Hi, I have a 7 months old galaxy nexus (international) which has just turned into a paper weight. I was wondering if anyone here any help.
1) Charging problem:
The problem started when, all of a sudden, the phone restarted while being connected to a computer. I smelled burning and the microUSB connector was burning hot when unplugged. The phone still worked at the time but I couldnt charge the battery. After going through 3 different cables with the same problem, I then discovered online that this has been a common issue with the phone and the only fix seemed to be to replace the microUSB port.
I noticed that the battery might have gone dead also since I was not able to charge it. I went to a T-mobile store and tried on a new battery but the phone wouldn't start!
2) Replace USB:
I bought a new microUSB port connected to a mini circuit board (identical to what's in the phone) and replaced it myself. The only thing I might have missed was that this particular (Samsung galaxy nexus instead of verizon) version has the volume rocker connector soldered onto the motherboard and I had to sort of yank it out. Well, I thought, so I'll be without volume adjustments, so what? And since the connector was still in place, I might still have electrical connection after replacing the motherboard.
Tested another time at the T-mobile store, still nothing.
3) Dead phone:
I followed the online instructions and attempted all kinds of sequences involving charging without battery, waiting for 10 seconds, pressing volume buttons while powering on ... you name it. Still nothing.
Going through Samsung wasnt helpful since I dont have a receipt (the phone is 7 months ago based on its serial number) since I bought it second-hand.
Any idea will be greatly appreciated!!!

additional info
The samsung GNex seems to have some unique quirkiness. When I plugged it in now, the screen, for ~10-15 seconds, will show the battery being charged, before going blank again. And this shows up only sporadically. Another quirk is that if I remove the battery and connect that directly to a PC, the computer will make a sound, indicating the connection, then quickly makes another sound indicating disconnection, before making the sound of connection again and it just cycles continuously until I unplug it. During the entire time, the phone never appeared on the computer screen. If I have the battery in, then the PC wouldn't even make a sound.
I also tried adding some slow-curing conductive epoxy at the solder joints that I had to detach when replacing the microUSB circuit board and that didn't do a thing.

Changing the microUSB port isn't hard at all. There's a good guide over on ifixit.com
Also, the screen turning on for 10-15 seconds is normal for when the phone is off and charging.

Thanks for your reply. I too got information from ifixit.com and replaced the microUSB port successfully (with the exception on the tiny circuit board connected to the volume toggle, which was soldered onto the motherboard and I had to detach it). But the problem is that the phone remained dead afterwards. The only other reason I can think of is that my repeated attempts to charge it while the microUSB port was burnt might have burned something else on the motherboard maybe?
Thanks again!

OMAP flash didn't work?
Just tried using the famous OMAP flash method. I first plugged in the phone, without battery, to a computer. As discussed before, the PC would beep intermittently, indicating a device is connected, disconnected, then connected .... Device manager was flipping constantly as well, as if I am plugging the device in and out. I had to act really fast and double click on the device (during that split second when it's showing that the device is connected) named OMAP 4460. Once the separate window is open, I then click "change driver" and point to the downloaded file.
While I managed to get that part completed, I was unable to proceed from that point. Nothing else seems to have changed. What doesnt make sense is me still is how that should even matter since the problem started with a hardware failure, and why a software change would make any difference.
Any input will be greatly appreciated!
Hello XDA members. I have a very troublesome issue with my galaxy tab 3 7.0 inch tablet. It will NOT turn on at all, no battery charging, no device power on, no comp recognition, nothing. I have already tried:
Letting it charge overnight (factory charger along with others) with several known working cables
Unplug battery for 5 minutes
Press and hold power, Vol Down, and home for 10 sec, 30 sec, and 1 minute
Press and hold power and vol down for 10,30,60 seconds.
I sent it in for repair and they wouldnt fix it because it's rooted. When I got it back it briefly turned on to the battery charging, but nothing since. I'm thinking there must have been some way they got it on.... All proper drivers are installed on PC and it's never been dropped, water damaged, etc.
Would anyone be able to provide insight as to why and provide a fix?
My 8 inch tab 3 wasn't coming on either a few days back, I got it back on by holding home and the power button for a while. I was about to give upwhen the battery charging image came on. I think I did the same again and it came on normally.

