I started by removing the volume button and started using those "guitar picks" around going down. Added some heat to unset the glue and moving slowly I started prying open the right side (when you are looking at the lcd). Than continued moving down until the left side was stuck. After that I went high on the volume button to set the whole right side open.
Now I'm using the other tool (the one that looks like a lever?) I started opening the left side. This side was a lot harder so I applied heat again. After that the glue wasn't an issue and it started to open nicely. Now I have the phone open and I'll see if I can get it working again.
Sorry for the English. I'm too excited to correct the mistakes and I'm not from an English speaking country.
Edit: added tools pictures.
The guitar picks were used to start opening the phone. The green and blue tool were used to open the left/top/bottom sides. The light blue tool was used mostly as a lever on the right side that was already open.

Overall experience while opening the HTC One (compared to the iPad 2/iPhone 3G/S/4S/iPod touch 5th/Motorola Atrix/Transformer Prime) I would give it a 4. The iPad being a 2 (almost impossible to open without a heat source and nearly impossible to mount a new glass without issues).
