i337M Abrupt Signal Loss - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi everyone,
So about five days ago I was in the middle of using my Galaxy S4 (I think I was playing a game or something) and all of the sudden my cellular signal dropped out completely—from 4 bars to zero with a little X in it. There it's remained ever since.
My first thought was that I ought to reboot the thing and see if that would solve anything. The answer was no.
My second thought was that maybe my contract was up (as that was due to happen this month), and rather than auto-renewing, they kicked me off. Weird, but possible. But that's not it: I phoned up my provider and they said that all systems are go, there are no outages, your account is active for a week still, and even past that contract expiry I'll just get bumped to month-to-month and never experience a blip in service. So that's not it.
So then I put my SIM in another unlocked phone, and lo-and-behold, it connects just fine. So clearly the problem is with my phone.
My i337M is running Liquid Smooth 2.9 and KToonSez' kernel. I decided to make a nandroid and flash back to stock ROM/kernel. Still I could not connect to the network.
I can only think of two potential problems. First, I unlocked the phone myself via FastGSM.com's tethered USB method. It was a Bell-locked phone, and I'm on Rogers. This was accomplished back in July, and since then, there haven't been any issues to speak of (i.e., the unlock worked flawlessly). I tried to see if those unlocks ever expire, and couldn't find any reason why they ought to. I personally don't think it's that, but I mention it out of interest in being thorough.
Second, I messed around with my phones NVData a few weeks back to enable the AWS network via this method. I didn't experience any signal problems after doing so. Again I mention this out of interests of being thorough. Could that have had something to do with it? I suppose I could try flashing back my original NVData, but honestly I don't see why that would suddenly kick in now since I did it weeks ago originally.
Any thoughts? This is really bizarre, and it sucks being without connection.
I was also thinking of flashing back to stock and going to a Bell shop to see what happens when I put a tester SIM in.

It sounds to me like it's hardware related. Don't see anything you've done that would have caused it. I'd flash back to stock and if it still persists I'd file a warranty claim.

Hi, thanks for your reply.
An additional thought's occurred to me: I lost signal at or about the same day I setup Android Device Manager to allow for remote lock/wipe directly from Google. That couldn't possibly be responsible for signal loss, could it...?
Currently flashing back to stock, and I'll unroot/restore kernel/restore NVData and make it look factory, and see what the store says about it. Hopefully I don't have to pay for another unlock at some point.

Okay, this is very messed up. Nobody has any idea why my phone isn't getting signal. I can scan for networks and everything shows up, but in any case with any SIM it says "unable to connect to network". It doesn't matter what ROM I'm on. I flashed back to stock and updated to latest using KIES of all things, which found a firmware/modem/baseband update, and still no dice. I don't know what to do with this thing except take it to an unlocking store that might be able to figure something out for me, but it'll cost me. This is messed, I've never had to get someone else to look at my tech for me.

Okay, so the situation is that it most probably is a hardware failure related to the radio.
I am a Rogers customer who bought the phone from a guy from CraigsList who apparently got it from Bell. I went into Bell and explained the situation, and they scanned the IMEI and printed me out a proof of purchase of the guy's name and told me I should take that to the Bell service centre, and it doesn't matter if I'm not the guy. I also had them check to see if he reported the phone stolen; it turns out he did not—though it should be known that if he had done so, then that could have very well been the reason I wasn't getting signal from anyone, as all providers across Canada apparently share their blacklists with one another now (including the little guys like Wind/Mobilicity).
So now I am in the process of making it look like it's never ever been hacked before: I shall restore my NVData, unroot, and update everything using KIES, and then perform a factory data reset. I'm also on the hunt to figure out what the heck the "flash counter" is and whether or not I need to reset that, but perhaps since mine is the i337M Canadian variant, I don't need to worry about that. (Any advice on restoring my phone to factory condition would be welcome, thanks.)
Edit: Figured out TriangleAway and everything associated. I'm all stock now and ready to bring it back to the factory.

