I found this guide excellent and it is very easy to do. I didnt have the plastic opening tool but I do have a long thumbnail. It worked very well.
Too bad the replacement board I got has a defective soft button connector. I had to disassemble the phone 3 times. I thought I did It wrong the 1st time. Opened the phone a 2nd time to check.... closed the phone... nada.... USB changer works but no soft keys... put my old board back in to check the soft buttons and they work. Sent an email to the company that I bought the board from... still no answer after 24hrs. If I still have no answer by the end of the week I will post which company sold me the defect board so no one else gets burned from them. I will then try to unsolder the USB from the new board to replace the USB on my old one.
