I updated my iPhone 4 to iOS7 and hated it. Since then I have sourced an iOS6 logic board and swapped it over. I then JB'd it with Redsn0w and tried to save blobs.
Redsn0w couldn't find any locally, nor with Cydia but Tinyumbrella found one which is iPhone3,1 7.0.4 ...
I'm unfamiliar with blobs but it looks like an iOS7 blob. How did it come from an iOS6 logic board?
Are they stored somewhere other than the logic board or has it come from iOS7 backups on my Mac?
