Decryption tool now doesn't work on newer firmwares

[kidfrankie1980]

Hello,
I've noted this on the Readme.

NOTE: Optus has patched out the ability to upload unencrypted configuration files, so the only way to upload them is if you re-encrypt them. Apparently the IV and the Key has also changed, which means that the decryption tool now doesn't work on newer firmwares.

I've done your walkthrough and the txt file was all in Chinese(?) letters.

Is there any way around this?

Not sure if this walkthrough covers my sagemcom firmware. See specs below.
