I hope this is a simple question for those that have done it. From reading the Factory install guide I was sure that it is the kernel image named below that I'm suppose to use.
However someone reported on r/openwrt that this exact file bricked their X5000R and it's the sysupgrade download that should be used so now I'm confused. Furthermore there are two sysupgrade.bin with different checksums from the following two links. Which exact download am I suppose to use with the factory firmware?
İ think you need sysupgrade. Because in x5000r device page only available sysupgrade. And kernel file is testing purposes. İf you will install kernel file after reboot it will get erased. Because its for one time use.
Thank you all for the pointers. The flashing went well. To get both 2.4G and 5G radio working I did have to ssh in and edit /etc/config/wireless by follow this post
Hopefully this will help other Totolink X5000R users out if they run into the same problem.
