[Q] Refuses to Boot, No Lights, No Bootloader, QH_USBDLOAD - Nexus 7 (2013) Q&A

I've had the normal random crashing infrequently, but as of yesterday my Nexus seems to have bricked itself.
I placed it on the table after reading a chapter, and finished my lunch.
I picked it back up, and it was surprisingly dead, what with it's 3/4th battery and all.
I've tried plugging it in, mashing every button combo possible, one minute long press on the power button, holding every button in combination for minutes at a time, and every combo of charging/connector possible.
The only thing I've managed to get out of plugging it into a computer is QH_USBLOAD as the device identification, but, oddly enough, if I hold the power button down on the device while it's plugged in, the computer gives me a noise that would indicate that a driverless device was actually being restarted/removed/replugged, meaning it's actually doing something even if the device isn't indicating it.
Got any tips? I'm about to get a replacement, I think it's bricked itself.

Hold the power button down for 60 seconds.
If you do too many button combinations, it sometimes goes into the Qualcomm bootloader.

That was one of my first tries.
Nothing.

I've seen it on units a couple of times. Between holding the Power for 60 seconds and holding Power+VolDown for 30 seconds, eventually it comes back.
Plug in the charger and let it sit for 30min also.

Nexus 7 (2013) Power button and booting problem

Long story short, 1 month ago my Nexus 7 (2013) got water damaged, I immediately covered it in rice and left it for a couple of days, and after turning it back on, have a weird issue.
The power button will not work what so ever, I've tried holding it in for over 60 seconds, aswell as holding in the volume buttons along with the power button.
The only way to turn it on is to plug the nexus into the mains. I then get the white LED flashing 5 times, which I assume means it's charging up from a completely dead battery.
After about 20 minutes of charging, the google logo will pop up, stay on for 3-5 seconds, then the unit will reset itself (screen goes off, then back on to the google logo, and repeats like that).
However....If i hold in the volume down button, it'll boot up like normal, everything works fine, but take your finger off the volume button and it'll reset and only boot to the google logo. Holding volume up will take it too the boot loader.
The issue is that at no point, (in the bootloader or once its booted in to the OS) will the power button work whatsoever.
I first assumed that the button was broken, and stuck to the ON position, so ordered a new button cable (which includes the power button, volume up and down, aswell as the microphone) but this hasn't done anything.
Wondering if anyone had any thoughts?

Tablet not powering on? Brick?

The device responds to any button presses with the image that says 0% battery. When plugged in long enough it stays on "Needs more power to turn on." It has power, it can continuously respond to button presses with that bright image for hours on end. Attempting to boot into recovery/download mode responds with the same screen no matter how long I press it. Holding the power button for any period of time while unplugged results in it showing the battery 0% and then going to blank screen a few times then staying on a blank screen while immediately responding to any other button presses with 0% battery. Holding it while plugged in results in an infinite flashing 0% battery logo that flashes on for a split second every few seconds. Help?
Something similar has happened to me.
I installed TWRP and CM11 on it a few weeks ago. It had been running fine. A couple days ago I accidentally let the battery run completely out. Now it won't charge or power on.
It doesn't appear to be charging at all, doesn't get warm like it normally would when charging. Pressing the power button does nothing now, first time I tried to power it on I saw the plug image indicating no charge, but now I get nothing at all.
I've tried holding the power button for 30 seconds (and longer). I've tried holding the power and volume down buttons together. I've left it plugged in all night. It seems to be completely dead now.

Hard reset fastboot is enabled

Hello everyone, my girlfriend is having an issue where her m8 won't turn on. We looked at it last night and put it on the charger (although we didn't expect it would be dead already) and then left it over night. Woke up this morning and it's still having the same issue. I tried doing both a hard reset and soft reset, just anything to get it out of this weird loop it's in. Everywhere I look for information on hard resetting it says you need to disable fastboot - something a little difficult to do if your phone won't turn on. Are there any other tricks or work arounds that maybe I'm overlooking? I'd prefer to stay away from 3rd party fixes if possible that will void the warranty as I don't want her phone to get rejected if we need to send it out for repair. The closest repair facility is a bit of a distance so I want to see if there is something we can do from home first.
Thanks!
Disabling the "fastboot" option isn't really necessary.
Although I'm not sure what "weird loop" means. If its actually doing a boot loop, and rebooting, then just hold vol down to enter bootloader.
Otherwise, if its just "stuck" on the boot screen, then hold power and vol up to force a reboot (hold for maybe 10 seconds or so); and the moment the screen goes dark, let go of vol down and start holding vol down and don't let go until you see bootloader.

My apologies, my terminology may be incorrect.
The display is not turning on. Holding power + volume up or power + volume down do not get the screen to turn on.
The instructions I looked at all say disable fastbooting before trying to force boot or hard reset. So that was my confusion.
I really appreciate the help.

Any charging LED when charger connected? Any response from computer if you connect the phone?
Leave the phone on charger (wall charger, not connected to a computer) overnight, and try the button combos again (also, try just holding power down, no other buttons; in addition to the button combos you listed). Try this with the charger connected, as well as without.
Some folks have gotten their seemingly dead M8's to revive with apparently random combinations of button pressing (often holding the buttons for a long time, 1 to 2 minutes) charger plugged in, etc.

