I've got one of those 10.5 models (SM-T807R4, the US Cellular version) that suffers from the screen freezing problem which requires either pushing the power button twice or closing an opening the case. In an effort to fix the problem, I rooted it and installed TWRP 2.8.5.0 and was able to successfully boot into TWRP. I backed up the boot loader and the system using TWRP and the entire tablet with Titanium Backup.
I just booted into TWRP and was ready to wipe everything and install a new ROM when the screen froze. I can't unfreeze it with the power button or by closing and opening the case. When I pushed the power button, it locked TWRP but since the screen is frozen, I can't swipe to unlock it. I tried the power+home+vol down sequence and that didn't work. I have held the power button down for a minute or two (until my fingers gave out) and that didn't work either. I hooked it to the PC but the PC doesn't see it so Odin or ADB or Fastboot don't do anything. The only upside to this is that now I'm pretty sure the screen freezing problem is hardware rather than software so flashing a new ROM probably won't help.
At any rate, I need suggestions to shut it down, given that nothing I have tried has worked. Then I'll see if I can sell it as a boat anchor!
================
Well, I got finally got it to boot with the power+home+vol down sequence. Will try TWRP again later.

I just flashed a mod for fixing the low auto-brightness on the GNex. Upon boot everything force closes. I did a nandroid backup before flashing, however, after a battery pull and holding down the volume down and the power button I cannot get into recovery. The screen that comes up says "Downloading.....Do not turn off target!!!". Pushing the volume up and down buttons do nothing. Pushing the power button just reboots the phone. Any ideas on how I can get into recovery?!? I'm starting to freak out.
Edit: After numerous tries I was able to get ADB to reboot into recovery. If you get stuck in ODIN, reboot the phone while connected to your PC. If you are able to get past the boot animation, do not try to unlock your home screen if you previously experienced numerous force closes. Allow the phone to get to your lock screen and then use adb to reboot bootloader. From there you can get into recovery. I'm sure this is probably a well known thing, but coming from the original DINC, I never had to use adb. This was a lot of stress and eventually a huge sigh of relief once I figured it out.
Hello everyone! So I've had my phone (HTC One M8) rooted and custom recovery and rom installed for a little while now. The latest rom I've installed was Android Revolution HD 22.1. I also have twrp 2.8.1.0 installed. The other day my phone got wet and started to constantly reboot itself, wouldn't shut off and stay off, would never actually start. I put it in a cup of rice for 2 days, then proceeded to plug it in to charge it. Once charged enough I tried to turn it on. It only made it the HTC One logo screen and would vibrate every 10 seconds or so. I tried rebooting several times and no matter what I did with different button combinations I could not get it to load into bootloader. Eventually with restarting different ways and "mechanically stressing" the phone (short temper lol) I managed to get it to loading into the rom itself. From there I opened hasoons all in one toolkit to reboot directly into recovery and recovered to the stock rom. So the phone will now reboot with no problem into this rom. I haven't tried reflashing the ARHD 22.1 rom again because im afraid it'll break again. However, while in the stock rom everything work fines except for the volume up button which does nothing, except for while the screen is off, if I turn my phone to landscape the camera app will open without me even pressing the volume up button. If I reboot into bootloader via the quickboot app or hasoons toolkit, my volume down button with make the cursor go up, the volume up button does nothing, and the power button does nothing. The only thing I can do in bootloader is to hold power+volume up to get the phone to reboot. I also cannot get bootloader to load by holding volume down+power. So, After all that explaining, my main question would be, do you think that the buttons are shorting in a weird way because of water damage, or do you think my software got corrupted because of all the rebooting it did? Any help is appreciated, thanks!

