I tryed to installed OpenWrt but I took the wrong firmware (I took the Gigabit version instead of the 100M version) after flashing I bricked it... I try te recover it with Xiaomi Mi Router 4A Gigabit Edition (R4AG/R4A Gigabit) -- fully supported and flashable with OpenWRTInvasion - #678 by Zorro but the "test.bin" does not look like correct. How can I restore my router as it was before? can I use TinyPXE.zip to install a working firmware? Where can I download a working firmware?
if it is possible to fix it with an spi connection I have the material to do but I don't know how to plug the wires....
Thank you in advance.
