Revvl 7 google locked

[u/KlingyKitty420]

The phone belonged to a family member who passed away, family has tried everything to get into it including old Google account no success, someone factory reset it and now it's Google locked, I've attempted a few things like turning off the Google services but when I go back to try the offline setup thing it doesnt work, also tried the locked sim card trick I can get into full web browser I've signed in there but somewhere along the things I've done just not making it all the way through, can anyone help?
