need help with reviving my G705

Hi ,
I have a G705 Chinese edition
CDA : 1215-8924 R7A
i wanted to use russian language on my cellphone , so i've contacted Sonyericsson , so they've told me it's impossible , then i've followed some debranding guides on the net this one to be exact , after that when i tried SEUS , it told me that there are no new updates for my cell , so i've tried flashing with the firmware that i've found in topsony
Top Sony Forums
it got flashed but it doesn't have the menu,etc ...
and also still the SEUS doesn't work for my cell ,
i've tried W705 aswell , but the same happened
the cell shows R4:4243 on the screen
i can even make phone calls and recieve calls , but there is no UI , i guess i've missed something in the procedure , i'd be greatful if anyone helps me out ,
thank you in advance
