It all started after flashing this rom: http://xdaforums.com/showthread.php?t=2333102

I flashed the stock leaked Sammy 4.2.2 ROM then flashed that ROM and as soon as I booted up, I noticed the emergency calls only.

I thought maybe my sim card was loose and it wasn't until I searched the forum and came upon this thread that I noticed what was wrong :crying:

Where I am located I know it would cost me an arm and leg to get this repaired as nowhere here can do it, which means I would have to ship it overseas :(

When you say "Put in place using root permissions", where is it that I need to put it. Sorry this is all new to me as tis is the first time this has ever happened

Get your efs backup tar.gz , unpack it , it will have efs folder. Now use Root explorer go to phone's efs folder , multiselect all contents in efs folder and delete it. (Don't try to delete whole efs folder coz it won't allow deletion) then copy the backed up contents from efs folder to your phone's efs folder , reboot. Done.

[Galaxy S III General] araujo3rd:
Please can somebody help me!!! I installed a custom rom from stock and ended up having problems with IMEI 4999. After days of searching it seems the only way to get imei back is with z3x box. I found a guy that remotely does this with his z3x. He repaired the efs but IMEI was still the same. I installed the latest OMEGA rom and the imei went back to the original correct imei but there was no network when trying to make calls. I loaded the stock rom again and IMEI reset to 4999 again. I then installed MG4 baseband in recovery and it restored my phones IMEI back to original correct IMEI with the stock 4.1.2 rom. However I still get "Not registered on network" error when trying to make calls. I have tried installing modems etc but nothing seems to work :(.

Any help will be very much appreciated

[Galaxy S III General] raphaelsea:
Ty bro, but i solved my problem. Here in Brazil i found a guy who work with phone repair, so he rewrite my IMEI, with a program not box only with an software for about 27EU/40USD/90REAIS. So now i am very happy, i send it for samsung oficia repair just tell me" We cant solve this problem, only thing you can do is change the MOBO, 400USD/900REAIS. so unfair because here you purchase a new phone for about 500USD/1000REAIS. So now i solved, ty guys for trying to help me thanks a lot.

Sorry for my bad english, take care and good lucky ^^.
[Galaxy S III General] maxniper:
I'm glad that you solved your problem.

My problem was that the first time MG4 was released i upgrade and then i do the stupid thing, i downgraded directly without EFS backup and returned to repair, now i want to upgrade to 4.3 but i can't use new modems other way i lose my imei it changes to 499 one.

i tried almost everything and nothing, i'm now trying to see if for luck i can upgrade my EFS_V1 to V2 but till now no chance.

Hello guys. I have a question, I tried a lot of different methods to backup the efs folder: used kTool tryed Philz recovery and many more. But I'm not sure if they really made a working backup.

First the ktool when I pressed backup and it finished it sad it was successful but when it ask to check if it's ok at the and it sad that "nv_data.bin NOT FOUND in backup !!!"

Second Philz recovery sad the same successful backup but when I tried to check the files on my pc the .img is a broken file, can't open it withe winrar.

The same is happening with every backuper. When I try to opened them they are all broken.

So my question is that should thees be broken or what ?

The IMEI isn't messed up, I only have problem with the backing up process.

Hello,

I searched and read a lot of posts about modems but it's still confusing more me. I'm searching for the most appropriate modem for a I9300 french operator Orange as my phone is under CM11.

The one I currently use (ZNUBML1) is very bad !

Edit : wrong thread, sorry
[Galaxy S III General] JJEgan:
Go to the modem threads .

Or flash the French Orange modem whatever that is .
[Galaxy S III General] sixstringedmatt:
I am on a Verizon unit, but know this is a huge thread and was hoping you all could help.

I'd like to sell my S3 as I just upgraded to a Moto X that has a nano SIM on VZW, so I can't re-activate my phone to verify it is working fully (the SIM card in the S3 says it's already activated, since it has my phone number info).

I recently went from CM11 to 4.0.4 and want to ensure before I sell that the IMEI is not corrupt on the device. If I was able to call Verizon customer service and get through, does that mean my IMEI checks out and the phone is ready to sell? IMEI shows up in the status settings as a valid number, but anything else I can check short of having the buyer put in his Verizon SIM? I would hate to have them come and realize the phone's botched.

Many thanks!

I hope somebody can help me here.

Im on NA5 4.3 with MK6 modem.

I want to downgrade to MH4 4.1.2 with MG2 modem.

If i downgrade will I lose IMEI.

Is MG2 is also a EFS V2 modem.

Correct me if im wrong.
[Galaxy S III General] dabyd64:
MG2 is an efs v1 modem as far as I kbow.

It will be OK if you flash MG4 modem after that ROM, but doing a backup before flashing won't hurt;)

Network problem

Hi there,

I have got a problem with my i9300. I updated from 4.1.2 to 4.3 and now I have no network connection on my phone.

It shows me "Data is not registered" when I want to call to somebody.

The weird thing is that I didn't lose my IMEI - it didn't change.

I flashed a tons of ROMs (officials) , 4.0.4, 4.1.2, 4.3 Nothing helped me. I also flashed this v2 pack from this thread, didn't help.

What can I do? Please, help me.

Regards.

