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:

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.

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.
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?
Guys, i think my xperia is broken
last night my battery was empty so no big deal i thought.
today i've connected it to the charger to charge and pressed the ON button.
when i pressed it, a red light under the ON button started burning.
i thought? wtf? mayby because it's emty or something.
but after more then 1 hour of charging it still doesn't do anything.. and now even the redlight doesn't show up!
does anyone know what to do?

Hello dear friend, I sympathise with you I had this exact same problem and was worried sick for a day and a half that it was dead! the red light under the power button is the battery fail light (as far as i can tell) it goes on for example when you plug the charger in and remove the battery. I've found if you run the battery down to absolute minimum it almost seems like the X1 cant detect the battery any more and displays the red light. I fixed mine by removing and replacing the battery a few times and plugging it into the wall charger for a few hours. keep trying and dont lose heart, like I say it took me a day and a half (with a sleepless night inbetween
Also mine, but after five minutes it's wake up.
Try simply to remove battery, or performe a soft reset via hardware button with the stylus.
Let you X1 charge for an hour or 2 and it will start up again, guess this is when the phone don't get a enough power to start up.
(Guess it can indicate some other error as well but probably just lack of juice in the battery .. )
thanks guys..
it is still not working but i know that the phone it self is OK.
i wend back to the store and they switched the battery from another xperia.
it worked fine
i'm so happy right now. it's charging at the moment, but still not going on, well, i have to wait and see then.
again: thanks for the posts guys
Mind you... it might take a while! I had it connected to a cheap usb charger for a night (which wasn't good enough obviously) and it took me the better part of a morning to get it to life again with the SE charger. I find it most irritating that this sort of thing isn' t mentioned in the manual. At least not where I could find it. Things like a phone that doesn't want to start make you sweat horribly.
I have this problem with mine but still no luck
Been dead for weeks now.... Finding it hard to get a copy of the receipt too bah
Only had it a month too..
It's prolly one cell in the battery that are "broken".
Had that on my X1. There are 3 cells in the battery and if one of them doesn't work as it should, the battery only delivers 3-3.1 volt.
Your phone "wakes up" at 3.335 volt but dies at 3.1. I've been measure it myself.
My phone are now back in business with a new battery, a new batterycover and latest software. No problem if you have guarantee...
PS... Try to avoid one thing. Avoid heat in battery. Lithium hates heat.

You are right, man.
Usually, if you discharge a battery till the very last drop, it can happen that:
A) one of the cell goes beyond its safety level, and it "breaks". That's unrecoverable, AFAIK.
B) the cells gets unbalanced, and you nedd several charge/discharge cycles to get them balanced and fully recovered.
Add to this that Usb charging is usually unable to wake up an almost totally drained battery. This won't happen with a normal charger, but Usb charging voltage is lower than normal (of course, it's usb not home plug!) so it has not enough power to wake up the dead battery. If you leave your device in charge for some minutes, it will eventually manage to wake the battery.
However, I noticed that the X1 has a bad power management. Usually my X1 low level battery threshold varies between 10% and 5%. One week ago, at 10% it just shut down and won't recharge, showing me the red light over power button. Removed battery 3/4 times and charged with home charger, it gets recovered. Try to plug the charger, remove the battery and insert it again, doing all this with the charger always plugged.
In my opinion, that's really annoying, I never know when it *really* has a low battery!

yeah.. i had that with my P990i (symbian uiq3) phone the batter went in 1 day to 50% now it still has 80%
this same thing happend to me last night, i just pluged it to a wall charger & waited for an hour good thing when i pressed the power button it came back to life. was worried then and now its all good.
i had this on my xperia a while ago i think its just the battery is extremely dead.
after an hour of being plugged it in it turned on again
Red Power button Led
Glad to find this info, the red light gave me the chills at first too. My phone blacked out while using TomTom 7.4 on a stock unbranded NL Rom, after it had given me low batt. warnings. Now it's in the 'home plug' charger, sipping juice on the red light... I hope it comes out of it soon. Anyway, I was wondering if anybody has ideas on checking battery cell failure? Or battery diagnostics of some sort? It would be a shame to use a crippled battery just because you don't know it's operating below its max capacity. By the way, I'm not part of the lucky bunch in possession of a multi meter...
EDIT:
As soon as I hit 'post' the notification Led's display charging! And the red light's off of course. Guess the first post brings some beginners luck, hehe. Anyway, thoughts regarding battery diagnostics etc are still welcome!
Encountered this and according to the helpdesk, it's cos the backup battery is empty so he advised me to charge the phone for half an hour without the battery, and then charge it with the battery after that. Didn't work. Called up the helpdesk again and he said for some, they've to charge (without the battery) for an hour. Ok, tried that. But still doesn't seem to be working. Gonna just leave it charging (with the battery) for a few more hours. If still can't guess I gotta bring it down to the service centre.
there is a backup battery in xperia???

