"iPhone 5s - Infinite boot loop (after screen replacement)"に関する回答See if the phone will come up in iTunes with a different screen assembly attached or with none at all. Then you can eliminate that as a possible cause. Look for damage of fuses and components/ ic's around the screws and compare the board with a photo of another board. It's common to let your screwdriver slip and chip a component off the board. Check that the battery is properly seated in the connector and again check for damage Good luck
"Wi-Fi issues, logic board problem?"に関する回答There is a very small metal clip that generally falls off when removing the shield at the top of the board that covers all the connectors. The metal clip makes contact with the long screw at the top and a circle copper pad on the board. If this piece is missing, there will be no wifi. The shield itself serves as the wifi antenna. I tried solving this problem with putting tinfoil on it when I lost the piece, and it didn't work. It seems very picky and will not function without that small metal piece. I never did effectively solve the problem and sold the phone as- is. Good luck Update: Also... Check if the signal is just weak or if there is none at all. Take it close to your router and see if it picks up a signal. If it does, it's very likely a problem with the metal clip and shield I mentioned.
