Sorry to put this on a separated thread, but now that i physically checked on the device, i could see my Xiaomi Router 4A Gigabite Edition is carrying a Winbond flash chip.
Couldn't see the model number because i just peeped through the vent holes in the back with a flashlight and a magnifying glass.
My final question is: Is it safe to install OpenWrt on this one or it is one of the troubling flash chips?
