    Dear Mr. Eric,
    I have connected this CMX TV box to USB External HDD (WD passport), but it seems that the power provided from the USB port is not enough to make my External HDD operational.
    So I added USB hub with extra power to overcome this issue.
    But sometimes this TV Box reboot by itself. I do not know whether the Extra Power has interfered this TV Box or something to do with power adapter of TV Box.

    Any advice?

  6. Hmm,it’s strange problem, maybe it’s power problem, i test with my 1TB hard driver, and i don’t met any problem. hard to make factory modify this. sir.

    Dear Mr Eric,

    Does your 1TB hard driver powered by outside power supply?
    I use Western Digital MyPassport 1TB.
    The same problem happened as well while connect to my Touro Hitachi 1 TB.
    To over come this problem, I use USB Hub with additional power supply.


  8. No,my hard driver don’t need outside power supply, maybe that’s the problem?

  9. Eric, I downloaded and installed this firmware and now it kept doing the “Android is upgrading…” upon each boot-up and it doesn’t retain my changes/settings. If I remove the SD card from the unit, I don’t get this message, but instead I get the stuck “MBOX” image and won’t continue any further. Do you know what causes this issue or how to fix this? or is my unit defective?

  10. Hi Your device is not defective, you just don’t know how to flash the firmware correct, please follow my instruction, and flash again, after you flash successfully, please delete the firmware from your SD card.

    Does this CMX TV Box support Bluetooth? The seller “” keep insisting that the Bluetooth worked on this Box; but I can never turn on the Bluetooth in the Settings! Either the seller’s QC workers don’t know what they are doing or no QCs has been conducted at all?

    Why would we want to download this Stock Firmware when the CMX TV Box has the same firmware already installed from the factory?

  13. I need this file , please reupload to another host, the download speed is very slow .
