Booting Android from an SD card has become somewhat of a trend in recent weeks. In most cases, it’s been on devices that don’t run Android as a stock OS, and users have the option to run Android and the device’s stock OS. Now, similar functionality is available for the Samsung Wave.
XDA Senior Member hero355 wrote a tutorial on how to get Android booting from the Bada device’s SD card. The tools to do so were created by XDA Elite Recognized Developer Rebellos and XDA Forum Member volk204, which you can find more info on here. There are plenty of other members and developers who contributed as well.
The process itself isn’t overly difficult, but does require that users pay attention. There are several zips that will need to be downloaded and flashed in recovery. During the process, users are given the choice as to how much they want to use for internal storage for the Android ROM they’re flashing, so that the SD card can be properly partitioned.
Once it’s all said and done, users have the option of booting into Bada or Android. There are some issues, such as no modem functionality or microphone, among others. So it’s not exactly daily driver status just yet. Since Bada still works, though, it allows users to get the Android experience without losing functionality entirely.
