Excuse me? How to update the modified firmware？

[xztxy]

I downloaded your firmware, but I don't know how to operate it. Can you give me a detailed procedure?

which gateway do you use?
If M1S, you can enable telnetd. Then login by telnet, use fw_date to flash modified firmware.
If M2, you need to wire out the UART. Then use aqaraway.exe to flash it.

I also cannot flash the M1S. I tried to connect via UART and nothing came of it through aqaraway.exe. And how to enable telnetd and how to run fw_date I cannot understand. Maybe there are detailed instructions? my hub has been updated to firmware 3.2.6_0014.0517 and now it cannot update via the standard AQARA 3.2.6_0014.0524 application. another question is it possible to change the region from EU to CN

I remember that you enable telnet of gateway first, then use fw_update to flash custom firmware
To enable telnet, you can use the way 2 or way 3 in the website
Or you can use this integration. Just put M1S in Mija home and find out the token of gateway.

If you switch Aqara home, you need to flash custom firmware.
You need to download Putty.
Open putty, choose Telnet as connection type, then enter the ip of M1S.
Next step is to login with the username 'admin'.

If you get '#' prompt, enter the following command.

cd /tmp
wget -O /tmp/curl "http://master.dl.sourceforge.net/project/mgl03/bin/curl?viasf=1"
chmod a+x /tmp/curl
/tmp/curl -s -k -L -o /tmp/linux.bin https://github.com/niceboygithub/AqaraM1SM2fw/blob/main/original/M1S/3.2.4_0014.0520_mi_fw_ver_3.1.3_0011/linux_3.2.4_0014.0520_mi_fw_ver_3.1.3_0011.bin
fw_update /tmp/linux.bin
/tmp/curl -s -k -L -o /tmp/rootfs.bin https://github.com/niceboygithub/AqaraM1SM2fw/blob/main/modified/M1S/3.2.4_0014.0520_mi_fw_ver_3.1.3_0011/rootfs_3.2.4_0014.0520_mi_fw_ver_3.1.3_0011_modification.bin
fw_update /tmp/rootfs.bin

Then enter 'reboot' to reset gateway. After reset, you can switch M1S to Aqara home mode.

my hub has been updated to firmware 3.2.6_0014.0517 and now it cannot update via the standard AQARA 3.2.6_0014.0524 application.

M1S firmware 3.2.6 was removed by Xiaomi, so I did not get it before removed.
Use above the instructions, you can downgrade the firmware.

What you meaning? Do you mean the region of Mija Home app?
