once the screen bezel is removed from the slider case, the flex cable is connected in two places

the main LCD flex cable is connected in the center. remove the tape with tweezers and flip up the black lock on the connector. the flex cable will slide out

the secondary flex cable is connected to the controls board. remove the tape with tweezers and flip up the brown lock on the connector and the flex cable will slide out

in red are the connections for the ear piece and light sensors. they are connected via flex cable to the main LCD. flip up the brown lock and slide out the flex cable

gently pry the rubber noise cancelation mic out of its hole. the sensors and ear piece can be pried up with the case opening tool

the main LCD can be removed with the case opening tool

in blue is the track pad connector. flip up brown lock. it can be slid out of its connector.

in magenta is the main flex cable connector for the digitizer. flip up the black lock. slide it out and be extremely careful as this flex cable is much thinner than the LCD flex cable.

in green is the main chip for the digitizer. it is attached to a flex board and glued to the main controls board. to replace the digitizer this must be pried up to remove the main controls board

the main controls board in orange maybe be removed when the digitizer connections are removed. you can pry it up with the case opening tool

you must remove the track pad to replace the digitizer and glass

the digitizer and glass are glued to the screen bezel. the glass can be removed by heating it with a heat gun until the glue is soft enough to pry up. THIS WILL MOST LIKELY BREAK THE GLASS

the digitizer can be replaced by first sliding the chip and flex cable through the trackpad hole and sliding it into the opening provided

when you're ready, remove the strip to uncover the adhesive for the glass and carefully place it on the screen bezel. Place it properly the first time as once it's in place it cannot be moved
