Remove Sim Tray before opening the case, chance to broke the case with sim tray inserted.

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.

Definitely need patience for this. Unfortunately, I broke one end of the plastic opening where the SIM card tray goes. Quite fragile right there, especially as you wrestle with the corner. I think it broke as one of the corners popped off.

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.

what do i do if the screw is stripped?

Amulya, · Reply

How did you strip the screw? Torx screws are pretty hard to strip

Ethan Chow,

Why is it important to remove the battery because I cannot see it causing any hindrance in removing the black panel that houses the camera and other circuitry

Rajat Singh, · Reply

Rajat, for any repair the battery should be removed first. Its easy to accidentally short out the battery when using screwdrivers to loosen screws.

Don Barthel,

I successfully replaced my speaker without removing the battery. Better save users some time by deleting steps 4 and 5 from this tutorial. Thanks a lot by the way :)

Indeed you can probably technically remove the speaker without removing the battery however removing the battery as soon as possible once you get inside, or before getting inside a device when possible, is not worth! First it prevent from any short circuit that can destroy the device and it is also a way to ensure the device is totally disabled before starting fixing it. Those devices today are always powered even if turned off. So to conclude: Always remove the battery before you make any job inside a device. Do this step in priority as soon as the battery can be removed.


I didn't remove the battery, and I was able to complete the install of the headphone jack just fine. I did disconnect the battery, however, since I didn't want to take any chances (some people saying that the phone never really powers off completely made me cautious).

The battery removal step is unnecessary and difficult. You should disconnect the battery, but there is no need to rip it out of its glued in position.

Malcolm Smith, · Reply

The Battery removal is NOT NOT NOT NOT NOT something you should skip.

You do not need to fully remove the battery but make sure it is disconnected!

You can complete without any apparent damage but could potentially cause ESD that will manifist itself down the road.

It's a safety precaution to prevent static damage to your components.

Cut or remove the tape from the antenna & battery before proceeding to try to remove the battery. They are taped together and you can easily damage the antenna if you are not careful. Even after the tape is removed, be careful of the antenna wire while removing the battery.

Wish I had seen your comment before gently prying up the battery and pulling the white antenna cable straight out of its tiny gold connector. Down to wifi-only as I await the replacement cable from eBay.


I found the #00 screwdriver too big to remove the screws in my N4. Sadly, I don't have a #000

laidig, · Reply

I also had trouble with the screw: The (supposed) PH00 from a cheap kit didn’t fit; I also didn’t have a PH000. – But I managed to (carefully and very slowly) remove them with a PH0 (yes, a larger one!), which just barely got a grip on them.

Well that sucked. Really wish you had mentioned the antenna cord being taped to the side of the original battery. I yanked it out when prying off the glued down battery and ended up with a wifi-only device. The Nexus 4 battery replacement guide could really use an update.

Also confirming that the battery removal step is unnecessary (wish I had read the other comments before proceeding with it)

Isn't the antenna cable attached to the battery through the blue tape in the picture? In my first attempt replacing a broken screen I broke the antenna cable while removing the battery, so I had to buy a new cable to replace the old one.

jcollado, · Reply

I just did the same thing. Wish I had seen your comment earlier!


The battery was tightly gluid. To be able to put some more force than with the plastic opening tool I was using, I used a children plastic eating spoon. Worked like a charm!

Kurt, · Reply

I have a suggestion for all those who need to get the battery out. If you start from the top of the battery where the contacts are, you will notice that you can bend the top of the battery to some extent by lifting it with the plastic tool. This allows you to slip in the blade of a slim spattle (even if the blade is an inch wide). Since the cage of the battery is made of metal as well there is no danger for the chips and circuits. If you rock the blade to the left and to the right and apply a littel downward pressure you literally cut through the glue underneath the battery and will get it out in no time. Plus, there is no danger of cutting the antenna ;)

I hope it works for you guys.

I am trying to replace the battery. Since the battery originally glued on, if I replaced a new one, do I need to glue it back on as well or the connector should be able to hold it? If I need to glue it back on, what glue should I use to be safe on the phone??? Thanks a lot!
