[Q] Rockchip Tablet - Android Q&A, Help & Troubleshooting

I have a generic RK 2906 Tablet and I've been flashing different ROMs, Unfortunately I flashed something, not a ROM from the android tool folder. The tablet screen is not working anymore, and my computer can detect but can't recognize the device anymore knowing that I installed the correct drivers. So I guess I changed the usb function of my tablet into something else,. How can I restore it?
Another thing, In device manger, why is my tablet (unknown device) is loaded in 'Universal Bus Controllers' tree and not in 'Other Devices' tree.

O'lofer C740 wrong firmware.

Hi Guys,
I have a O'lofer C740 tablet. It is a locally branded chinese tablet, similar to the LY-F1, but with some noticeable differences. In an effort to make the device more usable I did try to reflash a different ROM. The procedure was flawless with LiveSuit, the device boots up, but the touchscreen or the touchbased buttons don't work. Touchscreen registers a touch once in 20 times. So,
1. Is anybody able to help out with identification of this device (I think it is not LY-F1, but similar). Pictures:

Please note the differently places SD slot.
2. Is there a way to fix the touchpad? Different drivers/calibration?

What am i doing wrong
probably a driver issue
Domdo said:

Click to expand...
Click to collapse
According to this everything was well
Maybe USB not responding as MTK usb or preloader mode.
from experience, it is a driver issue with Windows 8-10 or when you connect an mtk device tap both power and vol+ (vol-) at the same time

Fastboot driver?

ADB works when booted up but not when im in fastboot,

Fixed, for some weird reason fasboot devices doesnt show anything but I can still fastboot flash
please provide link fasboot/adb usb driver for poco f3
unzip this file and press win+x device manager go to android item (sure it's with an exclamation sign), then select update driver, choose location or folder and go to the folder that previously you unzipped.
I searched all over web to find any driver, tried all and with this my search was over.
