I will describe what programs showing because i have polish version and maybe you can't understand them:
When i'm trying to connect to pc companion when pc recognise phone i'm geting message PC companion could not connect with device disconnect device and try again
When trying do sof/hard reset nothing happens
When trying to pull in fastboot or flash mode pc recognise phone always the same in conrtol panel ZEUS FLASH device pc also recognise in thisa mode without battery and without pushing any buttons but i'm not geting any led Green or blue only when i'm conecting charger or usb cable WITHOUT battery it blinks red ones
When i'm trying to flash with flashtool or original update service when program is on screen asking me to connect the device i plug usb pc recognising the phone (usb connected device sound) but program doesn't start to flash or even recognise
i have also setool when i'm trying to flash by setool when program is waiting for device connecting bar is moving on down side of window when i connect the phone it is stoping like it tries to connect but nothing happens....
i was thinking to try this but i have cheked battery voltage and it is 3,88 so i thing it is fully charged:
Here are the steps I took successfully revise my phone from soft brick.
Let the phone charge (long long time = 4+ hrs) on wall charger.
Red light on (constantly - not flashing) - charge until red light off (again very long time =16+ hrs)
Unplug from wall
Run flashtool from PC and run flash .111 until it asks to put phone in flashmode
While hold volumn down and plug in USB
Red light will be back on, after a few seconds - flash will run.
Unplug USB then power on - phone will boot and die (it's okay don't worry)
Charge the phone again - after a while (or let it charge full), you can now turn on the phone.
That is all ... Back and running.
GOOD Luck.
Timing = could be different from phone to phone - depends on battery of the phone before it dead.
please do you have any idea? for me it hangs in some kind of boot mode and i don't know how to kick it fromthis and reflash if any screens can help please tell me i will do them

I forgot to add when i'm doing test point to unlock for example ARC it is also recognised as ZEUS Flash so i thing it stays in some king of boot mode but there is no information in the net how to kick it out or even do jtag because i can doit also but i think it is not supported yet

You have an xperia T, then how can you connect the phone to the PC WITHOUT a battery? It is not removable in the Xperia T!
Have you flashed anything to the device before this happened?
EDIT
Run flashtool from PC and run flash .111 until it asks to put phone in flashmode

Which firmware is .111? I dont beleive there has ever been a .111 firmware for the T? Can you give me the post you found that in and the download link, thanks

i disassemble the back cover it's very simple the battery connector is on the flex cable i know what i'm talking if you want i can send pics i'am using flashifile LT30p_7.0.A.1.303_CH the most important think that no program is detecting the phone only pc recognising the phone

OK,
Yes thats true but it sounds similar to a problem I have come across before. But this happened when someone flashed the S1 update on the TX instead of the T.
Have you unistalled evrything android/sdk/adb related from your computer and started again.
Also, you can try another machine.
Are you on win8? That has issues with drivers from Sony.

Yes, it sounds like your friend has done something silly to the phone. Untill we know exactly what he did, and what he tried to flash we are just guessing...

I dont know where testpoint is on xperia T as we have never been down that road here.
Has he tried to use EMMA to flash something? That is meant only for unlocked bootloaders, maybe he has messed up with that, but I am onl guessing here and i cant really see why that would do anything to the boot...
Maybe he tried to flash it, dropped it, broke it, and thinks a software hack can help him....

[Q] Help. might bricked my phone.. what to do?

was flashing dogslys relock bootloader FTF with flashtool found in the Q&A here http://forum.xda-developers.com/showthread.php?t=1903137 .
flashing went fine according to flashtool.. now though, i cant turn the phone on, only slight little vibration and a flash of green notification led appears.. then nothing, when i plug it in the pc again, it is instantly staring up in flash mode, green led on. and after 30secs it turns it self off then on again, constantly connects and disconnects in flash mode..? what can i do?

Repair phone using pccompanion.
Or flash a srock ftf in flashtool that you can download from the all in one thread
These are the usual steps to take on a soft brick

how do i use the repair function in pcc? nothing happens when i plug it in, guess that have to do with flashmode?

run pccompanion without the phone attached, go through the steps to update the software and when pccomapnion asks you to attach the phone then attach it then.

