Hi all!
I have problem, my phone battery is empty. I wan't to charge my phone, but when I'm plug in it is Connect in flash mode. Please help
Not sure exactly what your problem is, apart from flat battery, are you saying it goes into flash recovery mode when you plug in your charger??
If you have a Pro recommend taking battery out for a bit allways worth a try, otherwise the good question is does it do it power on normally with battery as sounds like somthing has damaged or stuck your back button. think it will still slowly charge in flash mode otherwise where you doing any rom kernal change when this happened?
Yes, When I'm just pluging with out pushing back button, it is pluging in flash mode. I tried to remove battery plugin the cable and than get it back, but it still pluging in flash mode
EDIT: No recovery, flash mode (when im flashing kernel or back to stock)
Your battery may have become discharged beyond the safe limit and so refuse to charge, does the LED flash 'red' or 'green' when you plug it in?
If it flashes 'green' then it is attempting to enter flash mode. If it flashed 'red' then you may need a new battery.
You cannot charge a lipoly battery that has been discharged beyond the safe limit as they have a tendancy to explode violently. Most batteries have a chip that disables charging once this has occured.
You can get new batteries quite cheaply, dont fall for the high-capacity 2000mAh lies.. Most are just 950mAh batteries repackaged in gold foil to look more impressive.

So, got a phone from a friend, X10 - not rooted, which does not work at all.
Whenever I want to turn it on, LED just blinks 3 times, that's all I "got"
I have tried removing battery, SDCard and SIM Card but still no go!
Any idea or help would be much appreciated
try this
use the flash tool and reflash a 2.1 sony rom you can easily get your phone to dev mode even with out having to turn it on

you must get back on track after that!
Ok, will try it
Not working, Downloaded Flash Tool and 2.1 *.ftf image, when I press flash and select image, I press on back button and connect X10, but no go, Flash toll says: 9/044/2011 17:44:23 - INFO - Searching Xperia....
19/044/2011 17:44:23 - ERROR - Please plug you device in flash mode
And X10 only gives impulsing red LED light!
Try with SEUS, wich will install the flash drivers for X10 in your PC, I assume you're using Windows.
Or look for these drivers, can't give you the link right now, some research will help.
I installed PcCompanion before Flash Toll, will try with this software, but I am sure it will be same...will see soon!
bah....same
a few months back ago i remember someone solving this problem... try searching the forums
NVM. Found it, there you go http://forum.xda-developers.com/showthread.php?t=944322&highlight=red+led+death
Nice one, will try it later today!
Does not help, after I connect it to charger (with removed battery) there is green light, but after I add battery after one/two mins led turns off, and whatever I press Xperia does not respond!
I tried than removing it from charger and turning on, but same, no response, after I remove and add battery, if I try to turn it on Red LED of death is still here.....
...nosi u servis..nema druge ))
If u can mesure the battery voltage, and if is below 3V it seems the battery will not receive any more current and the phone need more power to bootup than charger can provide, or phone detect the low level and don't start. This is a theory. If it's above 3.7V the problem is from other part.

the ultima looks like k800i with full touch scree. i like it!!!
hey Benko, if ya dont want it, ill take it off your hands, ill even pay shipping!
had to ask
I tested my theory about battery level and seems to be right at first look. I put a DC power supply instead of the battery an if i put about 3.2 V and below then i connect the usb cable to PC the phone don't start only flash a red led and start pumping about 3.6V for charging the li--poly battery. so the problem seems to be the battery. The problem with li-poly battery is if them drop voltage below 3.4 V is very hard to charge them back.

Now what u have is to try to put about 4V on the phone terminals an to see if it starts.
go to ebay and buy a new battery
The evidence points to a bad battery. Head to your local wireless store and ask them for a compatible battery to test it out.
Charge the battery with a 5VDC power source, take one usb cable and cut it to get the wires, then use the computer or the original charger to force some juice into the battery.

Possible solution!!!

Well, i may be wrong, but as i have been able and still use batteries that already have completed 10 years i can tell that (not confirmed) this battery starts at 3.2v and is fully charged near 4v.
I just checked my battery is charged at 90% and measuring it i got 3,93v
The best way to know for sure if it is the battery or not is to get a source with at least 500ma to supply a recharge directly to your battery, if it starts getting hot above like 40ºc you should disconnect wait to cool and reconnect until gets near at least 3,9v.
To make sure the battery is charging try to measure the amount of current ma it is charging at.
If the battery is nearly dead or dead it will still charge but in speeds like less then 10ma above this it will be charging but will take a day maybe, but you must take care on this, the current will grow as the battery gets charged exponentially.
Once charged at near 3,9v input the battery without closing the back cover and check if it works.
Wait it to cool**** you need to wait really at least a bit so you can notice if it is getting hot again on next step.
Once the phone turns on, check if the battery is getting hot again even a bit.
The battery can't get to hot only by turning the phone on, if this happens your phone can have one of two problems:
Phone has a short, sorry, damm.
Phone has a software(rom) that is draining the power.
Using external power to connect to the phone while it is connect to usb or power source can break your phone, don't do that never.
Charging voltage must be at start near 4v to 4,5v, if it gets to charge to fast keep an eye on it to not get too hot, it can even blow if passes beyond 70ºc (i melt plastic once doing this, rsrs)
I hope this works, took me awhile to check the correct voltage for this, rsrsrsrs
hello,
i have a bit of a predicament here. yesterday, i was preparing to pack up my atrix as i am selling it. i was making use of fastboot - erasing system, user data, recovery, and so on. the long and short of it is this: i erased the custom rom on the atrix, and i also erased the custom recovery. i didn't realise the battery was low, and, well, it 'died'. when i plug the phone into a charger, it doesn't go past the red motorola logo, the green led doesn't turn on, and the phone doesn't appear to charge.
i cannot make use of fastboot to flash a recovery image, as the battery is always too low to flash. whenever i try and charge the phone, it doesn't get past the red motorola logo (as the phone has no rom installed, and the custom recovery image has been erased), and the green led doesn't come on, as stated above. if i unplug the phone from the charger - be it after an hour, or two hours, it turns itself off immediately. trying to charge the phone via usb yields the same result.
so, with that said, it looks like i will have to buy a new battery, as that will have a bit of charge in it, i imagine. i imagine te original recovery is long gone, and there is no other option but to buy a new battery?
Well, you could charge your battery on a friend's phone or a store, or ask a friend to lend you their battery.
Once you get a battery with a charge, fastboot a recovery, copy a rom zip and flash it
There are more threads about battery charging than I have fingers, (and yes I have all 8 fingers and 2 thumbs)! I am not going to search for you for this exact reason. The predicament you are in is very easy to get out of! Use the search function, that's what it's there for!

