[Q] Device won't connect to any network

Hi, I have an SGH-I747M that was originally purchased through Bell. In an attempt to unlock to make it work on Koodo, I went through SamMobile (after reading there was no way to unlock post 4.3 OTA update) and that seemed to half work.They resell a service from 123unlock.nl which is a client that uses adb or something of the sort to mess with phone files. The program afterwards said "Your phone is now unlocked! However if you don't see any carriers you need to do something in the advanced option and pay another $2x.xx dollars to do so". I didn't feel like giving them any more money at this point because I was upset that what I originally paid for didn't work properly. The fix was apparently an option in the advanced options that was an NVM repair/rebuild or something of the sort. I should have screenshotted the issue but of course didn't.
Now, the phone will boot up and does not offer me a SIM unlock option anymore. When searching for carriers it will ever only find Rogers for some reason. It won't recognize Koodo or Telus or anything of the sort (or bell when my bell SIM is in). Every now and then when it boots up, it will successfully send a text but only within a 5-10 second time frame after boot (I've made 1 phone call as well for 3 seconds). I've tried the Koodo SIM in my own Nexus 5 and works fine so the network is okay at least (plus I called Koodo and they verified on their end things look good... if that makes a difference). The SGS3 won't even accept an original Bell SIM at this point. It's always on either no network, 1 bar or full bars, never anything in between. I've tried flashing different ROMs from Bell stock to Koodo stock and CM11 and it won't work no matter what I do. Under all ROMs it pops up an "ME Returned temporary error" message on the screen.
I'm hoping someone might have seen this issue before or know what's going on with the phone that I can fix. I'm assuming it's something to do with the modem part of the phone that's refusing to connect to carriers but I'm at a loss to fix it. I haven't tried flashing different modems on it yet because I'm unsure which one would be a good fix and no one has had roughly the same issue I could find in 3 days of Googling for this issue. Any ideas are greatly appreciated. Thanks.

Can you check your phone's settings => About Device and let's know what parameters you have there (Android Version, Baseband Version, Build Number>.
You mentioned you can send text or make call within a limited time frame. Was that with the Koodo SIM or the Bell? If the former, it would suggest the phone is unlocked to some extent but you are probably experiencing a baseband failure or need to correct the APN settings. Did you also try doing a factory reset?

The information you're asking for is attached.
The texts I got off were from the Koodo SIM. I have updated the APN as well, and I did do a flash back to stock resetting all settings through Kies emergency update. I found a little trick where if you softbrick it by trying to flash 4.1, it'll give you the "Please use kies" error and that'll take you back to full stock 4.3. I'm pretty sure the baseband failure is the option I need to explore but at this point I don't know where to go to fix this.
Edit: I read this online and tried it: "The 4.3 update introduces a "security feature" which requires carrier- or region-locked phones to be activated once on the original locked network before the unlock code will work." The phone didn't recognize any network with the Bell SIM in except "EXT" which I've never heard of before and it did not connect properly so that didn't work. I also read that inputting #7465625*638*# will give me the Samsung SIM unlock menu which it did however I don't think the issue here is with the root and I'd hate to pay $50 at this point to have that not work as well.

It's unlikely to be the regional lock as this feature means your phone will work with compatible networks in the region but not in other regions. You may, however, run Chainfire's Region Lock Away to be sure <http://forum.xda-developers.com/showthread.php?t=2470551>
Your firmware settings look OK so I'd be doubtful about a corrupted modem. You may still try to re-flash the modem via custom recovery. Download link for the CWM flashable zip is available here ... http://www.androidfilehost.com/?fid=23252070760973552
The guys who sold you the original code seem to have sold a dud as there is no reason for them to be asking for secondary payments and this sounds like the footprint of a regular scam. I'd be surprised though as they seem to be well rated

I've tried reflashing the modem and I've actually paid $50 for the unlock code from Bell, the original carrier. I used the code to get the network unlock menu and inserted the code. I still get between 1-4 bars now with no network access on either network. It's not showing anything except Rogers still in network operator selection.
Any ideas at this point? It refuses to connect to any networks. I'm out of options.
Edit: I don't know if this makes a difference, but when I do root explorer I can't actually find the nv_data.bin file. It doesn't have anything of the sort in the /efs folder.

