• Here's my amended steps that worked for me.

    STEPS I FOLLOWED

    1. I found NRFTOOLBOX on the Android Playstore and installed it. (DFU Library version 1.10.3)
    2. I downloaded the latest firmware distribution: 2v11_banglejs2.zip
    3. I poked the DFU button in the NRFTOOLBOX.
    4. I poked the SELECT FILE button
    5. Selected the Distribution packet (ZIP) & poked OK
    6. The Search this phone page appeared and displayed No items.
    7. To find the download file I poked the This week button and espruino_2v11_banglejs2.zip file popped up. I touched the app to select the file.
    8. That took me back to DFU page. I held the fob down until the === started, then released the fob.
    9. I poked SELECT DEVICE then SCAN and selected DfuTarg. The watch screen displayed CONNECTED
    10. The download began and the progress bar on the phone let me know how far it had gone. When it finished the watch rebooted into the new firmware.

    NOTE: In step 10 I expected to select the BT name of the watch but in Dfu mode (that's what it goes into when you long-press the fob and release it before the ==== stop marching across the watch screen) it switches to DfuTarg instead.
