hanging while reading is a bit strange but not impossible.
Please use the newest dev version: git clone https://github.com/flashrom/flashrom.git
And build it at your own (something like: navigate to the resulting flashrom directory, and do: make make install )
After doing so run it again and check if problem still exists.
Btw: Before updating I would always make sure that reading works fine. i.e. run reading cmd twice and compare read results. Only if they do not differ, I´d recommend to write.
