Installation Instructions

Step 1: Put the saber in Deep Sleep and remove the SD card

Step 2: Download the appropriate Firmware package:

NeoPixel Version 3.30 ⤓ Release Date: Nov 15, 2022 In-Hilt LED Version 3.20 ⤓ Release Date: Nov 3, 2022

Step 3: Unzip the firmware

Step 4: Remove the SD card. Insert it into your computers micro-SD port or SD card adapter, and remove all file content inside of it.
Use a Windows PC or MacOS computer to do this. Mobile devices or chromebooks are not recommended as they will add formatting files to your card. Do not use a mobile device, chrome book or tablet for this process

Step 5: Place the dBoot.cry and Loader.cfg on to the SD card. Place these files into the root of your SD card, do not load them into a folder or sound font folder.

Step 6: Copy the sound font folder inside of the zip file below, and load it onto your SD card. Ensure you do not extract directly to the SD card, as this may put your sound font into a sub folder.

Kinetic 44.1kHz Sound Font

Step 8: Eject the SD card from your computer

Step 9: Place your SD card back into your Electrum Smart Saber®

Step 10: Toggle deep sleep to wake the saber (toward the speaker). The middle switch buttons will indicate that the saber is updating. Do not touch any buttons. Do not toggle the deep sleep switch during this process. Wait for the boot sound.

If your saber switch stops flashing, but does not finish the boot up after a minute, try touching the middle switch button. It is possible for old sleep settings to cause the saber to sleep during the update boot up, and waking it with the middle button will complete the boot up.

When you hear the boot sound your saber has now been hard-reset and is ready for use with the Electrum Unity II App. You can confirm the version of your software using the Electrum Unity II App with the settings icon.

Please note that the default name and model of your saber will be reset after this update, Typically showing an "Errant" saber model with a blank name or "Saber D3" name. This can be changed using the Unity II App. Refer to the Troubleshooting steps located below.

If the loading process does not start when you toggle the Deep Sleep switch, confirm that both the Loader.cfg and dBoot.cry files are in the root of your SD card, and try again. After the update completes, you will see 5 "Buffer" files on your SD card. These are normal, so don't remove them. The saber will take a moment on the first boot up after the update to create these.

Please watch the video below to see the Firmware Update process in action.

Step 11: Download and install the new Electrum Unity II App from the Apple App Store or Google Play store.

PLEASE ACCEPT ALL APP PERMISSIONS when opening the Electrum Unity II app for the first time. If you do not accept permissions, the Unity II app will not be able to connect to your Smart Saber.

Troubleshooting

• To update your saber model after the update is completed, you can tap the saber model name in the Unity II App dashboard, and select the model. Please note that newer devices and OS systems may take a few connections before a Saber Model or Name change is viewable for your saber, as the bluetooth cache needs time to refresh in your phone.
• Before performing any troubleshooting, please make sure your Smart Saber® is fully charged using a 5 volt 2 amp wall charger. Do not use computer USB ports, or low-power chargers (Apple iPhone cubes) or multi-port chargers. LOW BATTERY CAUSES MOST ISSUES that a user may experience.
• Make sure that all sound font folders you add contain NO special characters, including spaces, in the file names or folder names. Ensure the font folders contain no sub folders. Ensure all sound files are uniform 44.1kHz 16bit files, no mixed bitrates or low quality audio formats (22.05kHz) are supported.
• Ensure that any Sound Font you add to the Saber SD card has at least a hum.wav and boot.wav file.
• If you are experiencing issues with the saber restarting when attempting to power on, or audio issues with your sound font, please power down the saber and put it into deep sleep mode. Remove SD card and re-insert, then take the saber out of deep sleep and power on. If the audio issues persist, check your sound fonts to ensure they meet the standards outlined above. Re-test with an Electrum Sound Font. If issues still persist, please re-format the card (FAT 32 format) and put the sound fonts back on it.
  If this doesn't work, the card is most like damaged and needs to be replaced. The saber can support any high speed SD card formatted to FAT32, to a max of 32GB. We recommend a Sandisk Ultra 16gb.
• DO NOT TRY TO CONNECT TO YOUR SMART SABER USING THE BLUETOOTH DEVICE SETTINGS ON YOUR MOBILE DEVICE. You just need to accept the all permissions when opening the app for the first time. If you missed this step, re-install the Electrum Unity II App.
• Version 3.0 and greater use a NEW Hard Reset procedure. To perform a Hard Reset, toggle the deep sleep switch towards the saber emitter, and then back towards the speaker. When the lights on the touch switch stop flashing, hold the bottom button on the switch plate, and release when the switch plate lights begin to flash again.
