[Galaxy S III General] IparryU:
How-to: Root, Unlock, Enable Osaifu Keitai/Felica, CWM, cook & flash ROM on SC-03E

THIS HAS BEEN UPDATED ON 2015 FEBRUARY 04​

I no longer will be testing or using the SC03E. I am also going to unsubscribe from this thread as I have many other threads to look after and I prefer to forget this phone... GGPO

Below is the link to [MENTION=701636]zozew[/MENTION]'s FTP server with all the files you need.

http://www.anniblue.com/xda/xda_sc-03e/XDA/SC-03E

Note that you can use i9305 versions of most ROMs, but beware that it may not work perfectly and you need to flash CherryS after you flash your ROM of choice. For newer versions that are not uploaded, Google is your friend!

(hint: ROMname+i9305+XDA will get good results in Google!)

Download Odin v3.07, launch the program, then restart your phone and go into download mode.

IF YOU NEED TO UNLOCK YOUR PHONE, FOLLOW THIS GUIDE BEFORE FLASHING CWM!

Prerequisites:

Windows PC running Odin3 in an administrator account (tested with Odin3 v3.07)

USB cable to connect phone to PC (preferably original cable for reliability)

Internet access to download firmware image(s)

Google account to access Play Store

The following list outlines the required steps in order to successfully unlock your SC-03E:

If you have data on the phone, which is of any importance to you, then I highly recommend that you make appropriate backups first

If present, remove the SIM card and SD card (there's no need to have a Docomo SIM card for this procedure to work)

Download this stock firmware image, which is based on MB1 and includes the appropriate modem component to assist in wiping the NV stored network locking data structures. In addition, this firmware image is root-ready; meaning that you can toggle root mode by pressing VolumeUp/VolumeDown/Power button combination briefly to switch modes.

Initiate Odin Download mode on the SC-03E (Turn the phone off, then simultaneously press VolumeDown/Home/Power buttons until the Download Mode splash screen appears and requires you to press VolumeUp to continue or VolumeDown to cancel if you find yourself suddenly struck by an overwhelming feeling of stage-fright)

Unpack the SC03EOMAMB1_LK5MDM.tar.md5 firmware image from the above-mentioned/downloaded zip archive and flash the file with Odin3 (specify the image file in Odin's PDA section)

As soon as Odin completes the flashing process, it will instruct the phone to reset; be patient while the phone starts up, because it will require more time to set-up and configure itself after a factory reset.

If you have reached this step, then we're assuming the phone has booted successfully and you are presented with the configuration wizard. You need to at least enter your Google account credentials in order to access the Play Store.

Install the (free) ServiceMode Shortcut app (author: KABASOFT) from the Play Store.

Another (paid) option is the ShowServiceMode For Galaxy LTE app (author: Jaken's Laboratory).

Start the service mode app and tap the ServiceMode option, which will in turn fire up the ServiceMode main menu

Select [1]UMTS->[1]DEBUG SCREEN->[8]PHONE CONTROL->[6]NETWORK LOCK->[3]PERSO SHA256 OFF

Now use the phone's android menu soft button to select Back in the pop-up menu to return to the NETWORK LOCK menu

Tap [4]NW LOCK NV DATA INITIALLIZ and wait for about a minute before returning to the NETWORK LOCK menu; when you tap this option again, it should state PERSO_NV_INIT is SUCCESSFUL

You may now power off the phone to insert a SIM card from your favorite telcom operator and restart the phone

From this point onward, it is possible to flash any other firmware image without affecting the unlocked state

Enjoy!

Flash Stock Firmware (courtesy [MENTION=4524799]davidcsv[/MENTION])

-Just open Odin, do not change anything (auto reboot and f. reset time should be the only things checked), and click the button that says PDA... and select the above file (extract it first).

-This is also the same firmware that is in [MENTION=4524799]davidcsv[/MENTION]'s unlock guide, just hosted on AnniBlue.

Re-Enable Osaifu Keitai/Felica Part 1 (NOT NECESSARY IF YOU DONT USE OSAIFU KEITAI OR IF YOU LIVE OUTSIDE OF JAPAN)

Thanks to SlateBlue and their easy to understand instructions!

https://sites.google.com/site/rootsc03e/felica

After you complete the initial set up, Enable installing apps from unknown sources and enable USB debugging in the developer options.

