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.

p3300 no power; no charging lights etc. sometimes boots just fine

i have a p3300; no power lights when charger is connected; doesn't power on as well. battery is fully charged, battery and charger are both fine. but sometimes the p3300 powers on just fine; if i connect the ac charger then it also charges the battery. but it hangs in windows mobile 5 after some time (trackball and buttons and system does not respond anymore); after a soft reset no power/power lights or boot at all. then after some time and fiddling it might power on again and the cycle starts again.
i know it is a common problem; but is there a solution?
the backup battery (yes, there is one in it. the same as in the qtek 8310) gives me 0.20 volt. not sure how much it should be. but the backup battery in my qtek 8310 gives also 0.20 volt. not sure whether both are drained or that the voltage is normal.
will a drained backupbattery prevent it from booting up fine? or... hope to get it up running reliable again; great navigation phone with tomtom.

without the battery installed i get a red light flashing quickly if i put the 5volt charger on it; same if i connect an usb cable (connected to my computer);
if i have the battery installed; i do not get a red light flashing.
with the battery plugged in and the charger plugged in; i don't see any charging lights. but it does charges my battery; i started with 3.7 volt, and it is going up (now at 3.9 volt).
in both instances i cannot get it to power on/into bootloader mode.

i've got exactly the same issue
I was given this phone by my brother as its broken, i tend to get alot of his broken stuff anyway i stripped the phone down and found that the little battery inside had leaked so i did a little bit of hack wiring and bodged a 3.3 volt battery used in a PC to power the cmos chip well it seems to have sorted the problem apart from the fact there are two wires hanging out of the phone but i've also noticed this battery voltage has dropped to 2.6 v now and still dropping over the days i'm guessing i'm going to have to make it replaceable.
oh just for the record
my brother tried a replacement main battery on it originally and tried flashing it with a clean rom to try and fix it but it carried on hence passing it on to me

...
...to both of you...
buy a new battery..
leave it OFF while charging!!!
when the green led comes on (orange while charging... red flashing indicates battery is dead)
done.. turn it on..
batterys are cheep on ebay..
(if this dont work, pm me.. it could be something totaly differant but buying a new battery is the usual soloution for this common problem)

Charging Battery Problem HTC

I've tried and installed a few ROM's from this website and since today I can't seem to charge my HTC when the battery is running low.
Whenever i put it on Charge on the cable it won't show the charging icon on my phone and it doens't gain any energy.
This is what happens:
When i plug my phone to adapter the "ring" on the HTC touch diamond glows 3(!) times which means it charges it for aslong the ring glows (3 times). But after 3 glows it doens't glow anymore and which means it stops charging.
Also when the device is OFF and it stops charging after 3 times the ring glows (about 10 secs?) i can press the ON button and it charges it again for 10 seconds. The funny thing is that it also re-starts itself automatically every like .. 1-2 minutes and shuts off again.
Does anyone know why this happens? Please help
Thanks

have you tried replacing the cable, cradle or even the adapter? Check their contacts or pins carefully! Maybe you got dust particles in there.
Oh, does it get charged upon connection to your computer? Are you using the same cable?

No it doensn't get charged when i connect it to the computer. And yes i tried several other cables and connected them to computer and adapter but still not charging.
I really don't know what to do

hey buddy if u r using htc diamond i m sure after changing the rom u wouldnt b able to charge from pc bcoz some cooks use a tweak which disables charging through pc...do one thing download advanced config 3.3 or 3.2 then go to power management u can find a option to enable or disable charging from pc....

When the phone is turned off put it in charge then turn on your phone,go to backlight options and there should be "When device is turned on,do not charge the battery when connected to the PC" untick this then re try

Yep i done that, but my phone can't get charge from anywhere. Not from USB to PC and nor from just putting it in the adapter.
I'll tell what happens:
When i plug my phone to adapter the "ring" on the HTC touch diamond glows 3(!) times which means it charges it for aslong the ring glows (3 times). But after 3 glows it doens't glow anymore and which means it stops charging.
Also when the device is OFF and it stops charging after 3 times the ring glows (about 10 secs?) i can press the ON button and it charges it again for 10 seconds. The funny thing is that it also re-starts itself automatically every like .. 1-2 minutes and shuts off again.
It's a weird problem and I'm really stuck with this and don't know what to do. I'd prefer not paying 30$ to buy another battery if that's the problem. If anyone else has advice then PLEASE give them.

