Not Booting - Nexus 5X Q&A, Help & Troubleshooting

Hi, I was using DU, I opened an app, the device stuck I hard rebooted & it got stuck on boot animation (boot animation stopped and stuck) I flashed full stock ROM & it's on Google logo please help, wiped everything, recovery not booting either..

It seems that your 5x is mostly dead due the HW bootloop problem. The problem is in the solder connection between the cpu and the emmc memory. If your phone is still in the warranty period, ask for a refund. If not, you can try to open the phone up and reheat the emmc and cpu manually ( with a hairdryer for instance) to restore the solder connection. It can work, but it isn't a pernament fix. Some people said, that after this "fix" it worked for a while, but the problem came back after months or even weeks

Thanks for reply, I figured it's a hard brick as it booted once somehow (charged before a lil maybe it triggered the solder to "fix" temporarily) it went down again within an hour I gave it for service, under warranty, the service center said they'll fix it (motherboard replacement) have warranty only for 3 more months now.. Wish the replacement motherboard doesn't have the problem..

[Q] HTC Desire - another one randomly rebooting

Hello, erm there is a lot of threads about this but I find most of them with lack of information.
My device is:
HTC Desire
HBOOT 0.93.0001
ROM Amethyst RC7
RADIO where to see that
RECOVERY RA-desire-v2.0.0
The phone shutdowns after like 10min of being idle. Then usually its unable to turn on. If it is connected to a power source then nothing happends.
I have tried to RUU, Factory Reset, Other roms, No apps, 3 batteries and such. It started some days ago
I attached logcat too, any ideas?
EDIT: It also randomly thinks that the jack stick is plugged in
Send your device to a repair centre.
Damaged in any way? Dropped? Moist damage?
I have my desire since 2 weeks, with the latest update and unrooted, original f/w.
It has rebooted twice already while in call, what's funny is that it happened exactly at the same place (in the same subway station but different days), so I'm wondering if it could be network related or when it's switching from 3g to gprs...
After the reboot I can call normally from the same location.

Damaged by water, but it first started some days after, and I splitted my phone and dryed all parts
Then send back to repair... Water could've damage anything, which makes it working like that (probably faulty motherboard).
I cant send it to repair since I've opened it and replaced some parts
Then replace what you can, because it does not look like a software problem, more like damaged hardware.

Potential bootloop (?)

So I know the bootloop issue is a well known issue. And it looks like today it was my phone's turn.
I was browsing chrome when, all of a sudden, it freezes on me and turns of itself. Since it wouldn't turn back on, I tried swapping batteries (I have a spare one from the extra battery kit), and once turned on, it was bootlooping.
Desperate alredy, I get on my notebook to see if there's anything at all that I can do. After I while (don't know exactly how much), I turn back to my phone, and see it's on the lock screen.
For the moment it's working fine, I even turned it off and on, and restarted it.
What do you think about it?
Backup your stuff off the phone? Once a week.

You can try the blown drier trick, remove the battery and using the hot air at around 10 cm of your phone move back and forth for 5 minutes, then put the battery back and see if you can backup the data. Afterwards you can play with it. Normally this is not helping for more than a couple of hours.

try freezer method to recover data, if important then send it to LG for repair if under warranty.
For anybody that even care remotely, I didn't attempt any recovery method, and sent it to LG for a (hopefully permanent) repair.
Btw, is there a way to know if they replaced the motherboard, or the fixed the actual one?

It will come with new IMEI number and new serial number (e.g. 607 like mine) if the motherboard gets replaced. Also they will state in the report that they will send back with the device on what has been done to the device.

