The "few cables" made me cut the earphone contactas of the EM-Tech EME1511AFRC part, have to use it with the speaker to hear anything...
Besides the screen is heavily glued onto the front case (not kept in place by the outside "ring" of the phone), since I can't glue it, I gave up with my brand new screen & packed it back. Now, the screen is damaged and the earphone is off.
Too bad I did not see the "teardowns provide a look inside a device and should not be used as disassembly instructions." thing !
