[Q] Please help in rooting arc lt15i 4.0.4 - Xperia Arc Q&A, Help & Troubleshooting

sir, I have xperia arc lt15i locked boot loader, never rooted , updated to 4.0.4 from pc companion software. Now I just want to root this phone, so went through many threads , and confused in the dillema that if I have to download whole 4.0.3 rom for xperia arc then flash it, then root it, then again flash the whole 4.0.4 rom, or just have to download only kernel and do the above process.
If just kernel can be used for the whole process ,then whether arcs kernel can be used in arc, because every where in the forum, only arcs kernal's link are posted and no arc 4.0.3 kernal was found by me.
Please clarify the process and doubts, it would be a great help.
Thanks in advance.

There was no 4.0.3 for the arc, that was for the arc S. The arc was directly updated to 4.0.4.
So yes, you need the 4.0.3 kernel for the arc S.

So no need to download whole 4.0.3 rom ???

No need to download the whole ROM. Just the kernel is fine.

[Q] rooting of xperia arc s

Hi, another noobie question, I am going to buy the xperia arc s , can it be rooted and over clock like the one I did on my current xperia arc? Is the whole process from root to flash EXACTLY the same? Most importantly, can doomlord's #10 be installed too?

help down grading to gb from ics

my phone is xperia arc s lt18i build number 4.1.B.0.431 it is ok if i will download the gb for xperia arc LT15i because it has the same build number, my arc s build number is not on the choices for arc s but is has the same build number on arc w/c is 4.1.B.0.431
Since rooting directly in 4.0.4 is not possible, one needs to downgrade to a rootable GB ROM to root. (Skip this step if you are already in GB).
To Downgrade, you need to flash an old GB ROM ftf to your device.

None of them. If you want to root 4.0.4, download THIS and THIS. First downgrade kernel (first link) with flashtool, then use Root toolkit, then upgrade kernel, and you'll have rooted 4.0.4...
If you want to root GB, simple way is to flash .42 and root it with THIS. I still wasn't able to root .62 but I heard there is a way.
P.S. you have to download LT18i firmwares.
