Switch Out the Covers on the Xperia Arc/Arc S
Replacing hardware can be tricky business. You have to not only be careful of all the small and extremely breakable parts, but you also have to make sure you’re taking it apart correctly and putting it back together just right. For some devices, there are comprehensive video tear downs, but for others it’s pretty much guess work. For the Sony Xperia Arc and Arc S, you now have a guide as well.
The guide focuses on replacing the phone cover. However, since that involves basically disassembling the phone entirely, then it could also be used to replace other pieces of hardware. Written up by XDA Forum Member arcs_austria, the guide comes complete with written instructions as well as a full compliment of pictures to aid in the tear down.
Users are only required to have a few tools. A Torx screwdriver, a Phillips head screwdriver, and something to pry the device apart. You can get a case separator tool, but arcs_austria states that a guitar pick or a sharpened credit card works as well. From there, it’s taking out all the pieces, making the hardware exchange and reversing the process. Of course, there is always a risk that this could permanently damage your phone, so be sure to use the utmost caution when disassembling.
