When updating to the ver. 2.0 Echolution 2 application and firmware, you must update the firmware FIRST (using the old app) and THEN update to the 2.0 app.
If you update the app first, when you then update the firmware, the app will crash and disconnect.
If you updated the app first and can’t update the firmware, you will need to:
1) UNINSTALL the 2.0 app
2) Go to https://pigtronix.com/E2application/Legacy%20E2%20App%20%28Version%201%29/ and download the Legacy E2 App (choosing the right platform for your computer: Linux, Mac or Windows)
3) Install the Legacy E2 App
4) Update the Firmware: click on File>Update Firmware in the app and navigate to the 2.0 firmware file (wherever you downloaded it to). The file is called “e2update.dat”.
5) Update the App: Go to https://pigtronix.com/E2application/ and download the applicable app version, and double click on the file to install.
If you haven’t updated to 2.0 app and firmware yet, simply open your app and follow steps 4 and 5 above before you update the application to version 2.0.
