I hooked up my TP2 to the charger after school and my phone seemed to be fine.
The battery is kinda weak these days and I should probably buy a replacement, but I haven't had anything happen quite like this...
Late in the night, I checked my phone and noticed it was in an endless loop of - vibrate, then show stock pinkish and white welcome screen (Tmobile), turn off, repeat. I vaguely remember the screen turning on and off earlier in the day, but I didn't pay much attention until now.
So, I took the SDCard out thinking it was XDAndroid messing things up, but it continued to loop on and off.
Then, I took the battery out to see if I could get it to start with just the charger. It would not. I thought this was strange, since I took the battery out while it was plugged up a few days earlier and it stayed on.
I also tried the tiny little reset button in the hopes that it would stop the loop. But of course, that didn't help.
Eventually, I pulled out my old Tmobile Dash. The old Dash booted fine yet I haven't charged it in several months. Everything about this old phone is excellent, and to this day I think it's one of HTC's finest phones.
I looked at the batteries. Same power connectors, nearly the same output. 500mAh difference between the two, but they had the same voltage. So I stuck the Dash battery into the Touch Pro 2. Unfortunately, the Dash's battery has a tiny notch on it that prevents me from using it. Looks like I could tear that off easily... but I figured it was there for a reason and looked online for solutions.
I couldn't find anything online that seemed to help.
So... I tore the little notch off of the Dash battery. It was a lot easier than I thought it would be, since it's not actually part of the battery, but instead part of the plastic wrapping around the battery.
After that I was able to line up the connectors and hold the battery in place. I didn't have to touch anything and the phone came to life.
Oh great! I thought. Then I plugged the phone to the charger and took the battery out. The phone died. I was surprised that the phone couldn't stay on as I've seen before. I tried this a few times, switching the batteries out as fast as I could.
No matter how fast I switched them, the only result would be an endless boot loop and no charge.
At least now I knew it was the battery. I had assumed it was XDAndroid (I had just installed the October kernel - which by the way is much more stable and fasterthan what's used in the July FRX07 release package).
Since Android wasn't suspect anymore, I thought I'd try booting into it with the Dash battery. Once it was done booting into Android, and with the charger connected, I took the battery out.
It stayed on.
Now I was getting somewhere!
I put the original battery back into the Touch Pro 2, put it in Airplane mode (turning off all wireless devices), and now it's charging.
It was kinda funny to see the charging levels during this process. It was at 94% with the Dash battery, then I took out the battery and it stayed there. After putting in the TP2 battery it went down gradually to 54%, and it probably sank lower before rising again. It's now at 71% I'm thinking of maybe turning it off and leaving it connected to the charger to see if it'll start with the loop again. If it doesn't start a loop, then it'll charge faster since it'll be turned off.
Long story short:
When this happens to your Touch Pro 2, it's your battery. I don't recommend fooling with a Dash battery like I did, instead, buy a stand alone battery charger like this one: http://www.amazon.com/Travel-Charge..._1_4?s=wireless&ie=UTF8&qid=1318308064&sr=1-4
Or maybe buy a brand new battery. Don't buy cell phone batteries from Amazon though, try getting it from HTC if you can.
My experience sucked, and I hope this post will be of some use to other people still using this particular phone.

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.
I've done lots of searching, but I haven't found anyone with this specific problem.
(Too long; didn't read it) at the bottom.
