As I understand that is to tell the Novo7A to pretend to be another tablet?
Any recommendation on what string to edit, and to what?
Simple make sure your tab is rooted.
Then get a program called root explorer.
Go to System>Apps>Build.Prop
Press and Hold and select Copy
Press the back key twice.
Go to either SDcard or Ext mount
Paste build.prop
Connect your tab to the computer and press Turn on USB
Download this
http://notepad-plus-plus.org/download/v5.9.6.1.html
and Right Click and press "edit with Notepad ++"
Look for these lines
ro.product.model=DROID2 GLOBAL
ro.product.brand=verizon
ro.product.locale.language=en
ro.product.locale.region=SG
ro.build.description=cdma_droid2we-user 2.2 S273 2.4.29 ota-rel-keys,release-keys
ro.build.fingerprint=verizon/droid2we_vzw/cdma_droid2we/droid2we:2.2/S273/2.4.29:user/ota-rel-keys,release-keys
Change it as it is.
Save Build.prop
Go back to Root Explorer and Copy the newly editted build.prop back to the original location
When prompted to overwrite. Do so.
Go to Settings>Applications>Market and Clear cache
Restart Tablet.
Once you start back you will have a new system.
Check your market capability by searching gameloft games.
They Should be compatible now.
Good Luck!