UPDATE: my power button will now lock my phone but not unlock it.
Hi
Could some one tell me why i cant get in recovery or factory mode with hardware buttons, i am on stock 10d with twrp recovery installed and rooted wirh super su through twrp. I installed twrp through adb with normal command and device works just fine through reboot apps from os, boots in recovery,fastboot etc just fine,same through adb commands.
But there's no hardware combo or anyrhing working when trying to enter recovery or factory reset working at all?
Tryied every combo i could find saying how to from internet.
It just boot up in os as usual.
And phone dosen't reset while holding power button for 10s + either
It's a bit scary because bootloop is going to come eventually for sure and then there's no rescuing avalible
Could someone plz tell me whats going on?
Im new to g4 so, some help would be nice.
Thanks in advace
It's a bit tricky, to be honest.
• Power off your phone
• Hold "Volume-Down" and keep your "Power-Button" pressed. So you should keep both pressed, until the 1st LG logo appears
• Now just leave the "Power-Button" for ~1 second whilst kept the "Volume-Down" button still pressed, press now the "Power-Button" again and keep holding it
You're now forced to deal with the standard-ui from LG. Go to "Yes" and again "Yes". TWRP now boots and you should be fine .
Edit: Just my tiny story... I watched several videos and also had a nasty bootloop. I was afraid, I now bricked my phone. But a nice user showed me this way and this was the only way, I got my phone recovered.
The first problem I encountered while rooting my phone was that TWRP wouldn't stick, even though I didn't choose read only (ie i allowed it to make system modifications on the first TWRP boot) after rebooting
and booting back into recovery I would boot into stock recovery, instead of TWRP. So I tried flashing twrp, booting into it and rooting the phone, which was successful!
THE ROOT was successful, TWRP still didn't stick, every time I want to boot into TWRP I have to boot into it via fastboot.
Getting to the main problem, I booted into twrp, flashed a custom rom and got stuck in a bootloop while rebooting. It reboots every 15 seconds, I have kept the power button pressed for almost 2 minutes it doesn't stop the bootloop, I tried other combinations of vol buttons and power buttons does nothing.
One weird thing is that while it's in the loop I just have to press the vol down button and it boots into fastboot (as opposed to both the power button and vol down) when I boot into fastboot it stays there for about 6-7 seconds before rebooting, I tried booting into twrp through fastboot, but before I am able to enter the decryption password to start twrp, the phone reboots.
Should I let it run out of battery? will that stop the bootloop? I have a backup in twrp but I can't access twrp!
Does anyone have a solution?
[update] I let it run out of battery and on charging it continued the bootloop, with great difficulty i managed to install stock img file but the device just wont quit the bootloop

1. Try flashing new recovery image using TWRP booted via fastboot.
2. Does your phone had contact with any fluid or was in place with high humidity level for longer time? Your power button is short circuited. In other words it is in pressed state all the time. I had same problem on my previous P2 when I came from 1h running session in light rain. Some sweat and/or water got inside my volume down button and same thing happened.
In my case the phone button recovered itself after drying and clicking it a lot of times

I can't access TWRP as the phone doesn't give me enough time to enter the password for decryption, which is asked at the start every time you boot into TWRP, I get like 5 seconds in TWRP before the phone reboots
It is possible that the power button is spoilt as I have sweaty hands...

That's the reason. I know that pain. You should try pressing that button with different pressure (but be careful) and move you finger while doing it. Maybe it will recover itself. If not you should find someone trusted who will open the phone and clean the buttons from the inside. It's a shame that Lenovo just left this construction vunerable like that.
After you get your P2 working properly again then just buy case that will cover whole buttons to prevent situations like this next time. Also make sure to clean it regullary inside.

Hi all, my Tab S 10.5 (T800) was running stock MM with no root. I tried using the Adoptive storage enabler patch from this site. After installing the TWRP using Odin and flashing the adoptable storage patch, I am stuck in that stupid reboot loop. I did selected "Allow modification to system partition..." in TWRP. I managed to apply the batch and after a number of attempts boot successfully, changed to internal storage etc but still getting random reboots all the time now. Read more on the site; then did cache clear, factory reset via recovery and then also flashed back stock MM firmware - everything successful but still getting random reboots.
Just to mention, the tablet has recently had a brand new original battery so that is not the problem. It was working fine before I attempted the TWRP/Adoptive storage patch or stock firmware flash and now getting random reboots (sometimes right at startup logos and sometimes soon after booting up).
This appears to be a very common one on these Samsung tablets so no clear reason anywhere why it happens. Any suggestion for a quick fix for this please. I am getting random reboots at the moment all the time since I tried flashing the recovery/patch/stock firmware. Any help would be appreciated please...
update
Just to provide quick update and info:
Purely by hit and trial, I have found that if I keep hold of the power button (pressing it constantly since power up), it goes past the initial boot loop consistently and boots the device up. But then, once it hits the limit for holding the power button (think 30 secs), it vibrates and turns itself off (which I think is normal behaviour). So I thought this is interesting to share as not something I have read anywhere else. Not sure what difference it makes to the startup by holding down on the power button but that does not appear make it loop. Of course, this is not a solution as the tablet eventually shuts down after 30 secs of holding the power button.
The power button itself seems fine and not broken/damage or anything - clicks fine and solid and works fine every time. Also the random restarts does not happen in recovery/download mode so I take it the power button is not faulty as else, it should be happening for everything.
Again, requesting everyone for some help please as I am a bit stuck what to try next.... thanks in advance!
anyone pls...?
Bump again... in the hope one of the experts will jump in to help!!
Thanks in advance
I'm experiencing the same exact issue, The tablet will power up to the setup screen and I can almost finish the setup process but then it vibrates and powers down. PLEASE... someone, chime in and help with this problem.
Thanks In Advance
