Quick not for those having problems running 1.1.2 jailbreak software even after OKTOPREP was successfully installed:
I tried to jailbreak 2 iphones for the past 2 hours, and after 7times of downgrading and upgrading, ive finally got it working. The phones are fw: 1.1.2. Baseband 04.02.13_G, weeks 46 and 50.
I followed many tutorials to the LETTER in the hopes that i was missing something, mainly the one from Iclarified which alot of people seem to be recommending (something i noticed while trolling through posts)
One thing that's NOT mentioned in that tutorial (and a few others) is that if you DONT INSTALL Bsd Sub and OpenSSH from installer while at 1.1.1, you'll receive an error message after you upgrade to 1.1.2 and try to run the jailbreak software (windows.bat) that Oktoprep needs to be installed.
I dont care how many people will comment that it worked for them, ive tried this process 7 times (counted each freaking time i upgraded and downgraded ) and it NEVER worked without bsd sub and openssh installed.
As soon as i installed them worked like a charm.
hope this helps somebody.
