Reviving the Legend: Installing Android 10 on the Samsung Galaxy S3

The Samsung Galaxy S3 (GT-i9300) is one of the most iconic Android devices in history. While the official software support ended years ago (stuck on Android 4.3 Jelly Bean), the developer community has kept this device alive.

Installing a modern operating system like Android 10 on hardware from 2012 is a testament to the modding community, but it requires specific knowledge about custom recoveries, file formats, and device variants.

1. Know Your Device Variant

Before downloading anything, you must confirm your exact model.

  • GT-i9300 (International): This is the standard Galaxy S3. It uses a custom recovery format called LZMA.
  • SCH-i535/i747 (US Variants): These use TWRP and require different files.
  • 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.

Troubleshooting

  • Bootloop after flash: Reboot to TWRP → restore nandroid backup or reflash ROM + vendor files → wipe caches.
  • If Wi‑Fi/Cell not working: ensure correct modem/baseband firmware and vendor blobs for your model.
  • App crashes/Google services issues: flash compatible GApps for Android 10 or try micro variant.

Phase 2: Wipe and Flash

  1. In TWRP, go to Wipe > Advanced Wipe.
  2. Check: Dalvik / ART Cache, System, Data, Cache. (Do not wipe Internal Storage if your ROM is on there).
  3. Go back to Install.
  4. Navigate to your microSD card where you saved the lineage-17.1-UNOFFICIAL-i9300.zip.
  5. Select the ROM zip. Add more Zips -> Add the open_gapps-arm-10.0-pico.zip.
  6. Swipe to confirm flash.
  7. (Optional) Flash Magisk for root.
  8. Tap Wipe cache/dalvik.
  9. Reboot System.

First boot takes 10–15 minutes. Do not touch the phone.

Alternative Android 10 ROM Links (If Lineage is too heavy)

ROM: crDroid 6.x (Android 10) Link: https://github.com/crdroidandroid/android_device_samsung_i9300 (Check Releases section) Why use it? It has more customization (status bar tweaks, launcher mods) but slightly lower benchmark scores.

Prerequisites

  • Windows PC: Essential for the ODIN flashing tool.
  • USB Drivers: Install Samsung USB Drivers on your PC.
  • ODIN: Download the latest version of the Odin3 tool.
  • Custom Recovery: For the GT-i9300, you usually need PhilZ Touch or a compatible version of TWRP (often specifically v3.2.1-0 or modified versions).
  • The ROM: Search XDA Developers for "Galaxy S3 LineageOS 17.1" or "Android 10 Galaxy S3."

Step 2: Flash the Custom Recovery

  1. Open ODIN on your PC.
  2. Connect your S3 via USB. You should see a blue or yellow COM port box light up.
  3. Click the AP (or PDA) button and select the custom recovery file you downloaded (usually a .tar.md5 file).
  4. Ensure only "Auto Reboot" and "F. Reset Time" are checked.
  5. Click Start. The phone will reboot.
  6. Crucial: immediately after the phone reboots, hold *Volume Up + Home +
