[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.

Unlock Code From AT&T Not Working - What Can I Do? [HELP]

I was given the unlock code and it still says request to unlock network unsuccessful, it's eligible to be unlocked...
All help would be greatly appreciated.

Should I try flashing over back to this stock rom and then see: http://server10.stockroms.net/download/GalaxyNote2/SGH-I317/I317UCALJ2_I317ATTALJ2_ATT.zip
I hate being stuck in a rut like this, already had my account transfered to a T-Mobile microsim. This is driving me nuts...
The person I bought this phone from said they updated but then when I checked it was still at 4.1.2 and said something about update interrupted...

Or which of these should I use: http://www.scottsroms.com/downloads.php?do=cat&id=71

Flashing a Rom won't unlocknyour phone..... Also what do you mean your still on 4.1.2?? That is the latest Rom for the phone. ... Where are you obtaining your unlock code from? The only time att provides it themselves is over the phone. You sure your not getting the wrong code?

Yes I got the code from AT&T over the phone, called them twice and got the same code 1-800-331-0500 they gave me 41907314... According to this: http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unlock-sim-for-free-on-gsm-galaxy-note-2/ if ya take the newest update, ya can't sim unlock the phone cause it takes out the “NW Lock NV Data Initiallize” (Step #9) according to YouTube user comments...
THIS IS WHY I'm wondering what Stock firmware I need to downgrade back to in order to get that option again and be able to sim unlock my phone.
So I'm wondering if it's I317UCALJ2 or I317UCALK7 that re-enables that option for me. Right now I'm on I317UCAMA4...

Sorry bout the 2 posts, I thought it'd auto-append them to my main post...

Okay now I keep getting errors on installing about a signature and then two file locations sdCard0 and I think extsdCard...
How can I fix this do I copy the image to sdCard (InnerSD)? Or do I need CWM to install for Scott's Stock ROMs?

Yup that worked, I had to use Odin and this image http://server10.stockroms.net/download/GalaxyNote2/SGH-I317/I317UCALJ2_I317ATTALJ2_ATT.zip and followed these instructions on installing it: http://androidromupdate.com/2012/11...y-note-2-sgh-i317-original-factory-stock-rom/ then unlocked it with the directions galaxynote2root.com had listed...

No I mean while doing this process? Odin thing.. does it matter which SIM I have to keep in note

This http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unlock-sim-for-free-on-gsm-galaxy-note-2/ is the tute I believe, gotta remember it's been 2 months since I did this, so I'm not quite 100% certain. LoL
I'll be having to do it all over again too, by the end of this week possibly, since some jerk decided to steal my note 2 I had to go to ebay and win a new one.
I don't think it'd matter during the Odin flash with a AT&T sim card or T-Mobile one in it, I can't remember if I did it with or without a sim card, but to be on the safe side I'd do it without a T-Mobile sim card in it, just for that first successful boot... Then do the 4.1.1 unlock code method, take the back and battery off then pop in the T-Mobile sim card(Or whatever other non-AT&T carrier sim card) and see if it done it correctly...

I bought an AT&T live demo note 2 that was used in an AT&T store. I used this method from youtube, popped in my niece's T-Mobile microsd and dialed 611. T-Mobile's customer service rang and answered showing it worked. You need 4.1.1 to use this method though. I'm going get me a microsim today since my vibrant doesn't use the micro.

The above is not true - if your phone has upgraded firmware, you will NOT see the item "NW LOCK NV RAM...." in your "NETWORK LOCK" "PHONE CONTROL" menu.
So, the ONLY two solutions are:
1) keep bugging ATT to create a case for you and investigate
2) downgrade to 4.1.1 modem (NEED TO READ/UNDERSTAND HOW TO FLASH etc.)
then apply the Samsung service menu "fix" as shown in the above video...*
*Then, you could upgrade to newer ROM... if you wish....:cyclops:

I'm trying to unlock my phone, I bought used on ebay, I found found a thread here that shows you how to unlock, but can't even do the first step. when I install a different sim card, I don't get the message Unlock, the phone reads the sim as a non support sim.
the sim I'm putting in the phone doesnt have service on it, Is this the reason the unlock message doesn't come up?

Anyone have any idea?
Thanks for the reply

you can use free unlock from general http://forum.xda-developers.com/showthread.php?t=2024514
but of course you have to do it from uvkl1. but--you can do a nandroid, and after you unlock it, restore your backup! it will stay unlocked

Seems your phone's ROM/Radio mismatched or not for MetroPCS. This exactly happened to my phone also, until I flashed a new radio for my rom(I am using TMobile, flashed new TMobile ROM but not new Radio. Then it had the problems as you have now).

New sim fixed

By Sim unlock, do you mean you want to use an AT&T phone on another carrier? If that's what you are looking for, give me a few minutes to test something.

