Update HTC Evo 4G With CyanogenMod 10 Jelly Bean Firmware

Yes, there are a lot of devices getting Android 4.1 Jelly Bean update via custom ROMs but there hasn’t been any yet for the HTC Evo 4G. This was true until now as XDA Senior Member jmztaylor has worked hard to make CyanogenMod 10 work on HTC Evo 4G. This ROM will run on Google’s latest version of Android 4.1 Jelly Bean. This post is a tutorial to help you install CyanogenMod 10 on HTC Evo 4G. Make sure you backup all data and install this custom ROM as this requires a full wipe to prevent force close issues.

Jelly Bean on HTC Evo 4GBefore you proceed with the steps to install Jelly Bean on HTC Evo 4G, make sure you have unlocked the bootloader of your phone via HTCDev.com, rooted your phone and installed ClockworkMod Recovery on it. Luckily you don’t need Android SDK installed as in HTC One X to flash the boot.img and this ROM can be installed via the recovery mode.

This ROM is currently in the development stage and there are a few things that do not work in this ROM. To check out what is working and what is not working, you can head over to the original thread and also download the ROM zip file and Gapps zip file from the same thread.

Prerequisites

Since this ROM requires a data wipe in recovery mode, we suggest you to backup data on your phone.

  • Back up all apps using ASTRO File Manager. You can get the APK files using ASTRO and later restore it. Rooted users can use Titanium Backup which also backs up data along with the apps.
  • Back up all contacts to SD card.
  • Backup SMS on Android.
  • Backup call log on Android.
  • Have minimum 60% charge on your phone else you might get stuck while the update process is running on your device.
  • Remove any security or Anti-virus app if you have them installed.
  • Enable USB Debugging. This can be don by Settings>Applications>Development and making sure that USB Debugging is checked.
  • While in recovery mode, do not forget to make a nandroid backup.
