[Q] Xperia T Boot-Loop after Update

Heyho!
I searched almost the whole day & web to find a solution for my problem, and you are my last instance.
My 1 day old Xperia T got into a Boot-Loop, and only the Sony-Logo shows up after starting the phone.
Previous procedure:
I installed the Sony PC Companion 2.1 and updated to 7.0.A.3.195, after this the phone went into the loop.
Now i can't flash any other software because USB-Debugging is off, and i didn't root the phone yet.
I tried to flash back to LT30p_7.0.A.1.303_Generic DE (found it here) but without Debugging = no flash.
Do you have any idea how i can flash or use any other FW without Debugging or Root?
Flashmode and Fastboot mode work in Xperia Flasher!

If you can stand loosing your data you could try a factory reset via recovery.
Info on how to access recovery menu is in the all-in-one thread.
If I helped, hit Thanks!

If you tried this via the official PCCompanion you could always take it back to the shop.
But i do suggest the following
1) Uninstalling pccomapnion
2) Redownload and install PCCompanion
3) Repair phone via PCComapnion. (You do not need USB debbuging for this)

I can't even enter Recovery because it immediately restarts after the Sony Logo!

The PCCompanion doesn't even recognize the phone because it always restarts. There are only 2 modes: loop or off.
I will return this brick to the shop, thank you for the proposals!

You cant enter recovery if you have not unlocked the bootloader, rooted and installed Recovery

Your phone needs to be turned off for PCCompanion to flash it....Just go through the steps to update software and choose repair

I know what you mean, but when i plug in the USB-cable, the phone automatically turns on.
The menu is like this: SEARCH -> CONNECT (i plug in the cable) -> RECOGNITION -> at this point the phone is on for a few seconds
but it turns off and aborts the update!
This error appears: "PC Companion could not connect to the phone... please read the document troubleshooting".
But no point in this document helps me. There are only proposals like:
-use another USB port
- turn the phone off and on again
- Use another USB-cable
Seems like Sony bricked it with it's own software

Take it back to the shop then

Did you try :
while device is power ON
Volume Up + POWER (for 10 seconds) -> resets the battery, its like removing the battery and putting it back in [device will vibrate once]
Volume Up + POWER (for additional 5 seconds, total 15 seconds) -> will power off hard, device will power down [device will vibrate thrice]

You don't have to. You have to put the device in fastboot or flashmode which you reach by holding either vol-up or vol-down BEFORE respectively WHILE hooking the phone up to your pc.
But as greg said, undplug and completely power off your device and put it aside. Then start PC Companion and chose repair. PC Companion will then guide you through the steps necessary to get your phone to a state where it can be reflashed.
because it always restarts. There are only 2 modes: loop or off.

Not true, it does not restart by itself in either flashmode nor fastboot mode
As pointed out above, theres fastboot mode and flashmode which bypass the failing OS bootup

You obviously have no clue what a brick is. You have a bootlooping device which is nowhere near a brick. But that's probably a detail you're not interested in.
Try to follow the steps above to repair (=basically a full on, clean reflash in Sony vocabulary) your phone and get rid of the bootloop.

Hi guys.
first ever post in here!(because nearly all of the time i've found an answer here!! cheers!)
i've had exactly the same problem and been looking all over for a solution as i also have the boot loop problem occurring. tried the repair options in pc companion and also SUS. if i'm right the battery has to be above 50% to update and i'm pretty sure it's drained. i remember when flashing my htc one x when that was stuck in bootloop with low battery that to get enough battery I made a battery loop batch file which charged the device. however this was in fastboot mode and i don't think i have that option on my Xperia T. is there any way to charge the battery so as to attempt another repair?
Thanks in advance!

