lightbridge firmware PROBLEM (and solution) - firmware version not found by dji assistant tool

[2008jiayu]

Can you post some hi res pictures of your device? Just for curiosity

we never can be going to the dm365 using comxx,phatom 3pro bsel connect gnd ,**** dm365 a11 a12 connect ground,to solve the problem only use factory mode wedonthave the tool

who can find another way to do this

who can find another way to do this

i think it is usb canbe used todo this how

I cant find the BTSEL ，it maybe have being controlled by stm32

Hi, The red circled here BTSEL and 3,3V, I've gone through all the flash and yet not have good p2 vision+ because they do not have wifi video black screen I can not put a good img file

Did you found bsel? You could try with BOOT0 pin that I see in your picture. Do it at your own risk. Did you solder the internal serial port? If yes you should see BOOTME repeated many times

Since I burned up my previous module by using 2 power supplies (USB and 12V) I bought a "bad" p2vp wifi video transmission module on eBay and successfully reflashed it today. The main difference was that I didn't hook up 12V from the quad to the unit - instead hooked up just 5V, GND, UART TX, UART RX and shorted 3V to BOOT on the board. After a few times hitting CTRL-C when it kicked out to "Boot me" in CMD prompt and kicking off the DM36X process again, I got the following result:

I haven't rebinded it and confirmed that all functionality is back, since I'm waiting on a new camera. Once that comes in, I'll post the results net weekend. So far it look good. If anyone sees issues in the log, plx let me know. At least nothing burned up this time

hey, could you walk me through the process from start. i have the wifi module (green) and the video module (black) with the enclosure, with all the cables and the interference board and 2x RE700 repeaters. my P2 is with DJI service @ repairs. I also have the TTL board.

would be great, if I succeed I create a video and put it to the youtube so everybody can follow.

Did you found bsel? You could try with BOOT0 pin that I see in your picture. Do it at your own risk. Did you solder the internal serial port? If yes you should see BOOTME repeated many times

Is it possible to read nand content from working circuit, and after upload it to another (not working) one?

Yes
Does the working unit have the the internal serial port soldered?

It is also possible to get the file from dji and decrypt it. Read this thread, at the beginning

bin in this script is not good to do it but then nothing in either boot

I can not find anywhere that could be a well-functioning wifi module to read a bin file

i have been try that ，nothing

 

[gaucho]

i have been try that ，nothing

Did u soldered it? Usually there is insulating material on the pcb

 

[2008jiayu]

yes ，i do

 

[gaucho]

yes ，i do

I would try with B_S pin

 

[2008jiayu]

I would try with B_S pin

i also do ，each pin i have been test
