Hi guys , i dunno if this is the right section for this question but i'm a newbie here , i got two sm-g925r7 locked to nTelos i think and i want to unlock them for international gsm use outside the u.s , is this possible ? if yes do you know a guy who can do them at a reasonably price ? since this can work on sprint cdma phones i don't see why it can't work on nTelos since they are both cdma ? correct me if i'm wrong , i need your help guuuuuys please.
How do you know if they're locked to nTelos? Did you try putting in another carrier's Sim card? Uru
nothing happens
i know couse i bought them on ebay and the sellers stated that in their description , and the sm-g925r7 is for cspire or ntelos only ? i tried using a foreign sim card , ( i'm outside the u.s ) and nothing happens , phones search for network 2-3 secs and then they just show that little barred signal icon on the top right corner
Well on the nTelos website it says all android phones are unlocked so I dont know.
checked that

You can unlock by enabling service menu
-Insert 4G sim card
Dial *#27663368378# -This will put you in service mode
* tap UE Settings & Info > Settings > Protocol > NAS > Network Control > Band Selection > Choose choice 7 “LTE/GSM MODE ONLY”
Restart

you can enable service menu by rooting the phone, tested on android 5.0.2 and 5.1.1

Ok I'll root using the sprint rooting as I've tried this before with success, but first I'll downgrade them to 5.1.1 and hopefully i'll get past this ,since the settings will be set to lte/gsm why wouldn't it work with calls ?

I hope flashing to sprint version or trying with different bootloader / modems could be the solution, I have not found any guide yet
Ok so i rooted the phone and used root explorer to enable service mode , restarted the phone , opened service mode and selected lte/gsm only , restart , phone asks for sim pin and then nothing , no data sms or calls
I am also interested in this unlock but haven't found a solution yet.

after enabling lte/gsm only, restart and go to settings > network mode > select lte/wcdma/gsm. try with different carriers and 4G sim cards to get signal (mine is working on Claro only, other carriers show "Searching" or "No service" )
If this is the go25r7wwu3cpc1 how did you root?? I'm on firmware 6.0.1 can't find root anywhere..

you tryed to unlock with z3x box?
g925r7 is currently not listed in Z3X box support list.
need rmt_storage patch to make changes to bands inside the phone.
inside item 1787 (3G GSM bands), this item has no support.
Reason why it doesn't work for calls is because VOLTE is not enabled by default in CSC
usually a device like this will fall back to 3G when making calls on GSM networks. Thus the reason why calls aren't working.

I m from pune and,Recently I activated airtel 3g in my samsung galaxy ace... Bt problem is that I m not getting 3g signal.
In samsung galaxy 3 there are options like dual mode/3g mode,bt in galaxy ace when I go in mobile networks there are this options : enable packet data, data roaming, access point name, mobile operator, use only 2g networks.according to airtel customer care I should chk on enable packet data and unchk on use only 2g network options I did so bt still can't get 3g,signals..
I tried to use 3g signals in many places in pune..bt still I m jst,getting edge connection
Are you sure there is 3G network? If so, did you make sure that in APN list there is the one provided by your carrier for 3G ?

Have you checked your APN settings?
Uncheck 2g mode only. If still you not see 3g symbol at left side of signal then in network setting go network operators and search available networks and choose airtel 3g.if still not get then go into keypad and type *#*#4636#*#* and select option phone imformation and in that you see gsm auto selected. In that choose wcdma only and press turn off radio then press turn on radio now press home button(not back button). You will get 3g. If not then reboot. I hope this will help you
You are using the wrong ROM or MODEM file with a Band Operator that's not supported for your company. Review the frecuency of your operator for 3G. Then, flash your phone with the correct ROM.
Hello everybody!
I installed the rom version 2.3.4 (vivo - Brazil) in my galaxy s5830L (3g 850/1900MHz). My mobile carrier works with 3G 2100MHz, so I can not connect to 3G only 2G (edge).
Do you know if there is any possibility to enable 2100MHz in s5830L 3G?
Thank you!

