Ok. I have successfully flash based on this tutorial but there is no 5GHz wlan. I want to go back to stock firmware with this command:
root@OpenWrt:/tmp# sysupgrade -v -n /tmp/oem-sysupgrade.bin -F
but i have this error:
root@OpenWrt:/tmp# sysupgrade -v -n /tmp/oem-sysupgrade.bin -F
Thu Oct 13 20:44:12 UTC 2022 upgrade: Image metadata not present
Thu Oct 13 20:44:12 UTC 2022 upgrade: Use sysupgrade -F to override this check when downgrading or flashing to vendor firmware
Image check failed.
I have prepared the image with:
./tplink-safeloader -z re200v3_eu-up-ver1-1-0-P1\[20190731-rel41250\].bin -o oem-sysupgrade.bin
What's wrong with 5GHz?
Thank you for your patience.
