Beijing Mobile replaces 2.5G optical cat XG-040G-MD by itself

Beijing Mobile 18 low-consumption broadband, add 18 yuan to speed up to 1000M, and the little brother said that this situation could not replace the 2.5G cat, so he had to do it himself.
Xiao Yellow Croaker Tao XG-040G-MD Mobile Version, the default password CMCCAdmin/aDm8H%MdA cannot be logged in, and it cannot be reset.
had no choice but to take out the TTL method and do it according to the posts of the gods.
rarely go to the forum, so I made a note and posted a post for my Beijing mobile friends in need.

1. Connect TTL
left to TTL programmer GND | The second from the left is TTL TX | Left third receives TTL RX

2. After the successful startup of the overrun password

enter password in user> enable
enter shell
screen prompt password:
enter the password LA (ImvZx%8
which is already root privileges
enter the following:
cfgcli -s InternetGatewayDevice.DeviceInfo.X_CT-COM_TeleComAccount.UserName CMCCAdmin
cfgcli -s InternetGatewayDevice.DeviceInfo.X_CT-COM_TeleComAccount.Password aDm8H%MdA

3. Modify the province
http://192.168.1.1/opid_setting.cgi Set "Beijing"
and it will restart

4. Modify MAC, device SN, model, etc
ritool set YPSerialNum SKYW12345678
ritool set MACAddress 1a:1a:1a:1a:1a (MAC English should be lowercase, there is a MAC address on the back of the cat, just copy it)
ritool set G984Serial 12345678 (this position is the last 8 digits of the device identification number)
ritool set MfrID SKYW (change the manufacturer's logo NBEL to SKYW)
ritool set Mnemonic SK-D746 (device model SK-D746)
the first 4 digits of Beijing Mobile's SN are the manufacturer name, and the last 8 digits are the serial number. The Internet says that only SN and Password are needed, I simply changed them thoroughly
after the change, verify it with the command:
ritool dump

5. Open telnet and change the root password (not required)
log in with overrun privileges to access:
http://192.168.1.1/system.cgi?telnet Enable telnet function
cfgcli -s InternetGatewayDevice.DeviceInfo.X_CT-COM_ ServiceManage.SuPassword xxxxxx
then remote telnet 192.168.1.1 to log in

6. Use route dialing or bridging according to your needs
For example, I use the bridge mode:
after modifying the province, this part will be configured as the routing mode by default, and I will change it to the bridge.
network - broadband settings - keep "2_INTERNET_B_VID_10", TR069 remote management and IPTV (starting with OTHER) are best deleted
connection method: bridge __ HTML49__ enable vlan: 10
802.1p: 4
LAN port binding: LAN1 (2.5G port), and do not need to check the others.

It is really troublesome to change the cat yourself, but it is worth it for speed. Resetting the password is invalid, although the TTL operation is complicated but effective, it is recorded for future reference, and it is hoped that Mobile will support the formal replacement process as soon as possible.
