Hello, I'm wondering if there is a guide or any info at all about rooting the KDDI's SGS3 LTE. I saw a bunch of thread for the NTT DoCoMo version but none about the KDDI version. No idea if they use the same hardware or not.
Root success by flashing CWM recovery and sgs3_rooting_supersu_v3.zip. Those tools are specified for Galaxy S3 NTT Docomo (SC-06D) but they also worked for Galaxy S3 Progre from AU KDDI (SCL21).
Just wondering how to unlock this SCL21, if anybody knows, please share.

I am also trying to find out a way to root my SCL21 but am having no luck. I have tried many of the "Universal 4.0.4 rooting methods" but have had no luck. Brong, would you mind sharing exactly what you did? The threads here http://forum.xda-developers.com/showthread.php?t=1999024 and here http://forum.xda-developers.com/showthread.php?t=1996940&page=2 warn about using the docomo method because it bricks the phone. Nothing seems to work with our model. Any help would be appriciated. Thanks.

Hi,
First step is flash the CWM recovery via Odin. You can download CWM recovery from here:
https://docs.google.com/folder/d/0B...ZhbUE/edit?docId=0B98X7HyfoaGaNzNvR052dUp0Wmc
Choose this file: SC06D-JB-KBC-CWM-V6.0.1.2_r10-recovery-odin.tar.md5
Flash that file in Odin, choose the PDA in Odin.
I assume you already know how to flash via Odin, if you dont know just ask me again or try to browse other thread.
Step two is run the CWM recovery. Also, I assume you already know to get into recovery mode. Make backup first in recovery mode, you need to insert external SD card and save the backup in the card.
Step three, download this file sgs3_rooting_supersu_v3.zip from here:
https://docs.google.com/folder/d/0B...ZhbUE/edit?docId=0B98X7HyfoaGaR21wdXZweDdYSXM and save it to the external SD card that you used before.
Step four, run the recovery mode again and choose install from SD card, then choose external sd card and choose the file you donwloaded (sgs3_rooting_supersu_v3.zip). After completing all, reboot your phone and you will see the Super User app. Make sure you download root checker in Play store so you can check whether the phone are rooted or not.
Note: If you run the recovery, the screen will reverse. Dont worry, it works eventhough the screen reverses.
Thats all. I am looking the way to unlock this phone, *#197328640# doesnt work. If you have a clue, please let me know.

I see a Vietnam website with video on youtube. It shows that this phone has been unlocked.
http://choimobile.vn/threads/unlock-samsung-s3-scl21-au-kddi-nhat-ban.2699/
Any idea how to SIM unlock this phone?, really appreciate any help.
Thanks.
Updated:
I found a new thing regarding this phone. This phone doesn't support non LTE sim card, even you have micro sim (3G) card from AU KDDI. I am trying to find other LTE sim card from other carrier in order to check whether this phone works on that sim or not.
May be somebody can explain why this phone doesn't support non LTE sim. In case of Galaxy s3 LTE from NTT Docomo, it works when I used 3G sim (FOMA). I cut the 3G sim to fit the micro slot.
unlock for this phone
well, my purpose is/was to unlock this phone so I followed the samsung galaxy s3/note unlock method from here: http://forum.xda-developers.com/showthread.php?t=2014982
(I have/had this S3 Progre SCL21, the same phone in this thread)
I can access all the menu and procedure from that thread below, despite this phone being stock Android 4.04!
----------------
"Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone..."
---------------
I put 3G/2G sim card and the phone shows no service. I even put CDMA network sim, no luck. I don't know if this phone is unlocked. I'm wondering if this phone works only with LTE/4g sim. Right now, there's no 4G/LTE in my region
I assume the phone must support all other bands, if properly unlocked.
Now, I'm wandering through the threads and googling.
So far, I'm looking for Jelly Bean 4.1.1 for this phone, which doesn't seem to be available anywhere, even on samfirmware, only stock firmware
Root/flash CWM recovery and try some other unlock method from out there, (after making a backup Stock ROM and sensitive IMEI/NV data of course)
Please keep everyone updated and keep the spirit alive

Actually this phone, SCL21 can be used with LTE sim card only. I already tried to use non LTE sim card from KDDI AU with no luck.
What I am thinking is actually this phone maybe unlock-able by using the procedure as you mentioned (NW Lock NV Data INITIALLIZ). Since the phone can only be used with LTE sim card, we need to try LTE sim card from other carrier in order to test.
The problem is I dont have other carrier LTE sim card right now, if you have you can try it.
Update: Also I am wondering how to make this phone works with not only LTE/4G but also with 3G/CDMA. I changed the band to automatic, but there is no luck. I think this phone is locked to be used only with LTE/4G sim card. So, if somebody knows how to deal with this matter (make the phone not only accepts LTE/4G sim card, but also 3G/CDMA sim card) please share with us here.

