[One (M7) General] electric123:
I did not put any copper tape on the new module. Since it did not come with it, I assumed its not needed. I simply removed old module and put in the new one.

My phone has a cover case which hides the seam between the screen and the back cover, so you can't see any damage from opening. I did not break anything, but I did make some scuffs below the volume rocker where I pried off the first clip holding the back cover. There was definitely some adhesive as well, making it hard to open first time. It opened much easier the 2nd time. Since I was getting another camera from Etradesupply and paying $18 for shipping, I also picked up a new black back cover to replace my original metallic/white, and a black sim tray. So now my phone is black with metallic speakers grills, giving it a new look. I could have bought matching new back cover, but I wanted a new look for my phone.

There is nothing special to order Omnivision module from Etradesupply, just go to HTC One section and get rear camera. I suggest to get a new back cover just in case you break the old one when opening. Don't forget to peel off the protecting film from inside of new cover over the camera hole, before closing it.

Watch Youtube videos for disassembly/reassembly of HTC One a few times, to either work up the courage, or scare yourself from doing it ;)

Make sure you have proper tools, fine tip screwdrivers, prying tools, etc. People swear by guitar picks, I did not have any, I had a few plastic prying tools, but they could not get inside the seam, so I had to use thin metal prying tool, which scuffs the seam, but gets the job done. Definitely remove the volume rocker and start prying from below the rocker where the first clip is located, once first clip gives in, the rest is easy, but still requires patience and gentle touch.

I have to say, I work with fine tools for a living, repairing PCBs, etc. and even I was a bit apprehensive at first. Even once the case is open, there are very thin ribbons and tiny wires to disconnect/reconnect in order to get to the camera, any wrong move could damage something, so make sure you are up to the task before you go.

Also, in the Youtube video the guys is removing the main board first, then gets to the aux board which is holding cameras, because his goal is full disassembly. Since I only needed to swap the camera I did not remove main board, but I had to lift up its upper edge to slide out the aux board. So you still need to remove all screws at the top of the main board, but not at the bottom, only loosen up those at the bottom. I only disconnected coax cables and ribbons between main and aux board, not the ones at the bottom of main board, since main board was not being removed.

Removing volume buttons strip was a bit scary, its very thin and only held down by glue, requires gentle prying and a little heat to soften the glue.

Once aux board is completely out, turn it over to get access to camera ribbon, lift the socket lock, slide out the camera/ribbon, repeat everything backwards with new camera for reassembly. Keep track of all small screws and their positions, be very careful reconnecting ribbons and coax cables. Don't forget to put back the plastic piece covering part of aux board.
