Latest ICS version of Viper 4G have been released for HTC Evo 4G LTE users. But still there is no official news about release of Jellybean 4.1 for HTC Evo 4G LTE. You can still update your phone with custom ROM which will bring ultimate customization for your device.

In this post, we’ll discuss about the features available in this custom ROM and guide on How to Update your HTC Evo 4G LTE with latest ICS  Viper 4G ROM.

Let’s start with features of Viper 4G custom ROM:

·         ROM is purely based on HTC_Sprint_1.22.651.3 RUU

·         Init.d support

·         Pre-installed Busybox

·         RAMdisk tweaks

·         Venom Tweaks

·         SuperSU v0.92 (Chainfire)

·         Deodexed and Zipaligned SDK r20

·         Option to choose between Apex or Nova launcher

 Now it’s time to install Viper 4G custom ROM on your HTC Evo 4G LTE.  But before that, backup all your contacts, messages, notes, call logs, files and other stuff which are important to you. Once you backup all your data, follow the steps given below.

Note: Enable USB debugging on your phone. To do this go to Settings > Applications > Development > USB Debugging. Trick this option and you’re done. Also make sure your battery level is above 50% as low battery can stop the installation process in-between. Only proceed if your device is already rooted.
