I was about to update for better notifications but I think Ill just install ATN..
I have null_08 or 7 (whichever is newer.) and I think the problem is tryin to update your Gears firmware when It has a custom ROM or root. You would have to flash the Original software V7 software THEN do the update. it wont update on these modded watches. \
It might be too late for some of you but I would recommend installing the previous version of the gearmanager.apk
and if your ROM'd then go for ATN (allthenotifications) - its just an apk for your phone. no gear adjustments. You might also have to wait for the Original firmware files to come out so you can flash back (ha) to the (future) stock system and upgrade after once your "legit"
