Build 40 of AOKP for AT&T One X [Guide]

Advertisement

Build 40 of AOKP ROM has been released for the AT&T One X, by XDA Senior Member rohan32. AOKP is an Ice Cream Sandwich Android 4.0 based custom ROM that features a stock Android interface without any bloatware or unnecessary apps, with advanced customization options that let you customize almost every aspect of the interface, along with fast and smooth performance.

However, the ROM isn’t completely stable at this point and might have a few bugs and issues, and a few things do not work. Here are the things that do not currently work on the ROM:

  • NFC
  • Video Recording is broken
  • Panorama mode in Camera app
  • 2G/3G switch

As you can see, the list of things that do not work is not too big and most of the major stuff works. So if the things listed above are something you can live without, you should certainly try out the ROM.

Read on to find out how you can install AOKP Build 40 on your AT&T One X.

Compatibility

This guide is applicable only for AT&T One X. DO NOT try this on the Rogers One X or any other device.

The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.

How to Install AOKP Build 40 on AT&T One X

  1. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    Important! Don’t forget to at least make a backup of your APN settings, which you can restore later if your data connection does not work after installing the ROM. Use the backup guide to find out how.
  2. Unlock the bootloader on your AT&T One X by following the guide → here. Unlocking the bootloader will wipe everything from your phone, including the data on your SD card, so backup everything before unlocking bootloader. This will also void your warranty.
  3. Install TWRP recovery on your device by following the guide → here.
  4. Download the latest version of the ROM from the official development page.
  5. Download the Google Apps package. This will install apps like Market, Gmail, etc. which are not present in the ROM by default.
    Download Link  |  Filename: gapps-ics-20120429-signed.zip
  6. Copy the 2 .zip files downloaded in steps 4 and 5 to the internal SD card on the phone (do not extract them).
  7. Switch off the phone. Boot into the bootloader mode first by holding the Volume Down button while powering on the phone. Then, using the volume buttons, highlight RECOVERY then select it using the power button to boot into TWRP recovery.
  8. Tap Wipe, then tap Factory Reset, then slide the blue circle at the bottom to the right to confirm data wipe. After data wipe is complete, tap on the home icon at the bottom left of the screen to go back to the main recovery menu.
  9. Select Install, then scroll to the ROM’s file on the SD card and select it. Confirm installation by sliding the blue circle.
  10. After installation of the ROM is complete, go back to the main recovery menu. Then, select Wipe, then select Cache/Dalvik, followed by sliding the blue circle to confirm cache wipe. Then, go back to the main recovery menu.
  11. Then, again tap Install, then select the gapps-ics-20120429-signed.zip file to install the Google Apps package.
  12. After installation is complete, select Reboot system option to reboot the phone and boot up into AOKP. The first boot will take up to 5 minutes.

Important! Enabling LTE data connection if it does not work:

The first version of the ROM does not contain the APN settings for the LTE data connection. So, in order to make the LTE data connection work, do the following:

  1. Goto Settings > More > Mobile Networks > Access Point Names, click menu, then click New APN.
  2. Then, enter the following settings and save the new APN:
    • Name: ATT PTA
    • APN: pta
    • MMSC: http://mmsc.mobile.att.net
    • MMS Proxy: proxy.mobile.att.net
    • MMS port: 80
    • MCC: 310
    • MNC: 410
    • Auth: none
    • APN type: default,mms,supl,hipri
