Hey Interceptor1910. First of all I'd like to add my sincere apologies for such a tardy reply and I know how it feels to get a reply that's about 10 days late! I understand your issue and would like to share a similar situation at my end. My close buddy's Nexus 5X apparently suffers from a similar issue wherein even the bootloader doesn't startup! And leaving the phone as it is for about 6~7H would eventually run it out of battery and turn off. Subsequently when I tried connecting it to the charger to try my luck, turns out it just fires up the red LED that blinks. I tried booting his N5X after a few days when it actually does boot up the bootloader but eventually it comes back to the same "dead" state after a while of staying up. This certainly isn't the big cluster issue but a concrete motherboard failure and sadly Unblod would be able to do no good! :(

I'm really sorry about the technical limitation at hand Interceptor1910. Hoping to hear from you. Sorry again about the late reply!

Thanks.
[Nexus 5X General] theGeekyLad:
Hey monzer! My sincere apologies for the late reply, part of which is because I received no notification from XDA regarding the reply. Was mostly caught up with the semester kick off here in univ and hence couldn't really play around with the kernel much.

Would definitely try taking it up over the weekend with my friend's N5X that's got the big cluster issue, right now running stock 7.1.1 on 4 cores.

Will definitely keep you in the loop! Thanks.
[Nexus 5X General] theGeekyLad:
Hey dinindourden! That's pretty legit. Should take about that long to boot. Was it successful?
[Nexus 5X General] theGeekyLad:
Hey Elancastro! Sorry for the late reply, but I didn't quite get you. I caught what you said about updating your device over an OTA when it kinda ran outta charge, right? Does your phone boot into bootloader? If it does then you're lucky as well as safe. In that case you might just have to pick up the latest factory image and flash it over to your phone following the steps to run Unblod as explained in the OP.

Let me know if you think it works! Thanks.
[Nexus 5X General] theGeekyLad:
Hey smuecke! Sorry for the late reply, but are you on stock 7.1.1 or before? Would be working over this weekend with the WiFi fix. Was a bit caught up with the new sem at my univ. Kindly stay tuned for a post update shortly then! Thanks.
[Nexus 5X General] theGeekyLad:
Hey joenun! Was the prepared with Unblod? Just inquisitive to know if it really works with EX too!

Thanks!
[Nexus 5X General] Interceptor1910:
It's ok, no worries :)

My 5X already RIP in his own box.

Nothing I can do with him so I just bought Xiaomi MI A1 as a temporary or maybe perm phone.

I only regret that my phone died just like that. It looks almost like brand new, no scratches, never doped and than suddenly it frozen and never waken up :(

I hope that your fix will rescue other phones, for mine is already to late :( but tbh this Xiaomi is quite good though :)
[Nexus 5X General] Elancastro:
My English is very bad, I'm sorry.

I was updating my nexus 5X and it was in process when the battery ran out, and I put it to charge right away and it did not turn on anymore, only the red LED shows it. What can I do ???
[Nexus 5X General] dinindourden:
Thanks for the reply. I was able to boot another rom (validus)

However the wifi issue is there with every rom I have tried so far.
[Nexus 5X General] smuecke:
Hi.

I tried it with stock 7.1.1 and all stock 8.x.x versions, all of them working fine except the wifi.

No worries about the late reply, my Nexus is at LG service now, maybe they will repair it. But a solution for the wifi issue would be great, all my friends have a 5x (my recommendation), so there are some phones to repair. :D

Thanks for your great work!

bootloader not unlocked

Hi guys. For the first time in my entire life I decided to not put custom things on my phone so I thought it was going to have an healthy life. This lead to not unlock the bootloader on my Nexus 5X and know I'm crying cause it seems to be necessary in order to fix the BLOD. Anyone can help me to save my phone without the bootloader unlocked or there's a way to unlock it even if I didn't touched the OEM Unlock toggle?

Please, help me, thanks.
[Nexus 5X General] smuecke:
Hi.

I had the same problem, try to put the 5x in a cold and dry environment to cool it down. For me it worked fine, the phone started normal and I had about two minutes before it was back in the bootloop. Enough time to go to settings and do all the stuff to unlock the bootloader.
[Nexus 5X General] RegularSam:
It worked!

Thanks to your tip I were able to access to the OEM Unlock toggle. My phone is working now, I used the tool Unblod, just wifi is not working. Anyone has a solution? Thanks anyway for the great tool!