Now I m really getting frustrated by this problem I called Samsung helpline they said for using 3g in some mobiles u have to do a Software Update in Samsung Service centre after which u will get that 3g/dual network mode option in ur Mobile network settings like other mobiles, bt I doubt if they can really help me bcozz about 2 months ago I had already done a Firmware update earlier its version was KC1 and after update its version is KC7 which i think is the latest version of Firmware available in India for Samsung galaxy ace. I said this to Samsung technical Support but they say that Software update and Firmware Update are completely Differnet things…
So I want to know whether this Software update and Firmware update are this realy different Or its same. I have also Noticed one more thing in “Samsung galaxy Fit “also there is no Option like 3g/dual Network mode to Enable 3g!! is that option diabled in all galaxy Ace & Fit models or is it only in my cell???

After selecting wcdma only turnoff radio and again turn on radio then push middal button called home button. When you doesnt want 3g mode tick on 2g mode only.
I also suffer from same problem when i use bsnl3g. You should camplain in airtel servise center because it is not fault of mobile but fault of network provider. If you want to chek then insert other sim and uncheck on 2g only and select access poit . If you get 3g then your mobile is not in fault. I want to know that you get 2g internet on that airtel card? And you choose access point?if not then select access point

dude i think u are not reading my posts completely..i can say this bcozz right from my first post of this thread i m mentioning that with same sim card of airtel i m getting edge connection..and the problem is not with sim card its with cell itself bcozz when i tried same sim card in other mobile i immediately got 3g signal in same area..that bcozz after lots of search on google i saw that many are facing this problem of 3g not connecting..its due to a software bug in froyo 2.2.1 so people say only way to solve this problem is we will have to upgrade our froyo to 2.3.3 or 2.3.4 this might solve our problems bt still i have some queries which i have to clear like see if u can ans them :
1. which one will be better to go with android 2.3.3 Gingerbread or 2.3.4 Gingerbread for Samsung galaxy ace I mean which one has less problems and will solve my 3g problem!!
2. after unofficially upgrading to 2.3.3 or 2.3.4 will I be able to officially upgrade to 2.3.5 through kies in future.
3. For upgrading to 2.3.3 or 2.3.4 is it necessary to root the phone..
4. how much time does a whole upgrade process takes if my internet speed is Minimum 1Mbps…
5. How to come back to 2.2.1 Froyo Default version from 2.3.3 or 2.3.4(Steps with video or Img link will be very helpful)
Update to 2.3.4 is realy easy and not require root. You should first download 2.3.4 flash file and after download use odin to install flash file. When official update comes you can downgrade your phone to froyo so kies update it to latest version so chill.
My email is [email protected]
contact me i will explain you how to update to 2.3.4 and where to download

2. If it is possible, how we can change, upgrade to new firmware ?
p.s. I have upgraded it to GINGERBREAD.UBKP7
Please help me to solve these issue,
Thank you before hand.
plese help me with problem above
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.

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.

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.

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?

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.

can you share step by step?
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.

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

Go to Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock >then I just get this message....MENU NOT EXIST PRESS BACK KEY Current command is 186
thopughts please
Very difficult to understand you, but flashing a firmware has nothing to do with network lock.

If your phone is unable to connect Virgin network then how come it asked you to download config settings. Are you able to call any one? If not then flash the correct firmware. (Refer sammobile)
If you are able to dial out and only internet is issue then google and find out virgin mobile internet configuration and do it manually.

I can send an mms message to another phone and I can use the phones mobile internet as now the mms apn and mobile internet
I can not receive texts on this phone that's why I am not getting the virgin settings

When you installed the rom (BTU is fine its a generic UK Europe firmware so any sim should work) did you do a factory reset to clean the phone of all the custom stuff, if not then do that, Settings > Accounts > Backup and Reset then Factory Data Reset if you are running Android 4.3
This will wipe the phone data and settings to return it to factory state of the BTU rom, move any pictures, music etc from the internal storage to your external SD card or you will lose it
When the phone reboots you will need to set it up from scratch as if you had just got it.

hi this sim works flawless in my chinky phone
is there any way I can find out if my phone is barred and if it was barred would I be able to use the phone for mms as it can send mms?
sorry if this is stupid btw

Don't know how to check if the phone is barred. As your phone registered on Virgin network, I don't think it's network-locked.
Try a sim from a different network to see if you can replicate the problem.
Maybe try factory reset and setup without the sim card in. After the set up shut down and pop in the SIM, then restart. Make sure mobile data and wifi are off when you restart.
It is odd, because it should automatically configure without the need to download anything.
ok thanks will try that
ok done all that phoned virgin support
they are suggesting it is locked onto the previous network
thing is I don't know what the network was before so I guess
ive got hold of a small wifi tablet for the boys to play with
unless someone can point me in the right direction?????

