Modification Being that the hardware utilizes Linux-based software it can be changed or improved to their heart's content. The firmware is labeled as “QT Software” and varies from vendor to vendor. The upgrade contains multiple image files with the extension of img, along with other system files.
Flashing to upgrade the firmware can be taken advantage of as it does not seem to check if the version that is being installed is older. Due to this, using firmware made by the other vendors on the model each sold in particular is possible.