Also, I have audio problems, the speaker isn't working. I tried the audio on my headphones by pairing them with bluetooth and by this way audio works, donesn't work if try to connect by aux.
[Nexus 5X General] Cozmikk:
I went through the process and all seems to have worked well. Is this a one time fix or will I have to redo this process every time I reboot my phone?
[Nexus 5X General] monzer:
any rom and wifi work
[Nexus 5X General] Cozmikk:
Yes. Wifi doesn't work for me though. When I try to turn it on, it says it's still off. My MAC address says 02:00:00:00:00 and my ip says unavailable...
[Nexus 5X General] joenun:
i really can't remeber but i think i did it manually.

Great app though :good::good::good::good:

I tried your fix but I think it only works temporarily. The phone worked for a few hours and then started looping again.
[Nexus 5X General] Seliroth:
Hello Guys,

Last Saturday I got an issue with my Nexus 5x. I came back home connected to the WiFi and plugged it for charge. I answered to a few messages and left it. When I came back I noticed that it was off. I tried to turn it back on but nothing. Then I tried a soft reboot by holding down the power button. It switched back on, showed me the Google logo and switched off again. I tried the soft reboot again and obtained the same result. So I plugged it to my laptop. I opened the device manager and saw "QHSUSB_BULK". I put the phone in the freezer and when I took it out I was able to soft reboot again. And I noticed this time that after the first Google logo, the phone just goes black for a few seconds and comes back to the Google logo and after the second Google logo just goes off.

My first question is : Does it qualify as a BLOD?

If yes, I managed to get into fastboot by pressing power+ both volume buttons, but from fastboot the recovery and other options don't work. The phone just freezes when I select them.

My phone is running the January Android 8.1 update. So I tried the Unblod like I saw it at the beginning of this thread.

But I start the Unblod I always get an error saying it could not find "boot.img-cmdline".

Can you help me with this please?

Sending the phone back to LG is not possible from where I am. And I got to admit that I'm not really proficient in all these technical stuff, so maybe there's something I missed. I saw that the author said he was going to post a step by step guide and I have been looking for it but nothing.

Thank you

[Nexus 5X General] stratosk21:
If you've tried flashing stock firmware and it still does reboot after some time then yes it's a BLOD. Mine bootloops until it turns on then loops again later by itself. After flashing the fixed only it stabilized and became usable daily. I followed the instructions from another thread with the updated core fixes for Oreo 8.1.
[Nexus 5X General] Ahleksei:
Hi, my Nexus currently has 4CoresOreo.img (and TWRP), is that the kind of ROM you talk about in the first steps? And if so, should I instead go back to a stock ROM, would it be better? Thanks!

P.s. does using this fix mean that I'll be able to let the phone download the patches and android updates on its own?
[Nexus 5X General] theGeekyLad:
Hey monzer, it ain't a virus. It's a false positive. You can go ahead and download it.

Thanks!
[Nexus 5X General] theGeekyLad:
Hey Cozmikk, does it boot to bootloader when you hit the button combos? Also which kernel are you on?
[Nexus 5X General] theGeekyLad:
Hey Seliroth! Thanks for writing that out. There are many (self inclusive) that aren't proficient enough with tech but never mind, we all are here to help each other!

Also, answering your first question, the situation does qualify for the BLOD. That's exactly what you see on a N5X that's facing a BLOD. Furthermore, kindly let me know what more I could add to the manual guide in the OP to make it more informative!

It's weird that your phone freezes at the bootloader when you select the options - it normally shouldn't. Could be a motherboard failure if it really goes on that way. As far as the error is concerned on Unblod, did you load the right boot.img onto the program?

Univ exams are keeping me away from working more on the bugs, nevertheless I'll push myself but I'm here to help! Even if I'm a wee bit late in my replies, I definitely will. Kindly let me know, thanks!
[Nexus 5X General] theGeekyLad:
Hey Ahleksei, looks like you're already on a kernel patch (4CoresOreo.img) that solves the BLOD. You needn't really use Unblod if your phone's working fine with the 4CoresOreo.img. Unblod lets you patch your kernel to something like your 4CoresOreo.img yourself, for the latest system updates as and when they come out putting away the wait for the community to build one.

Also if you're really wanting to use Unblod then I'd recommend going back to a stock ROM which is foolproof. At the same time, other users do find it working fine on custom kernels / ROMs except for the WiFi that's yet to be fixed.

