In need of some assistance:I9300GSMH - Galaxy S III Q&A, Help & Troubleshooting

Hello, First post here on Xda, Nice to meet you all.
I'm looking for some serious help with my new samsung galaxy S3GSMH International version.
Long story short, My girlfriend lives in germany, While on holiday there I purchased a samsung galaxy s3i9300 and was told it will work in any region any network due to being factory unlocked.
In germany I was using a sim card from VIVA mobile or something of the like and it worked fine.
After I returned home, I switched in my UK Vodafone sim card, A message then popped up saying, Please select sim service:vodafone UK/Vodafone UK prepaid.
So I chose Vodafone UK and clicked on OK, I thought everything was fine untill i tried to make a call and got, Not registered on network.
Now I have searched for days in all types of threads to get this fixed, I have tried flashing stock firmware with odin/emergency recovery Via Kies/Flashing modems/flashing patched modems/patched kernals/Ariza patch/Ariza patch Jb.
My Imei is fine and matches under the battery, The S/N also matches under the battery.
So I just don't understand it, If it asked me to choose which sim service surely that means it has some type of connection with the network? I have full signal bars too.
Is there anything else i need to do to get this working? Because I am at a loss, And I obviously can't take it back due to the shop being in germany
Any help or input is extremely appreciated!

[SOLVED] Cannot use GSM radio - help needed!

I have since discovered that my IMEI has been blocked. This phone was bought off eBay in January but apparently the block was only placed on August 7th. I'm gutted, I'm really hoping this can be resolved or that I am covered by insurance.
--------------------------------------------------------------------
Hi everyone,
I'd greatly appreciate any help anyone can give me. Here is what happened:
About 2 weeks ago I upgraded radio from 1.38 to 1.50, which worked and everything was fine.
Last week I went on holiday to a little place on the beach, where signal has normally been a problem. Not so this time, I had plenty of signal and was talking and texting fine.
On Tuesday it worked all morning and then in the afternoon the signal dropped off and it said "no service". I cycled the phone radio a few times and rebooted the phone, all to no avail. I concluded that the local cell tower had a fault and that I wasn't in range of another.
On Wednesday we took a trip and, as I expected, a few miles down the road my phone picked up signal again, consistent with the faulty cell tower hypothesis. I recieved a load of texts that had been waiting for me, made a few calls and everything was fine. When we got back to where we were staying, the signal held - I presumed the fault had been fixed.
Later that evening the signal dropped out again as before. I assumed that perhaps the fault hadn't been sufficiently fixed in the cell tower, so while annoying I presumed when I got to a different area the signal would come back like it did before.
However, it didn't. We came home on Friday and it hasn't picked up a signal, just says "no service". If I manually search for networks it finds O2 (as well as all the others) and I can select it, but it still says "no service".
I plugged in a T-Mobile sim, and it found signal immediately, BUT I cannot send/recieve calls or texts, people calling me hear a strange problem about it being unable to connect their call, and text message delivery reports give the same (not the message that one gets if the phone is switched off) - so it is obviously on the network but something is stopping it using the network - when I try and make a call I instantly get those four beeps which indicate the call has ended.
I then phoned O2 and said I think my SIM is dead, and they agreed and are sending me a new one. However, I then tried my old O2 sim again and got a brief signal, but still the same problem as the T-Mo sim - cannot send/recieve calls/texts/anything.
My O2 sim now says no service, although I have tried it in another phone and it works fine.
Since then I have re-flashed 1.38, hard reset the OS (Sleuth's v3) and flashed the O2 WM6 official rom with 1.47, all making no difference. I've tried forcing 2G and 3G and particular frequencies (it usually says it cannot apply these band settings, but after several reboots I sometimes manage to change it).
So, in summary:
Signal is very intermittent and usually says "no service".
Even when I do have signal, I cannot send/recieve calls/texts.
My O2 sim definitely works.
I have tried radios 1.50, 1.38 and 1.47 to no avail.
I have hard reset the ROM (Sleuth's v3) and flashed the O2 official ROM to no avail.
Desperate for help! Many thanks
I have also cleaned the SIM, SIM contacts in the phone, and checked that I can access the SIM card from the phone, and I can get the phone's IMEI etc so at least part of the radio seems to be working, and as mentioned before the SIM definitely works.
Thanks
Update:
I have tried Orange post-pay and Orange pre-pay sims and they both work fine, so it doesn't appear to be my phone that has broken.
However, my original O2 sim continues to work in another Nokia phone, suggesting that the sim isn't broken.
It may just be the pairing of that sim with my phone, which is the only thing I can think of. Does the Hermes apply sim "profiles" to sims which are inserted? Have I messed up the profile associated with that sim? My new O2 sim should come next week so we will see if that one works.
Also, the error messages of the text delivery reports sent to my phone while my O2 sim was in it say "Interworking Not Available" (this is from an Orange phone). Any idea what that means?
Thanks to anyone who can help.

