[Q] [U] Can't upgrade to ICS
First time I upgraded to ICS was via PC Companion, but i didn't like it so I flashed a ST25i GB ftf on my ST25a (excluded baseband)..
Now i want to flash a ICS ftf to root+CWM and try GB-Rocks rom, but Flashtool (last version) don't recognize it!
Also PC Companion says I have the latest firmware, so I can't update.. Repair option works, but when trying to flash it stops..
What should I do?
---------- EDIT ----------
Official ICS from PC Companion:
GB flashed via Flashtool:
Xperia U (ST25i)_2.3.7 Build 6.0.B.3.184_GENERIC_WORLD
ICS that I'm trying to flash now:

Phone: Sony Xperia U
ROM: Stock 2.3.7
Bootloader: Locked (Not-unlockable)
