[Q]

Hi Guys,
I'm from the UK. I've previously owned a IPhone and I decided to try out Android and I love it. So I then purchased a Samsung Galaxy Note 2 from a local phone shop. I bought the phone brand new and I was the first one to open the seals.
I had the phone for 2 days and today I was getting a message saying mobile network unavailable, emergency calls only, so I restarted the phone and that didn't fix the issue. I then decided to try my friends sim card and that didn't work, so I came to the conclusion that the phone is blocked or blacklisted or reported stolen.
So I went for a trip to the phone shop where I bought it from. The manager tried another sim card and still it wouldn't make a phone call. The manager said he would flash the phone and do a factory reset. So I was waiting for about 45 mins and he came back and the phone had SuperSu installed.
What is SuperSu all about?
is it a illegal software?
Thanks

SuperSu is there when the phone is rooted. I suppose the guy has the phone rooted.

A Heppieboeddah says, the phone has been rooted and while there is nothing illegal or wrong with that (most of us on XDA do it as soon as we get a new phone so we can remove bloatware, install custom ROMs etc), it's not something I would expect a legit phone shop to do as arepair.
I would ask for a refund as it sounds like the IMEI has been blocked, usually meaning it has been reported lost or stolen like you say. Even if it hasn't the phone isn't fit for purpose so you're well within your rights to request a full refund.
Then go buy a new phone from Carphone Warehouse or Phones4U etc, somewhere reputable.
EDIT: I wrote my initial reply on the assumption that you haven't modified the phone in any way and it is 100% stock, but I should have asked first, have you done anything to the phone... like installing custom ROMs? Is so then SU is just part of the rooting process and it may be that you have done something to cause the problem yourself. It would also mean that if you do need to return the phone then you will need to follow certain steps to return it to an unmodified state. Talk us through what, if anything, you have done since buying the phone.

Hi, the phone is stock, I didn't install any custom roms or software. As I was new to Android, I wasn't too sure about rooting.
But I don't understand why he put SuperSu on the phone.

SuperSU is part of the rooting process like CitizenLee said take phone back demand a refund and go to somewhere reputable and buy a Note 2

curious. after this "repair" the bloke did, could you then make phone calls?
i dont suppose you looked in the settings, about phone, status and noticed if you still had an imei number did you? before and after the "repair"
regardless, i agree with the previous posts and would definitely take it back, get a refund and get one from a known phone shop.

Unlocked GSM Galaxy Nexus - No signal al all

Hello,
A bit about my Nexus: Bought it online, it's the Domoco version, unlocked, rooted and been using just fine with many custom ROMs.
So yesterday morning, I was talking on the phone with a friend without any problem. After hanging up for a few hours, when I was about to call someone else, I realized my phone didn't have any signal at all. And it has been like that until now, about 48 hours.
It happened so suddenly without any warning. The phone has never been dropped and everything else working just fine.
So here's what I have tried:
- Restart the phone (multiple times)
- Batter pull (multiple times)
- Factory reset the phone (multiple times)
- Wipe cache and dalvik cache in CWM (multiple times)
- Downloaded SetCPU and set the minimum to 700Mhz (instead of 350Mhz)
- Reflash the ROM and tried with other Custom ROMs (I tried Xenon, Xylon, PA, and Carbon ROMs)
- Reflash the Radio and tried with other Radios too (I tried UILH1, XXLH1, SC04DOMLE3 and some others ...)
- I also went to Tmobile and request a new sim card - same problem.
- I borrowed a sim card from another Tmobile customer to try it on my phone - no signal - but the sim card works just fine on his phone.
I ran out of thing to try and I dont understand what happened ... anyone has an idea or something else for me to try ?
Anyone experience this before ?

Welcome too my hell. I have a playstore one now but my first Gnex was an international one and it has this same issue. Its a PCB problem a warranty would fix. I'm near Chicago and a few people have told me there is an electrical engineer downtown that fixes stuff like this. I don't have a price but I think something like this is your only option. Mine sadly is still a battery charger:thumbdown:

I know it sounds stupid, but have you tried toggling airplane mode? I run into the occasional loss of signal when im at work [fair to weak signal in the big metal box], and a reboot is the only thing that fixes it for me. Mines a play store model.

Ah yes, I actually did try that too but forgot to mention. I tried toggle airplane mode on and off, also the 2G only mode on and off. But it didn't help with anything.
Thanks for the suggestion.

So I guess I have to look for an electrician then, cause I have this phone just a little bit over a year so warranty is a no go for me.
Thanks for the idea.
PS: anyone else has more option for me ? I just wondered if I have bricked my phone ... cause I flashed lots of diff. ROMs to try out but never gotten a bricked phone before, could this be a bricked phone ?

