It's great. Thank you. Did you also disassemble the dji mini4 or mini4 pro like that?

albert - 回复

Hi. Do you have high resolution on main board? I had my drone played submarine, so I had to clean the board. Few resistors located at the left of LEDs brushed out :(

If I was looking to reset the binding application but I'll be looking at the slc nand 256 flash memory all I need to do is short this chip out to flash it but I'll take out the recent bound

sounds a little over optimistic - 99,9% chance the data is encrypted.
