@ErvisGjediku@FCE365 Ok first you need to downgrade to iOS 14.8 since checkra1n doesn’t work on iOS 15 yet.
Then jb with checkra1n, set nonce matching your shsh and downgrade with futurerestore. Restore iCloud backup and you’re all set for the next untethered jb.
@albyvar25 Hi. I try to downgrade my i5,4 from 10.3.3 to 10.2.1 with blobs. I got my device in dfu with kloader and pwned iBSS but futurerestore gives me an error. Can I even do it with with futurerestore or should I use another tool? thx
