Mine is telling me how "The iPad is not be restored because firmware file is not compatible".

Do you have a fix for that?

[lizards821]

@avelez71 You downloaded the incorrect IPSW for your device.

Hi! I want to downgrade cause my Iphone dos not recognize ANY sim card. I've been having problems since I updated to IOS5...my "last bullet" its to try to downgrade cause I dont know what else to do. I dont want to jailbreak it and I've never did, so, I dont know if I need to have the SHSH blogs or what's its name xp saved...I dont know if my question even make sense...I hope you undertand...

The other question is DO the simcard need to be inside the Iphone when I go to DFU mode? thank you!!!
