Reapjack - How did you apply the update. Through the recovery or through a normal boot? I know inside that update there is an updater-script for doing a full update, includes mbr, kernel, system...etc. I am not sure how to trigger it though. Maybe thatís what the boot flag is for in the recovery.
I did finally take the risk and adjust my density in the build.prop file. Tried a few different settings. Default is 180. I am currently running at 160 but did try 200 and 220. Looks good but the display is still not as clear as my phone (HTC Incredible running MIUI). I know the screens are not really comparable, but Viewsonic has been designing and building monitors for years and this is the best screen they could put in this tablet.
Also did some digging around on the internet about the host cable. Found a few here and there but I can be rather impatient at times, so I decided to make my own. Chopped off the end of an old Motorola house charger, shaved off al the plastic around the end, de-soldered the wires and one resistor from the small board. Then dismantled a usb cable I had made for my original Xbox, soldered the cable to the mini usb end, shorted pin 4 to pin 5, plugged her in with a keyboard attached and it worked, first try. I did notice that the host mode is not real reliable. After the initial test I could not get it recognize keyboard again. Checked all solder points, tested from usb female end to mini usb, all tested good. Several reboots with cable plugged in, nothing changed. I knows to go into host mode, I can see it switching when i run dmesg. But it just doesn't know what it attached to cable.