Shot in the dark here: how did you get your Hermes? Could it be blacklisted from O2 - i.e. could it be stolen from an O2 subscriber. (I would assume by the person you got it from, I am not accusng you of anything!)
Hi Todd,
Thanks for your reply. It's not something I'd thought of but it could fit the scenario. I got the phone off eBay back in January and had no problems with it until now. It's actually a T-Mobile branded one, (i.e. the MDA) rather than the XDA Trion. When I phoned O2 to ask if my account had been blocked and to get a new sim the person I spoke to said there was nothing to indicate that my account would have been blocked, which would presumably include any blocked IMEIs that were listed there. Also, if the phone had been blocked after being listed stolen it would have been blocked on all networks wouldn't it? If my new sim doesn't work I will phone O2 and ask them if my IMEI is blocked, so thanks for your suggestion.
As updated in the first message, my IMEI has been blocked, causing all the problems. The reason the Orange sims worked must be because the block hasn't propagated to the Orange network yet.
Hey i discovered i had the same problem today aswell i bourght the phone of Ebay for the first day it was working then next day i upgraded to WM6 and it stop working i did some research on why it stop working and here it was
Orange & O2:
If you place an active orange or
O2 sim into a blacklisted handset you
phone will not show any signal strength
at all! If the handset is a Nokia then a
"SIM card registration failed" message
will also be displayed. If your handset is an
Ericsson then an "Invalid Mobile" message
will be displayed. For most other manufacturers
the handset will simply show no signal!
Vodafone & T-Mobile
If you place an active Vodafone or T-Mobile sim into a blacklisted handset, the phone will appear to function perfectly UNTIL you try to make an outgoing call. When you try to call out from the handset you will hear a sequence of beeps and then the call will be dropped!!
wow nice story man , it seemed like a movie or something
anyway before i finish it i expected that your problem is that the phone IMEI is blacklisted . since its working with orange and other sims . its usually normal to get signal but u wont be able to make or recieve phone calls .
good luck .

SIMs not finding phone network?

Hi all...
I recently picked up a cheap UK Orange SPV M600 (G4 Model) from eBay, and I've been able to follow all the instructions on here to try a few different ROMs already
The problem I have is that everything works perfectly, except for the phone!
It was (obviously) originally on Orange, but I used LokiWiz to get the SIM unlock code, and then entered that successfully with an O2 SIM in the phone... but now it won't work with any SIM apart from a Greek Vodafone one which I had lying around.
I've tried various Orange and O2 SIMS, and none of them work apart from the Greek Vodafone one
All the SIMs I've tried are recognised by the SIM Manager tool, and I can view and edit the sim contacts etc... but all I get for the phone signal is "searching...", and it never locks on to O2 or Orange... only Vodafone.
Any ideas or suggestions please?
[edit]Just realised that I didn't say i HAVE already tried all of the different radio roms available on here, and none make any difference
Another question?
OK - no replies to my first post, so I guess nobody has any suggestions, but I've done a little more reading myself and I now wonder if the M600 has been previously reported as stolen or lost and is now network blocked by it's IMEI??
As far as I can tell, O2 and Orange will refuse to connect an IMEI blocked phone to the network at all, while Vodafone will allow it to connect, but won't allow you to make or receive calls... which does seem to be what's happening with my old Greek vodafone SIM installed.
Can anyone confirm if my understanding of IMEI blocking is correct, and can anyone tell me how I can find out if a specific IMEI is on the UK blocked list please?
As I said, I bought this through eBay recently, so maybe I could still get my money back if it's been stolen and then sold on through eBay, but I guess I'd need to know that's definitely what's happened before I could try that, so ANY help would be much appreciated.
Bad netiquette to reply to my own OP I know, but I thought that would be better than just editing my original... sorry if anyone gets annoyed at that.

