I have a Galaxy GT-P5110 10.1 which has suddenly died ,no display ,no charge, nothing.I`ve tried all the usual resets, button pressing and even factory reset.
I`ve removed the back and disconnected the battery and connected a constant current power supply ,set at 3.7volts directly to the internal power conncector and this immeadiaately showed a current compsumtion of just over 1 amp.! which seems quite high and probably indicates a short somewhere possibly the battery control I.C ? The on /off button has no effect.Any body got any ideas before I start to look for a service manual?

I had my tablet for 2 days now but it all of sudden, the tab became unresponsive.
I was using it this morning and it went to sleep (I didn't lock it with button), and when I went back to turn it on, and that's when I found out it was dead.
the tablet does not respond to power button, charger or computer.
Anyone have a similar fault?
I can't believe I have to send this back to hk now for repair.
Have you tried turning it on to either download or recovery mode?
What is that mode?
I got it to turn on finally while tryibg bunch of random combos (volumn down + power) and (volume up and power)
etc
Try holding power button on for up to 20 secs worked for someone on the av forums
my tab every two days just freezes.... i have to press power for a few sec for it to reboot
Had a similar issue recently. When my device went to sleep it wouldn't wake 'normally' I could hear the volume up/down sounds but no picture. had to hold down for an extended period to reboot.
I checked what was using the most battery and it turned out to be "media" I had some issues w/ my ext SD card recently and noticed when I removed it all was fine.
so that was my solutions (as for why my SD card is giving me grief, that's anther yet to be determined issue) but atleast it 'wakes' normally and my battery doesn't drain like crazy.
I have the same problem - Tab go to sleep mode and death. Nothing is working. Have anybody idea what to do with it. I have only 1 idea - take it to service
Edit - Problem solved ;-) Conect Tab to PC while pressing VolDown. It start charging and after while you can start device.
I've got a similar issue. When you hit the power button to wake it from sleep, nothing works and you barely see the bottom taskbar. Reboot obviously fixes it. It happens pretty randomly every other day or so.
Hi , i was just thinking it may be of some help if you posted more info .
What ROM you are running .
What ROM you loaded before this one .
How you loaded the ROM you are currently running .
The reason I ask is that these problems may be ROM related and if thats so
you may help others to avoid the same problem .
Oh by the way , I have had this same problem show up with other devices and also
with computers not booting and it was caused by a SD card .
P.S good luck wish i could help .
hello,
I had left my phone to charge at night, then this morning it was not responding. Power button was not waking up the phone. Then i forced to reset by power and volume buttons. Vibrated 3 times and completely shut off. Now it is not opening.
I already tried, reset button in sim cards slot. It is not working also. Please help me.
Did you try connecting it to PC Suite or FLashtool? Check that once and also try charging another hour and then force reset the phone. Also I think there is a reset button somewhere under the sim card slot. Try that one too.
Hold volume up and press power. Wait for beep three times. Give it a few seconds and then press power alone, should boot.
Thanks guys, i tried both but still i have sudden death. reset button and power+volume buttons not working. Also flashtool could'nt find my device.
Thats not good, any led when plugged in?
I had a similar instance after flashing unofficial cm12. Phone was cooling down from taking a run through an obvious cpu bug that really killed my battery. I shut it off to cool down with 20 precent still left in the battery. And the phone started to act this way when I went to power it on. No led power indicator or anything even with usb connected. My computer did respond to the usb being connected as if a device was there though. I waited about 10 minutes with the phone in front of some cool air and then did the volume up power button reset which worked then. Still quite a scary incident.
I am on stock rom. Factory resetted after 6.0 update. Didnt tinker with rooting so far.
I have strange battery issue. Sometimes the phone charges very slow experiencing this after 6.0 update. Tried amper app from playstore. It shows form 70 mA to 1020 mA.
The second issue is power button. It started to restart the phone when pressing power button ( Not always but once in 2 months). I tried volume unlock which is a huge battery drainer.
I need someway to map it to volume button without any usage of app which wont let my phone to sleep. I am ready to root the phone for it.
UPDATE :
The charging issue was with the USB cable. New stock USB cable is able to charge it. Replaced power button from LG service center for 1000 INR (15 $)
Hi,
First I hope I'm posting this in the right place - to get assistance/direction that will help my situation. If not my apologies - please send me to the right place.
