K530 / w660i not turning ON

Hello all

I have k530i set , i have changed the firmware to w660i and was successfull and its being working for almost 9 months there was not at all a problem

yesterday i switch off the mobile . then when i tried to switch on there is nothing in the screen
the phone seems like DEAD :( :crying:

Now i have setool xs++ and kulakendi client

Now xs++ does not detect the phone when i try to use 2+5 combination it shows .5x continuing something like that

then i tried unlock/repair as said in akshayy.com then i got this log

HOW MUCH A NEW EROM CAN COST

try with different battery, your battery may be the problem, check it just in case
