Software....
have you try flashing the phone in othe box reset all settings like lifetime timer ect.?
if you sure that you already done all software

Hardware....
1st is to check your battery a lot of battery has good voltage using VOM but current problem,2nd thing is to check your power amplifier reason why the phone shot off because the phone doesnt have enough power to register to network...

Good Luck!!!

YEAH... CHECK THE RF CIRCUIT, MAYBE IT'S ON A SHORT CIRCUIT... IT CAUSES THAT THERE IS NOT ENOUGH POWER TO TURN ON THE PHONE...
CHECK N7520, L7520 AND N7505 WITH THIS SCHEMATIC...

And If Not...

Then You Have To Check The Retu (energy Management), Reheat It And Reball If Possible...

may be it was hardware problem because there was shorting in your network section, when you switch without sim the network section will be inactivated,therefore it is don't off, and when you switch it on with sim the power is pulling by network section. therefore it get off. so try to change bettery and then try to check the shorting in the phone. good luck
