my xperia t dead need help!T_T

hi! i've bought my xperia t today
it goes well! i've connect it to my pc, and pc companion find an update and ask me if i want to update my phone
i said yes, and it tried to install the upgrade, but about the 75% it gives me an error
and from this moment the screen of my phone turns on and off every 5seconds
with a black screen with the white sony's logo and the pc doesn't recognize him and no led turns on
after about 2hours the phone turns totaly off
i've tried to turn on with the power button and the volume down hold
and the red led flashes for 3 times
if i hold down the buttons while connecting to the usb or to the charger,
the red light stays on and after about 15min it turns in to green and a black screen with sony's logo appears for about 20 minutes
but no leds are on and if i plug it to the pc or to the charger nothing happens
sometimes if i hold down the 2 buttons when i plug it to the pc the led turns on green and the SUS recognize it
and tries to upgrade system but after a few minutes the phone seems to turn off and the upgrade fails
what i have to do? probably the phone needs to be charged before being upgraded
but if i plug it (at the pc or even at the charger) with the 2 buttons holded down the red led turns on but after 15min it turns green and the sony screen appears and freeze
if i plug it without holding down the buttons no leds turns on and i'm not sure if it's really charging or not...
any sugestion? thanks

1. Have you rooted?
1a. Have you unlocked bootlaoder.
1b. What ROM where you on before the problem started?
2. What was the last thing you did to the phone before the problem started?

But why did you try to upgrade a phone out of the box?
Oh well... My suggestion is to take it back to the shop. Tell them you bought it, connected to PC, followed the prompts to install PCCompanion and then it faulted.
Soon, we will get stock .ftf's posted here that you will be able to flash in flashtool, but that sounds like a bad phone. If the fault was staright from the box, take it back.

OK, but if there is a problem with the phone, no amount of flashing will repair a bad board or a bad chip....
I will post a stock vodafone UK .ftf here this weekend, then you should be able to flash that (Using flashtool, first post in the dev section) to repair your phone. But i do advise that if your phone id faulty from the box, its a hardware issue not software..

You need to turn on usb debugging. It's under settings/developer options. Should work after that. Good luck!

obviusly i can't turn in debug mode as the phone don't turns on!
after a night plugged to the charger (no leds on)
today the phone don't do nothing...
no flashing red led when i press any button or any sequence
only turn the red led when i hold down the 2 buttons and plug the usb or the charger
but when i release them all turns off....

Have you tried a factory reset? You should be able to do it via Android stock recovery and that might rollback the corrupt upgrade.
Worth a try.

first i need to discover what you're talking about...

Then attache the usb cable to phone WHILST pressing the volume up button on the handset (If that doesnt work try the volume down button)

[Q] Xperia T will not go past Sony logo

Hi, I have tried to use flashtools and I've got all the necessary drivers (I think) but once I put hold power button and vol+ (3 vibrations), then press vol-, connect to pc via USB and I get a temporary green led, which goes after about 5 seconds, and then my phone disconnects from my computer again and i get a constant red led while the Sony logo appears. I really need my phone to work Could someone out there please help with this! I would really appreciate if someone responded very soon as I would like to get this sorted as soon as possible. Flashtools gives me these messages:
22/012/2013 23:12:07 - INFO - Device disconnected
22/029/2013 23:29:07 - INFO - Device connected in flash mode
22/029/2013 23:29:18 - INFO - Device disconnected
Also one more thing I'd like to add.. Once I go into that BLU thing, it keeps on asking me what device I have, so I select Xperia T and then it gives the following messages:
22/052/2013 22:52:26 - INFO - Your phone bootloader cannot be officially unlocked
22/052/2013 22:52:26 - INFO - You can now unplug and restart your phone
Might this have something to do with it? Any suggestions would be grateful! I've been at this for hours now and need to get this sorted
Thanks to any kind person who helps fix this!

1) Dial *#*#7378423#*#* and goto software info/configuaration. If it says bootloader unlocked allowed: no, then you CANNOT unlock it via ANY means
2) If it says yes (I doubt it, because flashtool has already checked this) then you can.
3) Flashmode has nothing to do with bootloader. Press volume up to get into fastboot (Blue LED) for working with bootloader, press volume down (Green LED) to work in flashmode, which is for flashing FTF's.
4) If you are trying to flash a FTF, then do not connect the phone until it asks
5)Make sure you have gone to C:\flashtool\drivers and run drivers.exe. Ensure you choose fastboot, flashmode and TX drivers.
6) Make sure you are on the latest version of flashtool 0.9.13.1
Can I ask what you are actually trying to do?