MAJOR UPDATE: PROBLEM IDENTIFIED
So I got my phone back from the factory today. They reported that everything is 100% a-ok on the hardware/software side of things. The radio IC is NOT blown as was suspected.
You know what they said? The problem is on the network. I have a story to tell that I think people should hear, as I've learned something very valuable today and people need to learn this lest they get conned themselves.
Today I phoned in Rogers again, armed with new information, to ask what's up. They ran the IMEI number, and this time... it's come up on the blacklist.
It wasn't there last week. In fact, it wasn't even there an hour ago. It actually only appeared there as the clock ticked past midnight Eastern time... as that is EXACTLY 90 days from when the phone was reported missing. It took them a long time to track down this information.
To reiterate, I did not steal the phone. I bought it from a guy on Craigslist who had it brand new in box with the screen-protector sticker still on the front of it. I checked it out, tried it, and unlocked it myself and have been using it since July without issue, until a week ago.
There is the trouble of, why now? Why only now does the IMEI come up blocked? What the senior rep at Rogers thinks happened was that the guy had it delivered to his house, didn't sign for it, kept it in box, reported it as "undelivered", and flipped it to me for cash. Insurance has meanwhile hooked him up with a new phone, and the factory kept my phone in the "we're looking for it" pile for the requisite 90 days, after which they officially publish its IMEI as "blacklisted". That would explain why it worked for a while but doesn't now; and this 90-day TO THE DAY period is the same for Rogers as it is for AT&T apparently (which is where the rep used to work for 10+ years).
I am in possession of stolen property. I've little hope of recuperating my losses. I've been advised to file a police report, and I think I will actually, given that I've got a receipt with the "anonymous" guy from Craigslist's name on it which I had printed out from Bell after they scanned the IMEI number for my factory warranty receipt. This phone will officially never work in Canada, as there is no way for it to be removed from the blacklist. I've been very unfortunate in this case, and it's a real shame.
People should take note: If buying a phone, ALWAYS do it in-store and have the IMEI number run first to check and see if it's on the blacklist. Next, have the phone transferred into your name so that the IMEI and you are officially linked, and the guy can't report his gear stolen or lost. That should suffice in most cases... except in the case of insurance fraud, which is my case, where there is a 90-day delay period in the IMEI number being added to the blacklist (which is why it didn't come up on the blacklist last week when I had the Bell rep run it in-store for me). Another point of interest is that in my case, I found it was possible to lose service BEFORE the number is on the blacklist—assuming the Bell guy didn't run the number wrong last week.
So f**k me. All I can do is try to hack the number, I guess, or find a way to spoof the IMEI.
Edit: Unf***ing believeable—I somehow reenabled data and texting by messing around with QPST. Calls still not happening, though.

