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.

[Q] Continuous reset after battery drained to 0%?

I let my phone's battery run out to zero. Then let it sit for a few days, I'm on vacation and I don't need my phone. Now, I am recharging my phone, but something strange happens. The phone is off, and the amber light shows that the battery is charging. After a few minutes, the phone turns itself on and the amber light goes off. The battery does not have enough juice to complete startup, and the phone dies halfway through boot. The battery then begins charging, phone turns on, etc. It's been doing this for several hours now. I can't turn the phone off while it's booting, as the OS to control the keys is not yet working. Any help, I've no idea!

5 minutes in charge should give you about 7-8% battery, enough to get it up and use it for 5 min or so. Sounds like you have a dead battery.

Hmm...doesn't seem possible, the phone is only 2 months old! I'll keep it connected and see what happens. Any idea why the phone turns itself on when not commanded? The problem isn't really the battery, the problem is that the phone won't stay off long enough to recharge fully.

Somebody else posted a thread with what sounds like the same problem -- just a few lines below yours. And devis posted the same answer there -- which sounds like the right answer.
If you have access to -- or go buy -- a new battery, that would be the thing to try.
I'm not a battery expert, but I think it's not a good idea to let the battery -- any Lithium battery -- go down to zero-dead. (That is, you should turn it off or charge it up when it drops below 10%-ish.) That could explain how a 2-month-old battery could die (if it is dead).
Assume you're trying to charge the phone with the AC-wall charger, not connected to the USB port on a computer?

If you can't turn off the phone to keep it from rebooting, I suggest you take out the battery, put it back in and let it charge for a few hours. I would just be careful to not accidentally turn on the phone. Hopefully this will bring your phone back. I read on another thread that if the battery drains completely, it may need to charge for a reasonable amount of time before you can boot it back up.

happens to me whenever i dont notice my battery draining to 0%..
it dies, and i try to turn it on.. turns on, then dies on boot.. plug in charger, and it goes through an endless cycle of turn on and die on boot.
take the battery out and put it back in, but don't push the power button. let it charge for 10-15 mins to let it get enough juice to boot all the way.. then continue charging it

This will also happen when the charger is not putting out enough power such as via usb cable. Make sure the phone is off and use an AC charger if you can.

For the archives, the problem was that the USB port on my computer went bad. I plugged it in to another computer and the phone charged normally. Now I have a broken USB to repair...on a laptop. Should be fun...

If you have the AC wall charger that works better anyway. Some USB ports of some laptops won't work at all -- not because they're broken but because they don't put out enough power -- by design.

thx but still brick...

Kindles don`t just magicly do this. You should provide some details of what caused it to be this way if you would like details on how to correct it.

That looks a dead battery. You're running ICS on it, right? ICS still has the charging bug and it hits everyone when least expected. Yours turns off really fast, which is concerning.
You might be able to get it to charge but it seems unlikely. You'll need to plug it into USB and press and hold the power button at the same time. With any luck, the device will stay on long enough to get a hard shutdown. Leave it plugged in for a while to charge and try to boot it again.
Now, I'm only guessing that's what's going on because I can't see how the device acts when it's plugged in, but it seems that's very likely the case. If it was a dead battery, it would just constantly reboot until unplugged. The key is to get it to stay off while plugged in so it can charge.
If you can't get it to stay off, gently heating the battery up a little can sometimes offer enough of a charge to keep the device on long enough for the hard shutdown countdown.
Hope that helps.

Tablet don't turn on

When I turn on the download mode on my lg g pad it was a low battery charge. The tablet didn't sew and now I cannot it turn on. May you advice me what I can do with my tablet so that it included? Thanks.

Are you saying it won't take a charge anymore? How have you tried charging it?

Yes, of course. I tried charging it, but there is no reaction. What can I do with them?

Okay, on some devices if the battery gets really drained you actually need to try a different charger to find one that may work. As an example my old kindle fire got drained to the point that the factory wall charger would not charge it at all (no reaction when plugged in overnight) but when I plugged it in to a computer and left it plugged in for an hour) it started to take a charge. So the first thing I would do is try a computer (which typically would charge slower) and see if the tablet responds to that. With the kindle fire running android I had to plug it in and leave it in for a while in order to get the device to respond when it was really drained.
In addition you may try holding the power button for 15 seconds or so once it is plugged in this should do the equivalent of a battery pull resetting the tablet which may then let it take a charge...
See if that approach works...

