means U have new bootrom, no way to restore 3.1.2
and no way to update with custom 3.1.3 wich wouldn't upgrade modem firmware
I had such problem and understood that no way to do something and i decided to upgrade via itunes to 3.1.3 and activate it with sim wich operator it was locked (O2), now i have iphone 3.1.3 modem 5.12, activated for using in menu but no network (now i have not iphone - i have ipod)
I'm waiting any solution for 3.1.3 about 2 month, because understand that today new iboot no way to crack

As the latest version is 3.1.3 so itunes will not let you update it to other version, only way is to restore a custom firmware.