IMEI issue on a USA T-mobile MDA

Hi,
I just bought a MDA off ebay and the phone works great!
BUT the problem is IMEI numbers dont match ANYWHERE!!
Box, Back of phone and *#06# They are 3 different #'s
I can still make and recieve calls and go on the net.. phones works properly.
Is there anyway some1 could have changed the IMEI? Or is there a Rom flash that could have done this?
OR could a Unlock have altered the IMEI?
And is there a way i can change the IMEI to the same one as the one on the back of my phone?
The Seller has agreed to refund my money, but I want to exercise all my options b4 I return it. Bc the price was actually great!
Any help will be appreciated.
Thanks in Adv!
Brit.
:thumbup:
PS i did search for this issue and did come accross some good threads, but there was alot of "THIS IS ILLEGAL" i know this so please post somthing meaningful...
Your best bet is to get your money back. At best the phone was serviced and the guts placed inside the wrong case by accident (which would explain 3 different IMEI) but at worst there could be something hinky in the phone's history that will come back to bite you as the current owner.
I wouldn't worry about it.
1) The phone works
2) You know the phone's actual IMEI
That's all there is to it. Don't worry about it.
both of you bring up a good point.
I am leaning towards keeping theh thing b/c of the price i paid for it b/c of a mislabeling of the auction. It was a super low price..
I will check to see if the guts were changed, there probably will be a sign if the casing was opened.
Can you give signs to look for tampering?
Second, I read were some1's IMEI changed b.c of a Unlock could this have happend to my MDA?
Thanks for you replies agian!
HTC (or T-Mobile Warranty) might me able to confirm if any (or all) of the IMEIs you have are from serviced phones.
As for the Unlock changing the IMEI, I know one user reported it but I seriously the validity of their story.
I've CID unlocked 5 HTC Phones (3 BlueAngels, 2 Wizards) and SIM unlocked them also with the IMEI never being changed.
Just remember though, if there is something hinky and the phone is hot you can lose the phone and never see your money.
I would imagine that if the phone was put up for sale, sold, shipped, turned on and found to work and it is hot, the heat has probably cooled considerably. Or, in other words, if it was going to be banned by the network, I would think it would have already happened. As far as unlocking changing the IMEI, I second the above. Few things are impossible but a simple unlocking changing the IMEI has to be close. If it was my phone, I'd first look for some obvious sign of tampering. Crooks aren't very smart (they are crooks, after all) so it shouldn't be hard to find. If nothing jumped out at me, I'd shrug my shoulders and call it mine.
Cool, I will call HTC.
I just called Tmobile and they said that they dont BAN phones, they just ban simcards. but I doubt they would admit the truth.
the phone working is a Positive sign to me.
But I will call HTC and confirm. ALSO I will Call Paypal and see if i have any kind of warranty to buying a stolen item.
if all else fails i will return the phone to the seller.
Brittany
the IMEI should look exactly like the IMEI on the back of the phone rite? not shorter or longer?
i will reverify if its' shorter or something. b/c i read some where about a 17 and 15 digits are needed.
ALSO say if my MDA was stock right out of the box would the phone have these 4 lines on the top left corner in red with some numbers and stuff.. possibly rom info and model info?
Usually the stickers with IMEI numbers are difficult to forge since it requires a special paper (Nokia at least) and a special kind of file.
Although the theory of mixing boards, cases and boxes is very plausible there's still the chance that the IMEI on the back of the phone is the hot one. You can always try to change back to it (but taking note of the one stored presently in ROM for future use) and see if it gets barred/blocked or you get a visit from the authorities :twisted: In any case, this forum's posts could help to prove your innocence in court (just kidding :lol: )
As for the procedures to achieve it, get back to me via PM
cheers
Well i took it to a local Tmobile store and they exchanged the phone for me. WOOT! WOOT! this was a pure sealed one. so prob solved.. now i just have to do a CID and Sim Unlock and upgrade to the latest rom.
Any recomms? i will try to do my NEWBIE duties and search and learn, if anyone wants to make it easy for me. well hooka sista up!..lol
Brit
Wow! Not bad! If the 2.26 ROM is already on it (I got a new one a couple days ago on warrantee and that was the case), you may want to think twice before changing that. I've been real happy with 2.26 and it's gotten to where the ONLY thing I bother changing in the registry is the glyphcache and menu settings and I uninstall OZ, the DAT MailTrigger thing and the Hotspot login utility. And...bonus time....you don't void the warrantee that mayb prove handy in the future.
Moral of the story.. get 3 old phone, inter change their IMEI (e.g. stickers and box) .. go to different local store to get 3 new phones
So last night i did
1. Sim Unlock
2. CID Unlock
3. installed AIM (wifi friendly)
4. Upgraded the rom to 2.26
5. installed Agile Msnger beta verson
phone's running like butter! Thou after i installed AIM phone RAN really sluggish! but i think it was b/c i put my orig sim card with 150 entirees.
so i rebooted charged the phone to 100% and did the rom upgrade from Tmobile's webiste..
the phone runs like a charm now.. I just need to find a good Instant Messenger software, wiht profile and away msg so my friends to hit me up with a huge txt msg bill..
I came, i read, i learned, i conquered the mda!

Anybody have the 3 Mobile firmware?

