i = self.firmware[self.offset:].find(magic_str)
TypeError: argument should be integer or bytes-like object, not 'str'

This occurs unexpectedly and I didn't change anything from the original code, anybody could help?

Steps to reproduce? Which python is being used on your system?

I configured python2.7/3.5/3.6 to build the code but still I met the same error. When I use python3.7 to build, another error as described in issue #10333

@DaHaiHuha Thanks for the report. Should be fixed in the master branch now.
