HELP!! PHONE WON'T TURN ON

So I upgraded to the latest mr clean rom and did some tweaks with the registry Wizard. I was playing around with it for a while and turned it off to charge overnight. I wake up and try and turn it on and nothing. I've tried soft reset, and hard reset and it doesn't turn on or do anything. When I plug in my charger the light on my phone doesn't even come on. PLEASE HELP. WHAT CAN I DO!!!.

It seems that you bricked you phone mate. I think that you installed MrClean rom in a G4 phone so you irrimediably f*cked up the bootloader (IPL and SPL). Many users have reported that their phones were able to boot (and behaved normally) immediatly after the flashing but were dead after they turned them off for the first time, this is what happened to you.
Only thing you can try is going to bootloader mode (but i think it won't work since you messed the bootloader) and then flash a new rom. To do this, press and keep pressed both the keys on the right side and then insert a pin in the reset hole briefly. If the phone goes to the tri-colors screen then you're safe, if not continue reading.
If your warranty perior is not yet over then you can have a new phone for free (DON'T tell them that you flashed an experimental rom!!! Tell only that it went off suddenly or that you were installing an official rom!).
Service centre can repair your device (i suppose they've some method to reflash the bootloader) but i don't know how much they'll ask you.
Try asking other users on this forum. Sorry!

...did you ry to recharge it with the ----ORIGINAL 1A CHARGER----? looks stupid, but i resuscitated mine just before throwing it in the bin. if it works, i will explain you the rest....

yup, I tried charging it with the home charger and still nothing. My battery reads at 3v and it's supposed to be 3.8 so it's not out of juice, but maybe it's just dead?

...you can try with just a normal 9 VDC battery, in order to boost up the voltage, to connect it for a few seconds to the ppc battery till you reach the 3.8 VDC and see if it's working...

Ok, i did that...and amazingly it turned on so I pluged it into the charger right away. Windows booted and about 20sec later the device turned off and won't charge again. So i tried again and the same thing happened. Do I need a new battery? TIA

This is waht you need:
http://www.thetravelinsider.info/phones/cellphonerecharger.htm
This charger is somehow wired weird... it charges the battery AND feeds juice to the phone at the same time (believe it or not, regular chargers and USB cables do not engage until the OS is loaded), allowing you to turn the phone on and in a few minutes plug it into the regular charger to continue charging. Just make sure you get the RAZR tip.
It has saved my ass more than once.

I fixed it , What I did was zap the battery with a 9v battery in 3 sec intervals, I did this about 5 times, then I pluged my phone into the charger and turned it on, the 9v gave it enough juice to boot up and the usb took over from there. So to everyone out there who is having this same problem, try this but don't over zap, check your battery with a multimeter.

im having the same problem----my MDA went dead last night because i forgot to charge the battery and then i went to plug it in the charger but the phone doesnt turn on no more...the light doesnt turn on like if it would be charging and i left it overnight and it still doesnt work..... do yall think that its the battery or is the phone just messed up and cant use it nomore????

Last time I had my battery completely drained, it wouldn't charge from laptop via USB. I read something about how the device's "smart-charging" function itself needs a bit of power to start-up...
but anyways, I couldn't charge the battery through the phone (software charging) - what I had to do was to take a USB cable, cut out one end, identify the +/- (red/black) wires, and charge them directly to the battery's two poles (metal plates). It took about 10-20 seconds of charging until I had enough power in the battery to place it back in the phone, start WM5 and charge it thru the phone.
It would have been much easier if you have a battery charger.

I had my phone connected to the computer through the usb cable, and I just left it connected for a week and it was completely dead and could not be turned on. I don't know how it drained the battery (probally by leaving the wifi on, but the computer was in use all the time). Anyway, thanks to this thread, I used the ac charger and it turned on.

thanks for infos

I'm going to give this a go; a Crossbow ROM flash went horribly wrong last night and in my attempts to repair it (I also must have flashed at least 9 times) the phone went dead. It won't charge either, but battery voltage is 3.7 volts, and I'm sat here wishing it was 3
Will get back to you all!

To update: no... it didn't work! I hooked the battery up to a computer power supply (nearest thing to hand) on 5v and 12v and the voltage increased to about 3.81V... I guess the battery is not the problem with my phone, though the symptoms were the same :-(
Any buttons I can press (i.e. like the voice command button for bootloader) to wake the damned thing up? It's probably fried.

