[Q] Not registered on network - Galaxy S III Q&A, Help & Troubleshooting

Hi everyone,
I have galaxy s3 i9300, I flashed cyanogenmod couple of month ago and had troubles with the battary and the gps signal so i wanted to go back to the stock rom.
First, i restored a backup from the original stock with CWM but than decided to install a new one so i downloaded rom from sammobile and installed it with odin. Apparently i made a huge mistake cause since than i cant register to a network.
My IMEI is FINE - the same as written under the battary.
Read alot of threads about this issue, most of them related to a problem with the imei...
Tried this:
1. flash another stock rom
2. flash another rom (PA)
3. install other modems
4. re-partition
Non of them works for me...
I would have tried restore the CWM again to original stock but now having trouble with the CWM reading my external SD.
Thanks!

Your IMEI can still appear normal and be corrupt did you try the patched modem and kernel method.

If you are meaning to install the XXDME4 and than DDEMG2 Zips so yes.
If not - can you send me a related thread or explain more about it?

Are they the patched modems and kernels they have to be patched to work not just flashing the newer modems although that does work for some.
Try this >> http://forum.xda-developers.com/gal...ii-network-problem-update-sn-t1918601/page199 << look at post 1984 by west421 this as helped a few people also here are some more patched modems and kernels >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << flash the modem and kernel not just the modem.

Glad it worked
Not I00% sure I think it's more the modem and kernel that you need I just know that particular combination as worked for some people.You could try another rom then flash patched modem and kernel after just make sure the rom is compatible with the kernel.
Also you will always need to use the patched modem and kernel files or you will lose signal again

[ROM][4.0.4][GT-S7562] Baseband Flashing Issue

Hi
I have installed PMP Ultra ROM on my GT-S7592 following all xda appropriate "how to". When it was done, everything was ok but impossible to call or receive calls, I had Network issues (network not connecting, stopping when trying to call for no reason).
Reading the forums, people look to be saying that it was coming from not having the right Baseband. I checked and yes the baseband didn't get updated when I flashed the advised stock rom in ODIN. So I tried it several time, even with different roms (S7562DDBMD1 and S7562XXBMD6) , but still my original baseband S7562ZSMK1 remains.
My results so far: Baseband didn't change accordingly when flashing with ODIN but Build Number did change to IMM76I.S7562DDBMD1 and IMM76I.S7562XXBMD6 and stock ROM got installed.
1- Are my issues really coming from this modem version?
2- If yes, how do I get the Baseband properly changed?
Kind Regards
Dam
solution??

Problem is: how to do it? I'm on stock ROM and no matter what stock ROM I flash, the baseband will always be the same, like if it's locked or something.

All zips I could find where entire ROMs which are suposed to change the baseband, right? Problem is: when I flash them, the build number does change, meaning that something worked, but the baseband does not.
Could you link me to one of those zips? Preferably the one you have used (if you used any) so I can make sure the problem is not me doing something wrong.

I know, it should work. I'm receiving an error message every time I try to flash the fat.bin file with Odin, be it when flashing a whole ROM or only the fat.bin file: "Secure Check Fail: ID 0xc". I researched a lot, but couldn't find an applicable solution. I couldn't even find what this error message means.
Friends, any help on this one? A friend of mine has entrusted his S-Duos to me; the baseband of the same would not budge, whatever I flash. I tried flashing fat.bin file from various stock roms, every time the above mentioned error occurs in Odin.
Edit: The current baseband version is S7562ZSLI3 and the rom I flashed is XXBMJ1.
CWM Recovery
First I got to ask, Do you have CWM Recovery installed? if yes, Do a factory reset with it then. Then go to Advance options Format System partition, Data partition, Cache Partition.
Then reboot the phone normally to be sure that has formated. If it boots up to android then its not formated, but if it gets stuck and Samsung logo for more that 5min. Then its bricked and you are good to go.
No remove the battery and boot to recovery (Volume up + Volume Down + Home + Power buttons) Now install ROM from SD.
That should solve the issue. I have a S7562CHM version and now its S7562XXBMJ1.
Hit thanks if it works.