If you roll back to stock with Unblod, you'll still get the latest OTAs and security patches but the OTA's might brick your phone again as they come bundled with the latest boot.img from Google which empowers all 6 cores. The trouble is then to find the boot.img for that corresponding build which gets messy again. I'd not recommend OTA updates (even though you'll be prompted) but prefer flashing full factory images as and when they roll out 'cause you can then follow the guide as on the OP.

Thanks!
[Nexus 5X General] Ahleksei:
Oh wait, so with my 4CoresOreo I could let the phone install security patches and updates by itself, without doing anything? That would be awesome, because these days I've been blocking automatic system updates for fear of a new bootloop
[Nexus 5X General] theGeekyLad:
You absolutely did the right thing! You're on a 4-core boot image right now and if you'd let an OTA install (which comes with a bundled official 6-core boot image), you're phone would brick again. Don't let automatic updates on as they're certain to kill your device again.

Cheers Ahleksei!
[Nexus 5X General] Ahleksei:
Sorry, I'm back XD I'm not sure about what I need to do, having this kernel, about updates and security patches? (never used rooting/stuff like this before the bootloop)
[Nexus 5X General] zurik:
This tool turn off the 2 big cores on boot img file and then it flash on the device?
[Nexus 5X General] joenun:
after unblod you have to flash yourself
[Nexus 5X General] theGeekyLad:
Hey Ahleksei! Feel free to ask questions! Let me explain.

Stock kernel comes bundled with every OTA zip which is unmodified and hence runs on all 6 cores. Since our phones here are suffering from BLOD, we unfortunately can't run any 6-core variant and the catch here is that you can't prevent the unmodified 6-core kernel (in your OTA zip) from flashing. The OTA updates are handled internally by the Android system with little control left to us and thus the final point is simple, OTA updates are definitely going to bring back the BLOD. How'd you grab that latest update then?

Head over to the official Factory Images (https://developers.google.com/android/images) page to grab the latest firmware upgrade. The firmware flash process is mentioned in the same website. After this, your device still won't boot as even this factory image contains the unmodified, factory 6-core latest boot.img what I just spoke about, above. Now what you're gonna do is boot your phone into bootloader and leave it connected to the PC and follow steps under [Recommend] in the OP to get that kernel patched to 4-cores. Then leave it it to Unblod (follow the steps) to get the patched kernel and flash it I've over to the phone.

Hope that's informative! Thanks Ahleksei.
[Nexus 5X General] theGeekyLad:
Hey AFK269! That's precisely what it does - disabled the big cluster 2 cores.

Thanks!
[Nexus 5X General] Taldaerys:
Hey OP, i followed your tutorial but unfortunately it doesn't work for me. I took N4F26U, Apr 2017 as a factory image, but at the end of the day, my phone is still stuck in bootloop and i'm not sure why considering how it went well for others.

Your .exe was rather quick to execute (and it appeared that it was done given the final message) and after, the phone reboots instantly and keeps bootlooping

Can you help me out on this one? Do you think i need to disable the "secure boot" from bootloader? (not an expert so help is highly appreciated)

Thanks again
[Nexus 5X General] Dextor69:
i flashed many roms in my nexus 5x, now i dont remember which security patch in my device, can anyone tell me how to fresh start flashing?
[Nexus 5X General] benyben123:
Hi everyone.

Sorry for the newbie question, but does this work with STOCK 5x?

Mine bootlooped and I don't know what to do. Was running fully stock.

Thank you
[Nexus 5X General] theGeekyLad:
Hey Taldaerys! My apologies for the late reply. I'm assuming you loaded the right boot.img into Unload i.e. from your factory image zip as instructed in the OP.

Also, was your phone in bootloader / fastboot mode when you ran Unblod? If not, you'll find no effective changes. Needn't mess with the boot settings at all.

Do let me know, thanks!
[Nexus 5X General] theGeekyLad:
Hey Dextor69, get a fresh factory image from the Google Factory Images website and start with the guide in the OP under "recommended" section. You'll be then good to go.

Cheers and let me know! Thanks.
[Nexus 5X General] theGeekyLad:
Hey benyben123, it works best with stock on the 5X as the process is right from scratch with no ambiguities (easier) regarding the kernel in question.

I'm assuming you don't remember the build currently on your device. Consider downloading a fresh build from the Google Factory Images website and start with the guide in the OP under "recommend" section.

