I bought a kit lcd + touch + frame to replace because I broke my.

But they lack the two connecting cables of motherboards, those of the step 13 and 14. How can I remove them from the broken frame and insert them into the new one?

Hello, I have replaced the display of a Find 7 (not 7a) and now have a phenomenon. The smartphone does not charge the battery. The software shows, the battery is being charged. Also, the charging LED works. I can transfer data via the USB port. So everything works fine - only the battery didn't charged. Of course, I have already tested various charging cables and batteries. Likewise, I changed the USB board. Unfortunately again and again the same problem. The smartphone does not charge the battery.

Greetings and sorry for my bad English
