1. Connect the tablet to the USB port of the computer
2. Run the RKBatchTool.exe program on the PC
3. Perform a tablet shutdown operation by pressing and holdingpower button , before the shutdown window appears on the screen. Confirm shutdown.
4. In fact, the tablet will not turn off, but will reboot! Therefore, as soon as the tablet screen goes out, simultaneously hold down the volume button on the tablet - andpower button . Windows operating system will detect the new device, install the driver (located in the folder: Rockusb)

It will be needed for those whoAdb drivers not installed or the device is in a half brick state.
BUT)
1. Click "reset".
2. Clamp "vol-" and "on" for a few seconds. If the firmware drivers are installed, then the box inRKBatchTool turns green (you can press "vol +" to wait for RKBatchTool pink box and press "switch" - the tablet will reboot into the firmware mode).
If a robot appears with a ripped belly, then we start with item 1
B)
One moreoptionwith rewriting in the drivers.

Use this way of flashingonly as a last resort, for example for splicing.
1) Make sure the tabletfully charged(In the recovery there is a recommendation to flash the tablet with the power connected).
2) Download the firmware and save it to your desktop.
3) Extract the .img file -heremore
4) You will need to copy it to your desktop and rename it to update.img
5) Save update.img to the root directory on a microSD memory card
6) Insert the microSD card in the off tablet
7) Press and hold the volume up button and the power button until the logo appears. Release both buttons. The launch of the update system occurs and simply when the map is installed with update.img. Not always there is a clear triggering of a combination of buttons to call up the recovery menu, so you will probably have to play around with them. Or after the appearance of a recumbent android, you must press "Vol +" (volume up) 2 times (quickly)by poter06
8) The Android logo with a red triangle will appear! Pressing the volume and power up keys again brings up the recovery menu.
9) Use the volume key to select rkimage update from sdcard (last menu line), then press the power button to select it.
10) Firmware update will be available.
At the end of the firmware, the recovery menu will reappear. Choose a reboot tablet. All firmware upgrades completed.
For those who are stitching from the card (in any way) - after the update.img file has been dropped onto the card, check its hash sum (for example, md5), compare it with that on the PC. To be sure that the file was discarded intact (right on the tablet md5 can read, for example, root explorer).
Custom firmware may produce an error checking the file, forcing to use another method.
