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.

Note II shows Charging 0% and heating up

Hello to everyone,
I have a Note II since 3 weeks. After putting the phone to wall charger, wait until screen shuts off and then bring the screen on again, (by pressing power button or Home button) it shows "Charging 0%" and the battery icon shows empty. Also, the phone heats up right below back camera. And finally, if I unplug from charger, it shuts down by itself.
Also, when on, if I leave TuneIn radio open, after screen goes off it shuts down by itself in max 2 minutes.
The following operations have been done to the phone:
- took it to service and they just reflash it with stock firmware 4.1.2 ORO
- did a wipe / reset to default
- removed the SD card
- no application installed after wipe / reset
- replace the battery with another one, same thing
- installed MEM check and this CPU verifier from PlayStore and they report the phone is not insane.
All the above had no effect on the behaviour. Calls are OK, except sometimes I find the phone off sometimes.
Does anyone have any opinion, is it hardware or software issue?

More of a guess but have you tried another battery it could be defective not charging causing the heat up.

i have this problem too its just human error i think because it happens to me mostly when i let the battery
go all the way to 0% then charge it and try turning it on or using a wrong wall plug .what i do is remove the battery so it completely turns off then put it back let it charge for about 30minutes then im back

Great point, I've tried to power up a completely dead Motorola Droid a while back via USB and it wouldn't powerup because the USB port on computers only put out 500mAh vs the stock 850mAh charger that the phone came with. Once I plugged it up to wall charger, it was able to power up immediately and charge.
The same argument can be made for the Note II if you aren't using the stock charger because the stock charger puts out 2 amps (2000mAh). Most phone chargers put out 1 amp or less and if we are talking about accessory chargers for products like bluetooth devices, you typically get a 500-600mAh charger.

Had tried with another original battery (as mentioned) and no change.
Used all the time stock charger, also tried another charger, still the same.
Took it back to service, hope for the best.

SOLVED! It came back from service and they have replaced something called "flex". Now is OK.

[Bricked] Flat battery, Won't charge, No recovery, No root

Hello all,
I'm at my wits end to put it lightly... I have the P-605, I was trying to flash ng1 official firmware through Odin v3.09, which the file in question, I have used a few times before so it isn't a bad download.
It got about half way through and died. The tablet still boots to the 'firmware upgrade has encountered an issue screen', I can still enter download mode. One major issue I can't charge it and i have no recovery [emoji22] its now dead flat.
Even with my 2.1Amp tablet charger it boots for a few seconds and dies. I've tried multiple cables and USB wall chargers as I thought that may be the issue all to no avail! I am completely lost. Any help would be muchly appreciated

What was the firmware before you flahed the stock ng1? cm11?
Have you try to flash recovery with Odin, don't let it boot up and see if you can boot into recovery.
Did you try to flash with low battery juice??

The prior firmware version is unknown :-/ but it was X KAT v3. I did try to flash recovery but it resets before it gets it done, if I hold the PWR, VOL+, HOME the screen seems to light up stay black a little longer than if it was going to the firmware issues screen then go to 'firmware upgrade has encountered issues' screen. It seems the longer I keep it off charge the longer it takes for it to reset next time its plugged in, so I will leave it for a hour and try to flash recovery. I didn't know what the battery was at 'probably very low' as I haven't used it in yonks and it was already in a bootloop from flashing X Kat v4.0 incorectly otherwise I would have charged it

I'm thinking about taking the battery out and manually charging it with a old USB cable. From pictures on the internet the battery has 2 red 'positive' 2 black 'negative' and 2 green. I'm unsure of what the green cables are. Is there anyone that can shed some light on this?

Hi,
have a look here for the USB pinout !

The original cable uses only four of the micro usb pins. The second ground pin is missing. This can be used to put the device into certain modes. I used different cables, all with five pins, no problems, but it does not mean, that the fifth pin was wired in these cables. Batteries have an internal security circuit which cuts power vis a polyfuse, if the voltage drops too low. The fuse should be re-armed when connecting the device to the charger, although the device may not recognize its own battery. Let it charge for a while, that the fuse doesn't blow again when disconnecting. Plug in again to charge fully. Some devices have a design fault which makes them unable to recover with a discharged battery. Charging Voltage is not 5, but 3.7v! The additional cables at the bsttery are either for a dumb temp probe, or a bus to communicate with the security circuit. The latter maybe impossible to charge externally. Otherwise you probably need some professional charging station, which can handle all sorts of Nimh and LiOn batteries AND have to make an adapter for the custom battery plug. Too much hassle, right?

Get one of this usb filter charging adaptor and use your pc to charge it. This also allow you to charge your tablet using any power source like PC, car charger etc... you will not see the X mark when using your pc to charge.
http://www.amazon.com/gp/product/B007IXBTCK/ref=oh_details_o02_s00_i00

This adaptor adds Apple signaling for charging currents above 0,5A. If the current charger won't support Apple stuff.
And yes, I suspect that the Note expects the Apple signal for 2A iPad charging.
I don't know whether there are any supported charge modes in between, like 900mA, but it charges from a standard 500mA usb port, but only in soft-off and idle deep sleep, and ultimatively slow.
But then, since the KK update, some people's Notes charge only during active state.

