PS4 version 7.55 gets Mira custom firmware and jailbreak update
the exploit and the payloads from @sleirsgoevy and @_AlAzif work on all 3 versions: 7.50, 7.51 and 7.55. please stop asking if they work on your specific version. it's annoying.

However, they are still early releases with the exploit reportedly taking several tries before successfully running it. But you can expect some fixes in the days to come.