Yes, of course.
But I am fairly new to the note 2 so I don't have much stored up information. I now see a post that indicates that flashing a certain 4.1.1 modem, MJ2 I think, gives the user a service menu where you can change the unlock setting. So now the OP's question makes sense. Only he should have been able to find the same post I did.
In a minute, as soon as my wife lets me borrow her phone, I'm going to test an unlock tool I know about to see if it works on 4.4.2 stock.

The dialer codes that worked on 4.1.1 to unlock the phone via the hidden menu. Does not work on 4.4.2 anymore. And being you took the ota update, there's no way of downgrading you firmware...
Sorry to tell you..
Another way is to contact AT&T by email, about unlocking the phone. Can't remember what the exact name is, but goggle search it. They'll send you the SIM code, if the phone is out of contact!!! Takes about 2-3 days when I did my skyrocket to run on TMO.

Sent from my T889 N2/N3/S5..

At one time, there was a free app on XDA called GalaxSim Unlock. For some reason, the developer pulled the free app download, and the only version then available was the paid version on Play. I have a copy of the free one from before it was pulled, and it works on the Captivate and the Galaxy S II, and some other galaxy phones, not sure which ones. So I tried it tonight on my wife's Note 2 which is running Stock NE5 with TWRP recovery and has the MC3 boot loader. However, the unlock failed, saying unable to read nvdata. So it's apparently a no go on this phone.

That only works if the contract the phone was in was not defaulted, and or you are the original owner of the phone.

re: sim unlock
I recently bought a soft bricked SGH-I317 (stuck on "firmware upgrade encountered and issue"). I tried flashing LJ2 firmware and got it to change to being hung on the "Samsung Note II" logo. I think this is when it changed as I was trying all sorts of flashing trying to get off the "firmware upgrade encountered an issue" screen (also Kies would not recognize that the phone was connected). Tried different recoveries and firmware without making any progress until I flashed the 4.4.2 (I317UCUCNE5) bootloader. The phone booted into Philz recovery after that. I then flashed the stock LJ2 firmware w/ LJ2 modem, sim unlocked the phone and then flashed Skynote Air 4.3 along with the 4.4.2 (NE5) modem. This is the setup that I am using on T-Mobile now with no problems except that the Knox counter is tripped. Hope this helps shed some light on the problem.
I discovered a problem with Skynote 4.3 with the 4.4.2 bootloader. If I try to charge it with the phone turned off, the phone will freeze at the empty battery symbol and requires a battery pull to get the phone to turn on. Everything else seems to work okay.

My sister sell her note 2 to me because she's gonna upgrade to samsung galaxy S5. It was an att and I'm using T-mobile.
I did check the baseband ver and It was i317UCUCNE5 (4.4.2 OTA). the question is it is safe to flash base band ver i317UCALJ2 using ODIN?
Can you do the step by step process and also links of the files and software did you use please? thanks

It's a network unlock, so you are free to use any GSM carrier. You can lock your sim card -- then a pin is required for your phone to connect to your carrier. It's the old skool method to stop unauthorized use, from the days before a lock screen pin.

I bought a SGH-I317M today off someone. It was locked to Bell Canada. I did the dumb thing by letting Kies update the firmware. And as i've read I'm pretty screwed for downgrading it. I tried unlocking it but the hidden menu didn't give me the 4th option in the network lock path. So i tried bunch of things which at one point required me installing Kies for drivers and thats when I i let it slip and update. So now I'm still searching for a method to unlock my phone. I've gotten philstouch recovery on and Skynote working. I just tried flashing the rogers_j2 modem.. hoping this will work.. you think I should just pay one of those sites or a retailer for the sim unlock ccode?

Please let me know if it works. mine is galaxy note 2 4.4.2 NE5 baseband and I've done some research and they said that if you upload your firmware thru OTA there is a possibility that it will soft brick you phone due to unknown security reason.
I'm just waiting for conformation from some one that it's safe to flash J2 modem on a NE5 OTA

in the US, if your phone is more than 6 months old and your contract is in good standing you can ask for the unlock code. I don't know if Canada is similar.

I was going to post the same question about unlocking I317 4.4.2, and found this post which is similar to what I'm looking for so just want to add to pump the question.
It's been a while but I have done unlocking for other At&t models (S3, S4) and learned that later versions don't with the option in hidden menu to unlock, and the work around is to downgrade. However with devices that have OTA updates, it's not possible to downgrade the bootloader.
Is this the same for Note 2 I317? If so, any other method available to unlock this device to use it on other GSM networks? (I just bought one and it's on Kitkat 4.4.2 UCUCNE5, and looking for unlock...)

It's only the modem that needs to be flashed. So whatever bootloader you're on doesn't matter.

