As I could read through the thread, if I just replace the 12 MHz crystal and no other component, I am limited to 13 MHz am I wrong?
Does anyone have a photo of a USB Block Erupter without the 12 MHz crystal soldered on it to see if I can do the work with only a soldering iron and a desoldering pump?
here in my tread you can see (bad) photos of my complete desoldered usb erupters.
