I have the latest Flashtool installed, and both my V's are updated to 9.2.A.2.5, with the boot loaders unlocked on both.

I rooted both of them before the update (can't recall how I did it or where I got the information.) Now one of them is rooted and running Avast Antitheft; no problems there. The other, however, just won't root. Using the latest flashtool, which installs TowelRoot on the phone, the phone reboots right after I press the "make it ra1n" button, indicating failure to root.

Here's the log I keep getting in Flashtool:

And it just goes on and on like this. What am I missing or doing wrong?

SOLVED!
SOLVED! Here's how it turned out:

I found this...

http://forum.xda-developers.com/show....php?t=2798411

... which didn't work - at the first few attempts:

a. Installing Towelroot from internal storage using the built-in file manager seemed to be in conflict with... well, Towelroot being already installed.
b. Chainfire's superSU kept giving me an error message.

So I figured I should uninstall both using the phone's app manager and try the instructions in the link above from scratch, and voila! Here's the log:

LT25i noob
Please help me out...I have been searching this forum for 3 days now and cannot find a straight forward answer, every thread says something different and I am confused as hell now!
I have the LT25i on 9.2.A.2.5, bootloader locked, but unlockable, and not rooted.
How do I unlock bootloader, and root, so that I can flash a custom rom?

Wow excellent advice...do you think I just stumbled across all the threads I read accidentally?
It is extremely difficult for someone rooting a different phone for the first time to know exactly what to type in the search bar to get the correct info.
There is not an up to date all-in-one thread for XV noobs
