Oh wise ones, I seek your advice,
I left my trusty little sidekick the Nexus 7 2012 tablet off the charger longer than I should have and its battery has run all the way down. I did this once before about six months ago and a factory reset fixed it up. Wasn't too happy about having to reinstall everything, but those were my consequences. (We went to Disney and I stuck it in the room safe for a couple of days without turning it off first, whoops).
This time my only excuse was I switched around some wifi settings to try and improve the reception, which may have shortened the battery life some. In any case, after recharging I have been able to get the device to come back on, but now it's just in the reboot loop. Going into the menu and doing a factory reset did no good this time, it still goes into the reboot loop. Over and over and over again.
I tried going through some of the guides to reinstall the original image from the PC, but I can't even get the tablet to talk to the PC well. I'm not sure where the hangup lies. I tired a adb command to retrieve the serial number from the tablet, didn't get an error message, but I didn't get a s/n either.
I just don't know where to proceed from here. I don't think tablet is toast, I'm just lost. So any guidance would be appreciated. Thanks.
Tablet is a first gen 2012 Nexus 7 tablet purchased the first week they were available. Very much out of warranty.

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.

I've run into a problem with my S4. I'm rooted, and running Hyperdrive 15.
My phone refuses to boot quite often. Sometimes it will boot up perfectly fine and run for a day - day and a half, or it'll lockup and then refuse to boot up again, OR it will just not boot at all. My power button seems to be unresponsive, and the only way that I can get some action out of the phone is by reseating the battery in the well.
What I think it is, could be 1 of a few things, or a combination of them - i'm not sure.
Scenario 1: While playing with the Hyperdrive tweaks, my phone was hung after running the Zipalign tool for over 20 minutes and I had to pull the battery.
Scenario 2: I'm deployed on a ship currently, and I have my phone in a high-salt enviornment and I'm afraid that there might be salt corrosion inside of the power switch or the USB connection - shorting it out. I took my phone apart tonight and cleaned both items with isopropyl alcohol ( the switch itself on the main board ) but that didn't seem to produce any new results.
Scenario 3: I was recently rooting a Kindle Fire HD 7" for a friend out here, and I was dumb and didn't realize that I was pushing boot loader files that were designed for the Kindle Fire and not for my Galaxy S4. I have since tried to enter recovery, but with little avail. Download mode is also out.
A description of what my phone does when I reseat the battery: My phone will vibrate, the Galaxy S4 logo will show for 1.5 to 2 seconds ( same for download mode ) and if I hold the appropriate button, ' Recovery Booting.... ' will display as well. At that point, my phone will shutoff and the power button will become unresponsive.
If anyone can give me a bit of guidance on how to proceed to repairing my phone, I'd be super grateful.

This sounds like the most plausible reason.
You will need something like JTAG to really fix it.
Lennyz1988, thanks for the quick reply. Internet out here is slow at best, and sometimes unusable.
As far as your JTAG option, I believe that would work, except that I dont have access to that kind of hardware right now. Sending my phone out at this point entails a month of transit time on each side of the turnaround time required for someone to re-flash my phone, and I wholly believe that I can do this.
As an update to my phone, it will not charge the battery anymore. I'll use someone elses phone to charge my battery soon. If anyone can give me a direction to go as far as how to completely reflash my phone IF it turns on, i'd be grateful beyond belief. I dont want to believe that if I can get it to start up again, that it is a total brick and completely useless - if it turns on again, i need someway to push new boot loader files to it. Really hoping someone can help.
Thanks again in advance.
I've dealt with a few bricked phones in the past that have been a simple fix through ADB/Recovery, but this one really perplexes me.
So I get work, place my phone on the desk, and a few minuets into the day I see it re-boot out of the corner of my eye. It's not something to be expected but this has happened a few time over the 5 months I've had this phone so I think nothing of it.
But 5 minuets later its still looping on the Google logo. So hold down the sleep button to shut it down, still loops. The only thing I have done to this phone is unlock the bootloader through the command prompt and install a stock Nougat image straight from Google
Using the hardware keys I can get into the the bootloader, but that's it. "Recovery Mode" option sends the phone back into a loop so I can't reset the phone to factory (though ideally I would like to save the thousands of photos on the device) or enable USB Debugging as I can't get into Android.
I have Googles Android USB Driver installed, Windows 10 chimes when I plug it in, It appears in Device Manager as "Android Bootloader Interface" but I have not been able to get it to show in the terminal with ADB. I have also tried on a Windows 7 and OSX Laptop.
I am completely dumbfounded, any help/ideas would be amazing!
Thank you

