Note: This is a very non professional way but easier and much more simple so don't start ranting about it. Do this at your OWN risk as it may lead to damaging the device. Yes it is possible but there is a easier way to do it except it may be pricey depending on your device. What i would do is i would buy the whole assembly to be sure there aren't any artifacts left on the display from high pressure. I have repaired an iPhone 4S and it was very easy. Without an LCD separation machine it might be slightly difficult. And one more thing. If the display is jutting out DONT push it back in as it will make the repair much easier if you leave it alone. Why i say this is because you wont need a hair dryer or a heatgun just simply take your spudger tool and go along the edges of the display and pop the clips and bam your in! Then once your in disconnect the display assembly cable and take off the old display and put the new one in and plug the display back into the same place it was in. Then once its in re-clip it...
good job for making this as least complicated as possible i completed the guide
