Help required in Flashing / Repairing K790i

Hello Friends

I'm trying to repair my K790i via XS++

Everytime I switch off the phone, it doesn't turn back on. I get the red irda light. Then I have to connect it via cable to SETools and click on Unlock/Repair

Now I'm thinking maybe it's a problem with EEPROM. I'm getting following screen when I connect my phone

I checked here Top Sony Forums , but there're 3 different files available for K790i . Which one shall I use ?

when ask to update EROM, click yes and see the difference if it solve your problem, if the problem still comes, give a show out again after updating
