I can't update the J-Link OB firmware (nRF51-DK)

shaints 
I bought nRF51-DK yesterday.
I installed nRFgo Studio(1.20), Keil uVision(5.15), Softdevice s110 (8.0.0), J-Link(5.00),
nRF51 MDK(7.2.1)

I turned on the nRFgo studio, I clicked Segger 6812......
Then, the studio said that 

---------------------------
J-Link V5.00g Firmware update
---------------------------
A new firmware version is available for the connected emulator.
Do you want to update to the latest firmware version ?

NOTE: Updating to the latest firmware version is strongly recommended.
New features / improvements may not be available without a firmware update.
---------------------------
Yes(Y)   No(N)   
---------------------------

So, I clicked Yes. 
The result was it.

-----------------------------------------------------------------------------------------------------------
New firmware:  J-Link OB-SAM3U128-V2-NordicSemi compiled Jun 16 2015 17:08:23
Current firmware: J-Link OB-SAM3U128-V2-NordicSemi compiled Mar 11 2015 16:29:40
Starting bootloader...
  Waiting for emulator to detach... OK after 179ms.
  Waiting for emulator to attach... OK after 178ms.
ERROR: Firmware update failed.
--------------------------------------------------------------------------------------------------------------

So, I cannot update the J-Link firmware.
What's wrong with me?

Please help me.

    I can confirm that Eugene Yu solution works. So all credits to him! Thanks!

    [...] The issue disappeared after update firmware manually with bootloader mode.

    Here is a quick how-to:

    1. Download suggested J-Link Interface MCU Firmware for nRF51-DK
    2. Enter boot loader mode of the interface MCU (More info here)
    3. Power off the board
    4. Hold the IF Boot/Reset button - keep holding it
    5. Power on the board
    6. The LD5 Led should be blinking (0.5Hz)
    7. You will notice a new drive appearing in your Computer with label: BOOTLOADER
    8. Copy the J-Link OB-SAM3U128-V2-NordicSemi 150616.bin file to the root of this drive - normal copy-paste operation. (The LD5 will start blinking fast)
    9. Power off the board and the power it on again...
    10. You are done! New bootlader installed! Issue gone!
