First download the sysupgrade image for your device to /tmp.
Then perform the sysupgrade -F -v /tmp/*.bin command.

What is the name of the device and hardware version?

23

i did upload the image by winscp to the tmp folder before updating.

this is my router

I see this: sysupgrade successful in your log.

Did you use this image? http://downloads.openwrt.org/releases/19.07.4/targets/ramips/mt7621/openwrt-19.07.4-ramips-mt7621-xiaomi_mir3p-squashfs-sysupgrade.bin

25

yes, i did

26

Did you reboot since the sysupgrade?

27

ah sh#t, i was using the wrong kernel all the time, found a old file in my backup which was unavailible in the r3p openwrt page, after i flash it, i could restore back to stock firmware, so now it will be easy to go back to openwrt..

thanks alot for your help, i own you one...

Then mark this thread as solved.
