If you see the following error message on the screen during the jailbreak process:
Unable to find gBdevList

Unable to find fs_load_file
Ignore the errors and continue holding the Home button and wait for the jailbreak process to complete.
Cydia Option Missing in Loader App:
If you don’t see the Cydia option after launching the Loader app to install it then either keep trying by quitting and relaunching the Loader app again or using Redsn0w 0.9.6 RC8 (download link) to install Cydia by selecting the ‘Install Cydia’ from the options.
Greenpois0n recommends a clean restore so if the above tips don’t work then you can try to restore your iOS device if you desperately want a jailbreak as it is not ideal.
