Issues going from d80020c to lollipop??

I am currently on d80020c I am rooted. I have latest TWRP installed. I tried to goto the resurrection lollipop but was getting a compatible error.

I was told to load new bootstrap then Rom.

I got the bootstack installed and then got compatible error again and it was then bricked with qsusb.

Am I missing something?

I just want lollipop and cannot get OTA updates unfortunately.

Thanks!
