    Hello,
    I have a problem downloading firmware to the tablet.
    I am forced to upload new firmware because I have a virus on my tablet that cannot be removed.
    The tablet itself turns on the WiFi network, if it gains Internet access, pop-up windows with Chinese subtitles.

    Reset to factory settings does not help.

    I downloaded the software from the manufacturer's website.
    The "UpgradeDownload.exe" program can see the device but cannot start uploading.
    I tried different combinations with the '+', '-', 'reset' and 'on' keys.

    Does anyone have a proven solution?

    Best regards,

    Did you follow the manufacturer's instructions?

    I don't know what instruction you mean.

    I downloaded the program, soft.
    I installed 'USBrwSCI-android-usb-driver-jungo-v4'
    I started the program, loaded soft (Qualcore 1020.pac), start downloading, connected the turned off tablet and turned on the tablet by key combination.

    He follows the instructions.

    5. Connect the device, press the RESET and VOL- buttons, release the RESET, the installation will start automatically; release VOL-.

    And here's the problem:
    After releasing Reset, the tablet starts up. No software uploads.

    Hold the reset longer, or do not press reset just vol- immediately.

    How do you connect a tablet with buttons so pressed how is it detected in the device manager?

    Pressing Vol- with the tablet turned off does not cause anything.
    Pressing Reset and holding causes nothing. Release Reset causes the tablet to start, regardless of the Vol- button.

    Added after 15 [minutes]:

    There are no errors in the device manager.
    Immediately after connecting the tablet, "SPRD COM Enumerator" appears, but then disappears.

    At this point, you need to install the drivers and then it should get it. If the driver is already installed, try vol- plus vol + and power.
    If that doesn't work, I have no more ideas.

    Drivers installed.
    I also tried this key combination (vol- vol + power).

    Thanks for showing interest.

    I just finished uploading the firmware for this model. The tablet is already working, it was blocked by a pattern.
    Following the instructions "Qualcore 7022 3G.pdf Update" I had the same problem as the r0m4n user

    The update went without a problem on Windows XP Home 32bit, with both "+" and "-" buttons pressed at the same time and a connected USB cable.

    well, NOTHING.
    Maybe the problem is with the operating system. I will look for an older computer.

    It's easy. Blocked had a tablet with a pattern or pin and could not use it. That's why he uploaded new software.

    The "+" and "-" buttons pressed when switching on causes the tablet to start in safe mode.

    Hello. Did you deal with this tablet? I bought the same dad. He used it several times, and that's how it lies. The annoying thing is that windows were popping up all the time. Today he wanted to use but the message "Sorry, shell application has stopped" popped up. I called the service, they told me that the system has crashed and you need to upload a new one. I pulled out the memory card and now the green android man is lit on the white screen. It cannot be turned off or reset. After pressing the reset turns off, but in a moment turns on again. I tried to follow the instructions but I was already stuck on the USBrwSCI-android-usb-driver-jungo-v4 'installation.

    I cannot connect a device (tablet) before installing the USBrwSCI-android-usb-driver-jungo-v4 'program. The tablet is not visible. Has a damaged system. I have already reinstalled windows in my laptop but the problem persists. I will have to check on another laptop. Maybe the older one will go?

    The device manager does not completely detect the thread? Maybe the USB socket and the tablet is damaged or the cable.

    Well, I gave instructions on how to find and install drivers. Enter the device ID.

    Device ID: USB \ DEVICE_DESCRIPTOR_FAILURE. From what they told me while talking on the phone, I must first install this program USBrwSCI-android-usb-driver-jungo-v4 'to be able to install a new tablet operating system from a laptop. Unfortunately, but I could not install this program on my computer or on my brother's computer.

    What am I doing wrong? I connect the tablet, press reset + vol - the status is: downloading counts down the time, but in progress it's gray - nothing is happening. Finally, I get a message in Progress: Failed: Wait input time out. I tried win7 x64 and xp. I also tried vol + + vol- - no reaction.

    I uploaded the software, but had to do it on the old WinXP system.

Topic summary

The discussion revolves around issues faced by users attempting to upload firmware to the Overmax Qualcore 1020 3G tablet, which is infected with a virus. Users report that factory resets do not resolve the problem, and attempts to use the "UpgradeDownload.exe" program fail to initiate the firmware upload despite following manufacturer instructions. Various key combinations involving the volume and reset buttons are suggested, but many users experience the tablet booting up instead of entering the firmware update mode. Some users successfully uploaded firmware using Windows XP, while others struggle with driver installation and device recognition issues. The conversation highlights the need for proper driver installation and suggests trying different operating systems or older computers for compatibility.
