After installing the ROM and reset all seems to be ok.
I've installed several programs and the my Polaris freezed so I had to do a re-boot. After that - it took a very long time for booting - I came to the setup-screen (calibrating the screen) and after that all my installed programs were gone... There was no owner-information also. I've tried 28008 several times but I couldn't use it because of these problems.
After that I've tried 23053 - the same.
Now I'm back to 3L3 6.1
No problems until now but I'd like to have your 28008 on my Polaris.
