I have anZGemma receiver: it is H2 according to the front panel but I get this from the web I/F.

I wonder which firmware should I use for updating: H2.*? H3.*?

Marca & Modello: Zgemma H3 series Processore: Broadcom 7362 Memoria Totale: 243636 kB libera / 312676 kB totale Tempo di avvio del ricevitore: 1d 17:00 Software System OE: PLi-OE Versione del Firmware: OpenPLi 4 (2018-09-01-release-4) Versione del kernel / Drivers: 4.10.6 / 4.10.6+20170623-r0.1

I am puzzled. 

I also need direction about mnaking an HDD visible (sorry if the info is somewhere on OpenPLI web site)

Thanks much for any help
