Does anyone running firmware 4.4.1 have a fully functioning system?

Seems everyone who is having issues is locked on version 4.4.1 and unable to update
is anyone on this version not having any issues?

Also, question to people with completely functional systems. Can you ever recall being on version 4.4.1?

Trying to dechipher whether we (4.4.1 users) are possibly a victim of different (and perhaps faulty) chipset that only ran firmware version 4.4.1
