error: control reaches end of non-void function [-Werror=return-type]

Got the subject error message compiling in platformio IDE...

Compile error is fixed by adding
return false;
to the end of the soUpgrade() function. I'm assuming that false is the right default return value... I have not got as far as testing the code.
