Help on repairing Siemens A36

Hi all.

I'm kinda a newbie when in comes to siemens. I have no problem with a c25 but with a36 i think i ruined it.

(original version was 23)
I tried to unlock it but come out with wrong software. then i flashed/swuped it with the original file x3x_23.xbi but now it won't even turn on. I can manage to get it into service mode and it can still be flashed. the only problem is i can't get it to turn on. any help and softwares to fix the phone will be greatly appreciated.

Thanks :)
