[Q] Boot Loop after Rooting Xperia T2 Ultra using Towel Root

[kronoxz]

Hi all,

This is my bad as I took risks in rooting my Xperia T2 Ultra because I want to use Titanium Backup after migrating from my Xperia Z Ultra.

I used this guide to root my T2 Ultra:

http://forum.xda-developers.com/showthread.php?t=2569904

After rooting using Towel Root V10, I did all the restoring process using TB and then after I turned off my phone, it entered into boot loop.

I did not backup TA Partition or flash kernel before rooting since I was hasty and did not see the use for those. I also do not know whether my bootloader has been unlocked. My T2 Ultra is Dual Sim and on 4.4.2.

I tried entering into recovery but could not enter into it since I did not see the notification LED that indicates when to press the down button. I will try again, but now since I could not go into recovery I was forced to let it die down doing endless boot loop

Can anyone help me solve this problem?

dont wary cure is there

just go to development section and download appropriate FTF
open flash tool and flash it
dont need to mark cach data and app log option under wipe

by not mark you will not loss any app or private data

to turn off the phone do following

1.Detach the micro SIM card slot cover
2.Use the tip of a pencil or a similar object to press and hold the "OFF" button. NOTE: do not use a sharp, hard object that would damage the button
3.Keep pressing the button until the smartphone shuts down

report back if you face any issues

Did that, using the FTF file D5303_19.1.A.0.473_MY.ftf using Flashtool, and not checking any Wipe options

However, now my phone has the red blinking notifications light when it is charging, and it can't be turned on :crying:

Is it bricked? :crying::crying:

Just left it on charging for a few hours,when the led turn green repair it with SUS or flash with flashtool again...

Currently I am charging till I see green light. So far I have been charging there are only blinking red light and steady red light occasionally.

Should my phone recover, and my data all gone, what should I do before I root (using the correct root tool this time) e.g. installing CWM recovery or backing up TA paritition? Is it needed?

When the led turns green flash with flashtool or repair with SUS..and of course your data will be lost...just root with the correct method...depend on your firmware version...
If you're using kitkat,its not possible to install cwm yet...and backup TA if you want to unlock your bootloader
