Touch pro 2 not booting!!!!

Hi, recently my touch pro 2 doesn't want to boot. It happened when I was using my phone on the net and the phone just ran out of battery.
Then it turned off. Afterwards I hooked it up on the PC usb charger. So i was awaiting for the phone to charge but then it just decides to 'turn on' unexpectedly - it will show the boot screen and then the windows mobile - then it just blanks and turns off.
I HAVEN'T done any of the following: hard reset or go to booting.
Is there anyway you guys can help me on what step I should do! please! thanks
* P.S
I Have no NOT rommed my phone at all. Just the normal touch pro that came with the phone.

have you tried charging your batterie the normal way instead of true usb? Maybe that wil help.
If that doesn't work and if you are sure that the batterie has sufficiend power try to hard reset.

I have this exact same problem...I'll lay out how I've tried (and failed) to fix it for anyone who knows what they're doing to look at.
I have tried both hard resetting and soft resetting, when hard resetting it does not have enough time to complete before turning off again. Soft resetting just continues the process.
Trying the whole convoluted 'disable usb connections in activesync, then use a usb port sniffer' method also doesn't work, because the phone doesn't stay on long enough.
When plugged into both the computer and wall it has the orange charging light on, but other than turning on uptil the vodafone screen and vibrating a bit, pressing any button does nothing.
Thanks in advance even if no one can help - it'll help me kill time till I can be bothered to go all the way to the vodafone shop!

I've experienced this before and it is happening because the battery is too low to power on your device.
Plug it in to the wall charger and let it charge. It may turn on by itself and then shut down due too extremely low power but if you keep it plugged in via the mains Charger (wall charger) it will get enough power and you'll be back to normal.
joker, if it started the hard reset process and then restarted before the hard reset was complete, you might need to either redo the hard reset process or go it into bootloader mode and re-flash your rom.

This is the way to handle indeed.
Just let it charge from the mains for a while (15 minutes should be enough) before powering it on.
USB just does not provide enough power to charge your device, I have my TP2 on USB throughout the day, and the battery even slowly loses charge as my laptops USB port simply cannot provide enough juice...

Thank you so much guys - it works, and now I feel like a right idiot haha. Well thanks, I'll learn to charge it by mains from now on .

Depends, but certainly regardless USB provides less current than the supplied charger does.
I have multiple laptops, a few of my own at home, several here at work of various makes and models, and it depends.. One in particular seems to provide as much current over USB as the AC charger as the phone charges as fast as I'd expect it to there, others as you say barely charge the phone at all unless it's idle and off. Most of these laptops however do charge the phone, just slowly.

Plugging in usb cable will automatically start phone

I've been going nuts with this problem, that if the phone is being charged with usb cable plugged in, when I press "Power off" the phone will shut down and automatically restarts itself.
If I unplug the cable the phone can power off fine, but when it's in power off state, as soon as I plug in the cable, it starts itself automatically just as if I pressed and held the power button which I didn't.
What's going on?????????? Please help.
Clarify: it's not that the screen turns on, it's the phone actually turns on / boots / starts.
EDIT:
Did a little research, my problem is the same as here:
http://forum.xda-developers.com/showthread.php?t=1209918
http://forum.xda-developers.com/showthread.php?t=689248

I noticed with mine, the only time it started up automatically was when I didn't have the USB cable plugged in fully to the wall charger.
I think that the phone can somehow detect either resistance or capacitance changes in the USB connection and turns on under certain circumstances, while it is supposed to stay off if the resistance / capacitance values are "normal".

it's normal for the screen to turn ON when you plug in the USB cable
it's NOT normal for the Phone to turn ON from OFF when you plug in the USB cable
the normal behaviour for when the Phone is completely OFF when you plug in the USB cable it should just show you the green battery meter charging

The phone turns on.

maybe it's a defective unit?
have you tried going back to stock?

I doubt it's a defective unit because it used to be fine. Just happened yesterday.
Everything is stock right now.

try a different charger/cable. if it still happens return it.

I had this problem after wiping my battery status and draining it all the way down. After charging over night, I then ran battery calibrator the next day and when i ran it all the way down again and plugged it in the problem was solved. Hasnt happened since (since 2 days ago when this happened anyway).

very interesting

Mine turns on when I plug in a usb cable while the phone is turned off following a battery stuck at 100% condition. In other words, if my phone is stuck at 100% (usually every time after charging), and I turn the phone off, and then plug in the usb cable, the phone will turn on by itself. But if my phone is not stuck at 100%, and I turn the phone off and then plug in the cable, I get the green battery.

one problem with htc one m8

hi all i just got htc one m8 second hand used... lollipop 5.0.1 was already pre installed . so i did a factory reset charged my phone but i noticed a problem with phone that when i restart my device the phone do not automatically pick network signals i have to turn on the Aeroplane mode and then turn it off then my phone captures signals... i have restarted my times but the same problem occurs every time... what to do??
And one more thing to ask please.... the original htc charger i got with phone which is 1.5A charger is too slow to charge it is saying me that 3.5 hours until full it is charging 1% in 3 minutes so i tried another Samsung 2 A charger and that is much fast its charging 1% in one minute so my question is that can i use 2A charger for my phone? will there be any problems or is it effect battery??

I also got a HTC M8 used and when I connected to the charger it was taking 3+ hrs to charge. However, after reading about charging time problems, I did some power cycles (turn off phone, connect to charger for 10-15min, then press Vol up + Vol down + power button. Keep them pressed for a good 2min. The phone will boot and reboot during that time. Then let it boot normally and let it charge). After I did this, my charging went from 3+ hrs to 1hr 30 min with the same charger (I charged it from 5% to full). Hopefully this will help charging time, if not, try different charger / USB cable.
As for wifi problems, make sure you are running Lollipop firmware for your ROM as this is usually a culprot with WIFI problems. If you are, I would suggest flashing another ROM to see if it fixes.

