[Upgrading, Modifying and Unlocking] shifattk:
Note: This is an old phone. It's no longer being supported by Samsung, and I see that nobody is selling this phone except for eBay or Amazon. I also have a new phone now and my Discover is simply sitting there for me to have fun with. I won't be actively developing for this phone. However, I will provide support with any issues you may encounter. This thread will be kept here for future reference if anyone needs help.

Update (2022):

​

I am no longer using Android. This is my last update here.​

Please thank Ivdoan he is the mastermind behind finding and implementing root for this phone.

Thanks to JohnnyGalto for giving us updated CWM, TWRP, and Partition Tables!

Issues and Bugs (Known Problems)

Okay, with deodexing - sometimes the SamsungIME.apk in the /system/app directory can be a pain to deal with! I put a warning in my deodex CWR script that tells about this issue. It does seem to correct itself overtime, so I am not too worried at the moment (but still very annoyed).

Also, it seems that many users have been experiencing strange battery problems (such as the phone suddenly losing half of its charge in 3 minutes). I hope it is an software issue (correctable), or just a battery issue (fixable), rather than a hardware issue (hard to fix).

Rooting, Custom Recovery, and Unbricking Guide (Everyone)

]If you want to root your phone then follow part A.

If you want to root your phone and add custom recovery then follow parts A and B.

If you have soft bricked your phone, then please complete all steps outlined below (if not already done yet).

The tutorial is done on a Windows computer and is meant for a Windows computer. Steps will vary slightly or tremendously if it is done on any other OS.

Part A - Rooting the SGH-S730m

1. Download and install UnlockRoot Free on your PC. YOU DO NOT HAVE TO INSTALL BLOATWARE!!! PLEASE READ SETUP INSTRUCTIONS CAREFULLY!!!

2. Download and Install Samsung USB Drivers. If it prompts you to reboot for any reason, then reboot your Computer.

3. After all of this is over, you have to prepare yourself for the hardest part of this whole process, and maybe the most complicated dilemma you will ever face in the entirety of your lives.

4. Turn on your phone if it isn't already. Wait for the phone to fully boot.

5. Plug your phone into the computer via USB.

6. Run UnlockRoot on your computer and click the "Root" Button (when it prompts you to install bloatware apps on your device, say no).

DO NOT UNPLUG YOUR PHONE UNTIL UnlockRoot SAYS IT IS OK TO DO SO!!!!

Congratulations, you have should now have a rooted SGH-730m in proximity to your hands! :fingers-crossed:

How to verify your 730M is rooted

If by any reason, you feel unsure as to if your phone is actually rooted or not:

Install a root checking app.

These apps will tell you if your phone has root access or not.

Try Root Checker from the Google Play Store.

Install a terminal emulation app.

In these apps, type the command "su" (without quotes). If you get "permission denied" you have not rooted your device. If it prompts you for root privileges (ie a popup appears) then your device is rooted!

Try Terminal Emulator from the Google Play Store.

If you are a n00b (like me occasionally), and you fail to understand why something works, or, the exact opposite: Don't worry! You probably thought the auxiliary headphone jack was the USB port, or, thought you should unplug your phone early, despite me warning you not to do that. That's okay, you can get it fixed.

Part B - Installing a Custom Recovery

YOU MUST ROOT YOUR PHONE BEFORE YOU DO THIS!!!!!

1. Download either the SGH_S730M.CWM_6.0.3.1.custom.recovery.tar.zip or the SGH_S730M.TWRP_2.5.0.0.custom.recovery.tar.zip file, and extract its contents to your desktop (if you donâ€™t know what a desktop is, then please leave. You will probably break your device).

2. Then, download the Odin Flashing Program attached to this post. Extract its contents to wherever you find necessary.

3. Right Click on Odin, and click â€œRun as Administratorâ€ (if available).

4. CLICK ON THE

PDA

BUTTON

5. When the file window appears, browse to the desktop directory (your desktop) and select either the

S730M-CWR.tar.md5

or the

S730M-TWRP.tar.md5

(depending on what version you downloaded).

6. Now shutdown your phone. Plug your phone into your computer. Boot into download mode by turning on the phone (release the power button as the phone vibrates) and holding the lower volume button and home key. Follow the instructions (press the upper volume button) to continue with download mode.

7. If your phone has been detected by Odin, the proceed.

8. Inside of Odin, press the

Start

button.

DO NOT DISCONNECT, UNPLUG, PLAY WITH ANY BUTTONS, OR CLICK ANYTHING ON EITHER THE PHONE OR COMPUTER UNTIL ODIN HAS FINISHED FLASHING CLOCKWORK RECOVERY ON YOUR PHONE.

