Jailbreak Monte (j-ale-brek mon-t) is a jailbreak that was created by MuscleNerd to achieve an untethered jailbreak for iOS 4.2.1 on S5L8930-based devices. This is a so-called backup solution, because of stalled development for an "untethering" exploit for 4.2.1.

Technical Details

redsn0w sends data (the kernel?) from 4.2b3 via tcprelay.py (from usbmuxd). This kernel is the latest kernel that was still susceptible to the Packet Filter Kernel Exploit.

Requirements

  • redsn0w version 0.9.7 (beta 1-6)
  • An Intel-based Mac (A Windows version was not released yet because the process is "excruciatingly slow.")
  • iOS 4.2 beta 3 (requires a paid Apple Developer account)
  • SHSHs for your device and iOS 4.2b3

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:

  • No Windows version
  • Porting Monte back to 4.1
  • Data-restore with iTunes erases the jailbreak
  •  ? (DRM iBooks etc.?)