I have the same problem, today i rang samsung uk to confirm the phone was good for uk and they did confirm it was a uk phone and they suggested that i ring various network providers to check the imei against their database, after spending a long time talking to various support teams in "lost or stolen " i ended up with all the networks saying phone was not known on their network as lost or barred so now i am in the same boat as you, mine has jb 412 installed.

[Q] Modem problem perhaps?

The more I read the more confused I get. I have had a thread going on Sammobile that got quite long but did not lead to a solution.
History.
This phone is a replacement phone from an insurance company. The original phone was Tmobile UK contract and locked that way. It was replaced by the insurance company as the first one had sudden death.
This replacement phone stopped charging or being recognised on the USB and went back to Samsung, they declared "liquid ingress" and refused to do anything. It then went "somewhere" for god knows what and was returned and I was asked to have a look at it.
Originally it had 4.04 on and was never updated from that, on return it had 4.3 on and doesn't work (emergency calls only).
I ripped it to bits and mended the USB problems then started looking into why the phone doesn't work. Kies reports that the phone is SFR, not TMU. As this phone was Tmobile and locked to them I can only assume that the insurance company bought some cheap and put the Tmobile software on which meant that when the firmware was updated it locked to SFR. (brain fading about now)
I rolled back the software with Tmobile software but (of course) this leads to a knackered IMEI. I have tried the latest SFR software expecting that even if it is locked to SFR I should get an unlock request box when I stick another SIM in, I don't get that option and even if I did I couldn't get an unlock code from SFR as it isn't one of their phones. I have tried using Kies to update using the serial from a couple of phones that are identical to this one, one Tmobile (EE) and one Orange (EE) expecting that something should work but all to no avail, no matter what SIM I stick in or what image I put on I get the same result every time. The IMEI is correct if I have a 4.3 image on and in the network list it finds all the mobile providers fine and it does say connected to network if I select any of them, the display on the notification bar shows it with signal.
I can root it and stick CWM on though currently it isn't that way. I can get SSH once that's done though it does seem somewhat flaky on SSH.
So, in a nutshell the phone doesn't bleeding work and I'm getting close to launching it out of the window. The only thing stopping me is that I know that someone here knows how to get it going.
So let me know what needs to posted in terms of numbers or screenshots and I'll stick them up here.
Thanks for not dying of boredom reading that epic.

Check what on the CSC and APN and how?
I tried the second link in your post, I now have no IMEI at all.
OK did it again. Updated using Kies "Firmware upgrade and initialisation" to put SFR 4.3 on.
Used Kies to load I9300XXELLA Tmobile 4.12 from SamMobile.
Used the modded modem in your second link.
Happily connected to Orange and working.
Thanks for the input.
I am sure I have done all that before and the first time I tried it this evening it lost my IMEI but the second time it all worked fine. End of an epic. Back to normal life now and this phone is never getting an update of any sort ever again, month of my life down the pan never to return and at 58 years old there aren't that many months left.

[Q] Gear S =Phone Not Allowed MM#6

Hello Everyone.
I am stumped on this issue. There doesn't seem to be any solutions for me. Here is What's happening, then I will tell you what I know..
Originally an ATT watch. SM-R750A
The IMEI is perfect. Not black listed at all. (Verified with ATT,SAMSUNG, and TMOBILE)
It is unlocked by ATT - I received the code and used it with the Tmobile Sim card inside when prompted. Success.
ATT Sim cards work perfectly,and with 4G!! When my Tmobile Sim goes in there, it only allows Emergency calls.
The APN settings are automatically populated. Verified to be correct with Tmobile. Basically, everything is fine on their end..
I am getting the run around from all 3 sources. They point the finger at each other.
Example:
Tmobile :"ATT did not unlock it completely, call them and ask for it to be fully unlocked."
ATT: "Once we gave you the code, our hands are tied. Call samsung, they may be able to complete your request.."
Samsung: "This is a service/network issue. Contact who ever your sim card has service with.."
Please help me, I have tried everything I can think of.
I researched all over the internet.. There are no working solutions anywhere!!!
I even Oden flashed the Official Firmware from ATT to Tmobile, so now my Model # is SM-R750T. I get the same errors. Att sim cards still work perfectly.
:crying:
I added photos of a menu I found on the device.. I dont know what this means..
I can draw conclusions, but I still need help..
Also, I have had the Tmobile Sim card replaced twice..
If someone could help find a solution, this will help a LOT people!
Thank You AHEAD of time.
did you flash the entire firmware package?
I only flashed official firmware from ATT to TMOBILE.. That was all. If there are further steps please let me know.
I stopped at the firmware install because I thought anything extra would have just been for customizing themes, etc..

