HT-M01S firmware issues

I updated my HT-M01S to firmware 1.3 and now it just does a boot loop after connecting to the wifi network. Using - and reset, I can connect to the gateway via wifi and go to it asks for a username and password, which does not work with HT-M01S and as username and password. I would like to just roll back to V1.2.

Ok. I was able to downgrade the firmware back to v1.2 and it is working again following this guide.

Do you mean that the user name “HT-M01S” and password “” cannot enter the configuration page normally in the V1.3 version?
