    It does have problems with bluetooth. It connects, it pairs but nothing happens after that.

    Tks.

    Thanks Higgs but when the device restarts in the right moment the batch tools will write the firmware it says: "Wait for Loader starts" and wait forever.

    It looks like after upgrading to 4.4.2, it partitions the device in a way tha doesn't alow you to change those "partitions" anymore to rollback to JB.

    Still trying - almost a week now - with all kind of tools I can find at the web.

    I haven't tried the process and don't have any devices to do so. All I can say is that despite what you wrote elsewhere, not 'everyone' was unsuccessful following this guide.
    Have you tried with an older pc (win XP or Win7), as I did read there were issues with Win8.1.

    Does that mean that you got it working?

    Yes! I was able to do the downgrade just moving to other pc with win7. Piece of cake.

    The problem was the operating system Win8.

    Tks.

    Good morning to all !

    I wanted to go from 3.1 to v10 Quickshot officer.
    I followed these instructions sent by comrade ALDSA:

    http://www.minixforum.com/threads/downgr...only.5218/

    Once the process is completed with 1.70 RKBatchTool.exe, I tried to load the V10 with the same program and will not let me, says file error.

    The problem is that I know I have to do to include him v10 nor how. The x7 enters recovery without problems but I know I have to do

    Please help me ¡¡¡

    Make sure the file you downloaded is correct by checking the md5 checksum.

    Could you explain how I do it?
    I am a rookie and after following the steps, continue or do not know what the firmware or is md5 checksum.
    Sorry to ask these questions, but I'm locked
    Thanks in advance

    Use a md5 checksum generator (there are plenty available if you google it) to get the md5 checksum of your downloaded file then compare it against the correct md5 checksum as shown here;

    Mr. Higgs
    thanks for such a quick response ¡¡
    I'll read on google how it works md5 checksum and I'll use it.
    To install the v10 firmware should I use RKBatchTool - 1.7?

    Another thing, after making http://www.minixforum.com/threads/downgr...only.5218/
    x7 to connect the TV and not see anything, I suppose not have any firmware.
    I install v10 firmware after checking md5 with RKBatchTool - 1.7?
    Thank you and sorry
    (A lot of questions ...)

    Hardware Guru. I owe you big time, this is the only way I could get my MiniX 5 back working after it brick'd randomly and I tested several updates that kept failing, custom and official.