Bricked refers to a phone that does what a brick does: nothing. It doesn't boot, it does not light or attempt to boot, it does nothing. This is a signal issue..I have no prior experience with docomo, but this thread came up on search: http://forum.xda-developers.com/showthread.php?t=1574018, maybe it'd be helpful. Have you converted it to yakju or takju and tried a google factory image?
And this: http://forum.xda-developers.com/showthread.php?t=1554150. If it is a circuit board, it kinda looks like s.o.l., and im sad to say that to you.

I wanted to let you know that I experienced the same issue. I bought the unlocked Docomo Galaxy Nexus, and had it working fine on T-Mobile for half a year, and then suddenly had no signal on Tuesday. Nothing I did - factory reset, battery in and out, sim card in and out - could fix it. Have you tried using different sim cards in your phone to see what works and what doesn't?
I figured out that my phone will accept AT&T, and actually does connect to T-Mobile while roaming (I used an international sim card). But, my phone will say "Cannot find mobile network" when any T-Mobile sim card is inserted.

I also have the same problem with the docomo phone. ATT Sim card works. Tried other's T-mobile sim cards and it doesn't work. I wonder if somehow the IMEI has been blocked by T-mobile.

I know others who bought their GNEX through the Play Store and those work just fine with T-mobile. I tried their sim cards in my phone and it doesn't work. I don't think T-mobile is intentionally blocking the docomo phones, because I'm getting T-mobile through roaming, when I use an international sim. My guess is they're doing something to the cell network that just somehow leaves our configuration out. Hopefully it's temporary, but who knows.
Worse case, I'll just purchase a Nexus 4, because I love 4G data for just $30/month with T-mobile. Anyone else got suggestions?

Alright, update on this and there' good news. I called Tmobile and they said my IMEI is actually Blocked. The reason, according to him, is that Tmobile usually sweep the network to clean up all "un-supported" devices, so my device is apparently one of them and therefore got blocked about 2 days ago.
So he said for this, he needs to escalate it to business support and they surely can unblock it for me, but I have to wait until Monday since they don't work on weekend. But well, that's surely a good news. phewwwwwwwwwwwwww !!!
So to all of you guys who are in the same situation, make sure you call Tmobile first before flashing crazy like I did LOL.
Thanks for all the help.

I'd love to know if you are able to get this unblocked and working as I have the same problem as of Tuesday. I was traveling and went into a TMO store, and they told me it was NOT IMEI blocked. In fact they looked at the IMEI and read the page and said 'it was not eligible for blocking'.

I called TMO to see if my phone is IMEI blocked, and through three levels of support the universal answer was no. I'm now fully confused because if it's a hardware issue, why did several people all have the same problem all on Tuesday. For those others who are having issues, can you see the TMO network but not connect to it? That's what I have, I can see TMO and AT&T but haven't been able to connect to either one since Tuesday.

I'll call up T-Mobile tomorrow and ask if they IMEI blocked my device. I had them reset my signal and give me a new SIM card, but didn't realize it could have been IMEI blocked. I'll give them a call on Monday and let you know what the result is. Maybe it won't be too late to cancel my order on that Nexus 4...

I'm quite confused. I've been told last Thursday in a TMO store and with tech support that I didn't have an IMEI block, and the same with three reps tonight. I know the Sim Card is good, and so I'm being told its a hardware issue. However, several of the same phones had the same issue on the same day, so I can't buy it's a hardware issue. Has anyone with this issue flashed a new or different radio into the phone, either before or after the service loss? I have not, running it as it came out of the box.

I just got off the phone with T-Mobile Support, and they told me the device is not blocked. The reason is that T-Mobile cannot block or unblock devices that are not registered to T-Mobile. So I'm back to square one on this.

chowabbajack - When did you first have a problem, last Tuesday? Did you prior to that do any flashing or radio changes to the phone?
We're in the same spot....

That makes me think its something to do with the radio software, because I am the same the problem overall doesn't seem as large as the number of phones I perceive were bought on the Docomo deal.

Ive been using the docomo version of the nexus as well on tmobile for almost a year and it was since last tuesday when it no longer recieved any singal. with some digging around and too many phone calls, I found that the imei number on the phone is not the same as the one under the battery. i have the generic 004999010640000 imei right now and it not sure how i got it. as i bought it unlocked.
what i have tried:
reboot, battery plug, reinsert sim, factory reset, root and flash, got a new sim card, relocked, unlocked
sim card works on other phones.
also i have called tmobile and samsung endlessly and this is what i got:
tmobile cannot unblock the imei since it is not from them.
samsung is redirecting me to their japan branch.
docomo i cannot reach.
my phone before last tuesday:
unrooted stock 4.2.1
been testing different things to see if there is any way to restore the imei
also using root explorer, i cannot find my efs folder....

