If your ENYBOX Clone failed while flashing or never turned into blue led after pressing the turn-on button, you should bring your device into maskrom-mode and flash the stock/orignal firmware.
A sign for a bricked eny-clone is a poping yelow device symbol like this, hangs at 100% testing:


-You need the right driver for eny-clone like my one here < -> original enybox here
There should be no warning in windows device manager!
-open your box:
2 screws under the rubber-flats, then clip of the bottom panel
2 screws hold the mainboard
-connect only usb, no power!
-start Rockchip Batch Tool v1.7 as admin ->Source or here or here or just google it
-PIN the 7 & 8 connectors of your nand (here cheap FORESEE):

-Then when you did this, connect the power cable:

-Rockchip Batch Tool v1.7 should show you instead of an green device label a blue device label:

-If is is blue you can simply flash yur stock rom again

I hope I can help you with that.
