Update AT&T Skyrocket to Jelly Bean with Slim Bean ROM


A new Android 4.1 Jelly Bean custom ROM has made its way to the AT&T Galaxy S2 Skyrocket – Slim Bean ROM, which features Android 4.1 in a really lightweight and slim package, with no useless apps or bloat, small memory footprint and light on resources, and also featuring some great customization features as well.

“Jelly Bean custom ROMs for the T-Mobile Galaxy S2 can be found → here.”

Keep in mind that this is not an official Samsung ROM. It’s a custom ROM that is under development and may have a few bugs and issues, and some things may not work properly and some stock Samsung ROM features will not be available.

Currently, the following issues are present in the ROM, quoted from the source page (where the most updated list of issues can be found):

lockscreen weather may not work

Let’s take a look at how Slim Bean ROM can be installed on the AT&T Skyrocket.


This ROM and the guide below are compatible only and only with the AT&T Galaxy S2 Skyrocket, model number SGH-I727. It’s not compatible with other US variants of S2, the Epic 4G Touch, and AT&T Galaxy S2 or any other device. Check your device’s model number 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.

How to Install Slim Bean ROM on AT&T Skyrocket

  1. This procedure will wipe all your apps, data and settings. Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    NOTE: Don’t forget to at least note down your network’s APN settings, which are required to make mobile data work. Go into Settings » More » Mobile Networks, click on the APN that is in use, then note down the setting for each field. While APN settings should be automatically restored from network, you can enter them manually if needed to make mobile data work. You can also find your APN details → here.
  2. [Important!] Install the ClockworkMod (CWM) Touch recovery on the phone by following the guide → here
  3. Download the latest version of the ROM from the source page.
  4. Download the Google Apps package. This will install apps like Play Store, Gmail, etc. which are not present in the ROM by default.
    Download Gapps  |  Filename: slim_gapps.zip
  5. Copy the ROM and Gapps files to the internal SD card on the phone (do not extract them).
  6. Turn off the phone, then boot into recovery mode. For this, press and hold these 3 buttons together until the screen turns on: Volume UP + Volume Down + Power. Phone will boot into CWM recovery.
  7. 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. Go back to main recovery menu after backup is complete.
  8. Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete (this will not erase your personal files on the SD card).
  9. Now select install zip from sdcard, then select choose zip from sdcard. Scroll to the ROM file on the SD card and select it. Confirm installation by selecting Yes – Install _____.zip on the next screen. The ROM will start installing.
  10. After ROM installation completes, select choose zip from sdcard again, then select the slim_gapps.zip file to install the Google apps package.
  11. After installation is complete, select go back then select reboot system now to reboot the phone and boot up into Liquid ROM.
    NOTE: If you want to go back to your previous ROM, boot into recovery (like you did in step 6), select backup and restore then restore your previous ROM by selecting it from the list.

Slim Bean ROM, based on Jelly Bean Android 4.1 is now installed and running on your AT&T Galaxy S2 Skyrocket. Visit the official development page for updates and more info. Share your thoughts on the ROM in the comments below.

    When trying to use the google search bar I get the
    dreaded “‘unfortunately google search has stopped” message. I tried to “clear data” and “clear cache” in the apps setting page for both google search and google framework, but no luck.

    Any ideas?

      Answering my own question and logging here in case others run into the same.
      1) Delete widget
      2) Delete Google Search app
      3) Download fresh Google Search app from Play Store
      4) Add widget
      5) In app settings, clear all data for Google Search
      6) reboot

      The above steps worked for me! Google Now and search both working.

    Installed Slim Bean 2.9 with addons upgrades to 2.9 on S2 skyrocket and works great. I think is faster than tge ICS. The few things that I noticed that dont work.perfect are:
    1. When geting a call from a contact that has an assigned ringtone sometimes it doesnt ring that ringtone.
    2. Email app doent refresh by itself. I have same emails as before only getting new ones if I get to that email account it than refreshes. For me this is important to work.
    Maybe this doesn’t work after th upgrade from 2.8. I’ll have to check online

  3. Im having trouble, first off the resolution seems to be off and the home button does not work. I have the galaxy s2 sgh i727. The google play store does not work either. HELP!
