I've got a TMOUS TP2 which appears to be stuck in a reboot loop of sorts cause I can't charge the battery.
I've read through the forums and I saw a few similar problems like this but it seems like it those they were stuck at the bootloader, and that's not the case for me.
Basically the battery was down to 14% and I turned off the phone last night intending to charge it this morning. Somehow the battery dropped to 1% by the time I went to turn it on this morning, and it shutdown (really just lost power) right after I started it. So I go to plug it into the wall charger and then:
charge light comes on
after a few seconds charge light goes off
the phone tries to boot (does little vibrate, shows splash)
after the splash screen, phone loses power
charge light comes back on
then tries to boot after a few seconds.
repeat
If left unplugged the phone just sits there dead, but upon plugging it in, it tries to boot.
I've seen it where the phone doesn't have enough power to boot and just needs to be charged for a while, but I can't seem to do that here.
Anyone have any idea how to prevent it from trying to boot after the AC adapter is plugged in?
Thanks

If you're desperate...you might try doing a hard-reset.
Why would that help? I don't know...except sometimes when really stuck it helps to just change the situation...try something completely different.
Of course, a hard-reset deletes all data and applications that you've put on the phone, which is why I suggested it as a recourse if desperate.
Probably keep the phone plugged in while doing hard-reset.
Same problem, solved by itself
Hi,
I had a similar problem with a standard TP2, it was clear a battery fault. Phone was working well with a new battery and, of course, another working phone couldn't boot up with the faulty battery.
I took out the defective battery and let it aside for almost 2 weeks. After that it started to work, but the capacity is clearly smaller.
So from my experience, a hard reset wouldn't help you.

Yes, it goes without saying -- though it's good you did -- that if you have access to another battery that's an obvious thing to try first.
The hard reset is worth trying, in general, for otherwise-unresolvable phone issues.
It's a dead battery. Same exact thing you describe happened to me. Granted, it was because of water damage but same symptoms. Thinking the phone was dead I went and bought a new one. Then I decided to try the new battery, bam, phone back alive. Returned the phone and bought a new battery. By the way, the dash2 battery fits as well. Tmobile stores didn't know it... But the connectors were the same do I tried in the store and it worked.

So it was indeed a dead battery. Oddly I found someone who had a CMDA TP2 from Verizon (mine is GSM TMO), and was able to pop my battery into their phone for a minute or two and charge it to about 5%, then put it back in my phone and all was well. With their phone, plugging in the charger did not cause the phone to start up and then power cycle.
That's really weird "glitch" if you want to call it that. So mental note, don't let the battery run down too far.
Model: Tab S T805M (that's the 10" with LTE) rooted and stock firmware. I've had it for over 6 months and nev er had any issues, ever!
Yesterday I fully charged the battery using an original Samsung charger (from my late Nexus 10) until it was full.
I then used it for a while (basic stuff) then installed a game (Hill Climb Racing), played for a bit, then let it sit on the coffee table. Naturally, it went into sleep mode. Once I tried to turn it back on, about 30 minutes later, it was dead.
It doesn't have a SIM nor micro SD card in it.
I tried the key combos to get into bootloader or recovery, no go.
I tried holding power button for several seconds, no go.
I tried connecting the original charger that came with it, no go.
I hooked it up to my laptop, the same I had used to root the thing months ago and has Odin and all drivers installed and everything, no go. It won't even acknowledge there's some USB device connected.
Then, for some reason, while still connected to the laptop, I was randomly pressing buttons on the tablet (out of mild desperation, I was tired, just wanted to get it fixed and get some sleep) and I saw the battery logo again. It was at 99%, the way it was wen I last used it. So I unplugged the tablet and booted it normally.
Then, again, I used it for a while, connected to my WiFi, everything normal, and once it went into sleep mode, it died again. No buttons, no USB, no response to charger.
So, the problem is repeatable, but I haven't figure out yet the exact procedure to bring it back from the dead.
I'd like to fix it, even if I need to flash the stock ROM back on and lose root. If that's impossible, I'll settle with a tip on how to reboot the stupid thing once it enters this state. Then, eBay, here we go.
KNOX was tripped when I rooted, so I guess I can only try my luck with the warranty.
I think you should start your post letting people know that you have rooted and flashed your 10.5" and not in the last three lines.
Do you think your battery level is being reported correctly, as if your tab thinks you have 90% left when you only have 50% , then you game and use 50%, and think you still have 40% left but when your battery hits 39% it will just die, no battery warning or anything.
Flashing a tablet can cause the battery to be reported incorrectly, since you are rooted, download a free battery calibration app off the play store.
You say you have had your tablet 6 months, if you game or use other apps that rapidly drain the battery, the battery might be failing.
Since you say the fault is repeatable i would have the tablet replaced, flash it back to the stock rom and remove the root, Can you reset the KNOX counter, I think i read you can somewhere on this forum.
Good Luck

