[Q] Is my phone software unlocked(versus factory) Please helpp? - Galaxy S III Q&A, Help & Troubleshooting

Hello,
I will have to give background info on this before anyone can help so bear with me please :.
I live in Pakistan and I bought a i9300 directly from samsung. In the beginning of the six months i owned the phone, I never rooted or put custom ROMs on it. Then unfortunately I got SDS. I gave my phone to a local repair shop (non samsung, but highly reliable, I bought the phone from there) who switched the motherboard on the phone. After I got it, I rooted it and started installing custom ROMs on it. First it was cyanogenMod, then Paranoid Android and Supernexus +AOKP and others. Everything worked fine. Then I installed Omega ROM (Samsung based ROM which changes the modem). Everything went fine, but I was unable to connect to my network (No texts, calls, data connectivity). It detected my network(Ufone) but was unable to register on it when I manually tried to. I mega-wiped my phone, cleared cache and factory reset and did everything. Alternatively, the following steps I also tried.
1)Checked if my IMEI is intact. It was. (I have EFS backups too)
2)Checked if my serial # is different. It is still the same (No need for Ariza Patch)
3)Checked if my SIM works. It does on different phones.
4)Checked my APN settings. They were fine. I even manually changed them to match the carriers
5)Changed my CSC settings (using the playstore app). Still doesnt work.
6)Checked different modems from the appropiate thread (I have tried Europe Unbranded, Middle East, Egypt and many others)
7)Restored nandroid backup of original stock 4.1.2 Sammy ROM, still not connectivity.
8)Flashed using ODIN, the stock 4.1.2 ROM for my country (Using SAM mobile). Still no connectivity.
9) Matched my RIL with my baseband (using the GetRIL app), still didnt work.
Stock Samsung 4.1.2 ROM details before OMEGA flash in which everything worked:
AP: I9300XXEMA2
CP: I9300XXELLA
CSC: I9300OJVEMA1
This has happened to me the 5th time now (Phone is currently at the repair shop) and I have sequentially tried every one of the steps I have mentioned. I called up the repair shop and they said that I can come tomorrow and pick it up, all they have left to do is "SIM UNLOCK "the phone. That confused me a lot. I will go tomorrow and ask them details as to what they meant by that. So my question is basically this:
1) Is it possible that the motherboard they put into my phone is from a software-unlocked phone not a hardware unlocked? (Is the 'unlock' on the motherboard of the phone)
2) Is there a way to find out if my phone is software or factory unlocked?
P.S. Every single time I hand in my phone, I obviously unroot it and install stock on it (regardless of the fact that it doesnt connect to the network). But every single time I get my phone back, its ALWAYS ROOTED.. I even asked the technical team guy and he had no idea what I was talking about (repairmen here dont have that much of knowledge, they tend to follow guides online, thats it). So could it be that my connectivity issue is just because its software unlocked and not hardware?
Thank you!

Anyone?

Not a genuine service centre then .

all correct for network suggests a hardware fault .

But it's not a hardware fault? I mean whatever they do, they have to root the phone to be able to do it. Any idea what settings or configuration they might have changed using root for it to connect which I haven't already tried?