Please let me understand a few things ... when you first acquired the phone, was it working normally on Bell prior to the first unlock attempt or you never used it at all until you tried Koodo? Secondly, was the unlock code you got from Bell identical to the one you got from the online service?
I'm trying to establish if it is a case of hardware failure not reported by the previous user especially if you bought it pre-owned from the secondary market. If you are not sure of the previous usage history, it could be a faulty or disconnected antenna which may require professional service. On the other hand if you are sure it was working fine prior to the unlock attempt, try the following ...
1) From the dial pad, enter *#197328640#
2) [1] UMTS
3) [1] DEBUG SCREEN
4) [8] PHONE CONTROL
5) [6] NETWORK LOCK
6) [3] PERSO SHA256 OFF
7) Press Menu => Back button and go all the way back to Step 3) above
8) [6] COMMON
9) [6] NV REBUILD
10) [1] NV REBUILD
Reboot and restart and let's see if this does it.

I've got a similar symtom different scenario (sister in-laws phone). I was also only able to see Rogers network on a search. I've got Telus version. It was working fine until it was brought to the Philippines, got unlocked there and brought back to Canada.
I was only able to see Rogers network until I went into the Service Menu (similar to above) and found the option to change the band. I changed it to Automatic. After that I was able to see Telus network. When trying to connect/register it would take a long time and give me an error "Unable to connect, try again later". I still need to do more troubleshooting, but that might be something to look at.
Note: Phone has stock MOD ROM, rooted and unlocked.

Baseband with the Metro ROM is G920T1UVU1AOCH, but the problem is, I flashed both of the S6's I have here to the Metro ROM to unlock them so I have no idea what the original baseband was lol I hope you do!
Any luck on the S6 Edge unlock? I scour the internet everyday for developments but I havent seen anything I feel like this S6 Edge I have is either going to sit here forever or Ill have to sell it as a blacklisted phone because its financed and I KNOW its going to get blocked.

the fact that baseband has a G920T1 means that it did changed the radio , while every damn firmware i tried never change the baseband ., is good to know though ... and if you have an S6 Edge try this before selling it .. ask to borrow someone's tmobile sim card and try to at least do a temporary unlock if that doesn't work then download the app VyprVPN select germany (i did) with the tmobile sim still in and try temporary unlock again,,, doing this at least it bought a month's use of my phone , maybe a solution will come up later on.

So youre saying that when you flash the Metro ROM to it, its not changing your baseband? I used the one posted by UnlockBase. Were you able to successfully unlock yours?
And yeah, Ive tried the TEMP and PERM unlock on the S6 Edge. I put my TMobile dealer SIM in it hoping that would help as its a free $80 monthly demo line I get for selling TMobile service. I would gladly try that method, but since we sell these phones, a TEMP unlock wont help me I need a permanent solution so once I sell it, Ill know the customer wont have any issues down the road. I have both of the S6's up for sale now that they are unlocked, but I have always wondered if Samsung REGION LOCKS these phones. Ive tested my personal ATT line in it, and it works great, but alot of my customers on eBay export these phones overseas, so Im hoping these new Samsungs arent region locked :/

when you try to flash any firmware with odin it ends on FAIL.. you can flash rom with twrp but baseband remains the same ,, so i dont know if the unlock app from tmobile is tied in the bootloader or radio or something else ... so far i'll just enjoy the 30days left and see what happens after that ... cause after it accepted my att sim card a message will appear reminding me the unlock was to end on Jul01 and if i wanna to do permanent unlock, so i flash a firmware from a canada version G925W so the reminder went away but i dont know if that means that in 30 days i'll be locked again

I gotcha. I did something similar. I flashed the international ROM on the S6 EDGE via TWRP and it told me the code is incorrect. I know the code is correct because if I ever it in with no SIM and the #7465625*638*# and put the code in it says successfull. This is SOOOOOO frustrating. The lock has to do with the radio or the bootloader/baseband.

