Like a lot of people out there, my digitizer cracked out of nowhere. I tried to search all over the internet for ways to disassemble the phone and replace the cracked glass. The closest thing I could find was from this website:http://www.rapidrepair.com/guides/instinct/instinct.html
It's a guide to taking apart a Samsung Instinct. It matched up pretty close all the way to step 5. I couldn't figure out the rest of the steps to take it apart. But anyways, once at step 5, I was able to see the ribbon from the digitizer and remove it from the board. Taking a very thin screw driver, I carefully removed the digitizer from the front. It is just secured with some adhesive. Once that was taken out, I replaced it with a digitizer I bought from Ebay for $16. Since I could not take the phone fully apart, the hardest part was getting the ribbon connected back onto the board. But eventually I got it in. TWSS.
I am surprised I couldn't find any instructions on taking apart the Eternity. Nonetheless, I just want to say it is possible. I just wish I took pictures while I did it.
This is the old digitizer I took out.
This is what it looks like now:
If any of you have questions, I'll try to answer them. Or if someone can please extend this guide. I just want to make it easier for anyone who has this problem.
