Commands used as an exploit vector
- diags: Until 2.0 beta 6, the diags command would jump to code at the address provided to it. For example, if you sent "diags 0x9000000", it would directly jump to the code at 0x9000000. There is now a check that only allows engineering devices to utilize this backdoor.
- arm7_go: For firmware 2.1.1, the iPod touch 2G iBoot contains the ARM7 Go command, which could be used to run a payload on the ARM7 in the device.
OpeniBoot
There is an open source version of iBoot being made so that Linux on the iPhone will work. You can check out the source here. It is VERY useful if you are ever reversing iBoot and do not feel like finding out what certain hardware registers are yourself.
Remappings
// n88 (3GS) 0x4FF00000 => 0x0 0x40000000 => 0xC0000000
