I installed the AOSP JELLY BEAN 4.1.1_r1 (http://forum.xda-developers.com/showthread.php?t=1765288) the other day and it was working fine. The problem is, I used it too much and the battery died on me. Fine. So I plugged it in to my pc via usb to charge it up. The Kindle fire boots to the TWRP triangle and then instantly shuts off. Well I thought maybe the battery is just really drained so I left it plugged in and went to work. Got home and it was still doing the same thing; boots to the TWRP triangle and then instantly shoots off and repeats. I unplugged the usb and tried using the outlet charger; same thing. Disconnected and tried to turn it on and nothing happens.
Figured I maybe bricked it somehow (even though i didnt update, delete, wipe anything). So I tried using the unbrick command lines...nothing. Tried the KFU cant find my device since it shuts off every 2secs.
I cannot figure out whats going on. Any help is appreciated. Thanks
Plug it into the charger and hold down the power button until it shuts off. Then wait for a 2-4 and check back on it.
Once it boots back normally make sure to update FFF and TWRP.
That didn't work. I plugged it in with the ac adapter and it wouldn't allow me to turn it off (i plugged it in then tried to turn it off). I let it sit for 8hrs and still boots up to the TWRP logo and instantly turns off and wont even turn on without it being plugged in. Thanks
Hold the power button down for 1 min it should shut off
it still does not work
Please post here some detailed instructions to turn on this device.
I'm tired of holding on and buttons in different combinations.
Sorry for bad English
If you have fff 1.4 a there really is no magic combination just simply power it off and plug it in via usb to your computer. If you do not have fff 1.4a then look here http://forum.xda-developers.com/showthread.php?t=1623244
Did u leave it to charge overnight.. cos i also had the same problem, which i primarily due to low battery charge..
Connect it to the charger and let it charge if possible overnight.. then try switching it on.. it shd definitely work

So I installed Greenify last night, I have no idea if it has caused this but it was the last thing I did before my phone went kaput so I am working on that theory now. Last thing my phone did was have the bar "Greenify has been granted SuperUser" or words to that effect and then hung. I tried a reboot at this point by holding down the power button for 10 seconds, screen turned off but phone did not reboot. From that point my phone has been completely unresponsive.
The phone registers as there when plugged into my PC, but doesn't show up to move files to/from. Also when plugging in a UTG cable the phone powers external devices. I am thinking at this point of running the battery down till the phone HAS to switch off and then plugging it in and seeing if anything different happens. Any other advice would be appreciated.
I have encountered this when I tried ART instead of Dalvik. if you use ART, I would suggest you try Dalvik.

My phone did the same after installing the Root companion for GSAM battery monitor. Like you said it at least responded when the usb cable was plugged in. So it was fortunate enough that I could just open the command prompt and reboot the device with adb commands.
adb reboot
You can restart your phone manually. Press the vol up and power button together and hold until the phone reboots. It will take a while so just wait.
I know there are already a LOT of topics concerning this - I have read through them all frantically, trying to find a solution before turning to asking myself.
So, here's exactly what happened, and what I've tried.
My phone was just fine, running perfectly, nice battery life. I had been running CarbonROM for about 2 months, without any issues, didn't change anything recent to this problem occurring. So one night I was at a party, and didn't have an available charger, so my phone ran out of power completely. The next morning when I came home, I set it to charge, the LED lit up, as far as I remember at least. In the evening I turned it on, and I got to the SIM pin-code unlock screen. I entered the PIN, and my phone turned off. No crash screen or anything, it just went straight out. I figured that maybe it hadn't charged properly, so I let it charge for a few more hours, and then tried again - same thing happened. I instantly tried to turn it on again, but this time nothing happened at all. I held the power button down for at least 1 minute, to no avail. When I put in the charging cable, the LED doesn't light up.
So, as I said, I have been reading around on this forum and other places, trying to find a solution. Some people said holding down the power button and volume up and down at the same time for 2 minutes would fix it, it didn't. I have tried several times. Most recently someone said I should connect my phone to my PC with the USB cable, and then hold down the power button and volume down. This time, something did happen. But not on my phone's end. I have done this 2 times, with the same result. At exactly 7 seconds, my computer turns off, as if I had "choked" it by holding down the power button on the PC. This seems really odd to me, since the phone can't even turn on, so I don't see how there can be any connectivity.
I hope someone here has a solution, knows why it happened, or can at least guide me in replacing any part if needs be. I hope not, though.