Also flashmode and fastboot and adb dont work on windows 8(.1)

Its not even booting, past the Sony logo so i cannot do anything (i can't do step 1 as you've asked). Its literally a bootloop. Can you give me step-by-step instructions to get out of this bootloop? I tried to install custom ROM but it died on me, and now its on the bootloop, which i can't get passed.

Oh okay. I'm using windows 8.1, so what would I do to fix the issue?
I have given my phone to the manufacturers to try and sort out but I have a feeling they will refuse to fix it, so any help would be appreciated. If i use a windows 7 machine, would it work? If so, how do I fix it such that it exits bootloop and allows me to access my phone. I don't mind losing all my data (although i think its lost anyway lol)
P.S. thanks for the reply.

I'm sure your batt is dead. Try the rubber band method. Give it like 2/3 rounds of it on the power button and hold it and plug in charger. it should charge with red led on. Pull battery and try again if it does not charge. Give it some charging and it should be able to enter flashmode to flash stock.

I don't think the battery is dead, as the led would just blink and wouldn't even show me the Sony logo.. Everytime i use the phone with the charger it goes into the bootloop, looping around the Sony logo and then switching off again, then the sony logo will show again, etc. I've sent it off to Sony manufaturers. Would they fix it (even if the manufacturers warranty is void)? Like, even if they charge a little (hopefully not stupid amounts of money lol)? If not, i'm going to try and use flashtool on windows 7 machine and hope that it works, as I've heard flashmode and fastboot and adb do not work on windows 8(.1), which is what im currently using :crying:

Press power button and vol up key together until it vibrates. Phone should start up?

Yes (or, at least its definitely one of the reasons). Use Win 8 or Win 7 or Win XP.
If after that point you still have trouble with it sticking to flashmode: I also had trouble flashing via flashmode with one of my USB ports. I like to use the front ones on my PC but they don't work for every device. There is also a USB cable that I have that does not work for flashmode. Consider these 2 things

I'll try windows 7 when I get it back. And wow really? I didn't realise that using different cables actually made a difference? At the end of the day, if it charges the phone it should work! Lol, Sony know how to make things real complicated!

Experia T stuck on SONY logo
Help, another help
I read about the leaked 4.3 and the latest 4.4
Did much flashing with HTC Desire.
Now I made a big mistake trying something with my Xperia T
Using DooMLorD flashtool I got into fastboot mode and then clicked on 'Reboot device into system'
I WISH I HADN'T
Now my Xperia T is dead.
Starting up it gets stuck on the SONY logo, nothing, nothing happens.
Please help me recover the device!

It's just a soft brick. What did you wanted to flash? Just flash a stock .ftf file with flashtool, or a kernel with recovery.

Well, first of all I want the phone to start up normally again so that I can use it.
What I did achieve up till now is that I can get it connected to flashtool in Fastboot mode.
I guess this gives me the opportunity to flash a boot.img first so that I can install 4.4 or 4.3 later.
But first things first.
Do you think flashing a boot.img could restore the phone in a state that it functions as a normal phone again?

My xperia t has gone in for repair. Before considering this though, could you try one thing to see if it'll help restore phone? Go to your PC companion (and no, its not a standard recovery which i'm going to suggest so keep reading!). Once you have done this, click on "Support zone". Click "Start" on the "Phone/tablet software update" option. Note, you do not need to plug in your device yet!. You should get an error message coming up saying device not connected. And once you get this, there should be a message asking you whether you are having "severe problems with your phone/tablet". There's a "repair my phone/tablet" hyperlink. I want you to click that and NOT the connect button. Once you have clicked that, please follow the on screen instructions. Tell me if this works for you I hope it does!

Why?
Because SONY decided that I have made changes to my phone and SONY now refuses to repair my device.

Ah that sucks! Are you not on windows 8? I've heard that windows 8 and flashtools don't get along, but if you're saying you've got your device into fastboot you should be able to flash it using flashtools!

