The Samsung Galaxy S2 is one of the most popular and the highest selling Android smartphone of 2011. The phone is selling like hot cakes all over the world, and is also a developer community favorite with more than 50 Custom ROMs available for the handset.
Due to the large number of ROMs available for the handset, it may become cumbersome for a user to try out each and every ROM personally.
Now, one Galaxy S2 developer – HellCat – has made an application which allows users to easily dual-boot between two different custom ROMs, making ROM hopping easier. This app will allow SGS2 owners to dual-boot between their existing ROM and the new ROM they are trying out. So, if in the middle of the day, they don’t like the new ROM, they can simply boot back into the older ROM they were earlier using.
This app will be a boon for every SGS2 user who keeps switching between a Samsung based ROM, for its features, and an AOSP ROM, for its simplicity and customizability. Since the app is still in early stages, it might have a few rough edges. Galaxy S2 users interested in dual-booting ROMs on their handset should keep in mind that they must have a rooted phone, with a kernel which must support dual-boot.
Also, after they setup dual-boot on their handset, they cannot access the Recovery menu by using the Volume Up. + Home + Power button combo. This key combination will allow them to boot into the second ROM they have installed. To boot into recovery, they need to connect their phone to a USB charger.
