Info star code not working anymore - T-Mobile Samsung Galaxy S 5

Hello all
I used to use the code *#*#4636#*#* to force the phone into LTE only mode and that allowed me to also change the bands the phone used.
After the most recent update (stock rooted Knox not tripped) that seems to no longer function.
Anyone else having the same problem? Or know how I can enable access to that again?
Thank you.

Never mind figured it out

[REQ/INFO] KDDI Au Samsung Galaxy S3 LTE [Model: SCL21]

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

[GUIDE]Maybe the EASIEST WAY to enable hidden menu in i545

Just dig out the easiest way to enable those special mode on i545
ROOT REQUIRED
SAMMY ROM REQUIRED (wont work on AOSP/CM roms, not sure about custom sammy roms)
Use ROOT Explorer (or other root app of your fav)
look for
Code:
system/csc/sales_code.dat
Original File content is
Code:
VZW
edit it to
Code:
SPR
PROFIT!
Code:
##DIAG#,
*#7284#,
*#9090#,
*#06#
find more?! Please REPLY
Behind the scene:
By editing the CSC file, trigger this device to act like a Sprint S4, as Verizon hide those features for evil.
It could enable more hidden feature that is hide by Verizon, maybe give a try?
In Settings, you can Disable LTE now, probably more Sprint features on Verizon maybe?! for your discovery!
Regular Disclaim Apply
It works for my i545 on Factory Loaded ROM, maybe works for you, maybe not
and I dont responsible for your bricked device or what so ever
Nandroid Backup is highly suggested including EFS!!!

You have to modify the file, erase the VZW (Verizon Wireless) and replaced it with SPR (Sprint) or any other regional code, then reboot and you're done.

LG Leon not getting 3G/4G in Spain

Hi,
I have just return from US and I got a LG Leon from MetroPCS to sty connected while there. Now that I am back I unlocked the phone via unlock app. My surprise came when I put me Spanish SIM card (Jazztel) and the phone only gets 2g connection. I have been searching the net and I found some threads on the topic but I can not make any of them work on my phone. First I tried changing the radio to Europe mode through *#*#4636#*#*, and I enter the test page but when I click the phone info button I get a message that states that I can not run that application on this device. I thought it was because I wasn't root so I rooted it. But before I could root I had to downgrade by flashing an older firmware. No way, I get the same message. I tried the hidden menu to see if I could find an entry to change the radio mode, or any type of LTE configuration. Hidden menu on my phone though 277634#*#. I also tried the anycut option, but I do not get any facility called LTE configuration or similar.
I am desperate and I do not know how to proceed. Any help is welcome
Thanks in advance

Locked myself out of CSC changing screen [Help]

Obligatory - This is my first post here, please go easy on me. If this is the wrong section please point me where I need to go.
Okay, I have been having issues getting IMS registration (for att) on my N20U (unbranded) Snapdragon. This is an issue because I don't receive most calls without VoLTE, and the service I am using is actually FirstNet. (An at&t service that provides priority cell tower access for first responders.) Who is also dropping legacy 3G and analogue calling at the end of the year.
The FN sim I was given would not change the network CSC to ATT like it should have in order to work properly.
I was able to get to the manual CSC change menu through the dialer code with a TFW-att sim card (yes, while on oneUI 3.0). I suppose the menu is locked out when other csc's are active.
This allowed me to force change to ATT's csc, then place my FN sim in the phone. The kicker? I had to toggle "do not auto update CSC based on sim data" in the menu to get this method to stick.
Things are grand, working fine, but i got curious as to what options the other csc's had to offer. So i start flipping through the list and end up landing on.....you guessed it..... XAA.
Without thinking about it, i ran it, the phone rebooted, and now im screwed. Flashed the ATT rom with Odin- no change. Factory reset? No change. I messed up BIG.
Finale / TLDR
If you didn't get what just happened there, I used a specific sim card to enable a CSC a menu that uncle sammy does not want you playing with. Proceeded to disable auto CSC changing by SIM, then walked back into a CSC that does not allow me to open said menu. Thus preventing my phone from working fully on ANY NETWORK ever again. With root impossible...
Side notes that failed: Tried fac reset/ tried firmware flash/ tried samkey (no android 11 support)/ tried force change from network side. I hope im not out of options?
