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.

Shut off when battery is low?

Last night i was using my phone right before going to bed. The battery was at about 18% or so left. I got up to get a glass of water then came back to plug the phone in to the outlet only to notice that the red led was not on. I pressed the power button and nothing would happen. The phone completely shut off without interaction. So I panicked a little and plugged to PC USB cable that was attached to my PC and nothing. wasn't detecting or anything. so I press and held the power button and plugged it in at the same time and it powered on again. Anyone know what could have happen?

Only time i faced this problem was when i tried to drain my battery completely. it wouldn't shut down on its own when it reached 0%, so i turned it off myself.. The next moment is wouldn't boot or charge also. Then i held the power button and it came back to life.. Don't know what the exact cause is though

Yea it kind of turned me off on the phone. But I still love it. anyone else have a similar issue like this? I'm hoping that it is the power management issue that some people are having as there is a quick fix with that. I was avoiding rooting or modding my phone, but I might just have to now.

i'm a noob so i don't know much about most of this, but this really sounds like the way my ipod functions if i let the battery "die." i can't imagine that any manufacturer making a phone with a non-removable battery doesn't have it set up to be rechargeable upon plug in.

Ye, furthermore i've read that this is cause but letting the battery ''die'' indeed, it takes time to charge it back up because when you let it die some kind of undervolting protecting is kicking in i guess and soon after it will start to charge

A Very Bad Case of the Bootloop

I was using my Kindle a while ago and noticed that the battery was going pretty low and not charging right. I hoped that it would resolve the problem by itself, but no. Instead, I turn it on to find it stuck in pretty much a tenth of a second Bootloop. It shows the FireFireFire symbol then goes away almost instantaneously. I cannot think of anything I have done to it. I was using Hashcode's 4.1.1 Jellybean ROM and it was working great. I have a charger that I do not know if it is a legitimate Kindle charger, but before this it was charging just fine. If you could help me, that would be great I would not like to spend another $40 on a new kindle battery. Thanks!

Leave it alone for a while and give the battery a rest for a bit. Then plug your usb cable into the computer first then your Kindle. As soon as it comes on, hold the power button to cause it to hard shutdown. With any luck, it will shut down and stay off. If so, leave it off and plugged in for quite a while; it should charge. If you can't get it to hard shutdown (keeps turning back on), sometimes heating up the battery a little will give it just enough of a boost to make it work.

I can't, I don't have a micro-USB cable and my mom won't let me go buy one...

How did you root without a micro-usb cable?

Please don't post questions in the General Section
Moving to Q&A

The tablet is dead after full discharge.

I had let the tablet with 1% of battery at night.
In the next day the tablet wont charge, wont boot, nothing. It is completely dead.
I had tried many things like let it plugged in the PC, buttons pressed, etc.
Someone knows how to bring back to life the v500?
This is absurd! It's a common situation.

I've been in the same situation.
I let the tab on charge for 2 days : no change
I leave it for a week without anyplug then I charge it again.
After a moment, it's start charging ^^
I don't understand why or how but it's OK.

I had found a solution:
Is to unplug the battery,
wait 30 min,
press the power for a few seconds,
plug the battery again,
plug the charger.
I think the battery needs some time to regain some juice and have the minimum to boot the device.

I had the same problem.
Take the charger off and wait for a short time.
Press and hold the power on button for 20secs. or until the device turns on.
Let the device run its startup process. It will most likely power off after a few seconds or minutes. (This is okay).
Charge the device as usual.

Random reboot hard bricked my Robin

May be unrelated but updated to the latest nightly of Lineage, ran into the camera issues and got some random reboots. Sent an email, and then put it in my pocket, pulled it out a few minutes later and it wouldn't turn on. Have done the hold down power and volume down button to no avail. Used the USB cable to hook it to the laptop, see it in QDLoader 9008 mode. If I hold down the power button and the volume down button I can see it disconnect and reconnect but it never turns on or shows anything on the screen.
Spent a few hours googling it and looks like you need some hardware specific files to the QFIL method, which I can't find. So is this device toast? Was really enjoying the device and so sad that it died after only using it for about 1.5 months.

**UPDATE**
So the leave it plugged in to the laptop overnight trick didn't work. So I took the phone a part, when it's in this mode it seems like there is is still power to system. I left it open until the battery died, and the regulation circuit cut power. Then plugged it in the laptop(although a charger would probably work). Let it charge for 10min and it came back. Seems like it get stuck somewhere in the boot and needs to be reset, but without a removable battery you can't cut power. So if anyone runs across.this, leave it disconnected overnight(or maybe longer) until what ever state it is in kills the battery. Then plug it in and it may come back. My booted after being plugged in for 10min and turning it on using the power button

So I have the same problem with my device and am thinking about doing the same thing. What tools do I need in order to perform this?

I also have the same problem, is there any help?

So this worked for your hard bricked phone? And you had no more issues after?
