I wouldn't read/write anything with that Galletto mate.
It's a chinese clone with bad chips. It may work one, two times... It may not work. Those are bad quality chips and transistors mate.
I have one like yours, it read one EDC16U34 but after I've seen the board closely it ended up in the garbage.
Sometimes it reads, others don't... I've reworked it and after that, worked fine.

Please check the file in attachment. It have the correct information that you need to rework your clone.
