Hey well I hope there is someone that can make a custom rom for this tablet...here is some information ive been able to find out... From Rooting and Installing market:
TO Root Tablet..
After Installing "jdk-6u25-windows-i586" and "android-sdk_r11-windows" and "ADB_usb_driver"
Connect your device via USB.
Now, hold the Windows Key and press R. Type cmd in the box and press Enter.
In the Command window, type
and hit enter. Now type
and hit enter. Now here is where you will begin rooting the device. Type the following
adb devices "I did this to make sure the device was listed"
and hit enter. you should now have a # sign.
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
hit enter, then type
cat /system/bin/sh > /system/bin/su
hit enter, then type
chmod 4755 /system/bin/su
hit enter, now type
hit enter then finally type
and hit enter. Your device will reboot. When it comes back on it will be rooted!
To Install Market
The following list includes the exact google apps package I used, and the order in which the extracted apk's were installed...
google apps package : PM me if you want the link...xda says after 8 posts I can posts links
Only use hdpi package for CyanogenMod 6, otherwise the apk version will be wrong
and with this apps package, I extracted all of the apk's inside, and used "all" of them.
They were installed in the following order :
app 1=genie widget apk
app 2=google backup transport apk
app 3=google contacts sync adapter apk
app 4=google feedback apk
app 5=google partner setup apk
app 6=google services framework apk
app 7=google voice apk
app 8=kickback apk
app 9=market updater apk
app10=media uploader apk
app11=network location apk
app12=setup wizard apk......
note: setup wizard apk is needed for the log in scripts to google market, and google talk respectively..
app14=google talk apk
note: I believe google talk is the engine used for the market portal access....so you must install..
note: vending apk is installed last just prior to reboot of the cruz tablet...
this is the exact order of install from the above apps package I used....and I have 2 working cruz tablets with market access, google talk, and gmail.
Note: gmail apk is not included in the above apps package, and is downloaded from the market once it's working.
Note: dont be worried about space for the apk's. After the flash card partitions made in the 2.2 firmware update, you should have nearly 425 megabytes of application space remaining for apps later on. And the total size for the apps package is only 18 meg.
To Reset Market:
Thing is, I've found that a number of apps that don't appear in the Market still install just fine. For example, I can't locate Maps in the market, but it works, as does the similarly invisible Dolphin HD. There are hacks for the Market that are used to allow QVGA phones to see items that aren't specifically tagged as QVGA-compatible, so there may well be similar hacks to allow us to see more. (It may or may not install, but at least we'd have the chance to try.)
Edit: found a note on the Web re: the Market. An Archos user found that if you follow these steps:
Go to Settings - Applications - Manage Applications - All tab;
Go to the "Market" app: "Clear Cache" then "Force Stop" DO NOT Clear data;
Go to the "Google Services Framework" app: "Clear data" then "Force Stop";
Reboot your machine;
Restart the Market application. It may force close for the first run, ignore it and restart it again.
