The keyboard backlight works for me. I would wipe data, clear cache and dalvik cache, flash AOSP21, reboot. Then go back into recovery, wipe cache and dalvik cache and then flash gapps. See if that works. There is an app on the market, can't recall the name at the moment, that blocks ads quite well.
This is not good advice.
When installing a rom you ALWAYS wipe data, unless told otherwise.
1. wipe data/cache/dalvik
2. flash aosp21
3. flash gapps
4. reboot