Should I just send it in for a repair? I have an idea that doing so will be very expensive...
Hello everybody. The story goes like this
Last night I put my P6-U06 to charge overnight, After half an hour I realized it didn't charge at all. Not even 1% although the device stated "Charging(x%)" on the homescreen. After fiddling with it a bit changed chargers, changed cables etc. the phone died. Putting it back in the wall socket started charging my phone. After a 15% charge I thought I boot it up. Then the display went completely black and started vibrating continuously. As such I believed it to be a software issue and proceeded to download firmware from the huawei website and placed it in dload folder in sd card.
Problem is I have absolutely no idea if the phone is off or not because as soon as I plug it in a computer or wall socket it starts vibrating and the little LED starts beeping red. However when I try the 3 button hold for recovery the continuous vibration stops for a second and then it kinda pulsates( like when you are typing ) then starts vibrating continuously again. I have tried every possible combination of these three keys all with the same result. For some reason I cannot start the huawei recovery procedure. Also the pc is not detecting the phone at any stage.
What do you think is causing this? I can't explain what happened. A minute was working fine the other bam! bricked phone.
Update: plugging the phone in the pc or wall socket while holding the 3 buttons starts it with the pulsating vibration mentioned above. However nothing on the display and a few seconds after releasing the buttons the continuous vibration resumes.
Update 2: This morning the phone was left without charge. When connecting it to the charger the display came alive with the battery and percentage of charge. However booting it again resulted in the same issue.
Hey guys,
Appreciate it if you could spare me some advice on how to proceed.
So I was watching a twitch stream and all of the sudden tablet froze, and the audio froze as well causing a large super high pitch noise, I hard-reset the tablet but instead of resetting it just turned off, I started to browse the forums and found that a combination of (POWER + VOL UP & DOWN + HOME) would reset the tablet,now what this did for me is turn the tablet on but it was stuck in SD CARD Mode, back again to the forums, read that letting it discharge fully and then it will be able to be charged and turned on, that worked tablet was back doing some various tasks no video again and then boom freezes again same symptoms except this time I couldn't get it to go to SD CARD Mode its very finicky after trying at various times in the day I finally got it to work, same process except this time as soon as it turned on I went into recovery factory reset it to stock, worked a bit longer this time only installed chrome, and it froze again (don't think it was chrome) , rinse repeat and I flashed the latest firmware with ODIN worked fine, I've gotten to the home screen ran through the "factory new" set up and it turned off of me again.
I plugged it in let it charge, came up with battery icon 5% 10% ect, then I left it for a while, I came back and I cant even get it to show the battery percentage(tap power) let alone turn on.
I'm fairly sure that eventually I can get it turn back on but from there I don't know what to do.
TL;DR - Tablet Froze, Hard Reset, Froze again - Rinse Repeat, ODIN to latest STOCK firmware, tablet worked for 5 min before turning off again (plugged in), present situation
Any ideas as what to be causing the freezing and how I could remedy it?
Also sometimes when it froze it turned itself off without me hard resetting it.
Thanks its been driving me insane,
Please do not hesitate to ask me to clarify or provide more information so I can help you help me.
Maybe youve got the loose battery connector problem?

What would you suggest I do, submit it to warranty ? Will they disregard the fact that knox has been tripped if its a hardware issue ?

