Samsung I8510 auto switching itself off problem

[SrviRuS]

I have a Samsung I8510 phone and now it began to switch itself off ( doesn't switch itself on after switches itself off ). I fully flashed phone using Apollo 6.05 with I8510XXIA1 Nigeria Firmware but no success. It still switches itself off.

I don't know whether this is a software or hardware fault.

Please help me to get this solved.

if anyone have any solution for this please reply here or to my e-mail addresses [email protected] , [email protected]

thank you

after flashing same problem means its hardware problem only check the on/off switch track and also check any water damage?
