[General Questions and Answers] Ghoymakh:
I see.

Looks like whoever made the PBJ40 (aka Grid10) also sold some of its stock to other companies, and since the 'other companies' don't have a dev. team to compensate for the lack of drivers for the Tegra2 (I heard they're going to release the drivers in some 2 months), they had to sell it with Android 2.1 (froyo) on it, with lots of problems like screen responsiveness, poor power management, and the like.

I'm also guessing that you do not have Market, Talk or GMail on your tablet... or at least, you didn't have it at first (doesn't take much skill to install them... the tablet comes rooted).

I'm also guessing you have a serious gestures issue, am I right?

Do you have the 40 pin USB cable? (or did yours come with a regular female USB port??)

... I might be of assistance, if you're able to make your dev skills work in your favor.

So help me help you...

The only way this will work, is if you're able to reverse engineer the GridOS to:

1) Extract the programming that's responsible for the gestures so we can install it on any other device (like your PBJ40, which doesn't have gesture support as advanced as the Grid10), to make the device easier to use.

2) Override the sign-up screen for the GridOS. In case you do not yet know, once you boot GridOS for the first time, you're taken to a setup page (much like the setup page of Windows) where you register yourself on the FusionGarage server (people who made the GridOS) to gain access to the tablet... for some time now, the FusionGarage server has been down, and since the company recently went under, there's no way the server will be fixed ever again, so even with linux kernel 2.3 (aka android gingerbread... without the market) you can't have any kind of access to the tablet, because you'd be unable to proceed form the sign-up page forward! So if you can find a way to over-ride the sign-up page or 'delete' it from the equation altogether, we both win!

So: I can provide you with GridOS kernel version 2.3 (not android... GridOS! It's basically the same, it just doesn't have the Market, and its UI is different... still very nice... I like it).

So... you can't install GridOS on your Froyo tablet (just yet), even if you had the 2.3 GridOS at your disposal, because you'd be stuck there.

So the question remains:

- Can you reverse engineer a linux OS that is android based (but not truly android) to extract from it the gestures program so you can make your PBJ40 more responsive?

- Can you somehow customize GridOS to delete the whole signup page issue?

Both of these things will help me a lot... but only the gestures-solution will be of help to you, unless you have the USB cable for the tablet.

If you PBJ40 is not a regular Grid10, I'd like to see it from all angles + a picture of its cables and chargers... if possible, please upload them to this thread.

For now, to make your life easier, install the program called zMooth from the Market. Its gesture responsiveness will be much better than the 2.1 Froyo version your tablet is now running.

"swipe left to go back, swipe right for menu, gesture a up-arrow(^) for home"

Look at the screenshots to better understand.

While setting up the program sensitivity level, keep in mind that the lower the level, the more sensitive (it's in fine print).

... let me know what you get!

PS: It might also be of help if you can somehow get the gesture program from ICS kernel and adopt it to PBJ40!
