This is not my router model, I have Xiaomi Mi Router 4, 4A is a different model. Will it work for my model as well? If yes are you talking about this link - Xiaomi Mi Router 4A Gigabit Edition (R4AG/R4A Gigabit) -- fully supported and flashable with OpenWRTInvasion - #678 by Zorro ? The program used is running on windows, I don't have a windows machine, is there no way to do this in Linux?
