[Q] Note I (i717) ATT: Having signal issues/cannot connect to ATT network - AT&T Samsung Galaxy Note I717

Hello,
I'm currently having signal problems with this phone I recently bought on Ebay ( It was listed with this problem but i didnt think it was this bad lol). I only have 3G allocated to my current plan with ATT but it seems as thought this phone does not connect to the ATT network and when it does it goes out within 3 mins. I have read up on a few things regarding flashing a new modem on the phone and I have also contemplated replacing the antenna module located on the loud speaker part inside the phone. I saw a previous post on where the antennas are in the phone and I believe the one on the speaker is for 3G/4G/LTE.
I just wanted to know, if anyone has any other suggestion on best course of action from this point?
Note: I did update my APN settings correctly already.
Thanks in advance!

Search for a site online that can check if your imei is blacklisted. Or you can call at&t and ask. If you're blacklisted, all this effort will be pointless.

I've already looked up the imei and it is not blacklisted. Sorry I should have said that in the original post.

I've been having what seems like the same problem.
There's 3 threads I can think of on XDA with the same or atleast a very similar issue.
So far no one has solved it. Even by replacing the SIM tray. I genuinely think it's a software issue but I don't know enough about android coding to figure it out. I'm thinking it's time to learn JAVA so I can read all the code and the logs.

I'll let you know if I figure it out.

Are you 100% positive about the IMEI? Ended up being my issue.

[Q] How to get i777 working in Korea

I have an ATT GS2 running cm9 and I would like to be able to use it for the year I will be in Korea.
Is it possible to simply flash a korean modem and have it work here? (does that question even make sense?) Or am I SOL because I don't have the international version?
All I want is to be able to stick in a korean sim card (from South Korean Telecom) and have it work, if I am misinformed or simply uninformed about the steps needed to make that work please let me know.
I've been a lurker for awhile and this is the first problem I've had where I actually have needed to post. Any replies are sincerely appreciated
PS: I know I am a n00b and n00bs creating threads is like the worst thing ever, but I searched the forums for a good long while before posting. I also posted this question in the i9100 forum (http://forum.xda-developers.com/showthread.php?p=28207590#post28207590), but nobody replied.

My phone is unlocked and I put an SKT sim in it today and although it did not come up with a sim rejected message there was no cell service. I have heard about the modem that is flashed on your phone affecting cell service, so do you think I should find a korean modem and flash it on my phone? If not what can I do?

This is not an area that I know very much about, but I can give you some things to look into. First, as far as I know, you can only use an AT&T modem on the I777. There are a few options posted in the development forum, but they all work with the frequencies available on AT&T towers. I know the I777 is used in India, and a few other countries successfully, but I don't know about Korea. You have to look at what frequency your cell service is on, compared to the frequencies availabe on this phone. I'm guessing that you have a mis-match, but you'll have to do the research. So your original statement is probably true, that you would need the international version of the phone.
Edit: Did some looking around. You still need to check the frequency issue, but the main issue is that the SK sim card is locked, and you have to complete the following, which I grabbed from another forum:
For those of you who may not know, the rule currently is that every phone model that is not sold in Korea must be cleared by Korean Communications. They have an updated list of all models that have gone through testing and have been cleared so far (the N900 was already tested by someone else so I did not have to get recertification). The only requirement for me was to have the IMEI number registered with SK (this applies to KTF and LGT as well).
Just to summarize:
1) Make sure your phone is unlocked (not even a step really, common sense).
2) Check to see if your phone model has been tested by the KCC (optional step really as the list is very long and even some very niche phones have been tested already, if your phone is a model people have heard of, like you can just say the model name and 1 out of 10 people have heard of it, it'll have been tested).
3) Take it to your local branch office (SK/Tworld, KT/Qook Show, LG/uPlus) and make sure it is a branch office, not simply a retail outlet. The retail outlets are called "daeri-jeom" and the main offices are called "ji-jeom". You want to go to a "ji-jeom". There is usually 1 main "ji-jeom" per city.
4) Ask them to register your IMEI # and either purchase a SIM card or pop in your existing SIM car if you are a customer.
If you have an obscure phone that happens to have not been tested yet, there is an added step in the process that will take about 10 days and requires some paperwork but I won't comment on it as I don't have any first-hand experience going through that process.

And, in case any of you are wondering why I would take the time to do this. I have a very good firend, actually the daughter of a very good friend, who is from the small town I live in, and who is currently teaching English in Korea. I know she would probably not even know how to search for the correct answer. So... this is for Lily.
Thank you so much! As you may have guessed, I am just starting out as an English teacher here in Korea, and I will be sure to pass on this information to all my other teachers who would like to use phones here.

