'll have no problem.

Ex:

ROM: [ROM] [ BULLHEAD ] AICP 13.0 | Oreo 8.0.0 | OFFICIAL NIGHTLIES by semdoc

Version: OPR4.170623.006

That means you have to flash the boot.img of September release.

FYI:

OPR6.170623.013, Aug 2017

OPR4.170623.006, Sep 2017

OPR4.170623.009, Oct 2017
[Nexus 5X General] joenun:
I have tried a few ROMs, even with the correct boot flashed none will get past system boot animation. They all eventually restart to TWRP
[Nexus 5X General] truekasun:
I'm unable to provide boot.img for all roms our there for Nexus 5x. Instead you can build your own images if you go through the source code and github. That's not a big deal to modify the boot.img ;)
[Nexus 5X General] joenun:
it's just that the original BSOD thread says "you may be able to use almost any rom with a stock based kernel, just flash the EX zip over it."

that statement is false. thanks anyways
[Nexus 5X General] truekasun:
I see his statement and yeah, maybe it's wrong but I never tried the EX kernel on my device. If you need that really bad, just uploaded the needed boot.img here. I'll rebuild it for the 4cores for you. :)
[Nexus 5X General] Sofiane omega:
bro can you make 1core recovery and 1core boot for android O October update
[Nexus 5X General] BigDomTheFirst:
Good evening,

I have just flashed the latest boot.img to the correct version of Oreo, and it seems to be taking ages to boot up. I've been waiting for twenty minutes now. I've double checked the right image for the right android version, and it all fits but no boot :( I bought the device as a spares and repairs device with a bootloop problem, cut could it just be an easier software problem?...

Thanks, Dom
[Nexus 5X General] truekasun:
I can create a single core version but I wont test it on my device so all you'll get is a untested boot.img is that OK with you? I cannot grantee if that works. Let me know if it works so I will continue to add single core version from the next release.

These images are build to use the first core of the your CPU.

But, why?

Can you tell me, in short, why this problem is happening, my gf's phone bootlooped but was under warrant and they fixed it somehow, i just wanna know, bc its happening to so many people, does this mean it will happen again? And do you recommend taking some steps such as installing this on the phone, to try and prevent this issue in the near future
[Nexus 5X General] mhdsanto85:
Is there a 4 core boot for 8.1 DP?
[Nexus 5X General] GTX90:
my nexus 5x updated to oreo with october patches got loot today, still in warranty but can't use as stockisti.com is gone (fraud)... do you think is a good idea try that fix? phone is looping from like 4h...
[Nexus 5X General] cell2011:
API change to 27 for 8.1. We just have to wait for a new 4 core
[Nexus 5X General] louisli:
I can only go through steps 1-3.

My device is original and not rooted before.

After finishing step 3 (USB cable still connecting), I choose to enter boot loader from the menu. Device restart and goes into Google bootloop, I start the device with fastboot again, then choose "recovery mode", device reboot and there is the screen of dead android with red exclamation, and the words "no command".

So I can't proceed with step 4 and there should be some menu for choose according to your guide.

My device:

-Bootloader version BHZ11M

-Baseband M8994F-2.6.37.2.21
[Nexus 5X General] truekasun:
Original post updated for the new images.

Good luck guys! :)
[Nexus 5X General] truekasun:
When you see the "no command" screen, Hold power button and then press the volume up button. Then you'll see the other options.

:good:
[Nexus 5X General] truekasun:
If you don't have the warranty, the only option you left is trying these fixes. I've got reports that some devices does not fixed with these images too but there is a probability around 90% as my experience on this.
[Nexus 5X General] truekasun:
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.

By [MENTION=5288606]XCnathan32[/MENTION]

--------------------------------

Yes, there are reports that SOME replacement devices from LG (warranty) are also having bootloops lately. But I don't recommend you to flash these fixes on a non-bootlooping device. There are no such a way to prevent this issue before it occurs.
[Nexus 5X General] louisli:
Thank you. I think I tried but what it did was just rebooted and looped.

I finally managed to fix the device (maybe temporary?) through another guide on this forum, as I had my device bricked for 2 days and was so eager to fix it or buy a new unit. Thank you for your guys' contribution.

