I've got a stock LG Velvet 5G from T-Mobile that I'm turning in for an insurance claim (I was sent an LG V60 in exchange). I'm trying to take a full backup and then wiping it before I mail it out to them.
I've not been keeping up with current events in the tech industry, but upon loading up ADB I'm seeing a deprecation warning, which I've just caught back up about moments ago. I'm aware ADB backup doesn't necessarily take a full backup (exclusions from manifest, xml paths, etc)., but I'm unsure what other method would be considered more all-inclusive at this point. Furthermore, upon glancing at the XDA forum for this device (here), it seems that although a method to obtain root is available, the OP declares "backups are broken" and does not further specify any details. I'm unsure if this means that the best I can do is take the ADB backup and hope it gets everything (and manually backup what I can think of — off the top of my head — that doesn't get captured, like 2FA tokens, etc), but will obtaining root/su actually help or not in my specific situation?
