We know you were waiting for it, and now the wait is over. Ice Cream Sandwich Android 4.0 is here for your Motorola Droid 4 in the form of CM9/ICS for Droid 4 ROM, thanks to XDA developer Hashcode who has ported over CM9 to the Droid 4. It is a kang which basically means that the developer has taken the code from CM9 and made it compatible with the Droid 4, so it’s not an official Cyanogenmod release.

The ROM is a beta and a work in progress, so bugs and issues are to be expected, along with features and functions that may not work properly. So proceed with caution while trying out the ROM and make sure you know what you are doing.

Read on to find out how you can get Ice Cream Sandwich on your Droid 4.

Compatibility

This ROM and the guide below is compatible only and only with the Motorola Droid 4, model number XT894. It’s not compatible with any other device and may render an incompatible device unusable. Check your device model in Settings » About phone.

Warning!

The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know exactly what you are doing. If any damage occurs to you or your device, including a bricked, non-functional device, we won’t be held liable. You have been forewarned!

Known Issues:

  • Some people are having issues with Wi-Fi.
  • The CM9 built-in WiFi Tether won’t work. You need to use the “WiFi Tether” app that’s bundled into the ROM. Once you open it, hit [menu] and “Settings”. Select “Change Device-Profile” to “Motorola Droid RAZR (CDMA/LTE)”.
  • You can safely ignore the error about “sd-ext” when wiping Dalvik Cache in Safestrap.
  • Known issue w/ Bluetooth while it’s on but NOT connected to any devices, audio routing to the entire phone gets wacked and you won’t get any sound at all. Fix by turning off Bluetooth.

What’s Not Working:

  • Camera needs to be fixed. It should be working, but it errors out.
  • HW Video Codecs (in progress)
  • Bluetooth on but not connected = loss of all audio (in progress)

Pre-Installation Requirements

  1. Important!! A Droid 4 with Safestrap recovery installed. Get Safestrap recovery from this guide → here.
  2. 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.
  3. Sufficiently charged battery, at least 50% is recommended.

How to Install CM9/ICS for Droid 4

  1. Download the latest version of the ROM from the official development page.
  2. Download the Google Apps package (this is required since the ROM itself doesn’t contain Google apps like Market, Talk, etc).
    Download Link  |  Filename: gapps-ics-20120304-signed.zip
  3. Transfer the two files downloaded in step 1 and 2 to the root of your external sdcard on the phone.
  4. Turn off phone and boot into recovery. To do this, turn on phone, then press the Menu button on the splash screen that shows up to enter recovery. In recovery, use Volume keys to scroll up and down and power key to select an option.
  5. [Optional] Perform a Nandroid Backup of your existing ROM, so that you can always restore it from recovery if something does not work out with this ROM. To perform a backup, select Backup and Restore » On the next screen, select Backup again.
  6. Once in recovery, perform a wipe:
    1. Select “wipe data/factory reset”, then select “Yes” on next screen to confirm. Wait a while till the data wipe is complete.
    2. Select “wipe cache then select “Yes” on next screen to confirm.
    3. Go back to the main menu, select “advanced”, and then Wipe Dalvik Cache » Yes – Wipe Dalvik. Then go back to the main recovery menu.
  7. Now select “install zip from sdcard”, then select “choose zip from sdcard”. Scroll to the ROM file on the sdcard and select it.
  8. Confirm installation by selecting “Yes — Install *your_rom_name*.zip” on the next screen. The ROM will now start installing.
  9. After the ROM finishes installing, select “go back” to go back to the main recovery menu.
  10. Now repeat step 7, but this time select the Google apps package file gapps-ics-20120304-signed.zip to install the Google apps package.
  11. After the installation is complete, select “go back” then select “reboot system now” to reboot the phone.
  12. IMPORTANT! If you are coming from a Gingerbread based ROM, after you set up your Google account, make sure you DO NOT let it restore your apps and settings. Uncheck the Restore option when you are asked whether you want Google to restore your apps and settings.

Special Note about 4G/3G Data

The data on this ROM is a bit finicky. When you reboot, you will probably need to go to: Settings -> Wireless & networks -> More .. -> Mobile networks. Click on “Network Mode” and goto GSM-only, wait for 5 seconds, and then back to LTE/CDMA. This should help data come up.

Your Droid 4 is now running Ice Cream Sandwich Android 4.0.3 with CM9/ICS for Droid 4. Visit the original development page for more info and to get the latest updates on the ROM. Share your thoughts on the ROM in the comments.