I've used short, long, medium cables, and I've also used different sort of adapters but nothing seems to work.
The only thing that COULD be it is either something wrong in the ROM or the battery.

First time i heard of this.
1) It wont charge from the adapter or the pc via usb
2) The charging led shows action for a short time then stops
When the phone is OFF it should charge regardless of what modifications have been done to the operating system since the OS is not active.
Have the phone inspected especially the mini usb port, i think its not just the battery.
It could be either the mini usb port or the battery or the charging circuit in the phone needs a part to be changed.
It looks like a hardware problem.
On the flipside, wherever you get the phone inspected bring the battery with you and see if it will charge on their universal chargers.
Most cellphone techinicians have a universal charger which will charge any battery even without the cellphone it was designed for.
See if it will fully charge and then insert it into the phone.
Now if the battery did charge fully and the phone doesnt have a hardware problem, then you can conclude that its the rom.
Go back to standard official rom from HTC and observe if its behaving normally.
But im betting there is a hardware problem.

Me either...
Sometimes i get the same problem, but i keep on trying to charge, acn then it do!!! you have to be persistent.... leave the phone pluged int AC over the night... try to remove the battery while charging... one time, it will start charging... THAT IS what happens to me... (after upgrading rom and spl)

Same Problem With my Orbit 2
I am having the same problem. Now my battery can be charged just with the universal portable charger. I take out my battery from Handset and plug it into Universal Charger. Actually my problem started after the uninstalling the Android Nand.
After that I tried different roms but problem is still there.

[Q] Phone not charging, even with AC adapter?

Hey,
(I tried searching for similar threads, but "charging" and "desire" gives me billions of results)
I have quite a sticky situation on my hands. Last night when I were to check my phone for messages, it was turned off. I grabbed my charger with the AC adapter and plugged it in. Voilà, amber led is turned on. I waited a while as I went off to grab food and that sorts, returned and turned it on. No problem so far. Small digression: I even got those messages I expected, hooorah!
Anyways, after a couple of hours I returned to my phone to check additional messages but then again, it was turned off. Even though it was hooked up to the AC adapter. I mean, the amber led is turned on and even the battery animation in the status bar when charged is doing its thing.
So I started trying to figure out what it is, but nothing have helped the slightest bit so far. I tried flashing different radios and roms but the problem seem to stick.
What's odd is that it allows charging sometimes, but it takes a long while. I have yet to find out the reason for it, but my doubts are that currently the phone needs to be off.
So far I think it could be a faulty USB cable that may cause the problem, but even though how obnoxiously stupid it may be, I turn my ears to you guys.
Thanks in advance.
TL;DR:
The phone isn't charging even though it's hooked up to the ac adapter and both amber led and animation in the status bar is indicating it's charging.

first things first,
search xda-developers re: USB brick. does it fit the symptoms?
do you have access to a different usb cable? does it charge better from this one?
will it charge quicker on on (for instance) your computer, compared to the wall charger?
is the charger an official charger or a third party one? if its a third party, no name brand one, chances are its crap. I bought a 1000mA rated car charger and one of the components won't let more than 100mA through.

Greetings, nzdcoy. Thanks for quick answer.
Let's see. As far as I can tell, USB brick symptoms sounds like you're unable to connect your phone using USB when booted into Android and/or custom boot/recovery. I have yet to try this, but I also read that they were able to charge the phone without problems. However, I'll give this a try seeing as it won't hurt.
I'm afraid I do not have access to another USB as these "micro" USB cables aren't that widespread. Or, at least I don't have leftovers as I do for regular USB cables.
It's hard to tell if it charges faster for whether possibilities as it doesn't charge at all if it's on. The amber led is lit, but the battery percentage still drops. I've only relied on the wall charger as I know it supports more amper than its PC counterpart. But yet again, I should try the USB brick fix. Hopefully it'll work.
Both the charger and the cable is stock, so I don't think it could be shabby third party components.
I'm also suspicious to if it can be the battery that's blasted. I've measured the voltage and it seems to be fine, so I don't know for sure. Maybe it's bad because it takes ages for it to charge? I don't have an external power supply, so I can't test this for sure though.
Anyhow, thanks nzdcoy for giving me some directions to what it could be.
Edit: Tried hooking up the phone to the computer, and I had access to the SD card. I suppose that's not a USB brick then?

at least it isn't a USB brick.
Does it positively charge when plugged into the PC? Unless you are using GPS or you are using a USB1.1 port, your PC should still charge it positively.

