Good info you've posted there, but what about the part of iTunes? iTunes need to be use to perform the downgrade, the latest version of TinyUmbrella can by TSS server get the iOS signed, but there is still the error 1013 which iTunes popup when installation is about 30% to finish, and then putting the iPhone in recovery mode.
What do we do about that error? Ignore it and then run RedSnow and follow your provided step by step guide?