My phone has a hardware problem with the on / off button (doesn´t work at all), at the beggining I thought it was a software problem and I tried all sort of tricks, then I gave up and recognized that was a hardware issue and I found 2 ways to turn the phone on 1) When is totally off (This happens when I have to remove the battery to change SIM card) I connect to the USB cable to my PC or to the car or wall charger and I make a soft reset. 2) When I see the phone signal led blinking I remove the memory card and wakes the phone up (not a good idea since I know that the card is going to get damaged sooner or later).

I just got a G3 wizard from a friend a couple days ago. On Thursday I upgraded it to XDA Mobile 6 and left it on the 2.25.11 (I think) T-Mobile Radio that the T-Mobile 2.26 firmware flash put on it. I used it all day on Friday and then I held the power button and shut the phone completely off for 25 hours, but left it plugged in to a usb to 110V AC adapter that came with my Dell Axim X50V. On Saturday night I went to turn it on and it would not come on no matter what I tried. I found this thread and checked the voltage on the battery directly with a multimeter, 3.13V. I cut the head off a usb cable and then held the black and red wires to the positive and negative terminals on the battery for 2 minutes with the head plugged into a front USB port on my PC. The multimeter then read 3.7V. I put it back into the MDA and it turned on, booted and informed me that the battery was completely drained. I plugged it into the USB to AC charger and it read 10% battery on BatteryStatus. I have left it to charge and it is currently at 60%.
I guess the lesson here is to not totally shut the phone off and let it sit, or the battery won't charge, even plugged into my charger. I guess the OS needs to be running in suspend mode for the charging circuit to run. I know I won't turn it all the way off ever again unless I have my little plug thing and my laptop with me.

(old) Nokia phones have a state called "Acting dead" (from service manuals) which takes place when phone is turned off and battery inserted. It means that the energy is flowing around the board so that the responsible hardware keeps waiting for a 'HIGH' signal ordering to turn ON the phone.
When batteries go bellow the 2.x volts they stop being charged by the phones. This is why i protect the battery terminals with tape when the phone is stored for some time and the reason why a lot of people thinks the phones are broken when not used for months. I usually use the 'freezer trick' where i leave the batteries inside the freezer all night and charge them next day.
just 2 cents...

My Wizard XDA got discharged over the weekend and wouldn't start up - after 12 hours on USB it still wouldn't start.
The charge tips saved my bacon - I modified a USB cable as per the instructions above, and used it to charge up the XDA battery - it only needed five seconds and the phone now boots!
Thanks All, great information!
My 2 cents...
If you're going to try the same, connect red usb to the +ve terminal of your battery and black USB to the -ve terminal of the battery. I'd suggest having a voltmeter to hand to check battery and supply voltage.
Disclaimer - the ablve worked for me, but I'm not responsible for anyone damaging themselves, their PC,their phone or anything else by using the above info!

BUMP! thought my phone was dead, hacked a USB cable and i'm back in business!!!!

TYTN II won't turn on
i left it plugged in all day and when i tried to turn it on it didn't respond. i have a second battery that was fully charged and that didn't work either. i tried a hard reset with it unplugged and with it plugged into the charger. nothing works. i'm on the standard at&t rom with lots of programs. i got it unlocked so i can't go to at&t.

Lost all signs, phone doesn't turn on anymore(even on wall charger). Is it bricked??

Folks,
I was flashing CUSTOM__RUU_Wizard_1050412_WWE_101_11210_WWE and the battery went down. The flashing procedure stopped at 85%.
After this incident I could not turn on the phone again. It spent all night recharging and nothing.
What should I do?

SPL 3.08
Wizard Love Rom

Did you charge it over night with the wall charger or with the sync cable? If Windows doesn't recognize the phone, as it might not since you were in the middle of flashing, it may not provide a charge through the sync cable. You might have just thought you were charging it but you weren't.

I was charging with the wall charger, and nothing happens at all (no lights, no bootloader)
Did I brick the phone?

Is there a way to brick the phone while flashing this rom and losing battery power or it's not bricked?

Try pulling your battery for 10 min or so and then put it back in. Phones don't usually get bricked by getting interupted in the middle of a flash. If they did, there would be a lot more people around here with bricked phones because I've see a whole lot of threads in here with people saying they got interupted in the middle of a flash. I don't think you should start worrying about that quite yet.

