which version are you using? does this still work with version > 3.* ?
Yes, I bet it is the newer firmware. Pretty much everyone suggests to downgrade to 1.0.16 or 1.0.18:

It should be quite easy and straightforward.
I am going to switch from the stock firmware to OpenWRT tonight or during the weekend, but I still have a few questions.
I got a new Redmi AX3000
From the instructions I see that it is necessary to downgrade to FW 1.0.17.
The router, however, does not let me do the downgrade, it fails file verification.
Is there anything that can be done ?
Thanks
