The stock ROM of Galaxy Ace GT - S5830i doesn't belong to me, it belongs to the respective owner who compiled it. All credits to the person who compiled the Ace GT - S5830i ROM. I am just giving a simple tutorial and re-posting the GT - S5830i ROM here as it is very difficult to find the correct working stock ROM.

Note: Your phone should have a minimum 85% of Battery before you start the operation.
