Rooting xperia pro android 4.0.4
1.Flash xperia neo v kernel 4.0.3 firmware .562 ONLY using Flashtool using MK11i Xperia neo v 4.0.3 firmware .562 KERNEL ONLY.
2.Turn on the phone (u will see blank display,ignore but must comfirm it turned on,bcoz u will feel vibrate)
3.Root using doomlord method for ics (Here XDA or Here with updated busybox and su v3.1 by me)
4.Make sure on Mass Storage Mode,usb debugging,unknown resource,and run the runme.bat
If it say adb expired or waiting device too long after plug ur phone, on cmd inside folder "file",use command "adb kill-server" later it try to detect back or using task manager,kill "adb.exe"
5.After it say done rooting,i think after 2nd reboot,remove battery and unplug usb.
6.Put back ur battery,and by using flashtool,flash back xperia pro 4.0.4 KERNEL only to the phone download u can get the kernel from SlingFile,4shared . Thanks to Snoe II for sharing.
the sixth step didnt work for me, changed the kernel to MK16_4.1.B.0.587 and it worked. Though in my case I had already updated my phone to the latest version before i rooted.
heres the link to the kernel:
