DJI Phantom 2 Vision FC200 EGG camera - Black video FPV solution to fix

Hi guys. I want to thank everyone who contributed to this thread. I've had a non-functioning camera for over a year. Following the process you developed, I now have a working camera again.

I appreciate all the work you did with documenting a fix. Hoping other folks find this helpful as well.

Hey guys

Well after some time I have managed to get a successful response from a cam that had no FPV, it’s hard to find what I would call a definitive output on this thread but mine seems to indicate that the flash was successful

I did end up trying a couple of flash files, with no luck but then found a set from I think someone on page 8 or 9.

Only issue I have now is that the camera isn’t transmitting the wifi signal, I can’t see it in INSSIDER, I promised the missus I would be done at 7pm so not had a chance to look further into it, it may be a loose connection when i temp reassembled the boards.

Back soon. Hopefully with good news

@quaddamage

here is the output, but i still cant get it to show up on INSSIDER, it worked before I flashed the board (before i did anything at all, now nothing ??

Has anyone come across this before

I had to tap 5v from the TTL board to TP8, some have mentioned this wasnt needed, but without it I couldnt get Putty to show anything.

Putty doesnt show anything if the board is corrupted, getting into BOOTME mode was fiddly, but once I touched the resistor then putty started showing the BOOTME message,

I tried a couple of different files and in the end the ones that worked for me were called ublp2.img u-boot_prop.img.

You can see from my previous post that using ubootp2.img resulted in No WIFI being transmitted, not sure why.

I have added the files I used to my google drive, here is the link

Meet Google Drive – One place for all your files

Google Drive is a free way to keep your files backed up and easy to reach from any phone, tablet, or computer. Start with 15GB of Google storage – free.
drive.google.com

I hope someone finds this helpful, and I will be doing a video guide to it at some point.

Many thanks to all those who have helped out in this thread, you know who you all are.

Guys, the files I linked to worked fine for one egg camera, but the one shush sent me, the files gave me all sorts of strange things on Putty, in the end I used the files from the vision plus fix and they worked, maybe the camera has a different chipset? Thoughts anyone

Both Vision and Vision Plus use the same chips, no update was made there.

VP software has different configuration though - the flash memory map is different, meaning the NAND is divided into partitions in a different manner:
O-Gs wiki - Structure of DaVinci NAND dump

It is possible that later models of the Vision have that change already - DJI never intended DaVinci FW to be updated beyond factory, so any changes there would have no influence over users.

Hi fellows, I got a stubborn board that is in a bootloop, I cannot get it into a bootmode,when I hook the middle resistor to the tp10, it's mute - wout any output on serial interface. I changed cables, played around with voltages (5V vs 3.3V) etc, without success.
Anyone came across similiar problem?
Cheers!
 
Hi Again, I have the same problem with another board. Both were flashed by me and now the common problem is that they cannot get into the bootmode properly. On normal power up, both spew only this part:
Code: 
 initialization passed!
TI UBL Version: 1.50
Booting Catalog Boot Loader
BootMode = NAND
Starting NAND Copy...
After connecting TP10 and the middle resistor, uart output is mute. Both behaved normally before - "Boot me" could be seen, now not.
Is it possible that flashing uboot and ubl affecter boot mode somehow? Can anyone check this?
Cheers,
Łukasz

I had that, i used the wrong files to flash with, ive done 3 cameras and for some reason they used different files to work

camera 1 ubl1_editedByGaucho.img u-boot_modifiedByGaucho.img
camera 2 ubl1_prop.img u-boot_prop.img
camera 3 ublp2.img ubootp2.img

Not sure why i had to use different files but as i said ive repaired 3 so far. all the files are available on the forum.

I have created a Visual basic tool which is a self extracting archive and will copy all the files needed to your profile and creates a desktop shortcut called NANDflash.exe on the desktop, it has the 3 set of files that I have used
NET FRAME WORK 4.5 MUST BE INSTALLED FOR THIS TOOL TO WORK

If anyone comes across this thread and wants to do the repair themselves I have written a video guide and built a tool to do all the flashing part, you will just need to buy the TTL to USB adapter to do the repair.

I was waiting for this for a long time, friend of mine who passed in the meantime gave me his crashed p2v few years ago, after I manage to fix the p2 suddenly camera stopped working ... Hope that I ll be able to repair it with this solution. Thank you for all the efforts!

Okay, I decided in the end that because of my essential tremor I would not attempt this FC200 repair myself...the soldering points would have presented a difficult situation given the small contact points on the 3rd PCB.

I am pleased to say that through this forum, Turner reached out to me and I availed myself of his repair service and my P2V /FC200 is back to its original FPV working condition.

Great service! Anyone who wants the link to his FC200 service, PM me and I will send you the link.

yeah i just read and re read and read again the instructions on the wiki and its well over my head, guess this board isnt getting repaired
