[G Tablet General] theroblog.com:
Might work for other ROMs as well, don't know why it wouldn't.

EDIT: This might help to fix My Apps. After installing some apps, the rest were populated.

EDIT: ro.product.device=olympus added. This gives you access to Tegra 2 games as well as the broadest market fix I've seen yet!

I've been putting <boolean name="local_db_sync_required" value="true" /> in /data/data/com.android.vending/shared_prefs/vending_preferences.xml from time to time. Seems to maybe take an install of an app to catch or something. Still a bit voodoo chicken ceremony type of affair.

This is an edited build.prop from the VeganTab 5.1.1 install. Some changes I got from a thread on fixing 2.2 on the HTC Desire.

I did it because some of the entries just didn't make sense, so I combined some stuff, and made a few semi-educated guesses.

And yes, I'll take donations. I'm passing some donations around myself. :) A quarter or 50 cents here and there would be thrilling. :)

STD Disclaimer: Don't blame me if it breaks stuff, backup your old one first.

Let me tell the wife I at least made a few bucks.

I'm working on some other stuff, so hope to have a few tidbits here and there.

I'm on the trail of being able to get your device recognized by the web google market and being able to install apps from your web browser. I can replicate it, but it's a bit more technical and an either or proposition, long story.

Shameless plug: I bought an extra gTab off woot and it's for sale in Houston, still sealed in the box.

There shouldn't be much 2.2 Froyo stuff that ISN'T visible. Everything I wanted to see or someone asked me to check for was visible, although I didn't try to install everything, but I think it'd all be fine.
