Tolino Tab 8 doesn't boot - recovery mode not working - how to flash

    I am having problems with a android device. Namely Tolino Tab 8

    It does not boot.
    On start the error message reads
    "Secure Boot Violation - Invalid signature detected. Check secure Boot Policy in Setup"

    Then I can't do anything but turn it off again.

    When I try to do a hard reset / enter the recovery mode via VolumeUP+PowerOn there is no difference. It behaves like I just turned it on with the PowerOn Button.

    So I want to flash it via Dnx Mode (VolUp+VolDown+PowerOn). That's the only action I can perform on this thing.
    I downloaded some android 5.0 recovery package from medion.com but on windows and on ubuntu I get error messages because of fastboot (on windows it says "fastboot.exe wrong file or filename" on ubuntu "bash: ./fastboot: No permission")

    Can anyone help me with proper instructions on how to flash the thing? Somehow I am too dumb to find it by myself. Sorry.
    Thank you very much for your time and every effort :)

    What happened? How did your device get to this state?
    what happened? how did the device get this way? just happened? randomly? were you trying to root it?

    there really is not much info on your off brand device as is with most off brand devices

    also i have no idea about medion.com which i looked into and it looked more like an online store similar to amazon.

    i have no idea what an "android 5.0 recovery package" is. is this a custom recovery?

    i would stop right there and not mess with fastboot unless you know what you are doing. fastboot commands along with adb commands can be used to flash firmware updates as well as custom recoveries. however, they are very device specific. so if the files you are using are not made specifically for your device, you need to stop and not continue along this path.

    you will need a firmware update from the manufacturer. unfortunately i could only find the tolino tab 8 on amazon and nothing else. there is also a tolino ereader as well....but that's about it. i would just throw the device away and get something that is not a cheap off brand device.

    Thank you very much for your respond and your time spent on my problem!

    I bought the thing in that state. I have no idea what happened. When I went home I was suprised it couldn't boot.

    On the medion.com thing: I think those are custom recovery images of android versions, yes. I just picked a thing I imagined would fit (KitKat. 5.0). I was not aware it had to be so specific for the device.

    So it's not possible to flash this thing? Would the manufactorer give me the Firmware by any chance?
    shoot... I just bought the thing. That's unsatisfying

    Where did you buy it? Online? Did you buy it used? If it was bought as brand new, you should return it. If you bought it used, that's the risk you inherit when doing so. I will never buy any electronics used unless I know that it works or I can return it easily.

    2 problems: It's a generic no name brand tablet so there is very little information on it.
    Second, it's an old tablet so anything you may find may be outdated (custom ROMs, etc)

    Good luck. Sorry I couldn't find anything useful and some of the links that came up looked sketchy.
    Even XDA didn't have anything except questions.

    Thank you for your responses!
    I want to contact the brand for this, but I still don't know what I actually need.

    My questions are not quite answered
    Could you tell me in what form I need the firmware? (what datatype? like the wrong android version I had with flash.sh/flash.bat?)
    And then tell me how to flash it? There must be tutorials for this...
    As I said in my initial post there is a basic problem with fastboot and I don't think that's because of the wrong android version.

    FYI: I bought it second hand labeled as defective. Battery was dead and the seller couldn't tell what the problem was. I thought i just would do a hard reset and the damn thing would be fine, but as it seems I gambled and lost.

    @Milo Williamson I corrected the title :D Tolono is very small.. what a coincidence

    the problem is that manufacturers use different utility programs to flash firmware updates. for instance samsung uses odin. there is no generic firmware for android. so who knows what format the firmware update is in.

    sorry man, i think you are sol