Do you think it's safe to update to Oreo after this fix? Will it BLOD again?
[Nexus 5X General] truekasun:
Glad to hear that you fixed your device. Of course it's safe to update to Oreo since the process if familiar with you already. :good:
[Nexus 5X General] adilau:

I can download the update from the phone (OTA) or I have to download the factory image from Google deployers page To install 4core-Android.img?
[Nexus 5X General] :
It does not matter how you get the updated system but you must flash the modified boot to get it working again.
[Nexus 5X General] :
Coming in an hour. I didn't realize it was already released:cyclops:
[Nexus 5X General] :
I don't have time to edit the op right now but here are the files, tested and working: https://mega.nz/#F!9LpHAI7L!-VbDObUxcQhQnwNQ6FLNeA

Note: I could not boot it if it was not factory resetted.

[Nexus 5X General] bahill:
Wait, so we have to do a factory reset for this month's patch?
[Nexus 5X General] :
You can try.

People have had the infinite boot issue for a long time so maybe that's the real issue.

Use backups if you need a new patch every month :p
[Nexus 5X General] Kristjan Bandur:
Please make a 4 core version for 8.1.0 (OPM3.171019.014, Feb 2018)

I just flashed it...no problems, no need to factory reset. I did flash the radio as well, as I see that changed...just fyi.

Thanks again for keeping this updated!
[Nexus 5X General] :
Ok!

I see you didn't use flash-all script. Maybe that's the issue then
[Nexus 5X General] bochi:
I got the same problem. And this way I fix it ! (but phone must be with unlocked OEM build (Settings->System->About Phone - on Build Number click 7 times to enable Developer Options - than in Settings -> System->Developer Options - OEM Unlocking - On)

(if phone want to boot to anything - Shut it down and put it on cold place for 15 minute, or shut it down with battery on full and wait "some" hours (24 or 48) !

If phone want to switch on - try upper or open it and disconnect battery and reconect - on my LG 5X this is easy back cover + 10 screws and main plate :))

[Nexus 5X General] vitsdroid:
thanks for this forum I was able to resurrect my nexus 5x with it after lg declined the warranty. LG said it was irreparable, and that the device had water damage even though it did not. Sucks that I didnt try this before sending in my phone to scammy lg and lost $20 in the process. Here is how i got my device to live again.

1. Downloaded sdk, usb drivers, and all required images from the first page of this forum.

2. I could not get powershell to work for me in windows 10, so I opened CMD as admin and navigated to platform-tools folder (downloaded images need to be in "platform-tools" folder)

3. Once there I put the phone into fastboot mode (power button + Down volume)

4. In CMD i entereed command fastboot devices and got the serial number of the phone then I entered the commands below and my device booted like a new phone would. Phone needs to have unlocked bootloader so if it isnt unlock it, its takes 10 seconds. fastboot oem unlock agree and reboot.

fastboot erase boot

fastboot erase cache

fastboot erase recovery

fastboot erase system

fastboot erase userdata

fastboot flash bootloader bootloader-bullhead-bhz31b.img

fastboot reboot-bootloader

fastboot flash boot boot-fixed.img

fastboot flash recovery recovery-fixed.img

Hope this helps someone, and thanks for everyone that contributed. You guys/gals are awesome.
[Nexus 5X General] lithium42:
I feel like I'm missing something, and haven't yet been able to successfully boot to system for more than a minute.

ADB, fastboot, drivers, etc. are all set up. Edit: I re-extract the platform-tools and build images into a fresh directory between attempts, do I don't think I'm mismatching images.

Processes:

A) The "step by step" process in T1mb3's second post on this thread, with December, January, and March 8.1 images.

- Get to fastboot with Power+VolumeDown, connect via USB to windows 10

- Extract zip to same directory as fastboot.exe

- open powershell in same directory as fastboot.exe

- .\flash-all.bat (kept -w, already have data backed up)

- Phone reboots into system, passes "Google" splashscreen, and freezes on dots animation

- Get back to fastboot with Power+VolumeDown

- .\fastboot.exe flash boot <boot image from same month/version>

- .\fastboot.exe flash recovery <recovery image from same month/version>

- Enter recovery mode

- Wipe cache partition

- Boot normally to system

At this point I either freeze on the dots animation, during new-phone setup, or soon after actually getting to a home screen. Sometimes it will just sit on the dots animation forever (30+ minutes)

B) osm0sis' injector on a few 8.1 images from December - April

- .\flash-all.bat (kept -w, already have data backed up)

- Phone reboots into system, passes "Google" splashscreen, and freezes on dots animation

- Get back to fastboot with Power+VolumeDown

- flash osm0sis' twrp-*-bullhead.img from basketbuild

- enter TWRP recovery

- ADB sideload "N5X-6P_BLOD_Workaround_Injector_Addon-AK2-signed.zip" from basketbuild

- reboot to system

I see the same behavior as Process-A. I have tried factory-resetting and wiping cache in TWRP before rebooting to system with no luck. If it makes a difference, TWRP reported my CPU temp at around 25C during this process.

