I purchased my SM-G900F refurbished in the uk couple of years ago. I’ve been having intermittent but persistent issues with calling, mobile data and signal.
After some digging I’ve found that the phone CSC code states it is from portugal (seller stated it was a uk phone )
PDA shows UK code and I set the phone up as UK.
This leads to a few questions:
1. Would this cause any issues like those stated above?
2. How would I change the CSC to UK code & what are the potential drawbacks?
3. As I don’t know if the phone really was factory unlocked, will I lose my sim unlock by doing the change?
Phone is running stock 6.0.1 firmware.
Any help is appreciated.
Many thanks,
TLA

Hi,
I'm new to both this forum and android, just switched from iphone and already running into the same dead end that I was trying to avoid. Hope to get some suggestions on solutions before trying sell it off again...
I bought a second hand SGSII which is from the UK (T-mobile), and with the help of my brother who has a SGSII and have been on android for a while, I debranded/rooted changed ROM, Kernel and Modem firmware. Before doing this I noted that it did not work with the network I am on but it did with another (both Swedish). After rooting etc I tried again, still does not work (I've tried several sims from my provider, none of them work, still only the other provider). I tried using the Sim Unlock app on Market but it is of no use: It DOES NOT ASK for a sim unlock code on start up. In fact, the unlock app worked and gave me such a code but I cannot use it. Also, I tried plugging in the code using a few of the call codes but it was of no use. And when I put *#SIMLOCK# into the phone dialer everything says 'off'.
Does anyone have any idea of what to do? I cannot go back to Samsung as I do not have a receipt. I hate to think that I have to end my use of Android before it ever started but I have searched my problem for days on end and neither me nor my brother can think of anything.
Any help most appreciated!
Cheers Matt

I am confused did you buy an unlocked phone . If not did you get it unlocked .

JJEgan - sorry if I was unclear. I do not actually know for sure, but as I have never seen the screen on startup where it asks for the unlock code I suspect that it must have been. It now - same as it has been for as long as I have had it - works only with one network which has nothing to do with T-mobile (on which is was originally).
I only know of one way of unlocking, i.e. the unlock app on Market. If there are others I would be very interested!
Phone may require you to enter the networks APN settings manually .
You may not have the correct CSC file for your network for automatic connection ,

Hi - been busy the last few days and unable to try getting the phone to work. I cannot enter the APN settings (which should only have to do with internet?) as I cannot connect to any network in the list - I get "unable to select network". I've tried multiple official firmwares with both only NEE (Nordic) CSC and multi-CSC (where I chose NEE) and none work. Any other ideas?
Cheers
Hi there,
I rooted my phone. I've installed Cyanogenmod 7 and enjoyed it. However, it is SIM locked. I purchased an unlock code... but now I can't enter it.
This person had the same problem:
http://forum.xda-developers.com/showthread.php?t=1313393
Cyanogenmod does not prompt to unlock even with a foreign SIM card.
The solution was to revert to a stock firmware. Which is great... except for the fact that my phone's model number is:
i5500m.
It's the dreaded Canadian version. I can't find firmware for it anywhere. I've tried Check FUS:
Product Code: GT-I5500YKMVMC
No firmware info retrieved for given data.
Generally it seems like I only have two solutions... and one failure.
The first solution is to find a stock firmware for this phone. Or receive a backup from someone who has the stock firmware with Clockworkmod.
The second solution is to enter the unlock code without the prompt. Is there a way, an app, or a hack to do something like this?
My failure is to accept that there's no reverting. But I don't really want to do that.
Oh, and thank you for welcoming me into your forums. XDA Developers is a really amazing site. I've thanked it plenty of times for saving my ass.
Thanks for your time,

Look closely at the latest changelog and notice that point 12 states -
"Network: SIM lock messages will no longer be ignored. This may help people who have problems using SIM cards that require a PIN unlock."
Good luck

