Actually mine has been booted at most twice as I took it from storage only last week
I had some more devices that need the 2.4GHz and fail to connect to this firmware (Garmin watch, Google Chromecast), so I need to downgrade to 23.5.3.
What would be the correct way to do that?
The instructions I initially used fail:
dd if=factory.bin bs=1M count=4 | mtd write - kernel
Could not open mtd device: kernel
Can't open device for writing!
My AX6s has the new uboot:
grep ^U-Boot /dev/mtd2
U-Boot
U-Boot console

U-Boot BUG at %s:%d!

Luci warns me that the sysupgrade.bin file is incompatible:
The device is supported, but this image is incompatible for sysupgrade based on the image version (2.0->1.0). Invalid image type. Image check failed.
The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.
What would be the correct way to do the downgrade to 23.5.3?
Would be helpful if you provide:
ubus call system board
uci export network;
uci export wireless;
dmesg
logread
and/or if you can set log_level to the problematic network e.g.:
uci set wireless.default_radio1.log_level=0
uci commit wireless
<reboot router or restart httpd>
and share the logs when the device is trying to connect and it can't - that would be really appreciated.
If you want to go back (I never have done it before) - best way would be do same procedure as with debrick
Here is a part of logread, after setting loglevel of radio0:

Now 2.4GHz works again.
Do you have any Huwaei inverter for solar panels ? There is a known issue with inverters causing 2.4Ghz band to be stuck at 1Mbps when the inverter is connected (not specific to the AX6S).
Hi,
We don’t have solar panels here.
I have solved it by downgrading from the recent 6.6.30 based snapshot to an older 6.1.82 based snapshot.
I’m curious if others will report the same issue using the 2.4GHz band.
What if the count keeps increasing?
Then something is messed up with your fw_setenv commands.
My /etc/rc.local is below:
# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
# use slot 0, to be sure ;)
fw_setenv flag_last_success 0
# to survive 7 reboots with U-Boot 2014.04-rc1 (May 20 2022 - 10:19:21) or newer
fw_setenv flag_try_sys1_failed 0
fw_setenv flag_try_sys2_failed 0
exit 0What I mean is, if the change you suggest is not applied and count keeps increasing, could it stop booting?
Yes, it would softbrick the device: when flag_try_sys1_failed=7 then the bootloader switches autoboot from slot 0 to slot 1 and get stucked in boot-loop.
If you have serial access, then simply booting from slot 0 and setting those flags will restore normal boot.
flag_try_sys1_failed=12
flag_try_sys2_failed=8
Openwrt boots, but flag_try_sys1_failed keeps increasing by 1 on each boot, could it become an issue later?

If it passed 7 then it won't hurt! 
Would you mind showing all your flag? Simply fw_getenv fw_printenv | grep flag would do it!

Thank you!
Now I was able to test the new U-Boot (2022+) behavior:
flag_try_sys2_failed>= 6 andflag_last_success= 1 results booting from slot 0 andflag_try_sys1_failedincreasing till it overflows after 2^32-1 and continues at 0flag_try_sys2_failed< 6 andflag_last_success= 1 results booting from slot 1
withflag_try_sys2_failedincreasing till it reaches 6
It's the same with slot 0, just mirrored:
flag_try_sys1_failed>= 6 andflag_last_success= 0 results booting from slot 1 withflag_try_sys2_failedincreasing till it overflows after 2^32-1 and continues at 0flag_try_sys1_failed< 6 andflag_last_success= 0 results booting from slot 0 withflag_try_sys1_failedincreasing till 6
So without that /etc/rc.local workaround it's safer to stick to flag_last_success=1 as it will automatically fix itself after 6 reboots when those try_sys flags got lower than 6.

Hi,
I have RA80 Xiaomi AX3000 router using 1.0.46 firmware. Currently it is working in a xiaomi mesh mode. I was able to gain ssh access to it using patcher.

I bought new openwrt router and I would like to pair it with my existing xiaomi routers.
I need this as I have poe switch that is connected to wifi using xiaomi mesh mode.
I'm not sure should I install openwrt firmware, as it already has it, or upgrade it and install adition packages in this router.
This is router meminfo

Good results, but wrong thread!
Maybe this one is yours?
Yeah, I realized that after posting but I couldn't move it and didn't want to delete it.
Anyway I managed to convert router to openwrt. As I done it, I will briefly describe process. While flashing firmware my router was mesh node in xiaomi mesh.
I used this patcher to gain ssh access to router. Permanent access is also available.
In ~/.ssh/ create file named config and add to it
HostKeyAlgorithms = +ssh-rsa
PubkeyAcceptedAlgorithms = +ssh-rsa
After that you can ssh root@router_ip. Password is root.
I grabed firmware from this github repo. On the bottom of the page there are instructions in
Use miwifi (the vendor firmware) to flash
I tried to wget or curl this image from the router but no success. It will download empty file. I download it to my computer and done
scp *.ubi root@192.168.31.145:/tmp
Firmware is now copied to router /tmp directory. In that directory check curremt system slot like described in firmware repo and just run ubiformat on another slot.
Also after flashing run nvram commands and reboot router.
And that was it. Openwrt is installed on AX3000 RA80 Chinese model.
The only thing I noticed so far is that I get empty 5Ghz wifi on scanning but maybe some additional config should be used.
