Hi eveybody,
Today, a problem I have been experiencing for months (years ?) became critical : I cannot charge my Nexus 10 (lollipop) anylonger. To make it as simple as possible, here are the symptoms :
1) When my tablet is ON, if I plug the micro-charger (or any other one, same), nothing happens, no charge ( and no PC recognize if connected to PC).
2) When the tablet is OFF, if I plug the charger, the tablet viber briefly (this is normal) - which means the tablet realize I plugged the charger - but the screen stay black, and after about 10 seconds, I can see a (very very) brief flash on the screen, then the tablet viber again (same like the first one !), and it restarts over an over again in a infinite loop. I never see anything on the screen, just infinite loop viber every 10 secondes. If I unplug the charger, then the next reboot the tablet will boot normally... Of course, when plugged and looping, the only way I have to power it off is a hardreboot (or unplug, wait it boots, and the poweroff.)
I have NO IDEA on what to do... In one hand it seems an hardware problem, on the other hand (due to the past experience, when it worked in a wierd way, see below) it doesn't. At this time, I still have 60% of battery, so things can be done (dunno, change to factory version of android ? but without PC...) ; when it will reach 0%, this is the end I guess. :crying:
Any help is welcome... thanks !
Here are the previous "version" of this problem, I had been experiencing for more than one year : exactly the same thing happened but only when the tablet was hot (after I used it). When it happened, I just waited for a whole night, and on the morning, I plugged, and it charged normally. Don't ask me why, this is completely mysterious for me, but that what happened : hot, didn't work, cold, worked...

This was what happened - my N2T went dead, and I charged it up to 100%. It has previously been rooted with TouchNooter, and since my market wouldn't open, I overrooted it with TouchSalsa. Or so I remember. It may be different. I just remember that I used 2 different roots over each other. Didn't think anything would happen...
Anyways, all was fine and dainty with the N2T till the day the battery's charge was depleted. Charged it to full - Battery Indicator went green - and then proceeded to unlock it.
It was still responding at the lock screen, but once I unlocked it, it went straight to my Android home screen, and it just hanged. It has been showing the Android homescreen for quite a while now (probably due to the static e-ink screen, I believe it has died for a long long time), and nothing I do will make it reboot. I thought about forcing the battery out, but it was not user removable.
n2T-recovery wouldn't work too, as I can't make it reboot.
Any answers as to how I could make it rebott and/or restore the firmware like how I could force an iDevice into DFU mode?
Any help would be appreciated, as I imported this device into my country and it is not possible for me to send it back .
If anyone has encountered this problem before, feel free to shout out here too. My Nook Simple Touch has died for around 2 weeks now. I was hoping that the battery would run out and I could charge it but.... the battery indicator STILL shows green when I plug it in.
Also, whenever I plug it into my computer, the connected sound that happens when you plug in a USB drive just sounds - followed immediately by the disconnect sound. This happens in a loop until I plug out the Nook.
Try disconnecting the battery (by opening the nook) ...

Same issue, i already open the cover and remove battery, the screen still display screensaver. Then I plugged NT into wall charger , then removed (to try make it reboot). Plugged battery into again but , plugged charger . But nothing happened, still the same.
Any other solution?
Just a hint: It appears that the Nook won't boot without the battery in.
I don't know if it's an interlock with the temperature sensor on the battery.
The chip that does the power management is capable of powering a CPU with a dead/shorted/missing battery.
Guess no one had a similar issue?
It is the same with my NST. It was bricked when I root it back to factory restore. The battery light is green, do everything you did to the battery, still no respond. I am not in the US so I can not take my NST to the local B&N store.
I get my NST only 1 week...
PS:Finally I get my NST back following this thread

