Thecus N299 Firmware Modifications
From NAS Website
Decrypting firmware
The N299 firmware is encrypted with DES using the key 2008N299. It is possible to decrypt the N299 firmware using DES (more information on DES) command with this command:
/usr/bin/des -k 2008N299 -D "N299_N199_FW_1.00.28.bin" "N299_N199_FW_1.00.28.tar.gz"
The other models seem to use a tar file as their format, but not the N299. I still have to figure out what it is.
