Strange... If you really think it's not working, you could reflash the radio via ODIN, by taring the MODEM image, and flashing it in a tar as MODEM.
But I doubt you need to. You tried the SIM in another phone, in case there's network downtime?

SIM is working, tested.
made now a factory reset, now bootloop
may an idea where to get an radio to flash via odin ? im on villain 1.1 btw
or is the radio included in your ROM ?

Since i updated Radio i lost 3g connection

I just updated my HTC Hero radio to the latest version and since then i can't connect to 3g.When i click on Mobile Network tick it just freezes but not connecting.Any ideas what can be wrong?
Note that i tried nandroid restore and its not working.I mean its not restoring old radio.Is there a way to go back to my default radio or just any hint on what might be the problem?
On default ROM i get an error message that its like that: Use phone for data connection when Wi-Fi is unavailable.
Just flash an older radio...
Have you tried re-flashing the custom rom? May fix it.

WIFI keeps getting on and off

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.

This was the latest stock rom from KIES update (also rooted). But thanks for the reply, I'll try to flash different ROM and see what will happen.

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.

I also think KIES would not update when this is not a zero.

[Q] Intermittent network problem GT-i9300

Hi,
Firstly thanks for time and sorry if this is a noob question but I only have a fairly small amount of experience regarding custom roms.
Here goes...
I have changed the rom on my phone about 5 times over the last couple of years and never had a problem. I have the latest version of teamwin and I'm currently running Android Revolution HD 50.0 by mike1986. This rom works great as have all the other I have used in the past ie Cyanogenmod, Omega etc but the problem I am having is over the last 4 months I am completely losing network and even if I try to search for a mobile operator my phone can't find any unless I run a full power cycle.
I have been reading as much online mainly xda-developers to find a solution to this problem but I'm afraid I'm now just running into a brick wall. I understand this could just be a hardware fault but I have read somewhere that I may have the wrong modem installed for my phone.
How likely is this? Can having the wrong modem cause intermittent problems? Also if this is the case where the I find a tutorial on correcting this issue. Plus which modem should I be using in the UK?
Again thanks for you time and any help would be much appreciated.
Mike
Do a full wipe and flash the latest stock firmware for your country, then factory reset.
Test fully before you install or restore anything. If it is still the same then probably hardware.

ok, Will do. I am just waiting for the UK stock firmware to download. I left it downloading while I was out this afternoon and for some reason it failed and now is asking me to wait an hour before retrying
I'll let you know if this solves my problem.
Thanks
ok..
I managed to get hold of the stock firmware from another site. I first installed a version of ICS so I could run triangle away properly after rooting with CF auto root as without doing this I couldn't reset my binary counter even after flashing stock recovery. Then I installed the latest version of JB and ran the official Samsung update to get my phone up to the very latest Official software with device status official.
So now my phone is completely back to if it just came out of the box. I finished late last night and installed nothing but WhatsApp. Then at about 3pm today again I completely lost network and couldn't restore in without a full power cycle. Even searching for Network operators in settings couldn't restore the connection. I can't think of anything else to try.
Any ideas what to try next please?
P.S. The firmware I installed is as far as I can tell for my location. I'm in the U.K. and I'm using the stock BTU version on baseband version I9300XXUGMK6
the same i9300 problem

This is exactly the issue I have now - I can get some signal, but can't get anything in terms of using 3G/Mobile data :/

[Q] No network after flashing stock rom, Android genius required Please!

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.

I have cwm recovery will this suffice?
I'm using Samsungtool as we speak to back up the EFS folder.

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.

IS it okay to flash T- Mobile on an international Gear S - SM-R750T

Can someone point me in the right way. Looking for US rom and could you explain the steps to do this. Can you help with this @cipherswitch
my model is SM-R750SZKASKC from Korea I want to use this with a US rom is that possible?
Thanks
V
Yes you can try but it will fail
I have the same exact watch and have been looking into this for the past day. So far I tried flashing T-mobiles firmware for the Gear S. Which you need to use Odin installer for but it failed. Then I downloaded and installed the origanal firmware as the factory reset was not working.
I then found a cyanogenmod ROM which I also used Odin to install and that one worked. Only when I had bought my watch the IMEI was all 0's. So I reinstalled it in the following order.
installing TWRP performing a Advanced wipe/ wipe all data
Then reinstalling Cyanogenmod and inserting my sim card.
Rebooting to TWRP to install the Gapps zip.
Then magically the watch booted with a imei number odly enough.
But it still wont connect to my cellular network.
So I am trouble shooting this now if anyone has any insight that would be great.
Heres the form to show you how to install the custom ROM
https://www.google.com/amp/s/forum....lopment/dev-gear-s-android-port-t3177740/amp/
Heres info on SK telecomm
https://en.m.wikipedia.org/wiki/SK_Telecom
Heres the stock firmware link wich I have not tested but I dont use sammobile anymore so if you want to check there sight good luck.
