[One (M7) General] UltraNoob:
Another Success story over here. I was getting quite tired of having a silver/white phone (especially in canada since we didnt get the black version for a very long time) so against all odds i decided to do a housing swap.

The back housing was an easy part to find but i had a few options from the front.

1. I could either buy a whole front housing including display

This wasn't a very good idea for me as my display was pretty much perfect and a waste of money $~80 USD

2. Buy Speaker grills separately

Could buy from etrade supply, but price + shipping kills the deal ~$20 USD

3. Buy the front housing without display and try to remove the grills to put on my phone

Ended up going with this option since it was the cheapest ~$7 USD.

Hardest part of this entire process was probably removing the back housing. Now that I've done it you should definitely start by the volume rocker. Get one of those guitar picks and try to force it into the bottom portion of the volume rocker. Once a little gap is created start directing the pick toward the bottom of the phone.

Once at the bottom enough clips should be released so that the back can easily be removed. Once the back is removed you will notice a screw in the top right corner of the back of the phone (beside light and proximity sensors). You will need to remove this screw to take off the top speaker grill. There is a gold piece under the screw that will fall off when you remove this screw. Just make sure to save this for reattachment later.

You should now take a plastic pry tool and try to remove the top speaker grill. It is now only held on by adhesives so you can either heat up the phone with a heat gun and remove it or like me just pry slowly until the grill gives. The bottom speaker grill can be removed in a similar manner (except no screw). I had to do the same thing with the replacement front housing i received to transplant the grills.

At this point i could have taken a different approach. I could have completely disassembled my phone and heated up the old front housing to dislodge the display and transplant the display onto the new housing. I did not want to tear down my phone or chance wrecking my display so i decided with just the speaker grills.

Now the tricky part. You will now need to remove excess glue from the grills and around the speakers and reattach the grills to the housing. I tried two different methods of reattaching the grills. Not wanting to glue the grills i tried double sided tape. Needless to say the tape failed miserably leaving massive gaps around the phone. The second option was super glue. You have to be real careful where you decide to use the glue as it can get on the senors/front camera and can cause issues. I only glued on the side of the camera since the other side had a screw to hold it down. I then repeated the same process for the bottom grill. Now my front looked perfect except for a minor detail. Some of the glue had seeped through the holes in the grills and made some marks on my otherwise perfect assembly. Luckily some nail polish remover got rid of most of the excess glue. All that is left now is to put the screw back in and attach the new back housing.

After reattaching the back housing phone is now exactly how i wanted it in the first place All black everything :)