8. To boot into clockwork recovery, hold down the upper volume and power key until the first vibration, then just hold the volume key.

That should be IT! :highfive:

Part C - Soft Brick Recovery (CWM Recovery Only!)

YOU MUST HAVE A MICRO SD CARD WITH AT LEAST 400 MB OF FREE STORAGE SPACE TO DO THIS!

build.prop restore script

You need busybox installed on your phone in order to use this script! If you dont have busybox, it wont work.

If you messed up your build.prop file (If you did, then you will know that you did), then you can use this script to restore you build.prop file to the original stock format.

1. Download the build.prop restore script, to your device (preferably a computer).

2. Place the zip file to the root (/) directory of your micro SD Card.

3. Remove the SD card from the computer, and turn off the SGH-S730M.

4. Remove the back plating from the phone, and insert the micro SD card into the phone. It should be named SGH-S730M CWR stock build.prop.

5. After putting the phone back together, boot into recovery by holding down the upper volume and power key until the first vibration, then just hold the volume key.

6. Using the volume buttons as scrolling keys, scroll down using the lower volume until you see install zip from sdcard as highlighted text. Using the power key as the enter button, click the power button.

7. Then, also using the volume keys, scroll down to the choose zip from sdcard option, and click the power button.

8. If you placed the zip file exactly where I told you to: you should see SGH-S730M CWR stock build.prop as an item. Scroll down to the file and click the power button. Then, when it prompts you to "Confirm Install", scroll down to "Yes - install".

9. Press the power button.

WAIT FOR THE PHONE TO BE 100% DONE EXECUTING THE SCRIP! YOU COULD MESS UP THE PHONE. DO NOT TURN OFF THE PHONE.

Full Restore (If all else fails)

To reduce confusion, please remove any backups that you may already have (which would be funny, you wouldnt have to do this anyways).

1. Download the rooted stock CWM Recovery Image (.zip) from here, to your device (preferably a computer). http://xdaforums.com/showthread.php?t=2677332

2. Extract

ALL

of the contents of the zip file to the root (/) directory of your micro SD Card. The folder should be named "clockworkrecovery".

3. Remove the SD card from the computer, and turn off the SGH-S730m.

4. Remove the back plating from the phone, and insert the micro SD card into the phone.

5. After putting the phone back together, boot into recovery by holding down the upper volume and power key until the first vibration, then just hold the volume key.

6. Using the volume buttons as scrolling keys, scroll down using the lower volume until you see backup and restore as highlighted text. Using the power key as the enter button, hit the power button.

7. Then, also using the volume keys, scroll down to the restore option, and click the power button.

8. If you extracted the zip file the exact way I told you to: you should see a menu option. If you didn't do what I told you to, you may see "No files found". If it says "cant mound /sd" (or something similar), you probably have a bad SD Card, or, forgot to put it in correctly.

9. Press the power button.

WAIT FOR THE PHONE TO BE 100% DONE RESTORING YOUR BACKUP TO THE PHONE! YOU COULD HARD BRICK THE PHONE (BECAUSE CWM RECOVERY WRITES TO THE BOOTLOADER). DO NOT TURN OFF THE PHONE. THE PHONE IS NOT FROZEN IF IT WONT RESPOND FOR A WHILE.

10. If you did this correctly, you should have a rooted, and restored SGH-S730m!

Part E - Removing that annoying triangle from the boot sequence

Use the triangleaway script in the attatchments. (triangleaway.zip)

It resets flash counter and resets binary status to official.

Might have to do a factory reset to return current status to official.

Boot your phone into recovery mode

Extract triangleaway.sh from the zip file.

Open up ADB Shell

push triangleaway.sh /tmp

chmod 755 triangleaway.sh

execute triangleaway.sh

Reboot Phone.

Overclocking and Modding (DEVELOPERS ONLY)

SYSTEM MODS

If you don't know what you are doing, then, please don't read any further. its for your own good :)

The CSC directory can be deleted (and the files in the main /system directory that are associated with it). It does not affect the phone at all. Also, If you go to /system/etc/feature_default.xml you can change the phones features. So far, I have done many tweaks to the Messaging, Phone, Settings, People (Contacts) and Lock screen of the phone! If you are a developer (or tweaker like me), you should be able to enable/disable whatever you like using the feature_default.xml.

Overclocking

FitAmp has made a overclocking script for 1GHz (1000MHz). There is quite a noticeable difference in response, but, the phone still tends to lag a bit. File is attatched to the thread (

S730M-OC-1000MHz.zip

)