Yes, thankfully.
I've somehow found a method to charge the darned phone. And I could almost conclude it's a bad connection between the wire and the phone. I think the socket on the phone is damaged. Worst part is, is that it comes and goes. One day it could work swimmingly and charge in whatever position, the other day it requires one certain position to charge anything at all.
My Desire works in strange ways.
Thanks for the help so far, nzdcoy!

[Q] HTC infamous Battery charging bug with M8

Just got my M8 first time I turn it on it had half charged battery. I drained it to a point when I turned it on two times and than it went dead. I mean I could not turn it on. When I connected the charger no light came on and no response from phone. I leave it till toomorow and see if it will turn on.
I fear HTC is using the same chip for controling battery charge in M8 which if flawed by infamous HTC charging bug. If this is the case it is really start annoyng me and htc m8 will be my last HTC phone. I had so far Wildfire, Sensation ,Desire and all off them had a charging bug. Wildfire and Desire would not show the battery full even though battery voltage was at full charge. My luck? Or HTC has some poor quality components? My S2 still charges battery fine till today.
Ok. Anyone can check their M8 if you have charge bug if you battery is almost drained off power if it will turn on or stay dead?
If my won't wake up tommorow after all night at charging I'm gona exchange it on warranty and see another sample has the same charge bug.
Why HTC is not doing something with this CHARGE BUG on the newest devices? Puzzeles me.

I brought mine to 1%, cycled the power, then used it again till it died. Plugged it in, charging icon came on right away, charging light as well. Hope this answers your question, I didn't really read the whole post.

My M8 has just died because it wont charge, happened just yesterday. I left it plugged in over night and still nothing. Its a holiday here at the moment so have to wait until Wednesday for HTC to open.

Possibly The same Problem, Possibly Not?

Hi.
I've been having loads of problems having unlocked, rooted, S-Off, SuperCID & installing the ARHD ROM on my M8 (International) but it was, in a fashion, working. I too am on holiday & whilst I now know why I was having the issues & have the solution to them, I didn't have time before I left to resolve them. So, I brought it away with me to use for basic currency conversion & translation tasks & it was, as I say, functional. Last night, I decided to play a game on it & it was being laggy but I put this down to the issues I've been having, so didn't worry. It kept being laggy, so I tried restarting it to see if that would help but once it had powered down, it took ages to reboot, so I tried using the power button to switch it on. Again, it took ages & I briefly fell asleep but when I woke up, it had booted back into ARHD, so I figured all was okay.
However, when I awoke this morning, the device would not switch on. I plugged it in to see if something had caused the battery to drain during the night but nothing happens; the charging light doesn't come on & it doesn't power up, no matter how long I leave it! It is, to all intents & purposes, behaving as though it is dead (bricked?) but I don't know why it should suddenly do this, which is why I was looking for answers & came across this thread.
If anyone has any bright ideas, I'd be more than grateful to hear them

Mine needed a replacement charging board and chip unfortunately but HTC Vietnam was pretty fast, only took 3 days so wasn't too painful.

I like how "Happened to three people" == "infamous."

Yes, this sounds like a very isolated bug/defect. Since it is not reported by very many, the best course of action is RMA. ?

My T-mobile HTC ONE M8 has done this as well, however I was after serveral hours of trying everything I could think of, connecting it to the computer and various chargers and trying to hold volume up and power and replugging it to charger, it finally started charging. This has happened 2 times in the last 2 weeks.
Now that it's charging I wonder if HTC will take it and replace the charging board or battery. I also worry that I have it rooted and s=off that they won't honor the warranty.

There is something similar to this going on with mine - Was charging (maybe quite slowly), battery very low, phone reset. Booted into charging screen, amber light flashing. After a while (and trying to boot a few times), no light, nothing. Charge current is 0.00A
Edit: I remember something like this with the old Desire - there was a trick to reset the charging circuit, which was maybe locked up and not getting a good po_reset, so never enabling any charge. Something along the lines of unplug, hold some buttons for some time, plug, profit... Does anyone remember this in detail?

I had the issue in this topic, and got it solved.
Here are forums where I have found similar case and solution.

