Dir 878 and the configuration restarting after reboot

Hello, i have a problem that my d-link DIR-878 resets after reboot, its propably because the 16MB flash, but is there any solution?

Please post output of

ubus call system board
sysupgrade -l

Start with sysupgrade to 23.05.5

but there is no 23.05.5 version for this exact model, so i download other image or what?

oh wait i found it there

(https://downloads.openwrt.org/releases/23.05.5/targets/ramips/mt7621/)

Its found here too.
https://firmware-selector.openwrt.org/?version=23.05.5&target=ramips%2Fmt7621&id=dlink_dir-878-r1

looks like somehow you flashed kernel in place of full openwrt.
It is easily fixable.

as i mentioned in my last post, i am new here, i flashed the openwrt image with failsafe UI, i don't have any other knowlegde of how to do it except that

and now i have the 23.05.5 and what to do now?

touch a file in your home directory, reboot and check it is still there.

touch whatever
reboot
... 5min later ssh
ls -l

Wait, did you actually install 23.05.5 sysupgrade or you need help with that file?

i installed it (with web ui, idk if it is wrong or something, if yes, sorry)

You re-gained config persistence, your router is good as new, change hostname in system section, reboot again, if new name applies you are all set up.

thank you (why is it so stupid lol)

For web-only system upgrades install luci-app-attendedsysupgrade

i meant that the solution is stupidly easy, just create the file, like whaaaat? nothing in my linux career was that easy

File persistence means /overlay with config files is preserved through reboot.
It is not a fix, just diagnostic without sacrificing rich configurations you made.
