[IPSW Builder] Cannot select "unlock baseband"
I have a 2G iphone on 1.1.4 unlocked with ZiPhone and I try to restore to 2.0 until WinPwn 2.0. was released.
I tried all versions of WinPwn including 188.8.131.52. but on the Advanced tab in IPSW Builder everything is "grey" except of Activate Phone and No Wipe.
I have WIN XP SP3 and MS .NET 3.5 installed.
I tried to build custom IPSW file with iPhone1,1_2.0_5A347_Restore.ipsw and iPhone1,1_2.0.1_5B108_Restore but I still cannot select the most important options under Advanced tab.
I would apologize every kind of help.
