[Solution] No Wifi Problem
i solved the no Wifi Problem. My iPhone is now working again perfectly on 1.1.2 jailbroken.
I have an OTB 1.1.2 downgraded to 1.1.1 jailbreak and accidently executed AnySim 1.2u, after that i had no Wifi. I Tried everything restoring to 1.1.1 or 1.0.2 always no Wifi.
I had only Wifi with 1.1.2, but the problem is how to jailbreak a 1.1.2 without Wifi. The only way to jailbreak your iPhone without Wifi is on Version 1.0.2. So i downgraded to 1.0.2 and jailbreak and acvtivated with iDemocrazy. Then i installed over iBrickr the Terminal Pxl package, to execute the terminal commands directly on my phone.
So open the Terminal Software, and execute following commands to install Octoprep manually on 1.0.2. I read everywhere that you have to use 1.1.1 to use Octoprep thats not right 1.0.2 is enough.
sbin/mknod /private/var/root/Media/disk c 14 1
chmod 777 /private/var/root/Media/disk
Then just Update not recover back to 1.1.2 and use the jailbreak 1.1.2 software and 5 minutes later you have an 1.1.2 version and wireless back.
Hopefully others can solve their NO Wifi problem with this solution too.