So it all started about a month ago. I plugged in my Evo 4g for the night (As the battery often lasts me a full day.) at around 10% I sleep very well and peacefully. When I wake up in the morning I notice my battery is still at 10%. "CRAP!" I thought, "Did I forget to plug it in?" So I checked everything, made sure it was plugged in, and went to class, without the phone of course. When I got back later that day, I went to my phone, and it was STILL at 10% I was freaking out. I thought my battery had died already! (At this point the phone was less than 2 weeks old.) Finally after being unable to charge, and only having 10% battery, the thing went kaput. Died. I could not for the life of me charge the phone. So I left it sitting around while I had screaming matches with not only Sprint, but the Radioshack I picked it up at. Ugh. About a week later and just as I was about to pay $100 for a new phone, I fixed it. I don't know how, or what happened. I plugged it in out of habbit, and BAM it started working. "**** YOU SPRINT!" *Hangs up phone.* I went on my marry way, being extra careful now to monitor the battery (Which was charging very normally, and lasting me a full day at little to moderate use) Then one day I was just sitting around playing videogames this past Saturday and thought "I'm not using my phone, I'll plug it in and forget about it." (The battery being at 70%.) I plugged it in and about 4 hours (And some amazing killstreaks on CoD) later, my friend called me to ask if I wanted to get lunch (He called my Evo, of course.) "Sure! I'll be right there." I hung up, closed the phone app, looked at my battery, and my heart sank. ...70% "NOOOOOOOOOOOOO!" (Read: Darth Vader) How could this happen AGAIN?! I used it for the rest of the day conserving as much juice as possible, and trying to charge it every chance I got. But alas.. it died once again. Now, nothing I've tried has worked. I pulled the battery over and over, plugged it in for hours and then tried to turn it on, tried a USB charger, and wall charger (Both HTC, the out of the box original) I tried my roomates LG chargers (USB and wall) Nothing worked! Then I was randomly pressing buttons when I held Power+Up (Which apparently is some kind of hacker-magic) and I got to a white screen! I thought I was saved! I let go of the power button to move around on the screen, or do something at all. Then nothing. It immediately went back to black. And now, it doesn't even go to the white screen anymore! So my question is, (Finally, god he rambled on forever) is there anything I can do to save my amazing phone outside of buying a new battery? Is this a known issue? Even with a new battery, would the same problem occur? And most importantly: What's causing this? Am I at error? Or is it the phone's fault?
Also, sorry for the long story, but I'm sure you get 1000 "Y MY FONE NO WERK?" And I wanted to make mine interesting, at least.
TL;DR My phone doesn't charge, tried every suggestion I could find.

This may sound really simple but......have you tried another battery?
Hello people
A couple of hours ago, my phone shut down due to empty battery. I came home, plugged it in and booted it, all was fine. At about 60% I shut it off and went to have lunch, when I came back and tried to turn it on, I couldn't.
Led was orange at the time, I unplugged the power cord but the led stayed on! I removed the battery to be able to reboot it, but when I re-inserted it I still wouldn't boot.
Now no matter how I try to charge it, led stays off like it's not charging. Tried various different cables/chargers, the same. Tried to plug it to the charger without battery but no led flashed. Tried to boot without sim/sd card, still the same.
Any ideas?
My battery has never been changed (for a year now) and has had a bunch of full drains. Could this be a dead battery? :/
Well seems the phone is fried... I tried two more official batteries and no go...
Sorry to hear it. I thought that at first when I read your thread but I thought because I am not the most experienced person here, there might be some kind of fix.
HTC will most likely if not certainly replace this handset for you, seeing as it just happened out of the blue.
Well I certainly hope so, problem is I suspect it's an import (from another European country) and local HTC service generally does not do well with European imports.
Anyway I'll give it a try, meanwhile I'm getting a sensation soon
I have a similar problem.
I'm lucky that my girlfriend has the same handset as I do, the I could compare the phone abnormal behavior tho that of her properly working phone.
The first thing I've noticed, after a while when the charger was attached, was that the phone is very hot and that the battery keeps draining out in a surprisingly high rate.
After a while I've noticed that even when the phone is turned off it wont recharge. Sometimes the Orange LED is on when recharging while it is off, and the LED stays on for a few seconds after removing the charger, as if it was still charging. Note that the affects of connecting the charger to the phone, are mainly the ones listed below (not necessarily altogether)
* The phone indicates as if it recharges.
* Going to an infinite loop of rebooting and crashing.
* Getting hot when power supply is plugged, or at any time when the phone is turned on.
Ultimately the battery was empty, and the only way I had to keep using the phone (mostly to diagnose the symptoms listed here) was to swap the battery with the one of my girlfriend's device, and charge my battery in her device while using her's. That's the place to mention that the battery works just fine and that the phone is draining any battery, no matter what.
