[Q]Update failed and cant switch on phone - Sony Xperia T2 Ultra

Okay, I was using Sony PC Companion and trying to update my Xperia T2 Ultra. It kept saying me that update fails and every time I turn on my phone, It always says The software update failed. I tried to reconnect my phone to my computer but my PC didn't recognize my phone. What should I do? I can't even use my phone normally, need help ASAP.

either unlock your bootloader then use flashtool to flash it back or install PC Companion and try it again. When using the PC companion go to support zone then click update phone then chose the highlighted(blue) word "repair" then just follow the prompt

for repairing the arc, it must be turned off, just open up pc companion, then it will instruct you how to connect your arc without turning it on(usually you hold down the back button while plugging it into the usb). Make sure to select the correct phone type when prompted(chose xperia arc). also make sure that your phone is atleast 50% above battery.
Follow the prompt, you cant go wrong.
try it now.

just helping out a fellow new arc users. we all have been there, i can understand the panic and frustration(also felt that way when my arc bootloop on me lol).
Hi - Forgive me if I'm saying stuff that you already know...
-Switch your phone OFF. Leave it for 30 seconds or so..
-fire up SEUS.
-Select Arc (LT15 or SO1C depending on which you have..)
-HOLD THE "BACK" KEY down on your phone WHILE you plug the USB cable in.. Keep it pressed until SEUS tells you to release it.
SEUS will then either update your phone, or say that you have the latest software.
If it says that you have the latest software then you will get an option to repair your phone..
Use it!
If SEUS doesn't work do the same with Flashtool... it's like SEUS but not made by SE!

while the phone is off connect it to pc, open Flashtool in fastboot mod. Flash a stock FW.
If that doesnt work open PC companion it should ask u to repair it if u follow istructions.
@deniel: It doesn't connect neither PC Companion or Flashtool. It doesn't enter in flashmode.

Have you pressed the menu key while connecting phone to computer?
bricked phone have to be OFF(remove battery and put back if necesaary if it's stuck at sony screen), prepare flashtool ftf and follow onscreen instruction and the flashtool will revive the phone.
Or maybe you could show the error msg from flashtool.
you are really bold in trying the untested bootunlocker, this definitely is a hard brick. hope you get out of this one.

Sorry for asking again: You started FlashTool (v0.9.8.0), clicked on the flash icon, selected "FlashMode", chose a firmware for your Arc S, activated "No final verification", clicked "OK", pressed the back button on the switched off phone WHILE plugging in the USB-Cable?

Sorry if we repeat the same thing, but it must work like this: you hve the phone off and unplugged. You open flashtool, select the flash icon (flashtool), select the FW, and it tell u to plug the device to pc while holdin back button.
Sure u hold the the backbutton while pluggin in? and after have selected the FW ?
You've to select the firmware first before plugging it in.

Yeap. Is that I don't know how to restore my .TA file. I know what I changed but ... how????
Help me please??
LT18i
Locked Bootloader
Root access
Had CMW via Xtools, so when I replaced the rom that disapeared!
The problem is that I've forgot to run the 2nd part - device optimization, and now the touchscreen simply doesn't work...
Can't do nothing - USB Debugging is on by default (never forget that I can't touch the phone)
Can't upload another rom via flashtool, the only thing I'm able to do is change the kernel with the 1_lt18i_4.1.B.0.431_kernelDowngrade
If I try to put the uptodate kernel, flashtool stops on "Reading Device Information"
Already try to restore it with Pc companion, but no luck
USB device is detecting LT15 on windows!
This is a total mess, I'm lost, and I've googled and tryed dozens of things all day long.. I'm tyred, exhausted, and my 2 day old ARC S is bricked!!
Can someone point me a way out??
Remember:
- USB debbug of (have no access to activate it)
- CMW disapeared when installed this rom, so have no recovery menu
- Bootloader is locked
- Can't flash rom via flashtool
I'm devastated!!
Thanks in advance,
Ricardo

First charge your phone for a while, then download flashtool and sony xperia s official firmware.
As your phone is switched off, press and hold volume down button and connect it to the pc, green led will turn on,then flash your phone with flashtool.
I always use this method when i brick my xperia s.

Try installing PC Companion or/and Sony update service and maybe you could use one of them to recover and install stock rom again
Or if you can't install it using PCC or sus, try flashtool again, because the two sony programs will install drivers , too

DON'T START YOUR PHONE. Turn it off and disconnect from a PC. Start PCC and choose phone update then click small blue repair text/button. When repair is prepared PCC will ask you to connect USB cable to a PC and then to a phone while holding back button (phone must be off). And that's it your phone should be fixed in 10 minutes.

guys,
thx for all response and answers.
i've repaired with PCC, and my phone is back normally.
once again i want to say thank you very much.
sorry for my bad english, and thank you that you all understand what all i mean.
one more request, can you give me a link to download SEUS?
because i have difficult when searching the link in the google
SEUS is a Sony Ericsson Update Service and I think its this file http://www.sonymobile.com/global-en/tools/update-service/ Its probably better as Samak46 said because its not as bloated as PCC and its lighter on the system but both are basically the same so if you've installed PCC then there is no need for installing SEUS.

Dear bjchettri
I do appreciate all your efforts
I have to explain the situation just to make things more clear because it looks like you misunderstand me
when I connect my phone (in all modes "Bootloader, Fastboot, normal, recovery..etc) nothing happens on my pc
even in device manager (i'm using Microsoft windows) the system doesn't show any item for a new attached device or an item for an defined attached driver (which used to appear all modes)
the flashtool needs the system to find an attached device to communicate with (usually the attached device name looks like "android phone", SE android or something this (depends on ur phone brand, model)
now since my system doesn't find any device when I connect my mobile then the flashtool won't be able to communicate with my device (even if i tried to boot my device in all modes "bootloader, fastboot, normal, recovery) by holding specific buttons (menu or volumn down or back buttons)
and if you read my question you will see that i was asking if anyone knows any way to connect my phone using testpoints or something like this because i though maybe I can let my pc to recognize my phone using the testpoints method.
I'm not sure but if i could make my phone recognized by the pc then i will have like 10 ways to find the problem and fix it.