Let me know! Thanks.
[Nexus 5X General] Kun2210:
Guys, is it possible to use this tool to convert custom kernel's boot img? I was wondering if, e.g. it's possible to take most recent ElementalX kernel and somehow convert it to work on 4 cores and then flash through recovery.
[Nexus 5X General] theGeekyLad:
Hey KaoozAnders, could you send me the boot.img that threw this error? I'd like to test it in-house to check the behaviour.

Thanks!
[Nexus 5X General] theGeekyLad:
Hey Kun2210! I've seen people with successful boot using custom kernels such as the ABCrom kernel as on page 2 of this thread, by member enqless so I believe the logic works the same even for ElementalX though I haven't tried it manually.

I'd recommend you to try it out anyway and let us know! If the logic works, then it should boot imo.

Thanks!
[Nexus 5X General] KaoozAnders:
sure, I just took it from image-bullhead-opm3.171019.013.zip from the download (8.1.0 (OPM3.171019.013, Jan 2018)) from Google Factory Images (developers{dot}google{dot}com/android/images#bullhead). I have uploaded it to Dropbox just the boot.img if you prefer.

Mine has been sitting at least 20 minutes as well. It is on the repeating animating where I have 4 little animated colored circles and the middle two have the little yellow bar that connects them every once and a while... and that just repeats and repeats and repeats..

I flashed the Feb updates from google and then did the fastboot flash boot

boot-4core-bullhead-opm5.171019.015.img (followed by a fastboot reboot) to get to this point.

I'm not on Windows so I couldn't run the unblod.exe tool.

For me, the fix was a different version of the firmware. I think I ended up with the Jan version, but I might be mistaken (I tried several, and don't have the phone on me to check)

Was it the 2018 Jan version or the 2017 Nougat version?
[Nexus 5X General] tinonetic:
What difference is there between your method and the other ones?....

Hi,

I appreciate your time and effort for helping us all to get our 5X's up and running.

My experiences, as with that of many others, has left me with a sour taste in my mouth over Google's very poor support. It's over a year now, waiting for support. I bought mine from a Orange, South Africa (the mobile network operator). It then moved out of my country and left with false announcement that after-sales support would be provided by a third party. The third party declared it to be false....LG South Africa refused to support me and Google ignored me...

The rest, as you all experienced, is history....

My question is that I have come across so many solutions here, and I am not sure how different they are from each other, and which one I should take (I am a total newbie)?

[Nexus 5X General] AsItLies:
There are really only 2 things you can do (other than send it back to LG).

1) Use hot or cold to get the 'problem connections' working again. This is usually going to last for a very short period of time, say only minutest to hours. But it could be enough to recover data that isn't backed up (pictures and such), and also allow you to turn on OEM unlock and Debugging, if it isn't already on.

2) The other links, if you follow them, point back to this thread we're in now! So... this is it! If you are able (or already have) Unlock and Debugging on, then following the directions in the beginning of this thread will basically do this: You'll be able to boot the phone and load a version of Android (specific for the specific fix files) that will then be working on only ** part ** of the cpu cores. So, the phone won't run as fast or have the original full cpu capabilities, but it will ** work!! **

That's it. No mystery to it.
[Nexus 5X General] crocobarubehn:
I have to report a failure: followed instructions, still in BLOD, I would appreciate any help. Here is what I did:

1. Nexus 5X, in BLOD, stock, recent updates but was not sure which, locked bootloader

2. Cooled in freezer and was able to enable developer menu, OEM unlocking, USB debug.

3. Unlocked bootloader with fastboot

4. Downloaded 8.1.0 (OPM5.171019.015, Feb 2018) from factory images, got boot.img, tried Unblod tool - no help, still in BLOD only with the warning that bootloader is unlocked.

5. Flashed the whole 8.1.0 (OPM5.171019.015, Feb 2018) using flash-all.sh, then flashed the corresponding modified by Unblod boot-4-cores.img using fastboot flash boot boot-4-cores.img

6. fastboot reboot

7. Still in BLOD....

Any ideas?

Thanks!

Thanks for this tool!

My stock Nexus 5x started bootlooping yesterday. Reflashing stock (latest 8.1 and/or 8.0) did nothing.

After flashing either of them and then using your tool, the phone finally boots again!

However, it seems that wifi is not working (which has been mentioned in this thread) and more pressingly also sound. Neither speakers nor headset work, although bluetooth is fine.

Is anyone else experiencing this, or is it just my phone which is doomed?