I took it apart to have a closer look at the source of all of the heat emitted while the phone is turned on, and it seem to come from the motherboard itself.
That's all I have.
The worst thing is that a friend of mine who helped me opening it up broke the pcb of the volume keys. Now I checked and It turns out that that pcb is actually part of the flex cable, which sort of extension of the motherboard and is mainly the second most important piece of hardware of all the phone parts (not that there are so many). If I would be able to expose the conductors inside the flat cable I might be able to solder an alternative volume pad I'll make out of old some miniature switches I have. The cable is very thin. any Ideas of how to expose the relevant conductors without ripping the cable apart?
Just a (late) update:
It's been almost two years, I had given the phone to a close friend of mine after a couple of weeks since writing the first post, just in case he could resurrect it, nothing.
Then, a couple of months down the road, the phone suddenly woke up! He tried to connect it with the charger, after months of not being able to charge or boot it up and somehow it worked. And it has been working flawlessly ever since.
I just got it back to give to my girlfriend until her sensation is fixed, flashing Viper now
In case something like this happens to any of you, don't give up!
After a long day streaming Pandora from my Tab S in my car, running on battery, no charger connected, I decided to put it on a charger and turned on navigation about an hour from my destination as I was in an unfamiliar city. After about 45 minutes, I saw a bright green flash from the screen. A few seconds later, and there were more flashes and it turned off. I have not been able to get it to come back on. I have tried charging it, on a charger and on PC. I have tried every combination of home+vol up/down+power I have seen in several threads, while connected to a PC, to a charger, and not connected at all. The PC does not recognize the Tab at all, ever, during any of the manipulations.
I have seen where some have luck just letting the tab sit for a few days, and it will be miraculously revived by charging, so I will try that. I have also seen where some force charge the battery using the wires from a stripped USB cable directly on the battery terminals, and as my warranty is long past void, I will try that too.
Here's my question: If none of that works, given the description, does anyone have a good idea that it may be just the screen or the battery that may need to be replaced? Or is it more likely a motherboard issue? Is there any way of telling? Despite the heavy use, the TAB did not seem excessively hot. I have felt it much hotter in the past .
I'm a tab-a-holic, and use this thing all day, every day. I use it for work, and for reading and movies at home. I'm a little frustrated as I have yet to own any tablet that lasted two years. I really don't want to spend the money for another one right now, and, if needed would prefer to repair this one if I can save a few bucks.
And, if it's relevant, the Tab is rooted, running AOSP 6.0.
I don't know too much about this - but if I were in this situation, I'd put it in a refrigerator for about 1 minute and try booting it up.
As for the cause - AOSP 6.0 has been known to have some overheating issues on this tablet under heavier loads.
Yeah, still don't think overheating was the cause. Not gonna put it in a fridge either. ;-P
Thanks to all for your concern and helpful comments!
My Tab S is unbricked as of just a few minutes ago! I just let it sit for a few days, and then left it on a charger for a few hours today. I was not expecting anything as the battery icon did not pop up when I plugged it in. But, when I came back to it a few hours later, I pressed the power button and there was the battery icon showing a full charge. It booted up normally with no issues and is working fine.
I can't tell you how happy I am!
I've been having all kinds of trouble getting my tablet to charge. It's acting really weird. Over the last couple of days, I will turn the tablet on and it will say 80% charged (after being plugged in all night). Then, with it still plugged in, it will drain down to 15% in about 30 minutes. Why would it drain so fast (if at all?) when it's plugged in? It's also been taking hours for it to charge once it hits that 15% and I don't use it.
At first, I discovered my charging cable was to blame. I'd plug it in, but the tablet wouldn't detect it was connected unless I pulled on the wires just right for them to make contact. Apparently there was a broken wire inside the plug of the cable. So I replaced it with a new cable. Everything seemed to be working good then, and was actually getting proper charges again. Now though, it doesn't seem to want to work.
