HTC designed a monster model which they named as HTC EVO 3D. When I bought my Evo 3D, the very first day I changed my Rom to custom one. Why? Ok let me explain why many users Root their devices & change their Roms to custom one…

Rooting your Android phone enables you to use the superuser, or root, permissions of the Linux-based operating system (OS). This gives you and apps that take advantage of the root permissions more control over the Android operating system and the device & yes you can replace full custom Dev Roms as well after rooting. Actually Roms are designed by developers for achieving max performance along with max & optimized battery timing to your device plus other UI features & tweaks.

Now lets come on the main part, Below is the guide that how to safely root HTC Evo 3D without losing S-ON. (S-ON means your warranty is not void, & S-OFF means you have void your warranty).

Follow carefully & you will get fully functional Root + Rom without losing S-ON

3. Now download these packages ADB Files, HTC Drivers, & Revolutionary CWM recovery .

You can install roms of your choice which you can find at xda forums, but I will recommend LeeDrOiD Rom which is one of the best & stable rom so far which I have personally tested on my device & I am satisfied & still using it.

 How to install Rom:

You have now two choices, either install your Roms or Kernel through Revolutionary recovery method or FlashImageGUI app method. I will prefer FlashGUI method is far more simple & easy to use.

4. Device will take some time after restart at first boot so not to worry about it.
5. You can check Rom’s version by going to Settings > About phone > Software information
6. Now again Open FlashImageGUI & browse Kernel file from sdcard. Select Kernel Image & check both Clear Dalvik & Clear Cache & press Flash Image. Press yes on any confirmation window appear. At the end select Reboot normally
