Phone suddenly hard-bricked. No recent flashing. - Nexus 6P Q&A, Help & Troubleshooting

Hi everybody,
What Happened:
My phone has suddenly become totally unresponsive. I have been using it most of the day, it was sitting at around 70% the time that it happened, but it is now a totally black screen. I had just taken it out of my pocket and it was suddenly like this.
The only idea I could come up with as to why this happened is that I charged it off of a JBL Charge 2 last night. I'm not sure if that may have messed with the battery, but I do find it odd that it's totally unresponsive while plugged in.
I was running android 7.1.1 DP2, with the ElementalX kernel 4.0 I believe. I was also rooted with SuperSU. What's really odd is that I hadn't done anything new recently besides install uTorrent and VLC media player. Otherwise, my routine has not changed one bit. Up to when the phone actually died, I hadn't even used either of these new apps the entire day.
What I've Tried:
I have tried plugging it in via AC, via USB, I've tried booting into recovery or fastboot, but there is zero response from the phone. No indicators on the screen, no LED blinks, no vibrations, nothing.
What I'll Try:
If anyone has any experience with this happening, I could use some advice. Otherwise I'm just going to wait it out, consider an RMA I guess. However, my device did have the bootloader unlocked and was rooted, so.... I hope it comes back by itself.

My advice is to keep it plugged in, or see if there is a response on the computer perhaps on fastboot, upon using the bootloader keys. I haven't had this, just a few suggestions. Good luck!
PS: A RMA will probably be needed, there are much more experienced people around here. Sure you may get replies later.

Good luck?problem all nexus 6p!!! Lg responds repay helps, hawuei what to do? problem arises with nogaut not be our fault, how to fix this? My phone now in service but to be fair this? warranty and having to wait ..

[Q] Continuum, what have I done?

Hi everyone, I'm new to this forum (first post), I've owned my Continuum for a few months now happily with no problems. I actually love the phone! But recently I ran into a pretty big problem...
Let me give you a little background on my phone first, I have used SuperOneClick on it, to grant super user permissions, I've used the program to grant me access to the phone tethering apps that are out (currently using Open Garden), and the AdFree app in the market. I havn't used anything else in regards to 'hacking' my phone so I'm a bit confused as to why I'm getting trouble.
Anyways here's my problem, lol! Well the other day I turned off my phone and tried turning it back on and I would get a grey battery with the spinning disk, and it wouldn't turn on :\! I tried holding all the buttons, for over 10 seconds, no avail. It still turned on to the battery and nothing. I tried taking the battery out for a whiiiile and nothing. Eventually I plugged in my phone to the wall and it magically worked. Actually that's the only way I've been able to get my phone to turn on lately. It works fine once it's on but every time I turn it off the same thing happens .
So that's truly why I'm here... Is my phone 'bricked', or are these some symptoms of being 'bricked'? Are there any fixxes I can go about taking to you know...fix the problem ?
Any help would be Greatly appreciated,
Thanks everyone,
-Matt
Oops, I forgot to mention that my phone has been acting strange sometimes in the sense that I plug it into the wall and the 'Mass Storage/ Media player' option comes up, even though it's not plugged into the computer, just into the wall.
Pretty strange huh?
Anyways thanks again everyone who helps!!!
Can you try taking out the battery, then putting it back in...
Then hold down the volume down key as you power it back on?
I would try un-rooting and doing a factory reset... that should eliminate software issues... If you're still having issues then take it to VZW and let them give you a new one.
This is not "bricking"... If a phone is "bricked", it does nothing, absolutely nothing, and the only way to make it useful is to use it to build something.
Sure, right now it says "Downloading... Do not turn off Target!!!".
Thanks for letting me know it's not bricked, that's a little reassuring .
After a while I just took out the battery and stuck it back in and attempted to turn on the phone the usual way, and it turned on just fine. I'm guessing it's fixed and hopefully it won't do that again.

kindle fire refuses to boot.

