After over 3 months of work, 2 hard-bricks (and a few soft-bricks) and a lot of coffee, it's time to release the first alpha version of CM9 for the Samsung Galaxy W (GT-I8150). This is very much still work in progress, but it should be decent enough now that it's usable, if you don't heavily rely on the not working stuff.

- 2012-04-01: CM9 alpha1 
- Initial release
- gapps UPGRADE REQUIRED
- gapps version 20120429
Please verify the md5sum to be sure you got the right one.
- gapps version 20120429
- Install AppBak from Market, run it and save a list of all your apps.
- Install SMS Backup and Restore from Market, run it and backup your SMS history.
- Install Call Logs Backup and Restore from Market, run it and backup your call log history.
- Boot into CWM5 recovery. Make a full backup. You will need this backup later if you decide to go back to your previous ROM and data.
- Use CWM5 or CWM6.
- Warning: Only use this recovery to flash CM9. Otherwise, you risk bricking your phone!
- Wipe data and cache.
- Flash update*.zip.
- Flash gapps*.zip. You must flash gapps after every upgrade to CM9 since /system is formatted, wiping your previous add-ons.
- Reboot phone.
- After you setup your Google account, reinstall the three apps from Market in order to restore most of your apps, call log and SMS history.
- Warning: Do not restore backup data of system apps!
- If you restore a bad backup with cached settings in telephony.db in data/data/com.*.*.telephony it can break MMS.
- It seems that restoring backups can also break Calendar sync.
Upgrades from previous versions of CM9 are the same process as install, except you do not need to wipe anything. Contrary to popular belief, you do not need to even wipe cache and dalvik-cache when upgrading between CM9 versions. You only need to wipe if you are doing a major upgrade, switching to a different ROM entirely, or attempting to fix bugs caused by bad backups or corrupt app data.
NB: Going from a ROM using 2.6 kernel to a 3.0 kernel, a full wipe is recommended though.
