Please use your mobile phone's Bluetooth to connect and see if it can be connected. If it can be connected, use software "Cubesuite" to upgrade it.
There is no way for the computer to perform Bluetooth OTA upgrades. You need to download the APP "cubesuite" on your phone/tablet to upgrade.
Please scan the QR code to download.(See the picture)
If it fails, please upgrade several times. It is recommended to use mobile phone OTA upgrade.
Please try a few more times. If it doesn't work, use an iOS phone to upgrade.
Warm reminder: During the upgrade process, please do not cut off the power of the device; during the upgrade process, the device will enter a black screen state. Please do not do any operations.
