Mavic Pro Platinum destroyed after firmware downgrade

[Danielbrauer]

I need your help, please.
I tried to downgrade the firmware of my Mavic Pro Platinum with DUMLdore. But the downgrade failed.
Now I'm not able to connect the device with the USB-Port. The Computer doesnt't recognize the device. When I start the Mavic only the red backlight glows.
I tried to connect with DUMLdore => Serial port not found. Reconnect and restart.
Similar with DJI Assistant 2 => no connection possible. I also tried it with the Nolimitdronez-App => Connect Device to USB.
Is there any possibility to repair it or can I throw it into the trash?

Thats sometimes the problem with using DUMLdore, sometimes it works, sometimes it paralyzes your drone until it can be reversed.

Worst case is that you have to buy a new core board. You dont ever have to throw it in the trash!

Sounds good. Core boards are offered at ebay for 175€.

you might want to try with earlier version Dumldore,then reflash original fw,then downgrade 1 fw version at a time until you get where you want

For my windows 10 version 1809, dumldore 3.0 or above can not run when mpp is connected. Only dumldore 2.14 still works fine.

My mavic is back in life.
Thank you so much.
DUMLdore v2.10 was the solution. After some tries I could connect the device to my computer and update the firmware. (I used Windows 7 x64)

Dumldore version has nothing to do with it, it's just the many reboots, it's known that in this state several power cycles will likely eventually bring it back to life.

@Thunderdrones has a trash can if yours is full

Glad it worked out for you. I can only imagine the bad feeling you got when you thought that you had broken your drone.

Happiness is when things turn back to normal.
