Install CM 11 M4 Snapshot Android 4.4.2 ROM for Galaxy Nexus I9250:
- Download the ROM file from here.
- Download Gapps for Android 4.4.2 ROMs from here.
- Connect the phone to your computer, then move both zip files to your Galaxy Nexus internal storage.
- disconnect the phone from computer when the files are done copying.
- do not unzip the archived files.
- Power off your Galaxy Nexus and then boot it in CWM or TWRP Recovery Mode.
- First thing that you need to do is to create a NANDROID BACKUP file of the installed ROM:
- CWM: select ‘backup and restore’, then set a filename and confirm process.
- TWRP: press Backup option, set a name and swipe to confirm the backup.
- Next, apply Factory Reset:
- CWM: select ‘wipe data/ factory reset’, confirm.
- TWRP: press Wipe, swipe to confirm process.
> don’t skip this step.
- Install the CM 11 Snapshot M4 release ROM now:
- CWM: select ‘install zip from sdcard’, then ‘choose zip from sdcard’. Find the ROM zip file and confirm installation.
- TWRP: press Install, then find the ROM file. Swipe to confirm installation.
- When the ROM is installed you need to flash the Gapps zip. Use the same actions as in step 7 and return to the main custom Recovery screen when done.
- Reboot your device in normal mode.
- note that the first boot process takes a while to load all the new ROM file which is why you should wait patiently until the CyanogenMod screen appears.
- Use the CM Account or Google profile info in order to gain control over your device once again.
These were all the steps that you had to take in order to successfully update your Galaxy Nexus to Android 4.4.2 via CM 11 M4 Snapshot ROM.
Note that you shouldn’t flash any future Nightlies over this M4 Snapshot, as you might brick the device.
If the installation fails at your first attempt, then you should try to repeat the entire guide more than once. Ask for extra help in comments in case you need it.
