Hey all,
I have been searching for the proper subforum to post this so I hope it's the right one.
My problem is that I have an S2 which I recently updated to 2.3.6 but since then, I started to have random reboots.
It SEEMS related to wifi because I don't have them when wifi is turned off, but I cannot determine this 100%.
Over on the GoT forum, dutch users are reporting the same issue.
Phone specs:
Productcode: GT-I9100LKAXEN
PDA: KK2 / PHONE: KI4 / CSC: KJ1
Non-rooted.
Whether I have a stock ROM or not I do not know, I'm quite sure it's not branded but Samsung doesn't seem to know either.
KIES says that I have a XEN firmware, I'm wondering if this ROM is for the Netherlands, or Europe, or worldwide(if that exists) but this is not my main concern.
Now, I've been battling with Samsung NL over this issue via Twitter, but the messages are mixed. A few days ago they announced an update, then OTA, then they went silent. Now they are saying they don't know when they will bring out an update.
All I know is that it is very frustrating to have a phone which keeps rebooting AND to have Samsung not give me clear answers.
Does anyone have a clue? Where do I begin troubleshooting this?
Before, this issue was nonexistent.

If its branded then its branded with network stuff fairly easy to spot .
Unless you flashed custom then its stock .
Presume update was via KIES or OTA ???
If you updated then first choice is backup data and factory reset .
Second is to redownload firmware .
Third is to go the self install route .

Update was via KIES, OTA updates have never been available for Dutch T-Mobile customers. AFAIK.

I'm sure the ROM is buggy, but I'll try a factory reset next week.
Is this problem only with this ROM? Nobody with a stock 2.3.6 ROM experiencing this?

My phone random reboots every now & then, it appears to be due to the SD card, Im in the process of reinstalling all SD programs to phone memory instead, it appears some SD cards dont play nice.
How do I remove old shortcuts of programs no longer on phone?
If u fix this some other way, let me no
Hi Iceman, I have the same issue, can't really say if its the wifi, sure I know its after the PDA:KK2/PHONE:KI4/CSC:KJ1(XEN) update with KIES.
Actually, the kies program s***s, I always have problems when updating firmware.
Think on flashing back to original with Odin, or do you have a great solution for this annoying matter...
Same here,
official upgrade via Kies (Dutch customer), and having daily reboots since.
It started after the 2.3.6 upgrade.
No idea why, something wrong in the ROM I guess, I did not install new programs. Clearing the cache did not help, also factory reset did not help.
Yeah ive started having reboots since getting 2.3.6
Kies at the time didnt have the update but the phone said there was one so i let it update using my wifi. Going to leave wifi off on my mobile and see how it goes. Will let ya know if its still going goood.
If anyone figures it out please post back, thanks
havent had one reboot since disabling wifi.
Hi,
I've updated the phone to the newer firmware from KIES, and the phone was connected to the WIFI network but signal connection keeps switching on and off, is there anyway to fix this issue so I can have a stable connection?
Have test with my iPhone and Ipad, both connectect to the same WIFI and only my samsung S3 having this problem.
PS: WIFI power saver mode is already <<off >>, keep Wifi on during Sleep mode is set to <<always>>, Network notification is <<un-tick>>
This is my current ROM (Rooted)
AP: I9300BUBLG3
CP: I9300BULG2
CSC: I9300VFGBLG3
settting > wireless & network > more > mobile network > automatic connections > sprint connection optimizer.. unchecked?
This is the international version is Samsung S3, I can't find such settings.

I had the same issue when I reverted to stock. I thought it was this and that but really, all I did was
Backed up everything
Well mine was rooted and stuff so I triangled away the flash counter, probally dont need that if your on stock anyways
I wiped everything from the phones settings, back and restore, reset
I then booted up in recovery, doesnt matter if you are cwm or stock recovery, wipe again plus cache
Now I loaded up Odin and flash the original stock rom for my phone, I waited till it was complete, I then updated it through settings till I got to the latest update and then started reinstalling my apps from google play store or whenever else I had apps. So far all is well and no wifi issues.
Other advise would be instead of all the above, wait for another update or flash a new modem. That also worked for me when I was running another countries stock rom, Bad wifi, so I flashed my countries modem and it was fine! so good luck!
go to dialler
*#0011# will take you into Service Mode
click on menu
click on wifi
you will see a button that says "on" click on it
it will say off this stops the wifif connect/dis-connect problem.
If you shut down your phone you have to reset it to off.

