PLEASE HELP ME BECAUSE I HAVE SCREWED MY TABLET UP!!!!

I have a device "Asus Transformer Pad TF300T" running on Cyanogenmod CM12.1 Snapshot build (Custom ROM).

For some reason my Google account was not working properly on my tablet, nor could I add an account to be tablet.

When I did a factory reset on my tablet, after my tablet restarted, a screen named "TeamWin" showed up on my tablet, it was stuck to that screen and would flash black and the same screen and it did this on a loop.

My question is do you know how do I recover from such problem, please let me know as I would like to fix and use my tablet again, thank you :)