[Q] GT-I9300 not registered on network

Hey, guys!
This is my first post in this forum.
My situation is the following: a friend of mine came to me because her SIII GT-I9300 was stuck in the SAMSUNG screen. After a little research on the internet, I did a wipe data, which did not work. Then I researched a bit more and flashed Android 4.3 using Odin. Android was running OK, but I got "not registered on network".
My question is: in order to fix this problem, should I worry about the IMEI? (when I did the wipe data i didn't do any backup...:silly.
Any help is welcome. Please have in my mind that I'm a noob...

Yes root it then install cwm recovery then download zip file and put it onto your internal sdcard
Then reboot in CWM and use "install from zip".
Well, guys...
I did what you said... didn't succeed. I installed those patches, but it still says "not registered on network".
I wonder if it is an IMEI / EFS folder issue... As I mentioned on the initial post, I don't have a backup EFS folder.
Should I try to flash the stock ROM (I mean, the factory native ROM) so as to try to recover the IMEI?
If so, I don't know what was the original firmware because I got this mobile from a friend.
Any ideas on how to figure it out?
Thanks in advance.

I'm really thankful for the tips... but is there any tutorial on how to flash MG4 modem?
I've had a quick look on the net, but I couldn't find any 'step-by-step'...
I mean, do I have to save those 2 files (modem MG4 + kernel) in the SD card and flash using CWM?
Where can I download it?
Thank you all.

https://drive.google.com/folderview...usp=sha+ring&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8
these are released after 4.3 upgrade with the issue not registered in network
Flash
I would go back to an older version of standard rom. See if that restores imei efs back to version 1. Sammy mobile unbranded uk is version 2 so use an older version than that. I have gone back to this from version 4.3 stock. If phone boot loops after flashing do full factory reset. Then check imei. If still not ok. Install kies and it will upgrade to 4.3 and imei will be back.

Koj,
Could you please post the link for the older version of standard rom? After flashing it, how can I check the IMEI EFS version? I just want to be sure I'm strictly following your tips.
Just to remind you, I got this S3 from a friend who had bought it in USA, and now I'm trying to use it in Brazil.
Thanks in advance. Greetings from Brazil!!
http://www.sammobile.com/firmwares/1/?model=GT-I9300&pcode=ZTO These are a list of Brazilian roms choose the september 4.12 version. You will need to register before you can download. To check imei go to about device then status or from phone keypad enter *#06#

[Help]I9300 no network

Hello,
story is as follow:
Nandroid my original rom, flashed revolution hd 52 rom, and troubles arrived.
Problem is that my NANDROID stupidly got deleted when I cleaned to install new roms.
RESULT:
No network/emergency calls only...
IMEI and product number wrecked, everything was destroyed.
After numerous tries of flashing via ODIN, stock firemware, I managed to flash:
I9300XXUGMK7_I9300OJKGNB1_I9300JKUGNB2_HOME.tar
Which restored my IMEI and Product number, but no success in the network side.
Tried also flashing every single modem i've found and still no success
Tried Ariza also.
I had alot of hope at the beginning when I read that the "state" of the the phone can be restored via kies, but no matter what I did> GT-I9300 "doesnt support initializing"/
I passed on most of the topics about this problem and I don't know what to do next.
++ I have another galaxy s3 phone, using the 2nd phone efs folder can somehow help ?
Please,
help me get this phone up and running
Thank you very much !

First,
Thanks for your answer.
Second,
I tried and flashed his emergency modem, still same problem, IMEI & Product number are fine, still no network.
I've already looked at the second link you gave and didn't get any solution rather than sending for repair.
Thanks again.
Ok no problem I'm not at my computer now but there is also a patched Rom modem and baseband on the forum somewhere that as had success restoring signal can't post links cause not at pc..

LIKE A CHARM !
Thank you so much !
I have three more questions:
1. The fact that flashing this specific rom. kernel and modem means I can't change to any other rom ?
2. Backing my EFS folder can help in case of switching rom ?
I'm asking if my EFS folder is now fixed and backing it up will be same as if I backed it before touching my phone?
3. The 3g connecting is rather slow,the blame goes on my Carrier or that there is a slight chance that the modem I flashed / kernel makes the
connection slower ?
THANK YOU A MILLION TIMES FRIEND !

