[Q] Samsung Galaxy Tab 2 10.1 Bootloop topic

Hi. Please help. I have been running CM10.1 on my rooted tablet and I decided to try CM11. I don't know what I have done but CM11 did not work so I tried to go back to CM10.1, and that just gets stuck on the boot screen. I have tried several different Roms and they all get stuck on the boot screen. The only Rom that will work is CM9.1? I don't know what I could have done to cause this. I am running Philz Touch 6.12.8. Any help would be greatly appreciated.
Thanks
