This is firmware for iView Maximus III.
Both firmware versions are based on the last 6-digits of the Maximus III’s serial number.
If the last 6 digits start with QR, they would use the QR firmware.
If the last 6 digits start with VE, they would use the VE firmware.
Installing the wrong version of firmware could damage your device. Please kindly advise that we are not responsible for this situation.
