@ DaremoS - Thanks very VERY much for your links and uploads.
Feedback: I'm using Prestigio PMP3804B
On first boot screen is upside down in portrait mode, so I looked into local.prop which took a little while to figure out (in fact I still haven't exactly understood which is which axis) but I've got 3 screen orientations working (4th option, landscape with page up/down buttons on bottom edge) doesn't work right now (screen remains where it was last) but 3 out of 4 is good enough for me. My values are 0,1,0,0 if anyone needs to try something. When I get time I'll continue testing values... I saw fun_ posted something about this and in his example he #'ed out the last two lines... didn't work for me but I didn't change the 1st two values during that try either. Correct me but a reboot is necessary... right?
MOST IMPORTANT: Screen calibration, accuracy and 'snappiness' are vastly improved! Yes the screen is resistive touch not capacitive like the costly tabs out there, but wow! What a difference this ROM makes.
Overall system speed is improved for sure.
I can't get USB to work. If I plug in USB cable, then select to copy files item on notification bar, screen changes briefly then closes with no message and returns to home screen.
EDIT: Installed Free Power Widget, which has a USB toggle. When I switched on USB via this control, I got ARCHOS7 and SD Card popping up as drives on my PC. Yeehaa
I installed Spare Parts from Market, so I know Market works, but 'My Apps' list is empty in Market. EDIT: did the Market fix from page 1 (FROYO v5, etc.) which seems to have fixed My Apps list. Realising now my Google Account won't sync (no email, cal or contacts exist
Installed LauncherPro - which works fine.
No CyanogenMod settings are working (FC on select)
CPUBoostLite won't run properly - seemed to add some speed if CPU set at just around 700MHz in FROYO v5 (I didn't want to push it too much), but in your GB 2.3.5 it shuts down all the time (also no error given).
OK... so... I'm not sure now whether to go ahead and install GAPPS and all my apps, but my feedback to you is that yes, this really is an improvement on screen calibration, overall performance and snappiness. Well done and thanks again for your efforts!
One small issue I'm having, but not only on this ROM - is sometimes the tablet won't turn on until I uses reset pin... anyone else suffering from this? It happens from auto screen off, when I press power button briefly (standby?) AND when I power off completely... but not consistently... and not always from one way... only now and then. Weird.
Would be absolutely fantastic to have this ROM included in the CM nightlies and to find someone willing and able to tweak a really nice kernel for us. Obviously also the Video playback would be key but the trade off for screen accuracy is compelling.
Last item - does anyone know how to make a complete image backup which can be restored? Haven't tried MyBackup Root or Titanium yet... but that's also because this is only the 2nd ROM I've tried from the out-of-the-box eclair.
FROYO v5 with this 2.3.5 RK2818 8.4" screen calibration would be very very good for everyday use.
This GB 2.3.5 ROM with Video, CyanogenMod functionality and Market/USB working 100% would be UNBELIEVABLY COOL
Thanks again. Anything you need from me i.t.o testing, logcats, etc. please ask.