IMEI gone with no backup

So, a sad and dumb tale. I rooted my phone and through the process have erased my nv_data.bin and subsequent files from the efs folder. I was dumb enough to have not created a backup of the folder before losing these files. My IMEI is now a 0/1. Now I've searched all over for a solution but there apparently have been some people claiming it can be solved but noone has ever posted a guide to how to do this. Skeptical over a fix existing for this problem, i have called in to my carrier and claimed i would like to exchange phones citing that my current S3 is getting very slow. As my device is within the return time, it was accepted. However, if a fix is possible i would like to cancel the work order and keep my current one.
So, my 2 questions are basically this;
can anyone tell me if this problem is fixable, and if so, tell me how .
secondly, i have heard of people with the same problem returning their devices for new ones. I would like to know what was the carriers return policy and if they ever called back when they found your phone had no IMEI.
Unfortunately it doesn't look like there's currently a fix, did you only root it or did you root then flash stuff as well? as far as I've heard just rooting shouldn't have made you lose the IMEI, but I'm no expert.

you could try this http://forum.xda-developers.com/showthread.php?t=1308546
or search hc ktool in play store to see if either of those methods work, but since it's already corrupt it probably wont....hope it works!
As far as for returning, is your flash counter 0? if not and you un-root the phone theres really no way for them to know you messed with it and they won't care about anything and will replace it.
i didnt flash anything i dont think. i installed supersu using cwm...
so does anyone have any stories about returning their phones with broken IMEI's?

I read about someone who did this on the AOKP thread over on rootzwiki. He said he unrroted & returned it for another no problem, he had T mobile.
My dumb ass question for the day is this. What does it effect when your IMEI is erased? Does the phone still work or is it not reading the sim? I'm very gun shy to flash anything else until someone can figure out what is causing this issue...
im with a canadian carrier. virgin mobile. a subsidiary under bell mobile. so hopefully its similar case.
the imei is the number that the carriers recognize in order for them to allow u into their services. without a confirmed imei number on their network, u cannot call, text, or anything related to the mobile network. the phone still functions fine.

its an ongoing issue so far happening with att and tmobile sgs 3s( http://forum.xda-developers.com/showthread.php?p=28710945. backing up the /efs folder wont be of any help either if you do lose your imei as the lte sgs 3s are missing nv_data.bin in the /efs partition which contains the imei number.
something really weird happened today. I bring my IMEI broken phone around with me jus for music. but today randomly i got a bunch of texts, voicemail, and missed calls since the time my IMEI broke down. that must mean i regained access back to the mobile network somehow. when i rechecked in an hour. i did not have mobile network connectivity and my IMEI was set a 0/01 again.
maybe someone knows wth that was?
Out of curiosity, what partition does the efs folder live on? A factory reset or downloading the firmware from samsung-updates.com and flashing through Odin won't work. Forgive the ignorance. I just want to know if this applies to all S3's.

oddly enough. even though i have my imei is 0/01, i randomly get connectivity to the mobiles network on occasions. this has happened a couple of times now. i received a bunch of texts and calls, and then service is gone again.
any possible explanations?
The imei number isn't in the normal efs folder. I believe some very bright devs are looking into finding it, but for now there is no way to backup the imei.

This happend to me too. My IMEI read 0 /02. Good thing I was still within the 14 day return policy. I'm not doing any modding til this IMEI mess is resolved.
Yes, this did happen to me. My IMEI = 0 and my IMEISV= 02. All works fine except data and I'm stuck on Edge. I visited two T-Mobile stores today and they were baffled, but strangely neither bothered to look at the IMEI nor for the tripped counter. I purchased my phone on 6.21.12 and will be receiving my new phone tomorrow. I'm really wanting to get back to CM9/10, but think I will now wait until there is a backup/restore for the IMEI...or, I will not use Odin and trip my counter...that is what I'm most worried about.
I have yet to see any Verizon customers with this issue, nor do I seem to have an nv_data.bin file in /efs. I did have an IMEI folder, however.
Which recovery did you guys use that lost imei. If cwm...which one?

[Q] SGS3 Simlock Problem

Hello guys,
new to this forum and feel awkward asking for help straightaway. Recently my friend bought a SGS3 from someone, the phone was security locked (using pin security) so searched the net and found that hard resetting the phone would do the job and unlock the phone. Now the problem comes with simlock but i cant figure out how to disable it, its not like i didn't try but this problem is unusual.
I read the guides on this forum for removing simlocks and tried the *#7465625# which returns with "Not registered on network" i tried insertig a sim and it wouldn't accept the sim but it wouldn't ask for any sim code either. I found this thread http://forum.xda-developers.com/showthread.php?t=2023709 and after i reach the [6] Network Lock option it says menu doesnt exist. Also read this thread http://forum.xda-developers.com/showthread.php?t=1683348 but to no avail. I used esexplorer the first time to go through the files after rooting and dont know if it wasnt rooted correctly or what but it showed efs folder empty. So i reset the phone again and this time used another app and now i can see the files in efs folder.