I wanted to unlock my phone today. ATT website wouldn't let me do it until my contract was fufilled, so I did some web searching.
Started with 4.4.2 and NE5 baseband. Loaded original baseband via recovery, and used the debug menu to unlock the sim. After that, updated the baseband back to the latest. Tmobile sim seems to be working just fine.

What bootloader were u on?
Sent from the TermiNOTEr 2! ?

[SOLVED][Q] IMEI and Baseband unknown. I don't have a backup.

[SOLVED] I put my phone in airplane mode and my IMEI/Baseband came back, cheking the service menu I went to *#2263# and saw that "LTE Preference" was enabled. I clicked on Automatic and problem fixed. Probably a ROM bug? Who knows.
Hello there. I've been a reader of the XDA forums for some time but I never had any reason to create an account to post on the forums.
A few weeks ago I got a SGH-M919 as a gift, the phone only had a few months of use and I took it with me, everything worked fine except for the fact that I couldn't get 3G/4G (Not even EDGE), I was only able to connect to the GPRS network and I couldn't change the carrier (It always gave errors like "Unable to connect. Try later" and such). Although the phone is (apparently) quadband (I don't live in the US), it just didn't work but I lived with it.
Yesterday my phone was low on battery and I turned it off, a few hours later I turned it back on and it couldn't connect to the network, I went to the network options and once I pressed the screen to enter the Mobile Network options, I got an alert saying that I must have a SIM to access those option. At first I thought that the SIM got damaged somehow (This isn't the case since it works perfectly fine in another phone) but after a few minutes looking around, I checked the IMEI and instead of the usual number, I got a null/null message. My first reaction was to google what exactly happened and the answer I received was that the Baseband (Which is also Unknown) and IMEI are stored in a folder called EFS and that it got corrupted. Sweet. I looked for solutions but the main two I got (EFS Pro and ADB nvrestore) require a backup of the EFS (Which I don't have).
The other solution I got was to restore to the stock ROM (M919UVUFNH7) which I'm currently downloading from SamMobile (Sorry if this is considered spam). The phone is not rooted and has the stock ROM, it came with a CWM folder inside the internal memory with an .img file but it doesn't have CWM intalled. I've never upgraded it (Not sure if it came with that firmware from the store if it matters).
I live pretty much in what can be considered a "3rd world country". So I cannot send it to Samsung nor I have access to dollars.
Another question is, the phone was gifted to me already unlocked, I don't know if it came unlocked from the original carrier or if it was unlocked via a code or whatever. If I restore to the stock will it lock my phone to T-Mobile again? Would I be able to use it without a SIM card if it gets locked? It's impossible for me to get a T-Mobile SIM on my hands should I ever need one. In the worst case scenario that my phone gets locked, can I get it unlocked by flashing a custom ROM?
I have so many newbie questions that are already answered in other threads, but since it's a lot of information I want to get it as specific as possible to avoid breaking my phone.
If someone can help me with this issue, I'd really appreciate it.

i having same issue in M919

Do you guys get a message in notification bar about sim car removed or something about a sim card? Also, it doesn't matter if the sim card works in another phone. This device has a little issue with being picky with sim cards. If it's a cut sim card, get an original micro sim card

Hi, thanks for answering. I don't get a message about a removed SIM card. I'm also using an original micro SIM.
I already downloaded the Stock ROM but I haven't flashed it yet.

This is a known bug of the s4. It is a hardware problem and I have yet to find a solution. If you google it you will find many threads on different forums addressing this issue. Again, no known solution

Any answer/idea about my issue? . Sometimes I can access Mobile Network Options, sometimes I can't. I can't configure the APNs (They delete themselves after I click on save). Phone Serial Number didn't get deleted (Which is stored inside the EFS folder as far as I know). I also can't select a Network Mode. I click on GSM/WCDMA/LTE but it changes automatically to nothing.

This is a known bug of the s4. It is a hardware problem and I have yet to find a solution. If you google it you will find many threads on different forums addressing this issue. Again, no known solution

That's what I said? One solution is to change sim cards if using a cut sim card to use an original micro sim. It's worked for a friend if someone I know and also for others on XDA. It's not the solution, but works for some

Hi, thanks for answering. I don't get a message about a removed SIM card. I'm also using an original micro SIM.
I already downloaded the Stock ROM but I haven't flashed it yet.

I would get a new sim anyway if I could. Flashing stock firmware wouldn't hurt as well

Before trying to flash it, is there any risk of getting simlocked again? I wouldn't want to get my IMEI fixed just to realize that my phone is locked to TMB again
UPDATE 1: My IMEI and Baseband randomly got back (My IMEISV was still missing) but after I restarted, they got deleted again.
UPDATE 2: Rooted, went to EFS, didn't find nv_data.
