Problems with GT-P5100 - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hi and Merry Christmas to everybody!
My Galaxy Tab 2 GT-P5100 seems to be completely dead. The battery drained to 0%, the tablet stopped and never charged or started again. I removed the battery, charged it from an external power supply and put it back...nothing. Buttons are good, I checked voltage on capacitors as the service manual says on pages 24-26, everything good, but not starting.
Also, without battery it connects to computer as OMAP4430, so I tried what this thread says, but still nothing.
Any suggestions what I can do, please? Maybe the EMMC is fried?
Best regards,

Happy new year to everyone!
Does anyone have any idea what can I do?
Actually, it's charging the battery but does nothing.

Any ideas? Can someone, please, help me? Does anyone tried to remove the emmc, flash it with a mcu or something and solder it back?

Samsung i780 Dead... Power cannot start...

Hi anyone...
Need help to see if there is solution to my dead i780. After charging for quite sometime, the led indicator still remain "RED". I suspected something went wrong so I unplug the power and the red indicate still there. I tried switching on or off the phone but was unsuccessful. No choice, I have to take out my battery and place it back. After doing so, the phone cannot be turn on anymore!!!
Having an external battery charger and spare battery, I tested with a different battery but still unsuccessful. Charge the existing battery with the external charger have no issue. So I concluded that the problem now lies with the phone... any solution? or anyone encountered this before.
If I send for repair, is it worth it? $20++ for checking and $XXX.XX for parts.
Thank you.

[Q] Samsung I9000 bricked while charging

Please help me!!! My I9000 was suddenly turned off while charging although I didn't touch it. I did remove and re-install the battery but still couldn't either restart or get into Download mode or CWM.
The battery was 22% left before charging. The temperature of the charger and I9000 was hot. But they're often hot while charging, sometimes it shows 40 oC.
I'm using Innovation 5.2 JVS ROM with Semaphore 1.7.5 Kernel.
Is my phone bricked? Please help me !!!
As i'm developing on my phone its almost constantly on the usb charger too.
I once had a similar issue, where it would not show any sign of life, no download mode, no CWM nothing, no keys lighting up either.
I had already printed out an Amazon RMA and packaged it, just randomly i thought ah wtf lets try it one more time.
So i put it pack together, put the battery in and it worked like nothing happened and still does...
I still have no clue what happened, though i have some suspicions about somekind of overcharging failsafe...
I would suggest leaving the phone without battery during the night and try it after that again.
Thanks a lot Dark3n. I'll try it right after back home.
There's no hope. I think the power ICs has been... died. I'll take the phone to Maintenance Center.
Anyway, thank you Dark3n again for giving me a way.

[Q] [Help! Phone stuck at 5%]

Hi, I have had my Motorola Atrix HD for 2 years now and just today my phone was stuck at 5%. I tried to see if it was my charger but it wasn't, then I looked at the battery and it looked normal as usual so I tried to just clean like the dust off the charger. I also tried to reset my phone to see if that helped but still no luck... I don't know what to do! Is my phone broke? The reason I want it fixed is because obviously the warranty is gone and I can't purchase a new phone. So I just want to see if anyone can help me... I forgot to mention that when I power off the phone it turns on ( plugged in to charger) shows a battery with a question mark in it. So please if anyond can help please do

[Battery - LG NEXUS 5] Always 0%!!!

Hello to all, as in the photo that I enclose, since replaced the display on my nexus 5, the indicator of the battery charge remains always at 0% ... if the detachment from the current, continues to run regularly for a few hours.
I also tried replacing the battery with an original but to no avail. If i turn off the phone there is no way to turn it back on if you disconnect the battery, attacking power, get it going in the bootloader, reattach the battery and then start ... crazy stuff. What do you think?
Sorry my english and thnks for helps!
Hello,
I am having the same problem after having replaced the battery... Did you find any solution? Thank you
Same problem here. I revived the phone after a water drop but now have exactly this problem. All good except for this. I replaced the battery but still the same.
The phone can use normally, just don't know how much battery left because always shows 0%.
And if turn off need to open it, disconect the battery, connect the charge, turn on and when google appear connect the battery back. Kinda weird but is how it works now.
Any way to solve this?
The same problem
It happened to me and I am looking for a new battery in Egypt
I have the same problem.
Even with a new OEM battery this happen.
Any news about a solution?
Exactly the same problem.. any solution?!

Xperia Z3 Battery problem

Hello, I have a problem with my Xperia Z3 (D6603), battery perecnt stays at 50% sometimes it jumps to 70%, 20%, 100%. One time it was dead for 3 weeks, when I plug it, it shows battery but doesnt charge. I barley managed to power it up, but same problen presists. Only way to charge it is by powering off the device and pluging in the microUSB cable in adapter that is connected to AC (220v) European. Is it the battery problem or some other hardware issue? Im so thankful by any reply, id be so thankful to solve this issue. Thank you guys so much. :victory:

I don't know, I bought it second hand. It was good for about 3 weeks and suddenly that problem startetd comming. I found a solution kind of. Remove the back cover and press hard on battery pin connector and it charges just fine. So is it the motherboard or the battery it self or the batteries flat cable? Thanks
Login into Sony account and type the imei number so you can check the warranty if there's any time left it'll tell you the age of the device as they have a 2 year warranty

Problem is fixed, if you have this problem and if you are lazy just press hard on back of the phone because flex cable is loose and right now I have 68% issue reoccurs sometimes but its not a big deal. If you know how to remove back cover just find battery connector and press hard on it while phone is charging until you see red/yellow/green led show you are good to go! I hope I helped someone, and thank you guys for replying.
If I helped you hit that thanks button
TRY THIS AT YOUR OWN RISK!!! I am not responsible for damaged connector/motherboard nor damaged phone. I'm just saying how I fixed my battery problem
