Problem

I want to be able to update the endpoint on my android partner scanner in order to login to another company/server.

Solution

You will need to perform the following steps:

Login to the partner mobicontrol server https://partnermobi.taskletfactory.com/mobicontrol/
Remote Control your partner scanner
In the remote control window go to the file explorer (Tools → Explorer Tool (CTRL-E) to view/hide
In the explorer tree find your device and its file system
Go to sdcard\MobileWMS\Configuration where you will find the start.cfg file
Download the start.cfg and open the downloaded file in a text editor like notepad++ or VS Code
Change the endpoint in the <endpoints> section of the file to match your setup
Save the file and upload it to the sdcard\MobileWMS\Configuration location on the scanner (override the existing file)
Re-start MobileWMS and then the changes are taken into account
