Help to downgrade from EZSP 7.4.X.X to EZSP 6.8.X.X

[PMP74]

I had upgrade the ezsp to EZSP 7.4.X.X but discover that not working with the version I have. Not able to downgrade to older version.
I do it as I had issues with zigbee map, and thought would help to solve the issue. Now I have Tasmota V 15.0.0 but zigbee radio is off

Details of what you mean by "not able to" can be pretty important for how to do something about it. Anyway, some types of EZSP downgrade trouble seems to be fixable by temporarily downgrading Tasmota to a rather old version, like 9.1.
