I have a problem with my phone some time ago it have a bootloop (stuck when showing galaxy win gt-i8552 screen)
after a tried flash the stock rom few times but doesnt work (i bought this device on malaysia and stock rom i used was the indonesia one ,do i must use the malaysia stock rom?)
after that i try flash a custom rom but it doesnt work too
I also hear some high-pitched electric sound (like iiiiiiiiiiiing) from the back side of device near the sdcard slot but it doesnt appear when im in recovery it only show when the screen is showing the galaxy grand win screen
Does it was hardware problem?
