Try to flash again, be sure to use Restore button in Rockchip flasher.

Also use a good quality USB cable.

Can you try to flash again the JB firmware ? If you have a desktop PC, it's recommend to connect the USB cable to the ports on the back of the machine, not the ones in front; also try to avoid using USB 3.0 ports.

Maybe try on another PC if possible ?

That can be a failure of the NAND flash memory, which isn't good Confused

You may also try RK_Android_Tool (v1.35) from our Rockchip flasher page.

Once your device is detected (it works the same as Rockchip batch tool), just push the Erase IDB button, when erase is finished try again in Rockchip Batch tool.

 

I don't think you can repair a damaged NAND flash, you'll have to return/RMA your tablet to the manufacturer.

Do this l, it worked for me. Turn off the tablet. pres volume down then power button and keep pressed until screen is on. Then press first power button and volume up button above to enter recovery mode. then do a wipe clean or something like this(i dont remeber for sure. after that enter 4 and 5 points of menu shown there. it should work. I dont know if this helps but i putted the ics firmware on sd card. Try.

After some time of testing, my conclusions about this firmware is that it's better than ICS: faster, smoother, easiest. Only PROBLEM: tablet is booting only with charger in. I looked up on another topics and found same issue and fix for it: the idea is to change services.jar file in sistem/framework folder, with one given by a link. I did it and the booting was fixed, but tablet speed was slown down... And I came back to ICS.
Fixing this problem will make it perfect.

Thanks for the tip, I'll have a second look if I can make some improvements in the firmware.

Cheers.

If the tablet is just sleeping for 10 hours consumes 10.8 percent - is this normal? I'm afraid that I have a marriage with the battery, or cause in the firmware. This was observed at firmware with google play and now this. If you simply use the tablet, to climb on the menu and so on. Eats 1 percent to 1.5 to 2 minutes, this is normal or not?
