(1) Removing the back panel will destroy it. All intending any repairs should have a replacement panel available before beginning.
(2) Replacing battery is as described.
(3) Author does not identify the wifi antenna correctly, nor supply advice on replacing it. Actually the wifi antenna is located at the lower right corner of the Xperia Z2 not upper left as shown. A connector wire runs along the edge in a groove and leads up to a connection on the motherboard. To replace wifi antenna unclip the connector, unscrew the mini circuit board, then reverse the steps with new board/connector.
