It's great to hear that you have rooted successfully the SGH-S730M. For me, I have bricked mine. It is appreciated if your can share the boot, recovery and partition image of your phone to us so that we can repair the brick.

It is fairly easy to backup your ROM:

1. Download and install ROM Manager from Google Play (the free version works great).

2. Run the program and click on "Backup Current ROM" and click OK - remember to have your external Sdcard inserted to have more space for the backup. By default the file name of the backup which will be created is your current date.

3. Look for the folder "clockworkmod" in the sdcard, in there you will find the folder backup, then in that folder you see a sub-folder with all backup files.

For me, I need the file "recovery.img" so that I can restore my blicked recovery of my Galaxy Discover.

Looking forward to hear from you the soonest.

Pls mail me the file to lvdoan@gmail.com or give the link so that I can download

Thank you in advance.

[Upgrading, Modifying and Unlocking] punk_zappa:
Sorry, folks. Been working on it for almost 6 hours with both romdump and ROM Manager. ROM manager cannot backup because "phone is unsupported". With romdump I am having "segmentation fault".

If you guys have anymore ideas please throw them in.

BTW, that unlock-root worked and it is very simple.
[Upgrading, Modifying and Unlocking] lvdoan:
If the above method does not work, you can follow the instruction on the below link:

"xxx.addictivetips.com/mobile/how-to-backup-your-android-phones-boot-recovery-and-system-partition-images/" (replace xxx by www)

However, for this method, I recommend you to download the latest version of the romdump "romdump_v82b.zip" on the link: "android.podtwo.com/romdump/" because the version 72 does not seem to work.

---------- Post added at 12:38 PM ---------- Previous post was at 12:24 PM ----------

When using the romdump, please download the version 82b.

I did rooted my SGH-S730M. However, I earlier flashed the wrong recovery image and I no longer can boot into recovery. I still can make phone calls. I dumped the phone ROM using the method above with latest romdump v82b, the result ok but I could not see the exported "recovery.img". I thought that because my phone's recovery has been broken that the romdump could not export the file "recovery.img".

Can you just try with the latest version of the romdump please and let me know the result.

Thanks
[Upgrading, Modifying and Unlocking] punk_zappa:
I am using 82b, but file is "romdump" instead of "install". I have both files in the phones internal "sdcard" and the commands,

adb push install /data/local/

adb shell chmod 04755 /data/local/install

adb shell /data/local/install

(I replaced install with romdump) it doesn't seem to work, coming back as cannot stat 'install' or 'romdump'; no file or directory.

If you guys can instruct me on how to do this properly using ADB.
[Upgrading, Modifying and Unlocking] punk_zappa:
"Segmentation fault" is persistent. I've been trying to read up all day and no joy.

If someone can make us CWM for this phone.
[Upgrading, Modifying and Unlocking] meldo:
I could suggest you install supersu from market and update su binaries, then look for adbd insecure.

With the link I sent in pm your should be on track.

Install busybox installer from market and reinstall smart too
[Upgrading, Modifying and Unlocking] lvdoan:
1. Ensure you have all necessary file to run ADB and place them in drive C: of your PC

2. Copy file "romdump" v82b into the folder "data/local" of your phone using "Root Explorer" programme

3. Do as what you can see in the attached picture.

4. Look for folder "romdump" in your sdcard, everything is there.

I am sure you can do it.
[Upgrading, Modifying and Unlocking] lvdoan:
Donot use "install", instead copy "romdump" to folder "data/local" and run "su" then "data/local/romdump"
[Upgrading, Modifying and Unlocking] punk_zappa:
I don't need the others as per instruction?

will try later.
[Upgrading, Modifying and Unlocking] lvdoan:
Forget "install", just copy " romdump" into folder "data/local/" of your phone and follow exactly the steps in my attached picture above.

The command "chmod" is meant to change the properties of "romdump" to give it the right to excecute. If you cannot run romdump, you can run, in the first place, the command chmod 04755 /data/local/romdump then the command romdump itself.

The important thing is that in order to get full access to the phone system, you must run "su" command first then the command "data/local/romdump". When you execute su command and if successful you can see at the command prompt the symbol "$" turns into"#" (su and Super User are both installed in the phone system when you successfully rooted your phone). Normally the "su" is located in the folder "system/bin" or "xbin".

---------

The other way round is to install "Terminal Emulator" from the Google Play then launch Terminal Emulator and enter series of commands on the phone itself as you would do on the PC (see my attached picture in my earlier reply):

1. You have to copy "romdump" v82b into folder "data/local/"

2 run "su" (no need to specify path) - symbol "$" turns into"#" (if you can see "#" at the command prompt before runing su, no need to run su)

3. run "chmod 04755 data/local/romdump" (optional if romdump has no execute right yet)

4. run "data/local/romdump" and wait for it to complete.

------------

If you do the way you have previously done from drive C: of your PC, just do the followings:

1. adb shell

2. push romdump data/local/ (make sure first you have to copy "romdump" to C: drive where you have all your ADB files) - this command will copy "romdump" to "data/local" folder.

3. chmod 04755 /data/local/romdump - this command to give romdump execute right.