The only reasons instruction say that, is that the phone either needs to be "real" power off, or a reboot in order for the button combo to go into bootloader (power + vol down) to work. When "fastboot" is selected in Power settings, it actually prevents a real power down (its actually just a sleep state). But if you reboot, it doesn't matter. A reboot is a reboot, it doesn't matter if "fastboot" is enabled. And Power + vol up is one way to force a reboot.
None of this matters, if the phone is not responding (screen not coming on) at all in the first place.

I did leave it on the wall charger last night and was playing with different combinations. I'm going to try plugging it into my computer when I get home. I'm not noticing any LEDs come on however which is what is making me think it's not a screen issue.

I recall reading that someone got a similar issue sorted by hold Volume Up or Volume Down + Power button while holding the phone under a bright light(proximity sensor at the front needs to be directly under light).
There was similar threads/methods on the old HTC One(M7) too that apparently worked. Don't know if it's just coincidence or what Might be worth a shot.
Edit: Volume UP OR Volume down, not both at the same time

Seems goofy - but no luck! Thanks for the input though.
Any other suggestions?

Have you tried holding Power and Vol Up button when the phone is pluged in?
Tri taking SD Card and SIM card out and start.
Have you tried another charger?

Tablet won't turn on / charge

Hi,
I've only had my Samsung Galaxy Tab S for a few weeks. Whilst on a plane the battery went to 0%.. no problem I thought as I'd simply charge it when I got to a power source.
However, when plugged in, nothing happens. No LED light, nothing on the screen. I've plugged it into a wall socket and via USB into a PC. I have held down the power button, home and volume down for a period of time, as well as just the power button and volume down.
Has my tablet gone kaput?
Cheers,
Titanium
I'd just let it charge for a while. It'll take a bit before it comes back to life if it was completely drained.
If you still don't get any response hold POWER + VOL DOWN.

Should it show any lights? It's as if it's not even charging at all.

If it was powered off I'd expect the battery icon to show.
Did you try holding POWER + VOL DOWN?

Yeah, tried to hold it down. No LED lights and nothing shows on the tablet. It's as if it's just dead.

There are no leds.
I know someone else had the same problem. They used a different charger and it worked.
Try that first.

I had this problem.
You'll have to pry off the back cover, remove the wire that connects the battery to the motherboard. (A battery pull, basically).
Keep it off for 30 seconds. Then plug back in.
Use ifixit for details about opening. Feel free to ask for more help.
Try this one.
1) connect the tab to PC
2) press Home, Vol Down and Power simultaneously up to a screen appears;
3) press Vol Down to cancel and reboot the tablet.
John.
Now there are a few things you can try...
First check your charging port for any dust or any foreign particle. There has to be a small gap between the base of the charging port, and the small slab above it. Carefully, using a board pin, try and push that slab a bit up, don't apply too much pressure, just enough to make it move slightly!
This can happen sometimes if you drop your phone.
Next, make sure your charger, and the USB cable are working fine.
Also tell me if you have any Xposed module for your battery installed on your phone!

Thanks so much for that.
This morning, I plugged my tablet in to AC charge before leaving for the day -- battery was at ~30% and all was well. This evening, I came home and the tab was stuck at a weird Samsung logo -- not the normal boot with colored ovals, but the logo surrounded by a moving star field, never seen before, and could not get the tab to respond, turn off, do anything. Tried many wacky suggestions found on the intertubes to stop/start it, including holding power plus touching the screen for > 30 seconds, none of which worked. Never would have thought your suggestion for download mode would work, but it did on the very first try.
I'd like to know how the tab got into that state, and what that star field logo is about. But at least it's working again, for now.
Thank you.
That's the normal lollipop boot screen.

Suggestions for things to try with bricked 5x

I was getting a notice on boot that said "Your device is corrupted and cannot be trusted," so I held down the power and volume down buttons to get it to fastboot mode. However, I couldn't get it to be recognized in fastboot on my laptop. At one point I selected "reboot bootloader" and the phone promptly shut off, black screen and completely unresponsive.
From that point on, I can't get it to do anything. I've tried holding power + volume down for 20 seconds and then plugging it in (as noted in another thread) as well as taking it apart and disconnecting the battery to see if that would reset it somehow. No dice.
Any other suggestions before I give up? Thanks very much in advance...

my device is for the most part of the time in qualcomm mode, but I managed to have access to the phone 3 days ago, installing apps & stuff, worked perfectly well until I had
the bad idea to try to charge it through the charger instead of charging it through my computer...
how I've done it?
I used the power reboot technic :
1) pressing the power button for 1 minute
2) doing nothing for some seconds
3) pressing the power button again for 1 minute
4) connecting the phone to the charger, the red light flashed
5) the battery icon appeared soon after
6) waiting for complete charge, phone rebooting
it worked once, so I suppose it can work again. fingers crossed.
