How to 100% fix error -1 in itunes

Thanks! Share it with your friends!


So recently i found myself struggling with an iphone 4 that just would not restore in itunes. No matter how many tries or how much googling i did, i found nothing. However i did end up finding a solution and figured i’d make a tutorial 🙂

STEP 1: you’re gonna want to go to and download the newest version of sn0wbreeze. (note it is a windows only program)

STEP 2: Open sn0wbreeze and create a custom ipsw for your device and the newest version of IOS.
This will prevent updating the basband. Error -1 is a result of a corrupt basband chip. However the phone does work just fine.

STEP 3: Run iReb in Sn0wbreeze to get your phone into pwned dfu mode. This will allow the phone to restore to the ipsw you created.

STEP 4: Open itunes and hold shift, then press restore and select the ipsw you created.

STEP 5: Your phone will look like this when restoring. Just sit back and relax now. You have successfully fixed error -1! 😀

I had an error -1 (and error 48) when trying to restore my iPhone 5s too. I managed to get it working again by cooling the phone down a lot (i used an ice pack – normally for injuries) and then doing the restore via iTunes while the phone ist still very cold. I read this online and thought it was a bunch of crap but it really worked for my phone.

Obviously you should be careful not to cause more damage by cooling it too much. Hope it works for you too. Good luck.

Слободан Бранковић says:

for people asking, this is for a4-based devices only. ireb/sn0wbreeze uses the limera1n exploit, which is only for a4 devices (ipod touch 4th gen, iphone 4, ipad 1 and the 2nd generation apple tv).