[Q] Battery taking far too long to charge on KF 1st gen.

I am running [ROM-AOSP] Stock Jelly Bean 4.2.2_r1 for the Kindle Fire [02-12 4.2.2_r1] on my 1st generation KF for quite a while now. However, lately the KF takes a very long time to charge (8 hours or more yesterday), and even appears to hang while charging. I have made no changes or uploaded anything that can explain this. (The battery saver App Easy Battery Saver is installed, and has been all the time.)
Can anybody advise on problem/solution?

Change your charging device. If that does not resolve it, then you will have to open the kindle and either replace the battery or check for bad solders/loose wires.

Like bad charging port, but could be bad charger, or bad battery.

okay, thanks for both answers.
I have ordered a new charger, so when it comes I can try that to see if that solves the problem.
What I have noticed today, is that the main orange Kindle Fire "On" light goes out briefly now and again while charging. I don't know if this is normal or not (or if it gives any clue to what might be wrong)? The Kindle is charging now and has been for several hours, but is only at 23% after all these hours. I don't know if I should leave it (and it will stay plugged in all night) or unplug it.

NOT Charger - how to tell if it is the USB Port or Battery?
I should have thought of this before I ordered a new charger (which hasn't come yet). I plugged the KF into computer (usb) and after a while it stopped charging!!!!
So it can't be a problem with the charger!
QUESTION: So how do I tell if it is the charging port or the battery???? (unless a wire is clearly loose then it is not a problem to know)
I did have the feeling that the battery is running down faster than usual (but not sure) and "maybe" even leaking away slightly (less sure of this though)

I know with mine, sometime it doesn't charge, so I disconnect charger from kindle,
I reconnect I press it in with some pressure, and then pull out but not enough that it really moves, and it starts charging again.
I only have a problem once every 15 -20 times or less.
also could try a little pressure from one direction on the cable,
don't want to keep moving it, it can take a few secs to start charging again
don't want too much pressure or you will make it worse.

Okay many thanks for the reply sd_shadow - I'll have to wait with that
I took the back off (first time I've done that) and wanted to see if anything was clearly loose - but I found I don't have a screwdriver that small to remove the board - so will have to buy a screwdriver tomorrow (frustrating) - and don't want to put it back together until I have checked for possible loose things.
However, I don't think that todays stopping charging while on USB/computer is perhaps that important (but I am a novice so??). The other day I did try removing charger cable and replugging, when it did not seem to be charging, and afterwards I saw it was charging, but still going really slow.
As I also noted in my ealier Post I saw that the Kindle On light went out briefly and came back on while charging now and again (on USB/computer today went out and stayed out) - I don't know if this is a usual happening while charging - or if this is some indictaion to a certain direction (loose something or battery)?
Would be great if someone knew this!?!
I don't have enough expereince to know this!
I am a bit surprised that this problem has suddenly popped up - I take very good care of my KF - and it is always protected in a cover, and I am very careful when charging it - don't move it about/Charge it fully/etc. I mostly only use it to read ebooks the last months and switch it on maybe 1 or 2 times a day, and not for that long
I can't help wondering if it could be the Stock Jelly Bean 4.2.2_r1 causing this problem??

problem solved!!!
Sorry for the late reply to this – holidays!
I solved this problem with the help of this person at:
http://www.amazon.com/forum/kindle/ref=cm_cd_pg_pg1?_encoding=UTF8&cdForum=Fx1D7SY3BVSESG&cdPage=1&cdThread=Tx3BVTWI4W8QESI
I recommend that if anyone has a similar problem then they read this before taking other action.
I bought a new charger which I did not need!
The battery charging memory was out of sync. When you put the charger into KF it switches on, and my mistake was that I had been leaving it on. Additionally you need to do a regular charge – but read the above article, a bit long, but well worth reading if you have this problem (or even without)!
Thanks to all

Firehell, the Amazon discussion board is no longer available. Can you be more specific about what you did to solve the problem with the charging?
Thanks

I am having the same issue. Your link does not work anymore. Can you please tell what you did to fix charging issue. Thanks.
