Hi XDA community, i open this thread for know if anyone have a similar issue.
When i connect the USB charger to my Xperia Z, nothing appear, no led and no vibration, seems totally dead, this occur with an original wall charger or with a PC-USB connection, but just when i disconnect the battery of the phone with the USB cable connected to USB PC or wall charger, the red led blink 2 times and become blue if i press immediatly vol+ or become green if i press immediately vol-, obviously immediately after battery disconnection.
With the battery connected no signs of life, seems that if the battery is connected the USB connection refuse to activate, but the strange thing is that without battery i'm able anyway to flash any firmware without problem, but after a correct flashing without error no signs of life and no boot.
I think there something wrong with the battery management, but the battery works 100% because i tested with other phone and work, and i tried to use other working battery but always same problem.
Anyone have this issue or know something about it?

My battery totally died last night and powered off when it ran out of battery however now I cannot charge the phone at all. It was on charge all night and no charging light comes on. Ive tried with the mains cable, usb cable to pc and in car charger.
Does anyone have any suggestions to get it working again?
Thanks
Did it just randomly die? Is there anything you did beforehand that could influence it, like dropping it (in water)?
I'm not entirely sure what it could be, but if you could provide this info, others mide have an easier time troubleshooting.

HI
greetings,
connect the phone to charger and press and hold the power button for 30 sec and see if the led is flashing
if not then connect to pc and try to boot into bootloader menu and tell what happens. weather it boots, does it just vibrates or does the led flash
Hi all, i recently was given an Xperia T by a friend who no longer uses it. Seems to have a bit of an issue that I'm hoping those with more experience in the mobile world can help with.
When i plug the phone in to charge, she flashes red led, Sony logo appears with a constant red led then the screen flashes and the phone repeats the exact same thing.
I have done the whole repair my phone through PC Companion, Built the ftf from the PC Companion and flashed using Flashtool but still no joy.
Also tried powering with the battery removed resulting in the same.
This has been tried on both the wall charger and PC Usb.
Here's the interesting part, i decided to hook the +5 and GND from a chopped usb cable directly to the battery while connected to mainboard (soldered to points on top of connector) and the phone boots to 4.3 with no problems. Obviously the battery shows 100% charge doing this and as soon as you unplug the power, phone powers down.
Any ideas as to what the problem may be. Battery seems a culprit but I'm not too sure since it doesn't fully boot with the battery disconnected.
Any help would be greatly appreciated.

need new battery.
I have an Xperia T (for fixing) and It seems not charging the battery, every time i plug it in the wall charger the red led notification show up, then blink, then shows up again. the battery is cold and it doesn't charge
the weird thing is that I unplugged the battery off of the phone, connected the phone straight to usb (without battery) and phone turned off of course. suddenly Sony logo appeared then charging icon appeared as it's charging! but there is no battery, also sometimes it shows up even when the battery plugged in but the battery doesn't charge!!
Please anyone familiar with this issue let me know, if its a Hardware or a Software related.. or something to do with the charging circuit or some components in the mainboard?
thanks for any respond!
i appreciated so much!
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
Hi. I have a Xperia Z c6603 that suddenly started to charge only when turned off. And even that, only sometimes.
If I have the phone turned on, and connect the USB cable, the phone won't detect it, so it won't charge. And won't even be detected by a PC with ADB. Also, trying to charge it by using the side golden contact won't help, neither.
If I have the phone turned off, and connect the USB cable, the phone will always detect the USB cable, the LED will go red, the screen will show the SONY logo, and then will show the battery icon with the current charge level. And then, sometimes it will start charging. But I will have to try to connect and disconnect the USB cable several times until, maybe, it would do it.
The USB port was replaced sometime ago, and it has been working with no hassle at all. I don't want to get a new battery delivered, if I'm not 100% sure that the battery is the problem.
Can be an electronic trouble with the charging circuit? Has anybody been in this very same situation?
Thanks all.
