The text of the instructions from the article on HabrГ© on the MK908
In MK908II everything is absolutely the same !!! :

First you need to put the MK908 in firmware update mode. For this:
1. Remove the microSD card from the device, if it was inserted
2. Connect the supplied USB cable to the OTG port and the other end to the computer. The MK908 will turn on and Windows will detect the new device. No problem, we need the device to be turned on.
In USB3.0 do not connect! USB3.0 Rockusb doesn't work
3. In the folder with the firmware, find the ROM_FLash_Tool.exe file and open it
4. “Found RKAndroid Mass Storage USB” should appear below.
If there is no such inscription, do the following:
a) USB Storage option enabled in MK908 settings
b) The debugging option is active in the system settings (USB debugging)
5. When the “Found RKAndroid Mass Storage Us” message appears in the application, click the “Reboot to Flash Mode” button.
6. Wait 10 seconds. MK908 should reboot and show a black screen.
7. If the device has not rebooted to the firmware update mode - repeat steps 2-6 again.
To exit firmware upgrade mode, simply turn off the power. The next time you connect, the Mk908 boots up normally.
If you are unable to enter the firmware update mode from the Flash Tool, you can try to enter the manual mode.
1. Disconnect the USB cable from the MK908
2, Next to HDMI there are 2 holes. One of them is the blue activity indicator, the second is the reset button. Hold this button with a clip.
3. Hold down the reset button (the hole near the SD card slot. Press with a paper clip)
Connect the USB cable to the OTG port of the MK908 and connect it to the computer.
In USB3.0 do not connect! USB3.0 Rockusb doesn't work
4. Windows will play the sound of detecting a new device, the activity indicator on the MK908 will not turn on.
5. Now you are in firmware update mode. Now you need to install device drivers.
Installing a device driver:
1. When we hit the firmware update mode, Windows will detect one unknown device.
2. Open Device Manager and select unknown device.
3. Right click and select “Update Driver” (“Update Driver”)
4. In the dialog, select the item to search for drivers on the computer. Click "Browse"
5. Go to the folder with the firmware, find the drivers folder, select the folder with the driver for a 32-bit or 64-bit OS
6. Select a folder with the required version of Windows
7. Device driver installation should occur.
8. Restart the computer and the MK908. Download the MK908 in firmware upgrade mode by following the instructions above.
9. If you did everything correctly, the FLash tool should show the message “Found RKAndroid Loader Rock Usb”. If this message does not exist, then the drivers are not installed and you need to repeat steps 1-8.
Now that we are in the firmware update mode and the drivers have been installed correctly, you can proceed directly to the installation.
When updating the firmware, ALL user data is deleted. If necessary, make a backup.
When installing, you can choose one of 4 options for installation:
1 gigabyte data for applications (default setting)
2 gigabytes of application data
4 gigabytes of application data
6 gigabytes of application data
To change a parameter, click on the parameter item, enter the folder with the firmware and select the required file.
You can also choose the core 720p or 1080p
Firmware:
1. In the flash tool program, click "
Erase NAND (IDB) ". This item is required!
The progress counter should reach 2048. If it has not reached this value and the message “erase success” appears, it means that the data has not been completely cleared and the formatting procedure should be repeated.
2. Press the "
Flash ROM "And wait until the process is complete.
4. After the firmware, the MK908 will reboot.
The first power-up after the firmware update takes longer than normal download. After a full load, wait another 2 minutes for the system applications to make their changes to the system.
