r/PS2Modding

I bought a PS2 fat that supposedly was cleaned and unmodified but it had a modchip (you can guess how i found out)

Currently i have no replacement yet but I have freemcboot and an internal hdd, so is there a safe way to remove it? I do have soldering kit but I only used it for replacing OG Xbox capacitor, my guess the chip would an Aladdin since it is common one

I have OPL and Launchelf, but I can't install applications because I don't have access to the files on the Memory Cart.

So I want to know if there's any way to install them exclusively from the USB drive.