Nexus 5x shut off and won't turn on

If I posted this in the incorrect place or there is something related to my issue, I apologize in advance.
I've been searching here and all over the internet and no progress yet so I decided to make a new account here just to see if anyone can help me because I'm out of ideas right now.
This morning my Nexus 5x (Non-rooted Nougat) woke me up like every morning, after dismissing the alarm I left it on my bed and when I came back to grab it later I noticed it shut off.
Here are the facts and what I have tried so far:
- Battery level was almost full
- I tried to turn it on but nothing happened, not even the Google logo
- Connected it to power and no icons or any response at all
- Left it connected for like an hour and tried to get it into recovery mode
- I was able to get into fastboot mode a few times but after electing "start" or "recovery mode" the Google logo comes up and then shuts off again right after.
- Tried getting into recovery mode after leaving it charging for a while again but I couldn't even get into fastboot this time, no signs of life at all.
- Disconnected the battery for a few minutes and tried to get into fastboot mode again, this time it worked but same thing happened. (Google logo then shuts off)
- Tried connecting it to my PC but doesn't show up on Linux nor Windows, on Windows it makes the sound like I connected a peripheral but that's pretty much it.
- I have USB debugging enable but never accessed my stuff through usb connection because I have had this issue before where it is connected but it won't show up or it shows up but won't let me access the files even though the phone is unlocked.
At this point it just won't do anything and I ran out of ideas. I just want to at least recover some pictures and information I have in it that isn't backed up, if anyone can help me I would greatly appreciate it.
Thanks in advance
It sounds like you might have encountered the hardware bootloop issue. This is theorized to be caused by bad solder for the eMMC chip or bad eMMC chip. This was an acknowledge problem on a related model LG phone, but hasn't been acknowledged for N5x.
If you are under warranty, you should start the replacement process before it runs out.
If you want to try something that sounds crazy but has worked for some people, put the phone in the freezer for 15 minutes then see if it boots. If it does, quickly back up as much data as you can, then wipe the phone in preparation to RMA exchange.
Just boot to bootloader (fastboot) then unlock it and flash a factory image... u can find many guides to this operation on the XDA

Same here... cannot enter recovery mode, so flashed new rom stock rom.
The flashing was fine but it didn't help.
guys if u can get to the bootloader, sure it can be fixed.. everything is possible with the fastboot, u can fix any issue. if it's a hardware issue the bootloader wouldn't work as well.

I've had the same problem with my 5X, except my alarm didn't even go off! I woke up 15 minutes late to see the boot screen "enter your pattern to start Android". I entered my pattern and it looked like it was going to boot up but when I went back to it it was blank. Tried again, got to the Google loading dots and it switched off again and I haven't been able to power it up since. No bootloader, nothing. Tried all the troubleshooting steps on the Nexus Google Support pages (I did post a link but because I'm new it won't show, so just Google "Nexus Support") and nothing worked. I also knew the battery was fully charged because it had been on charge overnight and when I did get to the 'enter your pattern' screen, the battery icon in the notification bar was full.
I requested a call back from Google and nothing happened so I tried the chat and they said it sounded like a hardware issue and are sending me a replacement device within the next 3-5 working days. Good that they're replacing it. Bad that it happened on a device less than a year old and they only offered £10 Play Store credit by way of compensation, when I've had to spend £15+ on a PAYG sim card to use in my old phone in the meantime because the nano sim in my 5X was too small and I've spent over an hour and half this afternoon wasting my time with troubleshooting and waiting for a call back... Not really the customer service I expected from Google for what appears to be a hardware issue. If you bought the phone from Google, my advice would be to get in touch with Google Support and they should replace it under warranty.

I contacted Google and they didn't help me at all because my warranty expired last month, they literally just told me to put in a repair request at the LG repair webpage....this sucks
My experience exactly...
My wife's Nexus 5 exhibited the exact same symptoms this morning. It's been running perfectly for 20 months and today it died, and we're unable to even get into the bootloader screen or power on the phone.
Taking your advice, we put it in the freezer for 15 minutes and were able to perform a factory reset wiping all data from the phone. We are going to take advantage of Google's Christmas 2017 promotion and return the Nexus 5X and buy a Moto 4X. They require you perform a factory reset before returning the phone in order to receive a credit for the returned Nexus 5. Thank you so much for the help!

