How do I replace the mBed bootloader with J-Link's on nRF51 Dongle so I can flash the IC with nRFgo Studio again?

Download it - plug in holding the button - that mounts the bootloader - drag the image you downloaded to program it. When it's done unplug/replug it.
I would suggest then running 'jlink' or 'jlinkexe' from the command line after you've done it as the firmware probably needs upgrade, it changes reasonably often.
This is all in the user guide by the way
Thank you. Minor comment: by 'it' he meant J-Link OB image which can be downloaded here: www.nordicsemi.com/.../38679