Tmobile :"ATT did not unlock it completely, call them and ask for it to be fully unlocked."
From my understanding, there are no levels of unlock permissions. Once a device is unlocked, it's done on all levels and access.
It is unlocked by ATT - I received the code and used it with the Tmobile Sim card inside when prompted. Success.
The unlock code needs to be entered on device while connected to the ATT network...not TM's. My initial suggestion is kindly call back ATT and with the correct IMEI/ATT Sim inserted, enter unlock code again. You may need to flash back to xxxA first.
My thought here is the phone isn't unlocked according to ATT's server's Device ID data...when you reestablished connection with ATT, it locked the device again.
[Q]
You said that you got the unlock code from ATT, with TM Sim inserted, and it was a success....
Why did you go back to the ATT Sim again if you had it working?

Try this. Go to phone dialer, type in *#2263# , dont hit call , just wait for the menu. When it comes up, select GSM band preference and if its an option, choose GSM 1800. Then swipe down to exit.

The unlock code worked. I was not prompted to enter another unlock code. I received success notification. I immediately got the error code that you see in the pictures. Could not dial out. So i went to ATT store for some hands on troubleshooting. But I will try to use the sim card idea you mentioned. I will come back with an update.

The same here. I'm from Vietnam. My boss from USA visited Vietnam office and gifted me a T-mobile Gear S with the unlock code from T-mobile. Before unlocking the network, i upgrade it with the latest firmware from T-mobile (R750TUVU1A07). I then inserted a VN carrier SIM and did follow T-mobile guide as below:
1.Insert a Non-T-Mobile SIM & turn the Gear S ON.
2.The Gear S will automatically prompt you to enter the unlock code.
3.Tap in the unlock code provided by T-Mobile and click OK.
Note: The device should display code accepted

After i receive the successful message, i still cant make call or send message. It keep saying that "Mobile network is not available". I tried with 3 nano sim cards from 3 biggest carriers in VN but there is no luck. (These sim cards work well on the iPhone 5).
BTW, the GPS also didn't work, even before or after unlocking with the code. It keep saying "GPS signal too weak. Please connect the Gear to mobile device via Bluetooth" (or something like that).

You most likely will not be able to use a North American S outside the US. It has nothing to do with the software...the frequency bands are different and hardcoded. You may want to check and see what bands are used by the providers in VN for cellular ie: 2G, 3G, etc and compare those to what US/Sprint uses.
I have the same issues with the GPS. Even when I'm outside, in an open area I can't even get the weather app to update. Not sure how many people have this issue, but it doesn't seem to be a topic of discussion on XDA.

