So, some years ago I asked about how to update the firmware of my PS3 in this thread: www .psx-place. com /threads/help-updating-firmware-and-softwares.12113/ I followed all the steps: Just download habib's 4.81 CFW PUP file. Using a fat32 USB key (not a hdd) on a PC, create the folders & copy the pup file so at the end the path on your USB device should be exactly like this, in caps letters. X:\PS3\UPDATE\PS3UPDAT.PUP If the path is any different it won't work. Plugin the usb key into the ps3. Remove any disc from the BD drive. Disconnect from Internet. Go to the XMB->Settings->System Update. Choose "Update from storage device", the next screen should show the name & version of the CFW. Go ahead with the update. On reboot, you are done. But on reboot, while XMB works fine, whatever game/application I open triggers a very loud sound from the monitor and all the screen goes black. I have no clue what happened... I just downloaded HABIB_481_PUB_102_CB750 and followed the guide, so why such a simple operation stopped my PS3 from working properly? Could it be because multiMAN and webMAN MOD aren't updated? I tryed to launch webMAN MOD 1.41.41 Updater, but it does the same thing: noisy sound and black screen.
