Did you use the included Driver Assistant?

What keys? A Reset hole?

I installed newer driver I could find on the net (ver 4.1 see attachement).

Concerning the keys I am not sure I understood your question.
The tablet has a micro reset button close to the vol keys. Using the alternative method first I pushed that micro button and then immediately I pushed together switch-on key and vol+ key.

Ok, so Power, Volume rocker and Reset.

I guess this is still a driver issue. Here is a tool to make the ports visible: http://www.nirsoft.net/utils/usb_devices_view.html

Enable also PC sound. One can hear the switch.

To start the tab into flash modues, one can try:

adb reboot bootloader

I installed USBDeview and I also uninstalled and installed again rockchip drivers with DriverInstall but I cannot get to find a LOADER device when I run AndroidTool.

If I boot into the system ABD device is found and if I enter the bootloader for recovery (pushing first reset button and immediately after power-on and volume-up together) after a while again only ADB device is found.
First picture was taken with device after system boot and second picture was taken with device in bootloader recovery.

Looking USBDeview it seems that product id for SoC is 310d while RK3126 should be 310c if I am not wrong.

Any idea to manage the device to be found as LOADER device?
Still thinking is a driver issue?

Thanks and regards.

Usually RK312x is 2207:310c. I haven't noticed 2207:310d, yet.

ADB is active (magenta), so pls test the approach in post #22.

hello OMA
many friends of the Italian forum, report that with your script you are unable to do the root, but only the dump. I always refer to rk3126.
shall we then make any corrections.

Thank you OMA

The system is either full or corrupted. That's why you can nothing push into.

One can also flash back the system.img from the v1.0 build. Copy it on the the external sdcard and try via adb:

dd of=/dev/block/rknand_system if=/mnt/external_sd/system.img bs=4096

using adb roboot bootloader has the same effect as pushing "Switch" button; the device switch off and does not restart into bootloader recovery.
When the device is in this off state (any device is obviously found) if I press power-on and volume-up after few seconds I hear the usb disconnecting (???) and after that if I push the same sequence again the device starts as expected with bootloader recovery.
At the end always no loader device found.

Seems we have an issue with the new ID. I tried to repack a tool-set for it. Pls test: http://crewrktablets.arctablet.com/?wpfb_dl=2700

Use the Driver Assistent and uninstall driver first. Then install driver. Now try the RKAndroidTool to flash the TWRP.

I tried repack, but nothing changes, always "only ADB device is found".

I do not understand why....

Hello,

I have tried to flash this 2 euros tablet (RK3126 android 4.4.4), but I have used a wrong .img and now I have bricked the tablet.

I think I have the right drivers, because mine is also detected as 2207:310d.

I have tried the tool RKBatchTool-v1.8, it has the blue square, and can't do nothing.

I also used the AndroidTool 2.35, that say "Found one MASKROM Device", but when I try to do something says "Match device type failed,stop running!".

Tablet does not boot, but I believe I can enter in flash mode, because windows 7 (x64) detected the tablet has a "Rockusb Device" when I try to connect with UP Volume and Power button.

What can I do to try to recover the tablet?
