I feel you bro Don't you have any debug or JTAG pins to move on?

Yes the board has a 6pin SPI header & 10 pin JTAG header, and I can read the chip with SPI, but JTAG access, debugging, and verifying memory contents has been disabled, and the the LB1 and LB2 lock-bits have been set, so its not possible anymore to change any fuse settings, unless you completly erase the chip first. Reading the flash & eeprom contents with the current settings returns garbage (i.e FFFF FFFF )for the complete memory contents
