I'm sorry I might have come off harsh. I might have done it already, but the last part was a bit confusing.
After patching, there is this command:
sudo ./patch.sh -p
It gives me 2 options to backup.
1) /usr/syno/bin/synocodectool
2) /volume1/@appstore/VideoStation/bin/synocodectool
I backed up both, but I'm not sure if I did something incorrect.
