Sorry for the delay. I've linked the OTA (original, no edits). I tried converting it to something that can be flashed with CWM from a couple tutorials I found online (but i hardly tried honestly), I tried sideloading it but no go (can anyone else mount sdcard or external sdcard? I can't).
But I briefly looked at the contents and it looks like what Spec2nirvash had said, mostly a google apk update but also some updates to a number of libs (libraries?).
