I tried both methods but none of them worked :/

some suggestions...
Sorry you're having this trouble, qnfk... and that your welcome here by the above poster was not only less than friendly, it was unhelpful, since the solutions he recommended are for a different problem, namely unlocking a carrier lock not the region lock. Your phone is likely to have only one or the other.
I noticed that you have found the thread, Region Lock Unlocking for i9500 S4, though it hasn't become very active yet.
I have 3 suggestions for you:
A. Type *#12580*369# on your phone to check RF Cal for the date of manufacture and *#1234# for the firmware version codes for AP, CP & CSC.
B. Follow these directions to access the MCC blacklist in your device's customer.xml file:

...use a file manager app like ES file explorer to look at the file /system/csc/customer.xml and then look for the lines starting:
<Settings>
- <Main>
- <Security>
<NbNetworkLock>...

C. Read this entire thread: Check the countries that you can’t use your galaxy S4 in. Consider posting your questions there with the above information. It's a fairly active thread and I'm sure you'd be welcome... in fact, you'll find that the OP referenced your situation last week.
Your circumstances are unusual since Asian phones are officially supposed to be region unlocked. If you do post on that thread, you might consider also providing information about the background of your phone, such as where you bought it, how the seller represented its origin to you and whether or not it had a region-lock sticker on the box.
Good Luck!

Thank you so much for your help I'll continue to post my problem in the other thread.

almost giving up on GT-I9500
I have a GT-I9500 that is Region locked(Middle East),I tried almost everything but nothing works for me.....H*ll I don't mind paying for unlocking codes,but i read somewhere that Region Locked is different,so buying unlocking codes might not really work,the phone comes with the new bootloader(phone made 2013.10.13),pls if anybody has a solution/suggestion or even a reliable website that can provide genuine "Region Unlocking codes" should share.
what i ve tried so far but still did not work
1-Region unlock app by @Chainfire
2-Try entering service mode by *#0011#
3-Root and install a custom rom(Crash Rom)
4-Terminal Emulator (to calculate unlock codes)
5-Change the Modem (tried all the modems,more than 10)
If anybody can help,pls kindly assist....
Thank you all

Region Lock Unlocking for i9500 S4

Hello guys,
Does anyone work on unlocking the new Region Lock for i9500 ?
I know some work being done for note3, but what about s4 ?
I'm stuck with a US locked i9500 (outside of US). The "activation" with US sim did not work (it worked in US but once i'm abroad it is locked, but even here works with american sim). I can test things on my phone / provide logs if needed.
thanks,
Im actually also having the same problem. I even tried unlocking through code and using apps,didnt work for me
maybe this works
I haven't tried but you can check these methods.
1. I heard that root is needed together with the app like region lock away.apk by chainfire
2. Further, it seems that purchasing a SIM unlock code not only unlocks the device’s SIM, but also its region.
3. With root explorer navigate to system/csc/customer.xml*file (if you can)
It will contain list of Network Lock fields including one for your country MCC for e.g for Thiland it's MCC is (520) and China MCC (460).You can find your country mcc by googling.
Thailand NetworkLock field in CSC file might look like:*<NetworkLock>520BB</NetworkLock>.
China NetworkLock field in CSC file might look like:*<NetworkLock>460BB</NetworkLock>.
This would help understand what might be the reason for the change in lock state whether it is a change in the regional NetworkLock list in the CSC .
Find your country in which you are in respective mcc code and search in the xml file if you find it delete that mcc code line and save it. But please don't forget to make backup in case if it doesn't work
Tell me if it works otherwise some other person will surely help you guys.

1. Tried the RegionAway app v1.3 by chainfire. it was sucessfull but nothing changed. it is still locked. ( the app is designed for note3 as far as i understand)
2. i've heard about many who tried their luck with purchasing codes - it does not work. Also confirmed with unlocksamsungonline.com it wont help
3. my customer.xml does not contain the string "lock". This is probably because i've downloaded and flashed an official version of my local firmware. (thought maybe it will unlock) - it didnt. Also tried to flash older modems - or it does not work completely or still locked.
Also got a comment from unlocksamsungonline.com that "I9500 is Andriod1 model with new EFSv2 security" and is a problem ....

