Samsung Galaxy Ace : RAMDUMP ARM9 Mode Problem
But all these suggestions did not provide a solution to me. So what I did? I just pulled out the SD-card from its slot, then turn the device by pressing the Power button's on. Done! it solved my problem! SGA will boot properly, and after the Android home screen look good, you can safely insert the SD Card into it's slot.
Have a try, and give me your feedback
