I9300XXUFMB3 – Galaxy S III Android 4.2.1 Jelly Bean LEAKED firmware

Follow: Firmware news Firmware news
fruity jelly beans

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.

Firmware Details
Android Version: 4.2.1 – JOP40D (Jelly Bean)
PDA: I9300XXUFMB3
CSC: I9300OJKFMB3

Carrier: Unbranded
Changelist: 171637
Build Date: 19th February 2013

Flashing Instructions:
- Unzip the file

- Connect phone and wait until you get a blue sign in Odin
- Add I9300XXUFMB3_I9300OJKFMB3_HOME.tar.md5 to PDA
- Make sure re-partition is NOT ticked
- Start flash, sit back and wait a few minutes.
- If you encounter any issues with the firmware (Any FC, Bootloop etc)
- Boot into recovery mode (Home+power+vol up)
- Choose to wipe/factory reset. (THIS WILL ERASE ALL OF YOUR DATA INCLUDING YOUR INTERNAL SD CARD!)
- Then choose reboot and you should be good to go!

    The only reason people are having issues with Messaging FC’in or lag is because they are refusing to follow the instructions.

    RULE ONE:

    Read the instructions

    RULE TWO:

    Read the instructions

    RULE THREE:

    Don’t flash if you haven’t followed step 1 and 2

    You all need to read the instructions properly, for all thouse having problems with messaging app force closing then you will need to do a factory data reset. Note that you will lose all your apps, messages, contacts and so forth but it will fix the problem.

    Leak 4.2.1 installed on my GS3 (no brand) and found few bugs: I had to remove the Kaspersky antivirus as it was crashing all the time. SMS messaging (default app) don’t open and crash (with 3 strange vibrations). Gallery don’t open if I try to share a pic from inside an app. I cannot change/choose anymore the shortcut’s apps in the lock screen. Developer option disappeared from the Settings menu. I know that a factory reset will fix some of those issues but I wonder if the battery will perform better too, as for now its drain is unsustainable. Keep testing ;)

    Hello ajesh7s,

    I can confirm both bugs.
    You can enter the Google Now menu by clicking very fast at any option of the menu. Once you are at the setting you can change the settings.
    My biggest problem is the battery consume. I use the modem that comes with the Build Numer JZO54K.I9300XXEMB1.

    Flashed my phone with this, but unfortunately it made my phone heat up pretty quick every time I use wifi and caused significant battery drain(before, my S3 can last for a day with a single charge, but after flashing to 4.2.1 I had to charge twice a day). But I can feel the ‘buttery’ UI and enhanced performance. Reverted back to 4.1.2 since the official release of the S IV is in the couple of weeks, which means the official update will come next. I just can’t live with a phone heating up and draining my battery real quick.

But they release 4.1.2 for s advance,ace plus,mini2 and ace 2.. which are lower than our phone. I feel unrespected but we all know that after a period of time we must change our phones is order to have the newest softwere, even though i have my phone for about 10 months..

    once i have installed that rom following your steps mentioned above .. and it’s not the first time to flash a rom
    My phone became slower and lagging, and for some reason it started to freeze, I wiped data and its still the same ..
    I have tried to flash it again but its nothing new .. so I had to uninstall it and stick to the 4.1.2
    is there any advice you can give ?

    One or two minor glitches – when tapping “voice commands” in settings, settings app crashes. Also there is no developer options.. (can anyone confirm that they have this option in settings?) I did not wipe cache or factory reset when flashing, it still worked and preserved all my settings (glorious), so I’m aware that wiping may help with these issues.

    GS3 i9300, Rooted with chainfire superSU 1.25,and flashed new camera app with photosphere .. Works quite nice. Also flashed S Note zip which is cool. Overall the rom is slightly faster than 4.1.2 and besides new camera, lock screen widgets, and minor changes to the look, not much different to the previous JB. That’s my 2cents, any questions hit me up.

  90. viulian on said:

    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 ..
