Hey Guys,

 

Was stuffing aroung with my iPhone yesterday downgraded Cydia extender ( because it wouldn't install) which in result bricked my idevice I had no other alternative but to restore my device

 

Now my question is , is there a way of downgrading from iOS 10.2.1 to 10.2 with prometheus? Stupid me didn't save my shsh blobs as I thought Cydia did that but no. Anyway any info / ideas would be appreciated .

Not possible atm as apple stopped signing the ispw of 10.2 but if you saved your blobls previously then you can downgrade

Blobs would have been the one and only way at the moment, unfortinately you didn't save them so you are stuck on 10.2.1
