Jailbreak Monte

Jailbreak Monte (j-ale-brek mon-t) is a jailbreak that was created by MuscleNerd to jailbreak iOS 4.2.1 untethered on newer devices not vulnerable to the 0x24000 Segment Overflow exploit or the usb_control_msg(0xA1, 1) Exploit. This is a so-called backup solution, because comex had more problems or for other reasons didn't finish his untethered solution on time.

Technical Details

Probably parts of the firmware get replaced with parts of the iOS4.2b3. Someone with more knowledge on this subject please describe this in more detail.

Requirements

• redsn0w version 0.9.7 (beta 1-6)

1. A developer account (Paid US$99 Version)
2. An Template:Wp copy of iOS 4.2b3 (not recomended)

Status

Monte has been released as a beta program to a bigger audience. Each release fixed some problems. (see redsn0w). The current version still has the following issues:

• Porting Monte back to 4.1
• Data-restore with iTunes erases the jailbreak
•  ? (DRM iBooks etc.?)