Was the phone bought subsidized by a carrier? If so, they would need to release it, or unlock it.

The phone was bought used. I am not sure if it was subsidized or not as i cannot see any marking on the body of the phone nor their is any operator logo at the startup but i think that would be because i performed the hard reset.
Im not that familiar with simlocks, but perhaps a bump would help to find others that might be. I would think that it would have some kind of carrier info at boot, but then again i guess im only used to US devices... In about phone, the imei is listed, which matches the sticker inside the battery cover? And it is not a generic imei?

the IMEi obtained from *#06# is same as the sticker behind the battery apart from one last (or two) digits which i think are the IMEI SV. I am assuming its not a generic IMEI. Also the sticker is unbranded, i dont know if service provider mark the stickers or not.
Stepping back and looking at the first couple posts of each thread, as well as yours, "tried the *#7465625# which returns with 'Not registered on network'" looks like the phone is NOT simlocked... What do you mean by "the phone wouldn't accept a sim"? It would not read it? Have you tried to send sms or a call? Or is it just data that does not work?
Hi dude I had the same problem and I downloaded the play store app Galaxysim unlock. It's from chain fire I think, and it's free. But in order to unlock all the features and what not, then one has to pay. Hope this helps.

The "phone not registered on network" also gave me the impression that it was not simlocked nor does it have any operator branding. But when i inserted the sim it would not connect to the operator and dialing *#7465625# would return the same message, i have tried both 3 and orange sims. This is what is confusing me. I also saw a thread on XDA checking your phones IMEI against blocked or stolen IMEIs and no red flags their either so i am assuming its not stolen phone which my friend bought.
If not simlock what could it be.
Have you checked apn settings, to see if they show up when you insert the sim? Honestly, I dont know how much help I could really offer, since this is uncharted territory for me, but again, maybe a bump and somebody will see this.. Have you tried to PM Odia? He was in the first thread you linked, offering help for people with sim lock problems, even though this doesn't seem to be that. He seems to know alot more than me, that's for sure!
Bought phone that was pin locked .
Surely the seller would have the Pin or unlock it before sale .
Sim / network locked problems .
This has all the appearance of a stolen phone ..
Hard reset will not remove operator logo it is more like the a previous user has flashed a stock rom on it .

So you bought a phone used that had a passcode protecting it that you removed by wiping the phone and can't get it to register on the network. Why would anyone buy a phone that is pass code protected and the seller didn't know the pass code? It would seem you have a stolen or lost phone that has been imei barred by the networks to prevent criminals profiting on crime. Take it to your local police station, they can tell you if it is stolen property

Guess i was overlooking the main evidence: buying a phone that is still code locked. But it brings up another point: Can a phone actually be 'turned off' or barred from the networks?

In the UK it can yes, once the imei is blacklisted it can never connect to any UK network. Unfortunately though it can still be used outside the UK but I think there is some progress being made on countries sharing blacklist databases

I started to look this up for US circumstances. It seems that our carriers cannot lock it down, nor can they track it. I actually read that they expect the consumer to be in charge of evidence gathering, such as setting up a tracking app, acquiring carrier records for usage after the device is missing, and taking this info to your local police, who probably know much less and can do much less. Guess they figure its finders keepers, idk.

Like i mentioned in my first post, its not my phone, though i am not expert in android but this doesnt mean i would be stupid enough to buy a phone that is locked and shows signs of a stolen phone.
Secondly, i had the same suspicion that this phone was either lost or stolen, the guy who bought it told me that the seller told him this phone was a taken from original owner instead of money owed so the original owner must have got this one blocked.
I checked on multiple websites and none of them flagged the IMEI as reported stolen or blocked. Are these websites unreliable or update after a long time.
Due to the new revelations of how this phone was acquired, i will no longer offer any assistance. In my mind, this phone qualifies as stolen.

The only sure way is to contact the network that blocked the phone .
Simlocked the network that the phone is locked to will unlock .Test is by putting the original network sim in the phone .
I would pass this information on to the owner and then stay clear of this phone .

HELP!! GS4 Factory Unlock Problem!!!

