I have everything I need to complete the untethered jailbreak for 4.2.1. But when I get to the section, "exploiting with limera1n", it restarts the phone without going to the next step. I've followed all the steps and still no luck. 1. I restored to factory 4.2.1 2. Did the tethered jailbreak using redsnow 0.9.6b4 w/ the 4.2.1 IPSW 3. Downloaded all the necessary MAC files (4.2.1 Full, 4.2b3, and redsnow 0.9.7b6) 4. I checked Cydia and I have my SHSH blobs saved for 4.2b3. Keeps getting stuck on the exploiting with limera1n. Any ideas?
