Galaxy tab 2 7 P3113. Actual ROM: pacman based on android 4.2.2. ROM used when it first failed was a 4.1.2 stock based rom for P31xx).
i never dropped the tablet. the problem started after connecting to the pc for transfering photos.
it simply shutdown on connect and when this happen the device stay off even when i use the power button. cant use recovery or go in download mode. the only way to start the system is to use wall charger and the recovery or download mode buttons when the batterie icon started to show the charge animation. the date and time reset. i can disconnect the charger and use the device for some time but can randomly go black (no power) and the same thing happen... cant use power button or go in recovery or download mode. when the device work i can shutdown, power up and reboot normaly until it happen again.
seem to be a problem related to battery power. the battery charge and keep charge like it should, can be a problem between the battery and the board or maybe a failure of the board itself. (i know date reset on pc because there no power to keep in memory. seem to be the same on this tablet.) sd data is fine. i ask here in case it can be solved by other way than returning the device or open it.
was using a custom rom when the problem started. i tryed some other rom with full wipe with no effect.
i have seen similar issue but in my case the battery actualy charge to 100% and keep his charge normaly.
any idea how to fix this? if the only option is a return to ssamsung for repair i would like to know the step required.
note: when it fail and the device is connected to pc i ear constant connect/disconnect sound from pc and it look for omap4430 driver.

ok , another thing... i tried to connect it to my pc this time it work and i was able to transfer stuff to it. i unpluged and pluged again, no failure... the only thing i did was a few gentle tap on the back of the device to see if it was related to a bad connection to the battery. i also did a factory reset. will see if the device can stay unconnected without failure. anyway i have to wait for samsung reply.

Hi mates, yesterday I've made a change for 7 inch galaxy tab 2, 8GB, more specially the p3110, as well as I rooted it and updatet it and about 6am insomnia makes me take the tablet, So far so ordinary ...
well then turn it on and tells me that my sd is empty Nothing, I lost the data and I am about to make clear the sd, pretends to format and passed 15-20 secs it power off.
I get out of bed and went to connect it to the wall charger, knowing as sometimes if you leave the battery holding power and swiping your finger across the screen some time reappears stack and reloads it, I do it today that should have full charge and nothing, doesn't returns, when I connect it usb pc and when I do turn on the tablet it sounds windows connected usb sound and at the second connecting it disconnects device again, and there will end up pressing the button again
I removed the back cover and I have even removed the battery about 2 hours, reassembled and still doing the same ....
Summary: Does not display anything on the screen and battery charging even having tried the method "samsung" when this happens, (which only have it, with its official android I had to do it once, and recalibrate the battery even reach 4000 and mark its 100%, hence looked last longer and it was when the update and was working fine about 3 hours with it, no problem opening emails looking face and such, nothing out of the ordinary, there is no heat either, doesn't gave any fatigue sign and the battery was at 80% when It turned off suddenly), when you turn the computer connected to the usb nothing still while connecting a second and off the next, only once, until you return to try give the power or any combination, whether recovery, download, nothing shows anything on the screen
however when I connect it to pc to it hears something in windows, that tells me that the board is not dead, and the lcd was working ok and absolutely have any shot.
can you think of anything? I'm already crazy with this ... odin doesn't sees it, that connects the second and still sounds the little sound of I connect I get disconnected every time you try to pull it out, hopefully a recoverable semibrick at home or less silly ...
still nothing??

GENERAL CHAT!! All XDA'ers Welcome (noobs included)

ask your problem in the above thread
and dont make a whole thread buddy....try keeping the general section clean
I have a Samsung Galaxy J7 and there is no ROM on it. It had TWRP installed and working, but today it stopped booting. If I push the power button
nothing happens like the battery is dead. I went ahead and bought a new OEM battery and put it into the phone. I plug in the charger and for a
few seconds, the black screen shows a battery in the middle with a lightning bolt. Then it goes back to black ... I let it charge overnight but when I
go to turn it on, it still does nothing. no matter how long I hold the power button, nothing happens. I tried power + home + Vol and still nothing.
Just a black screen and no LEDs light up. Nothing ... if I plug it back into power the battery icon shows again in the middle of the screen with a
lightning bolt, then goes back to black.
What could this mean ?? Is there anything I can try ? the phone was booting into twrp just fine until today.
Please help !!

Flash stock rom latest with odin
Charge the batteries outside of the phone, with a standalone charger first.