C) The step-by-step by vitsdroid

Same stuff.

Am I missing something critical here? I've never had to deal with fastboot or sideloading, so I may very well be skipping something that others assume to be obvious.

Again, I already have all my data backed up. I just want a phone to use for a couple of weeks until I get a new one.

Thanks!
[Nexus 5X General] SlimSnoopOS:
Regarding method B using Osmosis injector zip. Are you installing the injector zip while booted in fbe TWRP? Your post just states that you adb sideload the zip onto the phone. Didn't see where you actually install the zip.

Please also consider that this just may not work on your device. Some people have phones that just will not boot up even with a 4 core boot image installed.
[Nexus 5X General] lithium42:
Thanks for the quick reply!

I boot into TWRP, hit 'Advanced', then 'ADB Sideload'. I then swipe to start, and do not check any of the wipe checkboxes. After swiping, I execute "\.adb.exe sideload N5X-6P_BLOD_Workaround_Injector_Addon-AK2-signed.zip" from powershell. Once I do that I see some output from TWRP mentioning osmosis and patching boot/recovery. Is that correct?
[Nexus 5X General] SlimSnoopOS:
Sounds about right. Unfortunately, it just may not work for you either way
[Nexus 5X General] :
If you can somehow find out if there is more cores broken then I could provide a boot image with even less cores enabled.

I can make a one-core version to try if your cpu is the problem in the first place

[Nexus 5X General] alex_nikkou:
I flashed the "8.1.0 (OPM2.171019.029, Apr 2018)" image on my BLODed 5X, then flashed boot-fixed.img and recovery-fixed.img and thank God this combo seems to work.

However I'm gravely confused about the versioning of TWRP and EX Kernel. I don't see any new versions corresponding to new Android updates of either. Do I need to install "TWRP version 3.1.1" and "EX kernel version 5.03, for Android O" from the original thread? I tried it this way but the phone went bootlooping again which maybe means that they are incompatible with the latest Android version. Which TWRP and EX Kernel should I try to flash if they can work at all for the 4-core April 8.1.0?

Update: I found the latest files here but still don't know where do these 4 core versions come from. Would be neat to have it all in one post here on XDA as well. Just a suggestion though.
[Nexus 5X General] FireFox31:
What happens if I flash these patched images on a Nexus 5X which is not currently experiencing the bootloop? I convinced a friend to get a 5X before I knew about the bootloop and want to protect his phone from ever having the problem.

Thanks T1mb3 for making these patched images. Seems like they are the best way to solve the problem.

[Nexus 5X General] :

[Nexus 5X General] ugly1:
Nops. I didn't. Never had to wipe to install or upgrade.
[Nexus 5X General] alex_swe:
[MENTION=7280252]T1mb3[/MENTION] I suspect the files are switched, by comparing their file sizes with the earlier releases.

Your recovery-fixed.img is actually the boot-4core.img

and your image-new.img is recovery-fixed.img

[MENTION=1819143]ugly1[/MENTION] Can you flip the files and test? Let us know how it goes...
[Nexus 5X General] ugly1:
Yes... :D That's it. It worked without any problem :)

No need to wipe

Thanks :D
[Nexus 5X General] alex_swe:
That's great, glad to hear!!!

Now, you mentioned no need to wipe. I always need to wipe otherwise phone won't boot after the update. I suspect it's something to do with the fact I have Twrp and Magisk installed. Do you happen to install these as well and if so, what would be the step by step to avoid wiping?
[Nexus 5X General] ugly1:
I have a 4-core twrp and magisk also. (need to allways flash it with twrp after).

After the update i allwaus boot in recovery and wipe davlink-cache, Then boot. And allways works

twrp 4 core version: 3.1.1-0 (wich i don't remember where i got it).

Never had to wipe to install the new updates and allways seemed to me a little strange the need to wipe. :eek:
[Nexus 5X General] :
Did that actually happen =). Thank you for that good notice!
