CyanogenMod 10 (CM10) Alpha 4.1 for Samsung Galaxy W GT-I8150

What's working:
Audio
Receiving and making calls
GPS
Compass
Proximity sensor
Wifi
Bluetooth
USB mass storage
HW accelerated gui
HW accelerated video
Camera
Torch
Wifi/USB tethering

Not working:
The 2.6 kernel doesn't have vsync required for full project butter experience. The 3.0 kernel version has this though.
Camera is not working on the 3.0 kernel version.

Annoyances:
Artifacts in preview for panorama shots
Green color when taking pictures (saved picture is ok though)
USB tethering must be activated twice if it's the first boot
The fix for HSDPA causes an issue with APN's in Jelly Bean if you use SIM pin lock. To workaround that turn on and off airplane mode after entering pin code.

WARNING: Many apps will Force Close crash if you restore data from a previous ROM.

Install

1. Use CWM5 or CWM6.
   • Warning: Only use this recovery to flash CM10. Otherwise, you risk bricking your phone!
2. Wipe data and cache.
3. Flash update*.zip.
4. Flash gapps*.zip. You must flash gapps after every upgrade to CM10 since /system is formatted, wiping your previous add-ons.
5. Reboot phone.
6. 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.
7. 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
Upgrades from previous versions of CM10 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 CM10 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.
