It won't do anything. All you have to do is download the 4.70.1 D-REX PUP File and put it on a USB. In that USB, make a folder called PS3. In that folder, make another one called UPDATE. Inside the UPDATE folder, put the PUP file and rename it to PS3UPDAT.PUP. Make sure everything is capitalized that same way. After that, simply go to the recovery menu and update through there to make sure you don't brick your PS3. Let me know if you need any help.