Yes, I did mention in the FIRST line I had a rooted device with stock ROM.
Tonight I was just able to enter bootloader and stock recovery and did a data wipe / factory reset. Let's see what happens now.
I'll install a battery tool to see what's really going on. Maybe my battery is ****.
GSam is the battery monitor i use, have a look at the alarms in the setting, I have them all set, I got a high temp alarm while my tab was in it`s case while i was asleep in bed, I remove my tab and the back was hot, just shows what can happen when you think your tablet is sleeping.
I bought my 10.5" before Christmas and it has never been turned off or rebooted, I have about 170 days continuous use in the battery settings, so it`s been quite reliable for me apart from that little temp hiccup.

Strange symptoms started a week or so ago. Phone works normally while plugged in to charger, and seems to get up to 100% as normal. When taken off of charge, it will slowly drain as normal...
But then, for example, it will be on 95%, and then just turn off (or maybe say the "Shutting down battery low" screen, then shut down). When I turn it back on, it might say 92% (dropping a couple percent points.
OR, when I turn it back on, it might say 3%, and be almost dead.
And then after a while obviously it will shut down again, as the battery is almost dead. It just did this from what it said was 3%, but when I restarted the phone... it now says 85%!!
So yeh, it seems like it can't decide if the battery is full or drained or both. I have tried full restarts, and this is a factory reset phone at the moment too so totally empty and on stock ROM. Not currently rooted either, as I restored everything to stock recently.
I'm assuming the battery has broken itself, somehow. It seemed to happen very suddenly though, as it was working a couple weeks ago. But before I sell it for spares/repairs, I thought I'd ask in case there was another possible cause!
edit: Also, once or twice when the phone has restarted, it has gone to the "Android is Starting Optimising application 1 out of 144" screen, where it configures all the apps? I thought it only did this on a factory reset, or after installing a new rom or something. Weird.
Yes, sounds like a dead battery:

Quite a few of us have had something similar and replacing the battery fixed it for me.
Hello. Im sure there is plenty of such topics in the forum, but I believe, that my case is specific and I hope we could resurrect my phone somehow together.
So last night I just send a WhatsApp VoiceMessage to my friend as suddenly my phone started shutting down, just like if it had 0-2% battery power... But it actually had over 40% battery life... I thought ok, yeah, might be battery, so I plugged in the original charger and the phone didn't show any signs of being alive. Then I've unplugged charger, toke battery out, plugged charger back in and I saw that its still alive, telling me "please put the battery in, there is nothing inside me to be charged". So I placed battery back to the phone and guess what.... It shows no signs of being alive again, the battery wouldnt charge... Then out of panic I started to do random stuff like holding power button for 10secs for soft restart, holding power button and volume down button for what ever that was... Plugging charger in and out like crazy... The phone was just dead! So I had to give up... I toke the battery out and let the phone lay for like I dont know 2-3 hours. Later on, I came back, put battery inside and tried power button + volume down again.... woohoo!! , it worked, my phone started to boot! I thought this is it! Hes alive again, but ahahaha.... 6-7 secons during the boot, it just turned off immediatly. I thought yeah, must be battery, so I order new, original LG G3 battery... And while the order was on his way to me, I managed to charge the old battery after letting the phone lay for 2-3 hours and then plugging charger in again. It started to charge... I let it go up to 66% I believe and tried to turn on the phone again.... Guess now what? LG intro screen poped-up and the in left corner I just saw something with "boot error blah blah geeky stuff" and suddenly red and blue LED started to blink, red/blue/red/blue/etc... and the screen just turned off.... I couldnt do anything.... So I removed battery again and waited for my order... Next day I got no success turning my phone on with new battery.... I was playing around with different button combinations and remove/put battery and conclusion is.... The phone is dead except if you let lay without battery for few minutes... Then you can start charging battery for example... After that you can try to boot it, but it will just shut down immediatly after few seconds. Or you can try to boot it, but again, it will shut down immediatly and then you cant do anything until you let it lay without battery. I also managed to access recovery mode but I didnt start it, because I would like to get at least my data back somehow.... The phone is not that important as the data on it. I also tried to access download mode, for recovering my data, but without success....
LG G3 D855 Europe version
Lollipop 5.0 OTA version
Not rooted, Not modified
Any help would be really appreciated. If its impossible to resurrect the phone, can I save at least my data somehow? What would I try, please?
[Edit]
I just tried to start factory reset for sake of god.... Found some data recovery software on the internet, that might help after factory reset, but phone just shut down immediatly after I confirmed that I want to reset and nooow.... I see the LG logo like it would try to boot for already 20minutes and nothing happens

