[How to] Sprint HTC One Android 4.4 KitKat based CyanogenMod 11 (CM11) AOSP ROM

CyanogenMod 11 builds have started popping up for various devices now, and the Sprint HTC One is the latest to get the CM love.

This isn’t an official CM 11 release, but has been built from the open source CyanogenMod code. It includes all of the features that you’d typically find in an official CM release though.

To install Android 4.4 based CM11 on your Sprint HTC One, you’ll need a custom recovery installed on your phone. And make sure that your recovery is updated to the latest version available, since both TWRP and CWM users have been reporting that Android 4.4 Kit Kat is not compatible with older versions of both these recoveries.

WARNING!

Warranty may be void of your device if you follow the procedures given on this page.

You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.

CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be 801c!

Do not use the procedures discussed here on any other device. You have been warned!

BEFORE YOU BEGIN..

You must do this pre-installation stuff before attempting to install the ROM on your Sprint HTC One in order to avoid any complications later, and have a smooth and successful process.

BACK UP YOUR DEVICE

Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.

For help on Backup and Restore, check out our exclusive page on that linked right below.

CHARGE YOUR DEVICE

If your android device powers off due to lack of battery while the process is underway, it could damage the device.

So, make sure your device is adequately charged — at least 50% battery of the device.

EXAMPLE VIDEO

If you haven’t used a custom recovery, either CWM or TWRP, before, to install a .zip file of a ROM on anything else, then we suggest you first watch a video of that, given right below, to get familiar with the process.

Just fyi, the video below shows installing a .zip file (of recovery) on Galaxy S3, but it doesn’t matter as the process remains exactly same. So, once you are finished with video, jump to downloads and step-by-step guide below.

You’ll need either CWM or TWRP recovery for installing the AOSP Android 4.4 KitKat ROM on your Sprint HTC ONE. And since CWM and TWRP recoveries function differently we’ve put together separate guides for both of them. So if you’re a CWM user, follow the CWM users guide and if you’re a TWRP user follow the guide for TWRP users.

NOTE: Android 4.4 requires latest version of CWM and TWRP recoveries, otherwise the Android 4.4 ROM won’t install fine.
