How To Upgrade Your Samsung Infuse To JellyBean (or Ice Cream Sandwich or Gingerbread)
(I am not that technical, and I did it...but it wasn't easy)


                    ** I am not responsible if you brick your phone while jailbreaking it/upgrading it. Take your chances, but you probably won't and now there is even "unbrick" software floating around that might help you if you do**

This article will attempt to tell you what you need to do to upgrade your Samsung Infuse by AT&T phone (by hacking/jailbreaking it)

If you're as tired as I am of waiting for AT&T to upgrade the Android software on your Samsung Infuse to Ice Cream Sandwich or Jelly Bean (or Gingerbread), you can take heart in the fact that you can do it yourself and take control of your phone as the administrator with full rights to install and remove any apps you want and new versions of Android. Its not that easy, but perserverance makes it possible (and you'll probably need about $10 worth of software, even though it is actually "free" to do it).

There is quite a bit of help and information on the web for flashing roms and upgrade to various levels of Android software...but I found it to be kind of a forest. It took me about a week to finally figure out all the information that is below. Hopefully this will help you. I am sure its not perfect, but it will probably make some things more clear so you can find your way.

First thing you need to understand is that in order to install newer Android software you'll need to get "root" access to your phone. (If you don't know--rooted means you have complete control over the phone. AT&T, Verizon and Sprint typically lock the phone so you can only do "so much"--rooting means you unlocked it so you can install whatever you want.)

There are two easy ways to acheive this--you can try using superoneclick with psneuter exploit or better yet, you can simply install new software that is already rooted over the old Android software . Personally, I think the second method is best. You can download ROMS that are made with Heimdall java installer and then put them on your phone but booting your phone into "download mode" while connected to your computer.

Heimdall will then just write new software over your old version of Android. For instance if you ever wanted to go back to AT&T's "stock" ROM (the one most customers of AT&T have on their Samsung infuse), you can go to this thread on the XDA forum and download it. BTW, its kind of an insurance policy to know about this link because if you ever need to have your phone serviced or just want to get back to where you were, there's the download for you.

The second thing you need to know is that your phone has two "modes"--there is the normal phone mode--the one you're used to seeing, and then there is the "Recovery mode". The recovery mode is what you use when you want to install new ROMs--it is kind of like DOS in the old days of the PC vs. Windows: DOS is recovery mode, the interface you're used to using is like Windows. The recovery mode that is installed on your phone by default is locked too. So you have to unlock it before you can install any software you want. (Otherwise you'll get errors such as "invalid signature" when you try to install a new ROM).

Most of the time, when you download a new ROM, you just need to plug your phone into your computer's USB port and copy it onto your SD card and then boot into the recovery mode (you press your volume up and down together while you press the power button to turn the phone on). Alternatively though, as mentioned above, if you have a heimdall rom, you can just install it from your computer. Realize again that you need to replace your recovery mode software for best results and maximum flexibility with ROMs -- if you don't you'll be stuck only installing Heimdall roms and there aren't that many. BTW, there is a Heimdall Rom that can be used to replace your recovery mode software on the Infuse. It makes life alot easier if you do it that way.

I have been using the Remics Jelly Bean Rom on my phone and it is very good--a huge improvement from anything I've used before. It really breathed new life into my phone. The only caveat though is that the camera doesn't seem to work as well as it used to with this ROM. Especially recording videos is messed up. They are working on fixing that though, so maybe by the time you read this it wouldn't be an issue any more but as of December 2014, it still is...

Here is a link to the download thread:

Good luck!

The instructions below are most helpful for people who have pre-gingerbread on their phone. The latest ROMs that AT&T ships are harder to crack with SuperOneClick in order to root them. I am leaving them up though because they still have some helpful information:

Things you're going to need-

ROM Manager (from Android Market)
1. SuperOneClick
2. Modified 3e Rom for the Infuse
3. RootExplorer (Paid software from Android Market - about $3.99)
4. Titanium Backup (Paid Software from Android Market)
5. A Gingerbread Rom (I'm going to talk only about the Cyanogenmod Rom) .
6. Google Apps Rom (A seperate Rom that contains things you'll want like GMAIL and Android Market)

Get Titanium backup and install/backup your phone. That's for your protection and will make it easier to recover after you upgrade your ROM. One thing you should realize is that your going to loose all the contacts, apps, settings on your phone if you upgrade and don't have backups. As far as contacts, if you're using gmail, just make sure you go into the settings and turn on sync contacts so that they'll be backed up in the cloud. There is also an option in the contacts app that lets you back up all of your contacts to your SD card. That's handy too. Also, worst case scenario is that you need to download/reinstall all of your apps from the Android Market/Amazon Android App Store (here are some that I recommend), and for the sake of a clean start, you might want to do that, but if you backup and then restore, you'll have everything back.

1) You'll need to get root access to your phone (just doing this step will give you much better control over your phone and is worthwhile). To do this you're going to need this SuperOneClick software--it makes it pretty easy to do it. Just download the software to your computer, turn on USB debugging on your phone (its in the menu) and hook your phone up to the USB port. After your computer recognizes the phone, you select the right kind of exploit from a dropdown and then click a button and the software does the rest. (more below) I used the psnueter exploit...the other ones didn't seem to work. Once you get root access you'll notice you have an extra "Superuser" icon in your apps list. Run it and look around--kind of cool for instance you can delete AT&Ts extra apps by "freezing" them.

2) You'll need to install a "modded" 3e recovery. This is a little bit tricky, but not too bad. First of all thoough, you'll need RootExplorer software. If you skip this step, you'll get an error message about your software not being signed when you go to flash the ROM. "e:signature verification failed" or something like that. When you install this modified recovery file, it will ignore the signature and install anyway. The reason you need rootExplorer software is because it will let you go into the android system folders (in this case, namely system/bin) and change the file out and then reset the permissions on the file. I know that sounds complicated, but there is a video about how to do it:

 3) You'll need ROM Manager to install ClockWork Mod Recovery. Its an app you'll download from the Android Market. Get the app, install it, run it and then you'll see the first thing in the list is to install ClockWork Mod Recovery. Click that button and reboot as instructed. You'll need to use your volume key down to select "reinstall Rom" If you didn't do step 2, it won't really work.

4) You'll need to download an Android Gingerbread ROM to use (one that is compatible with the Samsung Infuse!). Again, I recommend CyanogenMod 7 for Samsung Infuse. There are plenty of other choices though. Only thing about CyanogenMod is that it doesn't install the google software (including things like Android Market that you're probably going to want). You'll download and install that seperately. Download the ROM (the download is linked from the first message at the top of the thread I am linking you too here--you can click for a directory of the builds and get the one with the newest date or just take the main one that's linked), the file is about 98 megs. Rename the file "update.zip" and put it on your SD card. Use your ROM Manager to choose to install from the SD Card, and then reboot. Click on Reinstall Rom by using your volume down key and then click the power button to make it "go"...

5) You will get to the Samsung Screen and it will freeze there. Don't panic. Go back to the ROM install screen and choose REINSTALL again. Reboot, take the battery out and it should work the next time. You should then get your Infuse to boot up and you'll see the Cyanogenmod 7 splash screen...and your phone will come up. You'll notice alot of cool stuff, and alot of things missing. Again, one of the missing things you'll probably want is the "Google Apps"--you can download those as a ROM. You might also want to go to SWYPE.com and get onto the SWYPE beta so you can have SWYPE back on your phone.

If you do brick your phone (and you've pulled the battery out and reinstalled a couple of times, search for unbrick my android phone. You may also get help by using the Odin software.
