Multy M1 - new firmware V1.00(ABZF7)C0

boonshth

Hi Zyxel support,

I have 3 M1(WSM20) installed and found that my latest firmware version is V1.00(ABZF)C0 that still have technical issues (mentioned in this community). I think they were automatically upgraded by system.

Currently, some M1cannot check the status by Diagnose feature in Multy app..

Any suggestion to downgrade my M1 to the reliable firmware?
