If the Cube does not start

The Cube does not start on twist - it is either discharged or is shut down

Solution: place it on a charging station connected to a power source to turn it ON.

---

Not all screens lit up when I put it on the charging base

Most likely some of the modules got deeply discharged

Solution:

• Let the cube charge for 10 minutes
• Press and hold the button on the charging station for 10-12 seconds
• The cube will restart with all modules booting up

Module unresponsive

One or several cube modules become unresponsive - they do not react to taps, shakes, or twists, and display either a black screen or frozen game graphics.

Solution: Reboot the cube by placing it on an unplugged charging dock. Wait at least 10 seconds for the cube to reboot.

One screen not working

A single screen on a cube module is malfunctioning - showing inverted colors, colored lines, or a blank display.

Solution: Reboot the cube. If the problem persists, please contact us at [email protected].

If the Cube shows an Error

Please follow the instructions displayed on the cube screens, and in the mobile application.

Also, you can try restarting the cube and/or the mobile application.

Don't hesitate to contact us at [email protected] if the problem persists

What does Internal error (2) mean ?

It means that the process of installing a game or a firmware update has finished with errors or has been interrupted, and you need to re-start the process from the beginning.

Normally, you will see the corresponding error message in the mobile app with the option to Try again.

If the 'Try again' option does not help, perform a reboot of the cube by placing it on an unplugged dock-station

I did a factory reset of my cube and now it says 'Firmware error. Corrupted assets'

No worries - this is the expected behavior after performing a factory reset on your WOWCube.

After the reset, the cube is temporarily missing a mandatory file with platform resources, so you need to re-install the firmware as instructed on the WOWCube screen.

Before re-connecting to the cube please make sure the cube is removed from the list of paired devices in the system settings of your phone:

• Open the system Settings app
• Go to Bluetooth
• Find your WOWCube in the list of paired devices
• Tap on the {i} icon for iOS or the 'cog' icon for Android, next to the cube name
• Tap 'Forget device' for iOS, or 'Unlink' for Android device
• Restart the mobile application "WOWCube connect"

If, for some reason, installing the firmware update fails from this state, reboot the cube by placing it on an unplugged dock station and waiting for 10 seconds, and try again.

Cube says Firmware Update Required

One or several of the Cube modules have reverted to the factory FW version or have not updated to the latest FW version, and hence not in sync with other modules.

This can perhaps happen when the FW update process has gone wrong on a particular module

If you have faced with this - use the 'Restore Firmware' button in the Firmware section in mobile app, it will reload the latest FW from the server to your Cube, and so all modules will have the same FW version again.

Can't login to mobile app, it's got stuck at Loading screen

Solution: most likely your mobile web-browser is blocking opening external apps, so you need to disable the corresponding option in the browser settings. Here is an example of such a setting in the Microsoft Edge

My Cube catches/jams

Ensure that your Cube is properly tightened, avoiding excessive tightness or looseness. Use a cross-head screwdriver to adjust the Cube tension, focusing on the 6 screws, each located in the center of every Cube face. Clockwise to tighten and increase tension, and vice versa.

Legacy Hardware (Old Hardware Version)

This section covers issues specific to the older version of WOWCube hardware.

How to identify Legacy Hardware

Check the charging dock: if it has no LED strip lighting along the bottom perimeter, you have the legacy hardware version. Newer hardware docks have a visible LED ring/strip around the base.

Cube loses charge while on the dock

Symptom: The cube drains battery even when placed on a connected charging station.

This is a known limitation of the legacy hardware charging circuit.

Solution:

• Make sure the dock is connected to a stable power source (avoid low-power USB ports or hubs)
• Clean the charging contacts on both the cube and the dock with a dry cloth
• If the above did not help, try charging your cube in two halves as described down below
• If the issue persists, contact us at [email protected]

Cube won't turn on after long period of inactivity

Symptom: After the cube has not been used for an extended time, placing it on the charging dock does not turn it on. The cube remains unresponsive.

This happens because individual modules have deeply discharged below the recovery threshold. When assembled normally, the cube attempts to charge all 8 modules simultaneously, which is too much to recover from deep discharge. To work around this, the cube needs to be charged 4 modules at a time by isolating the top and bottom layers from each other with a half-twist.

Solution — charge the cube in two halves:

1. Twist the cube halfway to misalign the top and bottom layers — this isolates them electrically and ensures only the 4 bottom modules are charged at a time
2. Place the cube on the dock in this half-twisted position
3. If the cube does not respond at all, reset the dock: flip the toggle switch on the charging station to position 0, then flip it back to the charging position. This forces the modules to restart and begin accepting charge.
4. Leave the cube to charge for 1 hour
5. After 1 hour, remove the cube from the dock, flip it upside down, and place it back on the dock so that the other 4 modules are now facing down
6. If needed, reset the dock again using the toggle switch as described in step 3
7. Leave it to charge for another 1 hour
8. After both halves have been charged, twist the cube back to its normal assembled position —it should now be able to start normally

Note: Do not interrupt the process — each half needs the full hour to recover from deep discharge.

Cube stuck on logo screen (all 8 modules)

Symptom: The cube cannot boot and shows the WOWCube logo indefinitely on all modules. The cube does not respond to taps, twists, or shakes.

How to confirm this is firmware corruption and not a regular freeze:

Look closely at the logos displayed across the modules. If one or more modules show a smaller logo than the rest, those specific modules have corrupted firmware and are preventing the cube from starting.

Solution — use the Recovery Tool:

The Recovery Tool is a plastic insert included in the box with your WOWCube. Each affected module must be recovered individually, one at a time.

1. Locate the Recovery Tool (small plastic insert from the original packaging)
2. Bend the Recovery Tool so that the "inside" label faces inward (is on the inner side of the fold)
3. Identify a module showing the smaller logo
4. Insert the bent Recovery Tool into the gap between the modules, wrapping it around the affected module so that it grips the module from both sides
5. The module screen will display a circular arrow icon and a progress bar