4. data/local/romdump
[Upgrading, Modifying and Unlocking] punk_zappa:
Did as you instructed, romdump is in data/local but this is what I got;
[Upgrading, Modifying and Unlocking] lvdoan:
Have you turn on read/write for the sdcard?

If not, use Root Explorer and browse to sdcard and click on "mount r/w"

or you can manually create empty folder "romdump" in the folder "sdcard"

---------- Post added at 11:31 AM ---------- Previous post was at 11:26 AM ----------

You are near success.

Just do this again:

1. adb shell

2. push romdump data/local/ (make sure first you have to copy "romdump" to C: drive where you have all your ADB files) - this command will copy "romdump" to "data/local" folder.

3. chmod 04755 /data/local/romdump - this command to give romdump execute right.

4. data/local/romdump
[Upgrading, Modifying and Unlocking] punk_zappa:
I think we are getting somewhere;

I only see config.gz, sysem.info.gz, system.tar...and i cannot see them in Windows (only in root browser).

Keep the instructions coming.

EDIT: As soon as I closed ADB files became visible. Let me know if you guys need them and I will upload it.
[Upgrading, Modifying and Unlocking] lvdoan:
In the phone, use the Root Explorer (or any phone browser) and navigate to sdcard, Can you see the folder "romdump" in there?

In that folder, everything is exported.

---------- Post added at 12:45 PM ---------- Previous post was at 12:40 PM ----------

That's awsome !

At the moment, I need the "recovery.img" file to repair my phone's recovery.

Thanks a lot.

---------- Post added at 01:09 PM ---------- Previous post was at 12:45 PM ----------

Desperately waiting for the "recovery.img" file. Is it in the .tar file or just .img ? If in the .tar file, it will be easier for me to use Odin to flash back to the phone.

Can you send it to me now.

root and unlock Samsung SGH-s730

The two methods suggested in this forum 1) the Polaroid AIO and 2) the Unlock Root , which one is better to root and unlock the Samsung SGH-s730. Would appreciate a walk through of using the unlock root.com software and whether I need to use the Pro version or the free version would do to root the Samsang Discover. Thanks
[Upgrading, Modifying and Unlocking] lvdoan:
Please use the latest Unlock Root pro version. It works like charm.

I just recently used Unlock Root to root my Net10 Galaxy discover preparatory to using directory bind in order to install things to the SD card once I get a good high capacity high speed microsd. I immediately discovered that display auto-rotation was completely disabled. I can use a rotation app to manually rotate, but no auto-rotation setting now works.

Anyone have any ideas what to do to fix this? I'm not rooting my fiancee's phone of the same make and model until I know that will work the same as before I did it.
[Upgrading, Modifying and Unlocking] lvdoan:
unroot and root again
[Upgrading, Modifying and Unlocking] CaptJosh:
Already did that. Same result. However, later in the day, the battery popped out, and when I got the phone back together and powered on, it was working again where a soft shutdown hadn't worked. Very strange.
[Upgrading, Modifying and Unlocking] D'Anklaud:
Just wanna say thank you to all , i will be buying this phone in 6-7 weeks(april 5th gst return), only because you have found root for it (again , thank you), so i looked and found kernel source for it as well(go to http://opensource.samsung.com/reception.do , then type in sgh-s730m), so ill just need to find the right compiler for it and fun shall begin
[Upgrading, Modifying and Unlocking] CaptJosh:
Too bad the source there is only for the version of the OS that's actually on the phone. Why couldn't they have sources for an upgraded version of the OS?
[Upgrading, Modifying and Unlocking] lvdoan:
Hope you can get things compiled from that open-source code and share among Galaxy Discover users.

For concerted efforts, pls contact those guys "meldo", "camvar97" or "punk_zappa", they have quite a bit experience on this phone and helped me alot so far. Thanks guys.
[Upgrading, Modifying and Unlocking] D'Anklaud:
LOL.... so i compiled the kernel today , but no go ( my other kernel - samsung galaxy tab 2 7" - still comes out fine), turns out they released faulty mismatched source , but im gonna debug it ( and bug them )till they release normal source , i like this phone (and i dont even have one yet , LOL )

Root method

Tried SuperOneClick, froze up. The UnlockerRoot method did work for me after some trail and error.

Steps that worked for me:

Downloaded and installed Android SDK

Downloaded and installed Keis http://www.samsung.com/ca/support/usefulsoftware/KIES/JSP

Downloaded and installed UnlockRoot Free (Direct download link: http://downloadcdn.betterinstaller.com/installers/9/9/UnlockRoot_downloader_by_UnlockRoot.exe

Ran it, didn't install the "power saver" app (BatteryDefender is better IMO)

Searched on phone for SuperUser.apk but apparently it has "SuperSU" (Never heard of it, it needed to be updated)

I recently won a SGH-s730m from one of those "stack'em" machines for about $5 (not a bad deal if you ask me :) ). The only problem is that the phone's carrier wont unlock it unless I use their service for three months.

I want to use MY SIM card in my $5 brand new Samsung discover.

Yes, I want to do it the hard way.

Yes, I am very literate!

Can someone please post a root thread for this phone, or, post a step by step instruction guide on how to root this phone. (And maybe even root carrier unlock, or, link to the appropriate thread would be awesome).