Mmm ok I can try, I am very new with this phone, but have much experience with Odin and flashing, could you please point me to
the Stock ROM I should use?
Will this one be ok to try ? https://forum.xda-developers.com/galaxy-j7/j700t-development/rom-optimum-stock-v1-fullofhell-t3701168
Thank you so much ...
PS...( dodo224 ) I do not have a standalone charger to charge with so I can not try that method of charging. I will try Odin tho.

I dont have that phone so cant suggest you any roms, just make sure its stock and latest. Also i doubt that its a battery issue as a brand new battery has some charge which should have turned on the phone when you tried.
you can download your stock rom here: https://www.sammobile.com/firmwares/
download the latest one.

Hi -
I am a bit confused ... how can I flash anything if the phone will not turn on ? I can't even use Odin. If I push the power button on the phone
nothing happens. The only action I ever see is when I plug in the power cord to the phone, for about 5 seconds a big picture of a battery
with a lightning bolt through it, then the screen goes black again.
Thoughts please ???
Thank you
PS. I have tried different chargers and different batteries, but still the same result's.

Since you're new, have you tried pulling the battery, putting it back, then holding power, home, and volume down buttons simultaneously? It wasn't clear if that was the problem with using Odin or not.

If you have usb debugging on, there might be a way to reboot system in download mode. Its tricky But it works i guess. Try to Google some thing about soft brick. Im busy with work so not checking xda quite often. Sorry and good luck

Hi again -
first off Yes I have tried power-vol-home but again nothing happens. No screen. Just black. The ONLY TIME the screen comes on is if I put the charger into the phone..the screen ONLY comes on for 5 seconds displays the battery and shuts OFF. I have NO ROM / NO TWRP. . it is all gone. I had TWRP but if its there I cannot boot to it. No fast download / download / recovery nothing happens, only the battery ICON for 5 seconds. I have tried three batteries and none of them will help. It will NOT charge either.
Also Sandeepkumar - sorry I was not clear. There is NO OS. No Rom. So there is no way to turn on usb debugging. Please help ! If you have any other ideas, or you need any more info from me
Thanks again all !!
PS... Just so you all know, It was ALL working prior to this. It was rooted/TWRP/Custom ROM ... all fine. Then I deleted ROM/OS by mistake from TWRP, then this all happened

right, so now what we need to do is , connect your phone to computer while the device manager is opened on it. that way we can check if computer recognises the device in any mode. if it shows something in usb section then maybe we can look for a way to bring the phone in download mode or some other mode.

Okay, we must not check this pc for the device, open device manager using windows + X. Then selecting device manager from that black menu that pops up. Inside device manager, look for the list of usb devices, it should be near the end of list. Now when you plug a usb, you either see usb mass storage device or you see unrecognised device. Check what happens when you plug the phone and battery sign shows up

Okay, so if the phone doesnt show up in device manager then i guess there is nothing that we can do. I have ran out of ideas. Maybe its time to send it to customer support.
As you're trying all this, is your battery fully charged?

Oh ... Well I assume it doesnt show because it is not turned on. I guess my only option is to get a standalone charger and charge the battery then try again ,,,
Other than that .. IDK.
thanks anyway .

I hope you get the device working. Good luck and please share what happened.
FYI I charged the battery in a universal charger, now phone boots fine. Battery was just too low to take a charge from phone.
Thanks again
Hello there,i am new out here and my native language isn't english so i am saying sorry by now.
My A7 2018 rested on my desk,with 10% battery,and suddently the phone shuts down.It has happened to me before,but somehow i was able to turn it on and didnt have problems since.
Sometimes the phone's battery ran out fast when it was like 30%.
I plugged in the charging cable and it showed me a charging-logo-like thing but i cannot post any links here since i am new.
I thought i drained out the phone's battery and i let it rest and charge for like 30 minutes.
I did a force boot thing where u hold the down and power buttons for 20 seconds but nothing happened.
Sometimes the phone turned on but closed back on at the booting where it showed powered by android.
I plugged in the phone into my computer and into device manager at other devices it showed me exynos7885.Usb debugging is off if that helps.
I called samsung support and they have told me to bring it in for warranty at my phone carrier where i brought it from but i can't bring it in because it is scrached and the camera back glass is cracked so it dosent meets the requirements for my warranty.
I have all my photos,phone numbers,conversations and passwords on it so please help because i didn't back them up!!!(lesson learned)
Please help!!!!
Try reflash stock rom with odin. As you cant get into download mode. You may have to use fastboot to boot into download mode.
its so easy, go to odin mode and make sure that you've already downloaded the stock rom and use odin for flashing. If you dont know how to use just search it on youtube or here in xda for guide.
