Evoko Liso Factory Reset Verified May 2026

A verified factory reset of an Evoko Liso requires a firmware re-flash using a FAT32-formatted USB drive containing the latest firmware files in the root directory. The process involves powering down the unit, inserting the USB, and waiting for the "Flash has been successfully completed!" message to confirm the device has been wiped and restored.

General Steps for Factory Reset on Evoko Liso

1. Backup Important Data: Before you proceed with a factory reset, ensure you've backed up any important data or settings. A factory reset will erase all data on the device.

2. Access Settings: Typically, a factory reset can be initiated from the device's settings menu. Look for an option like "Settings" or "System" on your Evoko Liso.

3. Find the Reset Option: Within the settings, search for an option like "Backup & Reset," "System Reset," or simply "Factory Reset." The exact wording may vary.

4. Confirm the Reset: You will likely be asked to confirm the reset. Ensure you're ready to lose all data on the device.

5. Perform the Reset: Follow the on-screen instructions to complete the factory reset process.

Feature: Zero-Touch Recovery (ZTR) Provisioning

Concept: Currently, a factory reset wipes the device clean, requiring an administrator to manually re-enter Wi-Fi credentials, server URLs, and pairing codes to make the device operational again.

Zero-Touch Recovery allows a factory-reset Evoko Liso to automatically retrieve its last known configuration and identity from the Evoko Home server, eliminating the need for manual re-provisioning.

How it works:

1. Secure Handshake: When a factory-reset Liso boots up, it enters "Discovery Mode." It sends a secure "I am here" signal to the local network broadcast address.
2. Server Recognition: The Evoko Home server (on the same network) recognizes the device's unique Hardware ID (MAC address) in its database of previously registered devices.
3. Auto-Enrollment: The server pushes the saved configuration profile (Wi-Fi credentials, SIP account details, Room Name, and Theme) back to the Liso unit.
4. Operational Status: The Liso applies the settings and transitions directly to the booking screen, fully operational without human intervention.

Key Benefits:

• IT Efficiency: Eliminates the "truck roll" or desk visit typically required to reconfigure a reset device.
• Disaster Recovery: If a device malfunctions, a user can perform a factory reset to fix the issue, and the room is back online in minutes automatically.
• Hardware Swaps: If a unit is defective, a replacement unit can be programmed with the old unit's ID, allowing it to inherit the configuration instantly upon boot.

The primary "verified" method for factory resetting an Evoko Liso is a Firmware Reset using a bootable USB drive. This process is essential if you have lost the administrator PIN or the device is unresponsive.

Method 1: Firmware Reset (Verified for Forgotten PIN/Locked Devices) evoko liso factory reset verified

This method completely wipes the device, unbinds it from Evoko Home, and resets it to factory defaults. Prepare the USB Drive:

Download the Liso Device Reset (GZ file) from the official Biamp/Evoko Downloads.

Use imaging software like Etcher, Win32 Disk Imager, or Rufus to flash the GZ file onto a USB drive (at least 4GB).

Note: Kingston USB drives are often incompatible with Liso panels. Perform the Reset: Power off the Liso by disconnecting the PoE or power cable. Insert the USB drive into the port on the back.

Power on the device. It should automatically boot from the USB.

A 30-second countdown will appear. Allow it to finish to start the flash.

Once the message "Flash has been successfully completed!" appears, remove the USB and reboot the device. Method 2: Admin Panel Reset (Requires PIN)

If you still have access to the admin settings, you can reset or update without a bootable USB.

Tap the three-line icon (or "i" button) on the screen and select Admin Login.

Enter your Administrator PIN or use an authorized RFID card.

Select Update via USB (using a standard firmware package rather than a reset image) to refresh the configuration. Important Notes Updating Liso Firmware - Evoko - Biamp Cornerstone

To perform a verified factory reset on an Evoko Liso, you must use a physical USB reset drive. This process is necessary if you have lost the admin PIN, if the device is not working properly, or if you need to disconnect it from Evoko Home. Required Equipment ("Proper Piece") USB Drive: You need a USB drive with at least 4GB capacity.

Note: Kingston USB drives are known to be incompatible with Evoko Liso. Ensure the drive is physically small enough to fit into the recessed USB port on the back of the device. Factory Reset Procedure

Prepare the Reset Drive: Download the latest Liso Device Reset (GZ file) from the official Biamp Downloads page. Use imaging software like Etcher, Rufus, or Win32 Disk Imager to flash this file onto your USB drive (this will erase all data on the USB). A verified factory reset of an Evoko Liso

Power Down: Turn off the Liso by removing the PoE or power cable.

Insert USB: Plug the prepared USB drive into the USB port on the back of the Liso.

Power Up: Re-insert the PoE or power cable. The device will automatically detect the USB and display a countdown on the screen.

Confirm Flash: If you do not interact, the flash will start automatically after 30 seconds.

Completion: Once finished, the device will restart and display the initial Configuration screen, indicating it is ready to be set up as a new device.

If you still have admin access and only need to change settings without a full wipe, you can log in using the Default Admin PIN 0000 (if it hasn't been changed). Updating Liso Firmware - Evoko - Biamp Cornerstone

Performing a factory reset on an Evoko Liso room manager is a verified process that restores the device to its original out-of-the-box state, wiping all network settings, local configurations, and server pairings. Unlike newer models that may use a simple pinhole button, the Liso requires a firmware reset USB drive to trigger a full system wipe and reinstallation. When to Perform a Factory Reset

Lost Admin PIN: If you cannot access the administrator panel and do not have the pairing key.

Connection Issues: Persistent failure to sync with Evoko Home or network timeouts.

System Migration: When moving the device to a completely different network environment or server that does not support a standard migration. Step 1: Create a Bootable Reset USB

You cannot simply use a blank USB; you must create a bootable "flashing" drive using imaging software like balenaEtcher.

Download the Image: Get the latest Liso Device Reset (.gz) file from the official Biamp/Evoko Downloads page. Flash the Drive: Insert a USB flash drive (all data will be erased).

Open Etcher, select the downloaded .gz file, and target your USB drive.

Click Flash!. Once complete, the drive may appear as "Boot imx6dl" and might trigger Windows "format drive" errors—ignore these. Step 2: Execute the Factory Reset Device is unresponsive or misconfigured

This process will overwrite the internal storage of the Liso.

Power Down: Unplug the PoE (Power over Ethernet) or power cable from the back of the Liso.

Insert USB: Plug the prepared reset USB into the port on the back/side of the device.

Power Up: Reinsert the power cable. The Liso will detect the USB and boot into a reset utility instead of its normal OS. Verification:

A message will appear: "If you do not want to flash the device, remove the USB... otherwise it will start flash in 30 seconds". Do nothing and let the countdown finish.

The screen will display a progress bar. Once finished, it will say: "Flash has been successfully completed!".

Reboot: Unplug the USB and powercycle the device. The Liso will now boot to the initial "Configuration" screen. Step 3: Post-Reset Reconfiguration

After the reset, you must re-pair the device with your server.

Evoko Home Preparation: On your server, ensure the Device Registration Timer is active (found under Global Settings) to allow the newly reset device to connect.

Initial Setup: Follow the on-screen prompts on the Liso to enter your Server IP and select the designated Room. Factory Reset via USB Admin Panel "Update" Data Kept? No (Full Wipe) Yes (Updates OS only) Admin PIN Required? Use Case Brick recovery, lost passwords Routine maintenance