I have a particular case. My phone is a HTC One M8, but I have protected it with a special case with a battery extension, home made. I have assembled myself the batteries, chargers and boosters. My booster has a small issue and does not enter safe mode when battery is low. It warns about low batt with a LED, but still tries to deliver 5V. The booster is connected to the phone via a flat cable, stolen from a wireless charger; those chargers have the smallest USB plus I could find ever, and, I found this plug only in these decvices.
When the main battery of the phone is empty, I switch the booster on, and recharge the phone with the backpack. I have to look at the LED; when it's red, I have to switch it off. Everynight, everything get charged on the same single plug. One plug to charge both batts.
The advantages of my solution are:
- phone can last 18h with heavy work (wifi, bluetooth, GPS, and screen on, continuously)
- heavy case to protect my phone, plus tampered glass
- one plug to charge everything
- the micro-micro USB plug is ALWAYS in the phone. This means, the female plug of phone can not get dirty, or filled with dust. I never unplug it, so it does not age. I never plug a classic USB cable directly in the phone, so, no chance to break it. I have broken 3 or 4 times the back charger plug; if I am in hurry, I can exceptionally charge the phone directly; next day home, I can fix it.
This night, I was using my phone, and switched the backpack on. I could not plug my wall charger, because it's home made, has an issue, and makes the virtual keyboard erratic. I fell asleep with the phone in my hand, and the backpack went red ... for 4 hours. During 4 hours, it was trying to deliver 5V, and failed at so. Since my battery was delivering an unstable +5V, the phone was trying to charge, was staying on, but could not properly charge. In the end, all batteries got flat.
This morning, when I woke up, I plugged the stuff; only the back-batt started charging. Phone itself refused to charge; screen was black, and charging LED stayed off. So, I fell in what we call the "phone refuses to charge".
But, because of my set-up, I can *NOT* be in the dirty or broken plug case. Just impossible. And because of context, I just knew I had a flatt battery. This is technically called "deep discharged". And it contributes to aging of batt. Like overcharging, this heavily affects the total capacity.
I knew I could fix the issue by opening the phone, and putting a LiPo charger directly on the batt lines. I have loads of standalone chargers. I had a standalone wall charger for my previous HTC Sensation. But with the M8, we can not just open the case, and take the batt out. It's much more complicated. So, I have been Googling for more than half an hour. 95% results were about "remove dust of plug" and "bring it to the shop to change your plug". Some people also mention "a bug in the charger chipset".
I have plugged the phone on a classic USB charger, but via an USB meter monitor:
dx.com/p/382581 (dispite description, the device can accept up to 13V on input - this detail is critical when you use real QC2 chargers able to deliver 9 and 12V, like this one:
http://www.amazon.fr/Chargeur-secte...&qid=1451509059&sr=8-4&keywords=aukey+charger
http://www.amazon.fr/batterie-exter...&qid=1451509059&sr=8-5&keywords=aukey+charger
)
The USB meter was indicating 5V 0.03 A (or 9V 0.01 A, depending on source). So, the phone was using a bit of energy, but clearly not charging. I have left it 4h. Just in case, can not harm.
Then, I pressed together power, and volume up. The phone started to boot after 55 or 65s. About one minute; but clearly way longer than 42 or 47s found on forums. It started directly to some rescue mode, then, started to boot normally, without doing anything. Just released buttons during the first white screen. After booting, I have a normal phone. Did not need to perform any action. During boot, the phone had 2% batt, and was charging normaly. But, the charger LED remained off; I waited 5mn, untill I got 4%, unplugged the charger, replugged, and then got the orange LED.
Remember that your M8 can accept up to 9V on input. QC2 Chargers are really faster: with 9V 1.5A, you can charge your M8 from 0% to 100% in 95mn, even if you are intensively using it (gaming, wifi, GPS). Next gen phone will accept 12V. Even if manufacturers ignore that. HTC buys chips, and don't fully read specs. Aukey chargers are more powerfull and better reliable than official HTC ones.
Remember that many "slow charging" issues are in fact due to bad cable: charger is good, phone is good, but cable in between has high gauge copper, too thin wires, and produces voltage drop between plugs. HTC phones require 4.4V at the plug.
Remember that M8 and most modern phones (same for Samsung) are now MHL (wrongly called OTG): they are true USB hosts; you can plug any device on your phone; just buy an MHL (OTG) cable for 4 euros, and then a USB hub, and then any device: mouse, keyboard, USB monitor, ethernet dongle, SATA adapter, CF-uSD adapter ... and for 12 euros you have HDMI converters. Modern smartphones are real computers. Use them.