So I'm taking off the battery for a while, let's see what happens...
I can't see any signal even if the battery is out, and the wall charger is plugged anyway.

I've pull off the battery for about 20 minutes (battery was in refrigerator at this time) and nothing happened.
Is there anything else to do?
(ps:I'm not using the original wall charger...)

OK here's the solution.
First of all, be aware that the MDA can NOT charge unless the OS is fully loaded. If for whatever reason your battery gets fully depleted, you have to do the following (it involves ruining a 5 $ cable and doing some surgery):
- first, go out and buy a new USB-to-mini-USB cable, unless you have 2 already (or one and the original charger)
- take out the battery
- take the USB-to-mini-USB cable, cut off the mini-USB plug and expose the four wires
- strip the red (+) and black (-) wire and twist the copper ends of each wire
- now CAREFULLY attach the right wire to the right connector on the battery (so + on + and - on -) and tape it there so it stays firmly on
- put the cable in your (running) PC or put the charger in the wall socket
- let the battery recharge for an hour or so, then put it back in the Wizard and reboot
- now when it is fully rebooted, you need the second cable to charge your Wizard completely, the way you're used to.
Worked for me! I've kept the ruined cable, just in case it happens again.
Good luck!

Hope that works/worked for you, let me know if it does.

I made the cable, tried to recharge battery for 1 hour nd nothing again...no lights, no signs...still with a dead phone...
Does anyone have a suggestion?

Do you have access to a volt meter? If you do, check and see if you get any voltage on the battery at all. Maybe your battery is shot. Theres no reason for your phone to be bricked so I wouldn't give up just yet.
Theres also another trick that someone else having a similar problem in another post reminded me of to jump start your battery. It involves a 9v battery and a couple of wires (bread ties will work if you don't have any wires laying around). It's pretty much the same thing as the charger thing to an extent. You take the 9v battery and attach the wires(bread ties) from the - to the minus on your cell battery and + to + but only do that for 10 seconds and then remove them, wait 30 seconds and then do it again for 10 seconds. Repeat that 10 times and then put the battery back in to the phone and connect the charger. If that doesn't jump start it your battery might be gone for good.

Thanx, I'll try it too.
Maybe tomorrow I'll have access to a second battery with a friend of mine.(fully charged and working battery)
Do you know why is the phone not showing any lights? Is there any explanation (for the case it's not bricked)?

If the battery is completely drained it won't take a charge (this is actually a well known issue with wizards) the charge lights won't come on because they are actually taking their current straight from the battery.

if you not using charger that came with phone thats probably your issue charger that came with phone is 1amp most secondary chargers are 500ma

I think the phone is really dead now.
I´ve put my friend´s battery in my phone and nothing happened. (no signs)
My battery worked with my friend's phone too...
What are the solutions now? A new motherboard?

I've just reread your initial post and i think you're both guilty and unlucky. Guilty for acknowledging the RUU warning about using a charged battery (check boxes) and unlucky because the flashing might have stopped while writing to the IPL zone.
So i do think that new board is the only solution here. Sorry.

Where are cheap boards for sale?

Urgent help about the battery

I posted this question before, but no one answered. But this problem drives me crazy!
My Kaiser turned off when the battery was running out.
When I connect wall power to charge it, the orange LED indicates it was charging, but just few seconds later it automatically boot, and the orange LED was off.
The problem is, it can't boot into OS due to low battery(it only shows "Smart Mobility", but can't even enter bootloader mode) And only if it boots into OS successfully, it can be charged.
Anyone met this problem on any other devices before?
How can I stop auto boot when charging?
What can I do?

That must be something specific to the rom on yours... mine does not automatically boot when when power is applied (assuming it is off, not just in sleep mode), and it charges fine when powered off.

I use the ROM from this forum
RUU_Kaiser_HTC_WWE_1.56.405.5_radio_sign_22.45.88.07_1.27.12.11_Ship
What is yours?

I'm just using the stock AT&T Tilt rom.

Here's the fix!
Yes, I've had the same problem a few times on my Vario (Wizard). Very annoying.
Here's what to do:
- Take a mini-usb cable (the one you use for sync and charging from a PC) and cut off the mini-USB connector
- Strip the wires
- Take the battery out of your TyTN
- Carefully connect the ground wire (black) with the ground connector (-) on the battery. Fix it with clear tape.
- Now do the same with the (+) (red wire).
- Attach the USB cable to a running PC and let the battery charge for about an hour. After that, put it back in your phone, you'll be able to boot it up and charge it the regular way.
Yes, it costs you a cable, but it solves the problem.

