Hello,
I just bought a Keenetic KN-1613, downloaded the factory image from https://firmware-selector.openwrt.org/?version=23.05.5&target=ramips%2Fmt76x8&id=keenetic_kn-1613 (saved it as factory.bin), went through its setup wizard, but when I try to upload the firmware through its GUI it returns the attached error
As it offers downloading its current firmware, I did that too, and renamed the factory image to the name of the downloaded firmware, but it failed with the same message.
I read through the https://openwrt.org/docs/guide-user/installation/generic.flashing page, but everything beyond method 1 is a bit cryptic. For the bootloader, how can I figure out its IP? (It would be great if I could use the GUI. 
)
Could someone provide more instructions on how to install OpenWrt on this router? (It offer telnet.)
