Hey everyone, so I've been using my AX3000T Router (RD03) for like 3 months that i flashed with a snapshot build and it has the uboot layout with recovery mode. Today I decided to upgrade it, so I downloaded the sysupgrade.ubi file for 20.05.5 and luci said that it was not the same model. so I got the uboot-squashfs-sysupgrade.itb and it went through. But now the router stays on a steady orange light and I'm scared to unplug it but it has been at least 2 hrs since I flashed the image. What can I do?
Do you have an ESMT or Winbond NAND chip on your AX3000T RD03?
- You can find the chip name here.
This post clarifies details for different NAND chips in the AX3000T and their support by OpenWrt firmware.
Just looked, sadly its a winbond chip
Am I screwed? or is there a way to fix this? I thought that the 23.05.5 version already had the fix but I guess not.. should've checked
OpenWrt U-Boot? Maybe someone can suggest more, as I'm not familiar with the specifics of the recovery on the custom bootloader.
Anyway, see https://openwrt.org/inbox/toh/xiaomi/ax3000t#debricking

Yes, OpenWrt U-Boot, sorry for not clarifying. I tried to do TFTP unbricking, but I can't ping or do anything to the router, even when I assigned my windows PC an IP ( i set my ip to 192.168.1.10, subnet mask to 255.255.255.0 and gateway to 192.168.1.1) and still couldnt do anything, tftpd64 was stuck on block #0 and the built in tftp in windows just said "Connect request failed"
I just unplugged it and plugged it again, i think its dead. no blinking, just steady orange from the start
No, it "just" soft-brick 
.
You need UART adapter to fix it.

One of the examples of a successful story for recovery of a router with a custom bootloader:
thanks for the info, I'll probably try to unbrick it but Ill have a lot to learn