I have a Nexus 5, Android 5.0.1, Rooted.
- My device was charging then suddenly went into boot cycle - showing the Google logo then powering off and repeating the same. Trying to get into recovery mode was impossible - would power cycle out of there too.
- I have tried doing the multiple fast press, and sticky button clean solution (actually taking the back plate off etc.) posted out on the net but that has not resolved my issue.
- Left my phone to charge overnight. The problem still persists. More accurately. Turning it on without it plugged in to the charger does nothing.
All the following is the behavior when its plugged into the charger:
- Without pressing any button just shows a full battery charge icon for about 8 sec then the screen turns black for two seconds and that keeps on repeating. If I press the power button it shows the Google logo for a 1.5 seconds and shuts of, going back to the battery charge icon flashing cycle.
- Now if I press the power and volume down button It takes me to the fast boot mode screen where can cycle through the menu's <Start, Restart Bootloader, Recovery mode, power off>. None of the options work. No matter which I chose the phone shuts of and goes back to the full battery icon cycle.
- I was thinking a battery issue but, when in recovery mode the phone will not turn off. I can use the volume buttons to go through the menu as pointed above but using the power button just takes me back to the battery icon cycle. Now I'm not sure, battery, power button or software. What could it be?
I am thinking, try a new battery or, damn buy a new phone (my phone has outlived its warranty). If there are any ideas on fixing this I'll appreciate your opinions. If i have to get a new phone is there any hope of salvaging data. I have a 4 month backup on my computer, but my latest is stored on my phone.
Thanks.
If you run into this issue and none of the solutions in my original post apply, read on in case my final solution helps you out (you might not even have to get paid help if you know how to work on the fault I was experiencing). If not - nothing more for you to gain if you read on.
As it stands:
I took my device to a reputable cell repair shop. After describing to them the symptoms of my device the out ruled the stuck power button issue and tentatively diagnosed it as a firmware bug or nand memory corruption issue which would require a nand mem flash which they had the tools to do. I went for it.
When I went to pickup the device. They reported that the device was functional and they did not even have to do the flush. My data is safe. Issue was a loose battery contact which they detected and fixed. It's been 8 hours and all looks good. These guys were going to charge me a $80 bill to do the flash if the recovery was successful, but I had to leave a $56 deposit after tax for them to begin the work and pay the balance if the procedure was successful. When closing the deal they just gave me the device and said since they did not have to do what they anticipated, the deposit I left them was satisfactory.
I have my device back and working (at least for now) and have the chance to make external backups incase the issue reoccurs. I'm happy. Cheers.
My LG G Flex 2 H950 was working fine, running google maps and playing music, plugged in to the car charger. Within minutes of leaving the car the phone was dead - I could not power it on. I can usually get it to show the LG logo by trying to start in Recovery Mode (holding the power and volume-down buttons for several seconds) but then the logo just disappears after a few seconds and the phone does not power on. But sometimes when I try this the red LED blinks on the phone screen and the logo may or may not appear. Sometimes (50%) when I plug the phone in to my Windows 10 desktop, the computer plays a tone to indicate a new device has been connected, but no icon appears in the list of hard drives or devices.
I think the battery is charging normally - when I connect the phone to a USB volt meter it usually (but not always) shows a normal amount of amperage flowing, and just now when I tried to start the phone it showed the battery charge icon on the phone screen (it doesn't usually do this) and showed 100% charge.
Is there anything else I can try, even if just to get the phone running long enough to backup my text messages etc?
Is there any way to test what's actually wrong? I'd hate to spend money on a new battery or charging port etc for a slim chance to temporarily fix a phone that seems like it's dying.
Thanks for any advice or suggestions...
Hey, i've got the same problem since today. i was watching youtube videos when the phone suddenly stopped working. did you already find the problem?
Sorry for my bad englisch ( Dutch)
No - not solved, phone still dead. Still would love to hear any advice...
I used to have the exact same problem as you - bootloops at the LG logo, no recovery etc. After some reading it seemed that the battery was the root of the problem, and after replacing the battery my phone was back to life - no issues ever since. I recommend you check if the battery is the issue by connecting it to a normal charger (i.e. not charging from a PC) and powering it on, by holding the power button at the battery charging screen. If it powers on normally then it's most likely a battery issue, which can be easily fixed. Cheers!