Thanks for your help, but I don't know what to do. I lost mij EMEI, so I had to use the UK firmware (Androidversion: 4.1.2, baseband version I9300XXEMG4, kernelversion: 3.0.31-1314436 se.infra@SEP-108 #1 SMP PREEMPT Tue Jul 16 20:28:36 KST 2013, buildnummer JZO54K.I9300XXEMG4) (something with the basebands), but now I see there is a new firmware for my country. I thought maybe this one (see my last qoute) has the same basebands as I am currently using (the UK one). My question: Should I flash the new firmware available for my country or do I still have to use the UK one. Thanks!

I just want to say thank you so much to the OP! Last summer i had a major factory mode issue with my phone and got so fed up i bought a Nexus 4 which was on sale at the time. Now the time came where i got fed up with the Nexus 4 poor camera, battery life and lack of expandable storage. My S3 had a 6000Mah extended battery aka 2 days hard usage. I had to do the extended factory mode option, deleted the factory folder, wipe and install rom, and do the thing in termulator and it works!!!!

Wow. Same symptoms with Galaxy note 2 AT&T. I would love to know how to fix it. When I dial out it hangs for 30 40 sec. Signal dissappears and it hangs up. Right after that it signal appears again. Wifi, data, messaging all work like a charm tho. Crazy man
[Galaxy S III General] Paresh Kalinani:
I recently rooted my S3 via the CF Root method. Flashed CWM Recovery 6.0.4.4 via Odin.

That's it.

And now this weird problem-

My network is lost anytime! And the phone even doesn't say "Not registered on network" or something like that!

My phone was working properly but my friend called me up on my landline number and asked me whether my phone was switched off because it said "the number you're trying to call is switched off". I also noticed that at time even the data connection was not working. NO! It's not that it didn't show it isn't connected to the network or the data is disabled! The signal in the status bar was of 4 bars as it is and there was this symbol of 3G beside it. I tried calling my friend but the call got cancelled! I redialed, I didn't hear anything and then again the vibration saying the call was cancelled! I called up on my S3 through my landline number which also said that it was switched off. I tried selecting my network operator manually, it said 'Registered on Network' but still I couldn't receive or make calls or use my internet data. The only solution was to reboot the phone after which it worked fine for a few hours. FOR FEW HOURS ONLY!

Now it happens at least 5-6 times per day and it has been important for me to check whether the data connection actually working and I'm able to access the internet or not because that's the only way to find whether someone can call me or not!

How do I fix this? Am I a victim of this IMEI problem? But I haven't flashed any Custom ROM or anything! Should I backup my efs now or is it too late and I've already damaged it.....................? :(

Noticed that I can't even access Samsung codes now.. dialing *#06# doesn't show up my IMEI number.

Know version of efs backup

Hi

I have searched a lot and no answers yet.

Is there any ways for me to identify the version (v1 or v2) of my efs backups? I have one made in 06/14/2013 but I am not sure if it is the v1.

How feasible is to downgrade v2 to v1, what are the risks?
[Galaxy S III General] k-semler:
It is likely, (almost certainly), a v1 backup, as I9300OXAEMG4 was released in July of 2013, (the release that converted the partition to EFS v2). V2 releases can read v1 partitions, but not the other way around.

Technique for your IMEI not remain corrupt. GT-I9300

Hello everyone,

I saw the procces for to repair file "/efs" in this forum, but I discover one form for " Not to corrupt" IMEI before and after flush rom "original". The process is very easy , only need to be root , root explorer and off course backup file "efs" , whatever ; is similar for all gt I9300.

I do it in my phone . The kernel , the room version , etc Is not important, THe important theme is the permision file "/efs" ...so that the rom file contain the archives for to change the phonecel ! . So do not forget it ! You have to give permission to the file /efs :

1. Enter to root .

2. Installing Root Explorer.

3. Installing terminal root.

4. In the terminal root to do( Root)

#chwmod 1001:radio /efs/nv_data.bin.

5. Reset cellphone.

6. Join it !!!:laugh:

Before to do all this you have to do backup from file "efs". This process doing that the file /efs secure itself.It. It is for android version 4.1.2 that have problems . Thank you.

Hi everyone. I had a major trouble with my phone previously and had this unknown baseband and null imei issue, with the whole phone in factory mode. Nothing really helped although the commands for the terminal emulator helped to get me out of factory mode. It's really a good read on the first thread. If I may, I would like to ask to add another suggestion as a solution which helped me got through my issue...I used samsung kies to restore my firmware back, instead of using the stock rom from the website, known for its slow download speed if you're a free user. It was a lesson learnt for me, backing up efs, the not-to-be-touched partition,etc. Now I will do all means to make sure i have a efs backup before anything,

I really hope someone can help me here. I have read till my eyes have bleed and my brain blew off the top of my head and raised a white flag but im still stuck.

A few weeks ago our new puppy decided to see how my faithful SGS 3 tasted resulting in a cracked screen. I put off repairing it for a while but eventually I got round to doing it. I had almost got the glass off the front when the puppy again decided to " help " dad. The result ...one dead LCD and me in a very bad mood.

So i stripped the phone down completely and took the damaged LCD off hoping to get a new one.

Then I found a white SGS 3 in my local pawn shop which had been reduced in price as they think it had been blocked, so I bought that one instead.

When i got home I took both phones apart and removed the motherboard and the sim/sd card holder from my phone ( which i know was working as I could ring it and had the blue light flashing away on receipt of text messages etc. ) I then put this in the " new " phone turned it on and had a working phone again, or so I thought :(.

I can not get a signal at all and when i go to settings in my rom ( Omega v58 ) and click on the mobile network I get the message " Insert SIM card to access network settings "

I also get this come up on the screen randomly

Could some one please please help me as this is starting to upset me.
