HT-D5500 firmware downgrade

[miixa]

Okay so i've been searching for a while for a working solution. Tried 2 different dns servers with either 601 or 800 error codes when trying to download from internet.

Anyone recently tried to downgrade HT-D5500 firmware and was successful? Should put money on a table for a successful solution?
