Install Unofficial CM9 On Infuse 4G And Update To Ice Cream Sandwich 4.0.3 Custom ROM

Samsung Infuse 4G

The Infuse 4G device has been launched by Samsung and, as you might know, it won’t receive the ICS update and numerous AT&T users have complained about it. However if you follow the info in this post you will easily learn how to successfully install an Ice Cream Sandwich custom ROM on your device.

Installing ICS on INFUSE 4G might lower its performances because it packs a 1.2GHz single core Samsung Hummingbird CPU just like the Nexus S and Galaxy S series. But, despite the lower specs packed by Infuse 4G, Entropy512, an XDA community member, managed to create a working CM9-based custom ROM that will allow you to install Ice Cream Sandwich 4.0.3 custom firmware fast and easy. In order to be sure that the new firmware will be successfully installed, you will need to read all the info I’ve listed and, in case you cannot complete any action, then please use the comments field to ask for help.

Calls, GPS, Wifi, Sound, Camera and Video Playback elements, have all been confirmed to be working and you shouldn’t experience any problems while using them.

There are some known issues with the new firmware, but these should be fixed in future releases. There are problems with the ‘Settings> Advanced’ options which are displaying a force close error when you try to open them. Currently, the WIfi tethering, bluetooth and the TV output aren’t working and these should be fixed in the near future. Some elements, such as the camera and car dock audio, are only partially working. Now, if these facts don’t bother you then you should continue reading the rest of this post and learn how to update the firmware of your smartphone.

Before we can move to the installation guide, you need to read the preparation instructions listed below and so you will learn how to properly prepare your Samsung Infuse 4G smartphone to fully support the CM9-based Ice Cream Sandwich Custom ROM. Here’s what you need to take into consideration before applying the actions under the tutorial guide:

  • The tutorial guide will work only with the Samsung Infuse 4G model number I997. Do not attempt to install the unofficial CM9-based firmware on any other device that sports a different model number. You can check your phone’s MN by opening Settings and checking the info under ‘About Phone’ options.
  • Your device should be already rooted and the ClockworkMod recovery should be installed. Make sure to check your app drawer for an icon titled CWM, as that’s clockworkmod.
  • Move or create backups of all your important applications, audio, video, photos etc. on your smartphone’s SDcard. This will prevent your data from being deleted or corrupted, as the SDcard will be the only part left unchanged by the firmware update. Alternatively, you can choose to transfer the data on your compute using the USB cable.
  • If you wish backup the text messages and call logs then you should try to use these Android utilities: Call Logs Backup & Restore / SMS Backup & Restore.
  • Sync your Contacts with your Gmail account and in this way you will be able to restore all your saved contacts on your phone after the installation is complete. Learn how to do it by following the instructions listed in this ‘how-to sync Contacts with Gmail’ post.
  • Make sure that your phone’s battery charge levels are over 75%. This will prevent it from powering down while you’re apply the new ICS firmware files.

That’s it, now you’re ready to move to the tutorial guide and learn how to install unofficial CM9 Android 4.0.3 ICS custom ROM firmware on your Samsung Infuse 4G.

Please note that in case you can’t complete any of the steps below, then you should use the comments field and ask for help. Also, in case your device freezes during the update or it cannot boot the ICS homescreen, then you will be forced to remove its battery and then repeat all the actions from both, preparation and installation, guides.

If you carefully read and apply the instructions step-by-step then you shouldn’t experience any problems while upgrading your phone’s ROM firmware files.

How to update Infuse 4G using unofficial CM9 and install the ICS 4.0.3 custom ROM firmware

  1. Download the latest edition of the CM9-based 4.0.3 ICS custom ROM firmware from here. Click the download link and wait until the zip file has been successfully downloaded on your PC.
  2. Download Google Apps zip pack from here. This will allow you to use Google applications such as Gmail,  Gtalk, Calendar, Play Store etc, as these apps aren’t comprised within the custom ROM’s files.
  3. Both zip files need to be moved on your phone’s internal SDcard.
  4. Power off the device and then boot the clockworkmod recovery.
  5. When in recovery main menu you need to select ‘install zip from sdcard’ and then ‘choose zip from sd card’. Select the custom ROM firmware zip file and confirm that you wish to install it. Wait until this completes and then repeat the same action, only that now you will need to install the ‘gapps’ zip package.
  6. Go back to the recovery main menu and select ‘reboot system now’.
  7. Now, your device appears to stop loading and it will show the Samsung screen, which is why you need to immediately press the ‘Volume UP, Volume Down and Power’ until your device will restart. After the screen goes off you will need to release Power, but keep the Volume UP and Down buttons pressed until it boots into recovery mode.
  8. Now you need to wipe all data and cache. Do it by selecting ‘mounts and storage’ and then select the following options, one after the other: format system, format data and format cache. Confirm their actions and when all have been applied you need to return to the main recovery menu.
  9. Now, you need to repeat the step 5 actions once again. Flash both the custom ROM and the Gapps zips. When these actions are complete you will need to return to the recovery menu and select ‘reboot system now’. This time the boot shouldn’t get stuck again and the Android 4.0.3 ICS home screen should load succesffully.

That does it, now your Samsung Infuse 4G by AT&T or Rogers has been successfully updated to an unofficial CM9 Android 4.0.3 Ice Cream Sandwich custom ROM firmware. In case you have any other questions then please ask away by using the comments sections below.

    Well, I did everything close to these instructions, but instead of downloading the .zip files onto my laptop, I downloaded them directly to my phone and moved them to my external_sd file. I booted my phone in recovery mode, installed the custom ROM and my phone is stuck on the Samsung screen… I tried formatting the system, data and cache from the recovery menu but it didn’t help… -.-

    The only problem I can think of is that I might have installed the wrong ROM (I’ve been trying to figure out how to upgrade to Jelly Bean for the past couple days so there are a few random files on my phone).
