[NesestIph]

I got an iphone 5S which i sucessfully downgraded to ios 10.3.3. But i want more and read that it possible? Anyway it tried ios 8.0.2, and 9.3.5 both comming with the same outcome. Ramiel says it succeded but in reality it in recovery mode and after restarting it boots to ios 10.3.3. If i select ios 10.3.3 it says failed to patch iBSS and iBEC aswell as the expected 32 & 64 (or something simmilar) but got 3 & 3. Please help or at least tell me its impossible. Thanks
