I installed CC2.0 Pro in version 7/8 PAL console several months ago running R29/31 firmware with no problems until last week when 6x reset (hardware sleep mode) was initiated by someone else - I'm taking their word for it that this is all they did. Since then the chip will not restart, on power up I only get a black screen, discs will not read. 3x reset from here gets original PS2 start up screen but still discs will not read. 6x reset goes to original PS2 start up & discs will boot (originals only). My first thought was that the chip had been reset to no firmware (only one flash since new), but I am not even getting any sort of CC menu screen to install firmware. Any clues? Has the chip failed?
