    @trananh: I found a small trick could help MCP 3.7 works.

    First make sure you have flashed the firmware located in C:\Program Files (x86)\Nordic Semiconductor\Master Control Panel\3.7.0.8488\firmware to the dongle you have. Then click File -> Option -> Serial port , selcect Show all serial ports After that you should be able to select the COM port matching with the dongle virtual COM port. Then you can use it.

    Regarding "Porting the new bootloader from SDK v7.0 back to SDK v6.1": I meant you can copy the bootloader for SDK v7.0 and use it with SDK v6.1, some modification needed. But I think it should not be too complicated.

    I try this but it not work

    The first time, I conneted but when do DFU, MCP say "Failed to find device. You may want try again"

    But after that, I can not start discovery device. MCP say "Received error: BTLE_STATUS_CODE_COMMAND_DISALLOW"

    @Trananh: What did you try ? to port the bootloader or to use MCP 3.7.

    If you use MCP 3.7, make sure you have flashed the firmware came with the MCP v3.7.0 as mentioned above.
