Hi to all and sorry for my english.

My question its, How downgrade my memo pad hd 7?, in the last update, my bluetooth fail in my car , i want to downgrade android version.
I download the kernel core, from the asus web page, but i dont know if with this zip i can reinstall android , or if i need rename de file.

If i need rename the file, what name i put?.
