Xiaomi AX3600: help installing openWRT 24.10

alfredo · August 16, 2025, 8:03am

Hi,

I need help about installing openWRT 24.10. I followed the detailed procedure here and I was able to obtain SSH access and to flash the “intermediate” firmware as described. The command

nvram get flag_boot_rootfs gave me 1

so I used

ubiformat /dev/mtd12 -y -f /tmp/openwrt-qualcommax-ipq807x-xiaomi_ax3600-initramfs-factory.ubi -s 2048 -O 2048 && nvram set flag_boot_rootfs=0 && nvram set flag_last_success=0 && nvram commit

I do not remember about the output of cat /proc/mtd.

There were no errors, however after reboot the blue LED is on and the LAN/WAN LEDs are all blinking, but I am not able to get an IP address in order to complete the flashing procedure.

So I tried to unbrick the device following the TFTP recovery on GNU/linux, but even if the orange LED blinks and the TFTP server is working on my PC, I am to able to recover the device.

What can I do?

Thank you

Hi,

I tried again. When I switch on the router, the LED stays solid orange for a few seconds, then blinks rapidly in orange, followed by a slower blinks orange, and finally stays solid blue. I cannot get an IP address, so I tried configuring the PC with a fixed IP of 192.168.31.10, but I could not ping the router.

So I tried again the TFTP recovery procedure:
sudo ip address flush dev adapter_name
sudo ip address add 192.168.31.100/24 dev adapter_name
ip a
2: : <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
inet 192.168.31.100/24 scope global adapter_name
valid_lft forever preferred_lft forever

sudo dnsmasq --no-daemon --listen-address=192.168.31.100 --bind-interfaces --dhcp-range=192.168.31.2,192.168.31.2 --enable-tftp --tftp-root=/tmp/tftp
dnsmasq: started, version 2.90 cachesize 150
dnsmasq: compile time options: IPv6 GNU-getopt DBus no-UBus i18n IDN2 DHCP DHCPv6 no-Lua TFTP conntrack ipset nftset auth cryptohash DNSSEC loop-detect inotify dumpfile
dnsmasq-dhcp: DHCP, IP range 192.168.31.2 -- 192.168.31.2, lease time 1h

dnsmasq: reading /etc/resolv.conf
dnsmasq: using nameserver 127.0.0.53#53
dnsmasq: read /etc/hosts - 8 names

I switched of the router and pressed the reset button until the orange LED started blinking. However, it did not turn blue, but remained solid. If I do not press the reset button, the router follows the LED status as described in the first part of this message.

What can I do?
Thank you

does it even request an IP from dnsmasq/DHCP ?

alfredo · August 21, 2025, 1:58pm

No, the output is the one that I reported.

sudo dnsmasq --no-daemon --listen-address=192.168.31.100 --bind-interfaces --dhcp-range=192.168.31.2,192.168.31.2 --enable-tftp --tftp-root=/tmp/tftp
dnsmasq: started, version 2.90 cachesize 150
dnsmasq: compile time options: IPv6 GNU-getopt DBus no-UBus i18n IDN2 DHCP DHCPv6 no-Lua TFTP conntrack ipset nftset auth cryptohash DNSSEC loop-detect inotify dumpfile
dnsmasq-dhcp: DHCP, IP range 192.168.31.2 -- 192.168.31.2, lease time 1h
dnsmasq-tftp: TFTP root is /tmp/tftp
dnsmasq: reading /etc/resolv.conf
dnsmasq: using nameserver 127.0.0.53#53
dnsmasq: read /etc/hosts - 8 names

I am using ubuntu 24.04. My /etc/hosts

127.0.0.1 localhost127.0.1.1 myPC

The following lines are desirable for IPv6 capable hosts

::1     ip6-localhost ip6-loopbackfe00::0 ip6-localnetff00::0 ip6-mcastprefixff02::1 ip6-allnodesff02::2 ip6-allrouters

and /etc/resolv.conf

nameserver 127.0.0.53
options edns0 trust-ad
search lan

Edit: same problem of this with official build.

frollic · August 21, 2025, 2:53pm

NSS builds aren't official.

Can a different client than the router obtain an IP from this dnsmasq?

alfredo · August 27, 2025, 3:19pm

Hi,

I am using the official build and I followed the instructions here.

I have to try. Is it enough to connect any kind of device?

Thank you

frollic · August 27, 2025, 6:04pm

Yes, you just want to see if it works as intended.

alfredo · August 28, 2025, 3:45pm

I tried with a different PC running ubuntu 22.04 LTS and I discovered that the router was working properly (although all the LAN LEDs are constantly blinking). I was able to access the router via LuCi and configure it. Probably, the other PC, which does not have an integrated LAN port, but only a USB adapter, has some problem.

Thank you

I tried to install a package withopkg update and than opkg install nano htop

Collected errors:

opkg_download_pkg: Package nano is not available from any configured src.

opkg_install_pkg: Failed to download nano. Perhaps you need to run 'opkg update'?

opkg_install_cmd: Cannot install package nano.

opkg_download_pkg: Package htop is not available from any configured src.

opkg_install_pkg: Failed to download htop. Perhaps you need to run 'opkg update'?

opkg_install_cmd: Cannot install package htop.

What could be the problem? The router connects to Internet and devices can access Internet.

Thank you

frollic · August 28, 2025, 5:08pm

Might want to post the complete opkg output, not only the error message.

alfredo · August 29, 2025, 7:47am

Hi,

I was able to install all the packages except luci-app-wireguard, but it found that is not available anymore.

I am sorry, I do not understand why it never works on the first few attempts.

frollic · August 29, 2025, 7:52am

yeah, it's been renamed/superseded.
