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!

My Nexus 4 Battery socket on the Motherboard has blown off.

How do i retrieve the Data from my phone. Please help me !!!

If you want to exchange just the MB there are some steps you can skip, i.e. step5 (removal of the battery), steps 7 & 8 (removal speaker), steps 10 & 11 (removal of the audio port, unplugging is sufficient) and step 15 (just unplug the antenna cable from the MB)
