2 2  === Stepped Firmware Notes ===
3 3  
4 4  Some devices on older firmware may require "stepping" the firmware by updating to an intermediate firmware before updating to the latest firmware version. Currently installed firmware version can be checked with "**ver**" command, and the PUF version can be checked with "**ver -all**". The below list of devices may not be exhaustive and it is a good idea to check the update notes prior to updating firmware:
5 -
6 6  //**ZUM-HUB4** //processors must be updated to **PUF version 3.008.054** before being updated to **PUF version 3.009.0039 or newer**.
7 7  **//TSW-xx70 //**series touchscreens with** **firmware **below v2.001.0058** must first be updated to firmware **between v2.001.0058 and v2.006.0054** before being upgraded to firmware **v3.000.0110 or newer**