Thank you so much! I missed that update by only two days. I'm sure this will help many people.
I'll edit this post with my results once completed.
Thanks again!
Sacrosaint.
---------------------------------
Results:
So I updated the ROM. I did not do a data-wipe. I inserted a foreign SIM card. It says it's connected but I'm not getting any service... I don't believe it's unlocked, as I haven't entered a code yet.
Perhaps I should do a data-wipe and retry. I'll repost afterward.
---------------------------------
Potential Final Update:
Odd! I inserted a Rogers SIM card into my phone running CyanogenMod and although no unlock code appeared... it worked. Also known as: my phone is unlocked.
Some interesting thoughts concerning this:
My phone model is i5500m. It comes locked to Bell or Virgin Mobile in Canada.
Upon trying the bml5 unlock method, my code came up as "01234567." Others experiencing this problem concluded that the phone was hard locked.
However, it would appear that flashing this ROM effectively removed the SIM lock. That means that originally, the SIM lock was a part of the firmware. That is slightly scary. I wish I would have come to this conclusion earlier, however, as I paid a premium of $40 dollars to unlock it (at least I supported a local business.)
So: for i5500m or Canadian Samsung Galaxy 5 users to unlock their phones, they must simply root and flash a custom ROM. Originally mine was from Bell, and it has worked with a Rogers SIM card. I'll possibly update this tomorrow when I try the phone with a Koodo SIM.
Hope this helps someone out there.

Sacrosaint,
I have an unlocked GT-I5503YKAINU running baseband I5500LUYJP2 and ROM CyanogenMod-7.2.0-RC0-galaxy5-v1.9. I inserted a Virgin Mobile Canada SIM card and do not get Service. With a Rogers SIM card, I do get Service. I spoke to people at Virgin and they said it's because my phone doesn't support HSPA+. The reason it works with Rogers is because it supports GSM.
I'm wonder if there's a way to install the baseband firmware from GT-I5500YKMVMC and still use CyanogenMod-7.2.0-RC0-galaxy5-v1.9?

What the representative said was true.
Virgin is both HSPA+ and CDMA. The Galaxy 5 IS a GSM phone. Its radio will not work with other frequencies.
You will want to go with Bell, Rogers, Telus, Fido, or Koodo, the GSM suppliers, my friend.
Hi Guys,
2 months ago I bought a Samsung s5 in Hong Kong.
While travelling through South East Asia this device worked fine.
While traveling through New Zealand (Old home) this phone worked fine.
While traveling through America (New Home) this phone worked fine for the first 2 weeks (on the metroPCS network).
The problem:
Randomly after 2 weeks the s5 stopped connecting to the metroPCS mobile network even though the network was available (btw metroPCS uses the T-Mobile network). It gives errors such as network not available or cannot register with network.
Things I have tried:
-Im sure the APN settings of the phone have not changed and I have double checked to see if they are correct.
-replacing the sim card with another does not fix the issue
-soft and hard reset of the phone does not fix the issue
-Getting metroPCS to refresh the service on this number does not fix the issue
Other important info:
-This phone was purchased in hong kong but it is from the Philippians according to Kies's firmware information (XTC is the country code)
-It is running a custom allianceROM that must have been installed by someone in hongkong
-The device is rooted (superuser app installed)
-the model number as shown in settings is g900f BUT when attempting to flash with odin the phone displays g900t and fails to flash the latest Philippians verison of kit-kat
I have 2 questions:
1. Any ideas why my network connection has suddenly self destructed (and how to fix)?
2. Would flashing a stock ROM to my s5 help? and if so why is there conflicting information on which model I own (g900t/g900f)?
Please help. I do have some know how on flashing android devices but i've really hit the wall on this one guys!
Cheers,
Yetti.:cyclops:
It's not uncommon for the model # to be different with a custom rom as that is a very easy thing to edit in the build.prop. It should tell you under the battery which one it is. As far as the network issues, check to see if the baseband and IMEI are still there and not listed as unknown or incorrectly. It's possible you could get away with flashing the appropriate modem that matches with your update and that might work better in this region vs the previous one.
Please list the Alliance rom version and baseband version here in case it's relevant to your issue.
More info
Im not sure if this helps but looking through the build.prop file in the system folder my ro.product.local.region=GB
When in recovery mode the region is set to XTC (Philippians) using mutli-csc.
Also my IMEI number seems ok and is NOT blocked.
Cheers. Yetti :cyclops:
Baseband and rom etc
Thankls for your reply!
Sorry when you say "under the battery symbol" do you mean in /odins boot script on the device/ or /in settings on the phone/?
Baseband is g900TUVU1ANCH
Build Num: AllianceROM_G900F_XXU1ANCF
If the "no network" issue can be solved with the current firmware that would be the most desirable solution but going through the flashing process may be a good idea for my learning process, and will help with future updates.
Do you think getting back to a stock rom would help me?
tHANKS AGAIN!:cyclops:
Model confirmed to be g900t
Sorry i didn't understand the "under the battery" thing. I was lost in software world. The sticker under the physical battery says SM-900T so i guess that confirms that it is a t-moble verison (and the baseband is therefore correct).
I will try to flash the T-Mobile stock image to the phone and see if that works.
Also i will try to flash a modem (after i work out which one i need).
Cheers, Yetti :cyclops:
Current status.
Flashed the stock T-Mobile firmware to the phone. No success.
Flashed new modem to the phone. No success.
Will go to the T-Mobile store tomorrow to see if they can help (I doubt it but i have to exhaust all the options).
Any more help would be appreciated...
cheers, yetti:cyclops:
By under the battery I mean like to take off the battery cover of the phone and pull the battery out and look at the sticker found there.
G900t.