Glad it worked:good:
(1) I think you can change to any 4.3 rom as long as you flash the patched kernel and modem (not 100% sure)
(2) Backing up efs is never a bad thing (I don't think it is back to how it was or you would not need to use the patched modems kernels)
(3) Here is a link to some more patched kernels and modems (you could try a different modem) https://drive.google.com/folderview...&usp=sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8
I don't think the efs is fixed completely only a original copy took before your problems started would fix that (might be wrong on that)
If you have got the courage you could always try other roms etc and see if it works,at least you know how to return it to working order.

not registered on network

hey there everybody
i have a serious issue and i think i could use your help
well previously i was on stock rom 4.2.2 on my I9300, then i flashing 4.3 manually using odin and downloaded the rom from sammobile anyhow since i flashed that firmware i can no longer access anything on my sim card, meaning i cant call or receive any call from anyone, it keeps saying no registered on network, then i thought it could be the rom or something, i tried pa rom and cm official latest builds but in vain, the same issue, i tried changing the sim card but the same, issue not resolved....how can i solve this prob, i wish it is just a software issue not a hardware
i also tried following this link, i thought it would help somehow, but in vain as well, now i have no idea what to do to solve this issue, tried reflashing another stock rom which is probably more appropriate than the old one, but also it didnt work, so now i have no idea what to do, i just need urgent help please, thanks a lot in advance

pardon me for im new to this patch and modem, so i have no idea according to what i have to choose
btw dude, i just noticed that there is another stock 4.3 rom for my country, would flashing that stock firmware be of any good and solve the issue?
NOT WORKING, I TRIED
okay buddy i got it to work, flashed patched kernel and patched modem using twrp in one go and it did work, couldn't wait for your reply though, so now it is working peacefully and i can access my sim, calling sending sms etc, but i wanna know how to backup efs, or actually is it necessary to back it up, can't i have the patched modem and kernel files for solving this issue whenever it arises?

Hi sorry I have been away from computer i'm glad to see you got it working You will always need to use a patched modem and kernel the only way to return to normal would have been to backup your efs before it got changed. As for backing up your efs you can back it up with PhilZ recovery I'm not sure about twrp iv'e not used it for a while. There are are a few apps/programs that can back it up also just do a search on xda. But remember you will always need to use the patched modem/kernel if you change roms.

Because when you flashed from 4.2 to 4.3 your efs got changed from efs v1 to efs v2 and in the process it got slightly corrupt so it was unable to read your modem ( This happens some times and you where unlucky) .This is a lesson for all people to make sure they backup the efs before flashing roms ( Especially the very first rom that they flash) it is the very first thing you should ever do.
IMEI changed after flashing to 4.3 jellybean GT-I9300

The one that says kernel is kernel patch and the one that says modem is the modem patch lol Try the mk6 modem and the mk6 kernel patch flash them in custom recovery with 4.3 rom. If you get bootloop reboot into recovery and factory reset. Please note this is not guaranteed to fix all imei issues but does help in some cases.

Is there a possibility that there's a way that I could just wipe my entire phone clean of all partition and data and start a fresh firmware update?, if so how can I do that, as I have a corrupted file then I think if it can be done it might just work a fresh firmware flash on a clean system??

Read here >> http://forum.xda-developers.com/galaxy-s3/general/ref-imei-efs-stuff-i9300-including-t2393289 << Also you can always pay for a service repair if the patched modems do not work.
important NB: TWRP recovery do support EFS backup with encryption, so i guess it is great to have a sensitive data such as EFS to be backed up with encrypted password, so i do recommend using it as a backup
Hello All, I'm pretty new to all this and am feeling out of my depth, however getting desperate and don't know where to turn next.
I am in Australia and purchased a brand new GT-I9300 from eBay around 3 weeks ago which was shipped from Shanghai, China.
It turned up running 4.1.2 and worked just fine. I tried using the software update feature on the phone to see if 4.3 was available, however, I got the error message to say that because the phone had been modified, software upgrades were unavailable. I mentioned this on a local forum here, and someone kind offered to help me upgrade to 4.3 using Odin.
Turns out the phone was shipped to me rooted and had SuperSU installed. Had to install and run Triangle Away to reset binary counter first. Then installed Odin and followed the links to the firmware and this is where it started going wrong. Fist attempt resulted in a boot loop and could not enter recovery mode to factory reset, however could access download mode, so flashed with 4.3 recovery firmware which got the phone to boot up. Then flashed 4.3 stock firmware again, which was successful this time. However, when trying to make calls or send text messages, the error message on the screen is "Not registered on network". Have tried going back to 4.1.2 and upgrading using Kies, but same result. Then tried the patch from here http://forum.xda-developers.com/showthread.php?t=2745274 and still no luck.
I then sent the phone half way across Australia to Official Samsung Specialist Repair Centre, however, they called me yesterday, to say that because it was an international model, they can't/won't help as they don't have access to international firmware.
If anyone here can help me to get this phone working again, I would be very grateful. Thanks.

