I was in TWRP recovery flashing Xron rom b2.9 and the recovery said the zip file cant open. So it just kept doing its thing and would not let me go back to the main menu. I tried hitting home and back buttons, but no luck.
This was not found by me. I am giving credit to this amazing person who somehow found a trick to reboot the device even if your not in an OS.
"The reboot solution that I found to work all the time is to simultaneously hold the power button, volume down button and the big HP button for 30 seconds."

I had an issue with my Touchpad where the touchscreen stopped responding in CM7. Volume rocker worked and power button would turn the screen on and off, but I was stuck with no touchscreen and no means to reboot. After a mild panic attack, I plugged it into my computer and luckily had debug mode enabled so I was able to adb reboot it.
But this... this is incredibly useful. Thank you for the post. I'm glad to see that the manufacturers making devices without removable batteries are giving us a trump card to hard reset the devices. My 7" Galaxy Tab has a similar function where holding the power button down for long enough eventually resets the device.
..or you can just hold power + card button for 6 seconds. no volume button needed.

Pretty sure I overheated the phone last night, and now the power button doesn't work. I fell asleep with it in my pocket, I got a call from my wife early in the AM, after the call I found the screen wouldn't turn off. So today, I've tried an app or two to replace the power button, tried a 3 hour battery pull, and in a brief instance of idiocy, decided to reboot into recovery to try and wipe everything and see if that would do anything - now I am stuck in CWM Recovery w/out any working power button so I cannot even exit. I've tried pulling the battery again and it just reboots into recovery.
Any tips on how to get it out? I want to pull my pictures and info, wipe the phone then sell it on ebay - What would I need to do?
if it is a custom recovery you can use ADB while booted into recovery.
adb pull /sdcard
Has anyone had a problem with just the power button not working at all anymore?
My SII had the problem recently that the power button just does not work, so I can no longer wake the phone up after the screen has shut off. I'm guessing it is a hardware problem because I even restored it all the way back to stock.
Does anyone know how hard it is to replace the button if it is bad?
I had my power button fail for several days on me (it has since started workign fine again tho). I was in a similar place but when pulling battery, my phone would reboot normally so i could at least use my phone while on the charger. I know that pulling battery, holding volume up/down and reinserting will boot you into recovery so i'm wondering if your volume button is messed up too? can you navigate up and down in recovery with the volume keys?
I had to get my button working to position myself to avoid the issue but I'm now pretty much power button free and running siyah kernel (touch recovery) and i use the Stweaks swipe to unlock feature, rootbox rom with a power menu toggle, and a lock screen widget so i don't have to use my power button at all. Again, i had to get my power button working to flash the kernel though maybe you can push the kernel with odin then you'll have the touch recovery to try wipes and resets with?
edit: here is a link of tearing down a 9100. I think our power button is the same- unfortunately it looks like you have to solder the new one in.
I couldn't find the part# for the i777 (or confirm if it's the same as the 9100) but the power button for the 9100 is KEY FPCB-POWER KEY(GT_9100) GH59-10916A and is about $5 online
here's a vid of the breakdown, he's replacing the screen but browses over the power/volume keys too.

Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks
So I had the OTA update for 5.1.1 the other day and thought "yay, let's update." it worked fine till this evening where it crashed to a power off state and in now showing the Google logo like it's about to load up and then a turned off screen.
This repeats over and over I can't even stop this loop.
Holding the power button and it just continues to loop.
Power + ANY volume button and it will show the HBOOT or fastboot menu then before I can select anything turn to the powered off state and loop through (if I'm still holding the buttons the menu will show again shortly, or go back to the Google logo)
Any ideas for a solution?
try waiting until the battery drains all the way down then hold the volume down button and plug it in. if that doesn't work then all you can do is contact google support and they'll probably replace or fix it.
Hold the power button down for 20 seconds 3 times. It helped me once with a similar situation
So I have found a solution. Instead of deleting the thread I'll leave this here unless anyone else has this problem.
It seems that trying to enter the fastboot menu when plugged into a USB seemed to work.
It was either the fact it was in the computer, the timing I pressed the "power button + power down" combo, or it had just looped enough times and decided to actually stop interrupting me using the fastboot menu.
Either way, I cleared the cache partition using the recovery and it booted up fine.
EDIT: Thanks for the help, I had tried holding the combo for a long period of time (multiple loops of the booting). I also feared letting it drain in case it refused to startup again and I would have no chance of fixing it.
glad you figured that out! android can be mysterious sometimes. especially when it's on the nexus 9.
Hi, I couldn't find anything about this issue here, on Dell forum there was discussion about it 2 years ago but it wasn't solved, but it seems that a lot of people face this issue and I'm honestly surprised no one talked about it here.
So I just bought this tablet, it's used but whatever, at 56% of the battery it shutdowns and there is no way to power it back on without connecting to the charger. Can't even access bootloader menu, it's just dead.
Has someone faced this issue and has any idea how to prevent this from happening? It renders the tablet unusable and I don't really want to pay the service for changing the battery if it's gonna do the same thing
Thanks
I got the same problem but no solution. The only thing I recognized, is that the tablet things it got 11.000 mAh instead of 5900 mAh. But why?

Found something:
Try the following and see if this resolves the problem. This is not a master reset so your information will not be deleted.
1. If your device is on, turn it off.
2. Press & hold the Volume down button. While holding Volume down, press & hold the Power button until the device turns on. You'll see the word "Start" with an arrow around it .
3. Press the Volume down button until you highlight "Recovery mode."
4. Press the Power button to start recovery mode. You'll see an image of an Android robot with a red exclamation mark.
5. Press & hold the Power button. While holding Power, press the Volume up button once. Then release Power.
6. Press the Volume down button until you highlight "Wipe cache partition," and then press the Power button to select it.
7. Press the Volume down button until you highlight “Yes,” and then press the Power button to select it.
8. Wait until the cache is wiped. You’ll see the words, “Cache wipe complete.”
9. Press the Power button to restart your device.
Worked with my venue 7840.
So the dog tried to eat the phone, thus the bottom part of the screen is dead so there are no software buttons to use.
Now where the problem comes in.
You go into TWRP to see if you can make a more resent backup but you can't see enough due to the strips on the screen and since the software buttons are gone you're stuck and it will lock itself and you can't even swipe to unlock. Since newer phones don't allow the battery to be pulled you're stuck until you run it down which will take days.
TWRP and any other recoveries should reboot when the power button is held down IMHO but obviously they don't. Few things are more annoying than something electrical that you can't turn off.
I found that if you hold down the volume up and volume down buttons then press and hold the power button it will force a reboot.
Forced power off is holding power down and power button: https://www.verizon.com/support/knowledge-base-215164/
This is also provided as a popup instruction when you first boot the phone after setup. So, there is a way to force it off, just not with a single button as you might prefer.
You may have found another option with the reboot process.
I can confirm this procedure worked on my Redmi Note 4 (MTK) stuck in TWRP after I executed "/sbin/recovery" from adb shell, which killed the touchscreen and USB connectivity (??). The standard way (volume down + power) did not work, but this volume up + down + power worked, strangely enough.
