Hyperdeck Shuttle (first)

Hi all! Please tell me which firmware version is the latest for the very first Hyperdeck Shuttle? I got it by accident in “as is” condition. I tried recording to the SSD, I tried to get a pass-through signal, but it didn't work. Now I want to update the firmware, but I don’t know which one to install because I’m afraid I’ll brick the device. Once again, I note that I have the Hyperdeck Shuttle but not the later Hyperdeck Shuttle II


Thanks in advance for your answers! Mirmih