I installed cyanogen and TWRP on my fire a couple days ago. It was working fine but today i was playing a game boy emulator and it shut off on me. the battery was completely dead at the time (i was playing plugged into a wall, and it had been totally dead for about half an hour) so i figured i just bumped the cable or something, the problem is it won't charge. when i plug it in to a wall, PC, what have you. it boots to the fire logo and asks me to press power to enter recovery (as it should) but then it just turns off and shows the same screen. i left it alone for an hour and it was still doing this. when i try to power on without being plugged in absolutely nothing happens. I've tried my usb cord and two different chargers, all of which work with my phone perfectly.
i think this is a hardware issue(please tell me otherwise) which would suck because I'm pretty sure everything i did voided my warranty. any suggestions or am i just boned?
well i contacted customer support and they didn't seem to care at all about the root, they told me it was a battery issue and are sending me a new one. good news for anyone wondering if rooting voided warranties, it doesn't.
That's great to hear that Amazon isn't going to be a **** about it. It is one thing if someone screws it up because they rooted but a hardware issue is a hardware issue and it is a good sign that they are not looking to screw you merely because you happened to have rooted coincidentally to having gotten a dud unit.
this same thing happened to me it seems. I was playing a game and my KF died. so I charged it for awhile but now its in the same type of weird loop, just like yours. Even after successfully issuing commands to change the bootmode etc, which I can only do like 1% of the time since it keeps rebooting. Hope its not a hardware issue though
it is a hardware issue, at least thats what amazon said. i fixed mine yesterday though, plug it in wait for the loop BS to start and hold the power button until it stops completely, then wait about 20 seconds release and press the power button again. I've had to do this twice today too, so definitely get a new one sent out, but it works for now.
I wonder how friendly Amazon will be after replacing a few thousand of these because people are screwing them up???
Seriously haven't seen this many "help I bricked my device" threads ever in a forum.

There are a lot of "I bricked my device" threads but the vast majority are having driver issues or stuck in the wrong boot mode. Almost everyone I have seen posting with a problem gets it sorted out and has their Kindle Fire working again.
The OP here appears to have a genuine hardware problem, according to Amazon, and didn't "screw anything up".

Stuck in APX mode won't boot or turn on / charge - any fix yet?

