What is iReb

On February 19, 2010

iReb is a tool (created by iH8sn0w. ) for Windows® that will put your device into a pwned (jailbreakable) state so that you can upload custom firmware to it.

How does it work?

It uploads 3 pwned files using iTunnel so that iTunes can accept custom IPSW firmware.

For S5L8900 devices, it uploads the following:

  • WTF.s5l8900xall.RELEASE.dfu

For S5L8920, S5L8922 & S5L8930 devices, it triggers a heap overflow and uploads a pwned iBSS.

iReb supports these device:

  • iPhone 2G
  • iPhone 3G
  • iPhone 3G[S] (old & new bootrom)
  • iPhone 4
  • iPod Touch 1G
  • iPod Touch 2G (MB & MC)
  • iPod Touch 3G
  • iPod Touch 4
  • iPad
  • Apple TV 2

It’s a very useful tool to fix unknown error 1600, 1601, 1602, 1603, 1604, etc.
