    • Power down your device.

    • Use your plastic opening tool to wedge between the seams around the sides of the device. Pry open each side, one at a time. For some a finger nail may be best. The case comes up quite high to the glass.

    • Do not pry near the USB port at the base of the device as you may crack the rear panel.

    • Using the flat end of a spudger or your fingernail, flip up the thin portion of the connector (opposite of the side where the cable inserts) to release the cable from its socket.

    • DO NOT PRY the socket on the side where the cable inserts, or you may break the entire socket off the motherboard.

    • Slide the cable out of the ZIF socket.

    • Remove the gray seal covering the top center screw on the daughterboard.

    • Be aware that this action will void your warranty.

    • Be sure to store the seal in a place where it will not get dirty and can retain its stickiness.

    • Use the flat end of a spudger or your fingernail to carefully flip up both retaining flaps one each of the ZIF sockets.

    • When disconnecting the ZIF sockets flip them outwards to the edge of the board/towards the cables respectively.

    • Be careful not to damage the pin connector. Pull parallel to the device, not up.

    • For more info on how to disconnect ZIF connectors, check out the Recognizing & Disconnecting Cable Connectors guide.

    • The daughterboard will now lift easily up and out of the device.

    • Use care during reassembly. This daughter board is a very sensitive part. It is easy to fry the digitizer part of this board if connections are made in the wrong order. Complete all other cable connections before connecting battery power.

According to these repair stories, it worked fine without any mentions of a need to calibrate: Nexus 7 (2nd Gen Wi-Fi) LCD Board

Great guide, easy to follow, the only input I would add is that stating which direction the zif connectors open would be helpful for newbies like me :)

My nexus 7 2013 wifi is charging fine with the existing board, but when I connect it to PC, it doesn't open the USB connection. Now, do I get the replacement or is this is a software bug?
