Actually I was doing this all wrong, inside Flypro there is pinout, so I matched that with pin out of chipmunk but now I'm getting "programmer not detected the voltage of target board" error? Any ideas, I've attached pics of what I'm following, any help would be greatly appreciated.
Thanks

hi dam1inc,you can removed password a1534 2016?

 

[dam1inc]

anybody have luck with BPv4 and this board? i still cannot detect chip ANY help would be greatly appreciated, I can successfully desolder and program this chip using SOFI but thats a huge pain.
thanks

Figured something hope it helps with someone, 820-00244-A comes with either MX25L6435E or W25Q64FV, sooo the W25Q64FV is very easy to read/erase/write but the MX25L6435E is very difficult and so i notice all those that have trouble is because they device have MX25L6435E and all that say easy because they devicce have W25Q64FV...also both chips are soldered to the board differently, see pics.

You choose 25L6473 (instead of 25l6435) is ok, but the 2017 model will be a little harder.
The A1534 model 2015-2016 use 3 types of flash chips.