So, I have a Samsung SM-T230NU. When I tried to power it on, it flashed for a split second the Samsung Galaxy Tab 4 logo and then went blank. I figured it was out of juice, so I plugged it in and let it charge for an hour or so.
When I came back, it was flashing and going dark.
I tried a different cable. As soon as power was applied, it flashed and went dark again.
Now, the boot logo is showing for an even briefer amount of time.
I am suspecting the battery or USB port. I don't have parts readily available to swap, however.
It may be worth adding, when I plug in the device, without touching any buttons, the screen starts flashing the Samsung Galaxy Tab 4 boot logo. I would guess a stuck power button, but the power button travels freely. When I unplug the tablet from the computer, the flashing stops.
Trying to boot it with power + volume up garners no response from the device.
Any ideas?
Having same issue here
Tried hard reset, no dice.
Tried opening the back to see if I can identify some loose connection, didn't see anything funny. I am not an electrician.
My sister's having the same issue with her T230NU. It still boots (it'll boot to the Samsung splash, but then it flashes off the screen in half a second; this repeats every 7 seconds), but only if it's plugged directly to the wall charger. She let it sit overnight to charge, and it's still got this issue. I'm pretty sure her battery was drained when the issue started occurring last night, but it doesn't look like the battery has charged much (if at all) since then.
Hi,
I have a problem with my Find 5: I am stuck in a bootloop. The Oppo logo appears and after only a few seconds disappears, the phone vibrates and then the logo appears again. And this goes on and on.
I can get into recovery and fastboot but the real problem ist that my Find 5 will turn of again after maybe one minute into recovery. I tried it with CWM and TWRP. When I want to turn on the phone or get into recovery without being charged, nothing happens.
Before that I haven’t used the Find 5 because the USB-Port was broken and it would not charge. Even if the phone had a connection, its battery percentage would not increase at all. Then I ordered a new battery and a new USB-Port. I installed the new parts and suddenly the phone started to work again. I flashed a new nightly of CM 12 and installed some apps. The next day (it was charging over night) I unplugged the phone at 30%.
When I looked at the battery chart, I could see that the battery percentage did not decrease and also not increase while plugged into the charger. Then after some normal use, the battery percentage jumped from 14% directly to 0% and the phone turned off a few seconds later. When I charged it, it was stuck in a bootloop again. First it took about 30 seconds between the reboots and after the Oppo logo disappeared I could see that it i charging but after some minutes the reboots got faster (every 8 or 9 seconds).
So I am having the same problems with the new parts again but I don’t know why because it worked for some time…
It seems that the battery is broken again but how can it be? It was a brand new battery and it worked for one nearly full charge. Are there some common mistakes when replacing the battery that I could have made to cause my problem? I don’t know what to do and I want to try everything that is possible before getting a new phone.
Edit: Now I know where the problem is (or where it is not) but I have no idea what to do against it. The problem lies somewhere in the mainboard. Because when the charger is plugged in the phone will start to reboot again and again so the cable between USB-port and mainboard should be ok. But the battery is not charging. The phone worked with the new battery for a while because it was already charged when I built it in. And now since the battery is empty again I am experiencing the same problem as before again.
So does anyone have an idea? Where is the exact problem and can I fix it without spending much money on it?
Thanks for your help

I have a stock G4, which I replaced the screen on a few months ago.
Every few days, it randomly powers off and then wont turn back on. When I connect a charger, I get a bootloop with the splash screen appearing/reboot cycling.
Fastboot works (although I only tried this with a charger, not a PC attached).
Eventually the phone will seem to reboot correctly (after charging for a while, rebooting into fastboot)
One thing that does seem to work is 5 minutes in the freezer... After a restart this shows that the last crash occurred with 92% battery. - but then it keeps powering off with no warning, and fastboot indicates low battery...
I'm guessing either hardware/power management issues, or battery problems - the phone is 2-3 years old...
Edit : Further messing about suggests the battery is completely hosed...
Hello,
My yotaphone had some big issues after I've changed earpiece, the actual situation is:
- With plugged battery phone is completely dead, nothing happen pressing the keys and the pc recognize it as an usb input device (no adb/fastboot support)
- If I disconnect the battery connector and then plug in the charger, phone starts a bootloop "powered by android", BUT if I plug in battery DURING bootloop the phone boots correctly to the system but battery is 0% (I bought a new battery and I'm sure that there's some charge stored) and if I disconnect charger it says battery low and tuns off
- I've noticed that if I put phone in download mode>connect battery and then disconnect charger, phone stays on and it happens also during "optimizing apps" step during the first boot after update.
Now, I'm not sure of that but I think that it's an hardware issue (like the "daemon" that reads battery amperage doesn't work anymore) but I need your help tho confirm this supposition and even some things to try before throwing away my beloved yotaphone 2
p.s. sorry for my english
My YP2 has had problems with QI-Charging and random reboots since two weeks, maybe from falling down..
Two days ago, the YP2 got very hot, the battery has blowed and the YP2 was in bootloop.
After changing the battery, the YP2 will run like new again.
problem identified!
Finally I've discovered what's wrong:
battery connector is partially broken and the central contact doesn't touch battery terminal.
anyone have an idea if I can find this connector or if I have no chances to find it?
