IBOOTER (console for iBoot)

What is iBooter?

iBooter is an interactive console for iBoot (the apple bootloader). Most of you would have used iphuc, which uses iBoot. However, it's dependant on iTunes the mobile device library and can't get replies from iBoot, which results in one way communication, where you blindly say cmd setenv foo, but you never know what happened.

With iBooter you can debug phone booting issues as well as run it in Linux/MacOS/Windows without iTunes installed. You can use iBooter to read memory/write memory, load ramdisks, change your wifi mac address, read files from nand and much more!

Where to get it

You can get a copy of the binary from the following:

You must put your phone into recovery for this to work. Turn off your iPhone then hit power and quickly hold home until you see the iTunes plugin screen. Type fsboot to get out of recovery.

Boot Message

This is what the boot message should look like (besides my pwn message):

How to

Change mac address

Download iBooter, connect to iBooter and type the following: (replace xx:xx:xx:xx:xx:xx with any mac address)

setenv wifiaddr "xx:xx:xx:xx:xx:xx"
printenv wifiaddr
saveenv
fsboot

It will look something like this:

 Entering recovery mode, starting command prompt
 ]
 ] setenv wifiaddr "01:1c:b2:1c:2b:40"
 setenv wifiaddr "01:1c:b2:1c:2b:40"
 ] printenv wifiaddr
 wifiaddr "01:1c:b2:1c:2b:40"
