Thanks Bruce for sharing your method! I went ahead and added it to the guide

Zack is right, this step is just to view and identify the ICs and parts on the motherboard. Do not perform this step if you wish for you phone to remain functional.

Good find on the lens cover! it's only a few dollars so order one and let us all know how it works.

Oops! I replaced the old picture with the correct picture showing the pins on the correct side. Good eye thanks for that!

Great! I will add this into the steps. If you have any pictures of how you did this, please feel free to email them to alcs99@hotmail.com and I will upload them into the guide

Great Video, I posted your youtube link into the guide

The back of the phone does not need to be removed, the picture in step 3 is the "HTC One Rear Housing" that I bought separately on eBay. This piece is sold for $15-30 and you will need to buy this to pull off its intact glass lens and use this to replace the broken one.

Raph, thanks for the heads up that its still difficult to find the htc one lens assembly. When I wrote this I had hoped it would become readily available eventually, but I guess not. I updated the guide to show how to remove the original HTC One lens assembly from the HTC One Rear Housing, which you can buy on eBay, eTrade Supply, or other online sources for about $12-20 USD.

Thats interesting! The coaxial cables connect to the antennas and depending on which network you're on you might have different antennas. This is the Sprint model I believe, what model do you have? A GSM model like an international phone, T-mobile, or ATT? I will make a comment on that in the guide, thanks for the heads up!
