[Q] Stuck in Sony Logo with no battery at all, quick help needed plz

am really sorry if this was a repeated question, but am stuck in sony logo and i cant close the phone to make it charge, battery is dead, it closes it self for 5 minutes to charge then it opens back to the sony logo and stucks there till it consumes the battery then loops.
dont know what to do, i've searched here a lot with no accurate answer
i've tried (Power+vol-up) it closes then it automatically turns itself back on
its not even recognized by the flashtool and the PC companion
any help guys will be really appreciated

please any help guys, its really heating up like crazy

I've totally lost the the battery, it loops at the sony logo then totally off in less than a minute with red lid, then back on in the sony logo with lower red lid then off then on... etc
power + vol up for more than 20 sec does nothing, no vibrations, nothing at all
power + vol down does notheing
power + vol up and down for more than 20 sec does nothing as well
flashtool and PC companion are not recognizing it, while i just used the flash tool yesterday, same latest version with the same PC
i think its dead right now
if just anyone replied by telling me how to shut it down while keeps it charging, I could have prevented it from this endless loops and saved it

thanks guys for not helping at all, i had the feeling that am in a desert talking to myself here
anyway after like 10 hours of digging and digging i managed to fix it
if anyone has the same problem please follow this awesome guide http://forum.xda-developers.com/showthread.php?t=2229250
one small comment: even the battery is dead the flashtool could detect your XZ, i think it reads the main ship with no power needed, just don't lose hope (I've tried to enter the flash mood like 20 times) and finally it worked, flashed my stock .67 tft then i got all physical indicators back (Lids, Vibrations, buttons are functioning) and it couldn't start as there were no battery at all, it gave me the battery icon and after like 5 minutes of charging it woke up

i think it wont charge as it can't reach the kernel, you have to find a dock charger then plug your device in till the green notification light is on, which means u've reached 90% of battery charge.
the dock charger is the solution for this man, the wall charger won't be able to pass the kernel to charge the battery
then please follow the guide again after your XZ is charged up

Dead xperia T

Well my GF had a lot of trouble with this phone, we replaced the battery 3 times due to them failing. Anyway I updated it to official 4.3 for her and left it totally stock, no root or anything. All was well for a few days. One night we left it charging, when we woke up it was still pretty dead. She used it for about 5 mins then it died, now it won't charge or switch on! Got it charging offline but still didn't take any juice. Flashed in flashmode several times, now if I connect to anything it goes straight into flashmode and still won't charge! I bought her a galaxy s2 for now but is there anything we can do? Is it possible it needs yet another new battery?
Just to add I tried all the fixes such as leave it on charge, remove battery, button combo etc. When it does "charge" it doesn't take any charge
Sent while my supervisor wasn't looking

Try replacing the battery again and if this happens again it is definitely a hardware problem

I don't want to start a new thread, so I will post it here. My Xperia T is a dead phone in the moment and I was searching the web and of course xda to find a fix (like for Xperia Z).
How it happened: Yesterday my phone was working like a charm with CM11. I wanted to sell it and so I was trying to flash a stock rom. The flashing aborted with error every single time (Processing system.sin). I was able to flash all the .sin except for system.sin
After the phone was a soft brick I could enter fastboot/flashmode and flash the kernel from CM11 and install it without any problems.
I tried several times to flash stock until my phone bricked. Now it is charging and nothing happens, no fastboot, no flashmode, no sign of life. Only when the battery is detached the LED flashes one time (red) when cable is connected
Edit: The phone was able to go in flashmode but after few seconds it disconnected, in reconnected in flashmode. Also the phone is now recognized by the computer as "qhsusb-dload"
Edit Update: When I connect the phone to the computer an press Vol+ and Power Button for a longer time, the LED turn on (red color) and the qhsusb-dload disappears from device manager. After 2-3 seconds the LED turns of and the device manager shows qhsusb-dload again.
Now I have connected the phone to wall charger with a rubber band on the power button and sometimes the red LED turns on and stays for a few seconds