I've got the same problem since last Tuesday with my GNex and T-Mobile.
Mine is not from docomo though, but the French phone provider SFR, unlocked through FDocomo apk.
Rooted phone, running 4.2.1., no changes whatsoever in the past month and it worked fine until Tuesday, so I don't think I'm responsible for having no signal.
Honestly, I am relieved to see we are quite a few to have this problem, and also very pissed at T-Mobile for causing all this. What should be the next step then? Is there any chances they fix the issue quickly? If not, I might just go to the competition. I've tried AT&T sim cards and they work fine.

I have the exact same generic IMEI number as you, which does not match the number under the battery. I'm not liking the news that you did flash and still no go. I'm a novice at this stuff so please keep us posted.

[Q] SM-N900T, IMEI Cert Fail help

To make a long story short, I bought a T-Mobile unlocked Note 3 off of Swappa, and after three tries I finally got one that didn't have mismatching IMEI numbers, or one that got blacklisted like 5 days after I activated it. Anyway. This newest one was activated and fine until I got home and I did the OTA updates. Now it is saying that my "IMEI Cert: FAIL, -4" when I hit the *#0011# code; resulting in my loss of service. I have been looking all over the internet for a fix for this, and I can't find anything except for other people with this issue, and websites with poor English saying to pay them to fix it. Does anyone have any real info?

A quick Google suggests that using Odin to flash a stock ROM might fix it. I would do a full factory reset first as well. Get things back to base stock, as much as possible.
I seem to recall that some issues with EFS backup/restore in custom recoveries early on were fixed by wiping the EFS partition and rebooting. Apparently the modem firmware has a way to rebuild it on N3. For details, search the general forum and/or development forum. I don't recall details, just some talk about it working as a way to fix devices that got messed up. Don't even ask here about changing IMEI or other illegal options. They are not allowed on XDA, if they are even possible.
I can't believe you went through 3 bad phones. One would have been enough for me. I simply don't buy used phones online anymore. It's not worth the bother to me. I buy direct from TMO as I can make them fix it if they give me a bad one. Sucks, but since they can blacklist any time, and leave you hanging, I want to be sure I have a reputable place to go to get it replaced if that happens. I hope you get yours working again.

This may be a little bit late, but I just discovered that I could fix mine with the exact same issue by flashing a Jelly Bean modem for my model.
Under any firmware on KK or LP, it would Certi: Fail, as soon as I flashed a JB modem, it worked again and passed.

Confused why my LG G4 can't unlock..? It's a new unactivated warranty replacement

I've tried a few services online and none of them can unlock (sim/network) my LG G4 H812 (Canada). Abit long story, but I bought this new from WIND a few months ago, but switched to another carrier (Mobilicity) recently and unlocked it fine. But soon, the G4 had issues so I received a warranty replacement with a different IMEI. During this warranty process, the service center asked who the original provider was, so I said "WIND". I assume that meant that the replacement was locked to WIND again.
OK, np I thought, I would just get the replacement and unlock it again. But for some reason no one is able to unlock it. Is it because this new phone has never been activated with any carrier..? How am i supposed to do it? I no longer have the WIND sim either.
Thanks,

I'm having this exact same issue. My LG G4 was bought brand new from Wind about a year ago, but was sent in for repair through Wind's warranty service. I had the bootlooping issue, so my phone received a new motherboard, and subsequently a new IMEI. For resale purposes, I tried to SIM unlock the phone through multiple third-party services with no luck. I then tried asking Wind for the code directly, which they didn't have (I assume this is because it is a brand new IMEI), so Wind told me they'd request a code directly from LG. I received the unlock code a few days later, but even that code doesn't work. I'm honestly stumped, and my phone's now down to only 2 SIM unlock attempts remaining. Did you ever end up having any success with your phone? Were you eventually able to get it unlocked?

What issue did you have with it to need it repaired in the first place? Since the unlock code that I received from LG directly didn't work for me, I'm a little hesitant about using one of my last two unlock attempts on cellunlocker.net, a third-party service. BUT, seeing as they worked out for you, I'm somewhat hopeful.

