fail to flash bootloader, got idb failed

[yushikr7]

Hi,
I got 1 clone unit minipc with Rk3066 processor, 1gb ram, 4gb internal storage.. The problem is everytime i want to flash a rom using rkbatchtool, i got idb download fail.. When i tried flash one by one ( system, recovery, parameter ...... ...) All succeed except the bootloader.. Is that means the bootloader is locked ?

Hello,

The Best way to get around is to bring your Device in the Mask Rom Mode.
You do this by Shorting Pin 5&6 on the Nand Chip when the Device is in Boot Loader Mode.
Then you can Reflash it with your Firmware.

Hi Neo, it's already a hole for reset. Usually , i push this button while connecting to my laptop.by doing that the rockchip devices could be found.. Is it different? I can flash all in the finless rom except the bootloader, and i can boot the android normally...

By making a Nand Reset the Device going to Mask Rom Mode.
With this all can be rewriten by Flash Programm. Is like a Total Reset of the Nand Chip.