I have the same issue.........!!!
I'm lost at this point and dont know what to do.
Any attempts at flashing appear to be useless as there is now zero battery and it wont charge.
It boots straight to 'Firmware encountered a problem screen'. I can get it to the download screen.
It also made it 47% of the way through a recovery via kies, but i think the battery issue caused the failure.
If the cable is pulled out while in the firmware encountered a problem screen it instantly dies and wont start. It wont start unless the plug is in........

Anyone??? Please???

With zero battery, you can't perform any maintenance requiring a usb connection.
Without OS and/or custom recovery, i don't know any advice.
ADB and probably Fastboot operations can be performed via wifi, while the thing is at the charger, but in brick state this won't help.

Thank You
Advice to is find a way to Charge the battery then attempt other methods.
I think Kies may work if I have Charge
Cheers

Maybe the Note froze and drained the battery till it's safety circuit kicked in.
Then you should leave the Note charging for a while(hopefully), to reset the circuit's fuse and get enough juice to not trigger it again immediately. Normally, after unplugging and replugging, the battery should get recognized again and charge normally till full. Monitoring charge in Off-State requires(only) a working kernel, i think.
It also could be a defunct usb jack or just the connection with the main pcb is loose, which is typical for the Note, like loose display and backlight cables.

Thanks Lecorbruiser.
I have had the unit aprt a few times to verify battery connections and all ribbon connections on the boards are ok.
Im note sure of the safety circuitry uou mention though.
I have also power the device up with out the battery plugged in at all. So i know the supply is there. Maybe i have run the battery too low to recover?
Sent from my SM-G900I using Tapatalk

The safety circuit is in the battery or attached to it. Once its fuse has been triggered(normally at 2,5v), the battery shows zero voltage & open circuit. Current from a charger should reset the fuse and the battery will charge unless it had been discharged below 1,5v.
Normally devices with 3,7v batteries are shut down by the system at 3,5-3,0 volts, mostly 3,5 like the Note.

Well the device started to flicker and couldn't keep the screen back light on when it go low.... I'd say I have trashed the battery then if it got below 1.5?!
I have left it on charge for over 10 hours a couple of times and achieved nothing

Android shuts down at 3,5v, in case of a freeze(which could go unnoticed if it happens in standby) the circuit at 2,5v. Then it's a matter of self discharge, till the battery reaches the critical point of 1,5v.
The flickering backlight denotes one of the other cables running across the battery, like that for usb.
I think the connections loose by holding the note in your hands, pressing on the backside. A case with a stiff back will stabilize the Note, like mine. Otherwise all pressure goes thru the flimsy back and is applied on the battery, the metallic shields or some spacers. And the cables get bent very slightly during pressure. Should be harmless, but seemingly isn't.

I have done some testing... here it goes:
Battery Voltage disconnected 2.69V
Battery Connected and USB connected 2.8V
Battery not connected or ( after accidently) shorted 1.5V
From my reading android min voltage is about 3v?
Normal voltage from 3.7v to 3.2V and Charging voltage at a max of 4.4V
I also see some talk of 2.7V figure as a minimum cutoff point, this maybe why it will not give 4.4V to charge as below 2.7v maybe considered a write off?
Thanks for your info lecorbusier

With some custom roms, but none i know for the Note, you can modify the shutdown voltage, to squeeze out a couple of minutes battery life, though the voltage goes down rapidly after having reached 3,5v.

8.4 not charging while on

This isn't the usual "won't charge to full" issue i have been reading about. The tablet is not seeing power connected. Settings>Battery does not show charging. Tasker does not see power connected. HD Widgets does not show charging. Battery bar does not show charging. Ampere (app) shows discharging.
So I did a shutdown and connected power. The tablet does a thing where it shows the battery on the screen and the red & yellow kernel stuff. Then it shows the other "flat" battery icon. Then the display blanks and does all that again and again.
I did try several reboots, hot reboots, soft reboots, long pressing power reboots.
I see an increase in battery level after it is plugged in while completely shut down. Ten minutes got me 4%.
And yes, two known good power cords on two known good outlets. Verified by connecting my phone.

Sounds like a strange issue, if the battery is dead but you are using the tablet then perhaps it is getting power since usually it will shutdown when battery level is past a certain percent (unless it is plugged in), so if that is the case there might be a few things to try
first try to hook it up to your pc see if it detects the tablet (just to make sure the usb port on the tablet is working properly) if so then that's a good sign.
if the usb port is working correctly it could be the wire connector on the actual battery inside the tablet it might have just come loose since it's just a simple press down clip that holds it inplace and a drop or other hard hit could cause it to dislodge, see the thread on how to open the tablet if you want to check, or if it is still under warranty it might be better to send it to samsung if you are uncomfortable opening the tablet yourself
http://forum.xda-developers.com/gal...eseating-battery-wonder-battery-life-t2944610
Now if the usb port is not working or it's not even keeping the tablet powered on it could be anything from a failed charging mechanism, broken usb port, ...etc and probably only Samsung service center can fix it.

The battery is about 75% now… powered off until I can get more info. I am using genuine Sammy chargers and they still connect snugly. Note that it does charge when powered off.

So after an extended power off period I rebooted and charging is normal again. Still considering checking the battery connection. It has always charged slower than I would expect.