I am interested to see if that works which it may as the app is not there to retrigger the lock. You never know.

I currently have metro pcs and I bout an unlocked Samsung galaxy s6. My original Sim is too big so I have to go to metro to get a new one but the phone is not reading the new sim in order for them to program it. How do I fix this or get around this? Should I not let metro try to activate the phone?

Possible to change n975ui to n975u?

I flashed att firmware on an unlocked note 10 plus but att still sees it as an unlocked phone. Is it possible to change the phone to completey read as an attvbranded model? I called to see if they could provision the IMEI of my phone and they were able to tell right away it was not one of theirs, even though it was running att firmware.

No, because (as you found out) the IMEI number is not from an AT&T branded phone.

I have a GOOGLE unlocked phone. I flashed N975U firmware on my phone and also flashed ATT USER DATA at the same time.. When my phone booted up - it had all of the ATT BLOAT that comes on an Att phone - it booted up with the ATT LOGO - it shows ATT ICONS in the Status Bar for Data (5GE instead of showing LTE or 4G) and I have Wifi Calling and Video Calling working on my phone...
https://androidfilehost.com/?w=files&flid=301224
That is all it took. I didn't have to call ATT - It all just worked - and it was not working that way BEFORE I flased Userdata.
YMMV but I have heard about others who had the same experience. Go tot he N975U Firmware thread and find the download for ATT USERDATA - That is where I found it....
Hope that helps you.....

Pixel and iPhones are supposedly able to do those things. I think that may be why it worked for you

Wish it was possible, but unfortunately no way exists.

If you have WiFi Callling, Video Calling and Volte working, why does it matter if ATT recognizes your phone as one of theirs or not? Just curious about what you are trying to accomplish ?

SM-N975U Att note 10+ service issues

I have a att note 10+ that I sim unlocked it will take a Verizon sim and work 100% but it will not work with straight talk i have no service can't call text and no data every once in awhile a text will get thru but can anyone help me with this I can't root because I can't oem unlock unless there is another way any help would be appreciated

Did you set the APN information correctly?
Also are you using the N975U1 firmware or the standard AT&T firmware?
Are you using the BYOD sim card from straight talk?
What have you done over the phone with Straight Talk as far as troubleshooting? - this one can be important. If the phone isn't working with straight talk only it maybe a configuration (apn setting) or provisioning issue.
Are you sure the device is compatible with the area or region your in?
What provider/tower (Verizon, AT&T, etc.) does straight talk have you going through?
More information on what you have done to setup the phone for straight talk, troubleshooting steps you have taken, what information straight talk may have provided (etc. etc.) will help others be able to help you. Providing little or no details makes it rather hard to offer any help.

The apn won't let me put dun in the type I sim unlocked it with a puk code and got strighttalk byop I tried flashing the U1 firmware to it wouldn't take it so I did a Verizon firmware thinking that might help and same thing with the striaght talk it doesn't wanna work i put a Verizon sim in it and it works just like it did on ATT so I'm confused as to why the straight talk sim won't work they can't figure it out on their end either

I factory reset the phone reset network settings did just about everything I could with the phone besides it being funny about the apn cuz it says apn cannot be changed on this device if you put dun in the apn type i dunno the only thing I notice is when the Verizon sim card is in the phone the network mode is set to global whereas with the striaght talk its LTE/CDMA and it won't let you change it to global

Straight Talk uses different mobile providers to offer service different areas.. They utilize Verizon, AT&T, Sprint and T-Mobile (Sprint and T-Mobile have merged recently, but Sprint towers are still active).
I have seen posts across the internet that indicate you should be using the U1 firmware on the phone.. I would make sure your converting the phone to the U1 firmware properly.
If I recall correctly (this is how I did it previously) when flashing the U1 firmware make sure your doing it without the sim card installed and using the non home_csc file. Factory data reset the phone after you successfully flash the U1 firmware and then insert the sim card after setting the phone back up (so it can apply the new sim/network settings).
I would strongly suggest you do not restore a backup during initial setup when you do this. If you restore a backup it may restore previous network settings/configurations that were for what you had previously.
If flashing U1 firmware doesn't help (and since this this is a Straight Talk specific issue) then it's more then likely on the end of Straight Talk. I would call them and make sure that your sim card is the correct one for the cell towers they have you going through and the phone you have. Using an incompatible sim card (or one that is faulty) can cause issues like this. You can also have them send you another sim card to try.
Also contact them to make sure the service is properly provisioned and activated on your phone. Double check the APN with them, and see if they have an alternative one to try. It is also possible that a service outage maybe (or issue with Straight Talk internally) in your area, so I would call them to make sure that neither are not the case here.