So back in febuary I went from ATT to T-Mobile. With a galaxy s4 ATT provided me an unlock pin popped in my tmobile sim and it was unlocked. Later I had to send in my phone because my camera was malfunctioning.. I asked the rep before sending in my device if I will lose my unlock.. They said no. They repaired the phone.. Replaced the camera and PBA (motherboard) because it was also power cycling. So when I got the phone back I popped in my T-Mobile Sim and it was asking me to enter in the unlock pin.. Luckily I had the same unlock pin from febuary I entered that in and nothing happened I tried it again nothing. so I called Samsung and they said I need to call att and request a new unlock.. Called att requested a new unlock and they provided me with the same unlock pin like the first time. and they said only one unlock pin can be assigned to one IMEI number. called Samsung back and said they can't do anything which is B.S... just paid for this phone.. anyways now my phone is acting up again.. Running slow.. Some of the apps show "unavailable" or not responding. I went to the service menu by doing the *#0011# to try doing an unlock another way but it won't work for me.. one thing I caught was the IMEI CERTI: NA.. Idk if tht has something to do with it? any one have any tips? Or that can help?
Is there any way to confirm that the IMEI is the same? It's possible they might have had to swap out the motherboard if it was easier. Check to see if all the #s match between the sticker behind the battery, in the Settings, and when you dial *#06# then see if that's what ATT has on record.

Thanks for your reply... I triple checked the IMEI #'s and they are exactly the same.. behind the battery.. settings and dialing all the same exact IMEI prior to sending in the UNIT for repair.. what strikes me the most is trying to do the unlock by going into the service mode and it says IMEI CERTI: NA

Hmm. I wondering if they didn't swap the motherboard and write your IMEI to it, but for some reason it didn't transfer the whole EFS (not just the folder, but the stuff in the modem too) contents which include the IMEI Certificate. If that didn't transfer over or have the right permissions then that could explain it... Haven't had to deal with an issue like that though, so can't really say.
You're probably better served maybe asking some questions @ forum.gsmhosting.com as they deal with issues like this more often than most people on XDA. Either way, you're in for a tough fix if that is what happened because not many people know much about this since it is a fairly rare issue.

I was wondering that too.. I mean could that be the problem that the IMEI CERTI says : NA? I actually sent my phone back again today.. i wrote a letter along with it explaining my whole situation actually attached a picture of that service mode so they know. I also posted onto gsmhosting.

[Q] SGH-I527 no calls in or out but

What's up fellers! Been gone a long time and know I am back. I got a deal on a I527 and found out the guy used a Metro-PCS sim. I didn't realize this until after I put my SIM in and saw ATT. I didn't see that when he had his SIM in there.
I read the 5 or 6 posts on not being able to make or take a call from a TMOBILE setup but since this may be a little different I thought I would post and give it a shot.
My symptoms are no calls (does nothing then emits a single beep then hangs up). Does the same when dialing out. 4G and everything else works 100% Phone is fast boots quick charges fast no complaints anywhere except the stinking call issue.
I used KIES to reload the stock ROM. Took about 20 minutes and completed. Still no calls. Here are the details
Phone has the ATT logo on back, says SGH-i527, has I527UCUAMK2 all 3 places. I talked to ATT customer service and they said the IMEI points to a SGHNM819N. But nothing on the phone indicate metro PCS.
I use to hack back in the ATT Tilt days. Not anymore. I had a small stroke and can't do all this complex stuff anymore. If someone points me in the right direction I can follow instructions but it seems to have gotten a lot more cumbersome to do these days.
All I am looking for is bone stock reset where everything works. I can wait for KitKat to come out so I would like a clean fix.
My sim is a ATT. The service agent online assured me the SIM was fine. My old phone was a Skyrocket that got wet. So the MEGA needed a smaller SIM. I picked it up today and swapped phones.
Thanks for any help and I am willing to pay for someone's quick help. I use the phone for work and right now I am pinched.

I had a similar experience when I bought a used mega, picked up full signal, eveything worked except that I couldn't make or receive calls, I just got a single beep. I even went to an at&t store and got a new sim card, still didn't work.
The guy who helped me at the store said the sim tray was bad, made it sound like it was a common. Issue. gave me the number to the warranty dept, said they might cover it. I called them told them what happened and what the rep told me at the store.
They sent me a replacement at no charge.
my phone done that when my imei was replaced with a galaxy s4's imei. I finially found a guy that put the imei from another i527 into my phone, he also replaced that sticker behind the battery from the mega he used to fix mine so everything matches

I took a look and sure enough the IMEI on the phone is different than the sticker in the back. I googled about 6 different IMEI sites US and EU based and checked out both numbers. Every single site says both comeback good. Nothing stolen or odd. A couple of site said not locked. I would like to have matching IMEI numbers. I would like the one used on the label. How hard is it to get rid of the one on the phone and make it match the label.
I don't think ATT will let me swap this out for a new one. I am not the original owner and there is no insurance on it.
Thanks

I sent you a private message so you can have it taken care of the right way and don't get messed around like I did my first time around

I wasn't the original owner and didn't have insurance, just had service with at&t. The phone hasn't been out for a year, so it's under warranty unless something shady was done to it. In my case the numbers all matched.