I have flashed my three mobile to the latest .184 release, and just before doing this I used flashtools to make a backup. Somewhat stupidly I went ahead and flashed without checking if my backup actually works, I have checked since and it just tells me to unplug and turn on debugging etc (they are both on).
Has anybody got an original three firmware they can upload in case I need it - since doing this I have also noticed problems with wifi tethering so it might need sending back
If no one can help (if anyone can it would still be appreciated), can anyone tell me if it will cause me problems getting my phone repaired.
Although I originally flashed the .184 update uploaded here I have since run a SEUS reinstall so technically the firmware is 100% official SE generic firmware. Will this mean it will be fixed as all they will know is that it is their software on.
I had some worrying news when I asked in a carphone warehouse repair center today, the engineer (I have doubts they actually hire engineers) told me if he finds I have changed the software he is required to inform SE themselves the phone details and have the warranty voided. This was after actually telling him that I had changed it though, and he might have been thinking custom - I also didn't explain the SEUS update that means it is completely official.
Anyone any advice? I definitely have a hardware problem that needs fixing so I am desperate now.
from what I remember the only difference was the bootscreen and the three app and a couple of games I doubt you will have any major problems. I'm pretty sure the main thing they didn't like with debranded firmware was you could set it to just use the Orange network which cost them more money, but now they are 3G only...
With WIFI tethering try changing the name of the hotspot I couldn't get it to connect at all, changed the name and it worked fine.
Thanks for the suggestion, I just tried renaming but it has the same problem. I can connect for 2 minutes then it stops working and needs turning off and on. It is identicle no matter what I do; after using SEUS or restaring the phone. I am pretty sure it is a hardware problem now (it seems unlikely to be software otherwise more people would have this exact problem). I'm also having problem connecting to wifi while out that I didn't notice untill I started using it more.
Ill give it a couple of days to see if anyone gets hold of the three firmware just in case (I don't want to give them a reason to try and screw me around, I like the plan and unlimited internet but their CS is abysmal sometimes), I will just go for it and send it back if not.
How long have you had the phone? I got mine switched over about a week after I got it because the camera had a problem. I have actually in general had some great customer service from them over the last couple of years they even just refunded me £40 of internet data usage because they did not explain it to me properly (One plan didn't start for a month apparently :/).
Good luck though hopefully they will just swap it over if they have some in stock. Make sure you take everything you got back in order to get an exchange.
Just over a week - got it on the 26th. The problem is I upgraded over the phone and had some problems then with overcharging, this is when I found out that the shops don't like dealing with phone customers and would not help me at all. Maybe they will be more accommodating for a hardware problem - or maybe if I refuse to leave until they behave like I am the one paying £40 a month to the company whos shop I am standing in I will get some service (Im actually getting prematurely angry lol).
Ill give the store a go first if I can't find the fw soon.
Thanks,

GT-I9300 Not Registered on Network Problem Solved

Dear All,
I write to inform you that i finally solved my GT-I9300 'Not Registered on Network' problem. I decided to make this official announcement so as to assure others, most especially those who have tried almost all the tricks and steps found on this and other forum on the subject that all hope is not lost.
May be if i shed more lights on the problem which i encountered, and i suppose many other people, you will understand me very well. First, i did the upgrade through Samsung Kies and after the phone rebooted, it lost link to network. I called Samsung and chatted online with the Customer Service, i was asked to send the phone to South Africa where i bought it. I called South Africa and also chatted but they could not understand let alone solve the problem. I headed to XDA and other forum to find solution, I tried all versions of ARIZA Patch, none work. I tried all modified ROM, yet no solution. At one point, the problem became complex. The phone moved from not registering on network to 'Factory Mode'. I followed many other steps, but could not get past restoring it back to User mode. I gave up after a month and bought another phone.
My son shocked me last Friday when he said that it will be his first time of seeing me accepting that some problems cannot be solved. I mused over it and told myself that i will rather destroyed the phone totally than giving him the impression that i cannot solve the problem.
I got out my two computers - Mac and PC and reformatted them all. Installed ODIN and downloaded a 4.3 Stock ROM. I then began searching everywhere for any clue as to what went wrong with the phone. My research is simple; the PHONE could not register simply because the IMEI and Serial Number were wrong. My IMEI and S/N moved from 0000 to unknown. After reinstalling through KIES, it came back from unknown to another wrong numbers.
I finally decided to go inside the phone by activating everything on ODIN and see if i can get the wrong EFS on the phone wiped away and left empty. I repartitioned, wipe EFS, etc. and the only thing the phone did was to move from unknown to another incorrect IMEI and Serial.
Finally, i read on a post that the problem is simply software, so i began searching if it is possible to repartitioned the phone completely and turn it into a toy. I recalled that about ten years ago, i successfully installed Nokia OS on Blackberry through a poorly concerted code designed by a friend. In so far i still have the code, I thought that i could do same with my GT-I9300. It won't work, sadly. But in the process of doing so, i realized that using SRS, i can do so comfortably. With this 20 USD software, i gained control of the internal organs of my phone and started out by wiping out the EFS first and with my EFS Backup, i re-wrote it back on the phone. That done, i expected the phone to work, but sadly it refused to register on network.
Not ready to give up, i went further to see what other options are available to me. I realized that i can actually re-wrote my IMEI and Serial number back to the phone. I tried it and after about an hour and almost three attempt, T-MOBILE surfaced on my phone and the GT-I9300 came back to life.
Altogether, i spent two unbroken days reading and reading and applying one step after another, one procedure after another till i finally got the phone back.
SRS can not only do this, but can take back your contract and locked phone from those shylock and give you your phone. It go inside your phone and show you all the codes that locked you to a particular network, etc. It can remove those useless codes that make your phone patented to a particular country and give you an international version. It can also turn your international version to a local one, if you so desire.
I do not know who designed this software, i however testify to its immense ability to safe you from Samsung's irresponsibility.
I am open to helping others and answering questions on GT-I9300.
I have since been enjoying my phone.
what's the short version of the story?

