    Of course you should firmly plug the 2 pcb before to power it on for flashing.
    It's like the memory in your case is protected...
    You must also be sure that no metallic part touches the pcb in unwanted way so that no wrong electric contact is created. I placed tap over welded points otherwise, once reinserted in the aluminium chassis it makes short to ground.

    The two boards are well connected...
    I made sure they worked well (include even connecting to the lb ground)...
    do you think I should do the procedure with it firmly mounted on the aluminum housing?

    No but don't leave it powered for long time cause the chip will become hot and may stop in order to do not get broken.

    Yes. I just turn in the time it takes to make the command, and since it does not work, I've already disconnected from the power ...

    as for the problem you are presenting, do you have any idea what might cause it? I have done all the procedures listed in the forum ... including that of executing the command and reconnecting the unit, without using ctrl-c. But nothing worked ...

    I have got the exact same problem as wtercato, I also get the corrupt message from the air system, and none of the methods here work. The log is pretty much the same as wtercato's, including the nand protected stuff.
    I am on Win 10 64bit, but unfortunatly I dont have any access to other machines right now.

    I still have this problem, and I could not solve it. Already done the procedures on other computers, including 32 bits. But nothing solved ... I already checked the wires and connections.

    I am waiting for other people with similar problems for various tests in order to arrive in a solution.

    The gaucho and all of the forum has already helped us a lot!

    Hi Gaucho,
    The solution proposed by you for the lightbridge can be applied to P2V +? I stopped using it for a few months and it does exactly the same thing, it does not transmit video but it does the telemetry.

    Thanks for your help.

    Hi Gaucho,
    I'm trying to repair a ground unit.
    I followed all the steps but the process keeps on looping with the following information:

    Waiting for DONE...
    Target: UART Receive Error
    Target: Starting UART Boot...
    Target: BOOTUBL

    Waiting for SFT on the DM36x...
    Target: Starting UART Boot...
    Target: BOOTUBL
    BOOTUBL commmand received. Returning CMD and command...
    CMD value sent. Waiting for DONE...
    Target: DONE
    DONE received. Command was accepted.
    Sending the UBL image
    Waiting for SENDIMG sequence...
    Target: SENDIMG
    SENDIMG received. Returning ACK and header for image data...
    ACK command sent. Waiting for BEGIN command...
    Target: BEGIN
    BEGIN commmand received.
    100% [ ]
    Image data sent...




    Any suggestion?

    Thanks

    Hi all,
    For those of you with Phantom 2 Vision+ Plus quads that are suffering the blank screen in app issue - no FPV, but good telemetry data. I've successfully revived my wifi module using info from this thread (big thanks to Gaucho, rmhome, andrew_by and others).

    I packaged it up into this tutorial: DJI Phantom 2 Vision+ Plus Blank Screen Corrupt NAND fix

    I hope it helps some people revive their wifi modules too. Good luck and feedback on my tutorial is welcome.

    Gret work okstuv!
    Can you tell me how to connect the power with this converter? Should I let the jumper to 3.3v and connect another cable to the 5v output?
