Need some help. Have 3390 NPB-1RB v2.03 all locks unlock but no network signal. Also have 3390b v2.01 and it works. Anyone knows what might be the problem please help.

I was able to get my 3390 with 2.03 to unlock after some problems by using Rolis Noktool v1.9. To get it to work, I had to first use the [Read Phone Info] button, then the [SP] button, then the [Open all] button. This did the trick to unlock the phone and I have tested it with a few different SIM chips that I know didn't work before. As a warning though, somewhere in the process I lost my IM menu and never tried to load any kind of flash to the phone. I do still have v2.03 on the phone, but have not been able to get the IM menu back.