Going by the last lines, it seems this is the tl;dr version
"SRS can not only do this, but can take back your contract and locked phone from those shylock and give you your phone.

Hi! As i understood i need to get SRS and after?
where is the SRS software ? can you post a link ?

Abnormal factory reset

I just purchased a s5 off craigslist for 350. Thought I did my homework and called Verizon to verify it wasn't lost of stolen. All checked out fine. So went ahead and purchased the phone, bought a sim card and called and activated it through Verizon. That all went find. But during setup of phone I get the abnormal factory reset screen. So I called Verizon, they told me to call Samsung, as I did. They told me to call back with my carrier on the line, again did so. At this point, both told me there's nothing they can do for me. That I needed to contact previous owner, so I did so. I said either give me the info or money back, they quickly said they would give my money back, (great!) we set a time up to meet and they never showed later that night they text me n said they have the info to call them. I did so but she said let me text it to you. Well that was yesterday morning, I've made several contacts to them with no response. So I went to the Web and also went to my brothers (which he is a developer, not a phone developer but he is much more knowledgeable than me). We looked for back doors, but all seem to be patched. I also recreated a Samsung account registering the phone to it, doing a factory reset, still nothing. Tried to flash it to a older version (4.4.4 & 4.4.2). But Odin couldn't get it to pass. I've tried calling the phone & text as its active but nothing shows up. I tried connecting ear phones to it and making the music screen come up, again nothing. I'm out of ideas and out of 350 at this post. hard lesson learned here about buying phones on Craigslist. But I figured I'd post this on here to see if anyone has any other ideas
Sounds like a big ole mess man im not sure if this will help but give it a go http://myandroid.nl/reactivation-lock-solution-for-galaxy-s5/ best of luck
Yeah completely retarded and I'm frustrated with myself for not looking into the phone more.. Unfortunately they have patched the bypass of the link you've posted.
Can you root the phone and install cm 12.1? defo wont nag you about accounts and stuff like that.
The reactivation setting is default on. That's what we believe is stopping Odin from allowing the root/flash to take place
UPDATE:
so after dealing with samsung for many hours, they advsied me to send my phone in. I did so, after receiving it back, the issue was enver fixed. called them back and was advised there was nothing they could do by sending it in (so i wasted my time and money even doing that). now beyond pissed i was advised to take it to best buy and they have a Samsung desk there and could flash it.. (which i attempted to do several weeks ago and they said they couldn't help me). ive tried flashing myself as stated before but had no luck. does anyone have any backdoors/fixes they know? if you don't want it to be publicly known, you can email me just ask for it and ill give you my email.
thanks a bunch, hopefully i can come to some fix

