Introduction
This guide shows how to remove the back case from the Nexus 4, giving access to the internal features of the phone. This will take a couple of minutes.

T5? Mine needs a T6
Mine used the T3, T 4 and 5 were way to big?

Gently open the back case by prying along the edge of the cover, starting at a corner of the phone and circling around the phone using a plastic opening tool.
Tried using the smaller opening tool first, but the tip broke off quite violently. Switched over to the bigger one and that worked a bit better.
Just be very patient especially around the corners.
Seriously, you can use your nails to get a better grip and feel the snap before you break anything. My plastic opening tool didn't work as expected and left pieces of plastic inside the case.
Sorry for my poor english, i'm french ;-). I change my N4 backdoor. I agree with the fact that you must be patient to remove the whole backdoor. At the beginning, it's easy to open a breach, but to remove the entire backdoor, i take less than 10 minutes. I break an opening tool, i use my nails, and with my last plastic opening tool, i turn around the phone and i finally full open it. So be patient and do not force. Thx I fix it !
So great to have these instructions. I ended up using a credit card and slid it in between the case and cover. I started on the bottom side where it was loose, forced it to the corner. when it popped up I kept sliding it around. I did that all the way around and then used the tools to lift if up.
I found out that the bottom right corner (looking at the screen) is easiest to start from. Be very careful near the buttons and the sim tray, the plastic gets easiely deformed there. Took me quite a long time and lots of patience to not break anything.
Just in case you've never opened such a compact, tightly snapped device before (such as me): Just attempt to insert and _slide_ prying tools and an old plastic card around the case for a few times, it appears the case will eventually separate more or less "on it's own" if you keep doing this. Attempting to visibly PULL the case off edge by edge does NOT help (I just spent almost an hour to figure out that attempting to use the tools like a crow bar does not yield any viable result despite looking good at start). Apart from unnecessarily warping the case, attempting to pull the case off may also result in the case getting stuck on the power button - you want to avoid that...
Also check that all button "pins" are still there when the case separates; for me the power button "pin" (the external plastic springy bar) came loose and needed to be reattached.

I have made some rearrangement at this guide:
It more logic to remove the tray before removing the screws.
I have used some pictures from the teardown to clarify, particularly for showing the inside of the Nexus 4 showing the battery installed. The original picture did not show the battery. I have also made better reference to the tools.
I ordered the back case using the provided link at etradesupply.com, and noticed it is not an original part: the wireless charging does not work at all (the coil has a much higher resistance than the original one). After insisting, they sent me another one, which gave the same result. Better avoid buying there if you expect original working products...
What about the buttons and the NFC? I can buy a back cover with NFC included, but most seem to not have the buttons. Is it easy to remove the ones from the old cover and install them in the new cover?