The Global setting doesn't really matter in this case and your phone will be set to use the towers that Straight Talk has you going through.
The only thing that I can think of that would be a problem with network mode is if your sim card from straight talk is meant for a different provider then the towers they use in your area (i.e. sim card is for AT&T but the provider they have for the area is Sprint).

the straight Talk sim works in other phones no problem a s8 and a older note im thinking att has something in the software to block other apns i dunno i unlocked it with a PUK code and flashed verizon firmware on it thinking i could get passed it but the verizon sim works 100% and the att sim works 100% too but a straighttalk sim card (verizon) towers the phone tries it shows 4g and disappears and then it shows it has service but cant call it just says emergency calls only

I would not use older phones as a means to say the sim card is good. Besides that's irrelevant to what is going on with the Note 10+

Then this means one of two things... Either you didn't get the phone unlocked or else you did not convert to another carrier (or the U1 firmware XAA region) correctly.
If your using the unlocked firmware (U1 XAA region) then you should be able to edit the APN. If not then you should be able to create one.

That sounds like either the sim card isn't good, the phone was not activated/provisioned properly in there systems (call them and double check IMEI and model information), the phone is not compatible with the service they offer in your area (I suggest using the XAA region U1 firmware in this case) or else your phone is not fully unlocked.
I would also suggest google searching or else asking them for any updated or alternative APN's to try. It maybe very likely the one you have is not suitable for the phone/area... It wouldn't be the first time I have had an issue similar to this like this.
I am opt to believe the first 3 are the most likely scenarios since the phone works on Verzion with the sim card per your indication.

Yeah and the only reason I tried the older phone is to see if the sim card is activate with the number and the phone itself pulled the apn from network when I tried to flash to U1 the phone gave me a error but it took the Verizon firmware for the 975U but its still not working do you know of a good link for the firmware your talking about so I can try that

From personal experience I would advise in the future you don't do that. When you activate the phone you should activate the one you are using and definitely do not use an older phone to activate a newer phone. I have had many problems with this in the past as provisioning for an older phone didn't always work for my newer ones..

I waited for you to give more information on the issue, but you didn't. So I am sorry, but if you don't provide the details of what is going on it makes helping you very difficult. You didn't say what error you are getting, what the firmware version(s) are of what your trying to flash and what is currently on the phone.
Here's the last piece of help I can offer now.
I can tell you that the following can be found on the forum by searching:
Links and how to obtain the firmware - Multiple threads asking the same question exist here. Also Frija, SamFirm, SamMobile are just a few examples of what can be found referenced here.
Bootloader version(s) - what will happen when you try to downgrade and what will happen (along with a important thing) when you upgrade.
Websites to find firmware - SamMobile and some others have been mentioned.
Patched Odin - In case you need the latest version it has been mentioned here already.
I can also tell you that by using Google and searching for SM-975U1 XAA on Sammobile does in fact work.

Brother give me root file for note 10 plus SM-N975U android 10 version one Ul version 2.5 plz help me

Can someone tell me what version of note 10 ive just brought?

Hi guys just got a new phone supposed to be uk unlocked sim free brand new.but its weird
The service provider sw ver dont look english to me
SPR/XAA/VZW
I have my ee sim card inserted and it works to make calls. But there is a weird notification saying OMADM activation not completed
Also says LTE on the screen something I've never heard of or seen here in england we use 4g volte.so I'm confused also the software for uk phones are BTU/BTU/BTU OR XEU/XEU/XEU
And last the box is weird as it says unlocked by Samsung and has a warming saying reproductive harm I was thinking wtf is this phone.
Also it says Qualcomm on the top on a sticker,we use xenox version england
Ps I brought it from Amazon uk

none of it of sounds like a uk version. more like a us one.

