I get always a blackscreen .. -.-

Help pleas

You can't use the REBUG spoofer, you can get it from the REBUG.me website just type in .2 in the search bar, then go into REBUG toolbox and change system mode to REBUG, and your all set!

If you're on Rebug 4.21, do this:

1- Install Rebug Update Package 0.2:
Download Rebug_Update_Package_0.2_4.21.x.pkg from Rebug's website, verify the md5 hash, install it from Package Manager, launch it under the Game column and follow the on screen prompts, the screen will freeze for a while when you select Yes, do NOT force shut down your PS3 at this stage or else you will get a nice and shiny RSOD! Just be patient and wait for it to finish what it's doing, it will reboot if needed when finished. This will update the built-in spoofer to 4.41. Once the PS3 has rebooted, you can delete Rebug Update Package from your XMB as it is not needed anymore.

2- Activate the Spoofer:
Go to Package Manager > Install Package Files > PS3 Hard Disk and install Rebug Toolbox. Launch it under the Game column, go to Selector and change System Mode to Rebug, this will activate the built-in spoofer to prevent accidental updates to OFW >3.55 and allow PSN access (with ban risk).
