Thread: Z300 hangs after SIM unlock

Hi guys,
i used this s/w to get an MCK code for my Z300 (can't recall the s/w name at the moment), entered the code - and got a happy unlocked phone. after a while - i started copying my contats from the old original sim to the internal phone book - replace to the new sim to copy the contact back to the new sim - and from now on, the phone just got stuck after running for about 5 seconds.
i tried to switch back to the original sim - no luck.
when i'm removing the sim, phone seems to work (by work i mean of course - not stuck).
i tried using 'QUALCOMM UNLOCKER' to get it fixed - no luck as well (after messing with the s/w for a while - i get it to work only if i hit buttons while i'm powering on the device).

any ideas?

Thanks.

if it is working without sim reset it using *2767*3855# if it is not working with or without sim,u must flash it

thanks (i just wanted to say thanks, but the i failed to reply because i didn't had minimum characters)
