Good day!Allocation scheme on the Internet - wrong . When checking the checkpoints appeared that pinout is shifted by one digit. Scheme pin 2 actually corresponds to the real one .
10 pin on the scheme in reality 9. 9 pin - NC, put a new chip WI-FI and everything worked properly

When pads are missing, you can most of the time dig down and find the second layer where the pad was connected to.
Just fill up the hole with soldering paste and reheat. Now you have a mini ball island.