Update: i solved my first problem by soft re setting it three time that is press and hold power button plus volume up button for almost 30 seconds it restarted 3 times and now everything is fine.. it is capturing signal automatically.... now please tell me about my charging problem.. charging is very slow like 3.4 hours to complete charge... should i use 2A charger??

Sorry, I thought you were having problems with wifi. Glad you got the signal worked out.
As for the battery the power cycles I described (and you seemed to have made) should fixe the problem. Just charge it normally after you do them and by the next charge it should hopefully be faster. It worked for me

ok thanks in case if it is still slow can i use 2A charger?? will it effect battery?

I use a 2A charger. I think the phone takes whatever it needs. Ive always used it on my previous phones with no problem. I usually make sure its from a trusted brand tho

Unexpected symptoms, need help assessing and figuring possible solutions

First time posting , I guess, usually I just browse through for info... but now I feel a bit in a dead end.
Spent a few days snowboarding with the phone in pocket, so exposure to cold subzero temp. lowest around maybe -10, only symptom during that period was camera started flickering showing purple lines but worked fine later on.
Also had trouble charging one night, as phone spent entire night being plugged in only to show it was discharging the whole time, and battery low in the morning, couldn't get it charge even after cleaning port making sure its clean and dry.
Phone ended up running out juice and powering down completely... it didn't respond for hours (tried different chargers) but than suddenly the power bank I use showed it started drawing about 9V and 0.1/0.2A for some time and it slowly started drawing more power and charging to 100% took more time then usual...
Next time I tried charging it when it became low around 20% it wouldn't charge from the wall charger or battery charger.
Tried a lot of resetting, rebooting, but the battery just started dropping really fast each reset.
Plugged it in and tried the volume up/down, power button reset but all that did was a multiple resets and still wouldn't draw charge from anything.
In the end it just stopped responding to anything.
I would show a few orange flashes when I plug it to something and than stop.
Tried leaving it plugged in all night but nothing. Leaving it alone for 3 days also did nothing.
Then it stopped even showing the few orange blinks.
Current status:
Plugged it into computer usb and started showing orange flashes, decided to leave it plugged in.
Showed on screen the battery and 0% after a few min. Screen brightness increased after 20min.
Now its been 3h and its still only showing 0% for battery and flashing the orange light every few seconds, nothing else.
Will go to sleep now and leave it plugged in computer all night.

Have you tried a different USB cable & charger?
There have been numerous reports in these forums concerning charging issues with the device. If you've cleaned the USB port on the phone and have tried multiple USB cables and chargers, then most likely your battery is the culprit and needs to be replaced.

In a lot of cases they managed to restart the phone...
Yes I did that. Phone is still showing 0% battery after being plugged in computer usb, I find it funny how it wasn't responding at all to the wall chargers. Now for the question of the day, can I have the battery replaced without losing data? I asked a service center that kinda could be a HTC representative but cannot confirm it and they insisted that they have to do factory reset.

Can you charge the phone up and get the phone to boot to TWRP? If so you can mount your phone to your computer and back up all of your files on your internal storage to your computer.

I don't have TWRP but I just did manage to enter the stock recovery? and its just sitting there not really charging up but using 9V and 0.4A to stay powered up in that mode.
Can you tell me if I go to service center to get the battery changed will I lose all data by default of that process?

I wouldn't think that merely changing the battery would cause you to lose your data, or why they would do anything to your phone that would wipe your data from the phone.

Alright, that was my primary concern, thank you. The service sector where I live is pretty bad, and they do stupid stuff, follow stupid rules.
Update: I switched through a couple of chargers, and tried going into recovery after which I initiated a restart, phone booted normally and showed 24% battery, now is connected to original QC 3.0 ... and charging up, but stopped after 1%, I unplugged it and plugged it again and it continues to charge now with steady orange light? this is really nerve wrecking... what is the real issue? battery, charging port?
My goal is to try to charge 100% back up everything and then I can send it service.

Phone died over night, won't turn on. Any help?

My LG G7 seems to have died over night. I left it on a Qi pad to charge and after I woke up this morning, it was completely dead. I could not turn it on with the power button ow Vol- and power button. The phone shows no reaction.
I thought that I might have misplaced it on the charger (The phone is quite picky with the right spot) and plugged in my USB charger for about 10 Minutes until i tried to start it up again. No reaction. Tried Vol+ and Power and also Vol- and Power with no luck.
Then I started to investigate and plugged a USB power meter in between phone and charger.
My first try was a cabled USB connection, the power meter shows 5,1V with about 100mA (varying between 90mA and 110mA) and I left it charging for about an hour. Still no luck with any method of turning it on.
Then just to try it out, i placed it on my Qi pad with the power meter attached, which got me 9V with about 200mA, so the Qi hardware apparently is transmitting power. Also left it there for about an hour, still no luck.
I noticed some kind of buzzing sound coming from the phone while charging, if I place my ear directly on the phone. A similar but different noise is emitted by the phone when it is not charging and I hold the power button.
Does anyone here have an idea which might return the phone to life?
As I still have warranty, I consider sending it in. I have backups of the important stuff, but I would really like to avoid sending it in with all the private stuff sill on the internal memory...

What happens when ypu plug it into your pc?

+1 same problem.
Nothing show up when connecting to pc. (no mtp,adb,9008 and etc)

Long press vol- abd power button together