Hi everyone ^_^
I just got the SCL21 about two weeks ago. I think it's really strange that even on the Japanese forums, there is very little info on rooting this model. From everything I've found, some Japanese sites also both say it's OKAY to root using the Docomo SC-06D recovery and Superuser zip while others say that it's NOT safe to use that same method and it will result in a bricked phone. Really odd, conflicting messages I think.
What is even more strange is the apparent issue with the screen "reversing"? One of the Japanese sites literally said the screen becomes "upside down" after flashing the SC-06D recovery.
Brong, since you got the root to work successfully , could you please elaborate on the "reversing" of the screen? Is the image upside down and only during the recovery mode? Also, do you know if the root caused you to lose the "osaifu Keitai" touch feature?
Thanks a lot to Brong and everyone else helping out with this model phone!!

Status of SIM access
Hi,
I tested both a 3G micro SIM and a 4G LTE nano SIM from Softbank in this phone and neither card is recognized. The phone acts as though no SIM is inserted at all. (Complete with the "no smoking" symbol (circle with diagonal line through it) instead of a signal meter. I have confirmed that this phone is indeed sold already SIM unlocked from the factory as the MSL is 000000 just like the Verizon Galaxy S III which is also sold without a SIM lock. Additionally, KDDI lists the SCL21 and all other LTE phones they are selling since the debut last winter as being SIM unlocked devices.
According to some Japanese forums, they are suspecting that this phone has some type of hardware lock (hard locked?)... I contacted the only known person who was successful at using a 3rd party SIM on the Vietnamese Viettel GSM network as in a YouTube video. He wouldn't give me any details except that he must have the phone physically in his shop to modify it and it can't be done remotely. This individual also has screenshots showing the stock ROM version running in Vietnamese which makes me believe that he flashed something to the stock ROM to gain SIM detection of 3rd party cards.. Anyone have any ideas about such a hardware locking mechanism?

my phone need to unlock, please help
He's referring to the service mode. In that case, here are the steps to perform an unlock using the service mode (tested to work ONLY on the docomo models SC-06D and SC-03E; NO GUARANTEE IT WILL WORK ON THE SCL21):
1. Enter service mode by dialing the code in the dialer.
2. Press "UMTS".
3. Press "Debug Screen".
4. Press "Phone Control".
5. Press "Network Lock".
6. Press "Perso SHA256 Off".
7. Menu->Back (if the menu button turns up nothing, then just push "back") then wait 30 seconds.
8. Press "NW Lock NV Data Initallliz" then wait around one minute.
9. Reboot the phone and it SHOULD be unlocked. Works great on the SC-06D and SC-03E, no guarantees with the SCL21. And with the SC-03E newer basebands either hid it away or blocked it out so an older one needs to be flashed in before it will show up for unlocking.
Anyone looking to get one should only do so when they've got a trip to Vietnam in their future (to go get it done in a shop there; they still seem to be the only country with shops doing it) or be using au in Japan.
s3 scl21
that`s the first instruction i found when i was browsing the net and tried it but unfortunately it didnt work...... there are still settings in the service menu and all you have to do is click everything that has something to do with the wcdma to gsm..gsm to wcdma or g to wcdma something like that. There`s also a setting that tells somethin like resetting cant remember the exact word and you have to wait for 90 or 60 secs.and restart the phone .and then go back to changing gsm to wcdma .,there`s a setting also that you have to change the frequency .cant remember the step by step guide but because of my eagerness to use the phone i clicked everthing in the service menu and searched every command listed in there.(dont worry it will not brick your phone).After doing all that... this is what happened .. i thought i failed again because the no smoking sign was still there ...so what i did was i clicked the settings and i was so surprised that the menu for mobile network comes out meaning to say that i was able to unlock the settings on the network ..im telling you guys this is what vietnamese unlockers have been doing to unlock this phone that is why they need the phone physically....thats all thanks
And it never prompted for a SIM unlock PIN again? Somebody really needs to go through this carefully and document it; an SCL21 is only 24-25k yen in Japan; I've heard of people paying more to fix broken screens on their international/American S3s.
scl21
as far as i know this particular phone model (s3 scl21) from AU KDDI is not sim locked . The first time i inserted the 3g simcard, it didnt ask for a pin code or anything ...what i could see was the no smoking sign and the simcard icon is there in the apps menu.
it's diffcult to unlock... i can't use in my country... please help

