    I have 2.2 5G77 and the ipsw for 2.1 5F138, and every time I shift-restore it says it cannot do it (5). Most of my issues are I think with the 2.2 FW so I think if I can go back to 2.1 I'll be golden. Ideas?

    There are far more issues in 2.1 and many less features. Are you on a mac or pc?

    PC. Some apps I want don't work on 2.2 (i.e. SNES emulator).

    I disagree. 2.1 is more stable than 2.2 in my opinion, if you can live without the new features of 2.2.

    To downgrade put into DFU mode first and then shift-restore to clean 2.1 firmware before jailbreaking.

    That video says it shows how to set up SNES. I think most people used the NES one. Let me know if it works and we can try something else.