This is from "CELLUNLOCKER" where I got my unlock code...before it was free...lol....... When I click on the t mobile for network....I get "registered to networkk" popup with my ATT GS. When I call a number I get the tmobile cust servc help line...... since I am not a tmobile cust.
I cannot remember which method I used....but I can go with att or tmobile sims with no issues. Right now I have H20 as my carrier, on the ATT network...but at least I know I can go to the Tmobile network or carriers anytime
How to enter unlock codes on all Samsung models
Different phones have different Unlock Code Input Instructions, Try the following Instructions in order:
Note: Non Accepted Simcard is any simcard not from the original provider
Method #1 Insert a Non accepted simcard in your phone and power on. Once finished loading your phone will ask you to enter a code, enter the Unlock Code
OR
Method #2 (NOT applicable for newer Samsung phones, ie. Galaxy S3, S4, S5, Note 2, Note 3, etc)
Go to the dial screen on your phone as if you are going to make a call and press: #7465625*638*UNLOCKCODE# (8 digit unlock code)
OR
Method #3 (NOT applicable for newer Samsung phones, ie. Galaxy S3, S4, S5, Note 2, Note 3, etc)
Go to the dial screen on your phone as if you are going to make a call and press: #0111*UNLOCKCODE# (8 digit unlock code)
OR
Method #4 (NOT applicable for newer Samsung phones, ie. Galaxy S3, S4, S5, Note 2, Note 3, etc)
Go to the dial screen on your phone as if you are going to make a call and press #7465625*638*# Once prompted for code, enter the 8 digit Unlock Code.
When this method is used for newer Samsung phones, it will say "unsuccessful" regardless of the phone being unlocked or not.
Phone Not Allowed MM#6 Tmobile- A clue to problem?
I also have the same problem...it is frustrating.
i have an unlocked AT&T Gear S ( unlocked thru one of the unlock ebay sites. it seemed to go well, and worked)
i setup account with Tmobile, and it worked, i have had it about 2 months, all OK, until..
i took out SIM to test with my unlocked IPHONE 6+, (i have been thinking of switching all my phones to Tmobile) it also worked OK,
Then i swicthed it back into the Gear S, and the trouble started (unless it was a conincidence),
'Phone not allowed MM#6', it tried everything.
1. reset Gear
2.rebooted thru the gear boot menu
-i called Tmobile, they did not have answer,m they asked me to try a new SIM, which i did online and updated account with new SIM,
same problem.
3.Tmo said maybe not complety unlocked to contact AT&T but i doubted this,
4. I tried a freinds SIM from his Iphone 6+ (on Tmo) it worked great in my Gear Sm and my 'unlocked Ipphone 6'
5. i tried my Gear S SIM in my Iphone, message poped up 'Phone not allowed' (this time no MM#6)
6. called Tmo again (maybe 3rd time) suggested another new SIM card, they everything on there end looks fine, they checked imei, sim card etc, all OK.
i told them from what i have read the forums mentioned a network problem, not a phone problem.
They connected with Samsung, they said they can try reflashing the Gear S, if i send it in to them,
7. i called Tmo again, and i spoke one rep who , GAVE ME A CLUE TO PROBLEM.. he found a note concerning the Gear S,
it said if the user puts the Gear S SIM cards (wiith the 'wearable plan') into another phone, it will block the account until the user reinstalls SIM into Gear S.
8. if this the problem, iit is not reseting itself when SIM is back in Gear S.
9. Not sure what to do next.
the last Tmo rep told to go into Tmo store, and they will try another new SIM, and ask them to try new SIM and my in anoother Gear S, but it seems many tmo stores dont have Gear S on hand, only display it am checking.
10. One idea may be to close the whole account and open new account for the Gear S.

I also have the same problem...it is frustrating.
i have an unlocked AT&T Gear S ( unlocked thru one of the unlock ebay sites. it seemed to go well, and worked)
i setup account with Tmobile, and it worked, i have had it about 2 months, all OK, until..
i took out SIM to test with my unlocked IPHONE 6+, (i have been thinking of switching all my phones to Tmobile) it also worked OK,
Then i swicthed it back into the Gear S, and the trouble started (unless it was a conincidence),
'Phone not allowed MM#6', it tried everything.
1. reset Gear
2.rebooted thru the gear boot menu
-i called Tmobile, they did not have answer,m they asked me to try a new SIM, which i did online and updated account with new SIM,
same problem.
3.Tmo said maybe not complety unlocked to contact AT&T but i doubted this,
4. I tried a freinds SIM from his Iphone 6+ (on Tmo) it worked great in my Gear Sm and my 'unlocked Ipphone 6'
5. i tried my Gear S SIM in my Iphone, message poped up 'Phone not allowed' (this time no MM#6)
6. called Tmo again (maybe 3rd time) suggested another new SIM card, they everything on there end looks fine, they checked imei, sim card etc, all OK.
i told them from what i have read the forums mentioned a network problem, not a phone problem.
They connected with Samsung, they said they can try reflashing the Gear S, if i send it in to them,
7. i called Tmo again, and i spoke one rep who , GAVE ME A CLUE TO PROBLEM.. he found a note concerning the Gear S,
it said if the user puts the Gear S SIM cards (wiith the 'wearable plan') into another phone, it will block the account until the user reinstalls SIM into Gear S.
8. if this the problem, iit is not reseting itself when SIM is back in Gear S.
9. Not sure what to do next.
the last Tmo rep told to go into Tmo store, and they will try another new SIM, and ask them to try new SIM and my in anoother Gear S, but it seems many tmo stores dont have Gear S on hand, only display it am checking.
10. One idea may be to close the whole account and open new account for the Gear S.

