Samsung is yet to release its latest official Jelly Bean firmware (Android 4.2.2) for the first generation Android devices including the Galaxy S I9000. However, the S I9000 users can now enjoy the most stable build of Android 4.2.2 custom firmware, thanks to the final release of CyanogenMod 10.1 ROM (CM10.1).
The final build of CM10.1 ROM is based on the original Android Open Source Project (AOSP), which includes the latest security fix for Android 4.2.2 and can be installed via custom recovery tools such as ClockworkMod (CWM) or TWRP. CyanogenMod is designed to increase performance and reliability over Android-based stock ROMs from vendors and carriers such as Google, T-Mobile, HTC, Samsung, etc.
Note: Instructions provided in this guide are meant for reference purpose only. IBTimes UK reminds readers it will not be held liable if device is damaged or bricked during or after firmware installation. Users are advised to proceed at their own risk.
- The Final CyanogenMod 10.1 ROM and the instructions are meant for the Galaxy S I9000 model only. Do not attempt installing this firmware on another variant or device, as it may inadvertently hard-brick or damage the device. Verify device model number by navigating to Settings > About Phone
- Back-up data and settings using a recommended custom recovery tool such as ClockworkMod (CWM) or TWRP
- Verify appropriate USB drivers are installed on the computer (download Samsung Galaxy S I9000 USB drivers)
- Ensure USB debugging mode is enabled on phone by navigating to Settings > Developer Options (if device is running Android 4.0 or later) or Settings > Applications > Development (if device is running Android 2.3 or earlier). If device is running Android 4.2, perform the following steps:
- Go to Settings > About Phone
- Scroll to bottom of screen and select Build Number
- Tap phone's Build Number seven times to unlock or reveal hidden developer options under Settings. Then select checkbox to enable USB debugging mode under Settings > Developer Options
- Ensure phone has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing ROM
- Ensure device is unlocked (not locked to specific carrier) and rooted with ClockworkMod Recovery (CWM) installed
- If device is stuck at booting or experiences boot loop issues, Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting
- Allow newly installed ROM to stabilise for five minutes before using the device
- If a Status 7 error message flashes while installing firmware, it could be due to an incompatible device or absence of a necessary kernel (for instance, a Jelly Bean Kernel must be installed before installing any Jelly Bean ROM)