I think you misunderstood. The problem is that the phone only charges when the OS has loaded completely. So if you really run your battery out completely and there is not enough power in your battery to boot up the phone (read: it turns off again before the boot has completed) you won't be able to charge it the regular way. SOMETIMES a heavier charger (2A) does seem to be able to charge the battery even with the OS shut down, but most of the times it won't work anymore... see below for fix.

Based on this, it sounds like it is starting to charge without the phone booted (orange LED on), but for some reason it then automatically boots up, then crashes because there's not enough power(??)
But if the problem IS that the phone only charges when the OS has loaded, that is also not how my phone operates. In fact, that even goes against the manual, which tells you to plug the phone in (without turning on the phone) and let it charge fully for the initial charge before turning on the phone and allowing it to boot.
Sorry if I misunderstand, but neither way is how my phone operates... it can charge without the OS loaded, and the phone does not automatically boot once power is applied.

Not sure I fully understand what's going on here but, I am wondering if the power on/off button is stuck in (i.e the micro-switch is clicked in and not releasing). I cannot think of any other reason the device would turn on when connecting the charger if the device is powered completely off. ( Except perhaps shorted connections in the Usb port)
Mike

To SteRo:
Thx a lot for the solution, I tried, but still doesn't work.(I charge it more than 2 hours, and still can't boot into OS)
To mikechannon:
yes, it happened. :-( the power on/off button is NOT stucked. And the device is powered off completely.
To All:
Thx for your reply. What I mean is almost what dscline said:
It starts to charge without the phone booted (orange LED on), but for some reason it then automatically boots up(around 15 sec after I plugin power), meanwhile orange LED is off. But it can't load into OS, just re-boot again and again because there's no enough battery. That makes it's impossible to charge, 'coz it's only charged when the OS has loaded completely.
Anyway, I called customer service to ask them replace the battery. I may try to use different ROM and see what will happen. I'll post the result here.

It's also possible that it has nothing to do with the battery or charging at all. I just checked mine, and the charging indicator is lit with the unit off, but it does go out for a bit during the boot processes, then comes back on again. So what you're seeing with the charging light is normal. It may simply be that there's something corrupted, or some other failure with the device, that is causing it to not boot properly, and get stuck in a reboot loop. If so, it will probably do the same thing with a completely charged battery. You may have just been assuming that it was related to a low charge.

That's what I'm worry about,, Coz I can't boot it by SteRo's solution.

okay... they say trouble comes in three's...
Yesterday I flew to Asia, 20-hours with a full charge. No suprises during the trip. Checked email from Narita during the layover, no prob. But after I arrived in Taipei I received the low battery warning. Plugged in my usb-to-usb (notebook to kaiser) cable and "no charge light"!
This morning I plugged it into a ac battery charger and waited for >10 minutes, still no charge light.
Now, at the risk of a battery, I'm attempting to charge the battery removed from the kaiser using the previous mentioned method. In an hour I'll test it.
This afternoon I'll pick up a new battery charger and spare battery.
In 14-months with my trusty TyTN (cht9000) I never once had a problem like this... I'm a little bummed right now...
[update]
okay -- battery is okay and can be charged externally (using the two wire method or an external battery charger). BUT... the device still won't take a charge using either a direct AC adapter or a USB cord. This was also retested after performing a hard-reset. Not a good sign folks.
The charger works (connected to a Trinity), so it's not the problem. They battery works (charged to 45% after 45-minutes connected to an external battery charger). The HTC OS after a clean hard-reset used to work but now doesn't, so it's unlikely it's software related.
I've made no other modifications to the bootloader or SSPL... everything is original stock. Wish I had my TyTN with me right about now...

Sounds like something I had on my previous TyTN:
The power connector was a bit flaky on my charger at home. So when I'd hookup the powerlead it would charge to 10 secs or so and then no longer charge. I had to put some pressure on the connector to have it continue to charge. So I put a ballpen on the powerlead, just under the phone, when charging.
It's a long shot - hope of use. When you've connected the phone to power, and the orange light goes off, try wiggeling the connector a bit - see if that helps.
Hope of use.

