Maestro displays EEPROM INVALID after updating . I updated the app first, then used it to update 1.1.7 to 1.1.9. The app appears to be working. After uploading, the blue light went off. waited 2 mins. then turned off power. waited 30 sec, turned on and the eprom invalid message displays on 3 windows.
Tried this process twice, same results.

Going to post the steps here in case another user gets confused:

MIDI Maestro Firmware 1.1.9 and MM apps 1.6.x - Midi Maestro / Docs and Downloads - Singular Sound Forum

Updating the MIDI Maestro

  1. Update the MIDI Maestro App to the latest version in the App Store or Google Play Store
  2. Turn on your MIDI Maestro and enable Pairing Mode (hold the pairing button on the back of the unit for ~1 second). A blue LED will flash once the pairing mode is turned on.
  3. Go to the Hamburger menu in the app (top left) and select the Update Firmware option. Once the app has established connection you will see the MIDI Maestro blue Pairing LED stop flashing and turn solid blue.
  4. Allow the process to finish, the app will show the progress. Do not close the app, put your phone to sleep, turn off the MIDI Maestro, or change to another app while this is happening or you will need to restart the process.
  5. Once the firmware update is complete, you must rewrite the default modes to the device, the MIDI Maestro may turn off the BLE Pairing Mode automatically, turn the Pairing Mode back on again manually. Your MIDI Maestro screens may read EEPROM EMPTY, disregard this.
  6. In the app, reopen the hamburger menu and select the Update Default Modes option. Allow the process to finish, the app will show the progress. Do not close the app, put your phone to sleep, turn off the MIDI Maestro, or change to another app while this is happening or you will need to restart the process.
  7. Once the update is finished, power the unit off and back on again to see the update take place. You can verify the current loaded firmware on the MIDI Maestro on the bottom left screen of the main menu.
  8. Optional: Load in the custom mode currently open on the app by pressing the Upload to MIDI Maestro button in the Home screen.
