Yes, i installed the latest command line toolset. Tried nrfjprog --recover. But it says no debugger found because it needs the driver first I guess.

Have you download the latest nRF5x toolset? Have you tried to use nrfjprog to communicate with the chip? Try --recover

I checked Windows Device Manager, J-Link is under Other devices. Did uninstall the driver and rescan the hardware, couldn't solve the problem. I installed J-Link 6.10K. Didn't solve the problem. My other J-LINK debugger is working OK on this computer. Any hints?

I verified the 10 seconds again. The bootload drive does stay there. Not sure why I thought it was 10 seconds. So I put the nRF5x-OB-Jlink-IF (latest file: J-Link OB-SAM3U128-V2-NordicSemi 160212.bin) there. After it finished copy, the bootload drive is gone. I recycled the power on PCA100028, LD5 is solid on and I always get a JLINK drive, but still no connection to nRF studio.

I don't remember if the bootloader should exit after 10 seconds, but my procedure would be to first go to the download section here; www.nordicsemi.com/.../eng-GB

Download the nRF5x-OB-JLink-IF

Start the bootloader mode again, and drag and drop the nRF5x-OB-JLink-IF.bin onto the bootloader drive. Hope that works.
