If you are using Android 4.0.4 then to root your device you have to flash the kernel from Android 4.0.3 first. Then root using the Doomlord script and then flash the 4.0.4 kernel again.
The instructions are given in the very fast post of this thread. you can check that.

I think after rooting 4.0.3 , you can update over the air to 4.0.4.
i followed this method only and working fine.

Hello, I am currently coming back from an unlocked bootloader and a custom rom. Apparently, the ROM caused issues with my ray including app forced closing and random system rebooting. I tried completly wiping my device (cache, data, system, sdcard) and flashing stock ICS and GB with flashtool but the problem still presists.
Now, I decided to relock my bootloader and follow your steps for flashing the latest ICS update but when I try to "repair" this TW version with SUS, it tells me that I already have the latest update. I tried PCC but it keeps saying it cannot connect to a server or something like that. I tried the PCC repair link but when in "prepare" the error "unable to install or start phone software update components" comes up. I'm pretty stressed with this software "support".
Please help. Thank you in advance

hi, Want to download the ICS for Xperia pro. Don't know which keyboard layout. I'm from India. So, which keyboard layout should I use? Europe keyboard layout or Africa keyboard layout?

senyakr if you are on original firmware that came with the mobile then See the first page of this guide and follow the green lines and see what's your customization number is
Ev1 try to search for an "a" version
Subhash Here you go
toumbo i have no idea bout that, each rom has different instructions for installation
mydegeneration , You flashed ICS using flashtool , now you wan't to reinstall using SUS ?
sunilkn006 Are you on original firmware that came with the mobile ? follow the green lines given on the first page ( follow it ) then you could risk to install any layout

I really just want to repair my phone. My issues are big because I can't do much with my phone. Not even send a simple text message without the keyboard force closing on me or the system rebooting. I refuse to believe a simple and safe custom rom ruined my phone like this.

But a custom rom can really ruin a device forever. If not properly installed or not properly coded could damage the whole mobile or its components.
Do one thing, try to flash 4.0.3 and see if you face the same problems

kazel if you start checking the comments of this thread from page 1, you wouldn't find one single person complaining about the issue that you did.
Moreover i hope you saw the warnings ? You are doing it at your own risk !!
Almost 90% of the users installed it in the very first go and few face problem that too with flashtool and not with the mobile
This sim problem has happened with many users who installed ICS using pc companion ( They didn't use flashtool )
Check these threads
So many people have used the rom you flashed including me and i didn't face any problem
I am sorry but you will have to contact service support center
I could help you with one thing atleast
Did you follow the green lines written on the fist page before flashing anything ?