[Q] not registered on network. Galaxy 2

Hi.
I have a big problem with my G2, and have tried many things.
It all started 2 weeks ago. I lost connection to my network.
I tried many things, and ended up giving it to a repair shop, in China, as I was there shortly. They put a new firmware into the phone, and a chinese SIM card worked.
I found an english version of the firmware, and asked them to update with that version, No problem. Everything worked well...but when I arrived back to Denmark, same problem. Not registered on the network.
Now I have tried many things, as Kies could not recognize the firmware version. I burned a 2.35 version into the phone with Odin, and Kies regocnized the version, and now updated to 4.03. Great, but ... I have the same problem. APN settings acc to my network provider. Oister 3 in Denmark.
I really have no idea what to do anymore. And I cant send it in for repair, as the flash counter says 10 times.
Is ther someone here, with a very deep knowledge in Logs etc, as I can send Logs if I am explained what to do.
The short time the phone worked, did I really love it.
And also the chinese SIM can not connect from Denmark.
I would prefer all Logs etc in private email, but if we solve it, I will poste solutions and results here.
Best of regrads
Morten
As for the counter, install and run triangleaway - it can be found in the SGSII section of XDA.
Check that the sim card works (try it on another phone) and borrow another sim card (on the same network). It is amazing how many problems like this are due to a damaged sim card or just not connecting correctly. I had a friend who took the sim card out to flash their Samsung Galaxy 3 and put in the sim card wrongly and couldn't make a call.
Can you copy your contacts to or create one in the sim card?
I doubt that it is a problem with the EFS folder, ie no IMEI number because it was fixed with a china sim, but it may be. Is the IMEI number you get from dialing *#06# 004999010640000 or different from the label under the battery? If so then you have a EFS folder problem. There is an app that may fix it - it requires root - * HERE *
Mobile network
Hi
Thanks for the reply.
A:
I can make, copy, edit etc contact directly at the simcard in the phone, and also copy, edit etc from Kies to the Sim card. And yes. It is the simcard I can do those things at. Double checked that it was somcard and not the phone memory
B:
Double checked the IMEI number again.
Label phone same as *#06#
Further information:
In the first day, I tried many many things to get the phone working.
I searched the internet a lot, and I found some kind of help. Like with IMEI check, I should type a code like *#xxxx# or *xxxx* Stupid as I was, I did not write down the code, and also did not safe the page on the internet, so I have no idea what code I wrote. I am sure it was something regarding Mobile network or CSC.
Reg Triangle away.
My phone is no longer rooted, as I try to have it in original mode, so its ready to send to repair, if needed. Triangleaway needs the phone to be routed, right ?
And will that not require an unsafe kernel ?
After resetting, then I suppose I need to install an original kernel again, and will that not make the counter go to 1 ?
Any other ideas ?
Regards
Morten
can you be little clear....
no network or no data (internet) on your current network
1: do you have a locked phone or unlocked. [carrier locked when new]
2: no network will be no signals at all, no phone call....
3: no data will be you cant browse, send receve emails
4: counter can be fixed easy as now your on ics
Hi,
I got the same problem but different scenario

1. my phone is unlocked(international).
2. signal show full, but no phone call
3. I don't use data, but wifi, and no problem with wifi.
Well, this : not registered on network only happen if phone idle for more than 3hrs, meaning phone just work normally if I don't let it idle for long time. This very frustrating as every morning after wake up I have to switch between airplane mode for phone working again.
Greatly appreciated for your help
Thanks in advance
P/s: currently on Slim rom(cm9). But have tried almost all custom rom found in xda, problem still exist. Even try to change CSC to my current country( Thailand) on stock DL7( included Thailand region), no luck. APN setting also change to default network provider.
Mobile network problem
Hi.
Please see my answers below
1: do you have a locked phone or unlocked. [carrier locked when new]
The phone worked before, and was not locked, but as I send a command to the phone, could I have locked it ? How can I check that ? And it does not give me any warning when I start the phone up.
When I try to make a call, it right away says: Dialling ...Call ended.
2: no network will be no signals at all, no phone call....
No mobile network. It is ONLY a problem with phone calls and reciving calls.
I have plenty of signal
3: no data will be you cant browse, send receve emails
Data is right now not working, WiFi works.
I cant get correct APN settings, as my provider sends this as system configuration to the phone, but cant recive it.
3A: My provided is named 3 Oister, and normally this provider is listed under Network operators. On this phone it is NOT listed. 3 Oister is using network of 3, and only network of 3 is listed.
If I pull down the menu from the topbar on the phone, it actually says 3 Oister, but 3 Oister is not listed under Network Operators.
On my other SG2, 3 Oister is listed in Topbar and under Network Operators.
I bought a new SG2 as well, and we are 2 persons using SG2 here.
4: counter can be fixed easy as now your on ics
How ? Can I do that without rooting and install different firmware ?
I do run ICS ver 4.03, updated by Kies.
In worst case, I will send the phone in for repair, but for sure, needs the counter reset.
Regards
Morten
Put a new firmware in the phone then probably wrong modem and CSC for your location .
Chinese sim unlikely to work 4000 miles away but that is easy to swap sim .
Rom counter for ICS use the search tool for the relevant post .

