Hi Arun,

please check output from following commnad

xstatus SystemUnit Hardware Module CompatibilityLevel

If it is 3 then you will not able to downgrae to TC 5.1 .

If it is 2 then it can be downgrade to TC 5.1 , you can downgrade to TC 5.1.6.

Please refer release note .page 93 for detail information .

Hey Arun,

It migh tbe already there. try this.

get the root ON.

systemtools rootsettings on

and now login as 'root'

issue

selectsw

See if we have two images there..

if so you can check the version ..

by

cat /mnt/base/image1/version

cat /mnt/base/image2/version

and also verify the release keys installed..

cat /mnt/base/active/rk

Then if you find every valid do the

selectsw image2   or image image 1   accodingly which ever shows as TC5.1.

You can also try to go on TC6.0.0 first then to TC5.1.0

Hi Arun,

Make sure you are using the correct TC5.1.0 file for Sx20

For SX20 we use s52010tc5_1_0.pkg file as mentioned by Dharmesh earlier.

ftp://ftp.tandberg.com/pub/software/endpoints/tc/tc5/Deferred_Releases/s52010tc5_1_0.pkg

Also you can try to Downgrade the device using WinScp.

The link to use WinScp is mentioned below which is mentioned on page 13:

https://supportforums.cisco.com/docs/DOC-15643

Make sure to rename the software file to just "pkg" and the root is enabled, if it is not enabled, you can enable the root by login in as admin and then run the command:

systemtools rootsettings on

Drag the file and copy it to the Upgrade folder of the device, after the upgrade the device will reboot and will upgrade.