Was that from computer or wall?
From wall, it was about 3/4 charged by then

Still no luck... I can feel the tablet getting hot down at the charge port so I know it's charging, and i know the lcd isn't damaged.
Mine is in the same condition. Anyone know how or why this happens and how to fix it?

Not sure if this will help, but just like with phones, sometimes android tablets just need a battery pull. My kids xo tablet went dead and before I tossed it in the trash I took the housing off and had to clip the + wire since it was soldered to the board. Twisted it back together to check and sure enough the tablet powered on like normal. Ive had to pull the battery on an Sm-t217a and it was a lot easier. They have a removable clip that attaches to the board.

I think it might be the battery itself. Just for giggles I left it plugged in for days and i just checked back on it and the Battery charging screen kept flashing on and off. Won't hold any charge. Probably will just order a new battery and see what happens. I pulled the battery a couple times and nothing happened. Closer inspection found that the tech that looked at it damaged the battery cord (unless it came with the copper on the wiring already exposed...)

You might be right about the battery being dead, although they usually don't just go all at once like that. The charge indicator flashing is odd. The only thing close I've seen is an "x" over the icon when there aren't enough amps (my tab needs 2 amps. 1 amp chargers and some pc usb ports give me the x.
If you have an old cable you can cut, you could try to charge the battery itself to see if it takes a charge (or at least use a multimeter on it to check for voltage). Then you could narrow it down a bit to whether it is the battery or possibly the charge port/hardware..... I saw a bit of exposed wire just before the clip of mine too, made me extra careful pulling the clip up.

I wouldn't even know where to start with the wiring. Multimeter isn't something I have access to, and it seems a little complicated for me to spend time on.
When I say it's flashing, I mean the device powers on to the battery charging screen, then dies, wash rinse repeat. If I go into recovery, same thing. It all happens within a couple seconds, so it's hard to describe.
My dad has one that I can pull the battery from, I might do that. Batteries are like 20 bucks on amazon, so I think I'll test with my Dads and if it works just order a battery and report back here.
similar problem here

My daughters tab 3 7 inch T210 also refuses to start. First time it was fixed by opening the device and disconnecting the battery. Now that doesn't help anymore. If I attach the original charger and measure the voltage when the device has rested for some months I can see that the voltage slowly rises so it seems to do the charging even if there is no sign of charging on the screen. After some hours of charging I measure 3,78V on the battery, after disconnecting the battery.
If I attach the battery and turn on the device I measure 3,76V before I push the start button and 3,74V directly after pushing the button. After about 15s the voltage goes back to 3,76V. Nothing happens on the screen... Tried with different combinations of pushing on-button and volume up, volume down, menu....
So -the best thing would of course be a quick visit to local shop to buy a new device of another brand but for some reason I refuse to give up.
Any advice would be appreciated.
(I Have made no significant modifications but the 4-year old daughter may have contributed in an unknown way )

