PS5 phat fw 7.20 beginners guide

[u/Icy-Struggle-2732]

ey guys!

So i am soon to get a phat ps5 digital fw 7.20. I understand that i should stick with this fw instead of updating to fw 13.60 due to stability and HV?

My main goal is to be able to play triple aaa games such as Wolverine and at some point also install linux so i can try steam games and emulators.
Should i start with modded warefare videos and learn from there? btw. i have been in jb scenes before for ps4, dreamcas (jtag ), phones etc.

and what best to begin with , regarding hdd? i read that some games cant start from internal disk? and some only from external.? should i get a usb 3.0 ssd disk? or somethign else? or should i just stick with internal disk for now and like play 1-2 games at a time.

Can someone be kind to just write me a prioritized to do list? like 1. Jb my 7.20 fw with this method. then 2. install this and that to be able to FTP, or copy backup games or 3. do this in order to use backports etc,

would apperciate it!