Sony Xperia T LT30p dead resolved
OK, here it is for those interested on how to revive a dead Xperia device.
Yesterday my phone stalled at the SONY logo.
Nothing could be done anymore.
My phone has returned into normal state thanks to SonyXperiakiasT :good:
Follow this thread: http://forum.xda-developers.com/showthread.php?t=2315572
Howto get into a state that one can flash the phone.
- download: LT30P_9.1.A.1.141_PL.ftf (the original firmware)
- install and activate flashtool-0.9.13.0-windows.exe
- at the SONY logo push on/off, vol-up and vol-down together
- when the phone vibrates an the logo disappears release all buttons and immediately after push on/off and vol-up button
- when phone vibrates release on/off button, keep pushing vol-up button and plug in USB cable from computer
- you will be in a state with a blue light at the top left of your phone.
- however you want to get in a state with a green led
- push vol-down and on/off
- unplug the USB
- wait for the phone to vibrate
- release the on/off button and plug in the USB
- Follow the instructions in the thread mentioned above and your phone will be revived.
All the pushing, releasing, plugging and unplugging is a quite delicate affair.
I tried it during several hours before I got a bit of grip on it and still I am not shure how I got into the green led state.
Try it, be patient and be shure that repair is within reach as soon as you have a green LED on your phone.
Good luck!

Hey so I ran into this same problem! my phone wouldn't do anything except boot up to the Sony screen, no lights no charging nothing
I figured it out, at least for me
>Have your flash ready to go via Flashtool
>Have your phone plugged into your computer via USB
>Hold the volume down button and then while holding it turn it on
you should have your green light and may have to hold the volume button the whole time until its done flashing.
Hope this works

FIX!
Hey the same thing happened to my xp T few days ago. My phone was rooted with UB. I was stuck on SONY LOGO too n my phone was rebooting from there repeatedly but I was managed to get into cwm n I installeddifferent kernels + Rome but it was no good. Like u said in your OP I couldn't get into flashmood too. When I select the firmware flashtools say preparing files then the phone reboots! Then flashtools say device disconnected!! The solution for this is when flashtools says device disconnected pull the usb cable n press vol up with power button n turn off phone. Then once turned off straight away press vol down n plug in usb cable n flashtools will start flashing. The important thing here is not to close the window that pops up when flashtool say device disconnected in red. Hope this helps, same prob worked for me so should work for you! Peace

Sony Z3+ E6553 Dead After Flashing with FlashTool

Are you sure that your battery is charged?
Try this: press and hold power and volume up button for 10 seconds and see does the phone vibrate.If vibrate flash again via flashtool.,he should works.

Battery was fully charged and I've tried that but phone does not response at all to flashtool. When plug in to PC, in device manager under USB controllers, it sees it as SOMC Flash Drive. I think the phone boot is dead.

Now when I tried to flash it again, volume down, insert USB the flashtool show as: Device detected with USB debugging off. It doesn't go to flash mode anymore. I took the back cover off, remove battery connector flex cable and connect it back and try flashing many times but flashtool will not detect phone in flash mode..PC can detect phone because it makes connecting sound on PC but detects as what mode I don't know. In device manager, it doesn't show any device in com port but it shows SOMC Flash Device in USB controllers. I tried to press volume up + power but nothing happened. Once again thanks for your help.

[Help] Bricked Lumia 1020 - Blank Screen - USB Undetected

My 1020 got bricked while flashing through WPInternals.
In the middle of the flashing the USB got disconnected and after that I have blank screen. The power button pressing does make phone vibrate. Also soft reset combination makes vibration. However I am not getting anything on my laptop on USB connection. No connection notification. Nothing on device manager. I tried combinations to get it detected but nothing works.
So the question is, Is there any way I can blindly send force flashing to one of the USB port and make it happen ?
JTAG is the only option ?

same me hichic

Flash Mode
Hello,
try this: power off/reset and power on holding vol-up key. You should get a flash-and-cogwheel sign on your display. If so, you cna reflash your (valid) .ffu file using PhoneImageDesigner/Lumia Flash Tools (->google!).
Are you sure your USB cable or port is not broken?
Best whishes,
Joachim

Okay, I have already tried that, since the USB got disconnected during boot loader flash, it does not display anything on the screen when I start with power button or reset combo. It only vibrates.

I have changed the cable too(USB flex cable of my lumia and USB cable too), It does charge battery, does keep flashing the start button once in a while when the cable is connected. I am sure USB is working fine. But not getting detected in PC.

Not that I'm aware of sorry ... You are connecting cable to a powered on PC or laptop? Holding down both volume up and volume down whilst connecting cable ?

Also they need to hold the power button

On the newer samsung phones you need to power off your phone hold down volume up and volume down and insert your charging cable in your phone make sure the cable is inserted in a pc or a charger.
