You have to unlock the bootloader using Sony's official method. The flashtool method only works on older devices.
Just google
Sony unlock bootloader to find the sony site that explains how to do it.
Hold volume up before attaching usb cable and keep it pressed whilst you connect the usb to the phone. It should already be connected to the PC.
Make sure you have installed the drivers as the Sony website says.
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

Oh right, first mistake then. The phone will still need unlocking first though I assume?

No, flashing a stock firmware works with locked bootloader

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!
I have two Xperia Z's , Z1(a) - Display is jet black and sim port broken but phone and touch still function as normal. Bought another broken screen Z1(b) - recovered motherboard to replace Z1a. That worked but now Z1b stuck on pattern screenlock and ebay seller does not want to give me password. I have the old screen with fingerprint smudges and everyday I attempt to crack the pattern lock and phone not blocked as i put sim in and able to call phone and answer..
I have tried connecting Z1b to PC to use Sony Update Service software to restore phone back to factory setting but phone is not recognised or charging by PC (does charge through wall socket and Mac USB port). Run SUS>Press Vol Down Button while connecting USB and LED indicates GREEN then RED but software cannot find phone.
{{Run SUS>Press Vol Up Button while connecting USB and LED indicates solid BLUE LED - not sure what this feature is???}}
So I exchange Z1b motherboard with Z1a and when connected to PC, phone indicates charging and installs a driver to PC. Do a dummy SUS test and phone is found by software allowing option to do a factory reset. Re-exchange back Z1b and still nothing - no charge, not recognised by PC or software - so assume Z1b usb port is faulty.
So read about Android recovery mode but i cannot access recovery mode on either of them - Is recovery mode only available for rooted android phones??? I can only enter safe mode (Power+VolDown) and tried the following options but got no response:
1. Holding Power + VolUp
2. Pressing Vol Up continuously after pressing power button
3. Pressing Vol Down continuously after pressing power button
4. Press all Buttons together.
NEXT STEPS:
1.Connect Z1b to a MacOS 10.6 or later and try SUS and PC companion (i have old Mac 10.4)
Any other help or suggestion??? - many thanks in advance.
Have you installed a recovery?
If not then you cant access something that your phone does not have
You will have to root and install one, just follow the link in my signature to get root on latest KK firmware
PS, wrong section, but I have asked the mods to move it for you
Thanks for your reply.
I thought this was a built in feature on android devices - guess am wrong. I will not be able to install anything if i cannot access phone OS.
Looks like i will have to see if i can reset Z1b through Mac Sony bridge SUS, cough up for USB repair OR by chance crack code.
or just read some "how to" / "Tutorial" / "guides" threads to install recovery. Its very easy.
Hi,
I faced with a problem what I never seen before:
The device works normally, its on 28.0.A.7.24. I tried to update with PC Companion, it recognized the device as E6533, and offered new software.
Once process started, it downloaded, then phones rebooted instead goes to flash mode. After it (until next reboot), phone completely gone mad:
overheated, not asked for pin code, also IMEI was not available etc.
I tried with Flashtool too, but holding VolumeDown not works. It close to immediatelly drops the boot screen, and never enter flashmode.
Had anyone meet with this issue? How could I fix it?
Fastboot mode is working fine by holding VolumeUp, but flashmode not.
Thanks for help,
Your driver usb may be update,,new pc/laptop come with usb 3
Hello everyone. I am in real trouble here and I will explain why. I have recently tried to get the custom recovery with a locked bootloader (philz touch) on my device by following a thread. As far as I know I followed the guide properly but when my device rebooted it bootlooped 10x and then when my device booted it froze at the lock screen and restarted. now my device bootloops several times before boot and once it boots I get 1min at the most before it freezes and restarts. Also sometimes it fails to boot at all and it gets stuck in an infinate bootloop and I have to pull the battery. when I connect it to my laptop with a usb cable it is only recognised if the device boots but I only have a few seconds because the phone reboots and disconnects when I try and enter recovery or download mode my screen goes black and the only way to get of this is to pull the battery. I have also tried to connect to my laptop when on this black screen but i have had no success. If I turn the phone off and connect it to my laptop via usb when I am on the "battery charging screen" it appears on my computer as a unknown usb device. i do have all the drivers ect. my device is rooted with baidu root if that helps. ive heard of a little device called a usb jig would that be useful to me? sorry if this is not worded very well or looks like a book. Im not a idiot but not quite "tech savy" i would like to think i am somewhere in the middle. I have been using this site for years for various devices and always managed to succeed. help would be apprecited. Thanks
UPDATE: I have tried to factory reset from the settings but for some reason the button is greyed out and it wont let me press it! also I cannot connect to wifi or mobile data these are greyed out aswell and when I try to connect via the sliders in the settings menu they are also greyed out!!!

Hi, you need an unlocked bootloader for it to work properly. You can find how to unlock the bootloader by going to Sony's website and see where it says to unlock the bootloader or just look for it on Google. To get back to the stock rom (Android 4.4.2 KitKat), you will need Flashtool and the stock rom. You can find the rom on Google by just typing "sony xperia e1 d2005 stock rom". To get the recovery just try looking for it on XDA. And USB Jig will not work for Sony devices. USB Jig is only designed to work with Samsung devices.
