Hi,
I have installed Version OpenWrt 19.07-SNAPSHOT and want to update to 21.02.1.
I know that I cannot save my settings, but that would not be a problem. It is described that update should be done like a complete firmware update. The link seems the same for sysgrade and full update.
Can I do it via Lucy and ignore the warnings or should I do it somehow via ssh?
For completeness: here are my commands started from ssh with the error message at the end:
root@OpenWrt:~# curl -L https://downloads.openwrt.org/releases/21.02.1/targets/r
amips/mt7621/openwrt-21.02.1-ramips-mt7621-xiaomi_mi-router-4a-gigabit-squashfs-
sysupgrade.bin --output firmware.bin

root@OpenWrt:~# mtd -e OS1 -r write firmware.bin OS1
Could not open mtd device: OS1
Can't open device for writing!
and that ist the "error" from sysupgrade:
root@OpenWrt:/tmp# sysupgrade firmware.bin
Device xiaomi,mir3g-v2 not supported by this image
Supported devices: xiaomi,mi-router-4a-gigabit - Image version mismatch: image 1.1, device 1.0. Please wipe config during upgrade (force required) or reinstall. Reason: Config cannot be migrated from swconfig to DSA
Image check failed.
root@OpenWrt:/tmp#
and a similar message occurs via luci firmware upgrade. Is "force upgrade" the correct way?
fwiw, you must have installed a custom 19.07 snapshot build, because there was no such official snapshot build for the mir3gv2 (or almost identical R4AG)
It worked. Thanks.
Yes, during my first installation I followed the suggestions in a Blog that OpenWrt works on this device with that specific custom build.
