If i were you i would download and install Rebug 4.78.2 rex not D-rex.
Once on rebug i would convert to DEX so you dont have to spoof firmware.
Install MultiMan and PsnPatch.
Use Edit your Psnpatch.cfg with your new IDPS and PSID.
or if you have no use for DEX go with the latest 4.80.1 Rebug rex. and you can always use cobra if you need to sprx.
