I was not sure if I did something wrong or something.
But yeah. Normally i do i over cable but i did not have that option at the moment do to the only machines i own that there are on cable are consoles.
But i had i fall back option.
But i have been reading a bit more up on my now "error" and it tells me that i can delete 2 files and make a workaround that way.
My only problem is that my settings (just tested with 19.7.10) did not follow over and i therefore lost most of my configuration anyway as it looks now.
Sorry to hear that. In that settings case you could just force flash while wiping settings.
You can indeed just wipe /etc/config/network and be fine with it; --force will still be required though. At that point you might as well just SSH in and sysupgrade manually with -F -n.
Reboot to your working alternate partition (19.07.7) and make a backup - System/Backup Flash/Firmware/Generate Archive. This will create a backup of all your current configs.
Flash 21.02.3 (Force, Do Not Keep Settings). On boot, you'll have default network on 192.168.1.0/24. Reconcile /etc/config/network against your backup /etc/config/network.
Then you update opkg and add your additional packages. Most of these can be migrated as is directly from your backup.
Unfortunately yes, but next upgrade you should be able to save settings. Check this link for a couple of options/scripts that you can run on your 19.07.7 partition to identify what packages got added after /rom was built.
