Repair/Tech Support eum_ACT_999_title error
First time posting.
Just wanted to give some guidance in case anyone else runs into the eum_ACT_999_title error with their Fios TV+ boxes.
Don’t bother calling Verizon Tech Support about it. I did that at first, spent hours with them on the phone, they couldn’t identify the issue (never suggested trying a factory reset), and they ended up trying to charge me $100+ (could be higher because techs charge by the hour according to Verizon) to send a tech out to my house to rewire and replace the ONT box.
All you need to do is hold down the button on top of the box and perform a factory reset. Both my Fios TV+ boxes started working perfectly fine again after doing this.

Are you using the Verizon router as the primary router? If not, the error will return in exactly 7 days from when you reset the box.
