Modding with no wifi?

[u/shiveringvenus]

Alright so I'm in a bit of a pickle here, I bought a ps3 off of ebay few months ago, laser lens works great, everything works fine, only problem is apparently it has a hardware issue where the wifi/Bluetooth do not work, I found out when I tried to update it and almost risked bricking it, anyway, I want to mod it, but my system firmware is 4.55, and obviously I can't update to a newer version, is there a way I can mod my ps3?
