Description
Onkyo DV-HD805 / Integra DHS-8.8 – Version 4.0 via Toshiba HD-XA2
Onkyo never published a downloadable 4.0 ISO (phone-ordered discs only; any “Onkyo 4.0” files found online were binary-identical to Toshiba XA2). Multiple AVS Forum / HT Shack reports successfully flash Toshiba HD-XA2-4000N and afterwards show FW 4.0/T23T.
Changelog (Toshiba HD-XA2 Ver 4.0)
- Addresses disc playback related issues (including AVC/H.264 1080p24 “jaggies” reported vs 2.8/3.0).
- Play-state specification change when pause continues for 3 hours.
- Cumulative over XA2 2.8/3.0 (1080p/24, High Bit Rate Audio, network content, HDMI/DVI).
Also available
- Official Onkyo/Integra Ver 2.8 CD listings (stock, non-cross-flash).
