I get telnet to my router ZTE H267A given by TM and running VDSL2 on 50mbps plan (last time 30mbps but auto upgrade 50mbps) (2.4GHz seems to be cap at 30mbps and wont go up)
I successfully got logged in into the CLI of ZTE H267A which running on Software Version V1.0.0_MYT3A and Boot Version V1.0.2.

The CLI default username is admin and password is public which is work for me and i get successfully login.

The ZTE H267A Log also shows that CLI Login Successful.

I found out although i successfully log in to the CLI but it shows up require a password to enable privileged commands or else you can only use the ping command or exit telnet.

I tried the default password zte and i get successfully log in to the CLI Privileged Commands

I saw many command that didn't show up when im not login to the CLI Privileged Commands including shell
I tried to get into shell but it require password and username again. The default username is admin and password is admin. I tried and also get successfully login.


Conclusion :
CLI Login Username : admin
CLI Login Password : public

Privileged Commands Password : zte

Shell Username : admin
Shell Password : admin

I literally don't know what can do with this shell. I hope there is any people can use this tutorial and install DDWRT or any other Router OS to the ZTE H267A and let the router able to meet the maximum performance and features of this router.

Good job, but if I were you, I wouldn't bother and just get another better router rather than hacking TM's router. You can change the software, but if hardware is not good, there's no point.

No choice, have to keep this router as the VDSL2 modem and use it on bridge mode for condo users.

Ya I did change the ZTE H267A to only a router but not for AP , i get DIR 865L AC1750 for RM30 and DIR 850L AC1200 for RM30 and make DIR865L as router in living room and DIR850L as AP Mode in my room

It seems to be able to get the TP-Link AC1200 VDSL2 Modem+Router+VoIP for the UniFi VDSL2 users
