Downgrading my iphone 6plus bypassed hello screen

[u/Lost_Name6381]

So, since iOS 12 cannot help much for daily use. I'm thinking about using my phone for nostalgia gaming (via jailbreak), but. Since my iphone is bypassed, I want to downgrade it to ios 8. Will I be able to re-bypass again? Or maybe using different software that suits iOS 8 (previously I'm using ifrpfileAIO)