Re
OK,
I've got excactly the same problems... I dont want to make you illusions, but you cant solve it and you need to send it back for repair. Your usb connecter on your tytn is broken...
first i will tell my story...
My tytn did excactly the same, shows the led, powers on automatically (normally it don't do that, so it;s not a rom issue) and then powered down in the smart mobility screen. I tried 4 chargers, and 2 battery's. with a full battery it will power on and load windows, but unable to charge. with the empty battery it will power down in the smart mobility screen. soft reset, hard reset, it won't work.
You can check if it's the same problem, by attaching it to your usb on your computer and call up the bootscreen by pressing the camera button and stick your stylus in the soft reset hole. If it comes up with serial instead of usb, then your device usb connector is broken.
BUT, you can charge your battery in a very strange way i figured out. since i am on a buisness trip i need my phone and don't send it back!!!!!
ok, this is what you have to do, plug in the powercable, call the hard reset screen BUT DON'T APPLY!!!! you will notice it will not power down, so just leave it on this screen for a night with the cable connected. you don't see the charging light, but actually it is charging. for me this temporarely solution works fine... but when i'm back in about seven weeks i send it in for repair.
Hope this will help you!

Swiftgs:
Many thanks for your insight -- you are correct, in bootloader mode the Serial shows instead of USB. I just purchased a spare battery (1100mAh, made in Taiwan) and battery charger for US$17. It'll get me through my business trip, but this is disappointing. As I mentioned in my earlier post, I used a TyTN for 14-months (July 2006 to Sept 2007) as my primary phone, recharging it daily via the USB connector and on a desk charger in my office. I can only conclude that if the USB is physically damaged (not evident visually), then it is not as robust as the USB port used in the original TyTN. The strangest part of all is it worked perfectly until the battery level fell below 10%...
FWIW: I purchased the phone through R&D Marketing. Ron Webber quickly responded to my note and gave me a contact at HTC America. I'll follow-up
after I return and report my experience.
Cheers

well, thanks for all of your replies/infomation.
I tried evey possible methods mentioned above, unfortunatelly none of them works :-(
and the most depressed thing is I filnally get a new battery, but it still doesn't work!
So I sent it back to repair, cross figure...

It works
I would like to thanx 2 SteRo for his advice. I am using Qtek 9000 and had the same problem. Battery was empty, and I tried many times to turn on my PPC, but without success. All the time when red light appeared after 10-15 sec display become black and tried to restart from boot again, and it's happened many times. Finally I thought that I just can trow my Qtek, but seeing your recommendation decided to try. I took USB cable cut it and strap the wires. Connecting red on (+) and black on (-) after 1 hour charging I was able to start my PPC, to recharge battery by 100% and it is working now OK. I must check duration of the battery tomorrow, because reason why I discharged battery was automatic turn off of my PPC when it was on around 45-50% battery capacity. Tomorrow I will check how it's working when I recharge battery again.
Dear SteRo you are the king.

Wizard wont start after Low battery

After I googled around i found that Wizard have a problem. So when the battery gets low and the phone got shutdown because that reason, i must use a new battery (or do some hijacking with the cables) to power up the old battery again.
Seems that the usb connector cant charge the current battery if its Windows is not started. This is very weird and stupid, so i dont belive it, can some one confirm ?
Btw, my phone startups until the "Windows" screen when loading and nothing more.

It is indeed true, if your charger is not strong enough. You MUST use a WALL CHARGER, not a USB connection on your computer with an output of 1AMP in order to charge a completely dead Wizard battery.

the interesting part is that... i met one of my friends and he take a look of the battery (i dont know much about electricity things). So the battery was 80% charged...a hard reset finished the job, but took me 1 day for searching for new battery and searching for fix. Seems that the problem was from windows mobile, but i will go and buy a wall charger for any future case
10x for the fast reply

yes, impossible to charge while the battery is completely dry ...
When the battery goes dry the only way (known by me) to recharge it is that I pull out the battery and make contact on the battery using needles to make contact from 5 Volt charger to battery (don't do it if your not sure which one is + ) for about 1 minute and thats enough to wake up the ppc.
this is not the best way, for sure ,,, but it works.

