2: Run RkBatchTool
3: Plug usb into OTG on unit. Not into Pc yet.
4: Jump pins 8 and 9 with something conducive ( I used a needle ). Pic included.
5: While jumping the pins plug the usb cord into Pc, If you have a good connection on the pins you should hear the "bonk" in Windows and see a blue light in connected devices. You now in MaskRom mode.
If you do then move to step 6 otherwise unplug from Pc and try again till you get the blue light.
6: Choose firmware
7: click Restore and wait for success!!
I have read that nand chip likes pin 5&6, 6&7, 7&8 or 8&9. as jumpers but 8&9 worked for me multiple times. Don't get in a hurry it may take a many tries.
I think that covers it, if not just ask.
