5x hardware bootloop cause / fix ?

[ACHILLES R32]

You need to charge it for sometime. The battery is totally depleted.

Thanks for the reply , left the phone plugged in the charger for a bit. Then put the phone in the freezer for 15min .. Got it to boot into bootloader but computer can't recognize it ( wanted to lock bootloader and un root) but it froze and I have not tried since.

1) Open device manager and check if you can find your device anywhere in unknown devices or android devices
2) If you can find it anywhere, select Properties > update driver > select android devices > done
3) If not, uninstall all android based drivers > reboot > reinstall only minimal fastboot drivers and then check if it gets detected.
4) If no, check if LG tool detects it.
5) Spoiled USB port or cable
6) Device effed
Uninstalling and reinstalling drivers worked for me.
Try it.

Thanks, Was able to turn the phone and access the bootloader. Flashef stock, went to relock bootloader phone froze and have not been able to turn it on since. Seems to turn on once a today or so. Will try in the morning lol. Friday its going to LG wether I lock the bootloader or not. Not sure what I will do at this point , almost got a pixel but then started reading about speaker issues. And decided not to deal with more problems ?

LG didn't change the hardware earlier this year'? As I was reading that most people that is suffering this issue are people who bought the phone at launch (oct 2015 if I recall).

I bought this phone a week a go. As far the phone hasn't doing anything strange. The production Date of my N5X says 9/2016 so I should be safe for a while right?

Hey guys
So this hardware issue can be fixed using unbrick method ? I saw some thead regarding that in QnA section only

Thanks

Wow, 9/2016 is the latest I've seen for production date. I don't know if you'll be safe because LG hasn't released any details about when they realized the problem.

The reason you see so many postings with the 9/2015 or 10/2015 units is that was the largest production run and the ones where people are on the edge of running out of warranty. Before that, people just return under warranty and aren't in panic state. Also it seems to be taking aroun 10-13mo of heat/cools cycles before the solder joints develop microfracture and there was some publicity recently drawing attention to the issue.

My personal WAG guess is this is affecting maybe 1-2% of units, but when this type of problem should be affecting .01%, that is 100x more cases than normal and gives the impression of widespread failure due to the people posting.

If you have the hardware bootloop, it cannot be fixed using unbrick method.

If you have software bootloop it can.

Symptom of hardware bootloop is usually you are in the middle of doing some basic operation, the phone freezes, then starts bootlooping forever, especially if on a stock unmodifed phone.

Yes that's why ask if LG acknowledge the issue at that time.

By the way I know that my unit was produced 9/2016 by the first 3 digits of my S/N (609) so the first number is the year and 2nd a 3rd are the month. I am right?

I don't know if I should keep this device really as in my country all the phones are super expensive ( I bought this one because I'm in a trip and my Nexus 5 is almost dead) and we don't have LG customer service nor Google

Packed up my phone and sent to LG hope they repair it. Returned to stock but could not lock the bootloader. Phone froze after it was returned to stock. Have not been able to turn it on for 3 days. Will post updated once I hear back from LG

I could have probably locked my bootloader but forgot before sending it to LG.
I was able to get in to fastboot mode and flash the stock Nexus images after it locked up and rebooted but get stuck on the Google boot image.
I hope LG doesn't be little *****es and deny my claim based on the unlocked bootloader. I only unlocked it after having reboot issues previously and wanted to flash a clean image. It didn't help. Few days later it bricked.

Oh no ... I'll better exchange my Nexus 5x for a new device
Can you tell me which one should I consider ?
Thanks
I have low budget now and hence I would like to buy a phone within 15k INR (~230 USD)

So you was able to flash a stock system when you had a hw bootloop?
It's a good news, because we don't need to be worry about warranty if we got that problem

 

[Psychofrantics]

OK guys. here is my rant.
I owned 16 gb nexus 5x h791. I bought it without warranty. Was using stock rom with elementalx nexus kernel (Hey, it is awesome. You must try it). Felt adventurous. Overclocked the cpu and change minimum gpu speed to 300 MHz. Bought my first app (nova launcher premium) from play store. Installed another app and bam.. N5X froze. Used volume up and power to restart it. To my dismay, I was stuck on google logo. F*** You LG.
Flashed factory images with no luck. Phone will not go past google logo. Flashed7.1.1 and 6.0.0. factory images. TWRP will not stick too. Tried two days with no luck. Screw you LG.
Went to market. Shopkeepers didnt have any idea. One said that I will reflow solder it. Agreed for 10 $. He reflowed but software was also corrupt. Didnt get past google. Thought I wasted my money. Went home despaired.
When I reached home, i saw that a blank screen is on. Some times recovery screen flicks. Fashed latest factory images and it booted. No I am scared to even restart it. Dont know how much time it will work. But one thing is sure. LG messed the solders. So anyone who is out of warranty should try it. It may work

Yep, but I didn't even try to lock the bootloader. Some are reporting they cant

Hm, maybe it's better to flash the stock rom, and disabling the 2 bigger core with this:
http://xdaforums.com/nexus-5x/help/bootloped-hw-please-try-t3505392
Then lock the bootloader (hope we can at this way and yes now we getting hardware and software bootloop mix )
and send back to LG.

I think they find out earlier the unlocked bootloader than the costum kernel.
But if the news are true, LG doesn't fix 5x anymore, they will refund you. So maybe they just try to turn on (yes now they see the UB, but can't see costum kernel) or enter stock recovery and if it's not succesfull, they refund you.

 

[shonak24]

Is there a way to prevent those hardware issues? Maybe use custom kernel UC or something like that... I'm using nexus 5x and my warranty is about to run out

For hardware bootloop, I would say this behavior is highly YMMV.

 

[sfhub]

Flashed factory images with no luck. Phone will not go past google logo. Flashed7.1.1 and 6.0.0. factory images. TWRP will not stick too.

If you could even flash the factory images, then it is likely you didn't have hardware bootloop in the first place.

If you want TWRP to stick, you need to install root (which modifiies the boot image) or modified boot image.

People are reporting they can't get refunds anymore.

Their options are to wait weeks for parts, get a G4 in exchange, or if you complain enough, sometimes they offer G5 in exchange.