I've just posted this thread overlooking yours. I think this is becoming another common issue. Has the freezer trick worked with anybody else?
I am having the same issue described here. My Nexus 5x went into a Bootloop about one month ago, but I was able to get it working again by going into Recovery Mode. About 4 days ago it went into a constant Bootloop, just showing the Google screen, and I couldnt get back in to recovery mode. I ordered a new phone on Tuesday (Pixel 2) and as long as I am able to do a factory reset I should get a $150 credit when I send this phone back. So, in desperation, I took a chance on the 15 minute freezer trick, and it worked! I was able to get into recovery mode (power + volume down, select Recovery Mode, little dude on his back came up, pushed power + volume up once) and cleared the cache and applied the factory reset. Ridiculous that this phone only lasted 18 months, but if I get the $150 credit I will be happy.
Same problem here -- just froze for a few seconds, powered off, and won't turn back on. Not a boot loop issue as there is no response at all from any buttons. Swapping the mainboard from a working phone powered up without a problem, but obviously that's the other phone's emmc.
I tried the freezer thing and it sort of worked- LCD powered on for a couple seconds, but then shut back off again and even that only happened once. That's progress over the usual absolutely no response though... Anyone have insight into why the temperature would matter? something is overheating that this gives a bit of wiggle room since it starts much colder than usual? maybe a more complex analog electronic situation?
I would happily pull the flash chip off and put it in a emmc reader, but I think I'm out of luck because from what I've read the dm-crypt key is generated from some data stored in in the processor's trust zone thing. I know the "password" but if that's only part of what makes the key and the rest isn't on the flash chip I suppose there's no point in going that route.
I don't care about the hardware surviving; mostly just looking to recover my data. Anyone have suggestions? Hardware debugging direction? I'm willing to buy some electronics test equipment (within reason of course; not picking up a 10000USD rework station for some old photos and contact list...)

The only way to connect that buddy to PC is to get SoC (CPU) working, so theoretically you can go towards reballing the chip. But I guess it's not an easy thing for such a little chip. Also u will need kinda plate for balls, i think there are no common ones, so u can make it yourself if have a technical education.
Another way is to connect memory right to PC without a phone but with some connector. IDK if there are any available, but this looks much more simple. I actually got the same happened, and tried to heat the plate, but with particular success.
IMHO

Here's the reader
https://www.amazon.com/ALLSOCKET-eMMC169-Programmer-Kingston-Interface/dp/B06Y55DKND/
But I assume the problem is I will not be able to generate the encryption key because part of it is in the processor.
If someone has tried this and it definitely works, I'll give it a go. Just don't want to buy the emmc reader and heat gun this chip off if it's certainly a waste of time.

Nexus 5X hard bricked. Is there definitely no way to fix it?

I have a Nexus 5X (running Oreo 8.0 rooted) which was working fine until yesterday. The phone was responding very slowly so I decided to power it off. After that the phone will not power on at all. When I connect it to PC via USB, it shows up as "QHSUSB_BULK" in device manager. I have read online that this means the phone is hard bricked. I bought the phone in June 2016 and the warranty only lasts a year so I can't RMA it. What should I do? I really liked the 5X and nothing out there really compares to it.
@gwynlordofcinder: sad for you. But why you ask the same question as 20 others before? Try freezer and/or oven to get back the mainboard-connections. If successfull, you can save your data or go on with a kernel-profile which makes the big core sleep. Use search for details.

They have extended the warranty to 18 months, or someone said 24 months, since there is a hardware issue with the 5X.
Most likely fixable, but with the need of special files.
Search up on QD Loader 9008 on this subforum and read through it.
i'm on the hunt to find a fix for it, hopefully i'll make it. gonna share my findings asap!