Is it new?

Yes from amazon uk
So this phone cant be used here in England then other than making phone calls ?and how do I get uk firmware onto the phone?I'm a noob and not good with computers
Also changing the csc codes to uk what will that change?as we dont even have the snapdragon model in england?so would there even be uk firmware for an American phone?
Google tells me spr means sprint and that's the first code of the 3
Vzw looking on google means Verizon and that's the 3rd code so the phone was originally a Verizon locked phone.thats was unlocked and flashed with sprint fw, because the second csc code says xaa and apparently that means unlocked.
So what does this mean for me a uk user.luke I said in the uk our phones are BTU/BTU/BTU or XEU/XEU/XEU if there uk and unlocked

If you have a active sim, try inserting it.
It should come online.
My unlocked 10+ I just got did, zero issues.
If not I would return it.

How can I flash uk xenox firmware onto an American snapdragon phone?.I'm a beginner when it comes to this.as I only buy uk phones as I'm in the uk and it seems complicated flashing stuff this handset is a u version and I want to make it the f version

You cannot flash UK firmware on your US phone.
Just return it to Amazon, claim full refund as the product is not as advertised: no UK unlocked version, not new. Also screenshot in post #8 refers to firmware of a Note 9, not a Note 10 (N960 is Note 9), this makes this phone even more suspicious...

Return it. There's a lot of bs going on with sellers of this phone. This has gotten really bad. Amazon, saw some deceptive advertising there recently for this model and the N20U.
Best to contact the seller on the phone first; no phone contact, don't use. Make sure you are given full specs on their site and it's compatible with your country/provider.
Buy only a new one if possible. Used ones may be running on Android 11, you don't want that!
I was able to find a reliable US vender and got a new umlocked 10+ 256gb/12gb Snapdragon about a week ago for $800. It was as advertised except due to its manufacturing date is running on Q not Pie. It's a keeper.

Oh sorry it's a note 9 i apologise.so if I cant change it to a uk firmware is the phone useless to use in the uk other than to call people?because my sim card works to make calls
Also OMADM activation not completed message is pissing me off
What does it even mean.i think my phone has sprint firmware on it?how can I change it to normal unlocked firmware so it's nothing to do with sprint I cant stant that OMADM ITS MAKING ME MAD
And Verizon is what I think the phone was originally.
Last thing the phone was sold as brand new sealed but it's not even in the correct box the phone I have is 128gb not 512gb
And it had a sealed sticker saying euro sim only but the phone is American? I think the box is fake ?as it looks nothing like any note 9 box I've ever seen

I'm going to try and flash the phone the phone is currently csc SPR/XAA/VZW boot loader 5 I've just downloaded android 10 also on bootloader 5 ovbisly the XAA VERSION will it work or can I only download and flash SPR FIRMWARE?
as I'm trying to get rid of the MADMEN activation not completed message

Update I tried to flash it but when I pressed start in Odin nothing happened so I guess I'm stuck on spr for life unless I forrgire out how to change the first csc

So it's impossible to flash to unlocked unbranded so it's going back to the scammer that sold it to me on amazon

It's not impossible but if you are not experienced with better get it back, it doesn't worth the try, you can end by messing up completely.

I've flashed phones many many times before normally when I update the fw via ota and then regret it and need to downgrade back .this phone I just flashed but the start button wouldn't work because I was trying to flash XAA VERSION and not the SPR VERSION .I guess if I was to follow a guide on changing the csc from SPR TO XAA then flashing will work but what the point i wanted a uk brand new factory sealed sim free handset like I paid for
So this pos phone can go back to the scammer on amazon.its a discrace they are making fake seals on the boxes.using fake accessories and lieing saying the phones are uk.the average person would fall for this lies because the phone is unlocked my uk sim will work but you get that OMADM pop up and it's a nightmare.plus I doubt half the functionality will even work.
