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.

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.

Strange charging problem

I installed ICS RUU some weeks ago and all has been well.
All of a sudden now when I plug in the wall charger it takes about 30s or so for the charge led to light up or for the phone to indicate that it is being charged. Likewise when the wall charger is unplugged it also takes some time for the charge indicator to go out with the phone still thinking its being charged.
With the USB cable the PC ding dongs immediately but the charge led will take 30s or so before it turns on and I no longer get the prompt for charge only, HTC sync etc.
In all instances the battery does eventually charge fully.
I have rebooted the phone but same problem.
Any ideas what's going on here?
SOLVED.
I removed and refitted the battery. Back to normal.
Thought I would leave the complete post with solution in case someone else experiences the same problem.

i'm having a problem where i put my battery in (think its completely drained)
the light for charging will flash for about 5 sec then go off
try reinserting again. this time it blinks for a bit goes solid then off after a few sec
try one more time this time its solid for about 5 sec then off again. best i can get it to do. if i do this about 10-15 times the screen led light comes on then off and thats it.
any ideas? is there a way to charge it without it in the phone?

@WK - you could try resetting battery stats. I believe that option is available in CWM custom recovery.
I've seen aftermarket batteries and chargers for the Vivid on eBay.
-RKA

Yes there are inexpensive chargers that you can get for these batteries on Ebay. You may even want to get one including a battery.
Having said this have you tried charging using a USB cable from the PC?
You may have a faulty battery or a faulty charger port both of which should be covered by your warranty.

try this too
try plugging the phone in without the battery connected, boot it up that way if it will let you, and then insert the batt while the phone is on..let it charge for a bit.. and see if that helps. Not the safest method, but it almost sounds like you've got the older recovery with the phone off charge issue.
Hope you get it figured out.
EDIT: Don't bother..i just tried it won't boot that way. I was assuming that it might go both ways, bc i know when the phone is on you can pull the batt and as long as its plugged it it stays on.

Did you get this to work?
Based on your post count, this is probably a stupid question but:
You tried charging in an outlet (not through computer), right? Any under-the-hood work makes my Bionic run hot and burn through the battery.
More technical: I read somewhere that someone upgraded to windows 8 and fastboot stopped working. Windows 7 fixed the problem (if you're saying that fastboot is the problem, not Vol - & power button recovery mode).
Were you in the process of rooting?

I am kind of having the same problem. I recenty got a droid bionic where I had to replace the LCD screen and battery since when I got it it did not have a battery with it. I got an NON-OEM extended battery and every thing was working fine for three days. In that time I was able to upgrade everyting to the latest software, fireware, and Android version (4.1.2 JB) but after those three days the phoe woould not power on. When I plugged it into my computer and tried, the white power light would just blink at me. when I unplugged it from the computer and tried it would not even come on. I thought it was the battery so I sent it back and got an OEM extended batter and a OEM dock/charger. When I got everything I plugged it all in and the screen came on with the Motorola M logo and then showed me a picture of the battery at 5%, so I let it charger over night. In the morning I pressed the power button while still plugged into the charger, the phone light up saying the battery was at 100%. So I took it off the charger and tried to power up. Nothing happened. I plugged it into my computer and the white power light came on and stayed solid but still no power-up. I just tries the Volume Up/Down power while plugged into the wall charger and I can get to the recovery screen and try the normal boot up, I get the Motorola M Logo screen, I just now tried recovery and the little Droid just showed up with its stomach with a red triangle and an ! in it and is just sittin there. and now it when back to the Motorola M Logo screen then the battery screen. Does this mean mine is bricked as well? Please some one help.

Bumping because of no help yet. I can access the recovery screen but does not seem to help any, it also has to be plugged into the wall charger for this to happen but I can not power it up whether it is plugged in or not. Please Help someone so I can get this figures out.

Alright strange thing to try, plug it into your computer, while plugged in take it the battery, give it a minute and put it back in while still plugged in.

Did as you suggest but when I took out the battery. the white light stayed on. Still could do nothing. Waited 2 minutes, put the battery back in and still nothing. All I get is the white light staying on. I unplug from the computer, the light turns off and still nothing, not even the recovery screen will boot up.

Can you get to the fast boot option by holding both volume buttons and power

As long as I keep it plugged into the wall charger I can. When I go there it says "Battery Low Cannot Program Connect USB Data Cable. But as soon as I unplug the wall charger it shuts off and I can not get back to fast boot. When I plug it into the USB cable and plug into the computer, I can not get to fast boot. I just check and it says my battery is at 100%. but when I first plug it in it says 5%.

Your gonna need to charge your battery with either an external charger or the usb charging hack before you can perform an fxz on it

[Q] HTC One Will Not Charge

My HTC One had a full discharge a couple days ago.When I got home to plug it in, it showed a blinking red LED and the battery charging animation, but didn't charge at all over a full day. I tried rebooting while still plugged in to the wall charger, which took me to the OS. From the OS I could do anything -- text,call, use Chrome, etc -- but the battery symbol had an exclamation point and the LED was still blinking red. As soon as I took it off the charger, it turned off.
I have tried Power + Volume Down, Power + Volume Up + Volume Down, and the bright light methods.
I was able to restore the phone to a previous backup from TWRP while plugged in, but the problem continues.
Any suggestions?

Try connecting the phone to your computer's USB port. If it charges there, then your charger is bad. You can check to see if is charging by going to Settings -> Power on the phone. If you are using the cable from your charger to connect to the computer and it isn't charging then try another cable. It that works, it may just be the cable that is bad and the rest of the charger is OK.

I have tried multiple cables, including the HTC stock cable and charger. When I plugged the phone into my computer, it did not show the blinking red LED and did not power up. The phone was basically unresponsive. I assume this is from lower amperage from the laptop's USB ports, but could be wrong. The laptop was also plugged into its charger at the time.

The battery is severely discharged. Since, it will not charge via the charger or the computer it looks to be a phone hardware issue. You probably need to take it back to your dealer for servicing. Before you do that, give the connection to the laptop one more go except leave it on the for about an hour or two undisturbed. When batteries are severely discharged, it takes a while for it to recharge enough to give any indication of life.

I ended up sending the phone to HTC. I had modified the kernel and OS, but figured it was worth a shot since the phone was dead and it was still under warranty.
They told me it was out of warranty due to liquid damage. I have no idea how it may have been liquid damaged, but oh well. I wasn't going to pay the $200 to replace the motherboard so I asked them to send the phone back to me.
I received the phone last week and plugged it in. I wanted to make sure I could repeat the symptoms and that HTC hadn't further messed up the phone before I took it to a local repair shop. But what happened when I plugged it in? It came to life and began charging as normal. Either a generous HTC tech fixed my phone for free or the phone needed some interior jostling to get circuits back to normal.
Whatever the situation, my phone has been good as new with all the data just as I left it. For a full week, I've had no problems charging.
