I use to build my Galaxy S3, Note2, S4, and Note3 vith live demo units (LDU). Im always get a LDU of the phone then i get a cheap SMASHED phone then a phone out of the LDU parts.
I got some S5 LDU-s and im just thinking on something: Would be possible to add the required parts (from a chines S5 or something) to the LDU to make it work? One of my friend got a very expensive profession workstation with a good lenses and control unit...
What is actually missing from there?
