many thanks to all those involved
Thanks for all you do for the P3!! It is a great drone so few still dig deep into repairs on it!! Parts are getting hard to find :( Hope many find this useful as time goes on... :)
Cannot tell you how much of treasure this type of info is.
Thank You !!
Subbed
Belled
Pure perfection 👌 Thank youuu!!! 🍻This flash tool helped me a lot! Using manualy CMD didnt worked for me 😂 (CH340 FTDI used)
Thanks for the comment, glad it helped
This is great , thanks for replying to my email Justin. I’m subbed. P2V+ repair worked flawlessly so fingers crossed for this one. I take it the board is the same one? Does the jumper need moving over? Cheers
No use the same 5v as with the other one.
@@FlymyPhantom thanks again
Thanks for the tutorial, have you seen a situation where it worked initially but then stopped working again?
I completed the repair, powered up, received a video signal, powered down, installed the props, placed it outside, powered up and the Gimbal Disconnected message re-appeared. I repeated the flash process, but all I see it a "no video transmission" message, not sure if it was there when the problem started or if this is a new issue.
Any suggestions?
Thanks again
I did the procedure with ft232bl but without success putty does not generate any messages could you help me?
When I flash, it gets stuck on the text "target". Please help me
Hi
i need more info than that, first off always double check your wiring and make sure it is correct also make sure you are using the correct type of TTLto USB adapter, please send screen shots to flymymavic@outlook.com. please note i am on holiday so may not reply straight away
Thanks a lot for the tutorial I made it and successfully recovered the image, but I lost the gimbal orientation, it is -25 degrees to the left there is some methode to correct it?
try a gimbal calibration
@@FlymyPhantom Thanks for your quick answer, Ill tryed but is not corrected, I remember that it is calibrated in production, beacouse is a magnetic detector and need to put the value in some memory probably the same I flhased and the new dont have the same information in this point, I am not sure of that. Some times ago I read about it and I remember that exist a cheap that is programated during production.
Excuse me I have discovered my mistake I have tightened the screw of the axis outside the chamfer.
I take this opportunity to comment on another mistake I made in case it could have happened to a novice like me. I couldn't communicate by serial until I changed the Rx and Tx cables and everything started to work perfectly. Thank you very much for your help.
@@ferminsalazar9742 yep that will do it, glad it's sorted
Will this work for the boot loader on a Inspire camera module with a DM368 or the HDMI GL658 module with a DM368
Visit wiki.dji-rev.com/ there is loads of info on there
Just wondering if this nice app would be easier . I’ve seen the manual method and not sure it’s my skill set
@@broughamjb if you email me at flymyphantom@outlook.com I can build an app based on which instructions you want to follow
i cant get it to say bootmebootme i have 5 boards and none of them do it can you advise please? great vids BTW :) thanks
It’s those 2 tiny pads, I sometimes have to try a few times to get them right. I ended up soldering one wire across the 2 pads. Make sure the TTL board is wired correctly as per the pictures as well
@@FlymyPhantom thank you so much for all you do :)
I can not get it to say bootme in teraterm or Putty it just goes through a chain of computer language forever long I let it run before I close it out. It is read on the correct serial port and I checked wires a couple of times. Can anybody tell me why? this board went bad by sitting for 5 months without use.
You need to make sure you jumper the tiny 2 pins together and to the 3v, it’s booting up (the long repeating text) so it’s definitely not in boot mode
@@FlymyPhantom Thanks so much for the quick response. I love all the details you have done on this subject. I searched for days to finally come to this post that made it more easier to understand and everything you need to do this. I really thought I had the two BT pins soldered together well and connected to the 3.3v pin. I soldered across the two pins. I will resolder again if you think that is what it might be. The board did bring up everything I needed to fly before i took it out because I did not have live view. I could take pictures and video. The drone was not used for about 5 months and this happened. So, I would not think it would not be a burnt out chip. Just a little trouble shooting when I would connect the usb-TTL module it would start the computer language on terterm and if I pulled the 5v connector off the module it would stop. I did this for the ground and also for TX and RX and each time the computer language would stop when I pulled the connector off. So I feel like those are good connections other than knowing the 3.3v is shorted. Again, thanks for your time and help.

One more question, will I have to flash with new firmware after I reinstall the board and power on?
No mate
@@FlymyPhantom The board I have cannot be flashed so there must be a chipped burned out on it. I have tried everything from re-soldering the wires numerous times to running separate 5V to the board. My question is I cannot find a new or used or reflashed board anywhere other that then a option on ebay coming from China! Is there anybody i can buy a board from not having to go to China?
I get the invalid host when I try to run the program any thoughts
Hi thanks a lot for this tutorial, I try it and finally the message programing successfull but not recover video signal, I realised that a block was wrong during flashing.
I paste the message.
->"Target: Erasing block 0x0000000A through 0x0000000A.
Target: Writing header and image data to Block 0x0000000A, Page 0x00000000
Target: Write verify failed, skipping block!"
And other strange messages.
-> "Target: DONE
DONE received. Sending the UBL...
0% [ ------------------------------------------------------------ ]

->"SENDIMG received. Returning ACK and header for image data...

May be the NAND chip are wroken?
If you think that it is the case, would be posible to solve change the chip MSIC XY30LF1G18AC-XK1?, or it is not enough?
Many thanks for your support.
Yes the chip is fried and so won't take the loader program, the only way is to replace the chip which would mean flashing 3 different images which is beyond my scope of expertise
@@FlymyPhantom thanks for your quick answer, so if I change the chip the program is not enough to flash completly the chip?. Isn't it?.
@@AntonioGonzalez-oj1zy no it's a complicated process a search phantompilots forum for advice
@@FlymyPhantom many thanks, I have asked in the foro.
