Help/Support How to create signed .IPSW file using saved shsh blobs?

Alone_smiling · May 1, 2018

Hi guys,

I have a iPhone 6s and I want to freshly downgrade ios 10.2 (with NO shsh blobs, dont have save shsh for ios 10.2). If that is not possible then I have saved shsh blobs for ios 10.3.3 and I want to create IPSW file like in old days using saved shsh blobs and i can use itunes to restore without issue.

however After spenting hours i couldnt find any guranteed solutions.

NOTE: IN PAST WITH THIS PHONE when I HAD IOS 9.3.3 JAILBROKEN PHONE i tried to upgrade to 10.2 and that tutorial turnout to be outdated and i lost my jailbreak. so this time I want to get everyones experience and experties before I processed.

Thank you,

Regards..
