Has anyone been able to get Android Pay working on a completly stock D800? Even after restoring to 20c via .tot file and upgrading to lollipop Android Pay still is giving me the unable to verify you device message.

LG G2 (D800) KK->CloudyG2 3.3

Hello all,
I have had lots of troubles with my G2 but i just finished flashing 4.4.2(20c) onto my D800. I would like to go to CloudyG2 3.3
I have root, TWRP, SuperSu, all that good stuff. However when i tried to flash it via twrp, i got a boot error. I read somewhere that i need to use the KK bootloader so i went and downloaded http://forum.xda-developers.com/lg-g...kk-lp-t3104380, flashed it before Cloudy and then I got the same error. I just put stock back on my phone and I am currently downloading ROM-d80030b-stripped-v1.1-blastagator.zip from http://blastagator.ddns.net/rom.php. I think im going to flash this and try it all again...

OR

am I doing something completely wrong? Any input would be appreciated. Thanks!