Just leave it plugged in. But i have used pccompanion when the battery has been as low as 10%.
I think you could try a hard reset. (Volume up and power button for 5-8 seconds, and then keep it pressed for a further20 seconds, untill it vibrates several times) Then try flashing a stock .303 file from the all in one thread via flashtool

leaving it plugged in just continues bootloop. sorry should have mentioned i've tried hard reset. i did try flashtool (0.9.9.0 version?) but it was not picking up the device.

why are you flashing an x10 relock bootloader ftf?
Choose an xperia T stock generic ftf from the all in one thread and place that in the firmware folder of flashtools and choose that when you hit the flash button

tried the flashtool with the relevant ftf file but after an initial connection phase it kept bootlooping back out of 'connected mode'. however i left i (trial and error) and it did start to flash the ftf but initially it stopped around 40% then re-bootlooped. i messed around with vol- connection to usb and power plus vol+ shutdown method (which incidentally did not vibrate) serval times left it plugged in and each time it started but stopped flashing around 92-94% complete. having got frustrated i just thought what the hell and left it to attempt to charge overnight (i say attempt as this method never seemed to charge the device once i had this problem). Anyways i must've done something right (or not!:silly as i tried it again but today there must've been some charge applied as it flashed on the second attempt i tried (the first resulted in another aborted flash) it flashed my T no problem!:good:
thank you guys!:laugh:

Glad it worked out for you.

But you activated USB-Debugging before your phone started looping right?

Press the power button and volume up for 10 -15 seconds.
it will vibrate once, that is like a restart
If you continue to hold for another 10 seconds it will vibrate 3 times. That is like pulling the battery.
Try turning it on after that

Have you flashed anything to the phone?
Have you rooted it?
Have you unlocked the bootloader?
If you dont know what these mean then you will not have done them.
Please plug the phone into the wall charger and leave it for a few hours then try the power and volume up button again. It is essential you leave the phone alone in this time.
Last question, when you press the power button and the phone is on charge does the red LED come on?

OK, try what I suggested. There may be other things that can be tried but if my phone behaved like that straight out of the box when I had not tampered with it I would take it back to the shop and demand a new one. Even we were to "fix" it via doing something on this site I would always be slightly worried I had a defective device.
Is it possible for you to return it?

What kind of shop is that? What country are you from? Thats terrible customer services!
Oh well, dont worry.
Have you installed PCCompanion on your PC? If not google it, download and install it. Also, look in the first thread in the development section for a thread called flashtool. Follow the links in that and download and install flashtool. We will need them if we are to save your phone. Also, they are good to have for pimping your phone later...

Once done it will prompt you again.

Last thing to try tonight
Download flashtool
Goto the installation folder and then into the driver folder.
Run flashtool drivers
Choose nx for ICS
tx driver
flashmode driver
fastboot driver
Then try again with pccomapnion.
If that does not work, download a stock FTF file from post 3 in the first thread of the Q&A section.Choose any file for the xperia t.
Open flashtool
Once downloaded, drag and drop the ftf file into the open window of flashtool.
When prompted attach the phone in flashmode (press volume down when attaching the usb cable)
Thats me for thenight now.
Let me know how it goes, but I wont be back untill the morning

[ STRIKE]Just to add one thing, before you try connecting it in flash mode, do power plus volume up till you get 3 vibrates. That way you know for sure your phone is off. If your phone isn't off it won't enter flashmode[/STRIKE]

You can force reset your phone by opening the back pushing a little button near the bottom with a pen, wait for three vibrations then turn the phone on

Make sure your Xperia SP is Switched off. If pushing back button doesn't help then keep the back yellow button pressed for sometime and along with that keep pressing volume down button and you will boot into CWM Recovery
After that either reboot or shut down the phone and just simply reflash it.
Hope I helped

The yellow button part has already been mentioned...
Furthermore, who says he/her has recovery installed? He/her didn't so your suggestion is rather worthless at this time.
I notice you're trying to help allot of people lately, but try doing so by giving correct instructions rather than telling people what you would do to your own phone in similar situations.
First question should be if he/her has installed any custom ROM or kernel.
If he/her unlocked her bootloader or not and if a recovery is already installed.
The answer to the above questions will decide on how to approach this problem.

If you see properly you can see that he has already been advised to flash 4.1 stock kernel THAT MEANS HE HAS UNLOCKED BOOTLOADER, and if someone has unlocked Bootloader he would definitely have roott access and recovery installed (common assumption)

Or have you tried a different cable? if thats not helped you, im affraid you must bring it to the sony repair. but there's one method you can still do, but you must proceed with caution since you will remove the back panel of your phone. see this link >> http://forum.xda-developers.com/showthread.php?t=2646405

remove the battery for 10 sec or force power off completely by holding vol up down and power button . using flashtool connect the mobile only when it say connect. i mean just select the rom and click flash without connecting the phone . then in a few sec it will ask you to connect the mobile . connect it by holding the vol down button . hope it works
