Hello all,
I bought a AX3200 (RB01) in a local market (Perú) and followed the instructions from https://github.com/mikeeq/xiaomi_ax3200_openwrt ,
I soldered the pins to connect through USB-TTL (CP2102) from a laptop with Ubuntu 22.04.
At some moment I could boot an OpenWrt basic (kernel) firmware but couldn't load the sysupgrade, when I rebooted (I suspect) I bricked my router, this is so?
I tried powering up with the reset button pressed or pressed for a very long time with the same boot sequence.
I also tried using TinyPxe with factory.bin but the boot process didn't change at all.

(I bought a second Xiaomi Router but the Chinese version (AX6S RB03) from Aliexpress and I could install OpenWrt without issues, but I need a second to make a mesh)
