I didn't, but I've done now with no result
I don't know if this is your case, but some of the latest executables (which you tried) may cause trouble for the system stability...did you try to delete them (with the related config-dir in the $home folder)?
In the worst case, you'll have to reflash your console... with the Pcercuei Rescue Disc the operation should be simple!
(Obviously, you could try to reflash only the system partition, so that your data aren't trashed)
PS: a provisional solution could be downgrade the firmware with the 2013-10-04 release...
