Tablet Overmax Qualcore 1020 3G - you cannot upload the firmware

Question

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...

Did you follow the manufacturer's instructions?

r0m4n · Answer

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.

Best regards,

You can find the instructions on the manufacturer's website.

r0m4n · Answer

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.

nutergsm · Answer

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

r0m4n · Answer

I tried different combinations and NOTHING

nutergsm · Answer

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

r0m4n · Answer

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.

nutergsm · Answer

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.

r0m4n · Answer

Drivers installed. I also tried this key combination (vol- vol + power). Added after 44 : Thanks for showing interest.

PHUELZET · Answer

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.

r0m4n · Answer

I tried as described well, NOTHING. Maybe the problem is with the operating system. I will look for an older computer. PHUELZET: what did you mean by writing Best regards,

nutergsm · Answer

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

sudido · Answer

The + and - buttons pressed when switching on causes the tablet to start in safe mode. / Without applications installed by the Play store / Unfortunately, you cannot uninstall the search engine application this way. / Launches pop-up ads, sometimes blocks the screen /

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. Installation error keeps popping up. Has anyone had such a problem?

billy1979 · Answer

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?

nutergsm · Answer

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

billy1979 · Answer

Detects device unknown and yellow question mark.

nutergsm · Answer

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

billy1979 · Answer

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.

pakiet · Answer

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.
