Default [Q] Why can't I seem to take Sprint OTA?

I've tried to take the sprint OTA several times now. I'm normally rooted and de-bloated. But I've tried unrooting and un-de-bloating my phone, but the update always seems to fail. It seems to start flashing then suddenly reboots and I'm back to normal, but no update. At this point am I going to have to manually flash my updates?
