As we have updated the security mechanism on this beta firmware, once you have upgraded to this firmware, you will not be able to downgrade to the old one.
However it is allowed to upgrade to a new official firmware that will be published recently.

Added the IPv6 stateless configuration feature.
Solved the problem that your modem router can’t successfully obtain IPv6 address from your ISP.

The new beta firmware worked normally in our test LAB, now we are waiting for the further test results from our customers.