[Q] Not registered on Network Please help

I've Boughten an unlocked Galaxy Note 3 SM-9005 on ebay. To use for straight talk in the United States. The first sim card i had in it was a normal sized sim card that i had cut (instead of micro) And after fiddling this sim card had worked from 4-5 days. Then i started to get the error message "No service" and "Not registered on Network" I had figured the sim was probably the reason to why i was not being allowed to call or message. So i bought another brand new micro sim card. And then put that in (Again with straight talk) and i am still unable to call or message. I have checked my imei number and it is the same as the one on the back of the phone. I have tried to re-register on the network within the settings on the phone. With no luck whatsoever. I have noticed that the CSC is not correct for the united states. And in hopes of fixing it i rooted and installed a custom rom. (IMEI is still the same)
If someone could please help...I am Stumped[/FONT]

Head over to Sammobile.com find the right CSC/Firmware for your country and flash it Via ODIN on the PC.

On sammobile there is not a firmware for Sm-n9005 that is in the united states. Or thats what it looks like

Given the details that you have provided so far the most likely scenarios that I see are:
1) there is a mechanical problem on the SIM contact
2) the seller was on some form of a contract and has reported the phone stolen, so the IMEI is now blocked on some or all carriers.
DO NOT MINGLE WITH THE FIRMWARE at this point (and also disable any automatic updates of the firmware).
Also if you want further technical info (and not just guesswork) you should post the output from *#1234#

It really does depend on the issues xclub has brought up.
If it was me, I'd rule out SIM issue (the card itself) due to having a replacement, although it could be an issue with the SIM Tray.
And if it is used, then yes it is possible that it has been blocked by the original owner.
EDIT : Do you guys in the US have an IMEI checker for blocked IMEI's etc? in Europe we do it's called CHECK MEND.. Might be worth having a look or alternatively give your network a ring, they'll know for sure.

I Contacted Straight talk and they confirmed that my imei was not blocked. And if i were to download say this firmware sammobile.com/firmwares/1/?model=SM-N9005&pcode=XSI#firmware would that make any difference?

Ok so you have the same firmware as me, I am using BTU which is UK (I am UK) - So your CSC does indeed need changed to match you for US use - -- Firstly does your network support the available frequency required? (do you have LTE?) - If so you can change you CSC to your required region But another factor --- are you aware of region lock? has it been disabled that you know of? - this could cause some issues if it hasn't been deactivated - I'm not sure when changing CSC/firmware if it reactivates region locking or not
EDIT: I think only T-Mobile supports the N9005 in the US ( I could be wrong) --- Need a US user to chime in here I think to be 100% sure!!
Going with an Unknown carrier on CSC/FW- May not solve it

I could try it tho. I'll tell you the results once i finish. And Verizon And At&t are used by straight talk. And it looks like they both have the note 3. And when i purchased this phone, It said that region lock was disabled

Don't see why not, plenty of people are buying them and plenty selling them.
majority of users have no idea what Knox is tbh, it's ultimately up to you if you disclose this to them or not.

That looks like EU version. Since somewhere else you mentioned that you rooted then the next thing to try is Region Lock Away:
http://forum.xda-developers.com/showthread.php?t=2470551
since the phone might now be "hit" by the EU region lock (an even simpler test would be to insert an EU SIM just to see if it registers on some network for roaming). If RegionLockAway fixes things you can then see what version of firmware you want in order to get LTE from your carrier.
If you want to sell the phone - being rooted might even be a plus, but having Knox 0x1 is certainly a major minus.
I did get region unlock and it did not work. And when i try to install the unknown firmware i am unable to flash it with odin i get all sorts of errors (I tried two of the unknowns) BTW thanks for the help
Please help, I flashed it to Android 5.0 and I did root for it and used region unlock app and still I face the same issue, please help me

SM-G900R4 - US Cellular Galaxy S5 Unlock

Hello everyone,
Sorry if this was posted already - I am typing this up in between other projects and I wanted to put something out here so I wouldn't forget. This last weekend, I purchased a used Galaxy S5 CDMA phone branded by US Cellular. I searched and searched for a way to unlock it but I was not able to find anything that worked for me. My phone is currently running Android 4.4.2 and none of the *# dial codes would do anything for me. Finally I was near a local US Cellular today so I brought my phone in and they unlocked the SIM for me so I can use it with other carriers. I haven't had a chance to go through the phone yet after the unlock, but I plan on looking at it tonight when I get home to find out if I can figure out how it was unlocked so I can share that info with anyone on the site who would like to unlock their SM-G900R4. I'm hoping that during their unlocking process, the hidden menus were left visible so I can look at the phone's file structure. I'll report back as soon as I know more.

Just a quick follow up... I didn't have a chance to go through my phone extensively last night, but I did see something that may or may not be of interest. When I got my phone back after being unlocked, there was an icon for mceFramework. When I clicked on it, it ran in the upper corner of the phone and when I swiped down it said it would be uninstalled. From what I have read about it, it has really nothing to do with the unlocking of the phone though.
Depending on what time I get home tonight will determine if I get to really dig into the phone tonight or not. I'm hoping there is something I will be able to find that will be useful. The US Cellular phone is a bit different though, as I mentioned before regarding the *# codes... No matter what *# codes I try, they do not work... even something as simple as *#060# does nothing on my phone - even after being unlocked. If I find something, I'll report back.