Use KIES to recover the original phone firmware,
Start Kies do not connect the phone turn that off and remove the battery
On the menu bar go to Tools > Firmware Upgrade and Installation them follow the instructions
This will put the most up to date original firmware version on the phone but may well sim lock it if it was previously locked to a network
Hi XDA ,
Am new in the Forum & First of all thanks to all of you for helping the forum and people. I'm having difficulties and I cant seem to find the way to fix this(its been 2 weeks)
My problem is the following: I have a Samsung Galaxy Note 3 details:
software version: N900PVPUBMI3
hardware version N900P.00
Status: network: Digital roaming
mobile network type CDMA-AxRTT
Android 4.4.2
KERNEL:[email protected]#1
A friend bought me this phone and called my carrier METROPCS and made them set up the phone so I could use it. they asked him for imei and sim number. He was able to use the phone and 4GLTE(he was doing this to verify it was unlocked) later on he gave me the phone and I had to do the same procedure he did but first I did a factory data reset.
After it I wasn't able to set it up again.
I've noticed that APN SETTINGS has disappeared from the menu, cant search for networks, when I load IMEI it no longer shows the imei but it shows MEID B0000000 and besides all of this I have a message that says SIM CARD INVALID.(but the sim card works perfectly on my other phone)
I will all my life appreciate if you help me with this matter please!
PS. phone is rooted as far as I know(root check on Google play store said it was)
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

You might try installing this app it find/gives all the hidden info on your device http://forum.xda-developers.com/not.../app-one-click-hotspot-enabler-menus-t2816159 it will give you APN's MEID AND IMEI . All you have to do is download to your PC, it my download as a zip file. Just use 7zip and rename it to an apk, then copy and paste it to your internal sd card via your charging cable. Then click on apk and install. Enjoy !!!
BTW your MEID is on a label under the battery !!!

Hi Jim/XDA
I'm still not able to connect to the network. Regarding the IMEI on the back part i know its there however what im saying is that im not able to see my imei through command when i dial *#06#
i as well had this errors today when i woke up:
: LTE:ESM-x EMM-14(ive seen this error when this issue started but it dissapeared and it came back know)
data roaming: you have lost data connectivity because you left your home network with data roaming turned off.
On mobile networks i remember i use to be able to select many(GSM,CDMA,etc) now in network mode i only see 2 options LTE/CDMA,CDMA. Currently LTE/CDMA is selected and if you just look at the network mode option without actually opening it it shows CDMA/LTE/EVDO.
Also when i opened the SCRTN it shows on black screen.
I tried to do some minor changes on Galaxy tools like the SIM UICC UNLOCK all mps,sales,default code on XAS. Factory & keystring ON. MSL/SPC show 222222.
After i did SIM UICC UNLOCK and restarted phone know took away all errors but i see the signal bars faded out and with a little red x on top of it. I've read the manual but im still wondering if there might still be things to set on a particular way that are not specified on it Can you please help me set this up properly?

Is this a Sprint variant? If so, you shouldn't have factory reset the phone. It looked like the phone was previously flashed to MetroPCS and by resetting the phone, it removed all the carrier data.
You will have to reflash the phone to get it working again.

Hey guys, for those who need to edit an APN (Access Point Names), there is a little secret.
Go Settings, and scroll down the list. You will find a search box. Type there Access Piont Names and here it is.
The steps above are neccesary, since APN setting is hidden.
Hey guys, recently I've got an Alpha SM-G850A which is for AT&T. I live in Iran and the phone has been unlocked to work here, I was trying to get the Android Lollipop 5.0.2 for my phone. so first I tried to get the update from AT&T software update by phone, but it says that there seems to be no updates available for me, nevertheless on the net the guys claim that they've got the update, is it due to my location in Iran and my internet IP? (I used VPN too but again, no updates). I tried to get the firmware from Sammobile.com too, but there were no firmwares detected for SM-G850A. Can someone help please?:good::good:
BTW, I've got the cellular data from my operator, and it works, but I can't select which type I wanna use (2G, 3G or 4G). I mean there's no options in the phone settings to select the data connection type. NEED HELP!

Even tho the phone is working on other networks you will still need an at&t sim card to update it. There is no way around this as far as i know.
Type below code in dialer and select Device information. Now, if you scroll down you will have the option to change network type.
Code:
*#*#4636#*#*