Thats what it appears normally when this happens a new battery is most of the time the fix....
Only other recommendations are try different usb cables and charging blocks....
As well as if you did not purchase a legitimate G3 battery I would try to purchase a new oem battery....There are cheaper aftermarket ones But I am one the the stick to oem type To many quality control issues imo...
I know Lg dont have the best track record for quality control either.....
Recently I posted about a problem others had as well - when under 50% ish battery, my HTC 10 would randomly reboot, and that would loop until it was plugged in.
Once plugged in and fully rebooted, the battery % reading would vary from where it was before to 1%. Also, certain apps' data or cache would be deleted. I would open, Macrodroid, for example, and it acts like it's the first time being opened after installation.
This has been exhausting, having to constantly be charging, staying above 60% - and even then it still happening. After it does, the apps whose data was cleared varied, and I wouldn't always know until I opened each.
So after this I dropped it and cracked the screen. I have fixed all of my HTCs before with various problems - M8, M7, DNA, Incredible, Max - so I decided to put in a new battery to hopefully fix the bootloop problem.
After watching a few disassembly videos, it seemed best to replace the screen when I opened it for the battery. So I ordered a screen, and waited more, constantly charging, restoring data to apps like Macrodroid and initializing apps all over again.
I finally have the new battery and screen. I have a few hours. I get out all my tools.
A few hours later, I have put it back together. It's like Medusa inside this thing! I was really being risky doing this last night, because I have a ton of work to do today, yet here I am typing this on my backup nexus 5x - so slow!
So the result? Success for the screen replacement, and the battery as well. But, now, it is bootlooping still! I plug it in, and two things:
Plugging it in does not stop the bootloop.
The charging LED does not light up.
So I am hoping someone may have some insight as to what I may not have connected properly. I can post pictures later, I'm not home right now.
I looked and looked and looked and cannot find where I went wrong. I am going to take it apart and put it back together if I can't find the error. Any ideas? Any other places I should post this?
I guess when I get home, assuming it has completely drained itself, I can plug it in, and see if it gets a charge, and if the LED illuminates. I am thinking: charging port is not properly connected back + the new battery did not fix the bootloop / battery issue.
Thoughts?
Bootloops/shutdowns are going to corrupt your data. I would RUU the thing before looking for hardware trouble, which you've likely sorted out by replacing the battery (of course, we're assuming the new battery is good).
BUT before that, is there a memory test in the bootloader or recovery? If so, I would run that very first thing.

Whatever happened to your phone? I have the exact same problem. Infinite boot loop, no illuminated LED, and no way of getting into recovery or anything else with it bootlooping. It occurred after I made the mistake of trying to restart it at 25%. I have the new battery and screen. i'm going to attempt to open this Pandora's box. Seriously going to have to turn my back on HTC. The 10 is so full of software issue problems regarding the batteries that they never bothered to address.
I did the exact same thing a few days ago and my phone won't charge or boot, but I do think the problem is with the button strip, that's what i think, because i tried turning it on before re assembling it and it did turn on successfully and was charging normally but when i re Assemble it, the phone got this problem, now i think when i turned it on before assembling i pressed the power button with a screw driver because i couldn't press it with my fingers, I think there i messed it up, any advice how to fix the button strip and remove a slip nut would be very much appreciated
I had the exact same issue as you(shutting down at 50%), have you found any solution to it?
edit: I THINK clean flashing oreo firmware then latest RUU then twrp then lineage fixed my issue, charging to full rn will drain it over the next day and report back if its gone for good
