The HTX One X and its variants the One XL, One XT, One XC and One X+ are among the more difficult handsets to repair. While using a rear housing that fits perfectly around the main assembly helps these phones to be visually appealing it also makes disassembly not only challenging but also risky. This repair is not recommended for those without a substantial amount of mechanical experience. You can purchase replacement screens through the links below. You will want to disassemble your One X first to determine whether you have the LCD with a green flex cable or the one that is completely yellow. I have included a link to the lens which is available by itself. However replacing both is recommended as it is difficult to remove the LCD without breaking it.
Update: The green flex LCD appears to be backward compatible so you can order this one for all HTC One X repairs.
In these videos we demonstrate the full disassembly and reassembly required for replacing a broken HTC One X screen. While there may be an option to purchase the touchscreen separately it this is not recommended for several reasons. In most cases the LCD will be damaged during removal due to the strength of the adhesive which holds it in place. Since the LCD is installed on top of the digitizer flex cable you must remove both in order to complete this repair. On the other hand if your LCD is broken you may be able to salvage your original digitizer by removing it without damage.
You replacement screen should have three plastic pieces which are stuck directly underneath where the home, back and settings menu are on the lens. Failure to install these plastic pieces will prevent your buttons from illuminating. Be very careful when peeling back the microphone flex cable at the bottom as it is also very easy to damage.
