2B Firmware

Category: Downloads

The E-Stim System 2B is one of the very few E-Stim power boxes available today that allows you to easily update its internal control software, normally referred to as 'Firmware'.

Firmware Upgrades

The firmware files are encrypted data files. Do NOT attempt to edit them as corrupted data files could potentially damage your 2B and will invalidate your lifetime warranty. To download, right click on the download link below and 'Save Target As' to your computer. Click for further instructions on how to install the Firmware.

Minimum requirements

Version 2.09 is the minimum required to operate with Commanderâ„¢. 2.104 has the bootloader installed, but if you are upgrading from an older release the you will need to install the bootloader first.

You do NOT need to install older firmware updates first in order to install the latest versions., the latest firmware version will have all the options and bug fixes of earlier releases.

Beta Files

Please note BETA files (marked with a 'B' in the version) have not yet been fully tested, and may have bugs. If you find any please report them on our our User support forum. Before attempting to download and install BETA files, you must ensure that you are running the latest version of UpLink, and have the latest Bootloader installed.

Having Problems

If you 'brick' your 2B and cannot provide the log file, or you have installed a beta that failed, then you will have to return your 2B to our workshops for an upgrade. A workshop repair/upgrade is a chargeable service.