I've got the exact same problem. Do you have a BT Home Hub 3 by any chance?
I've just rooted mine so am going to try and flash a new modem and see if this fixes the issue

Sorry I don't have BT Home HUB 3, my connection is very simple, just connecting the S3 to a DrayTek Vigor2710Vn Router via Wifi. Please let me know the result after you flash with a new modem. If is working, please provide the link and file name where you got your file so I can flash it too.
Thanks!!!!
***By the way, what ROM version are you using at the moment? Please provide your AP, CP and CSC details if is different to my S3. ***
Repeat Modem has nothing to do with WiFi.

I had the exact same issue, but ONLY after rooting the device (which I did just a day or two after I got it). I tried every possible fix, flashed new roms 3 or 4 times, wiped data and everything else in recovery, but no luck.
However, my final solution was to simply follow a guide to unroot the device, which I did today - and it did indeed work, I guess this issue is mainly happening to rooted phones, for unknown reason. Until I know this is fixed with an update (maybe in 4.1 JB), I won't be rooting this device again.
Link to guide on how to unroot
Are there actually people who can't fix it like me?
Also done everything I possible could but never got wifi working again.
Returned it to Samsung. I unrooted it and flashed the firmware again with KIES.
The day after there was also an official update for the BENELUX I guess. Also updated this with KIES.
So is it still possible they see that the modem was changed?

Yeah as the guy above me said, you always have to reset the flash counter before unrooting (as this requires superuser access).
If you don't do this, it's easy to see the phone has been modified in either download mode or by checking status in settings.
After successfully unrooting you'll also have to re-enter CWM recovery and wipe data+cache.
After doing this you'll see the device being "normal" and it should show "stock" in download mode.

Forgot to mention it but I did this yes.
I also think KIES would not update when this is not a zero.
I have a i605 with Verizon. It's rooted and I've been running Jellybeans 22 (4.1) since August. Saturday I decided to install the new 4.4 with CyanogenMod 11 which just came out. I goofed and installed the 7100 copy (I think it was 7100, started with a 7). I got a no service message which makes sense. Ok Mark, what's next dumbass? lol so I got the right version and installed it, and still didn't get service. So then I rolled it back to the image I made before I started this whole thing and still no service? I read other postings and checked for phone number and IMEI which are populated. ERI version is 5. I also keep getting a message asking me to go to a GLOBAL setting which doesn't help either. I tried pulling the SIMS card and rebooting. The instructions said to put the card back in while rebooted but the power supply blocks that. Soo.... do I try to get my stock installed or is there other things I can try.. There's this cute chick who likes me and if I can't text her I might never get laid!!!! (I wish )
I also had the same problem of baseband and imei showing unknown but I was able to fix it.
thanks,

Should I unroot
Should I unroot the phone and go back to stock to see if it corrects the issue? Will I need to accept an OTA?
Use cwm.

I would do what hopesrequiem suggested. If you are using TWRP to flash CM11 you wont have data. You have to use CWM 6.0.4.3 for some odd reason.

what Went South was I couldn't make phone calls or text. Even after restoring 4.1 Rom. I didn't have issue with data. But to answer my own question. . I fixed my issue by restoring my stock Image and then used setup / backup / factory reset. That did it. When I restored 4.1 it was working again. Thanks for the info on cwm version.
Well im glad all is well now!

Hello all,
My partner bought a Galaxy S3 (GT-i1900) International (I live in the UK) off a friend .
We noticed that the network connection periodically failed. I noticed that the software was some of the earliest on this phone, and so i thought I'd better update it, as it was suggested that sometimes if the phone is running some of it's earliest software it can cause problems with the network connection, and as it works 95% of the time, surely it can't be the antenna? I went to software update and tried to update it there, it's then I realised the phone had been rooted, and even Kies would not update it. I came to the conclusion that perhaps my friend had tried to mess with the phone some how, and may have caused this network problem, or perhaps was trying to cure it? Who knows
I decided to flash the latest stock rom (i9300XXUGMK6_I9300OXAGMK6_I9300XXUGMK6_HOME.tar.md5) I found on Sammobile. Everything went well, the phone booted up perfectly, the only minor worry being that the first screen was in Polish, quickly remedied by changing the language to English UK. All seemed fine, until we tried to make a call. it was then we realised that there was no network connection whatsoever. I tried other sim cards with other networks - still no connection. It only shows the signal bars.
I read the forums for a couple of days and tried:
Going in Network Settings and searching for my network, 3, which it found amongst all others. it said 'Registered on Network' but then immediately flashed up '3 network not connected' or similar. fail.
Installing CWM recovery, then flashing the 2 modem zips (DDEMG2 & XXDME4) all went fine, but the phone still says 'disconnected' under Device settings Mobile network state
Using the Ariza patch. I tried this, but on the last step where it says 'just click patch' mine gets stuck on a downloading state, possibly as I'm using a stock rom I read some kernel has to be changed first? - Beyond me.
It was then I decided to scrutinize every difference between my working S3, exactly same phone on same network, and my partners.
The IMEI number was correct, something I see people have problems with. The signal strength reading are the same, suggesting the antenna at least is fine.
The serial number - Now this is the ONLY thing I can see that seems to have been changed, from the correct format, to one starting with 4df1 ...... Is this the problem, that has made the phone not register with network? In the UK phones are not locked into a specific phone number /contract and so I don't see how the network would decline a differing serial number?
Anyway that's where I'm at a phone that has no network connection, with a differing serial number.
Any help would be GREATLY appreciated.

