Xiaomi AX3000T silent update failure (?)

Installing and Using OpenWrt
1

I've tried to flash a new snapshot on my router and it seemed to run fine, but any attempts to edit configuration files failed, the router not saving any changes on reboot. Upon further inspecton, I've noticed there's no overlayfs. Running df -h shows only three tempfs...es mounted on /, /tmp and /dev. Did the update fail? How do I recover from this?

let's see some details here:

ubus call system board
mount
df -h

Okay, here's the output:

This is why:

You have the initramfs version running -- you need to run sysupgrade with the sysupgrade image (not the initramfs).

5

Thing is, the image I used is a sysupgrade image! "openwrt-mediatek-filogic-xiaomi_mi-router-ax3000t-ubootmod-squashfs-sysupgrade.itb"

6

What happens if you flash a release build?

7

Do I need to choose the sysupgrade image to do that?

8

Yes. Sysupgrade.

Cannot save config while running from ramdisk.

Connection to 192.168.1.1 closed.

It then boots right back up, running the same snapshot as before. Odd.

You’re using the openwrt uboot images, do you have the openwrt uboot installed?

11

I certainly did before I've attempted to update the firmware. How do I check if it's still there?

12

I figure I'm supposed to flash some other image, correct? If my rootfs is initramfs and the model is "Xiaomi Mi Router AX3000T (OpenWrt U-Boot layout)", which image should I go for?

I'm not sure if bumping threads is allowed, but I'm seriously confused as to what should I do. Any help, please?

You should clear the pstore.
rm -f /sys/fs/pstore/*
