A few months ago made a custom image with snapshot(r11167-273a6cb562) image builder by mistake. There is some sort of instability. Periodically the roter (Xiaomi Mi WiFi mini) stops to respond and no wifi or switch traffic can pass. Rebooting from power restores the functionality of the unit. When I try to flash the latest stable release I get the following:
sysupgrade -v /tmp/up.bin
Device xiaomi,miwifi-mini not supported by this image
Supported devices: miwifi-mini
Image check failed.
Is this just a minor string change, or there is more general changes and it is not safe to force downgrade?
It may be a minor string change related to being more specific about board names. In some cases a new board name is used to "protect against" an upgrade/downgrade that, for example, changes partitioning.
$ git log --pretty=oneline target/linux/ramips/dts/mt7620a_xiaomi_miwifi-mini.dts

What kind of instability are you seeing? What other packages have you installed, if any?
Althou I tend to stop unused services(acme, colectd, radicale, tinyproxy, sshd, samba) if I have the time
Instability. Router stops to respond and forweard traffic in any direction. Also it is inaccessible via ssh.
Hapens in about a week time period.
Could be somethig related to wifi. From about 2 weeks i have only 2.4GHz SSID without password. And before someone starts yealing at me, Iyes I KNOW the risks. That's why I want to upgrade/downgrade.
I'm also having that "Image check failed." message downgrading a TP-Link WDR3600 from OpenWrt 19.07 ath79 to OpenWrt 18.06 ar71xx.
Maybe it could be due to the architecture change?
You have to force upgrade to change from ath79 to ar71xx or vise versa. But that belongs in a different thread from this one which is about a MT7620 based router.