I had the loose battery connector problem, but the symptoms do not sound the same as mine. I could get mine to boot up, but the screen would flicker and a few white lines would appear before it would reboot itself. I actually started a ticket with Samsung and got the packaging label but, upon further reading, realized that I was pretty much SOL after tripping knox, and didn't want to risk the chance of getting charged for just sending it in. If it is indeed the loose battery connector, you should be able to remove the back cover yourself and fiddle with it. Ultimately, mine needed re-soldering, and I was able to find a local electronic repair shop to do it for me for cheap.
Good luck!
UPDATE: I've managed to get into SDCARD MODE yet again, except discharging seems to get out of it, but once I plug it back in it doesn't come up charging it just black screen, until I hold some buttons and arrive back at sdcard mode. Good times.
Trying various things to get it to boot..
EDIT: Appreciate the insight Squez, I want to exhaust all the other options before opening it myself, if Knox didn't void the warranty to some degree, opening it up should put the final nail in the coffin.
EDIT2: Good news, sort of, tablet isn't dead! after numerous attempts with charge SDCARD mode, discharge, It finally start to charge properly and I managed to get it to boot, worked for a few hours then I left it to charge, and went to sleep, woke up and wont turn on again, but I am in SDCARD Mode again but need wait for it to discharge from presumably 100% ....
[What do you mean Sd card mode? DOWNLOAD mode?
Also no need to let the battery drain.
Just press VOLUME DOWN(not volume up) and POWER together then hold until it restarts.
This is a hard reset and will ALWAYS work unless the device is hard bricked. It is the equivalent of a battery pull.
I continually see here and there incorrect information regarding key combinations, even in so called guides, this forum is even guilty!
Here is what works on the 10.5lte, as far as I'm aware its the same for all versions, indeed pretty much any Samsung device.
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
DOWNLOAD MODE:
HOME - VOLUME DOWN - POWER.
Hold until the device boots.
RECOVERY MODE:
HOME - VOLUME UP - POWER.
Hold until the device boots.

I should of posted a photo earlier but here is one I found on google of same screen: (check attachments)
Except UP KEY and DOWN KEY don't do anything, its just this screen, if you attempt to hard reset ect, it will just reload this screen, hence the discharge, then plug it back in and hope it begins to charge "battery icon appears". I have gotten it to boot like this a few times.

Yeah its strange as.
I'll have a look at that, thanks.
EDIT: It just finished discharging and now I am on the battery screen.. Usually once it charges here I can get it to boot, what I'm curious is what on earth keeps causing it to freeze up, because in download mode and twrp (gone since i flashed stock via odin) it wouldn't freeze at all, only have issues with it once its booted or charging. I installed a logcat earlier hopefully that should shed some light on the situation,
EDIT2: Well another very interesting thing, the official Samsung charger wont charge it, only works if I plug it into pc or use a non-official charger, strange thing is nothing is wrong with the samsung charger or cable since I can charge my phone fully from it. These have to be some of the strangest symptoms.
EDIT3: Only works through USB port on PC for now, non official charger comes with red X on battery once booted. I assume you can work around this once rooted but that's for another time..
EDIT4: Charge through pc to around 2-3%, boot device, plug into official samsung wall charger and it begins to charge properly.
EDIT5: Hooray back to step one, trying get into SDCARD Mode, same thing happened left it overnight and it wont turn on or charge anymore.

i am pretty sure the HOME - VOLUME DOWN - POWER. puts the 10.5 into the sdcard mode.
my tablet is doing very similar to sunb3ar findings.
have had it come back to me once from sdcardmode.. (let if go flat and starting charging then it would start via normal buttons)
it crashed not long after that. it got stuck in sdcard mode again, but this time none of the drain flat, put on charge has worked.. just blank..
fyi- we try to put it in RECOVERY MODE, but it does not work when in this crashed / sdcard mode state
i even disconnected the battery and then plugged back on charge.. nothing..
today i tested the battery volts, 2.8v , for a 3.8v i thought that was ok. i attached my RC lipo multi charger set to 1amp 3.7volt charge, direct to the - + on the battery- got it up to 3.5v, plugged back in, put the charger on- the sdcard mode (most life it has shown in a week).
still not coming up with 'battery' display to say its 'turn-off and being charged'. just the sdcardmode might disappear and return..
i am currently adding mode charge to battery... will try to HARD RESET next.. since i have not tried that combo yet..
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
edit: i took it off 'direct' charge, battery at 3.7volts.. then plugged in normal charger, i got a 'battery symbol' but it had the lightening bolt, not a %.. so i unplugged and reconnected to my direct charge to give the battery more volts. i am surprised that the unit seems to think a battery with 3.8volt as it specs seems to not be like with volts not much lower than 3.8.. could be time for a new battery if we can get this thing to restart