Question T-Mobile Network Issue

Hello
Hopefully someone here can point me in the right direction for help or assist.
I purchased a unlocked Galaxy Z Fold3 off of Swappa.com. Ive purchased many of phone off this site and had no issues including this Fold3. When I got the phone i placed my T-Mobile sim in the phone and all was fine since the phone was unlocked. When T-Mobile pushed the Android 12 update out we all know it caused issues with the phones network. Since i did not purchase the phone from T-Mobile i sent my phone to Samsung so they could fix the issue. Since they knew of the issue with T-Mobile they replaced the motherboard of the phone. Well that sim locked the phone to the original carrier which i found out was Spectrum Mobile. Spectrum states they cannot unlock the phone because they cannot see the IMEI on their network. T-Mobile sees the IMEI on their network from when i used the phone before the update, but they stated that since the original carrier is Spectrum, they have to unlock the phone. Samsung states that one or the other will have to unlock the device because they do not have carrier unlock codes even though they replaced the motherboard which cause the phone to lock again. After weeks of the back and forth i paid a site to give me a unlock code for the phone via Spectrum Mobile. the code they sent did not work and they refunded me my money. But now im stuck with a brick unless i get a Spectrum Mobile account. The phone works fine on their network but i refuse to get their internet service so i can get a mobile account just to use the phone.
Anyone have any advice as to how i can get the phone unlocked again? I reached out to the person i purchased the device from and they didnt have the unlock code. Also the IMEI is clean because Samsung, Spectrum, and T-Mobile checked it.

Right now, you can either pay for an unlocking service or, and this is the REALLY hard part, wait until Spectrum's IMEI Database is updated with the new IMEI for your device. This will come from Samsung when they Sync, but no telling how often that is.
The bad thing is, it can take weeks or a month or more. No one knows.
If you are in need RIGHT NOW, I would look for a good Unlock Service and pay them, but it can also take a while with how new these phones are.

I have an Unlocked Fold 3 also now using the T-Mobile network and keep experiencing network connectivity issues. In placed where I used to get good 5G signal now I only get LTE and sometimes my data connection drops to H or H+, sometimes just R for roaming.
So they believe the Android 12 update killed the Motherboard in our phones for T-Mobile? Also how long did it take to get your phone back from Samsung after the repair?

Samsung sent me a shipping label that was two day shiping to them. it took about a week or so to get back. Yes, something with the T-Mobile Android 12 update caused an issue where Samsung has been replacing the mother board of the phones. I found out when i was looking on T-Mobiles forums and a person stated that is what fixed theres. So i contacted Samsung and told them about the Andorid 12 update causing the issue and they had me send it in since they knew of the issue.

@Talderon ive tried two unlock companies so far and neither have been able to unlock the phone. The person i bought it from wants me to mail it back so they can unlock it with a pc. Not going to happen so i won't get it back LOL. I think im just going to get on a friends Spectrum Mobile account and wait 30 so they can unlock it. Think thats my only choice.

If I'm on Google Fi (Which is T-Mobile) is it better for me to get the T-Mobile version of the phone off of Swappa/eBay so I don't run into these issues?

Just buy the samsung unlocked version and then flash the t mobile rom to I have the u1 one version I never had any issues with using t mobile on my z fold 3 and you need the rom bc its helps with towers bc I was using verzion rom on t mobile and I didn't get all the service or 5g uc always buy us unlocked version never buy carrier ones bc it's just easier to flash the rom you need than buy the carrier one bc it's can be relocked at any time bc when I bought t mobile version s21 it's locked the phone so beware

Hello
Hopefully someone here can point me in the right direction for help or assist.
I purchased a unlocked Galaxy Z Fold3 off of Swappa.com. Ive purchased many of phone off this site and had no issues including this Fold3. When I got the phone i placed my T-Mobile sim in the phone and all was fine since the phone was unlocked. When T-Mobile pushed the Android 12 update out we all know it caused issues with the phones network. Since i did not purchase the phone from T-Mobile i sent my phone to Samsung so they could fix the issue. Since they knew of the issue with T-Mobile they replaced the motherboard of the phone. Well that sim locked the phone to the original carrier which i found out was Spectrum Mobile. Spectrum states they cannot unlock the phone because they cannot see the IMEI on their network. T-Mobile sees the IMEI on their network from when i used the phone before the update, but they stated that since the original carrier is Spectrum, they have to unlock the phone. Samsung states that one or the other will have to unlock the device because they do not have carrier unlock codes even though they replaced the motherboard which cause the phone to lock again. After weeks of the back and forth i paid a site to give me a unlock code for the phone via Spectrum Mobile. the code they sent did not work and they refunded me my money. But now im stuck with a brick unless i get a Spectrum Mobile account. The phone works fine on their network but i refuse to get their internet service so i can get a mobile account just to use the phone.
Anyone have any advice as to how i can get the phone unlocked again? I reached out to the person i purchased the device from and they didnt have the unlock code. Also the IMEI is clean because Samsung, Spectrum, and T-Mobile checked it.

See you shouldn't buy carrier phones don't do that bc you always have issues and it's hard to find unlocking service just resell the phone and just buy you unlocked us version off ebay and then flash t mobile rom and you be good and then you don't never have to worry about having a brick
