Dear @eduardo010174
thanks for compiling and sharing.
But ... I see that the port assignment is still wrong 
It hasn't changed in your last three builds.
ok i try now with --hard option
its have 3 options of reset.
i don't think what its best

I am testing 
It will take a while. But this one looks good. I will write more as soon as I have the results.

Dear @eduardo010174,
your last build is excellent! 
I have figured out that I have to reset the firmware and to reconfigure all settings, because the original Nano-build configuration file which I was reusing (with the wrong port assignments) had led to a bug.
After reconfiguring all settings it works perfectly.
I have checked the port assignments and see that those are shown correctly under "Switch" settings.
Furthermore I did some extensive WiFi testings and see that everything works correctly.
Not a single disconnection or signal loss.
Everything works like in the stock firmware.
The datarate reaches the maximum possible of my ISP.
The jitter in WiFi is higher than with the R2100, which I am using as my home router, but at the same level as the stock Xiaomi firmware with the Mi-3C.
Furthermore the WiFi range test shows that in 10 meters distance with two walls in between I still have 70% of maximum datarate, but the jitter goes up. Still not critical and not worse than stock firmware.
At 15 meters distance with three walls in between it does still connect to my smartphone but the datarate is very low. But that is exactly the configuration where also the Xiaomi stock firmware reaches with its suspect "wall penetration" feature its limit.
Final conclusion: Excellent work!
Please continue to make the naming adaptions to Mi-3C.
And if God wills, we will be able to see the pull request soon
Kind regards to Portugal

One Issue that I found with wireless is that after long hours of connection, there is no internet access on wifi and at the same time I am unable to access OpenWrt Page through wifi, I have to disconnect and reconnect. but on ethernet, it works fine. I guess it must have something to do with DHCP lease expiration?
hey guys, does anybody have the stock bootloader of the mi router 3c.
I want to go back to stock rom is there any guide to go back
need the original mtd backup
I have the dump file with stock rom. You can flash it by breed programmers firmware

thanks i will try it and yes i have breed installed
is this a full backup or I just need to flash the rom part in breed bootloader
Dear @Kale
the file shared by @anjmis04 is a full flash file.
Flashing only the stock bootloader does not provide you the option to flash a stock firmware.
I had tested this intesively but it doesn't work even though it provides a web interface for flashing the stock firmware. But it doesn't work.
The only way to return to stock is to flash a full flash file.
Either by BREED, or via SPI flasher.
In case you want to flash only the stock bootloader then take the file from @anjmis04 and create a bootloader.img file out of it by cutting off everything which comes after the bootloader in a HEX editor.
But as mentioned this will lead you to a situation, by which you cannot flash the stock firmware and also not BREED anymore.
The result is a brick, which can only be resolved by SPI flasher.