Remove your battery, wait 3 minutes, insert again the battery. If you have lost date & time info, no, there is no backup battery, otherwise yes, there is.
Well, anyway, sent my X1 for servicing. Over at the service centre, they tried to 'boost my battery' but couldn't get it working. So had to leave it there for them to work on it.
Just had this same problem, cleaned the battery terminals and hey presto...it's all good again..
Regards,
Astoroth
Sent my X1 to the service centre with regards to this issue and they replaced the motherboard. They'd tried boosting the battery but no use.
Same problem.. this is what happened
ok, I came back from work an as usually i plug the charger in my xperia, the baterry left was like 30%, ok, then, I connect in the 3.5mm an autput for a big Radio so i can listen full music... so.. in a while, in my house there was a power down.. really fast one... like... 0.01secs... (like down and up really fast).. in that change my cellphone went down =S.. and sice today never get up ='(... there's just that red light in the power button each time I plug the charger on... any help?.. is the same problem of the topic? :S.. plzzz.. i dont have even a month with this pretty cellphone =( poor baby
Shortly: I flashed a new rom (not so new... Mameli 2.0 with WM6.1) and the upgrade process stuck on 99%, computer saying "All Done"
No so... trying to reboot the Wizard gets up the bootloader screen... no problem, will you say BUT... I was in a hurry so I leave the USB cable connected and go away for a few hours (I suppose the USB cable may keep powered the device but now I guess no... )
So, when I came back, the Wizard was turned off.
First try was soft resetting the device with no success: screen remains black.
Then I try to connect the power supply and nothing happened...
Then I pull off the battery and keep it off for a few seconds... I was googling with the device in this state when the bootloader screen pops up for not more then 15 seconds then blank again...
No way to enter bootloader mode or to hard reset the device...
I suppose the battery goes almost flat... and I've not a cradle... is there any way to charge the battery? or a way to build up a cradle-substitute?
May be the issue due to battery flat?
Thanks, Pino
Try plugging in to the original charger, not a USB cable, with the power off.
After about a minute you should see the orange LED turn on.
At least that has worked for me when my battery has been dead.
Nothing... It was already done... I suppose the charging doesn't happen if the OS didn't load... even if I read about some stating that if the charger supplies 1.0A the charge happens...
Now I'm trying to charge the battery with "alternatives" methods...
Thank you for your interest
and so?!?!?
So much lurking... noone writing?
Ideas welcome....
I've done something similar to this too, i.e., where battery gets so low that phone cannot start charging cycle.
Here is what I have done. Take note on the battery of the positive and negative terminals (clearly marked on battery). Use a regular 9V battery and some wire (or 9V connector) and connect the 9V to the phone battery (+ to + and - to -). Allow the phone battery to recharge some from the 9V. I suggest connecting for about 1 minute or so and then disconnecting again for 1 minute or so, and repeat this cycle a dozen times or (or more) using this 50% duty cycle charging. (not sure about charging current, nor heating of battery and don't want to overheat or damage the phone battery).
After giving the phone battery some (re)charging, then try plugging phone in to see if charging cycle comes on. (try first without trying to turn on the phone. If no response then try turning phone on while plugged in to USB). Generally makes no difference whether using USB plugged into computer, original charger or after market, ... phone does not, nor cannot discriminate between different 5V 'USB' sources.
If this doesn't work then the next step is to carefully touch the 9 V to the battery while in the phone and connected to USB (and to play this safe use charger, and not computer USB ... don't want to risk damage to computer). I would only try this if you feel extremely comfortable with electronics and voltages (albeit this is very low voltage) and as a last resort. KEEP IN MIND YOU WILL BE DOING THIS AT YOUR OWN RISK, and I don't want to be blamed for anything that may go wrong with the phone or otherwise by you trying this. This has worked for me on several occassions, but I am an engineer who has experimented with electronic ciruits off and on for 16 + years and so feel comfortable doing stuff like this. (again remember + to + and - to -, battery to battery).
Good Luck
First of all... Thanks for replying...
The problem isn't due to battery too much empty (it's a frequent issue, with mobile phones too...)
I suppose the Wizard needs be correctly initialized to start charging the battery and mine was in bootloader mode.
Sometimes I am able to power up the system for a little while and the bootloader screen appears but the battery doesn't charges so I cannot disconnect the power supply... this is why I suppose I'd get better times if I got a cradle.
Now I'm trying to arrange a flying connection between the battery and my kaiser's desktop charger to give the battery a bit of charge and verify my ipotesys (uh-oh... it's correctly spelled? sorry for my bad english....)
OK, wish me luck
stay tuned...
OK, no more bricked
The issue, as I supposed, was due to a flat battery!!!
I tried unsuccessfully to charge it back using the external charger for my Kaiser, probably the unsuccess was due to difficult to obtain a stable contact between charger pins and battery leads...
After that I remembered I had another battery. It wasn't used for a bit of months (I use the wizard just as backup, when the Kaiser is out of order) but luckily I stored it full charged so the battery was able to make my wizard power up (strange thing, I needed to keep the power button pressed as the device powers down as soon as I release the button!!!)
I tried to update the rom again but it failed at 99% so now I reverted to an old rom but the device is still alive...
Maybe I'll try again the update but not before having fully charged both batteries
See You and thanks to everyone tried to help...

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.

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.