[Q] Xperia T - won't go past sony start sreen

Hi all, I'm new here and very much a novice when it comes to phones, operating systems etc so excuse me for the noob question and complete lack of knowledge...
My Xperia T developed a microphone fault whereby nobody could hear me when I called them (incredibly faint). I had the phone repaired at a local repair shop. Almost immediately upon receiving the phone back it developed a (What appears to be very common) battery fault, whereby it would reach 80% then shut down, restart, shut down, restart......
So, before returning it to the shop for further repairs I attempted a repair using the sony software. Half way through this repair the phone shut down!!! PC lost communication and I was left with a phone that simply displayed the 'Sony' start-up logo.
I have now returned to the shop and they have installed a new battery but are unable to get communication with the phone via the sony software (so basically they dont appear to be getting any further than me!). They are saying it is beyond repair - but I find that hard to believe? Surely it is just a software issue?
Can anyone advise what can be done? I am reluctant to write this phone off - surely it can be flashed with a new operating system or whatever needs to be done to what is essentially now a 'dumb' device?

This is the way to fix the software issue, ALL YOU DATA WILL BE LOST. And i'm not responsible for anything might happen to you device . DO THIS AT YOUR OWN RISK.
Google xperia t .145 ftf file
Google flashtool for xperia
Download them
When you have installed flashtool, go to its folder, install drivers (tick the TX, flashmode and fastboot drivers boxs)
Open flashtool, click the lightning logo, select flashmode
Put the firmware file you've downloaded to the firmware folder in flashtool folder.
Connect the phone in flashmode, hold power and volume up until it vibrates 3 times, now hold the vol down, plug your phone in the computer with flashtool running, you will now able to flash the firmware.
Good luck man.

Thankyou very much for your reply!! Thats what I need, a step by step muppets guide!
To be honest I couldn't care less about any data, I'm way past that stage - if I can just have the phone working again I would be a very happy man (I'm fairly desperate as you can probably tell, Im running my business from an ancient, failing HTC desire following weeks of the shop having the sony!). I can't really afford to write off a phone I paid good money for 6 months back so need to have a go myself.
I am collecting the phone today so will give that a go.....

So I had a go at the above - got the flash tool installed (Emma?) etc and managed to get the software to see the phone - unfortunately though I had neglected to mention the phone is locked to a particular network, which Emma politely informs me.
So, I have attempted to follow unlocking instructions as per the sony instructions (on their website):
But I am stuck. I was getting nothing when using the volume down button and connecting. To get the computer to see the phone I have to press and hold the power button, the red led starts blinking 3 times, repeatedly. This causes windows to recognise the phone when plugged in via usb, but I was not being asked for drivers (as per sony step 13). I found the device in device manager and uninstalled drivers in an attempt to force this. Now all that happens is the device appears in the list as 'S1 Boot Load' with a yellow exclamation mark. However I have then tried installing drivers manually from the location where I copied 'android_winusb' to, but this does not work.
To compound the issue I think the battery problem is causing the phone to cycle. when connected the green led lights up for a bit, but then goes off, then back on, then red.....repeatedly. The device only appears in device manager as 'S1 boot load' when green. This gives a very short window to try to do anything.

Wrong flashtool, download the one from the Dev section and flash a stock FTF

I've been dealing with a similar problem. When connected to a wall charger is your phone cycling from Green to Red and keeps doing that? Also have you installed Sony PC Companion maybe your phone will get recognized from the drivers in that install.

Same problem
Hi, I am currently having the same problem. 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. 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.

Question is, will is definitely work if i use windows 7? I.e. is the fact that i'm using windows 8.1 the reason why it's not working?

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:

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:

Hello. Have you tried hard reset?
Press power button and vol up key together until it vibrates. Phone should start up?

Question is, will is definitely work if i use windows 7? I.e. is the fact that i'm using windows 8.1 the reason why it's not working?

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!

No it dod not.
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

USB doesn't work, port is physically OK.

As stated in title, I can't do ANYTHING using USB connection.
1. When trying to connect in fastboot mode, blue led lights up as usual but Windows says my device is broken and can't recogize it.
2. In flashmode, led lights up red and green immediately and PC also can't recogize it.
3. Doesn't charge, no reaction to charger when it's turned on.
4. When turned off and connected to charger led lights up red and green (the same as in flashmode)
Currently I'm running latest CarbonROM, no recovery nor root (can't install anything...). System itself works fine, but I might end up without battery in few hours . Any help would be really appericated. Thanks!
Edit: managed to install stock through EMMA Flashtool, but nothing has changed. Phone isn't recognized by PC, even ADB doesn't work

Edit: it is charging, even if it doesn't show it. After turning off, connecting to charger and leaving for few minutes it shows more battery now.

You can try going to stock firmware and see will it solve the issue,if not then it is probably a hardware problem

Is there any other way to flash stock than flasthool? I can't get into flashmode. I'll send this phone on warranty anyway, but i have to lock bootloader first
