Unhappy Tablet stops auto rotate

Hi,

I have a Blaupunkt Endeavour 1010 tablet and after installing busybux the screen doen't rotate anymore. I flashed the original oem firmware with android 4.2.2 and tried an other busybox version, but there is the same problem. Every time I flash a original rom all is working fine (android, root, apps, ...) but after installing busybox I cant rotate the screen.

Can somebody imagine whats the problem could be?
