First, ensure the compatible Firmwares:
iPhone4S: 5.0 (9A334), 5.0.1 (9A405) and the “other” 5.0.1 (9A406)
iPad2: 5.0.1 (9A405) <--- ONLY WIFI, NOT 3G
Download, version 0.4.3, Read post 3.
Unzip files into root dir, like C:
1. Press, in your keyboard WINDOWS+R (Run windows) and type: "CMD" (Without quotes), and press ENTER
2. On windows is open (BLACK WINDOWS) type the commands withouts quotes: "CD .."
3. "cd cinject_0.4.3"
4. Now your machine will stay that way: (C:\cinject_0.4.3>) <-- DO NOT TYPE THIS
5. Run first command withou quotes: (Submit by CAPSLOCKON)
a. "cinject.exe -i payloads/jailbreak.mobileconfig"
- IMPORTANT. On device, accept the script, and next next finish (without password)
6. "cinject.exe -j payloads"
- IMPORTANT. Wait the backup. Sugest try with blank A5 device.
7. "cinject.exe -w"
8. Try to start Absithe, if you get error database, go to setting and turn on VPN and try again
But if you are not familiar with it, then I'd suggest you wait for GUI version.