I was using the tablet yesterday to check my email. It had been plugged in all day and not being used. It said it was at 100%. After about 10 minutes though, the tablet shut off saying "battery low". When I try to turn it back on, I get the battery indicator showing it's at 0%. So I left it plugged in the rest of the day and over night. I just went to turn it on about an hour ago, and it's still sitting at 0%!
I thought maybe the cable was bad again, so I found another charger and tried that. It does the same thing the other cable does.. It stays off until I plug in the cable. Then, as soon as it's in, the tablet "wakes up" and displays the battery indicator. Like, it detects a power source has been plugged in. But no matter what I do, and how long I keep it plugged in, it stays at 0%. I can force the tablet to turn on by holding the power button. It goes through the boot animation prior to loading the screen. Then, in about 5 seconds, it turns itself off again.
I don't think the battery is truly at 0%. If it were, how would it be able to boot up without even a cable plugged in? I really don't know what to do now. I've rooted it, so I can't send it in to Samsung for repair. I don't even think the warranty would still be good at this point anyway. The tablet is at least 3 years old (based on when I joined this site looking for root help). And I think it was 2-3 years older than that before I bought it. Is there anything I can do?
I can't wait anymore. So frustrating to own something that's worked great then all of a sudden decide to no want to even power on anymore. I've spent all day trying to get it to charge with other cables. I've tried chargers, I've tried just straight cables. Plugging into the wall, plugging into the computer, plugging into the USB port in the car. Nothing works. So I hopped over to Amazon to just order a new tablet. I can afford it, not big deal there. But then I saw a ribbon cable used to replace the USB port on the tablet. Maybe the port is bad? Lots of "highly recommended" reviews. I went ahead and ordered one. It was less than $7. If it doesn't work, I still have the money to go forward with buying a new tablet. If it does, money saved! I went ahead and bought the "customers also buy" kit, with a replacement battery (just in case it's not the port), and a set of tools. If the cable is all I need, I'll have a spare battery. If the battery is all I need, I'll have a spare ribbon. If it still doesn't work, I'll go back to my original plan.
Just kinda bummed this is where I have to go now. Why would it suddenly just stop altogether like that? Is it because I keep it plugged in 95% of the time? Should I keep it unplugged till it's drained then charge it and unplug it again right away? I used to have to do that with an old cell phone. This is my first tablet so I dunno. If I end up needing to replace the whole thing, it'd be nice to know from experienced users what the best way to do it is, and what, if anything, I can do to prevent it happening again.
I'd suspect the battery is kaput.
It's not a good idea to keep the battery on permanent charge, there's no need. Let it cycle normally.
Well, all told this was an educating experience. I got the battery first. It came about 40% charged. Once it was installed I used TWRP to create a system backup and downloaded it to my computer. Then I left it plugged in overnight. The next day it was down to 30%. So the "charging" indicator on the screen was just a bunch of lies. I got the replacement charging port a day later and installed it. I didn't do anything else with the tablet, just left it turned off and the charging cable plugged in. It said it was charging, but again, after about 12 hours of charging overnight, the following morning it was down to 18%. So I'm returning both the battery and the port. They may still be working fine, and the problem is elsewhere in the tablet. I accidentally broke the little metal connectors over the power button (it's a contact sensor, and the connectors sit on top and complete the circuit when the button is pressed) when I took the back off to replace the parts. I also cracked my screen, although I think it's just the protector I put on it. I'm not sure what else to try at this point. The tablet is essentially a paperweight now. I can turn it on and watch the battery slowly drain to 0%, but I'll never get any more use out of it. So I decided to do a system wipe prior to putting it away for some future project to try and rescue it. Now it's stuck with the "Teamwin" screen flashing at me. I give up. I looked at Amazon to see if I could just buy another one, but they don't have any "new" left. They're all refurbished or "slightly used" from 3rd parties. I looked at other tablets, and bought a new Samsung Galaxy Tab S5E. It looks like it has the best reviews and marks. The only issue would be the wifi, but it seems to be a hit or miss with people. Some people say it's a problem, others say they don't even have a problem. So.. <shrug> I'll see how it works for me.
