Issue with downgrading TE30

Publication Date:  2018-02-27 Views:  363 Downloads:  0

Issue Description

Issue with downgrading TE30 terminal from V600R006C00 to V500R002C00SPC500. 

Handling Process

1.Recommended using the upgrade tool, using a straight connection to the endpoint and checking if the Upgrade password is correct.

After trying the downgrade the end user was receiving the following error:

2.Requested the hardware version of the endpoint and verified that it has an F board.

3. Checked if from Hardware Board F the downgrade is possible to V500R002C00SPC500 and found it is not possible from V600R006C00 to the target version.


Root Cause

Due to hardware changes the F board cannot be rolledback from V600R006C10 to any V500R002C00SPC***. Version V600R006C00 can be downgraded to latest V500R002C00SPC900.
