    Carbon Fiber Back Mod - Install & Tutorial

    Hi all,

    mikevember started a thread, http://androidforums.com/htc-evo-4g/78740-carbon-fiber-4g-back.html, a while back which inspired myself and a number of others to look further into it and try it out. Since I wound up purchasing a Google IO Evo, I'm the first to go.

    So I documented everything here for you all.


    First, you'll see that I ordered two sheets, one light and one dark carbon fiber.

    I wasn't sure which one I'd want, so I said the hell with it and got one of each. And worse case scenario, if I screwed the first install, I could rip it off then use the other sheet to try again.


    - Hair Dryer
    - Utility Knife
    - Cardboard to cut on
    - Sewing Needle
    - Scissors


    First you'll see I cut a chunk of the decal away, since I wouldn't need it. I figured I'd practice first, so took the cap to a spray can that was curvy, and worked with that. Here's a few samples.


    I was able to pull the decal on and off, stretch and restretch it, as I kept heating it. I played around for several minutes and this material is very forgiving. It won't "permanently" shrink like say, saran wrap, which helps a lot. But at the same time, that means the material won't wrap around tighter curves as well, but that's okay.



    Okay, onto the Evo.


    Here I am now applying the decal.


    Once I did this, I started to cut away the excess using scissors then used the utility knife for closer trimming. After this, I heated the hell out of it for several minutes, pressing up the sides to encourage adhesion shrinking.


    Then I cut out the hole for the camera lens and kickstand.



    Then I went back and trimmed up the edges as best I could. I noticed that nail clippers, curved and straight, helped tremendously in cleaning things up. Normal curved nail clippers worked really well for trimming the rounded corners.


    Next, I used a needle to pop out the holes for the speaker. I first poked from the inside of the back, then pushed the needle back through the outside of the back.

    Finally, I cut the holes for the flash. That was the biggest pain in the ass for two reasons. First, I used the "cut a +" technique that I posted from a tutorial video in the original thread. Don't do that... cut a circle out instead. Eventually I was able to trim away as much of the excess as possible but it was a royal bitch, because the holes are so small.

    And here's the final result!

    So here's a slew of random thoughts.

    The decal material feels really good. It's not super slippery and textured nicely.

    There's still teeny tiny jagged edges in my cuts. Not the cleanest job, but its good enough for me.

    When you make your cuts, make them all from the inside of the back, adhesive side UP.

    Uhm, that's all I can think of. Any questions?

    One suggestion would be to use an X-acto knife or similar small blade hobby knife. They would be more manageable for the small detail cuts.

    Question... Once it cools off and is formed to the cover, is it rigid enough you could use a nail file or some fine sandpaper to smooth up the edges? Or is it more of a softer playable material?

    It's a decal/sticker, so you might be able to do that. But it could tear the material too? Might be worth trying with a piece of scrap.

    I'm only using a cheap hair dryer, so it's not like you're heating this material to where you cannot even touch it.

    thanks for the tutorial. how much pulling/stretching did you have to do for the corners to get the film to conform? or did you just heat and pressed them on? if so, wouldn't there be creases from the excess material, kind of like the spray paint cap but to a lesser degree?

    also, did you use the sample-size sheets?

    I only had to heat and press. Never had to stretch.

    The curves on the Evo back are nowhere near as extreme as that of the spray can cap, so it wasn't an issue.

    I ordered my sample from 3M Di-NOC Carbon Fiber Vinyl : Carbon Fiber Gear

    By any chance, is that where you ordered yours? I am big into cars, used to be huge into tuners (Now Muscle cars though) so this will fit my hobby well. (Previous car was about 25% real carbon fiber on the exterior)

    GP - yes, that's where I ordered from as well.

    Pretty cool. I ordered two myself - the dark and the silver. I'm wondering if it would be better to cut it larger than the back and the use a longer blade (like a filet knife) to cut the long final cuts evenly...might cut down on frayed ends.

    I'll probably try it but I ordered this as well (in Evo form, not HD2):

    If I was you, I would've cut out the HTC logo.

    Personal preference - I could care less about showing the logo. To me, that breaks up the feel of the back, but to each their own.

    Bek- Yeah I know. Just sayin' though. Still looks good.

    Yeah that would come out pretty nice too, or maybe putting some diamonds in there lol.

    Good writeup. Wish the pics were a little clearer though. Mine showed up today :) No phone to stick it on yet though...

    congrats on the great job. It looks just as great as I imagined. I will have to wait until friday to do mine but I am glad it turned out awesome for you. A little more heat on the edges should shrink up the frayed parts. I am not 100% sure on that but you may wanna check the original precentral forum to check on cleaning up the edges. Again, congrats and I am so stoked to do this myself.

    Nice job, looks great. Do you think it would be possible to use a dremel sand and smooth any rough edges left over from the knive?

    Is it possible to remove it after a week? I wish someone would make a brushed aluminium back door, like the one on my zune hd (its a really small solid mp3 player). Zune on adroid would rock too

    DI-NOC comes in all kinds of patterns.

    You should be able to request a sample from this site...

    I also am curious as to how well the DI-NOC can be removed. After removal does the cover look like new?