Hello, I came across this thread and just thought I'd share how I was able to unlock my Galaxy s5 Mini (US Cellular). I tried just about everything, but what finally worked was simply flashing the stock rom which can be found at the sammobile site. Use 'Odin', instructions included on the website.

Hello -- stock rom by model number. I think in most cases this is just stock Android for the carrier of specified model, minus bloatware and network lock. Well, I correct myself -- there may be some bloatware, but certainly less than what was there after performing the factory reset. The link to 'sm-g900r4' rom is at sammobile(dotcom), firmwares, search for model number -- and download latest version.
In my case, phone model is 'sm-g800r4' (US Cellular). Everywhere I looked online suggested that I had to contact US Cellular and request instructions for unlocking, but they will only do this if you have the original sim card. So, I finally flashed the stock rom using Odin, following very basic instructions (included on the rom site). After flashing, I still had the US Cellular splash screen, but my verizon sim suddenly worked with the device. Next step for me -- root and replace that ugly US Cellular splash screen with the gorgeous lollipop boot animation. Very nice.
If you need assistance with specific instructions let me know, and I can provide a quick summary.
Simple instructions, great site to join for US Cell users.

I Opened it and it has the Sim Card Slot, Hopefully it is GSM which is what I need. Please help. Thank you very much.

Did you ever figure out a way to unlock your phone?

will flashing an unlocked device with another rom be causinng a problem ?

hey i got my note 4 (N910P) from Texas and brought it to my home country India so i just read the message but i wanted to confirm that if i flash my sprint note 4 (N910P) with a different country rom or any other rom then will it be causing any problem ? i have unlocked it but i am now facing the issues with the carrier featured applications so it is unlocked and ya of course i will keep the model no. in mind for finding the rom then it will be good to go right if i flash it with the same model no. the country doesn't matter ? also tell me how can i become sure of that it is unlocked
TIA dude
You should probably ask this in the Note 4 forum of XDA...
And no, the country doesn't usually matter as long as you are using a ROM that wasn't edited by a carrier (a lot of ROMs on sammobile, for example).

Well, one simple way is get another active SIM card, insert it and try to call someone. If it works, it's unlocked. If there's an error, it's still carrier-locked. Other option is installing GalaxSim Unlock, and open it - if it offers to unlock your phone, it's still locked, but if it says anything like "lock is not present" or "SIM Lock Status: undefined", it's unlocked.

G950FD from Iran (THR) with pre-installed Persian/Iranian Calendar

I bought an unlocked G950FD which turns out to be CSC THR (part of OXM) so should mean it's from Iran. I have found it generic enough in almost every way to be used internationally (in English) with two noticeable exceptions that i'm trying to solve.
1) there is pre-installed Persian Calendar in the OS which appears after the Gregorian date on the AOS and lock screen. I also noticed this extra date appearing on the Samsung Calendar app under the western date, but i don't use this app at all so can easily ignore. The AOS and lock screen is seen all the time and would displays: "MON, JUNE 5 (KHOR 15)". I looked through every settings on the phone and many forums online, and there is no software way to turn this off.
I thought a potential solution would be to replace this stock ROM with another region since any of the multi-CSC OXM firmwares should be compatible with the phone. So I tried to flash another region using Odin. I tried Singapore (SIN and STH) and completely reset/wiped the phone two separate times. However, despite flashing a large (almost 6GB) file onto the phone it still remains in THR when i looked in settings. I guess I misunderstood the purpose of different firmware regions, I thought i would be changing my phone's existing firmware to another region and get a different set of default apps and localization behavior. But the Persian date is still there on all the same screens.
Am I flashing the rom incorrectly? Is there some setting that i omitted that would give me the desired result of a Singapore OS? Any other ways to change CSC and get rid of unwanted parts of a regional firmware?
2) Another problem is when i receive calls on my local sim card, the phone number shows up without the country code, but if i store my numbers (on Google contacts) in "+<country code> <phone number>" format then the contact is not linked to the incoming call.
Apparently this is fairly common with international phones being used in another market. There is a workaround where i can edit my numbers on google to not have any numerical country codes but instead use the flag drop-down menu on google to indicate country associated with the number. I'm ok with that solution but is there another way? Would flashing a regional firmware that is my location solve this? The region that i intend to use the phone is not part of the OXM multi-CSC list of countries since they only sell the snapdragon variant here.
I would like to find solutions that would avoid root and custom roms, but if that is the only option here, i am not against going down that route.
Thanks a lot in advance.
My eventual solution and what i've learned.
So as i described above, i tried to flash many different versions of G950FD or G950F firware with multi-CSC OXM, but never saw my CSC change from THR. Nothing changed on my phone despite installing large files through odin which was always confusing to me. For the record, i tried BTU (UK), STH (Singapore), and SIN (Singapore) which are all part of the OXM.
I learned from another forum that the sim-card installed matters, so i was just trying different non-middle-east regions by picking UK or Singapore but my actual home region does not support this model/cpu variant. I don't have a sim-card from any OXM regions, only Hong Kong and US ones.
Then i found an old Australian (Optus) sim card from a trip and found a G950F firmware version with CSC OPS on Updato. Not part of CSC OXM but same PDA/Phone version and was told it's safe to flash. When i flashed that firmware with the AU sim card installed, i got the AU OS and all the old regional apps were gone. I got some Australian ones but nothing i can't uninstall. My caller ID problem also seem to be fixed. So i consider the problem fixed.
In all of this, the PDA version numbers were always the same (AQDG), so i'm still a bit unclear as to what the CSC file is specifying and doing.
Am i correct to assume that multi-CSC OXM firmware contained regional apps/settings for all the various regions but without a sim card installed to tell it which one to pick, it kept selecting the factory region of THR? And when i flashed the Optus firmware, did i really need the sim-card installed? Would it have changed the firmware to OPS because it's outside the multi-CSC OXM group?
You live in Hong Kong, right ?
I do too, and have a UAE S8, and Samsung Pay doesn't work.
Does your working around things allow you to use Pay, or you get stuck on the splash screen as well ?

