How to Unroot the HTC EVO 3D (CDMA)

Most people root their devices to customize the settings, apply tweaks and install custom ROMs. There are hundreds of custom ROMs available for the HTC devices and if you have rooted your device, you must have tried at least one custom ROM on it. Sometimes, when you brick your device doing such things, you need to take your device to the company shop. First you have to unroot your device to reinstate the warranty and only then you can have your device repaired at the shop. Here’s how you can unroot the HTC EVO 3D (CDMA) smartphone.

I. Before You Begin:

    I want to start by sayin’ thx for the easy to follow instructions and links to the files needed, glad you were there, but, if I may? critique a bit…

    n00b jokes aside seein how this article is meant for n00bs,…

    it would be helpful if in your other “How To” on rooting if it was explained 1st that if you have a Evo V 3d Virgin Mobile CDMA to make a backup of EVERYTHING relating to the factory installation BEFORE rooting if one is going to later find out that one will need to S-OFF for many of the mods and because the VM RUU seems to be EXTREMELY rare as compared to the other RUU’s and include the procedure to do so if the possibility even exists without rooting.

    also it would be helpful if the external links to the file actually gave the file instead of registration and a waiting period of 10 posts to even get to see the file, seems a bit much.

    anyway, I’ll wait it out and see if it appears after my 10th post :/

    thx again.

      Agreed about the files…it’s rather ridiculous to publish a “how to” to then keep the files away from those that need them. Not everyone wants to spend every moment of their waking hours doing this stuff!!! In some ways this is becoming works than Corp America and feeding right into the Apple philosophy.

    Open community is going to crap with hiding needed files behind all of the walls. It’s no longer really open.
