PS3 Flash memory patch stuck at 99%

[LastJoker09]

Hi, I've been following the steps to install CFW on my Fat CECHC PS3, and it went smooth until I got to this point. The background and cursor are not moving either, so I'm asking myself if I should wait or try to reboot the system. It's been like this for approx 30-40 minutes.

System was updated to OFW 4.91 before attempting this.

MD5 Checksum matched when I checked.
