Old S1 Firmware with Jailbroken PS4 in FW9.0

[format_c10x]

Hello, friends.

I have a Jailbroken PS4 on FW9.0 and I cant update, 'cause I'll lost the Jailbreak

I have 3 S1 unitys. One I use with the Switch, with the latest FW on the S1 and the Switch.
Other unity I want to use with the Jailbroken PS4.

Can I download older S1 FW to work with the PS4 ?

I searched the forum and find a similar topic, but cant find where I can download older S1 FW

I am a disability person, I dont have the left hand and Leg, so the ReaSnow and you, Richard, Its like Gods to me, because I love Games and now I can Play them.

Thank you very much, sorry about the bad english, i am Brazilian.

do you have any trouble using S1 to a jailbroken PS4 with the latest firmware?
can you send a video to show us your issue?
which previous firmware version do you need?
