Hi All,
I flashed the Samsung newest 4.1.2 and when I did it I noticed I could not call anyone as no network etc. Since then I have done some digging and found that my imei on the phone under status is different from the one in the back of the phone under the battery. I have read about an app called gsII - repair to try and get it back to normal as it has done some damage to the efs backup file (I think).
I have been flashing for well over a year but have not got a clue how to get my phone working again, can anyone help please??
I have read loads on here but as I am a noob with code etc it looks extremely difficult, so any advice would be great as I have a phone that does not phone at the moment and my wife is doing her nut in as I am away on business and she can't get hold of me...
Thanks in advance, Phil

There are plenty of topics on this for you to read or reply to, no need for creating another one just to get same answers you could have got from the others.
Hello, recently I've been getting a no signal problem with my S2 running SuperNexus ROM. Basically, I have no signal. I have a IMEI (I checked online, and it's legit) and I have a efs folder backed up from when the signal was working.
This happened to me already, and It was fixed by reflashing SuperNexus. Not this time.
How can I get signal back? The phone is unlocked. Shall I restore my old efs? Also, when I search for networks it says "Error while searching for networks".
Please help Any help is appreciated.
THE SOLUTION WAS:
Install https://play.google.com/store/apps/details?id=com.helroz.GSII_Repair&hl=en
Do step 1, and step 2. After step 2, reboot. Problem is fixed.
Either you factory reset & restore or you flash stock.
Are you sure it happened overnight?
Check the supernexus thread to see if this is a known issue.

I checked the supernexus thread, and I didn't find anything. Also, I'm pretty sure it happened overnight. It happened like that the last time too. Also, I kinda want to avoid flashing more stuff. I flashed enough already. Can't be bothered to waste 30+ minutes getting everything configured again in settings.
I put my SIM into another phone, and a different SIM into my phone. On the other phone, I can call and I have signal, so not a SIM problem. Now, this is the stupid part: the other SIM works well on my phone! I get signal and I can call etc. so its not a phone problem.
What is this? So is it just my SIM can't work on my phone? I never saw anything like this! Anyone can help?
Network locked.

What does that mean? And what can I do about it? I tried other SIMs from other networks on my phone, all work fine, and from my network, orange too.
Maybe your SIM is f#@$/d up.
I dunno, if you don't wanna come across these issues flash stock.
Sent from the little guy
I'm gonna try my luck with stock and then flash SuperNexus again. Also, how can my SIM works with other phones, but not with mine anymore? I don't really want to flash stock and then SuperNexus again, because I'm pretty sure it's just gonna come back again, like last time. Last time the solution was simple. I want this to be done and over with. My SIM is 4 years old, so maybe I should go to EE (as that's what orange is called now) and ask for a new SIM? I don't know :/ Also, what did you mean by network lock?
Try galaxy sim unlock just for kicks.
You could also ask for a new SIM, yeah.

