First Alpha Build Of CM9 For Galaxy W Now Available For Download
By on April 2nd, 2012

Back in February, we had reported that one of the developers over at XDA forum is working hard on bringing CM9, based on Android 4.0 Ice Cream Sandwich, to the Galaxy W. The Galaxy W is a mid-range Android smartphone from Samsung, that has more than enough horsepower under the hood to run Ice Cream Sandwich easily, but won’t get the update for some reason. The developer had then posted a video showing CM9 in action of the Galaxy W, and had promised that he will soon release an alpha build when he gets most of the features to work.

Today, after 1.5 months, the developer – Arnie – has finally released a public alpha of CM9 for the Galaxy W (I8150) over at XDA forums. Since this is the first alpha build, there are some issues with it.

Below is a list of what works and what does not work in CM9 on the Galaxy W -:

What’s working:
Receiving and making calls
Proximity sensor
USB mass storage
HW accelerated gui
HW accelerated video

Not working:
USB tethering
No sound for calls over bluetooth
FM radio

So yeah, if the issues in the not working list are not a deal breaker for you, go ahead and flash the ROM on your handset. Since the Galaxy W will not get an official update to Ice Cream Sandwich, I will strongly recommend all Galaxy W owners to keep checking the CM9 thread over at XDA forums.

Below is an installation guide on how to install the CM9 on your handset -:

Step 1: Download CM9 from here, and Google Apps from here. Transfer both the files to your handset, before proceeding further.

Step 2: Download and flash this kernel via ODIN by using the One Package button. Make sure you also download and select this ops file in ODIN before flashing the kernel.

Step 3: Reboot your Galaxy W in recovery mode by using the Quick Boot app from Google Play. Now, use the Volume keys to navigate to the ‘Wipe data/Factory reset’ option and select it by using the Power key. Similarly, select the ‘format /system’ from the Mounts and Storage menu in CWM.

Step 4: Once you have formatted the /data and /system partitions of your handset, select the ‘install zip from SD card’ option and select the CM9 zip file that you transferred to your handset in Step 1.

Step 5: Repeat Step 4 again, and this time select the Google Apps zip file instead of the CM9 zip file.

After you have followed all the steps mentioned above, select the ‘reboot system now’ option in CWM and wait for your handset to boot. The first boot might take some time so please be patient. If for some reason your phone enters into a boot loop, re-do the steps mentioned above.
