4.50 is definitely fine, but you'll want to update to 4.55 or 5.05 for HEN. It's pretty simple once you do that. You can even use something like PS4Serve so you can host the exploit locally. It's not permanent though. You'll have to enable HEN again if you reboot or shutdown.
Hen stand for homebrew enabler, the method isn't permanent. For the ESP8266 you need a PC to write the 4MB bin image on to the board. Since you have firmware 4.50 you can either go with 4.55 if your blu-ray drive doesn't work, or 5.05 if it has no problem. No downgrade for system firmware.
You don't need that. You can host it on an Android device, or you can use the online versions. As for downgrading, no, once you are on 5.05 cannot go back.
HEN stands for Homebrew Enabler. Once you enable it, you can install and run games installed through the debug menu.
You have run the exploit every time it coldboot(restart/shut down), ps4 doesn't have a permanent cfw yet. The exploit allows you to run games in fake pkg format, essentially being unsigned.
1. You cannot update (past 4.55 IIRC) if your DB drive is broken.
2. Do not ask where to download here, it will get you banned. Just use google. A f-signed package will be noted as such wherever you get it from.
3. The only dif between 4.55 and 5.05 for me is 4.55 I can let go into sleep mode, my Pro w/ 5.05 I cannot, it will crash. Other than that are the games/updates that require the newer FW. I doubt there will be coldboot CFW for 4.55, but what do I know?
4. There is an exploit for each FW version, they are not interchangeable. If you upgrade to 4.55 and stay there then you need to use the exploit pack for 4.55. If you update to 5.05 then use the exploit for that version.
I really recommend that you read the AIO tutorial. All of your answers are in there, in one spot. Kiwi did an awesome job and I personally feel like you are doing a disservice by not taking advantage of the results of his hard work and ongoing updates to it.
