I found this on dev wiki


"I now also went back and downgraded the modem firmware, i did this by upgrading again to 1.02, then erase the modem firmware, then reset the iphone to restore mode, attach it to itunes to restore, with a hosts alterd location to the version.xml and a location holding the 1.0 firmware !!

so it's possible and, yeah, i agree that apple might have tried to close this possibility for the new firmware.."

does anyone know how to erase the firmware, is there a command to erase the firmware?

please enlighten us!!

please delete this thread
