sn0wbreeze is a utility that can create custom IPSWs to restore to, akin to PwnageTool. It is a GUI of XPwn for Windows written in C#, and is developed by iH8sn0w.

Models Supported

The iPod touch 2G, iPod touch 3G, and iPhone 3GS need to have the signature checks disabled beforehand by having a pwned iBoot. The iPhone 3G and the iPod touch 2G MB Model has to run iREB before restoring with iTunes to a custom IPSW in DFU Mode. The iPhone 2G, and iPod touch 1G users cannot use sn0wbreeze to pwn 4.x since Apple no longer supports these devices anymore.

Devices with new bootroms

sn0wbreeze is tethered on devices with a new bootrom because the bootrom exploit only allows unsigned code thru USB so it requires the computer to boot the device up.

Problems

  • There were some problems with blacksn0w on 3.1.3. These problems were caused because the 5.11.07 baseband requires CommCenter from 3.1.2, and when people would upgrade their firmware they would also upgrade their CommCenter to the version that came with 3.1.3, thus disabling the unlock.

Use of xpwntool

The backend of sn0wbreeze is xpwntool which is used to decrypt the IPSW, patch the required files and then encrypt it back using xpwntool.The tool was broken but it was fixed by iH8sn0w.Some modifications of it has been posted in his github

sn0wbreeze does not use ipsw.exe, an open-source custom IPSW generator created by planetbeing but it does the work done by ipsw.exe manually using xpwntool.

Restoring to a custom IPSW

The security of iDevices normally won't permit custom firmwares. sn0wbreeze and iREB can circumvent this security measure so you can restore to a custom firmware without a hitch.
