Stay cool. I don't know how you got an softbrick. But take a coffee or an beer and do this:

 

1. Push the reset button with a thin stick so you can hear or feel a "click".

2. Start the RKbatchTool on your computer and load the firmware.

3. Hold and keep volume+ on the device

4. Connect the device to the computer via USB

5. Hold the power button until the RKbatchTool shows "green".

6. Choose RESTORE in the RKbatchTool

========================================

If this does not work do this:

1. Push the reset button with a thin stick so you can hear or feel a "click".

2. Start the RKbatchTool on your computer and load the firmware.

3. Start Oma's RKandroidTool (post #1) 

4. Hold and keep volume+ on the device

5. Connect the device to the computer via USB

6. Hold the power button until the RKbatchTool shows "green".

7. "Erase IDB" in RKandroidTool

8. Choose RESTORE in the RKbatchTool

========================================

If this does not work do this:

1. Push the reset button with a thin stick so you can hear or feel a "click".

2. Start the RKbatchTool on your computer and load the firmware.

3. Start Oma's RKdevelopeTool (post #1) 

4. Hold and keep volume+ on the device

5. Connect the device to the computer via USB

6. Hold the power button until the RKbatchTool shows "green".

7. "Erase ID Block" + "Erase All Blocks" in RKdevelopeTool

8. Choose RESTORE in the RKbatchTool

 

MOST IMPORTANT IS TO STAY COOL.

I am 100% sure you can reflash your device again to make it work. You can not destroy a Rockchip device easily.

my jxd repair. has the stock firmware. but I can not install this rom. following the steps of the file "txt" always marks error. You can upload a video tutorial to install it? or the file is corrupt mega?

him down twice and I always mark error.

Thanks in advance

@ alighiero

Nice to hear that your device is running again. My files are not corrupt. But I recommend you to stay on the stockrom or to flash Maetels rom again which you were happy with.

Maybe you have a T-model and maybe Omas firmware does not work with it ?

you have to remove the chip and there JXD alongside the pad. connect via USB and hold the Volume Up botton. with some metal then you do a short pin 8 and 9. and ready the PC recognizes it immediately.

almost 95% of the check rom gives me the error. as I enter the recovery menu after flashing this firmware? you pass me the link of the rom WebClaws? please the best of the Rom.

Sorry, i don't get it.

- Connecting via USB => Check
- Hold Volume Up button => Check
- Remove Chip (sdcard) => Check

What do you mean by "do a short pin 8. and 9."?