Screenshots of the device status in case that helps . SCREENSHOTS REMOVED DUE TO PRIVATE INFO
I've noticed after Googling the baseband version, it says 'New modem DDEMG2 (16/07/13) India,Sri Lanka,Bangladesh'
I live in the UK and have a network free unlocked unbranded International S3!
Surely the steps I followed to flash the modems as stated above are incorrect?!
Do I need to flash the UK one?
Anyone know which one for 4.3?
How do I do it and where would I find it?
Any help greatly appreciated!

Hi couple of things first you have posted screen shots with your mobile no and Imei no on I would delete them
I am pretty sure flashing another rom won't fix your issue you can easily use roms from a different region and still have full network connection but you can give it a try as suggested above.
First thing first because you have upgraded your phone your efs as changed from efs v1 to efs v2 (which you probably already know) flashing the (DDEMG2 & XXDME4) modems would not work because you need a modem later than mg4 for 4.3 roms.
What you need to try is flash a patched mk6 modem and kernel from here >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << flash then reboot if you get stuck in a bootloop factory reset and wipe cache in recovery.You could also try this >> http://forum.xda-developers.com/gal...ii-network-problem-update-sn-t1918601/page199 << look at post 1984 this is basically the same thing with a rom included and as had some success.
If the patched modems do not work and you don't have a efs backup then I would suggest you need to send for repair.

Thanks. I have absolutely no idea what EFS is or how to back up. I would never have usually played with a phone like this it's just my partner was getting fed up of the connection disapearing every now and again, forcing her to reset. I have about 12 hours worth of knowledge on root access, flashing and modifying phones. I am worried I'm going to completely brick the phone. Is there anyway I can make a back of the phone as it is so that if I mess things up I can some how reset it, as at the moment I have Nothing as such. I am going to read up on EFS, I suspect due to the fact the phone was already rooted when I bought it, yet still stuck on the original software and and not updated in anyway, with a pre-exsisting network connection issue, that the phone was already un fixable. I hope not.
I will try all the steps suggested and post results.
Thanks a lot people
ps i hardly have any experience of using forums so sorry if i'm making a mess of this

Don't worry just take your time and read all the guides if you install a custom recovery you can do a nandroid backup which is basically a full backup of everything on your phone and will restore your phone to how it was before (if you do it right) I recommend using PhilZ recovery and flash it with Odin.

Yep that will do fine although you are backing up a partially corrupt efs that's the reason you are not getting a signal because the efs v2 can't read the modern correctly that's why you may need a patched modem & kernel to help read it.But back it up anyway in case the efs gets any worse and gets totally corrupt.