I tried Galaxy S2 ulock by chainfire, and it said that the unlock code is a few 0's. Does that mean anything?
I installed a few more unlocking things, and stuff related to it. I installd SGII_Repair, and after r/w mounting efs, I got signal back Such a weird solution! I kinda want to keep this thread going, as I don't know why that happened.... twice. I want to avoid this kind of problem, so I would like to find the source of it. If anyone can say something, that would be awesome.
Your EFS folder was kind of messed up then.
And you're right, it's weird because EFS don't get fu&*%%* up overnight.
Sent from the little guy
The problem is that I don't know how it got messed up xD Might do a totally clean flash, from stock ICS when I get some spare time. And I don't think that it actually was messed up. The first step of the app was to back up current efs. The second one was "force rw mounting on efs folder". I tried the app last time, the time I temporarily lost my IMEI, and it didn't work. So glad it's finally fixed, but I'm scared it will come again
Hey guys,
I've been having a problem recently that i'm rather stumped about, i've been trying to fix it for the past few days, looking pretty much everywhere on the net for a fix but this is pretty much a last resort before i take it to a random shop and have them attempt to fix it.
So basically i had a galaxy S3, it broke and a close friend of mine had one sitting around gathering dust so he gave it to me to use. The problem is that for some reason this phone refuses to get any mobile signal. It connects to my WiFi without issue however it always has no service and says it can only perform emergency calls. At first i figured it may have just been my SIM card so i've tried it with 3 different SIM cards with 3 different network carriers (I've been informed that the phone is definitely network unlocked too) i've tried to manually connect to the network through the mobile network settings but that seems to bring me no luck either. The phone was rooted and whatnot but i've attempted to flash a stock ROM onto it to see if it was a ROM issue but that seems to have done nothing to help. Now i'd consider myself rather tech savvy but i'm a novice when it comes to tinkering with mobiles so any help or advice you guys could give to possibly resolve my issue would be greatly appreciated.
After writing this and performing one last search so that i don't make a complete fool of myself i've stumbled upon modem flashing so this may be something that i attempt but i'm currently trying to figure out how it all works. If you need any more information i'll happily get back to you as quickly as i can.
Quick things to close up to save time: It's running 4.3. It has an IMEI number matching that on the box. Everything else on the phone working 100% just not able to get mobile signal. Not currently rooted.
EFS folder corruption is the usual cause of network issues, baring hardware problems.

After looking into it the EFS folder seems more related to IMEI issues which i do not have. As for the hundreds of other posts i've looked through plenty but many of them are unresolved, the problem is unrelated to mine or i've tried the proposed solutions inside. I've been told the phone worked perfectly, he just switched it out because he had a note to use instead. So i'm not sure if it'd be a hardware issue and i'm not exactly sure of how to diagnose that either. However, if you know of a post that has a lot of proposed solutions i'd be more than happy to read through it.
Firstly, I'm not a noob.
Secondly, I've even opened the phone to see if there is anything loose.. I used to repair phones, and hardware wise everything looks fine. Plus, the issue can happen while the phone is just sitting there, it isn't caused by the phone being moved that I can tell.
So I might suddenly have a voicemail show up, because my phone didn't have signal. Or if I call out, it never gives an error of any kind, it just doesn't ring.. same idea with text, sometimes they just come in all at once.
But the whole time, it SHOWS I have signal. If I search for networks(Settings>more>networks>available networks) when I have no issues, it searches, and shows US or AT&T(which is odd since I have tmobile, but whatever).. if I do this while I AM having the issue - it doesn't search, and nothing shows. Hitting search doesn't do anything.
If I put into airplane mode and take it back out, it will show no signal until the problem goes away. Restarting the phone doesn't appear to solve the issue.
I'm at a total loss here. I've searched - a LOT. This is kind of a hard issue to search for, haven't seen anyone else describe something similar.. so I am just throwing this out here, hoping someone might have some thoughts?

did your efs changed?
cause if you have generic imei that should be the problem

I clearly said that I can receive calls and texts.. just not all the time. I had a problem with my EFS a long time ago, but was able to fix it, my IMEI is good, and I can't see any issue in my phone information(including serial, etc). As I said, this is an intermittent problem- right now I would say the issue only happens 20% of the time, maybe less.
It isn't often, but I have had multi-hour phone calls, and none have ever been disconnected by this issue, tho I feel like if I wasn't on the phone the issue would have happened at some point..
Let me point out that this has been going on over two months - in that time I have used stock roms, slim roms, every rom and android version from 4.1-4.4 and many kernels - none seemed to remotely effect the issue.
Is there a possibility of some strange modem thing? My friend has the us variant of the s3, and he has read that he can't downgrade his modem.. so I've avoided using any early modems just in case.. our phone seems to have less and less updated threads for things like modems.