Hi
Please find answers below:

As my counter says 10, you can see, I have tried this several times, and its also written in my first post.
Please send the code for check of CSC and changing CSC. As I remember it is set to be NEE.
Chinese sim unlikely to work 4000 miles away but that is easy to swap sim .
Chinese SIM works all over the world, as long as Roaming is allowed. And it works in the other phone. Now I have the Denmark SIM in, and same problem. Yes, I did close down the phone, changed SIM and started the phone again. Exactly SAME problem.
Rom counter for ICS use the search tool for the relevant post .
Would be nice to have the info written here instead.

Mobile network problem
Hi again
Followed the guide very detailed
3: using cwm format system, cache, data, sdcard [system is a must]
Wiped all data in System and also Wiped Cache, using:
Root the Samsung Galaxy S2 GT-I9100 running XXLPQ firmware and install ClockworkMod Recovery: CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5.tar
Done with Super User Granted.
4: remove battery / insert back goto download mode
Done
5: flash the ROM you downloded using odin, after restart dont do any restores
Flashed with Odin 1.85 in PDA: I9100XXLPQ_I9100HTDLP3_I9100NELP2_HOME.tar.md5
6: wait for few minutes now dial this *2767*3855# [important]
Done. Phone shows Factory Reset in big letters
dont restore any backups including titanium stuff.
Nothing restored.
Booted up, and automatic installed APK's
Same problem.
Only difference is that now the counter says 11 counts
But thanks for a detailed and well told possibility.
As I see it, the problem is connected to the standard the phone connects to the Mobile grid. As I told earlier, I made a stupid thing. I send a command with *#xxxx* in the phone, and I cant remember what code, and I did not save the page on the internet. I really think the problem is about a standard. That the phone is setup to a standard that the 3G net is not using in Denmark.
I can dump logs etc, if anyone can help. But I need to know how.
Regards
Morten
buddy your problem was.... network right? is it working now?
forget counter it will be fixed....later using triangle away with ics bootloader
---------- Post added at 12:06 AM ---------- Previous post was at 12:01 AM ----------
if your phone now works fine with calls send and recieve, manually add the apn to get 3G.
Mobile network problem
Hi
Nope. Did not solve the problem.
Just ran Triangle away, and moved the Firmware: I9100XXLPQ_I9100HTDLP3_I9100NELP2_HOME.tar.md5 to the SD card.
Will try now to install it by CWM
And then I give up. Will try to send it for repair ..... really a shame, as I really would have liked to solve it here
Cheers

Mobile network problem
Hi Buddy
It finds a lot of Networks, but cant connect to any of them
3 networks with 3G and 4 with 2 G
But not the Mobile network I need to connect to> Oister 3
My other SG2 finds that network without any problem
Cheers
Morten
I had the same problem too. At first I tought it was a rom issue, but it wasn't actually. I turned my phone off and removed and placed back my sim card and it worked.
Mobile network problem
Finished programming original firmware using CMW as source for Odin, after counter was reset to 0, and the pnone status is the same as before, but counter is 0.
So will try to send it in for repair.
Thanks to u all.
And SIM card has been removed several times, even tried with a different.
No luck at all
Cheers, and thanks again
Morten
Did you ever get to the bottom of this?
I've been using my phone in Brazil and now i'm in the UK, it's doing exactly as you describe.

How would you go about checking these?

Compare the IMEI that displays when you type *#06# to the IMEI printed on the label under your battery. They should be the same.
For your own sake, do NOT post what the IMEI under the battery actually is, whether it's the same as what's displayed when you dial *#06# or not.
As for checking IMEI blocking by the carrier, that should be obvious. Call your carrier.

