Try putting it in Mask ROM by shorting NAND pins 8-9 while connecting the device's USB-OTG port to your PC.

Ouch the dreaded -T version chip...

NAND chip is the big one with multiple pins located below the RK3188-T CPU. Pin 1 is in the lower right corner. Count from there to 8-9. The
spec sheets for different NANDs differ (look yours up) . You want to short CE and RE
