is it possible for you to upload a 2011.06 custom firmware without android market already installed? Maybe we could test different android market versions. If there is a correct market version for this device out there, this may be the fastest way to find it.
It is very simple to build one without the market. I'm afraid though that your alternative search for a market application will not be successfull. I have already tried over more than 25 different versions, also from other tablets and phones.
Secondly: market can't be installed the normal way like any other application. Some programmers are able to break this behavior, like in the Gapps4Archos or the gAppsInstaller. These don't work on the A7 though. If you can't break it, you have to install is as a system application like I did for the A7HTV2 as the system partition is read only. Himself solved this in his yar roms by making the system partition read-write. I don't want to go that way yet. It's really an 2.1 issue occuring on many, many other devices.
Note though that I don't say it isn't possible. I simply can't make it work and by now I think I know a little about it. Off course I hope someone better proofs that I'm wrong. (Please proof that I'm wrong).
I added the 2011.06_NOmarket rom. Check the first post of this thread. I hope you are succesful, then we all benefit.
About the market, its like the moment i start using it, it starts giving feeback for another user's downloads, what leads me to think that some of your? user data is still in one of the (read only?) files, but of course it's just a hunch.
Some apps managed to get downloaded anyway, just to discover the 'downside' of open source: incompatibility...
There is no user data from me or any other builder/user inside the rom. I use a script that always starts from a clean update.img (now the 1.0.1 version) and copy the applications and other stuff in. It's not even possible to add user data the way the Archos tablets are configured. The data partition (NOT the 6.5-8 GB internal storage memory) is created on flashing. It would require me to really, purposely, change the way it boots to be able to add user data afterwards
. It can't be added by adding beforehand to the update.img.
And yes: not every application in the market runs on the A7HT. What's more: not even all applications in the Archos appslib runs on the A7HT or A8HT. They are for the line of the 34/43/70/101 IT devices.