Unfortunately @5.1 is right. The common denominator of the BLOD (many threads on this) is the inability to get into recovery mode by any means. ADB doesn't work unless in recovery. Without ADB you will not be able to pull anything off the phone. At least you are unlocked so you can try some tools and/or manually attempt to fastboot boot or fastboot flash a custom recovery and get ADB working, but chances are almost non-existent. Some ppl have been able to briefly get back into recovery on completely full charge, but it seems to start boot looping again shortly afterwards from recovery. Hopefully you were using Photos and synced recently. If you bought direct from Google, contact them even if out of warranty. If they won't help you or you didn't buy from Google, approach Huawei for an RMA.
I was in your situation and was able to flash the full stock image (flash-all.bat command) even though my device didn't show up on ABD--but maybe I just got lucky. I thought there was no chance it would work but it did. Some people reported getting out of the boot loop using Skipsoft's tool but most likely you will need to RMA the device if it's still under warranty from Huawei. Sorry to hear you have been added to this club. There are a lot of lemon 6Ps that die because of hardware issues (according to Google) and they clearly don't care because they never recalled the affected devices. I was hoping it was just the early generation phones but if yours is 5 months old that means the problem is persisting. None of these things might still be running in a couple years which is ridiculous for a premium phone. Makes you think twice about buying another phone from Google since they threw 6p owners under the bus rather than offering 6P owners a credit or something for their defective 6Ps. Good luck. At this point I think people need to create a class action suit against Google. That's the only way people got repairs or compensation from Apple the numerous times they pulled stuff like this with defective products. Why should Google get away with selling what they themselves admit is a defective phone?
Right I feel silly, knowing this I just couldn't resist trying to fix my "phone", so I've bought a S7 Edge from eBay from a trusted company with a 14 day refund which is good right?
We'll I couldn't rest as the phone was going into boot loops, i.e booting once every 5 times, going into the black screen of death with blue LED.(Had to wait for the battery to drain to 0%) https://youtu.be/K9T_UF-_5ho (Even though it booted at the end after a minute of use it crashed and went back into a boot loop and crashed and then it was fine for like an hour)
It would get stuck if I went to stock recovery, get this weird static line. I did boot into recovery once so I did a factory reset hoping it would fix something, which it did not. So I guess I was going to return the phone, I then had the stupid smart idea that it booting up fully and me activating it and then resetting it would be a good idea, and boy I was wrong. So it went to you know the usual "erasing screen" in which it would get stuck on, I did the hard restart maybe 4 times then it sorta worked the android guy kept spinning until IT JUST DIED.
And here we are now me typing this out, I feel like the company isn't going to accept it back due to it not being "functional".
Absolutely no sign of life now. Not even charging, this has happened before with it when I went into the recovery menu and it got stuck. I waited out an hour and then pressed ALL the buttons and the charging icon appeared but now, now I think it's different.
TLDR: Bad eMMC of phone, caused me to try to reset it and now it's bricked?
Well lesson learned? When things aren't working at the first place don't try to fix them just refuse outright.
Some say the phone can't be bricked but I feel like I really did it this time.
No the phone wasn't rooted, no I didn't flash with ODIN.

Just return it.
There is nothing else you can do and I see no reason why they wouldn't accept it unless there's a physical damage.

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.
