Haha welll...im stock and put both files on my sd card. Powered off, held down both volume buttons, then selected recovery, then android logo with red triangle warning came up and then you hit both volume keys again. then i chose install from external card....and i chose the 6.7mb one which i hope was the right one...
then it installed and rebooted. then when it powered up, it came with that little black box "android is upgrading" and showed the apps getting updated. I was scared at this point. thought maybe it was wiping it or something. then it finished and everything is still there! so im happy by now.
i was nervous whether or not it worked, so i went to system settings and checked out the about phone. sure enough .214 build date 6-29! Thats how you do it stock baby!
I feel so accomplished!