Call tmo back and have them make sure you have the right data plan I had the same problem and mine was on a tablet data plan not mobile/watch plan
I am experiencing a similar issue with TMobile. My thread is in here, http://forum.xda-developers.com/gear-s/help/gear-s-longer-able-to-register-tmobiles-t3040635
I have the factory unlocked international version, SM-R750W, and several people here said it wouldn't work. It worked perfectly for a day, then nothing. New SIM, it worked perfectly again for maybe 5 minutes.

Still no luck, but maybe a couple more clues;
1. As the tech support advised, I went to a Tmo store, and they swapped the nano sim , no help.
2. I put in a sim from my friends tmo iPhone. It seemed great.
3. I called tech support back, they escalated problem to the engineering dept,
Said it may take 2 days to hear back...... So far no luck, please let me know if you have better results.
(I did check the plan online and with support to be sure it was correct.- the wearable / watch plan)
I feel it has something to do with there network 'rejecting' my imeo, but support checked that several times, as said it is correct.

They escalated my situation as soon as I called them on Tuesday and told me 3 days. Nothing yet.
Have you used the Tmobile IMEI check? http://www.t-mobile.com/verifyIMEI.aspx
I just tried it and it doesn't recognize my IMEI....But if that was going to be a problem, shouldn't that have meant it would never work? I can't think of any reason it would work for a day before they shut it off.
I had same result "did not recognize" with there Imei checker, further, the support reps checked several times and said it is Ok, My gear s is an unlocked AT&T, it did work for the first 2 months (until I removed sim to test in my iPhone ( I was considering switching all my phones to Tmo) Maybe coincidence? + But with a friends sim (from his iPhone ) it worked immediately , it even populated the Apn etc settings, but i did not leave on more than 1-2 minutes to test.
When I put my sim back in, it does not register, it does even show phone number, says:
"Phone not allowed MM#6" and emergency calls only.
I had this same issue come up. The way I solved it was to close out the account for my phone number tied to the watch wearable plan. And then I created a new phone account for the wearable plan with a new number. And got a new sim card from T-Mobile at the time of creating the new wearable plan / number. It seems that the phone number that was previously tied to my galaxy gear s was not blacklisted, but the services were limited on it because I had taken the sim card out of the gear s watch and put it into a cell phone to test if there was service on it. So that flagged the wearable phone number account like I was trying to steal data/phone service from T-Mobile by using the only $15 / month plan on an actual phone. Like said above, the services are supposed to be restored once you put the sim back into the watch, but there is a bug with T-Mobile's service in doing so. So in the end, I closed out the "flagged" account, opened a new account and will never put the sim card into a phone again in the future.
same the issue

The same here. I'm from Vietnam. My boss from USA visited Vietnam office and gifted me a T-mobile Gear S with the unlock code from T-mobile. Before unlocking the network, i upgrade it with the latest firmware from T-mobile (R750TUVU1A07). I then inserted a VN carrier SIM and did follow T-mobile guide as below:
After i receive the successful message, i still cant make call or send message. It keep saying that "Mobile network is not available". I tried with 3 nano sim cards from 3 biggest carriers in VN but there is no luck. (These sim cards work well on the iPhone 5).
BTW, the GPS also didn't work, even before or after unlocking with the code. It keep saying "GPS signal too weak. Please connect the Gear to mobile device via Bluetooth" (or something like that).

So, right now, the Gear S is just a digital watch to me, ha ha.
The error is specifically a sim/network error unfortunately and more importantly this;
9 out of 10 times MM6 error means the phone has been reported lost/stolen and the IMEI has been network blocked.
Here are a few options that could be causing most of the issues I have read;
At&t is NOT open and a fan of allowing devices outside their network. Therefore its possible your device is literally reported as lost/and or locked to at&t and they dont want it on T-Mobile. And your best bet is to raise hell threating an investigation by the FCC.
At&t re-locked your device when att sim is put in.
