The highest version available in that mirror link for G2 is 4.5.3 whereas the one asked is 4.7.3. I am also looking for the 4.7.3 version. I came back to this forum after a long time, I can see that my wd tv has 4.7.3 loaded. I loaded that sometime back in 2011/12 or so.
The current task that I want to accomplish is to make the WD gen2 connect to youtube using a DLINk HWA-131 adapter (which is RT8192U I think).
Thanks and regards,
