My Osmo has decided not to power up for more than ten seconds before going limp and displaying a solid red light. I have tried the method of holding the trigger, record and power button and that allows me to keep it awake to check firmware status which comes back as "unknown". I have tried flashing the latest firmware (and previous firmware versions) without success. Once 99% progress has been made the Osmo powers down and displays solid red light again, even if I leave it for 20mins and I get an update failed notification. Here is the txt log from the SD card. Any help would be much appreciated.

#solved Ok, after spending a good few hours on this I managed to get it to complete the update. I had the Osmo plugged in to a Phantom 4 battery with the adpater and dummy battery from DJI and it failed everytime at 99%. After having tried every old firmware and latest firmware for Osmo on DJI site I tried with the Osmo battery and it completed the update and now works again with both the normal batteries and the dummy battery connected to a Phantom battery or mains charger. Hurrah, I thought it was going to need to be sent away for a fix!
