I've seen people had success without desoldering. I am sure I ve seen it here. Some 3565 spi flasher but usb only? I cant desolder :frowning:

Unpower disconnecting both ends of power adapter and wait 1h for caps to discharge

Okay but i remember people connecting to some flash pins, while powered off. And it works for them. Not serial. This ch3565 something or so??

This has been discussed a number of times before. The main problem is that you cannot power the flash chip without powering other chips on the board. You must figure out a way to do that safely. Meaning that you

  1. provide enough power,
  2. don't fry any IO pins, and
  3. keep the SoC from running and accessing the flash

I suggest reading what pepe2k says in this thread before connecting anything:
