I am using a Samsung Ace S5830i since 2 years now with a custom ROM : Ace-i-Sure 12.0, all worked properly.
Yesterday I installed an app, I do not remember which one but I think it was a game, then my phone rebooted and looped on the boot animation.
I am used to unbrick my phone and change ROM so it did not scared me.
I tried to flash the stock ROM I used to flash everytime my phone has been bricked. Flashing went OK but my phone kept looping.
I tried to wipe data/factory reset but nothing changes.
I tried with another stock ROM found here and nothing changes either.
Do you know what might causes this problem ?