Actually, you can change your modem, but if you went to the 4.3 version of touchwiz, try using other modem from another 4.3 tw, you can give a try, but dont use a 4.1 or 4.2 modem, just a 4.3 modem, (efs2)

I think that was when I had my original efs issue - I was unaware about not going down below 4.3 again- but like I said, that was fixed. Or at least I think it was.
Is there a process to going to efs1 type partition? Perhaps if I properly go back to the original type.. and then upgrade properly(all after backing up my EFS of course..)
I guess the real issue is- could this be related to my problem AT ALL? I mean I get reception most of the time(guessing80%+), and it doesn't even show a signal loss when I can't find a network operator by manually searching!
I guess another thing that has me curious - it shows US or AT&T as the network operators, even tho I am on tmobile(not even pre-paid or anything).. if I select US it works, if I select automatic, it works, if I select AT&T it says your sim card doesn't allow you to register on this network..?
I'm just at a loss, because it doesn't seem like a hardware issue.. I'm actually on the phone with tmobile at the moment trying to see if MAYBE it is something on their side, how they have me registered on the network.. something!

Bro like the said says "Once you go black, you never go back" lol jk, i read somewhere that once you go efs2 is difficult to go to efs1 you will face "UNKNOWN NETWORK", the only thing you left to do is, restore to stock tmobile, root, use triangle away, unroot, flash again stock, and go to your network operator and tell them what problem you have, i think it my be a problem with the network problem idk more, im out of ideas, you should try that. thanks for reading

So you're sure you were having an issue just like mine? I've read dozens and dozens of threads for tons of samsung devices.. I recall one of them talking about patched modems - any chance you can post the link or even upload a flashable? If this turns out to be a fix.. you will be a god among men!

Yeah more or less what you were facing. Internittent network drops.
Dropbox link for patched MG4
Let me know if it worked out.
PS: If that doesn't work, then you can also try a modem for your region. Currently using NA8 right now and no issues shifting between stock 4.3 and KK Roms

I'll definitely give it a try.. where is the source you found it from, how did you figure it out? I found this emergency zip uploaded by justarchi that looks like a patched modem.. is this it? http://forum.xda-developers.com/showpost.php?p=43946365&postcount=15
Otherwise, for curiosities sake, if you figured this out(and it does fix my issue), I am QUITE curious how you figured it out!

I found it on xda long ago. But since it took ages to find the link, I bookmarked the link so I could post without having to spend hours scouring threads for it. It was originally in the modem/baseband thread.
AFAIK, JustArchi was referring to old modems no longer working with stock 4.3 firmwares and the resulting corrupted IMEIs when you use old modems or tried to go back to 4.1.2.
This post on my thread recommended patched MK6 kernel + patched MK6 modem.
But I went with just patched MG4 and worked. The issue at that time was no network, but I've been able to resolve network drops with patched modem.
This is just my experience though.
Before you flash the modem, make a backup in PhilZ Recovery first. Backup efs and modem both.
Hi there everybody.
So a friend of mine bought a used Samsung Galaxy S3. Now he was like "doesn't work somehow" and asked me to fix it, yaaay.
The device could not connect to the selected carrier. Or better: It connected but we got a popup telling us, that the device could not get registered in the network. Seems to me as the previous owner of the phone was messing around with it, for example I found an empty cwm-directory, but didn't have root-access. Seems to me as this phone had several roms in the past and that is was flashed with a stock-rom before the sale. So I continued my search and finally found that the phone had a 0049...-IMEI --> corrupted/invalid IMEI. So I googled around, found a few fixes and stuff and after 2 hours of several flashs, roots, unroots, resets etc. I finally got the original IMEI back.
Still the phone cannot register in the network, also I have a black/yellow box all over the homescreen with some technical info - as far as I understood from google, the phone is in some kind of "factory mode", whatever that is.
My question is very simple at the moment: What to do next? Is it possible to save the device? Or do we just have an expensive mp3-player now? I found some stores online telling me to be able to fix that, but I don't really know if they are trustworthy, also it seems kinda senseless to send the device half around the globe.
I made some pictures of the current status, see http://imgur.com/a/rW70Q
Phone is set to german, but you should get the important things.
Best wishes and thank you,
Philipp
