How to get AES decryption key for MSD upgrade file?

[theubusu]

Hello,

I have seen that other members of the forum had managed to make a decryptor for MSD fileshttps://forum.samygo.tv/viewtopic.php?p=44039. However, the key included with it is for 2014 Low-End series T-NT14MAKUC. So - how can i get decryption key of other 2013 or 2014 TV? I have full access and root. I have tried searching for it but nothing came out..

Thanks in advance.
