Galaxy Nexus I9250 is among the few Jelly Bean devices to receive the latest Android 4.4 KitKat update, thanks to the release of CyanogenMod 11 (CM11) ROM by the industrious XDA recognised developer, PlayfulGod.
The CM11 ROM is built on the original Android Open Source Project (AOSP) and the new Android 4.4 KitKat update brings a whole new range of exciting features including faster multitasking, enhanced Google Now, immersive mode and smarter Caller ID.
With Samsung unlikely to release any official Android 4.4 firmware for Galaxy Nexus I9250, the release of Android 4.4 based CyanogenMod 11 ROM gains precedence. Head over to the XDA developer source page (check the link at bottom) to learn more about the features and enhancements ported into this ROM.
Interested users can follow our step-by-step guide to install Android 4.4 KitKat on Galaxy Nexus using CM11 ROM. IBTimes UK reminds its readers that it will not be held liable for any device damage during or after firmware installation. Users are advised to proceed at their own risk.
- The Android 4.4 CyanogenMod 11 ROM and the instructions given in this guide are meant for the Galaxy Nexus I9250 model only. Verify device model number by navigating to Settings > About Phone.
- Back up data and settings using a recommended custom recovery tool, like ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup. In Recovery, choose Backup and Restore and tap Backup.
- Verify correct USB drivers for the phone are installed on the computer (download Galaxy Nexus I9250 USB drivers).
- Ensure USB debugging mode is enabled on the phone, by navigating to Settings > Developer Options (NOTE: Tap the phone's Build Number seven times to unlock or reveal the hidden Developer Options under Settings.) Then select the checkbox to enable USB debugging mode under Settings > Developer Options.
- Make sure the phone has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing the ROM.
- Ensure the device is unlocked (not locked to a specific carrier) and rooted with latest ClockworkMod (CWM) Recovery (v18.104.22.168) installed. Alternatively, install CyanogenMod 10.2 Nightly which includes CWM recovery v22.214.171.124. If you are installing the CWM recovery for the first time, check out the video tutorial below,courtesyof The Android Soul:
- If the device is stuck at booting or experiencing boot loop issues, perform Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
- Allow newly installed ROM to stabilise for five minutes before you start working on it.
