Things You'll Need
Instructions
Download the required recovery files from the SmoothBlog: How to Unbrick Your PS3 website.
Insert the USB flash drive into your computer and format it to remove any files that may be on it.
Extract the file "Lv2Diag.self" from "File 1" of the recovery files onto the USB flash drive. You also must put the file "PS3UPDAT.PUP," which is your system's current firmware version, on the flash drive. Each version will have the same file name, although you must be sure to use your system's current version. You should be able to locate a copy of this file by entering the file name and your firmware version into an Internet search engine.
Insert the USB flash drive into the PS3 USB slot and turn the system on. Wait about 10 minutes until the system shuts itself off.
Remove the flash drive and format it on the computer. Extract the "Lv2Diag.self" file from "File 2" in the recovery files.
Put the flash drive back into the PS3 and wait for it to turn off again. Remove the USB flash drive and restart the system, which should now load properly.
