CyanogenMod 10 for Samsung Galaxy S Plus GT-i9001


Looking to get a taste of Android 4.1 Jelly Bean on your Samsung Galaxy S Plus (i9001)? You can now have it thanks to CyanogenMod 10 (CM10), the most popular custom ROM out there and now based on Android 4.1, ported over to the i9001 by XDA Senior Member Doomsday94.

Jelly Bean brings many new features to Android, including a smooth and fluid interface thanks to the “Project Butter” enhancements, redesigned notifications menu with expandable and actionable notifications, the new Google Search experience with voice recognition, smart and accurate keyboard, offline voice typing, faster browser, and lots more, which CM10 builds on and adds faster performance and some useful customization options as well.

Keep in mind that this is not an official Samsung ROM but an unofficial custom ROM that is in development, and it may have a few issues present and some things may not work properly. Also, since this is an unofficial custom stock Android ROM, Samsung specific features will not be present in it and some apps like the camera may be different.

The following things current work/do not work in the ROM, quoted from the source page (where the most updated list of issues can be found):

What Works (as of 23 Sept ’12):

Video (sometimes youtube crashes)
Receiving and making calls
Proximity sensor
USB mass storage
HW accelerated gui
HW accelerated video
60% project butter

Not Working:

headset audio
full butter experience
many other things

Let’s take a look at how CM10 can be installed on the Galaxy S Plus.


This ROM and the guide below are compatible only and only with the Samsung Galaxy S PLUS, model number i9001. It’s not compatible the GT-i9003, I9000 or with any other device and may render an incompatible device unusable. 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 exactly what you are doing. If any damage occurs to your device, we won’t be held liable.

How to Install CM10 on Galaxy S Plus I9001


  1. 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.
    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. Remove SIM card lock, if you have set it earlier. Go here: Settings » Location and Security » Sim card lock » checkbox should be clear (not selected).
  3. Install TWRP Recovery on your phone by following the guide → here. You can also use ClockworkMod recovery, though this procedure will assume you are using TWRP recovery.
  4. Download the latest version of the ROM from the source page.
  5. 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:
  6. Copy the two zip files downloaded in step 4 and 5 to the internal SD card on the phone.
  7. Now, we need to boot the phone into TWRP recovery. To do so, turn off your phone. Then, press and hold the Volume Up + Power buttons together, and let go of the buttons as soon as the Samsung logo shows up. Then, as soon as an icon showing “an Android in a box” comes up, press the Menu button (the button on the left of the center/home button) to enter recovery.
  8. Now, tap on Backup, then slide the blue circle button at the bottom to the right to start backing up your current ROM, so that you can restore it later if something does not work out with the new ROM. After backup is complete, go back to the main menu by clicking the home button at the bottom left of the screen.
  9. Select Wipe, then select Factory Reset and then confirm the data wipe. This will not wipe your internal SD card’s contents, so do not worry. Then, go back to the main menu by clicking the home button after wipe is complete.
  10. Select Install, then browse and select the ROM file on the SD card. Confirm installation to flash it.
  11. After installation of ROM is complete, repeat step 10, but this time select the file you downloaded in step 5 above. Confirm again to install the Gapps package.
  12. After installation is complete, select the Reboot system button to reboot the phone and boot up into CM10. First boot will take up to 5-7 minutes.

NOTE: To go back to your previous ROM, boot into recovery (with procedure explained in step 7), select Restore, then restore your previous ROM by selecting it from the list. Then reboot the phone after restore is complete.

CM10 based on Android 4.0 is now installed and running on your Galaxy S Plus. Visit the development page for more info and to get the latest updates on the ROM. Share your thoughts on the ROM in the comments.
