[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!

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?

I believe I have soft bricked/hard bricked my LG G4 h811 . Can anybody help me?

Okay so I'm a newbie to rooting. And I was on this step where I let the tool install some files to my phone and it said to unplug and pull battery, the next step said to hold power and - volume down button and release power when I see the LG logo while holding the - volume down after a second quickly hold power and - volume down to access factory data reset and settings. So it restored my phone back to factory settings and no root, the video said to try again but the problem is that my phone will power on anymore and is unresponsive when I charge it. So I took the battery out for a min. and the phone turned on but got stuck on LG logo and freezes then it shut off. I tried to boot it up again on LG logo screen, the corner it says Secure booting Error
Error code: 1009
MODIFIED!
And it froze and shut off. Now whenever I try to boot it up it gets stuck on LG screen and shuts off or when I'm in factory reset it freezes when I press yes. I put it into download mode and try to install the LG G4 stock kdz file but my computer couldn't connect with my phone for example, I plug my phone into the computer via USB but nothing, no sound and no charge now it won't turn on at all. I hope this wasn't too hard to understand and I'll greatly appreciate any kind of help, thank you.
.

I wonder if LG or T-mobile is pushing an anti-root tool that hard bricks the devices. My device was working fine until this morning after my alarm went off - Mind you, I have been rooted since the root came out. I unplugged the phone, put it in my pocket, and it got really hot, then it does the same as yours; except, my phone shows bootloader:unlocked when i try to reset it. So, yeah, you are hard bricked. No recovery from what I hear. U got a paper weight. I do not believe any of the G2 or G3 fixes will unbrick our devices. I think it may need a jtag.

LG L90 D410HN Hard Bricked

I have a LG L90 D410HN that is hard bricked, it does not go into recovery or download mode. I had installed some time ago the Lineage 14.1 rom.
I'm trying to follow a tutorial I found here: https://forum.xda-developers.com/lg-l90/general/guide-unbrick-hard-bricked-l90-variants-t3173429, but when I connect it to the pc (without battery), even I have installed all the drivers, it only appears as Unknown Device (Device Descriptor Request Failed) and when I put the battery, it is not recognized just remains rebooting in the LG logo. Any suggestions on what I can do? Thank you in advance.

Nothing specific, I turned the phone off and took out the battery only. When I turned on again, it has been stuck in the LG logo, restarting endlessly and cannot enter download or recovery mode. As soon as I put the battery in the phone, it turns on without pressing the button.
What I think may have happened is I have removed the battery before the system finished shutting down or something like that.

Ok, you are welcome. But for temporary fix the power button probably got stuck pressed so try to pull the button out so it is not pressed anymore.