Hi,
I am on t-mobile network, my problem is that i don't seem to get EE network on my S3, it will change the between t-mobile n orange not ee. When I insert sim into iPhone then I will get EE network. I have tried unrooted n rooted but no EE.
Now when am on t-mobile network my Internet is really good but as soon it's moves to orange network then Internet is really really slow, I mean 34kbps.
I have contacted t-mobile n tried everything but no luck.
Is this something to do with S3?? Anything I can do? Any advice appreciated

I'm on t mobile/Orange through t mobile, Orange signal is rubbish, never gets h or h+, but as I'm on t mob, it reverts to them by preference I think, only switching to Orange when it looses signal.
I used to be on Orange, and then I always had to go into settings and select network (choice of EE or EE!) So it's a bit hit and miss.
I also sometimes get it showing as t mob in notification draw, and sometimes EE, all very confusing.
EE sucks!!! Nothing wrong with your phone.... I've got Orange and 3UK. With the second one I'm more than happy. Download up to 26Mbps!
I never get EE on my S3....do you ever get EE?
Also is there an easier way to swap networks?

Are y you with orange or t mobile?
I'm with Orange and I've never had a problem in having H+ my carrier signal mostly shows EE.But isn't that all it is? a re branded carrier signal from orange and T-Mobile?
It's weird cos I get EE network when I put sim into iPhone
T mobile
Why is it that I don't get EE anywhere? Also I do get H+ but Internet is awful... Am thinking it's something to do with my S3 or firmware, radio etc

Are you on latest mb5? Are you locked and branded?
Also don't about it displaying ee or not, the other thing you could try is go to tmob website and get the apn settings sent to your phone, they may need updating
Sorry don't know about mb5? How do I find out? Plz
Unlocked n unbranded
I have done t-mobile website but apn setting does NOT come over to my phone for some strange reason... I have entered ee apn setting manually but still no EE network. I am not fussed what network it is on as long as I can get Internet!
Currently limited Internet on orange n full on t-mobile.
Download mb5 here. http://live.samsung-updates.com/details/7693/Galaxy_S_3_International/GT-I9300/BTU/I9300XXEMB5.html
Flash with Odin, this is the latest UK unbranded
Once you've flashed the MB5 modem & matching RIL, go to settings, more settings, mobile networks, network operators and make sure 'select automatically' is chosen.
Then go back to mobile networks, access point names and delete all the APNs listed. Then create a new APN but only complete these fields; name: Everywhere APN: Everywhere
Reboot the phone and you should have a better experience.
You can also find a CWM flashable MB5 modem & RIL in kamalmawa's thread:

Have you contacted to your operator it could be helpfull also
Yes.... As far as they concerned everything is fine.
Also bear in mind that the network is undergoing a lot of engineering at the moment due to the marrying of the two networks and the LTE network introduction, but for me Orange has always been rubbish so I just select t mob and live with the pain of selecting the network occasionally if it gets hung on Orange

Just flash the zip in recovery, the RIL is included and it will even backup your existing modem. No need to play with root or the ROM, as long as your current ROM is rooted.

You may need to flash a Three modem
Read this: [REF] Galaxy S3 Modem / Radio Collection (I9300 & I9300T ONLY) CWM & Odin Flashable
To flash a new modem:
1. Download an official rom from http://www.sammobile.com/firmwares/ and extract the zip to md5 then extract the md5
2. In Odin, select “CP”(previously “Phone”) and fetch the modem.bin file
3. Only thing checked should be “Auto Reboot”
4. Put the phone in download mode, plug in USB, then in Odin hit Start
Hello Guys,
I have a Tmobile s6 edge. I have unlocked it to use in Brazil. Everything was working fine but I had a trouble with root and ended up soft bricking (not passing the Tmobile logo screen)
I managed to reinstall Tmobile stock rom and make it work again. All was fine but this afternoon the phone decided not to register on the network anymore. Weird thing is that I still have connectivity over 4g. I tried a Tmobile Sim card and get the same problem.
Any suggestions? Should I root it and flash a custom rom? Different radio? Everything else is working fine.
Thanks!
Turned out that the imei was blocked. I managed to change it through a company in the US. Now it's back to normal.
Go to settings > mobile networks > network operators and select search automatically.
If this doesn't helps then tap on search networks and select manually,this worked for me.
