Install SlimBean build 5 based on Android 4.2.2 JB for Samsung Galaxy S I9000

The SlimBean custom ROM based on Android 4.2.2 Jelly Bean has been released for the Samsung Galaxy S model number I9000. Use this tutorial and you will easily flash the new OS on your smartphone at your first attempt.

This is a guide for advanced Android users that want to tinker with their smartphone’s OS. SlimBean ROM is a lite version of a full custom Jelly Bean ROM. It measure only 85MB and its main features are as following: enhanced Easy Selector in MMS, Enter key is now shown by the keyboard, added DeskClock support added, multiple bug fixes for the stock AOSP features, support for DCHSPAP, fixed several memory leaks, added multiple tweaks for the core framework etc.

Installing this update will not flash a stock Samsung version of Android 4.2.2 as the official OTA Update for this particular device the release of OTA Updates have been discontinued.

In order to make sure that you successfully flash the new OS, you should first take a look at the preparation guide below. Make sure to read the guideline before continuing to the tutorial. Here’s what you need to know:

  • use this tutorial only with the Samsung Galaxy S model number I9000. Check the phone’s version by going through Settings and About phone menu. Don’t try to install this version of SlimBean ROM on any other Android device.
  • your phone has to be rooted and running CWM or TWRP Recovery. I have used the CWM Recovery for this tutorial but, the TWRP version will work with this guide, as the instructions are very similar and you will be able to figure out the menus you need to access.
  • use the custom Recovery mode to create a full NANDROID backup of your current OS. This will set a restore point that can be used in case SlimBean doesn’t boot after installation.
  • in the tutorial you’ll find a step that will ask you to wipe data/ factory reset the phone, which is why the /system partition will be removed in the process. However, the contents of the internal SDcard won’t be affected by this tutorial.
  • backup SMS, Call logs info and APN Internet Settings using the following tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access is required for some of these applications.
  • sync your Contacts info with your default Gmail account so that you will not lose any important data in the process.
  • enable USB debugging option from the Developer Options menu.
  • make sure that the phone’s battery has enough power left before switching off. In case the device powers off in the middle of the updating process, you will be forced to repeat the entire tutorial once again. Worst case scenario, the phone will be bricked.
  • use this guide only if you want to test a brand new custom ROM and you know what you’re doing.
  • don’t blame us in case you lose any important data in the process or you manage to brick the phone.
  • read the entire post and ask for extra help in comments if you cannot complete the installation.

These were all the guidelines that you had to go over before continuing to the tutorial part of this post. Make sure that you don’t skip any actions listed below, as that will result in failed installation attempt.

How to install SlimBean Android 4.2.2 JB custom ROM for Samsung Galaxy S I9000:

  1. Download the SlimBean 5.60 custom ROM from HERE. Save the zip file on your PC and don’t extract its contents.
  2. Download Gapps for this ROM from HERE. Don’t unzip and place the file on your computer.
  3. Connect the smartphone to your PC via USB data cable.
  4. Move both downloaded files onto you Galaxy S’ internal SDcard. Disconnect the device from PC when the files are copied successfully.
  5. Power off your device completely.
  6. Boot it into Custom Recovery mode like this: press and hold Volume Up, Home and Power buttons simultaneously. I’ve used CWM Recovery for this guide, but the TWRP version should work just fine with this guide.
  7. When you’re at the main screen of Recovery Mode, select ‘backup and restore’ option and create a full NANDROID backup of your current OS.
  8. Select ‘wipe data/ factory reset’ option now and confirm this process.
  9. Select ‘install zip from sdcad’ and then ‘choose zip from sdcard’. Find the SlimBean zip file. Confirm that you want to install it.
  10. Now that the ROM has been flashed, select ‘choose zip from sdcard’. Find the Gapps zip and install it.
  11. After you have successfully flashed the new ROM, you can return to the first Recovery screen.
  12. Select ‘reboot system now’ option and wait for the first boot process of this new OS to complete.
  13. The SlimBean ROM boot shouldn’t take more than 10 minutes to complete. Enter your Google Account info and that should be it.
  14. Test all the new features of this ROM and then tell us in comments how’s your smartphone behaving with it.

These were all the steps that you had to take in order to successfully install the custom SlimBean Android 4.2.2 ROM for your Samsung Galaxy S smartphone.

NOTE that in case the phone doesn’t complete the first boot process or it enters into a boot loop, then you will need to repeat the entire tutorial once again starting with step 5. Make sure that the ROM and Gapps files have been successfully and copied entirely on your phone’s internal SDcard. Also, make sure to apply step 8 and factory reset the phone.

If you don’t like this new OS or the installation process gives you too much hassle, then you should restore the NANDROID backup file of your previously installed ROM. Use the same Custom Recovery mode and the ‘restore’ option to install your former OS version.

Remember that this is only a custom ROM and not an official update by Samsung. It will only install a port of Android 4.2.2 ROM and you might be affected by bugs and errors. But, if you like the Jelly Bean operating system then it will worth having to deal with these types of problems.

Another bad point about this custom ROM is that its battery life might be diminished as the base ROM is Android 4.2.2 Jelly Bean AOSP and it requires much more power than ICS or Gingerbread used to.
