I 've been having issues to upgade firmware to 3.1, current firmware is  2.2. CNUT seems to be running the firmware upgrade and show the progress bar, till it reaches 100% but it doesn't do anything. Can somebody tell me what am I missing?  ---

Hi Kdrama, Are you using CMM3? If Yes, please follow the below procedure to upgrade the CMM. 1. Connected the CMM3 directly to Laptop. 2. Configure the appropriate IP to Laptop. So that the laptop can ping and access the CMM. 3.  Access CMM GUI and set the "Full access password" e.g. 123456, for the hidden user account "root". 4. Save and rebooted the CMM3. 5. Open CNUT \>\>\>Discover the CMM using following credentials. a.  Uncheck "use default/inherit settings from parent elements. b.  login-id: root, password- 123456, SNMP Community string- canopy, snmp ver-v2c. NOTE: SNMP Read/Write Sting should be same as in CMM. c. Type in the IP address of the CMM in Discovery Target box and click OK. 6. Now, upgrade the CMM to 3.1 version. This will successfully resolve your issue. Please let me know the  result once, you are done. Regards, Vijay Gnanamurtthi. ---

I have a CMM Micro and have CNUT 4.6.9 running on my pc First thing I do is  to add the network element, enter password  and IP address to be discovered. It does discover my CMM , I select package to be upgraded and progress bar stars with 25% then 50% and 100% supposedly it was completed. I refresh network element, but old firmware remains ---
