Whenever you want to mess with flash (NAND or NOR), you have to '''make sure you are getting 100% correct, valid, verified dumps.''' | Whenever you want to mess with flash (NAND or NOR), you have to '''make sure you are getting 100% correct, valid, verified dumps.''' | ||
When you don't, and for some reason(s) the dump is invalid/bad, and you are rewriting to flash, you have <span style="background-color:white; color:red;">no way of restoring</span> the console hence making a perma-brick (unrecoverable brick). | |||

Upload your dump to a fileshare host (e.g. http://www.multiupload.com/) and join IRC ef.net in channel #ps3downgrade | |||
Please use this method only after you first tried the above options first (so you have learned from it as well) :) | |||