[Q] Xperia z won't Boot but weird situation only for XPERIA GURU

Hi wonderful XDA forums, i'm an italian user, then sorry for my bad english.
I'm in a very strange situation, the new year starts strange for me.
Yesterday trying to short circuit the resistor to make the vibration works again( i read on internet and i see that works with other Xperia Z), the phone power down and won't boot anymore.
The strange things appears now, when i plug the usb cable for charge the phone, nothing appear, no LED, but if i disconnect the battery with the USB cable plugged-in the led blink red one time then blink a second time and become blue, and if i press volume down immediately afer the first led red blink, the led become green for 1 sec and the phone go in Download Mode.
When i use original Sony charger same situation, but when i disconnect the battery the led blink red 1 time and stays on and the phone shows SONY logo but immediately reboots go in a bootloop like this, red 1 time and stays on and the phone shows SONY logo but immediately reboots, i noticed that if i press power button several times after the SONY logo i can see the low battery icon but if stop to press the button the screen goes off and restart the bootloop describes upper.
I try several wall charger, and several cables oviusly the original SONY USB cable and wall charger, but nothing change, the battery is new and works because i test it with another phone.
Connecting to PC i can flash rom ftf with FlashTool without errors, but at the end of the process the phone won't boot, and won't charge same problems.
I noticed that the phone can't be recognise if the battery is connected, just when i disconnect the battery the phone go in fastboot mode or in download mode, for example when i flash a new ROM with flashtool when ask to connect the phone i must disconnect the battery and press volume down (in this way the PC recognise the phone, and the phone go in download mode) then i can connect or left disconnect the battery, anyway the flash operation would be OK but nothing change.
Sometimes when i connect the phone to PC the system ask me for QHSUBS_DLOAD drivers and sometimes the phone is recognised with SOMC FLASH....
I know this is a very bad situation, only Xperia Guru's can help me, but probably this phone is dead.
But I trust in XDA Community and i know that is the only place i can get serious and valid reply
Regards Samuel

this sounds exactly like what happened to me
This is extremely weird this happened on the same day... ?

Hi friends, welcome to soft brick world i think.. But i m happy and unhappy that i am not the only one in this weird situation..:silly:

"short circuit the resistor to make the vibration works again" thank god I didn't try it.. otherwise I'd end up with dead device

Will only boot to fastboot mode

Hi everyone. my z3 compact got wet... waterproof phone supposedly but it soon turned itself off. i've had it in rice for a while but it wont boot up. I've used the yellow reset button and it vibrates 3 times and does nothing. when I plug it into the computer tho I am able to get fastboot mode. I'd rather not have to send it back to Sony as I am without a phone. anyone have any idea how I can get it to boot normally. I'm presuming as it goes into fastboot mode the hardware isn't bricked? thanks for any advice you can give me.

Did you already tried to flash full stock TFT via FalshTool (and Phone in FlashMode)?

I'm currently waiting for a password for the flashtool..... I tried running repair phone on sony pc companion and the pc seemed happy but the phone still wont start. 3 vibrations when I try. currently the phone is plugged into the wall hoping it will charge. it is showing the red battery icon that flashes. I suppose the first hurdle is to get the thing to charge altho last night before I tried the repair phone option when plugged into charger it did say 100% charged.

Waiting for a password for the flashtool? It's free and shouldn't need any passwords, unless you mean password from Sony for unlocking your bootloader? I hope not.
Three vibrations means turning the phone off. Two vibrations is on.
Try the power button while plugged into a PC to see if any USB functions start when the phone boots up. If the phone can be seen in your PC but nothing on the phone, then the screen is duff.
I think the next stop is Sony repair centre, or if it's out of warranty, $80 on a genuine screen on ebay, a guitar pick and a hair dryer.

thanks guys. ok i've done some googling. seems I have been looking at the wrong flashtool. I was looking at one called Emma..... the official sony one. I'm now presuming I should be using the one at flashtool.net? I'll have to download that at home later. works pc has all sorts of blocking things on it. the screen was working yesterday as I could see the fastboot screen but that was all I could get. Am I right in saying the led ligghts blue when it goes into flash mode?

Good news, if the screen comes on and it goes into flashmode then it should be possible to rescue it.
I'm still puzzled as to why the partitions/system would be corrupted from water damage, unless it's something to do with the motherboard itself.

I have had the phone plugged into the original wall charger for a while now. the screen goes from blank to the battery charging icon every 3 or 4 seconds. The battery is red showing low charge and doesn't seem to be going up at all. If the water indicator shows red (which it does) will this void my warranty with Sony? I'm going to leave it on charge here all afternoon at work til I go home. That will have given it about 5 hours on charge so if the battery isn't improving by then it isn't looking good is it..... I've managed to get flashtool on the pc here and it has detected a device in fastboot mode. Don't know if this is a good sign or not as without the battery charging it's useless

Just get an full stock FW (TFT-File) and put it in the correct folder for FlashTool.
Then flash the full tft rom - HowTo here:
http://forum.xda-developers.com/xperia-z/general/tutorial-how-to-flash-stock-roms-t2240614
To get into Flashmode (not Fastboot Mode) push Vol Down (hold it) and then plug in USB (while phone is off!)
But do this first if the Flashtool program ask you to do so...

You are right to be worried about trying to flash the device with a low battery. If power fails during the flash it really will become a brick.
Don't try a flash unless you have at least 7% battery.

Thanks for all your help. Battery won't charge at all so it looks like the only option is a repair shop..... Like you say it really isn't worth risking bricking it.
