Bricked ax3000T need help please

Installing and Using OpenWrt
1

Hi everyone!

I've just bought an AX3000T to install it, learn about openwrt and upgrade my network knowledges, but I miss something at the very end of the installation procedure and it final reboot it just went brick.

I've bought an usb ttl, solder the pin on the keyboard, plug it and I'm able to see what's going on at the router start with putty;

I tried various solution, with miwifirepair doesn't work, the C0A81F02.img stuff saw here: Xiaomi ax3600 bricked - #112 by sqrwv it doesn't work, TFTP64 with tftpboot command; it doesn't work neither it says:

"Using ethernet@15100000 device

Load address: 0x46000000

it loop forever but don't boot it anyway.

So here I am, I was wondering a solution to just upload an openwrt snapshot to the router nand and then flash it or boot it but I don't figure out how to ( remember I'm a noob and still learning...)

Thanks for advance to any kind person that would help me....

This device is very tricky to be used as a newbie.
I suppose you followed the instructions from the device page. Which step did you fail to follow?

This is for a different device, just to make sure you are not using the same binaries.
There is also the procedure to go back to stock firmware from U-boot.

Hi @trendy!

Yeah That's the tutorial I've follow, I think I miss the very last step when it says flash stock image from back up.

I rebooted and the device stays on blue led, the rescue mode with the pin before power up doesn't work anymore.

I also try the method from ax3600t with the ax3000t stock firmware because I'm despairing...

Thanks for the u-boot procédure, but that's the problem. How to upload the recovery file from the server (my pc with putty for example) to the router nand ? I can't get ssh access, with winSCP it can't connect so... How?

I saw there a member (@Volenski )who was in same situation, same router, same problem (probably because of the same openwrt file finaly) and he says he solve the problem with tiny PXE :

I don't know how to use it so I'll give a try and see.

Do you have a tftp server running on your pc? It is unclear from your posts

The openwrt bin file needs to be available by tftp
