[HELP] MK809iv (RK3188) bricked!

I have a MK809iv (RK3188) TV stick, it got bricked. I searched the internet and tried many methods to recover it, but failed, please help if you know a better solution.

I used RKBatchTool to restore it, and got a blue square, but after I click "restore" button, it failed at "download boot fail"

Code:

---

22:30:27 985        **********Restore Start Total<1>**********
22:30:27 985        <Layer 2-1> Download Boot Start

I also tried RK Android Tool, my stick is loaded as "Found one MASKROM Device". I played around the tool, but every time it failed at the same reason "Download Boot Fail".

I have no ideas, anyone please help!
