This happened to me too but my issue was that 4.84 HFW wasn't actually installed on my ps3 (4.84 ofw). Did you by any chance receive a similar message to this one at the end of your installation of 4.84 HFW: "The system is already up to date. There is no need to update"
If yes, then install 4.84 HFW via recovery mode.
That fixed the issue for me.
Another thing to note is, if it fails even in recovery mode, reinstall normal OFW, then install HFW over that again. Sorta clears out all the modified libraries and modules. Worked for me this way, atleast installing, not enabling lol..

Now that you mention it, when I install the update does not reach 100% to 70 the console is restarted and turns on normal. and not if it is installed well or not
