I upgraded to the latest unofficial firmware and tried to downgrade to r2089.
just to see if 1080P upscalling was working or not as stated in topic:viewtopic.php?p=10571#p10571
now with me also the hdd is not to be seen,
so I connected to my pc (after also trying to downgrade to r1757)
as i`am writhing this i`am copying all my files to the pc then i`ll try to fix it with chkdsk.
see if that helps.
this problem is my own fauld i should not have downgraded it.
but it should be possible.
I think the new unreleased firmware changes some info in 0-sector of the drive.
i`ll let y`all know tonight how it went because copying takes still about three hours.
a`lot off *.mp3 stored on it. update
downgraded to r1402,
formated the HDD (this is asked after downgrading, because it was formated in the pc as one partion.
so cleared all four partitions made only one then formated it).
still nothing in sysinfo 1TB disk is seen but 0 freespace and no partition found in browser under HDD.
but extensions where running again as these where not in r2160 after formating the drive there in previous attemds.
then I did a manually upgrade to r2160 as described in this topic by Chris and by Eugene earlier.
this did the job.
checked the extensions and I had to run them, this worked also.
(I was unable to upgrade the extensions as described earlier?)
in browser checked the HDD and now there was a map called "BT".
so everything okay again.
as I`m writhing this I`m copying back my files to the disk using the USB connection with my PC.
So as far as concluded after this firmware it`s not possible to downgrade because the internal harddrive then is not accesible by the playon anymore.
If I did anything wrong please give me feedback because I would not know what.
But for starters upgrading to this knew firmware r2160 was not a problem at all,
I just downgraded it because I wanted to check if there was less quality in dvd movies.
that I checked and there`s no loss in quality, better it`s an improvement.
advice is to manually upgrade, why simply because Eugene recommends it.
But for me and also others the normal way was no problem as well.
then one last point also I was not possible to acces internet radio anymore with this firmware.
This i copied out of another topic (New RC Firmware PV73100 v7.06.r2160 thread)because it`s easier then typing it again
