Good morning, I have a Xiaomi AX9000 router that I have bricked. I am trying to unbrick it using UART, PuTTY, and TFTPD.
I flashed a .bin file (version 3.0.40), but the router keeps getting stuck in a boot loop. According to ChatGPT, it could be an issue with the NAND partitions.
Could someone please help me unbrick it? Thank you very much.

Oye, se debe escribir en traducis a Ingles. Sin usar chadgpt.
If you have bricked device with OEM firmware upgrades ask their support?
I cant ask Xiaomi , I have lost my guarantee
Via serial can you press any key to break the boot loop and enter commands ? If so I guess just follow this:
Confirming here, TFTPBOOT method works, I am on latest snapshot also with ax9000 international. With this, you dont even need to build your own image.
What I did, based on @Matezon 's description:
Setup TinyPXE server at 192.168.1.100 (desktop), serving the openwrt-ipq807x-generic-xiaomi_ax9000-initramfs-uImage.itb (latest from Robi's repo)
UART connected, boot into u-boot
setenv ipaddr 192.168.1.1
setenv serverip 192.168.1.100
tftpboot 0x44000000 openwrt-ipq807x-generic-xiaomi_ax9000-initra…

Here is the outline of debricking simpler devices YMMV

Hey there, guys. The title is self-explanatory, but here it is
my router was sh… ipped with the 3.2.30 firmware, and it was the English/global version. I tried to flash the latest OpenWrt, albeit for the v2 version, using the exploit.
But I guess my router was the v1 kind. So it never booted up again
orange light staying on.
It does go to the safe mod with a blinking orange light and when using the Tinypxe the light blinks fast and turns purple, but it stays that way and won't flash all the way through
so what are my options now ? Is it fixable ? What can I do ?
Thanks for the help in advance.
