Just wondering if someone could maybe point me in a direction. Maybe the tablet has died just find what I discovered recently interesting and wondering if makes it recoverable or still rubbish.
So the tablet seemingly doesn't function screen stays dark, no sound etc. Pressing the power button for a minute doesn't do anything, not sure which side of the volume button is down and tried both combinations but pressing the power button and one of the volume buttons doesn't seem to do anything either. Was about to put it into the bin when I decided to connect to my windows laptop and noticed that when connected for a short period it comes up as a com4 device.
Grabbed ADB but neither ADB or fastboot recognises. Any thoughts?

I have a rooted kindle fire running CM9. I installed words with friends, and tried to log in via Facebook. The fire locked up and doesn't respond to the power button, or to a usb cable. I guess my only option is to let the battery die, but does anyone have any thoughts?
Press and hold the power button for ~30 seconds.
Worked, thanks. I tried a long press, guess it just wasn't long enough.
I'm taking a look at my coworker's Nexus 7 (non-3G model), and it's exhibiting some peculiar symptoms. The most obvious is that the power button was jammed - I popped off the back cover and took care of that. The button has an extremely soft touch now, but it seems to work fine.
It was also booting itself up in safe mode. I figured the jammed power button was causing some weird power cycling, and the filesystem had been corrupted in some way. No sweat, just flash the 4.4.4 factory image.
Still booting in safe mode every time. If I turn it on with power + volume down, I get the usual bootloader menu, and all three hardware buttons work for navigating the menu. Then I continue past the bootloader and get into Android, and it's in safe mode, and the volume down button doesn't seem to respond (though power and volume up work).
Rebooting the device with the ribbon cable for the power/volume buttons disconnected from the motherboard still lands it in safe mode. So I'm pretty sure it's not a stuck hardware button.
For good measure, I flashed TWRP, fully formatted all the partitions, and reflashed again. Same deal. Now I'm running out of ideas. Does the N7 have some kind of auxiliary volume button inputs somewhere that are jammed/shorted, and which the bootloader doesn't look at, but Android does? This is what I see in adb logcat:
Code:
I/WindowManager( 483): SAFE MODE ENABLED (menu=-1 s=-1 dpad=-1 trackball=-1)
I can upload the whole logcat somewhere if anybody is curious/bored enough to look at it. I couldn't find any interesting errors in it, though.
So I left my 6p on the roof of my car, drove for about 2 miles and it flew off the car and was run over a few times. Aside from the screen being completely destroyed, it technically still "works" in that I was able to locate it via GPS with android device manager, haptic and ringing still work and the device is recognized by Windows when plugged in via USB, but without mass storage access.
I don't think I enabled USB debugging because it doesn't show up when I run "adb devices", but I'd like to try to get the device into recovery mode so I can get ADB or fastboot access and make some backups. I'd like to use the power / vol down button combo and try to drive it blind to get to stock recovery, but holding power down for 8 seconds just reboots the device.
Does anyone have a clever way of completely shutting the device off without having access to the touch screen?
disconnect the battery...

It works if you hold down volume down button just before it boots after holding down power button for so many seconds.
You could also wait till it goes flat and turns off, if it charges that is.
Hello guys,
Hope someone is able to help here.
I got Yotaphone 2 YD206 to my hands. It has problem with front screen staying always black. Rear screen says "Turn over the phone to set up". Cannot do it as front screen is always black.
Volume buttons work and power too. Also the phone rings if someone calls me. I can shut down long-pressing power button but device always restarts. I cannot enter download neither recovery mode. Power + VOL down or power + VOL up always reboots the device back to "Turn over the phone set up" -screen (text in rear screen).
I have flasher and Lollipop firmware files. But flasher says <waiting for device>. For me it seems issue with drivers. I have tried several usb drivers (WIN10 laptop) but still no luck. ADB devices command doesn't show any devices connected.
Any ideas? I believe someone might have a trick I have tried yet.
Thanks in advance!
Edit. After fighting hours and hours with flashing I decided to open the phone and found it was just simple hardware issue. LCD flex was disconnected...put it back and phone is alive.
What happened, I went through the airport screening (MCO Orlando). My tablet was on and functioning properly. As soon as I get to my seat, before I board the plane, my tablet did not turn on. I tried all the buttons (power, volume up, volume down) in all combinations and nothing. My tablet is dead. I'm pretty sure the x-ray machine at the airport shorted out the tablet, or killed it. Is there anyway to revive it? Aside from RMAing the device.

This worked for my death Asus Z300M:
Unplug device. Hold down power button for 60 seconds and then let go of it. Plug in the power cord. Now hold down the power button a few seconds and it will (should) come on.
