HTC ONE Android 4.4 KitKat based AOSP ROM: Downloads and Step-by-step Guide

Have a Kit Kat HTC One users!

An AOSP based Android 4.4 ROM has just been released for HTC One by the guys over at rootzwiki. And as it goes for the AOSP ROMs you can download and flash the ROM (+Gapps) on your phone using a custom recovery. However, know that this is the first build of Android 4.4 Kit Kat for the HTC One, so there definitely will be some bugs.

Known Bugs:

• IR Sensor not working

To install Android 4.4 Kit Kat on your HTC One follow the step-by-step given below carefully, and know that this will void the warranty on your phone (if any).

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 HTC ONE M7!

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 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 based Slim Bean ROM on your 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.

GUIDE FOR CLOCKWORKMOD RECOVERY (CWM) USERS

1. Boot into recovery mode. For this:
   • Power off your device and wait 4-5 seconds after lights go off
   • Press and hold Volume Down button then press the Power button to switch on your phone  and release it, but keep holding the Volume Down button. Your phone will boot into Bootloader mode
   • You’ll see a screen with options to boot into fastboot and recovery mode. Here, press Volume down once to navigate to RECOVERY, then press Power button to select it and boot into Recovery mode.
     └ In Bootloader and Recovery mode, use Volume buttons to navigate Up and Down between options and use Power button to select an option.
2. Create a Backup from recovery. It’s optional but very important to do, so that in case something goes wrong you can restore to current state easily.
3. Perform a Factory Reset (This will delete all apps and their settings and game progress). For this:
   • Select Wipe data/Factory reset, then select Yes on the next screen to confirm factory reset (screenshot)
4. Install the First-m7tmo.zip file first. For this:
   • Select Install zip » Choose zip from sdcard (or external sdcard, you know where your files are) » browse to the location where you saved the file and select the First-m7tmo.zip file » select Yes on next screen to confirm installation of the file
     
5. Now similarly flash the gapps-kk-20131031.zip file, as you did in step 4.
   └ Make sure to first flash the ROM file and then the Gapps file.
6. After you are done with flashing of the files, reboot your device. For this, go back to the main menu of recovery and select reboot system now.

That’s all. Your phone will now reboot and it will take some time as it’ll be phone’s first boot after installing Android 4.4, be extremely excited for this!