Now download and install GNT2/S3α eXtreme Tuner

Before launching it, you will need to press VolUp+VolDown+PowerButton to toggle root, now you should see the Samsung logo twist and it will look like the phone restarted.

Now launch it, and choose "Felica Control"

Now choose Felica Device Keys. When I first did this it asked something and I accidentally clicked something.... BUT

Press it again (if the same thing happened to you) and choose the option on the very right.

The process is not complete yet... and you will need finish up the process later... just read the guide.

Flash CWM:

Flash sc03e-KK-KBC-CWM-v6.0.4.7_r1-recovery.tar in Odin then restart your phone and get into CWM (hold home+volume up+power button). Upon exiting CWM you will be asked to fix your root binaries... say yes!

Thank you Masashi Seino!

Cook your ROM (ONLY For 4.2 and 4.3! For 4.4 ROMs):

make_japanized_ROM_SC03E_IparryU.7z

OK, I edited the Japanize ROM cooker so it has four options. Please note that the 4.4 options are obsolete a we can flash CherryS. Read on below for that info.

Convert ROMs for 4.2

Convert ROMs for 4.3

Convert ROMs for 4.4 *this is under development, NOT WORKING

Convert ROMs for 4.4 with Boeffla boot.img *this is under development, NOT WORKING

Make sure you:

Have the cooker file path with NO SPACES

-i.e. - C:\cook\ (extract here)

The ROM name has NO SPACES (e.g. NameOfTheROM.zip)

You have JDK 6 installed! NOT JDK 7!

Copy the ROM in the same folder as the file named 'make_japanized_ROM_SC03E.bat'

Now drag and drop the ROM you want cooked on to 'make_japanized_ROM_SC03E.bat' and wait for it to complete

Reboot into CWM (hold volume up + power button + home) and install the ROM, Make sure you have all the files on your SD card also.

Wipe data/factory reset & wipe cache partition & wipe dalvik cache (under 'advanced')

Flash your new ROM

Flash CherryS if you want Boeffla kernel and/or if it is NOT a SC-03E ROM. Make sure you flash the proper CherryS kernel (Samsung/stock ROM, AOSP, MIUI)

Flash the proper GAPPs for the ROM you are using. Refer to their designated threads for that info.

Re-Enable Osaifu Keitai/Felica Part 2 (NOT NECESSARY IF YOU DONT USE OSAIFU KEITAI OR IF YOU LIVE OUTSIDE OF JAPAN)

-Start GNT2/S3a ExtremeTuner and choose "Felica Control"

-Now choose "Unlock Felica Device"... but the text just stayed up there for me... So i just hit the back button and it worked!

-In the Japanese guide it said you need to reboot, but I didn't need to.

Congrats, you are all done! w00t!!!

Resetting your custom binary counter​

Thanks [MENTION=301316]majin[/MENTION] and his guide

Wipe cache partition, data/factory reset and wipe dalvik cache in CWM

Install, launch and apply Triangle Away

Let the phone reboot, BUT DON'T LET the OS be loaded! PUT IT IN DOWNLOAD MODE (volume down + home + power) BEFORE THE SAMSUNG LOGO APPEARS!

Flash stock ROM using Odin

IMPORTANT Factory reset and wipe cache from stock recovery mode (volume up + home + power)

ROMs that I use < prefer in the following order​

JCOM CM 10.x - Works great and dosnt have that stupid anime chick that Masashi Seino included in it. I didn't even want to show people my boot screen cause of that silly little ****. But this ROM works well and is the most stable and less buggy ROM for this device.

Slimsaber i9305 - This is a well developed ROM and has all the features you can ask for. This ROM has the ****ed up mic so people cant hear you when using Line, Skype, etc. Basic phone works for some reason.

CM11 i9305 nightly - Works great, same sound issues as Slimsaber

Mokee SC03E - Too much chinese apps included and has the sound bug...

AOSB i9305 - Has so many features, but lack of updates and bugs here and there.

PACman/Liquidsmooth/Omni i9305 - Great ROM, but still buggy for the SC03E.

To sum it up, screw this phone and I cant wait for the Nexus 6 to come out so I can stop stressing over it.
