I just opened up the router and look a look at the board but dun seem to be able to find the serial connecters. Can the experts here point me to it.

There is J252 socket (unsoldered). From left to right: 1: TX 2: GND 3: RX. You can attach 4-pin block connector to it without any solder.

To unbrick, try to set:

Code:

nvram set boot_wait=on
nvram set wait_time=30

and try to reflash via CFE WEB server

or, setup tftp server with address 192.168.1.2 on PC, put tomato.trx there, and do in CFE prompt:

Code:

flash -noheader 192.168.1.2:tomato.trx flash0.trx

Hi, I got a new Xiaomi router and tried the procedure to flash dd-wrt in the OP. It didn't work and went into a reboot cycle.
All I could access was the CFE web server during boot.
I tried to flash back to stock, which did not work either.
Then I got desperate and tried to flash the Tomato firmware posted by tsynik from the CFE web server.
Now I can't even get to the CFE web page.
The router powers on, front orange light is steady, then all LAN/WAN port lights come on and off, and repeat.

I ordered a UART-USB tool to try tsynik's diagram method above.

Is it totally bricked/hopeless? Thanks in advance for any help!

this dd-wrt build for xiaomi have bad mtd layout and may have issues.

it's better to flash custom CFE (so you can always restore your router in case of any failure) and Tomato firmware on it. More info and all binaries here.

I cannot download the Custom CFE for R1D by XVortex. He is great! I have used his CFE for EA6900 and solved the problem for this Linksys Router.

I hope that he or somebody can post the link or CFE file here.

Thank you very much.

It shows, but only in tomato GUI, not advanced tomato.

HDD temp is only in my ML 129 version.

Tried to flash the latest DD-WRT version (29th June one) posted in that thread

Ended with stable orange led on reboot which means the device is temporarily bricked

Can someone point me to a link where I can see how to disassemble the unit? I cannot seem to open the top part with the vents. Can see there are clip locks which hold it to the main unit but unable to unlock them

Would be helpful

Thanks in advance!

Not sure why you expect any replies here, the Xiaomi is not supported by "dd-wrt". The FritzBox is completely different it is an all in one solution with solid oem firmware. It's only flaw is the traditional crappy wireless/slow soc. Soc/radio wise it is always one or 2 generations behind.

If you are in need of a fritzbox, then it is unlikely that you find any dd-wrt router that suits your needs.
