Firmware Upgrade T46S not working
I'm trying to upgrade a few T46s with factory firmware:
Code:
Firmware Version: 66.82.161.1
Hardware Version: 66.0.0.128.0.0.0

Right now I don't have physical access, so no recovery from telnet tested.

From WEB UI tested firmware upgrade:
-> Directly to V86 nothing
-->Intermediate firmware: V83,V84,V85
Version didn't change.
Tried downgrade to v82, also dind't change.
This issue happened to all T46s with that firmware.