[Q] Mobile Network Not Available - Samsung Galaxy S2

Hey guys,
This is my first post here so please be nice I will try be as informative as I can!
Last week my aunt got a Samsung Galaxy S2 as an upgrade after my recommendation. She loved the look of things and liked how she could access Youtube and Facebook but then she got locked out of her phone completely and couldn't get back in because she didn't know her Gmail account.
After a bit of research I found out that I should do 'Hard Reset' and all should be back to normal afterwards, I did so and everything looked okay.
After giving the phone back to her my aunt said she no longer wanted it and gave it to me because it was too 'complicated'. Obviously I was overjoyed as my current phone does not even compare to this beast!
I put in my Orange sim, (hers was Orange too) turned on the Wi-Fi to update all the apps not even noticing that the 3g icon wasn't on. I could see the phone had some signal so I thought everything was okay. It was only when I tried to call my dad of the phone that I realised something was wrong. It said 'Mobile Network not Available'.
I have found many threads about 'rooting' or IMEI but I don't understand what they mean as I am a newbie in all of this.
I would send the phone for repair but it does not have insurance so that's a no go. The phone came unlocked too so I don't understand why it's doing this. The sim I put in works on my old phone so I'm pretty sure there's nothing wrong with it.
What should I do?
Looking forward to your replies
See * HERE *
Remove your battery and your sum card.
Wait 10 seconds put them back in and reboot.
If problem still exists go to
settings > wireless and networks > mobile networks. Select your carrier network.
Sent from my GT-I9100 using XDA
Thank you for your replies samgalaxys2 and dred_up, I appreciate it!
I tried doing what you said samgalaxys2 but nothing's changed, I tried doing it myself before but no luck
In reply to your questions on the other thread I can confirm that my sim works as it works on my old phone. I can also create contacts on the sim too.
I don't know what the EFS folder is but when I dial that number you said (*#06# ) I can also confirm that the IMEI is the same number shown in my settings and underneath the battery.
What should I do?
Wiska.
The fault = put your sim in the phone then not working .
First step has to be to get a new sim .
That would be followed by either a return to a service centre or via XDA a flash of new stock firmware .

Have you tried the Access Point Names in the network settings, mine changed it's self after flashing a new rom.
Hello JJEgan, I have tried various working sim cards and it doesn't make a difference, I even tried a brand new T-Mobile sim. In the 'About Phone' section I can clearly see the Sim's name but it always says Out Of Service underneath.
I have tried that too s.d.oconnor, at times it doesn't work and when it does it says something like 'Network Updated' but nothing changes.
What do you guys mean by 'Flash of new Stock Firmware' & 'Flashing new Rom'
Sorry for the amount of questions guys, I have never experienced something like this before

Hmm okay,
I followed the thread and had to do it at-least 3 times before I could do it 'correctly'
I managed to get Ice Cream Sandwich OS on the phone and although I could now use the sims internet I can't use it to call or access my voicemail.
What can I do to fix this?
If I have to download a new rom could you copy the link because I think that maybe that's where I went wrong?
I am sorry but I tried my best as it is my first time doing all of this.
I think the Rom should be an XX as the phone and myself are in England plus my network is Orange
Wiska.
You can use the Dutch firmware XEN without problems...
Also is your fone a i9100P (NFC) or standard i9100?
Or take fone into Orange or a Samsung repair centre to have it checked out.
Hmm do you recommend I Flash it again and get XEN?
Do you think they'll repair it even though it has been flashed? I've got ICSandwich on it and I don't think Orange has released it yet lol
I tried to change the APN but nothing is happening

If it was a Orange (UK) branded phone, then first download, install and run Triange_away app. This will reset the custom rom flashing counter and take away any triangle at boot up (if present).
Next you need to download and flash the BVKJ4 rom from * HERE * - it is the latest official Orange UK ROM. It will wipe the phone to factory setting and you will loose root. It may solve your problem, but if it doesn't it will put your phone back to valid warranty for the service centre.
Sorry for the late reply, the amount of work college gave us yesterday was just too much!
Thank you for the link fred_up but the links are dead
Thank you for trying to help though, I really appreciate it mate!
Anyone know what I should do?
Search for the stock rom you're after on Samfirmware.com.
Edit to add - Make a note of the rom details from Intra's thread (the one you were linked to where the links don't work), that will make searching Samfirmware easier.
Thank you MistahBungle!
I am downloading what looks to be the firmware I need right now so fingers crossed it works!
Many thanks for the help mate! I will keep you updated if it works or not
I tried the latest Orange one but that didn't do anything, I then tried using the Carphone Warehouse one and although the 3G internet stuff works I can't call or text!
This is so annoying lol, any advice?
The phone isn't locked or anything as my aunt gave it to me, what can be the problem?