The better way to test if your tablet can turn on: buy a new battery, under $15 on Ebay since your old battery is dead or completely drained.
Use the new battery to turn on your tablet. If it's on, check the build number of your device after go to About My Device: if it's not end with OB1, the latest firmware which fix charging issue.
It's more likely your build number is MK1 to NI1, the build numbers count by alphabet order. Upgrade the software via Wifi, battery must be at least 25%, otherwise your tablet won't allow you to upgrade. Bring the firmware to the current OB1, your tablet should take charge normally, otherwise the USB charging port is defective or damaged. This micro USB is cheap, around $2, but it need to solder to motherboard to replace the defective one.
So I'm trying to help a friend out who's on a pretty fixed income with his bricked Note 8 LTE that follows the same pattern as all the other millions of users have experienced - tablet was on charge, went dead when they returned to it a few hours later. Started with the obvious - swapped the charging port, swapped the battery, tested a plethora of cables and chargers and no luck at all. No lights, no attempt at bootloop or even attempts to boot - nothing.
Here's where my version of things differ though; I have a USB power meter that can read the current levels and draw of whatever as long as it's USB. When I initially hook it up between the tablet and the charger, it reads zero draw at all BUT if I press any of the hardware buttons on the side (so Volume Up, Down, and Power) suddenly there's a tiny bit of power draw from the charger to the tablet which would imply something is alive in there. I've even gone so far as to use a rubber band to hold the power button down and leave it on the charger for a solid 8 hours .
Still no signs of life.
Since I'm at my wits end with this device and have thrown everything I've got at it, I figured I'd reach out to the community for help having noticed this quirky power draw.
Any ideas, anyone?
PS: There was never even so much as sideloaded app on this tablet prior to bricking - completely stock.
Hi there,
I have received this Galaxy Tab 3 (SM-T311) and it does not turn on nor charge.
I have tried the various suggested button presses, I have tried unplugging the battery for a while. Now I am leaving it to charge but this was already tested by the previous owner with no success.
I would like to find out if charger circuit, battery or motherboard need replacement.
I have tested with a multimeter that battery leads show 3.7V - with charger plugged or not. With battery removed the leads show a value of 0.4V.
Can somebody help to figure out whether it is a battery problem, a charger circuit problem or a motherboard problem? I think it might be one of the first two since battery charge should not be so low.
Thanks
By the way, I have already been through this video: https://www.youtube.com/watch?v=m2VJ_VRIRSI
Which comes from this blog post: http://www.bigpicturebigsound.com/Samsung-Galaxy-Tab-3-Won-t-Charge-or-Turn-On---How-to-Fix.shtml
I am not using the original charger and cable but a 2A one, sorry but I do not believe that the original USB cable and PSU would be any different it's like with HDMI, it's a standard. The only thing that could change is the power intensity which is 2A as per original.

Sorry I can't help, except to say it sounds just like my problem. I'd been using mine mainly as a clock/alarm clock using a great alarm app. The battery was good enough to last about 15 or more hours with a clock display on, but then I left for a 2 week vacation, and decided to turn the tablet off rather than leave it on a charger. Came back and it was dead.
I also did all sorts of button presses, used various chargers and cables (I have the original charger, which works for other devices, but didn't help). I disconnected the battery for several hours. Tried charging off a computer USB-2 port. etc, etc. Still, "It's dead, Jim".
I suspect it's the battery, which is pretty old now, and has been left on the charger a lot lately, though not 24 hours a day. Lithium batteries don't like to go totally dead, but I guess that's what happened. If the tablet were still useful to me, I'd try a cheap one from Amazon, not really expecting it to last a long time, but useful to see if it works without losing too much.
I've seen one repair tech who fixed a similar problem by disconnecting the battery and connecting it to a power supply briefly to give the battery enough of a charge to get the phone to start charging it normally. Obviously, this is something that mere mortals would not be able to do.
Hi guys,
hope you can help me with the following.
I recently got an A5 2017 which wasn't used for 2 years.
Obviously the battery was dead, which was confirmed using a voltmeter.
I ordered a new one, tested it with the voltmeter and installed it in the phone.
When I plugged it to charge, after a few seconds I can see the charging animation showing up, it's at almost 85% now.
But I tried and cannot start the phone.
I tried many keys combinaison with no success, all I can have is the phone's charging animation.
I dismantled the whole phone and none of the liquid sensor seems triggered.
I removed both SIM trays and SD card as well, no luck.
Only while plugged in to a socket turns on the screen with charging percentage.
I tried to connect the phone to USB to my laptop and it doesn't do anything.
Any suggestion here?
Thanks

Whilst unplugged, press and hold the power button for literally a minute. Release. Wait 10 seconds. Press and hold power until turns on.
It may work.
It may not
Worth a try
Annnnnnnnnnnnnnnnnnnnnnnnnnnd it switched on, I don't know why nor how.
I put the back cover in place (the one above the battery, not the one of the phone itself) which in my opinion links the power button to the motherboard itself (but I may be wrong) and it switched on after just a few seconds pressing the power button alone.
Hope this helps someone else, anyway thanks a lot for your reply which is much appreciated.
