I have been using Android HTC HD2 for quite some time. However, native Android phone like Samsung Galaxy S II does not have ClockworkMod Recovery Mode like Android HTC HD2. Samsung Galaxy S2 does have recovery mode but with less features compare to ClockworkMod Recovery Mode. Samsung Galaxy S2 has Android system recovery <3e> which can apply update from SD card, wipe data / factory reset and wipe cache partition only.
How to load into Samsung Galaxy S II Recovery Mode?
- Turn off SGS2.
- Press and hold down Volume Up + Home + Power buttons at the same time.
- Release all buttons when you see SGS2 Logo.
- Android system recovery will be loaded then.