TL;DR: Any way to fix/flash a Nexus 7 that reports it's in APX mode to Windows yet, that won't do anything else?
Backstory: I've had a 2012 Nexus 7 32gb since the day it came out (Oct 2012 or so?). Worked great for a year, loved it! Had AOKP on it, unlocked/rooted, used tons of apps, never a single problem. And then one day while I was using it to play music while charging it, out of the blue, it hard shut off while it was running, rebooted and shut off during boot and... never turned on again. Wouldn't indicate a charge, wouldn't turn on, couldn't get it to respond to any power or volume key presses, nothing.
I called Asus, and they agreed it needed to be repaired. I sent it to them, they sent me back the same unit, repaired, and said they swapped the mainboard out in the repair notes. Worked great, except the device was completely wiped, relocked, unrooted, and they removed my nice Stenheil screen protector.
I was without it long enough that I got used to not having it. Since it was completly back to stock, I decided instead that I would sell it when I found a good buyer (friend, etc), and buy the new 2013 Nexus 7 instead. I found a friend who wanted it a few days ago.
Today's Issue: I charged it over night last night so it was on a full charge this AM. I saw that I was still running 4.3 on it (hadn't really used it since I got it back in November), so I did the factory/official "OTA" update to 4.4.2 this AM. Went flawless, no issues, booted up fine. I updated all the apps on it, also worked fine.
I then decided to do a Factory Reset on it, (Thru Backup/Reset IN android, NOT Recovery). I went thru the confirmations/warnings, and then it said "Shutting Down..." and, it shut down. I let it sit for a few minutes, expecting it to boot back up (it never did). I tried to turn it on, nothing. I tried ALL combinations of power + volume, + charging cable in/out, etc. Everything possible, trust me, I scoured the web for new combinations and timing ,etc. No matter what, I never got ANYTHING on the display, no charging indicator, no recovery or bootloader, nothing. It's like the display is dead. The battery was fully charged this AM after being charged overnight so I know the battery wasn't even close to low. It's like it's completely dead no matter what I do.
I then tried to hook it up to my PC, which is setup for ADB etc, couldn't see it in ADB. In Device Manager though, it's showing as being in APX mode? So I tried holding power down for 10 seconds with it connected, and it DOES disconnect from windows, and a few seconds later, it shows up again, again in APX mode. Nothing ever appears on the display. Holding VOL down or all three buttons while plugging into PC never changes anything, no matter what, it ALWAYS shows in APX mode.
From what I'm reading online, this is a sign that the bootloader is missing or corrupt, and, that there isn't a fix for that unless you first backed up your crypto "blob" using Flatline (which I didn't even know about till today). I'm hoping that maybe what I've read is out of date? Is there perhaps a way to fix or flash this yet?
The whole thing makes little sense. All I did is update it, then reset it, all officially supported/normal things, on a bone stock tablet. It seems more like they didn't ACTUALLY fix it the first time it went back to them....
Help? AFAIK the tablet is now out of warranty. I just want to sell it and get the 2013 model! The tablet is in perfect shape, it's been used with a screen protector and case since day 1 - not a single scratch on the screen or case. :crying:
i'll take the silence to mean I'm screwed, right? :crying:
I don't know how, but it seems your bootloader is gone. (corrupted sector on the nand,maybe)
You can't do much without the proper blobs.
If I were you, would try to send it back to Asus. They are the only ones who can repair it.
Wow I can't believe it's been two months, but, I still have this tablet, still not working, Asus won't fix it for a reasonable price... anything changed on this in the last two months?
It seems like it should be possible to do something... maybe I'm just optimistic.
I want a 2013 Nexus 7 but it's hard to pull the trigger knowing my very lightly used gen1 model failed twice now.
There is no way to produce an universal blob and device specific blob creation is working so there is little to no reasons for further development.
You could fit a new motherboard 32gb ones are expensive but the 16gb are a lot cheaper
Programming is a race between engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.
They're readily available on eBay - $35 for a used 16GB motherboard, and $50 for a 32GB board. That's how I fixed my APX bricked N7...
Whoever stumbles across my late entry, if the N7 won't boot after empty battery, no button combinations work and PC shows only APX mode - take off the back housing (it's pretty easy to do) and disconnect and reconnect the battery cable, this let me boot it up immediately...
(my N7 however was plugged over night to charge before I attempted this unplug but actually didn't show up the charging indicator and wasn't bootable, surprisingly it was charged already half when I finally could boot it up)

Apparently it is possible without having done the backup first, at least for some people.

Phone finally booted after 3 day boot loop..

I decided to start a thread because I noticed there were multiples about this issue. So 3 days ago I was on Facebook when my phone randomly froze. I pushed the power button, and that's when it began bootlooping. I instantly tried booting into recovery with no success. I was hopeful, however, because I could still access the bootloader. I got on my computer and began researching the issue and steps I could take to fix it. I tried every method out there and was unsuccessful. I ended up buying a Pixel today off Craigslist and am loving it so far. So anyway since my Pixel came with the OEM charger, and I had been using a non-oem ever since I had my 6P, I decided to plug in the OEM and see what happens. Within the first hour my 6P began to get very hot, almost to the point where I couldn't even hold it in my hand. Keep in mind the phone was still consistently boot looping the whole time. So I decided to unplug it. Well I left it sitting and went about my business and when I came back to my bed I noticed it was doing the Google boot animation!!!! I started freaking out! After it booted up I finished the tutorial stuff and just let it sit on the home screen for a second. I noticed the battery was low so I figured I would plug the charger back up and let it charge. Well in the time it has taken me to write this post, it just started boot looping again... Lol. So I just unplugged the charger AGAIN, to see if it will boot up again. To me, it seems like there might be a hardware issue with my battery. Anyway, my 6P was rooted and running nitrogen OS (wasn't running the latest build but was 7.1.)
what are the exact symptoms? and does it boot into bootloader and recovery if not what is it physically doing?

