hourglass…………？

The CF card data issues.

1\Remove the CF card connected to PC, Clear all files.

2\Unzip 10.0 base firmware to CF card, Installed on the B421.

3\At service mode press "stop 0 C",Enter the administrator password.

4\Then update the latest firmware.

NO FORMAT CF CARD!!!

Good luck!

Jack.
