XXDLI4 — Android 4.1 Jelly Bean Update for Samsung Galaxy S3, i9300

“Let’s do some work today, make a new firmware, then do some work again tomorrow, then make yet another new firmware after that” seems to be the motto at Samsung regarding the Android 4.1 Jelly Bean update for the Galaxy S3, as every single day we are seeing a newer Jelly Bean firmware getting leaked for the device, which is getting tiring to see, but also assures us Samsung is working around the clock on the update.

“If you have the T-Mobile Galaxy S3, you can try out its leaked Jelly Bean firmware → here. Bell Galaxy S3 (i747M) owners can try out the leaked Jelly Bean update → here.”

Today it’s the XXDLI4 firmware that has been leaked, an update over the XXDLI3 firmware that came out yesterday, and we of course have made a full step-by-step guide on how you can try the latest Android 4.1 firmware out on your Galaxy S3. You will need a microSD card inserted in the phone to be able to install the update.

Keep in mind that this is a leaked pre-release firmware and has not yet been officially released by Samsung and hence could have some issues, so you should wait for the official update to come out if you’re not comfortable with manual flashing. But if still try it out, you can always flash back to an Android 4.0 firmware later if needed.
