Have an OTB1.1.2, trying to activate and jailbreak. Got the Oktoprep not installed error message, although i did install Oktoprep. Decided to start all over again..
Now itunes does not recogise my iphone! I have another iphone and it works fine, but this one doesn't! Been doing what other threads have suggested:
1. Change USB Port
2. keep restarting iphone
3. keep restarting itunes
4. uninstall/install itunes
none of the above work. can anyone advise me please?
