Samsung Galaxy S was the first flagship device from Samsung. It was launched a long time ago so obviously Samsung did not update it with the Ice Cream Sandwich and the Jelly Bean OS. This did not stop the developers from creating the custom ROMs for this device. XDA developers have managed to create the CM 10.1 custom ROM for this device running on the Android 4.2.2 OS. It should be noted that this tutorial must only be used for Samsung Galaxy S i9000 and not any other firmware or variants. Follow the instructions given below.
- Samsung Galaxy S i9000 must be rooted
- Custom Recovery installed on the Samsung Galaxy S i9000 (eg CWM or TWRP)
- CM 10.1 zip file
- Gapps zip file
- Make sure that USB debugging is enabled on the phone.
- Then create a Nandroid backup from recovery, in case anything goes wrong.
- Download the CM 10.1 zip file and Gapps zip file and place it on the SD card of the phone.
- Switch off the phone and boot the phone into Recovery mode.
- Then perform full data wipe task. To do so, click “Wipe Data/Factory Reset”, then choose “Yes” on next screen to confirm.
