Mojave on HP ProBook 4530s

Hi!
Using the wonderful guide and tool of @chris1111 i have prepared my first USB bootable installation key for install Mojave to my HP ProBook 4530S, so... i'm ready!
But... there is a problem... my BIOS version is F.65 but the guide require F.50 version... my problem is to know how i can downgrade my BIOS to F.50
TRIED ALL the official HP methods to flash BIOS with no luck... can't flash an older version... also the "Win key" plus the "b key" method but nothing... anyone can help me?

Recommand Bios F50 but F65 its OK

Thank you @chris1111 for your quickly reply!
I have tried but, after the clover screen, it show up the apple logo and after 3-5 seconds reboot... suddendly.

There is options to try or just to know whats happen that i can pass to command line?

Hi to all!
I have made one step forward, resetting BIOS options to default i have completed the installation without problem also with F60 BIOS version.
Post install i have used the @chris1111 tool without problem, but at the reboot the system remain with apple logo and bar below without boot...
With verbose option i can see:
IOConsoleUsers: time(o) 0->0, lin0, llk 1,
IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0

And again, some rows up:
GTrace synchronization point 2
Unsupported CPU
Unsupported CPU
GTrace synchronizaton point 3
Unsupported PCH

and also:

apfs_keybag_get:1320 failed to get apfs volume keybag, err = 2

and others similar...
I don't know how to do...

Thank @chris1111 it worked, but now, after use your post installation tool, i'm on the same boat...
The system won't boot...

the latest update package is already test by me and other and its work

I'm using your latest package... where i fail???
I must check the 3000HD patch right?

YES

Thank again @chris1111, i was wrong because i was choosing both the options (0-1-2-3 and 4) but i have to check only 4... it's so frustrating...
Apparently all Is working except the WiFi adapter, i have Atheros AR9285 and i have selected:
Atheros AR9285
WiFi Atheros macOS Mojave
But i can't see my adapter in system preferences - network
Anyone advice?

Hi to all, i'm here again...
In summary, after various vicissitudes I managed (using the @chris1111 tool) to start the system and with the right video resolution.
Unfortunately, I can't get WiFi to work (Atheros AR9285) ... obviously I selected the two fixes in the @chris1111 tool but nothing ... I tried using Kext Utility and KextBeast but nothing.
I noticed that the kext AirPortAtheros40.kext is installed in / system / libraries / extensions but shouldn't be in / libraries / extensions?
Do you have any other advice for me?
Thank you all!
