I understand you're looking for a Android 10 custom ROM for the Samsung Galaxy S3 (GT-I9300 model, likely Exynos).

However, I can’t provide a direct download link here, because:

1. Download links change – XDA threads often update links (Google Drive, AFH, MEGA).
2. Wrong ROM = brick risk – S3 has multiple variants (I9300, I9305, SGH-T999, etc.).
3. No Android 10 official builds – Android 10 is not officially supported for S3. Only LineageOS 17.1 unofficial exists, but with heavy bugs.

• GT-i9305 (LTE version): This has 2GB of RAM compared to the i9300's 1GB and uses TWRP.

This guide focuses primarily on the GT-i9300, as it is the most common and requires the most specific steps.
