I9300XXUFMB3 – Galaxy S III Android 4.2.1 Jelly Bean LEAKED firmware

We of SamMobile would like to give you the latest I9300XXUFMB3 – Android 4.2.1 Jelly Bean test firmware for the Galaxy S III. Big Thanks to forum member Saturn from XDA-Developers who made this possible by giving us the dump files from his device.

Android 4.2.1 is still under testing phase by Samsung and they will release the official final Android 4.2.1 Jelly Bean update for the Galaxy S III after the launch of the Samsung Galaxy S IV. We wanted to give Samsung’s hardcore fans a sneak preview of what Samsung is up to in their dev center.

New enhancements in I9300XXUFMB3 FW:
- Android 4.2.1 – JOP40D
- Improved Ripple effect on Lockscreen
- New Android 4.2.1 Lockscreen with widgets
- Daydream (Settings>Display)
- New Additions in Notification Center
- Notifications are more actionable
- Voice Command (Let’s you control various parts of the phone using voice commands)
- Found more? Tell us about them in the comments below!

WARNINGS:
We have repackaged this firmware into an ODIN Flashable firmware ourselves from the dump files we took from Saturn’s device. This firmware will increase your binary counter, if you don’t know what this means then don’t flash this firmware. This Firmware will also change your device status to Modified. This firmware doesn’t contain any Modem so the Modem you are using before flashing this firmware will remain. This is a PRE-RELEASE version so not official from KIES. As this is a PRE-RELEASE firmware some minor bugs are to expect.

We have FULLY TESTED this firmware and this firmware works perfectly as any other official firmware.

There is a fix for the Messaging app closing provided that you made a backup of all your SMSes before flashing this firmware. The logs indicate that the Messaging app tries to upgrade the mmssms.db app from version 58 to 61 and fails because some tables / columns already exist.

If you have a backup of your SMSes (or you don’t want to wipe the phone but don’t care about the SMSes) then you can remove the file – of course, you loose all SMSes.

You need to have the phone rooted, and delete the file from here:
/data/data/com.android.providers/telephony/databases/mmssms.db

If you want to keep the SMS-es, the only solution is to take the db on your PC, use an sqlite editor to drop the tables / columns that are reported in the logcat. I didn’t try this one ..
