Issue One: If you are stopped at ‘Greenpois0n initalized’ then follow the below solution
Fix One: Retry GreenPois0n again, except when you’ve entered DFU mode, don’t let go of the home button (iSurenix)
Issue Two: After jailbreak, the Loader does not install Cydia
Fix Two: Just download the latest RedSn0w, Click on Browse, Navigate to iOS 4.2.1 IPSW file, Click next, Click on Install Cydia, follow the instruction to put it in DFU. That’s it! The order doesn’t matter: run GP after redsn0w, or run redsn0w after GP (@MuscleNerd)
