Unofficial Cyanogenmod 9 (CM9) for Infuse 4G. Update to Ice Cream Sandwich via a Custom ROM!


The Infuse 4G seems to have no hopes of getting the official Ice Cream Sandwich, thanks to Samsung only deeming their dual-core phones to be worthy of Android 4.0. However, the custom development community is always there to help. Elite Recognized XDA developer Entropy512 has started building CM9 ROMs for the Infuse (after the previous developer left XDA), which bring you Ice Cream Sandwich Android 4.0.3 in custom ROM form.

The ROM is not fully complete yet and is in the beta stage, so there are a number of things that don’t work, either properly or at all. So be sure you take a look at the list of issues below before trying out the ROM.


This ROM and the guide below are compatible only and only with the Samsung Infuse 4G, model number I997. It’s not compatible with any other device. Check your device model in Settings » About phone.


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.

ROM Info


Developer → Faryaab

Partially Working:

  • Camera (front camera is zoomed in excessively)
  • Car dock audio (possibly desk dock too, untested) – Some issues with ringtone playback when docked – This is native dock audio, not using the Car Dock Redirector app workaround.
Not Working:
  • Wifi tethering – We need far more than the HIDDEN_SSID fix CM7 required unfortunately
  • Bluetooth – Not working at all, not even to CM7 levels
  • TV Output – No one has gotten MHL fully working on any Samsung device yet to my knowledge. There’s some promising results from the I9100 community but it’s not there yet.

Known Issues:

  • Settings->Advanced will FC until I port over the relevant parts of the GalaxyS settings app from the GalaxySII

Pre-Installation Requirements

  • Important! An Infuse 4G with ClockworkMod recovery (CWM) installed.
  • 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.
  • Sufficiently charged battery, at least 50% is recommended.

How to Install Unofficial CM9 ROM on Infuse 4G

  1. Download the latest version of the ROM from the official development page.

    I’ve followed all the steps and now i’m stuck in at the samsung screen just like step 7. what do i do now, someone pls!

  • Shawn C.

    I got it installed and everything is working excpet my cellular signal, it’s like it isn’t even connecting to the AT&T service… any ideas?

  • alvarae

    ahhh!! everything was working perfectly until between steps 7 and 8 I did what it said in 7 but instead of getting the options to select mounts and storage I got static and colors on the screen. Now it won’t do anything but show the “samsung” or if i use the hard reset buttons I get the colors again.

    • Kapil

      Actually, by pressing that 3 button combo (of Vol up and down and Power) you have to enter the recovery mode. Try it again. Hold them a bit longer, you will eventually boot into cwm recovery. Then, you will have the mounts and storage option.

      • alvarae

        Thanks but I tried that like a million times. It wasn’t that there was a problem with the install. It looked like the choices were there just messed up and you couldn’t read them. I think that is what Gryffen420 was saying.

        I did finally get my phone back to factory by using xda forum titled “GTG’s Ultimate Unbrick – Return to stock – Working PIT included”
        *one note about that tho is to get your phone connected you had to take out battery, plug in USB cable, press up down volume button, and then replace the battery (don’t push power button) It worked a little bit different than listed in instructions.

        I wish this would have worked but I don’t think I am going to try that again lol

  • shelkov

    I tried my recovery thing 3 times. it keeps on saying signature verification not found. what do i do?

  • amreggie

    camera inop, and im a camera-aholic. heelllpppp :~)

  • Jeffery Price

    Day after the install my infuse stopped recieving text sms messages and phone calls what do i need to do to fix this issue?

    • Kapil

      You gotta wait for it then…. hopefully it will btw pretty soon.

  • ganu

    hello it getting signature failed

  • Divyesh28


    I just followed the process and at the end my infuse has again stucked on samsung logo

    What should I do?


  • Gryffen420

    an infuse 4G with clockwork recovery mod *and a gingerbread bootloader. Froyo bootloaders give you rainbows in bootloader menu and make it hard to choose the rom package.

  • Hovadrive

    This rom is really sweet so far , Thanks a lot Bro. I have a question how do i get to see the
    External_SD ,  

    • Rob Wolfenden

      It changed in ICS – the location of your external card is mnt/emmc/. External_sd is now just another folder on your internal storage.

      • Hovadrive

        OK. I see it now . Thank again . Running smooth so far

  • Sledgeharvy

    I have to admit, this is a pretty difficult process. So my suggestion to anyone, like the story suggests… MAKE SURE YOU’RE COMFORTABLE WITH THESE PROCEDURES… I can easily see how a novice would completely freak out after a couple of “Boot Loops”. After you’ve done this procedure a few times like I have ( I wanted to flash alternate kernels/modems to see which is best for my area and preferences, lol.) However, don’t let the complexity of these procedures deter you from enjoying the gorgeousness we call ICS… :-) Oh! By the way, Highest STABLE overclock is 1400mhz. Just saving you all additional headaches. Happy Modding!!

    • Mplsrover

      Hey, I was successfully able to install ics on my Samsung infuse 4G but google play -the app store isnot working. It says server error. I am connected to the Internet and the Internet seem to be working in browser and email.

      Any clue?