Since this happened from normal usage and not from you installing a custom ROM or updating the bootloader, or something like that, I think you have the bootloop problem. I normally think of a hard brick being the result of flashing say the incorrect bootloader, or a corrupt file, etc. which can then hopefully be undone by software means to get the right software back on there.
If you have the bootloop, it is a hardware problem. The fact that the phone doesn't bootloop does not mean you don't have the hardware problem. Boot looping was just the most common way to identify it, but many, like mine would just either never even start booting, or would start, then go black.
If you don't figure out any software way to do anything, then try to look for bootloop fixes. Searching for that might get you further. But with a hardware problem, everything except the fix for disabling the big cores (in XDA threads), is temporary unless you are lucky.
Assuming you have a hardware issue, here's some steps to maybe try. I was able to get the rescue fix installed on my phone after using a hair dryer on the motherboard. But that didn't fix anything since my problem was hardware. But if your OTA update was maybe slightly corrupted, maybe it'll help.
https://productforums.google.com/forum/#!topic/nexus/G_0s70PzK_s
To jump right to trying a rescue OTA, go here:
https://productforums.google.com/forum/?utm_medium=email&utm_source=footer#!topic/nexus/hdrNONCCoNE
If it doesn't react enough to do anything from a computer, you may have to resort to putting it in the freezer for a while first. Which may give a short period where it'll boot and you can maybe adjust the settings so you can try one of the XDA fixes that disable the big cores.
One fix that disables the big cores:
https://forum.xda-developers.com/nexus-5x/general/untested-nexus-5x-bootloop-death-fix-t3641199
Example video of heat gunning the motherboard. He did hair dryer, but then did it again with a heat gun. That's in a separate video of his. By using a heat gun, I was able to get it to where I could pull my data off and it even acted normal for 9 hours. Then rebooted and then eventually ended up bootlooping. The fix to disable the big cores was not around back then, so I never have tried it, and ended up getting the 5X replaced by Google.

except that the files needed for unbricking corrupt bootloaders/eMMCs' are so hard to find it's incredible.
bought a used 5X that "suddenly died in a pocket", now that you mention all of this, i might try doing the hardware fixes and then apply the big core disabling and hopefully get my phone to work.
the phone did get serviced though, so they might've installed bad firmware since the phone is in QDLoader & in EDL mode (PC recognizes the phone, while fastboot/adb/LGUP doesn't)

Questions about bootloop, warranty & repairs and heatsink mods

Hello!
Unfortunately, just some days ago my 5X died. Was on the table, it rebooted itself and then it was stuck in a bootloop. I wasn't even able to use the recovery, and none of the 4-cores mod worked to help me get some of my files. I even opened it, disconnected the battery and reconnected it, but nothing.
So, I send it oot for repairments; luckily I still have 3 months of warranty (I live in Italy). However, I have some questions that maybe you can help me clear out:
Will LG be able to see that I opened the back cover of the phone and also that I modified its software?
Before sending it, since at least fastboot was working without issue, I flashed a stock factory image of Oreo and re-locked the bootloader (also like this, it wasn't booting however), so it was totally stock, but they can see that the bootloader has been unlocked and relocked?
I'm a little worried about LG discovering these things and make me pay for the repairments...
Hoping to getting it back repaired for free, will it be safe from the bootloop issue or it can happen again? Since it's a known problem, does LG started repairing with motherboards with better solderings, or I will find myself in the same situation as now?
If answers to question 2 is "no, they will put inside it the same faulty motherboards", there's anything I can do to prevent this issue? I saw someone using copper plate heatsinks to contrast heat, what do you think about that?
Thank you!

Hi, I'm Italian too and I had your same problem.
1) My phone died and 20 days before the end of the warranty and I sent it to the repair center.
As you, I opened the device and also I wasn't stock, so I reflashed google stock image and I re-locked the bootloader. The repair center has fixed my device changing the mobo and they didn't charged me for anything.
2) I don't know if they have a new rev. of the mobo that fixes the bootloop problem, but I'm going to apply the copperhead heatsink mod and maybe I will underclock the cpu with EX kernel.
3) I hope that the copperhead mod works, I saw some benchmarks and it seems that this heatsink will lower the temperature by 5/7 degrees.
I'm sorry for my English

We have exactly the same situation, I just ordered the copper plates, let's see if it will work! As of now, even if I got my 5X back from warranty, I'm still using my galaxy nexus because I don't want the 5X to overheat, I will start using it again after the heatsink mod
