tmsulica: I found the M470L6524BT0-CB3 module on ebay recently.
I used a hot air gun to desolder the chips (wl700ge).
The pbfree solder needs quite a lot more heat/time to melt.
I Soldered one chip into U3, but could not get the power led to come on.
Rechecked the solder a couple of times.
Finally pulled the chip back off and resoldered the original which works fine again - happy and sad about that.
I will try once more tomorrow with a fresh chip.