[Q] Need help. GT-i9300 network problems + sn = 00000000000

Hi All,
I have accidentially bought Galaxy S3 GT-i9300 in China. Device came with Hong Kong 4.0.4 firmware. Unfortunatelly i could not fully test it because i didn`t have a micro-sim. It is international version called I9300GSMH.
I returned home, made a backup of EFS with EFS Pro and flashed 4.1.2 Poland into my new toy.
After that i immediately got several problems:
1) IMEI is OK and legal, but SN = 00000000000. That means no network and no phone calls. Fixed quickly with "special modem", but not sure if it was the best way.
Is it possible to repair SN if i know it? Does it make any sense by the way?
2) GPS is not working at all. GPS Tool doesn`t see any satellite. Neither GPS no Glonass.
Have no idea how to fix it and why this sh,,t happened.
3) Wi-Fi range = 30 cm. My router is Dlink DIR655. Other Samsung devices work with it up to 15 meters around. This one - 30cm. Tried to change settings, apply fix - no result. My S3 can see all wireless networks around, even located on the different floor of the building... but it can`t connect to any of them with "passwor wrong" message. Put it right on the router and problem disappers. WTF???
My S3 came from Hong Kong, but it doesn`t accept China/HK firmwares. Odin stops on flashing the modem stage. Actually, for some reason, it can`t flash China/HK modems. My S3 accepts any of european FW/Modem, but not chinese, where it actually came from.
Now some surgery. /EFS and /Factory folders are different (how could that be?) Files NV_data.bin and NV_data.md5 are different in those folders. Actually approx 300 bytes are different.
NV_data.bin and .NV_data.bak are totally different and they have different dates of creation.
That is it. Have no idea what to do with this phone. It works as a phone with the patched modem, but no WIFI, no GPS, etc.
I will appreciate any help on this case.
Thank you in advance.

Thanks, but it is already done. My S3 doesn`t work with GSM network without Ariza patch. "Special modem" i meant Ariza patch for modem. That is the only way i know to make SN=00000000000 device work with GSM.
Any ideas why i`m having GPS and Wi-Fi problems? May be HongKong phone has slightly different hardware which is not 100% compatible with European firmwares?
Sounds like a convincing looking fake or a store demo unit etc.
Nothing is going to help, if it was a workable fake your going to need the custom firmware, the criminals used originally to build it.
Can you post a screen shot of the system info and pics of the actual phone?
Personally I'd just take it to a mobile repair shop to get it looked at and to get a proper answer.

I don`t think it is fake because system information looks like genuine samsung except sn=00000000000. also i can upload samsung firmware to it and it works except GPS and Wi-Fi. Under the battery there is a label containing Model = GT-I9300, real IMEI and SN.
Another question is modem. Telephone came from HK or China. I can flash it with HK firmware to return it to original state, but modem remains XX - europe. When i flash only chinese modem Odin fails with "bootloader blocked modem update" or something like that.
Smells fake .

Why do you think it is fake? Fake phone has different firmware and not compatible with Samsung.
I have checked deviceinfo as well. It is genuine Samsung...
Can someone share deviceinfo from the International GT-i9300 ? I want to compare, may be some IC chips are different and i am simply using incompatible firmware...

2) GPS is not working at all. GPS Tool doesn`t see any satellite. Neither GPS no Glonass.
Have no idea how to fix it and why this sh,,t happened.
3) Wi-Fi range = 30 cm. My router is Dlink DIR655. Other Samsung devices work with it up to 15 meters around. This one - 30cm. Tried to change settings, apply fix - no result. My S3 can see all wireless networks around, even located on the different floor of the building... but it can`t connect to any of them with "passwor wrong" message. Put it right on the router and problem disappers. WTF???
My S3 came from Hong Kong, but it doesn`t accept China/HK firmwares. Odin stops on flashing the modem stage. Actually, for some reason, it can`t flash China/HK modems. My S3 accepts any of european FW/Modem, but not chinese, where it actually came from.
Now some surgery. /EFS and /Factory folders are different (how could that be?) Files NV_data.bin and NV_data.md5 are different in those folders. Actually approx 300 bytes are different.
NV_data.bin and .NV_data.bak are totally different and they have different dates of creation.
That is it. Have no idea what to do with this phone. It works as a phone with the patched modem, but no WIFI, no GPS, etc.
I will appreciate any help on this case.
Thank you in advance.

