I keep trying to UPDATE my Sam Gal S9 with a security patch from Nov 2019 but it shuts off and stays off instead of rebooting then says Firmware update failed when I get it back up. Samsung..no help...Best Buy...no help...Verizon...No help. Google and YouTube...no help. Was told needed to be on a strong direct wifi ( as I am using an Xfinity hotspot), even though I've never had a problem with my previous devices. Didn't help when I was directly connected to a residential wifi. Tried to do it through Smart Switch..no go. Tried to do a sideload from the update that I downloaded from Samsung...no go. The only thing I haven't tried is a Factory Reset. Is this a thing someone can help with? I'm not worried about this patch but if I'm going to have this issue with a major update Ima be upset. Thanx in advance.
