Hello,


Im trying to downgrade one of our installation made of M900 antennas. Their actual firmware is 650B2 and i willing to downgrade them back to 530B2, but it's not working.


I've been trying with the master of a clusters, differents antenna that are outside of multi-cell, desactivated my firewall, changed my network, tried differents switch, but still nothing works (even when im trying to upgrade one that is in 530B2 to 650B2 it wont work).


3 weeks ago one of my collegues did downgrade one of our installation and it worked fine.


Is there any suggestions that could help ?


(im putting https://dect.snom.com in "update server address" ; 530 in "required version" ; 02 in "required branch")


PS: the reason we decided to downgrade is because with the 650B2 our client had somes problems, but with 530B2 firmware everything works fine.


Thank you !

  1. Hi, we have had some issues with the firmware download server for the past few days. I advise you to try again, or do the operation via local network: How to update M300,M700,M900 and handsets via Network