Agree his method.
Simple method. Take an old phone charger or USB lead. Cut of the micro USB end. Strip the red and black wires. Fasten red to the positive terminal and black to the negative terminal on your battery with some tape. Let it charge for a few hours. Unplug if battery gets warm. This should put enough charge into the battery so you can put it back in the phone and flash. I had to do this with my HD2

Or try this just to see... it helps with some battery problems. Take the battery out and plug in the charger. If it goes to a picture of a battery with a question mark... put the battery in and let it charge.
Hi,
Few days ago I forgot to reload the battery. Now that I try to bootup the gt-9100 it only shows battery logo with loading sign. It won't react to any button presses, so i can't get to download mode or to recovery mode.
I flashed CyanogenMod 9 Nightly a week ago. It worked like charm until now.
Does some one here have any kind of suggestions I could try?
Thanks..
How can you be sure that the battery has enough energy to boot the phone as you can still see that it is charging? Eventually the battery should be reported as fully charged.
when it depleted i connected it to charger and left it there to a whole night.
it should have enough charge.
just tested some some key combinations and i got good results. when i push vol down + home + power before i put battery back to the phone, i get to the odin mode.
now i have to find usb cable somewhere.
I got it flash new rom to it. First time the problem still persisted.
After trying some new button combinations and after flashing cmw i got it boot up.
Few seconds after fully booted, it powered off and i got same battery logo that does nothing. I'm starting to wonder that the problem is somewhere in the battery or the battery charger system.
Yes, might be a problem of the battery or the charger. If possible you should first try this battery in another phone and/or another battery in your phone.
If you have the possibility to charge the battery outside the phone that too would we worth to try.
For me it looks like your battery is empty but I might be wrong.
Flashed it again with a samsung stock rom. Now its staying alive.
Now it notifies me every few minutes that "Charging paused. Voltage too high.".
The phone is not currently connected to charger.
My guess is that the battery has gone bad. Unfortunately i don't have any other batteries or phones that i could test.
I think i have to go and buy a new battery.

Actually, this sounds like the port may be bad. You could try cleaning it... But you'll probably have to replace it.
I think I have screwed up badly....
I was using MattyP's 215 leak to go back to 211... while it was downloading/flashing system it somehow hung up. Now it will only boot to the AP Fastboot mode and the battery is low - low enough that the moto flash command(s) will not work (says battery is too low).
I've tried a bunch of suggestions found here to try to get the battery charged, and none of them work. I know that if I could just get a 50-70% battery charge I could redo the flash and get the phone to boot.
So, any ideas now on what to do? The only other thing I can think of trying is the suggestion from another post to cut open an old USB cord and connect the black and red wires to the battery posts to get the phone to 'think' it is connected to a full battery. I'm just afraid I will fry the phone....
Any suggestions? Unfortunately I am out of warranty (just this month, naturally - Murphy's law!)

There is a factory cable that let you power-up your device without battery so you can flash it.
http://forum.xda-developers.com/showthread.php?t=2055839

- The Razr must be charge to the minimum required the bootloader to enable the flashing process. There are other ways to charge your phone without the stock charger. You can search here on XDA for it.
PS: The factory service cable, allows you to bypass the battery check, by allowing the Razr to receive 5v straight from the usb port. As per CellZealot explanation on third post.
I replaced my old Droid X a long time ago. Eventually the battery swelled and I threw it away.. so my old X currently has no battery. When I plug it into PC USB, nothing at all happens. If I plug it into wall power, the Motorola logo comes up, then a few moments later a big emtpy battery icon appears with a question mark in it. I can't get it to go anywhere from there.
Is there some kind of key combination I can push to force it to boot into the OS or is a battery, even a dead one, required to operate the device?
I just want to tinker around with it.
You are going to need some sort of battery. My X's battery lasts a grand total of 27 seconds after boot but as long as it's there I can flash roms and turn it on. I had an issue where I had to flash a rom to charge it and I couldn't flash a rom till it was charged.. I looked everywhere for a way to use it without the battery but the only one was to find a charged battery. I ended up borrowing a friends' battery.

I have booted phones into download mode whiled connect to my computer via USB. I believe it depends on the phone. My thunderbolt's battery was dead, but I was able to boot it with dead battery

interesting to know. I've tried charging my battery with a USB charger and it takes forever to get any type of charge. I am surprised to hear you could boot the phone with a USB.
What would happen if you short out the battery contacts while it's plugged in? Would that trick the phone into thinking there's a battery in place?