Yes i live in HK, so with the AU Optus Firmware I got a AU version of Samsung Pay with all AU ads and suggested businesses. I can get past the splash and login using my normal Samsung Account, which shouldn't have a region. BUT so far i haven't had any success adding any of my HK credit cards, i assume it's a version compatibility issue. There is no way to pick which regional version of Samsung Pay on the Play Store, so i guess it looks at your phone's origin to determine that part of the app.
I am not that keen to use Samsung Pay, but of course interested to know if it is possible. It says to call the banks to get my credit cards added, so maybe there is still a chance and i will post if i do succeed.
Do you think Samsung Pay is particularly good for HK? Would using Android Pay be comparable here? I'm not that experienced with mobile payment apps in the past. Seems like the membership card storage function will still work on my Samsung Pay so at least i have that and can slim down the wallet a bit.
Hey there buddy,
Finally found a thread that represents my problem also, in my case i have a s8 G950FD that shows the same thing on my lockscreen, by me it shows (KHOR18)!
Is there any way around it, i mean a fix?? I would greatly appreciate any help
Yes that's the Iranian calendar date so the day will increment everyday. Khor is abbrev for the current month.
Yes I have a solution (read my second post in thread) but involves flashing with a sim card and 950f or 950fd firmware of the same region as the sim card. You will need to reset and erase phone data.
If you need help flashing stock firmware there is a long thread on this forum and where I found the answer about how the sim card installed might make difference.
What region/sim are you currently trying to use your s8?

Hey there again,
Thank you very much for the time. I am in SE Europe, to be more precise Republic of Kosovo. My SIM is from Kosovo ( we are considered i believe to be in Europe carrier wise)
I do need help flashing the phone as i have no experience whatsoever i just recently switched from Iphone to Samsung, this being said i must also mention the fact that i would definitely need help. I dont want to mess up the phone i just got it like 2 days ago
Things to consider:
- You can flash both 950F and 950FD firmware on your 950FD.
- You need to find your desired firmware. And that region needs to match your sim card, use Updato or SamMobile but the firmware package is a >3GB file and takes a while to download. Make sure you only look for versions for model 950F or FD.
- You will need to download Odin and Samsung usb drivers to flash the firmware onto your phone. Follow the thread "OFFICIAL STOCK Firmware-update (Odin) thread Samsung GALAXY S8 SM-G950F" for the guide.

If you decided to go the "SIM card CSC" method then follow this step by step:
https://www.sammobile.com/forum/showthread.php?t=37711
But I personally think you should do it through flashing a firmware with odin but properly and pay attention to step 6:

Yes, if you are changing country/code of CSC, then the system needs to recalculate the partitions.
And don't forget no short cuts! Every step should be done.
Good luck.
ooo man this things is killing me now the problem i have after i have rooted the phone is that the computer wont recognize my phone in download mode ??????????
Hey Peeps,