Exactly same situation in Argentina.
I bought a SGS3 and after full charge battery and backup EFS I flash the Poland 4.1.2. After that i can´t connect to GSM network and my serial numer is 00000000000
Is not a fake. I bought from a recognized operator.
Then I flash an ICS 4.0.4 ARO (ARO = Samsung official roms for Argentina)
Now I looking for the Ariza solution, but I fear to have the same problems descripted here, cause I have the same facts.
So ¿Any questions to this post answers?
Thanks people, for that who live away from big cities is impossible go to a technical service.
Update. I`ve also got i9100 aka Galaxy S2. After official (no grey market, no sim-unlocks, no root, no odin, etc) update via Kies it shows same SN=00000000000, but everything is OK. GSM, 3G, WiFi, Bt, Gps - all parts work as they should work without any problems or applying any patches!!! That means problem is not in SN=00000000000. This zero SN is probably just a sign of the different problem.
same problem

Thanks, but it is already done. My S3 doesn`t work with GSM network without Ariza patch. "Special modem" i meant Ariza patch for modem. That is the only way i know to make SN=00000000000 device work with GSM.
Any ideas why i`m having GPS and Wi-Fi problems? May be HongKong phone has slightly different hardware which is not 100% compatible with European firmwares?

No IMEI = return to seller possible stolen phone . Take to service centre .
Modem does not fix IMEI .
IMEI restore is only by restoring your backed up EFS folder .

If your phone has only empty/broken IMEI. You may send it to any service center. It is very easy to reprogram EFS and repair IMEI if you have original IMEI on the phone label.
In my case nothing worked but IMEI was correct and here is step by step instruction )
Step 1. Find working 2nd hand 9300 motherboard ($130 in my country).
Step 2. Replace motherboard.
Step 3. Ta-da.

[Q] can't call

hi there!
Ive read all I could and despite coming across several similar problems, haven't found an answer (so if anyone has an idea, plz help!)
I'll try to be as concise as possible:
I have a message that says: not registered on network
I have a China Unicom galaxy S3 (international model, gt-i9300) not copy, original version, bought from service provider store, running forever on android 4.0.4 (no updates available, via kies, or software update whatsoever)
As you know, because it was bought in China, it's blocked from factory settings (no svoice, google play, among others and of course a reduced overall functionality and an alarmingly high used of RAM despite of every app being closed) and even you can download most apps, they're in Chinese and they're different and not completely working versions of them (i.e. fb, skype,...)
Read and read, until managed to do rooting via heimdall (only have mac available), once installed SU, managed to download and install google play, but it kept on crashing, along a previously (VPN only) functioning fb app, and twitter.
After a while of more research I came across odin mobile, and by downloading an international ROM from Hong Kong via Sammobile, managed to install 4.1.2 from HK (I9300OZSEMC1). Despite the now no restriction phone i had, i came across a problem: cannot call or message or use mobile data, only with a message that says " not registered on network"
I did check the sim card, and selected the network manually, without success.
I checked the AP, CP and CSC and they were unknown.
After much frustration i remember i had a backup if the original carrier, and after re-rooting, managed to get back to the super blocked version of it, bu t the problem remained: not registered on network.
I checked again the ap, cs and csc and now are back to factory default (just like they were before all this odyssey began).
I changed the sim card to my gf's iphone and it works there, just not on the galaxy....
I repeated the above two times more, using roms from HK, Taiwan and UK..... same problem, even when going back.
Any ideas? I'm quite desperate now
thanks!!!
Is your IMEI the same as under the battery .
If not restore your backed up EFS folder.
No backup = service centre .
Do you have the correct modem and CSC for your network .

yes, imei is the same
before doing all the process, i verified and saved screen captures of how it was before and after, both pictures coincide, but still nothing...
(what is EFS folder? , i've done this with little knowledge on the topic, so i've no idea what's that ^^"
I guess service centre might help, but well, since this is China... i expect the worst.

I'm assuming you may have changed the modem during the flashing of the HK fw, try finding a Chinese Modem and flashing that. TBH this is why people tell you to read and read again before rooting and flashing custom roms.

[Q] Phone settings say g900f but odin says g900t

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).
