Firmware flashing stuck at 62%

I reverted back to ver 1.00.0000 a while back waiting for the release. Now I am using NLD Mod Client to upgrade to ver 1.00.0100 because Remove NFZ wasn't working on ver 1.00.0000. Now its stuck at 62% upgrading to ver1.00.0100. It rebooted a few times but now just sits at 62%.

Did you try and reboot your computer. Mine seemed to hang as if the computer's cache was full. A reboot of the computer seemed to work for me.

Don’t worry, just relaunch NLD and you’ll find yor bird flashed.

Well I'm a little worried...

Restarting the app, it just kept telling me to plug in the usb. It was not seeing the aircraft. I started Assistant and it saw it and gave me the error message that some modules had mismatched firmware. I allowed it to fix it and it seemed to finish the upgrade to ver 0100. The NLD app sees it and shows firmware 0100.
But now the Aircraft will not connect to the RC. I have tried to use the GO 4 app to try to resync the controller it but it will not find it.
I have tried to remove the NFZ and it keeps halting on an error. Sometines shortly after the magic bullett and after that near the beginning.

Now you see why I am getting a little worried. It won't do what it is supposed to do and now I can't even connect my aircraft to the rc, I'm completely down....

I used DUMLdore to get the aircraft back to ver 01.00.0000.
I need to reread about syncing the rc to make sure I'm not missing something. Both the aircraft and controller show firmware 01.00.0000 in Assistant.

Need help....

I have also tried it on a laptop. Right now my main concern is to get reconnected to the RC again.

Need help.  Trying to rollback firmware on Mavic 2 pro but firmware upload fail the last ten trys.  What am I doing wrong.  Please help.

hi, do u've got any alert popup of error ?

you can try to flash the firmware to current 400 verison via DJI GO 4 app, and than you can downgrade it to 100 by using NLD, at least it work to me.  better reboot ur computer before use NLD to downgrade or patch NFZ.

Thanks for the replies. It looks like I need to start a ticket on this. I have been trying everything the last couple of days. I have tried three different computers.
What I have noticed is that when the AC reboots during upgrade/downgrade it loses proper usb connection and shows a driver problem and does not re-connect after the reboot.  Even Assistant can't update because it errors out. I have never previously had any problem upgrading/downgrading or AC, RC connection problems before....

My big concern is that since I first tried using NLD my AC and RC will not connect and I can not get it to rebind no matter what I try. I can not use Go 4 as the aircraft will not even connect to the RC to access it. I have spent over a dozen hours the last couple of days just trying to get my AC and RC communicating again.

This has been a very bad / scary experience so far. My M2P is now unuseable....
