It's curious that going back to the old OS didn't fix the issue. (That's one of the things you say you tried, right? ... When you downgraded, it was to the very same old OS you had been using before with no problems?)
Maybe a wipe with JL_CMDER is the next step. I don't know, just wondering out loud.
What about doing a security wipe and also delete all third party applications, restore your data from a backup, and then add back the third-party stuff one at a time?
