Hi, someone of you knows the password for the Unencrypt the FW M3800_N3200PRO_FW_1.00.02 for the NAS Thecus M3800?
I have to modify the file upgrade/version for downgrade from the FW M3800_N3200PRO_FW_beta_1.00.04.2 to the M3800_N3200PRO_FW_1.00.02
The system doesn't allow me the downgrade..
I use this command: /usr/bin/des -k "M3800" -D "M3800_N3200PRO_FW_1.00.02.bin" "M3800_N3200PRO_FW_1.00.02.tar.gz" but the key "M3800" is not correct...
Does another method exist for the downgrade?
Thanks, Best Regards..

Having ssh-access, you can modify the file that is used for checking the current version. That would be the file /img/version
So if you type 'cat /img/version' you should see the currently installed version (e.g. 1.00.04.2).
As you want to downgrade to version 1.00.02, you should make the system think that the current version is 1.00.01. Then 'upgrading' to 1.00.02 is allowed. If you want the system to think that the current version is 1.00.01, you can achieve this by typing 'echo 1.00.01 >/img/version'
Now you can 'upgrade' from version 1.00.01 to version 1.00.02 (and in fact downgrade from 1.00.04.2 to 1.00.02)

Pretty sure the key is N3200Plus
eg.
/usr/bin/des -k "N3200Plus" -D "M3800_N3200PRO_FW_beta_1.00.05.1.bin" "M3800_N3200PRO_FW_beta_1.00.05.1.bin.tar.gz"
What's the reason for the downgrade? I'm running 1.00.07.1 on my M3800 seems to be fine.

You won't be able to change the /img/version file. It's mounted image from /rom/img.rom via looback. /dev/loop1 1024 1024 0 100% /img
Will need to look at another way.
