-1 Error of Hardware failure . it actually comes when Baseband (IMEI) of the IPhone corrupted . you have no option rather than replacing the iphone or Change the logic board inside. if you are using the mac then connect the phone in recovery mode and go to system profiler and then go to usb then select the iphone .this will show the serial number there . if the serial number show ffffffffffffffff like this then change the phone . otherwise we can try to recover the iphone .

where do i find system profiler? also, is changing the logic board expensive?

chantee hunt,

yes it cost approx near to phone itself. so buy the new phone or visit the apple service centre to replace it . it will cost approx 200$ . if your are using mac then press the shift+command +u. then you see the utilites folder, open the system information . choose the usb inside then iphone . after selecting you will see the iphone information

error code 1 is a modification code, I have only seen this code when a phone has been jailbroke and not for hardware mods, but I have had some bad luck with color conversion kits, they look real good and I have done this to my I 4 but I have installed many that never worked right out of the box, I caution people on this Mod as the parts are generic and a slight risk with your money, Do I think the color Mod caused your problem ? I dont know, but I would reinstall the factory parts and see if that takes care of it.

Did you fix your error? I have come across the same error and would like to know how you fixed it.

This is a Hardware problem. when you remove the shield of Bottom side under the Charging jack. This is actually a problem of supply to Baseband Chip or either baseband is faulty. Beside the baseband chip there is a Golden crystal ic who supply the power to baseband . main this could be the reason .

hi I am having same problem with my iphone4 caused due to changing the body colour but I am having the serial no. of my phone please help me to fix it thank you.....

this is not the reason of issue . during changing the parts you done something wrong to logic board thats why it giving the error during restore. Take the Logic board out from the phone and connect the good battery and charging jack then try to restore the phone without any other thing . check out the error now . if same problem then it is a logic board issue otherwise something other part malfunctions .