Yep it says g900t (see above)
As per flashing a modem. I have heard that it is possible to flash any modem for any version of the s5 to the phone. Some work well and others not so much. I have tried 2 T-Mobile modems (baseband) the G900TU1ANCH and the G900TUVU1BNG3 with no success. Do you have any recommendations for a modem to try (or even a custom ROM that might help?)
Cheers,
Yetti :cyclops:
I know that you mentioned they refreshed the service for your number, but do they have the correct IMEI in the system for your account? Metro makes a big deal about that now and you can't just take your SIM from another phone and pop it in a new one and go like you can with pretty much every other service (Cricket is like this too now).
Hi all,
I have a UK GT - i 9300 locked to Orange and i have just been signed up to EE.
EE claim the phone is already unlocked.....it isn't. They failed to provide a SIM unlock code, so i went to a third party (computer shop) to get the code. They provided an unlock code, and an unfreeze code. They don't work. It just says "registration code unsuccessful" or something similar when i try to put it in upon booting up the device. The guy at the shop is now at a loose end and is happy to refund the unlock code fee, but says he cannot unlock the phone.
I have tried the codes that start with #1972.... to enter the hidden menus, i actually had to enter #0011# i think....regardless, that didn't work as under network options (or whatever it was called) i have no option to tell the phone to allow other sims.
I mention all of this because please believe me when i tell you there is not a simple solution to unlocking this phone....i have read pages and pages of forum advice and nothing works.
My very specific question is; can i root this network locked GT i9300 (UK version) which is currently running on 4.3....or not? It is the only possible solution i can see to save this phone from becoming a paperweight.
I can promise you that hours upon hours of research has not got me a sensible, definitive answer to this question.
Thanks guys. Much appreciated.
Paul
It doesn't matter if the phone is SIM-unlocked or not when you root it. If i can find a stock ROM for the i9300, or if it is 4.1.1 or 4.1.2 with the old bootloader, it is unlockable for free. http://forum.xda-developers.com/galaxy-s3/help-i9305/guide-sim-unlock-i9305-t3267901 this is the thread, tell me if you want me to find a stock ROM and i will try to make it zip-flashable.