Thank You. The phone was posted back to me yesterday, but I won't receive it back until the end of the week. Once I get it back, I'll try this out.
I'm very sorry to have to ask this, but could you give me a bit of a step by step by what you mean?
Thank You again.

Many thanks tallman43, I managed to get someone to give me a hand with giving your idea a try. Just wanted to let you know that it worked, and my GT-I9300 is now back up and connecting to the network and running with 4.3. Thanks again, and much appreciated.

[Odin][Odin Flashable - Bootloader/Modem][G900TUVS1FOL1]Updated 2/1/16

Made this for myself, and noticed other people wanting it. If you are in anyway unsure of what your doing, please don't flash Odin packages. I'm not on here all that often to answer questions, so please refer to aaricchavez's thread as I'm sure the same questions will be asked.
I was able to flash by pulling the battery, then vol-dwn + home + pwr. Choose vol-up for downloader and flash. Worked on the second try. See screenshots bellow.
What you do to your phones on you, consider this: Warning flashing Bootloader/Modem/ FULL FIRMWARE LOLLIPOP
Updates seem to work best after a shutdown and battery pull. If camera stops working, clear your caches and reboot.
Flashable in Odin:
Bootloader/BL:
FOL1 Bootloader
FOL1 Bootloader
Phone/CP:
FOL1 Modem
FOL1 Modem
TWRP Recovery:
Recovery
My Customized Recovery:
2.8.7.0 Recovery
I have tried numerous times to install bootloader but it stays on dob1. I got the modem just fine. Don't understand why

I've tried updating my bootloader& modem as well as the firmware in Odin 3.09 & 3.10 & all it keeps doing is failing can someone PLZ help
The only way I've been able to flash the last few modems and bootloaders is by pulling the battery, and even then It may take a few times. DOB1 took me 4 or 5 times.
And if your wondering, the modems a huge improvement. At least for me anyways. I'm up in the hills of the SF east bay and got very spotty LTE before, no longer an issue.
Could I use flashfire to flash the boot and modem?
Edit, I know it's possible to flash full firmwares but not sure about boot and modem

Can I flash just the modem if I'm already rooted using a CM12 ROM (Temasek unofficial)?
Does flashing a full stock ROM immediately update the bootloader and modem?

Yup. On rare occasion partitions respond in strange ways to odin flashing, ie. partitions other than what you're flashing become unwriteable. But for the most part that's a rarity.

Depends on your existing version, and the version your upgrading to, but with rare exception yes.
Is this the newest BL and modem for our phones?

As of 10/10/15 FOG6 is, I just uploaded.
thanks for this. just realized today there was an update.. only a one letter difference, took a while to realize it!
can someone upload the new one?
Just wanted to add this. Was having a hard time flashing BL and CP
1. removed the sd card (tmobile thing I read somewhere)
2. took off the md5 off the file name so it was just a .tar file
3. put both files in to oden 3.11 and on the first flash had auto reboot NOT checked, then pulled the USB cable and pulled Battery.
4. then booted to download mode with cable in and and battery in and reflashed with auto reboot checked.
I installed omega rom v20 and I had a bootloop because I didnt have a 6.x.x bootloader and modem.
I came from 4.x.x and I almost just installed a stock 6.x.x to get the updated BL and CP, then root that.
I have had good luck with omega, but I use TB to clean out all the Samsung stuff. I purchased the App for $7, worth every penny.
