This manual doesn't mention to take out volume and Power Buttons and removing the lower PCB with the USB port and LED!

I would edit but unfortunately I didnt take any pics

As Robin says, this misses out a few bits that are needed if you are trying to replace the screen and digitiser - two buttons, lower usb assembly and also a very small, mysterious, soft rubber insert that goes at the top and no doubt does something vital. Sorry also no pictures but none of these are exceptionally tricky - though the usb assembly needs gentle handling and patience. It took me a lot longer than the guide suggested but thanks to those clear instructions it all got done … and now my faithful old phone works again! Thanks a million!