That was my thinking, the IMEI isn't corrupt yet so I thought best to back up what I have. Ive also backed up using CWM.
Im now trying to flash the proper version of 4.3 for my unlocked uK S3, so im at least using the correct os.
Im flashin zip from cwm, but when i select it on my sd card, it says the following:
Finding update package...
Opening update package...
Installing update...
Installation aborted.
Any ideas why it won't install? Iv'e been Googling it
for 2 hours.
cheers
update - I spent ten hours downloading the proper rom 4.3 btu uk unlocked one, finally flashed it using mobile odin.....
started in Polish again - with no network. I think that this is standard.
Next, I am going to try to flash the patched modem.
tallman43 - do you think my strange serial number needs to be corrected? Is this possible or necessary?
Many thanks - one very tired migraine creating finger-nail biter.
Update:
I finally got the phone to work by following the instructions on the page below;
http://forum.xda-developers.com/galaxy-s3/help/guide-fixing-gt-i9300-network-4-3-stock-t2609635
The patched kernel didn't work on it's own, but the kernel I installed from this thread, along with the other two files, seemed to work, and though the phone is now registered using a much better Android 4.3, it still disconnects every now and again forcing a restart. I really wish I could work out why it does this, I'm starting to believe it may be a hardware issue now.
Is there a program that I could use to test the part of the phone that malfunctions and loses signal completely, to try and work out what is happening when the phone suddenly loses all signal and shows only a circle with a line on it (no sign)
Many thanks to all the people who helped me with this I really appreciate it.
I want to close this thread now as what I require now is off topic from the original post so many thanks for your help people.
Hy everybody. I'm here to took with you about a common problem on samsung s3. One week ago i notice that i can't receive calls, messages etc and i found the "not registered on network" problem. What actually i want to say, is the fact that it appear suddenly, my phone always have 4.3, i didn't upgrade nothing....the problem persist, i changed sim, modem.bin, flash 4.1, modified network connections from setting....nothing work!!! I always have signal but that's all....what can i do more? (and my imei has changed to this: 00499*******

thx man, i hope someone knows how can i solve the problem.
What had you done before you got to this issue of no cellular signal?
Did you flash a custom ROM etc..? Which version were you on before? 4.3?
What did you do after you found out about this issue? Did you by any chance flash an older version?
Because that tends to do that, atleast that's what happened to me.
I had a wrong/fake IMEI ("0049..."), which caused that I had no cell reception and couldn't use the phone to call or send/receive sms etc...
I googled a lot and I tried some of the TUT on the web, but nothing helped. Until I found a thread on the xda that said one could try to flash a newer stock ROM (don't know the exact thread).
So I went ahead and checked the version I was on...luckily it was 4.0.4
I then downloaded a newer stock ROM 4.3 for my region and flashed that using ODIN...once it passed I went to recovery: wiped cache and factory reset.
and voila...when I checked the IMEI code again, it was back to the original one.
If that doesn't help check the following thread on xda: here
I suspect he allowed the battery to run out, which corrupted the efs partition, as he says his phone was on 4.3 and didn't change anything until after the problem happened.
Flashing latest stock firmware is the first step, as suggested above, but I think the OP may have to pay for a repair. Make sure it works on 4.3 before you accept the bill.
I forgot to say, my battery got bigger before that happened, i can't fit it in my phone, is double than a normal one, i buy other battery, have this something to deal with the problem?

I googled a lot and I tried some of the TUT on the web, but nothing helped. Until I found a thread on the xda that said one could try to flash a newer stock ROM (don't know the exact thread).
So I went ahead and checked the version I was on...luckily it was 4.0.4
I then downloaded a newer stock ROM 4.3 for my region and flashed that using ODIN...once it passed I went to recovery: wiped cache and factory reset.
and voila...when I checked the IMEI code again, it was back to the original one.
If that doesn't help check the following thread on xda: here

I was on 4.3 version, i didn't do nothing, i even not installed the root/cwm....the problem appeared from nothing...right before i change my battery. I tried with my region stock rom (4.1.2;romania) and with 4.3 stock ROM but didn't work.
Today i let the phone on a service....i told her what is the problem and i hope there's nothing to do with motherboard. Anyway, please let me know if there's something else to do while i wait 3-4 days for the answer

That's not good...bulging/expanding battery is a very bad thing and should be replaced asap.
Why it happens, is another thing...could be due to various reason such as thermal runaway or even acid leakage.
Fix that first before you move to any flashing and/or other stuff...

I already replaced it.
Fixed
Hi everybody, i finally sent the phone to service and they fixed it for 17€; everything ok, no problem occurred...i flashed stock 4.3 ROM, then CWM and SU, but....then....after one day of use, i forgot to shut down the phone and, again, removed the battery with the screen on....i connected quickly the battery and the phone started without press any button.....and then, surprise!!! Me trying to make a phone call: "Not registered to network"...fu**...but IMEI was still alright(w t f?). Third day i sent again the phone to the service and they told me that i am playing whit the soft (what man? just because i flashed CWM and SU? damn), i told them again what i do with the battery and they said is not true (now what i am supposed to do? they don't trust me) but fixed it again free..for first and last time. Now here is the question: what i need to back up in case that will happen again? It can't be fixed with a backup of IMEI/Modem file...