Try the PC reset trick. Take the battery out and unplug the USB. Hold down the reset pin for 20 to 30 seconds. Put the battery back in and try to power it up.
I don't know if it will work. On a PC the circuitry gets some sort of internal power loop going on in the capacitors. Removing all the power and holding the power button on for 20 to 30 seconds will short out the condition. Then everything works fine.

Xperia SP wont respond (no flashing problem or root problem)

Hello my Xperia Sp just run out of battery and shut down.I pluged it in saw the sony logo and when i tried to turn it on it would not respond.
The only thing it did was kept the red light on (indicating charging).I tried pressing the off button for over 30 seconds with no results. Not it is stuck and i cant do anything about that.
Help please.

Nevermind the problem got fixed by itself.
The battery (about 2 % run out and the phone kinda reseted itself.It opened just fine.
So if anyone else gets this problem just let your battery drain itself.

Just to confirm you plugged it into a mains supply? USB from your computer to phone charging is not enough to kick start a totally dead battery.
If you have plugged it in to a wall socket and it still doesn't work, give it some time.
I think the battery and the phone's software combine to stop the phone operating at unsafe voltages, the safe operating range for a standard lithium ion batteries is 3.2-4.2 volts (though android may be different). They spend most of their time at 3.7 volts though and this is why they are described as such when you buy them separately.
If, for some reason your phone's software thinks your battery is at 3.1 volts, it won't do anything until it thinks it's at 3.2. Similarly if a protected battery is taken below 3.2 volts it won't provide any power until it hits its minimum voltage. In theory your phone should have cut out before the protection cut in, but bad stuff happens to good people.
Sometimes a protected battery gets drained so much that the tiny flow of electricty required to power the protection circuit stops and as the ultimate failsafe, protected batteries stop working when this circuit is not functioning.
(I'm talking about standard batteries here, not necessarily phone ones)
Sometimes cheap basic chargers won't be able to get such batteries working, but better chargers are able to send tiny trickles to a battery to start the protection circuit and make such batteries charge again. I'd be very surprised if android didn't take this into account and have some way of ensuring over-discharged batteries with a tripped protection circuit can be charged. That said I'm not sure whether the protection is all software on mobile phones?
Like I say give it some time - getting that first .1 of a volt can take a while when the battery is totally flat. If it hasn't changed after at least 2 hours then I'd worry.

Just to confirm you plugged it into a mains supply? USB from your computer to phone charging is not enough to kick start a totally dead battery.
If you have plugged it in to a wall socket and it still doesn't work, give it some time.
I think the battery and the phone's software combine to stop the phone operating at unsafe voltages, the safe operating range for a standard lithium ion batteries is 3.2-4.2 volts (though android may be different). They spend most of their time at 3.7 volts though and this is why they are described as such when you buy them separately.
If, for some reason your phone's software thinks your battery is at 3.1 volts, it won't do anything until it thinks it's at 3.2. Similarly if a protected battery is taken below 3.2 volts it won't provide any power until it hits its minimum voltage. In theory your phone should have cut out before the protection cut in, but bad stuff happens to good people.
Sometimes a protected battery gets drained so much that the tiny flow of electricty required to power the protection circuit stops and as the ultimate failsafe, protected batteries stop working when this circuit is not functioning.
(I'm talking about standard batteries here, not necessarily phone ones)
Sometimes cheap basic chargers won't be able to get such batteries working, but better chargers are able to send tiny trickles to a battery to start the protection circuit and make such batteries charge again. I'd be very surprised if android didn't take this into account and have some way of ensuring over-discharged batteries with a tripped protection circuit can be charged. That said I'm not sure whether the protection is all software on mobile phones?

The phone was pluged in the wall socket.After this i tried to turn it on (while pluged) nothing happened so i unpluged it to press the off button (i upluged it because i could not reach the button because i had the case on) but the red light ( at the bottom of the device indicating charging) did not turn of.So i tried to reset the device by pressing the off button but i waited for almost 30 seconds (while pressing it) and nothing ... not even a vibration.So i left the phone away with the light stick on till the 1 % left was drained and the phone shut down due to lack of power.
So then i pluged it back in to the wall socket and it started charging again and so i turned the device on.This time it responed and opened up .Now nothing is wrong

It happened again.... i dont know the problem but the solution was the same...

You left the phone in the charger to drain or not? If i put the charger off then red light isn't opened..
Also, how many hours did you wait?

It took about half an hour because of the battery level being low.

Guys im having the same problem.. anyone who can help will be appreciated.
