    M8S S812 – lovely box just a great shame that they’re not set up correctly. My first one looks like whoever set it up fell asleep on it. Sent that back and got another equally as bad. Now on 4th and its just as badly setup. Then you get the farce with the firmware that end up bricking them. Is it too much to ask to have the correct firmware listed by the actual boxes. Not this hit amiss? Certainly put me off buying these again and certainly would not recommend either.

    Using the burning tool. I have a connection, but I cant get any up grade or recovery to load into the burning tool.
    I haven’t gone in the box yet and jumped anything. should I be able to load the burning tool even before i go to this step.

    Hi, i had totally wiped the android operating system from my M8S box by accident. So i was left with a box that would load its operating system at all, but display a blank screen with just the time on the top right corner of the screen.

    I was unsure of the above firmware for my M8S, so after hours of research i came across a website that helped me get my M8S box back up and running. It was fairly straight forward, and i used a 4GB SD card (2GB Is Fine) to transfer all 5 files from the zip file to the SD card, and then i inserted the SD card into the M8S box on the side, and pressed down on the reset button with a pin in the AV port at the back of the M8S, and then while the reset button was pressed down i inserted the power cable into the back of the M8S box, and nothing appeared, but i still kept it pressed and the screen black screen flashed from on to off approximately 8 times, before the android logo appeared, and the SD card was then recognised as the files on the SD card were being installed.

    The 5 Files are named as follows:

    All of these files within the ‘M8S’ zip file need to be transferred over to the SD card.

    link to where i had found this version of android for the M8S box is:

    The M8S files within this article i did not try as i was unsure of what would do to my box.

    I have no participation in creating any of the files, and i hope this post can help someone, because i know what it feels like to think your M8S box is dead.

    Yes, I would like to request the latest n200 firmware for my M8S Android box as I cannot find it any where. The latest firmware I have on my box is dated Feb, 2015.