Thank you for your reply.
Unfortunately after nobody responded yesterday i decided to flash the phone back to an Orange UK version of 4.0.4 and see if the Galaxsim unlock program worked from there. It has now given my phone the generic IMEI number 004999010640000 and Galasim is just saying "UNABLE TO READ NV DATA"
I've tried the method of changing the nv data bin files, and it doesn't work.
I have no backup of my original efs folder.
The bottom line here is that i have been going round in circles with this pile of sh1t service from Orange and EE, and codes that don't work for over a month now. I mean no offence by asking this bluntly, but can someone just give me a simple yes or no answer as to whether i need to buy a new phone or not?
It seems everyone has a theory on how to unlock this phone, and none of those theories actually work.
Currently phone is sat on
Android version - 4.0.4,
Product code - GT-I9300RWDORA
Original Product Code - ORA
IMEI NUMBER - 004999010640000/01
Sim Operator - EE(23433)
Registered Operator - @[email protected]
OS version - 4.0.4 (15)
Baseband - i9300BVLE4
Bootloader - I9300XXUGNB5
Patform - exynos4
LOCKED TO ORANGE.
Some simple instructions on how to fix this, or an honest answer as to if it is even possible would be GREATLY appreciated.
Thanks
Long post here sorry people,now guys I would really appreciate your input as I'm new to unlocking phones and flashing fw etc
I recently ordered a brand new handset that was sold to me as sim free unlocked uk version as I'm from the uk ,when I recieved the phone yesterday all seemed good and new and unused,so I went into software information in the phone to check if it was really a uk handset i expected to see XEU/XEU/XEU OR BTU/BTU/BTU like my other uk phones,but the service provider sw ver had weird csc codes I've never seen on a uk handset,its was
AUT/AUT/O2U now after doing some research the code on the right O2U is the original csc and cant be changed and O2U is o2 uk so the phone was a locked and branded o2 uk phone I guess?so I'm assuming the csc was originally O2U/O2U/O2U or maybe XEU/XEU/O2U? I may be wrong here ,but AUT/AUT from my small bit of research is a Switzerland unlocked firmware,so what has the seller sold me?
IS my phone a uk locked branded O2 handset,that the seller had unlocked so the phone would work with any sim card ,and did he flash swiss unlocked firmware?if so why?and how can I be sure what the original csc was for the first 2 codes?i know the 3rd code is O2U so if I wanted to get the phone back to the original state if I needed to send it in for warranty?or would a phone like this still be in warranty?
Now I did say this was going to be a long post I apologise guys.so anyway at this point the CSC codes are AUT/AUT/O2U then I put my uk ee sim card into the handset for the first time to check if the phone really is unlocked,after inserting the sim card a message came up saying please factory reset to make the sim work or something along those lines, but before I did that I went back into software information to see if the csc had changed and it had changed to AUT/XEU/O2U so this was weird,then I factory reset the phone, after the factory reset it prompted another factory reset so I clicked ok
Then after the reset was done I went back into software information and the csc had changed again for the 3rd time, this time to XEU/XEU/O2U and it's been on this ever since,do uk o2 phones have this csc?with XEU/XEU/O2U or would they be O2U/O2U/O2U? again I apologise for the long post but if you guys could tell me what my phone is and what has been done to it would be helpful,and is my warranty still intact if the csc has changed automatically by me inserting my sim card?and if I wanted to revert the phone back to how it was before it was unlocked what would the csc be and how easy is it to revert it back to the 3 original csc what ever they may have been,
Ok guys I probably should have just called samung before making this thread,but I just called them and gave them the imei number and they said it's a uk 02 locked phone that is unlocked now for any sim as I'm using my ee sim.so I dont know why the csc said AUT/AUT/O2U .them changed to AUT/XEU/O2U then changed to XEU/XEU/O2U
But if I wanted to turn my phone back into a locked o2 phone again not that I would probbly need to do this but would the phone have been branded or non branded o2 phone.and what would the csc be and would that change automatically from XEU/XEU/O2U to something else if I were to flash android 10 firmware for a uk o2 phone using Odin would that change the csc back to what it was originally before I recieved the phone?or would I have to do something else to get the original csc back?
I think the O2 carrier firmware was changed to unlocked/unbranded
If I wanted to take it back to o2 like it was originally how would I do that? Could I just flash this 02 android 10 fimwhere using odin and that will change the csc back to whatever it was originally will this O2 file make my phone 02and locked o2 again?and would I need an o2 sim card to make the csc change back to the original csc .or will it auto change after flashing the o2 firmware?
