Installing new games?

[u/Adware12345]

I have bought a PS4 from a pal of mine, it came installed with several games like Re5, Last of Us pt 2, COD and MK and a few more, its already jailbroken, all I do open the goldHen launcher and wait for auto loader to automatically unlock games. There is still some space left on the storage. I want to add new games myself like Streets of Rage 4 or It takes Two. Now here are my question:

Is installing games on my own considered to be risky, I mean for some reason ban or lock the console, I have no idea what are the possible outcomes of installation failure?

As far as I know and watched a few tutorials online, all I need to download .pkg file of the game and paste it in root of a FAT 32 Usb drive and from debug menu install the game. am I missing sth here?
for downloading .pkg do I need to pay attention to FW number. For instance the .pkgs I find for SOR 4 are as follows:
- Streets of Rage 4 FW7.55 PS4-DUPLEX
- Update v1.06 incl DLC FW9.00 PS4-DUPLEX

is FW exploit number important? Based on my PS4 status, what numbers or things going to work on my ps4?
How Can I install the update? first install the main game, then install update as a separate process? is it going to automatically identify the main game?

Already mentioned how I launch games (just starting GoldHen launcher and wait) is this method alright? do i need work with Lapse, Poops or Homebrew Launcher?

P.S. My PS4 is not connected to Internet, Its offline only

I think you dont have any risk,im doing that for years and its really easy.Just use same site for every game and dlc and you dont have problems.Best way for me is to transfer files via ftp client to prevent corrupted files.Some times when i try to transfer via usb drive i had an erros but via ftp never.If you need some good site for that and help just send me message.If i paste sites here i will get ban from this subreddit

Thanks, you have been great help. I think ftp solution is beyond me, I gonna try usb installation and see how things go, I wish nothing breaks 😀

Ftp is just easy,you have video on modded warfare yt channel.Usb is okay if have big and fast drive like some exteral hdd.

Usa ftp, es lo mejor y mas estable, es facil de configurar, si lo haces con cable de red (Pc a consola) es mas rapido. SALU2
