The Ultimate Guide to the Evoko Liso Factory Reset (Verified & Step-by-Step)

Last Updated: May 2026

If you manage a modern office, you have likely encountered the Evoko Liso. As one of the leading room scheduling panels, it sits outside conference rooms to display availability, manage bookings, and integrate with Microsoft Exchange, Office 365, or Google Workspace.

However, like any sophisticated Internet of Things (IoT) device, the Liso can sometimes run into trouble. Perhaps the screen is frozen, the device is stuck on a boot loop, the Wi-Fi credentials have changed, or you are decommissioning a unit to sell it. In these scenarios, a simple reboot isn’t enough. You need a factory reset.

Searching online for the "Evoko Liso factory reset" yields many conflicting results—some suggest holding buttons that don’t exist, while others miss a crucial step that leaves the device bricked. evoko liso factory reset verified

In this verified guide, we will walk you through the complete, manufacturer-approved process to reset your Evoko Liso, including the secret "Safe Mode" protocol, post-reset configuration, and troubleshooting common errors.

Issue 1: "Certificate Error" after reset

Symptom: After entering your Exchange credentials, you get a security error. Cause: The factory reset may have retained an old SSL certificate (a rare bug in firmware 4.2). Fix: Perform a second factory reset, but this time, before rebooting, select "Wipe cache partition" three times in a row in the recovery menu, then wipe data again.

Option A: Standalone Mode (No management server)

  1. Select language and time zone.
  2. Network: Connect to Wi-Fi or plug in LAN (DHCP is default).
  3. Calendar Integration: Choose Office 365, Exchange, or Google. You will need your service account email and password, or the server address (e.g., outlook.office365.com).
  4. Room Resource: Enter the exact email address of the room resource (e.g., conference-room-a@yourcompany.com).
  5. Test: The unit will sync the next 48 hours of bookings.

Issue 2: Touchscreen unresponsive after reset

Symptom: The display shows the setup wizard, but touches do nothing. Cause: Firmware mismatch or static discharge. Fix: Unplug the device for 10 minutes (drain residual power). Plug back in. If still unresponsive, use a mouse via the USB port (the Liso natively supports USB mice) to click through the setup, then perform a calibration from the admin menu (pin: 1975).

  1. Disconnect power from the Evoko Liso.
  2. Remove the back cover (four screws).
  3. Locate the small tactile button labeled SW2 on the main PCB near the Ethernet port.
  4. Press and hold SW2 while reconnecting power.
  5. Keep holding until you see the factory reset confirmation on the screen (approx. 10–15 seconds).
  6. Release — device will reset and restart.

Step 3: Navigate the Recovery Menu

The touchscreen is disabled in recovery mode. You must use the physical pinhole button for navigation.

Use short presses to scroll down to "Wipe data/factory reset" . Long-press to select it.

Step 2: Enter Recovery Mode

This is where most online guides get it wrong. Do not just press the power button again.

  1. Disconnect the LAN cable (very important—live PoE can interfere with the boot sequence).
  2. Press and hold the power pinhole button again.
  3. While holding, connect the PoE (Power over Ethernet) cable or DC power adapter.
  4. Continue holding for exactly 10 seconds after the screen turns on, then release.

If done correctly, you will NOT see the normal Evoko logo splash screen. Instead, you will see a black screen with small white text in the top-left corner reading: "Recovery Mode. Warning: Factory reset will erase all data."