As of now it is still boot looping and no it doesn't boot into recovery. Only symptoms I've noticed is the phone starts to get extremely hot when I plug in the OEM charger that came with my Pixel. I figured they were the same so that's why I decided to use it since it was OEM.
I had a 6p that bootlooped eternally couldnt access boot or recovery, I sent it in and they sent a new one. Board was damaged.
I also had a nexus 5 that bootlooped and it turned out to be a bad power botton. the internal connection was broken so it would get power and lose power all in the same second, off and on but too fast to see other than seeing a bootlooping device. that was fixed with a new power button which had to be soldered on.
if not on warranty you could take to a cell phone repair shop maybe they might be able to fix the issue.

It is under warranty, but the sad part is that I no longer have the receipt for it. I got the phone off Craigslist and the guy gave me the original box and receipt but I managed to lose it. I haven't been able to get it to fully boot back up again since last night. I'm not that worried about it anymore because I already have a new phone, but I wouldn't mind if it were to some how fix itself lol.

my first bootloop years ago i thought the same.
it wont fix itself. its not a software isssue because youd be able to at least boot into bootloader. it sucks to hear the truth but thats the truth.
its a hardware issue and you could take it to a repair shop because they will inspect and fix. small drops that dont harm the device can ultimately cause small breaks in the solder joints so who knows what is wrong without inspection

Nexus 6p - bricked?????

Hi all,
Hopefully this wasnt covered before- I used the search function and it didnt return any results, at least not for my specific scenario.
I've had this 6p for about 18-20 months roughly. Been my best phone by far, and I've been very happy with it(normally i replace my phones every 8-12 mos because I need the latest and greatest lol).
About six months ago I threw PureNexus on there with I believe Flash kernel. Worked flawlessly, and I've been really happy with it.
About a week ago, it powered off on its own but i had it in my back pocket so I just assumed it was an accidental reboot. However, this morning, I woke up, threw it on the charger for about 30 minutes, got to about 60%, and unplugged it. While I was using the browser, it froze up for a minute then shut down. No bueno. Cannot get it to power back on. No power light while charging. I did what others have had luck with, holding power, and/or power/down for several minutes, still nothing.
I reached out to Project Fi, and they want a 500 dollar hold to send me out a refurb replacement. I know they release the funds in approximately 12 days but we had a recent death in the family and I just cannot afford to have 500 bucks locked up, especially right now. Spoke w a supervisor, apologized, but said nothing they can do.
On a whim, I plugged it into the pc, and it DOES detect it but its the dreaded QHSUSB_BULK under 'other devices'. So that tells me its at least got power, but, I'm unsure if just trying to use adb(i havent in a while, not since i did the initial rom install but im sure i can find instructions) to attempt to throw the base image back on there, will work, or which direction to go.
I found this but I dont think its for my specific phone but thought maybe there was a set of instructions for this particular phone similar to these:
https://forum.xda-developers.com/nexus-6/general/fix-fix-qhusbbulk-cm12-t3059518
I have seen several reports of this error happening when flashing the wrong rom, or using the wrong image, but never just all of a sudden when its been running like a champ.
any thoughts? thanks in advance.
Nexus 6p is plagued with issues like shutting down at certain percentages and the dreaded bootloop of death. You could get in contact with Google heard even people out of warranty having success. Could also have a shop replace the battery in some cases that fixed the shutdowns.
If it doesnt boot up at all I can't help you. If you can get to bootloader, flash stock image, un-root, re-lock your phone. see if it boots. I had to do all this, this morning. Phone would just shut off at 80%, reset and hang at the google sign. I could only get to into the main system with a hard reset every time. then it would reset and lock up. So i reverted it to stock and we will see how it goes. So far its been 6 hrs and no random resets and its in full use.
Yea, the problem is, I cant. Its not even a boot loop. Just looks like its dead. Held the power button down for roughly 10 minutes out of desperation.
The odd thing is, if i plug it into my pc it shows how i mentioned in my initial post. So it must have juice even though the power light/etc isnt on and it doesnt show charging.
Last hope I think i have is to run it out of battery leaving it on the table, then hope somehow when i plug it into charge, that resets it somehow since it was dead, and maybe clears whatever the issue is. Very odd considering it was working fine until this.
Your phone is stuck in the EDL mode when its detected as QHSUSB__BULK. There are solution for this but i dont know if this solution is combined with data loss or not and i try to find that out recently. I also still dont know how to fix that with linux.
Here two howtos:
