Nexus 5X bootloop of death fix (BLOD) | 7/30 Huge performance update!

[aljesco]

Okay finally I managed to heat my phone so it booted and I unlocked the bootloader!
After that I flashed it with Oreo OPR6.170623.013, Aug 2017 version with 4CoreOreo.img and finally it works!
Thank you very much!

I have a small question: is it a good idea to system update or should I turn it off at all and stick to the current OS version?

Thank you again!

Flashing From NRT??

What wouldbe the best way to flash from NRT and possibly flash something like Copperhead OS or Lineage? This is my second phone now but still want to try to save it if I can. Also It'snot boot looped yet it still runs fine.

Nexus 5X still bootlooping

Hi to all and a big thanks to @XCnathan32 for the great work! I managed to fix my sisters Nexus 5 X.
One week later to the first oreo update also my 5X started bootlooping. I firstly used another phone then last week i tried to flash the modified bootloop also on mine.

The light was blinking red, i heated up the motherboard and i was able to start the phone to unlock the bootloader. I installed the 48C nougat update and on top i flashed the bootloader. Now the phone boots, stays on for a few hous and then starts bootlooping agan. It freezes a few seconds after the 4 dots begin to spin.
If i wait for a few hours and i try to boot the phone it boots normally again for some hours.

Is my nexus 5X completely broken or has someone had the same issue like me?

thanks a lot!

Thanks so much to everyone who's worked on this and contributed feedback. You've literally saved a life (my phone's, but hey!). I'm currently sick and unable to work and can't really afford to pay my bills, let alone replace my Nexus since it bootlooped. You guys rock for doing this. I've not even seen a noticeable drop in performance.

Just a note on how I managed to unlock the bootloader: the freezing technique kind of worked temporarily, but the screen would be all frozen over and I didn't manage to get to settings. How it worked out was, I left it charging all day, and occasionally it would get past the bootloop and turn on for a while. I was clued into this because when that happened, my Amazon Echo would announce "Now connected to Nexus 5X [via bluetooth]". If you can't unlock the bootloader, maybe try plugging it in and leaving it on your desk and keep an eye out to see if it manages to boot sometimes.

Sorry I don't have any experience with that, just wanted to ask, have you maybe tried experimenting with some of the other kernels and boot images on the original post? Even if you have to use the slow version, it'd probably be better than nothing.

Hi, there! About flashing from NRT, yes, you can. Just take a look at NRT tutorial videos and you'll be fine to flash whatever rom you want with it. I did it like that, but I don't remember the option . You only have to select the flashing order. And about being safe, if your phone is not bootlooping, you can just turn off big cores (4 and 5) with root and apps such as Kernel Adiutor or Ex Kernel Manager (that's what I do). That way, you'll prevent phone from heating up! :good: Good luck! :fingers-crossed:

I chatted with LG and they said they will fix it for free as long as it is not damaged by water or mishandling, just have to pay shipping since it is out of warranty. If this is true and they actually fix it, I will be really impressed with their customer service. Still disappointed with the product quality control, but a free fix offer is about as good as you can ask for given the situation.

I was lucky that LG accepted my case and I got a new motherboard (which LG claims will not boot loop!!!) free of cost at their service center here in Delhi, India. It is working fine on Oreo even after two patches.

Thank you again!

if you do a system update you will go back to the BLOD. so, turn off system update and stick with what you have...

So assuming I read this right I can just add the 4 core zip file into the list of what Im flashing and it should just work and turn off the cores that cause it to heat up? if that is the case I can definitely try this tonight! Does it need to have a custom recovery as well?

Yes! AFAIK, you can add any zip and flash. And it would be the best to add the 4-core TWRP, so that you can boot to recovery withohut going to bootloop. Let us know the final results and good luck! :fingers-crossed:

I've received a new motherboard on January with the same claim, now it's October and my phone i'ts on their hand again...

This time it got frozen on the screen with the warning "this phone has been locked for more than 6 hours, you need to use unlock code".

On Topic.
Thanks for the new solution guys, when my phone dies again I will try it

Does this core4Oreo affect my phone's warranty?

Before sending it to LG...have you tried the solution mentioned in this thread?

Actually my phone got this issue before a month and thanks to this thread for making it alive again. But today my 5x frozen again and this time it is not getting start. Nothing worked for me so I went to LG service center and told them after bootloop today my phone not even getting screen on. So they told me to bring it on Monday, we know about bootloop. My 5x is 13 months old.

If you flashed the October factory image, you need the October 4 core image. Try this. (For some people it wasn't working too) anyway give it a shot.

hmmm....OK. I'll try this too.
But the problem I am facing is *continuous bootloop* irrespective of booting the phone or even in Recovery,, the recovery just doesn't stay more than 30sec, leave aside going past the Google Logo.

Hi all, needing some help here. I successfully flashed 4coreoreo, but when I issued the fastboot reboot command, the phone just turned off. I waited for about two hours thinking that it was just taking its time, but it never recovered. Now I can't even get into the bootloader, so I can't try doing it again, or flashing a factory image first, etc. I know that its not completely bricked because I briefly got the Google logo to come up, but nothing since then. Anyone have an idea of how to get the bootloader up again?

If you want to go into the recovery, you need the 4-core recovery to be installed. You'd be able to go to the bootloader, right?
