Sometimes it just gets stuck for some seconds.
Genereally its really slow.
I don't think there is anything more that can be done
Oh, I'm sure there is! This tablet runs very well on CROMBi-KK if it is installed properly.
If you are up to taking another swing at it post:
bootloader and version
recovery and version
what options you chose during installation
what you wiped and how before installing the rom
I'm confident we can get you to smooth sailing before long
