[Q] Phone issues

we unlocked this phone a few months ago and everything was working great.
last week sometime my son stopped receiving calls and txts and had a simcard icon showing that his sim card is locked. we did some troubleshooting with virgin and they determined he needed a new sim. so we restored this phone back to default and now there is still the sim card icon at the top of the screen. when we rebooted the phone it asks for a network unlock code. we were told by virgin to contact rogers to get this code. they were unable to help. i tried entering the unlock code that you provided us previously and we get an error unsuccessful unlock.
any ideas would be great.

so after almost two weeks of working with virgin and cellunlocker.net we still have not been able to get this phone working. im being told that sometimes when you update the firmware like we did the phone becomes re locked to the original carrier. i was sent a file to reload the stock firmware but the application just crashes when i run it. Does anyone know what i can do to get this phone up and running?? please help. thank you

Probably not a rom issue.
Probably will need to know what android version. ICS Official apparently has an issue with relocking from what I have read.

[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.

Note 4 International purchase in Australia Sm-910F actually is really an 910V

Hi all
purchased a phone from an online store in AUS which claimed to be a sm-n910F note 4 but had hacked software, after some help from this site it was identified as being an Verizon SM-910V in cognito, long story short flashed it with original sm-n910V software, when it starts its says Verizon and works fine on the Australian network. I plugged it into KIES and upgraded to Marshmallow firmware but I am one of the 900 Million phones that has the QUALCOMM vulnerability and I want to patch it when the security patch is released in september but when I go to use the software update on the phone it says this service is temporarily unavailable assuming because its looking for the Verizon network and I am on virgin residing in Australia. When I go into KIES it tells me there is a firmware upgrade but its trying to install the full Marshmallow firmware again. Anybody know of a way to trick the phone into thinking its on the Verizon network so it will download updates or could I simply grab the security download when its released and install directly to the phone via ODEN. Lesson never buy a phone that's coming from over seas its a real headache if you end up with something dodgy, thanks to anybody who can offer advice

Need to apply security update to SM-910V but not that simple

N7100, standard software, lost Network unlock after freeze, can't now unlock again.

Standard device, running 4.4.2, not rooted or changed other than by downloads provided by KIES, originally on 3 Ireland network, was unlocked and moved to Vodafone over 12 months ago with no issue, using unlock code provided by 3 after the end of contract period was reached.
Had a few strange issues recently but nothing I could be sure of, then one night this week, the phone locked and would not accept any key presses. Removed battery to force power down, then restarted, which has always worked in the past on the rare occasions when this has happened, but this time, when it restarted, it asked for a Sim Network Unlock PIN, which at the time I didn't recognise as being the unlock code supplied by 3.
I don't know if there are issues about the number of times this code can be entered, if there are, due to all sort of errors by Vodafone Support, that limit has probably been exceeded.
The other possibility is that a hardware issue has developed, but as it is only the phone network won't work, my instinct is telling me that this is a software and security issue that may have been triggered by too many failed unlock requests, though it still asks for an unlock code on power up.
So, what have I tried. After several frustrating calls with Vodafone and Samsung support failed to resolve the issue, I dismissed the PIN request and made sure I had some backups of things like Contacts, which worked, so the phone can communicate via USB, and it's also working with no issues via WiFi networking, as I can access things like Facebook via WiFi. My Google account is also working, it's downloaded and updated the applications that are installed on the phone,
In the absence of any real assistance from Vodafone or Samsung, in desperation, I've tried a factory reset, and also tried wiping the cache, but neither of these options are getting rid of the Unlock Sim request, which suggests to me that there is a flag or code somewhere deep in the system that's not allowing a full reset, and that may be related to too many failed Network PIN Entries.
Can I recover this phone, or am I better to just abandon it and get a replacement device, which in all honesty I don't need, the Note II is doing all I need at the moment, and a replacement is going to be an expense I'd rather not have to commit to right now.
I have all the details of the versions, IMEI etc, they are all accessible from within the phone using various *# codes, and they all are still correct and match what they should.
Talking to a local repair shop, if they ask for an unlock code, they are saying that the code they get will be the same as the one I already have received from 3, and as that seems to be not working, they are saying there's no point getting a code from them.
So, where do I go from here? Somehow, I think I need to find a way to wipe everything in the phone, and then reset the IMEI to the correct value, which should in theory allow the device to work again, and recognise the unlock code. That's a lot more than I've done on a phone, I'm computer literate, but not Android and phone experienced, so a lot of the buzz words are not familiar, or mean different things to what I've been used to on other systems.
If I am going to be completely wiping it all, is there any way I can change the service provider to get rid of the issues with the network unlock code, or is that asking for more aggravations?
Thanks in anticipation.

There is a free method that can be used to sim unlock the sgh-i317m which is the North American version of the Note 2. You had to flash back to a stock 4.1.1 ROM, and follow this guide: https://forum.xda-developers.com/showthread.php?t=2014982
The 4.1.1 ROM for the sgh-i317m Note 2 from sammobile.com does not include the 4.1.1 bootloader which is why the downgrade from stock 4.4.2 to 4.1.1 works.