OnePlus 8 T-Mobile Repair Nightmare

Figured I share my repair experience here as OnePlus has set a new low in my book for customer service. Started when I sent my device (unlocked by T-Mobile) for repair last month. I was given the option of repair or replacement but chose repair so I wouldn't have to unlock again. I received it back about a week later but with no documentation as what the repair was (found out through my calles it was a motherboard replacement. I did notice the SN was the same but the IMEI was different. Used it for 3 days and called T-Mobile to have it unlocked but their system now sees my device as a non-T-Mobile phone and they can't unlock it (and they have tried 4 times since Sept 25th). Over the past few weeks I have conferenced on T-Mobile support with OnePlus support in an attempt to get it unlocked and every time I call it's like starting from scratch with OnePlus. Four times now I've been told to wait 24-48 hours so they can hear back from there repair facility, I've made 14 total calls to check status (they have never called me back once). T-Mobile has been absolutely great and were on the phone with OnePlus with me for over an hour. So for know unless a miracle happens I'm stuck with a phone that can't be network unlocked by any carrier. Looks like the repair facility perhaps used a standard motherboard and flashed the T-Mobile firmware on it from what I can determine. If you need service for a T-Mobile device ALWAYS choose a replacement if you have the option)
Rule #1: Never ever choose repair when replace is an option. XDA is rife with people complaining about repair issues with every phone manufacturer. But I think you know that now. Also, I would hardly fault OnePlus in this situation. Its a simple issue of the IMEI not being in the T-Mobile database. Thats not OnePlus' fault. Thats a T-Mobile issue. IT can be added to there database. Verizon does this but for a completely different reason. But ultimately fault is in the eye of the beholder.
Also, to further support my claim think of it this way... T-Mobile (and Verizon) request the bootloader / SIM lock. If you buy the non carrier version from One Plus this would be a mute point. Again, a T-Mobile issue, not OnePlus. If you really want to get technical fault the US Congress for allowing them to lock in the first place. Ok Ok... Way off on a tangent...
Now... Some questions for you...
Have you ran the IMEI against an IMEI check database to see what kind of device it returns as? I would be curious to see. Another way to find out if its a T-Mobile device is to check the IMEI against your last phone. If the first few digits are the same or different will support your claim of the device being different.
Have you tried to tried to toggle the bootloader unlock switch or is it gray'ed out?
Have you tried popping in another carriers SIM just for giggles?
Lastly, have you tried to unlock it yourself by using the built in unlock program in network settings?
If that fails you may want to consider sending it back to OnePlus again for replacement. I can only assume that you do not have insurance? If you do then you may want to check with them about replacement faulting the IMEI as the issue. Might be a hard sell but I'm sure it could be done.

Same situation here, mine was unlocked did a replacement and it was locked and T-Mobile has no record of it. It took me 17 days to get the replacement and every day I checked the status I get told wait 24-48 hours. Now after I got it I'm told every day to wait 3-5 days for an update. Really one plus?
One plus sucks at anything customer service. Can you not do a warranty through tmobile?
Hi, i have the same problem. I was able to unlock my OP8 the moment I bought it. But after sending my OP8 for repair, it was locked when sent back. I got the error "server 255" when I tried to do a permanent unlock.
I contacted Tmobile and they said I need a valid tmobile account, which I don't:
"One of our mobile device unlock requirements is an active T-Mobile account. Since you don't have one you're going to need the get the unlock via a 3rd party company. Our apologies for this."
I have contacted OP 4 times now. They say they'll escalate my problem to the relevant team.
So how did u ppl solve it? Anyone tried the mtd below:

I hate oneplus with a passion I'm 8 months and still going with an issue they keep BS'n me on
Hi, I would like to post an update. After contacting OP support a few times thru chat, they agree to help me talk to Tmobile directly. I told them I can't use the phone, I'm overseas (really, no joke), and I contacted Tmobile but they refused to help.
After waiting for a few days, my IMEI is whitelisted and I was able to unlock the phone. So I guess if you are persistent enough and tell them tt you've exhausted your options, they will help. So I guess they're still nice ppl (kudos to Sophia!)
Hope someone with similar problem can try what I did.
Just wanted to fan the flames that OnePlus is still up to their BS. I sent my phone to repair the back glass after I recovered from unbricking my phone rooting after the Android 13 OTA. When I get it back, after all these warnings signs something was off I realized when I tried to put my unlock_code.bin and it kept failing that they gave me a new motherboard. Luckily I AM a Tmobile customer, but holy heck, what if I was not? Luckily somehow I was able to get in to get the info to request another code to unlock my bootloader even though I'm still carrier locked.

I just had my op8 repaired back with a motherboard replacement so that it can't unlock the sim as I am not a T mobile customer. I used online chat several times and complained about sim-unlock. Finally, after I gave them both old and new imei and strong complain, they unlocked my sim card. Not a good experience, but the result turned out to be good.
