Hi everybody,

I've got an international i9300, and flashed TEMASEK's CM11. The CM installer said that's the sim is missing. OK, phone switch off, taking out the sim and back, restart. SIM is missing again, and in the setting menu the baseband, and the imei is UNKNOWN. I made a restore from my nandroid backup (wanam's 4.3) and that was worked perfectly. Then i flashed the latest modem (mj9), then the cm11 again. The error was the same. Back to wanamlite, made a fresh efs backup with galaxy unlocker, then flash cm, and restore the efs folder, but the error still exist.

Anybody have some idea?

Thanks in advance...

I'm in the same situation: currently in S4 V9.1 Ragzdog's ROM and it's OK with MG4 baseband EFS V2.

I flashed Temaseks' CM11 and I have the"No network" issue.

I read a post of a guy in same situation but he had a EFS V1 backup; he restored it and CM 11 was ok after!

As I see things we all who have EFS V2 and no backup of EFS V1 , won't be never able to use CM 11 unless

somebody like Zuluman does a modem patch like he did for 4.1, 4.2 or 4.3 or the guys from CM would

want to figure out a solution for that .

I went to Samsung repairing centre for repairing but they did nothing as my S3 was bought from the Emirates

but I live in Europe and they repair only phones bought from Europe countries.

So JJEgan, thanks for your sharp replies but repair is not an option for me!

I hope for the best. Thanks to all!

Hi,

I just flashed Cm 10.2 for the first time. I came from the horrendous Sammy 4.3.

Now I noticed that my mobile Internet (3g ect.) is not working anymore.

I'm sure that has to do with the Efs thing. But I don't know what to do and I'm on the road for a few days. So I really appreciate your help.

I'm currently on the emg4 radio and I do have an imei. I do not have a backup from Efs1 (I did one, but layer I found out it didn't work), but I should have one from efs2.

thx
[Galaxy S III General] shanky887614:
best thing i did was send it away.

i sent my phone away wednesday night, they recived in on the thursday lunchtime, reflashed efs etc and then posted it back same day and it will be back with me tomorrow (sent me pics of it to prove its fixed)

now when i first tried with a proper Samsung repair center they refused to fix it and said would take 2-3 weeks to do it on warranty. in the end it cost me £30.

have a look at "riff box" and "z3x box" website, find there official distributor's website in your country and then send to them.

if they have the above two boxes they can fix easily (yes there are others, i would have bought myself but they would just have sat in a draw)

hello frnds ..i need help..

does doin nandroid back up using cwm on our oficial stock rom 4.1.2 rooted keeps efs backed up too? and if yes...does restoring of this back up solve our problem when ever we face a not registered on network porblem on any custom rom?

thank you...
[Galaxy S III General] manjumohangh:
I tried to find this, neither could I understand nor find the link..

Can you please give it to me?
[Galaxy S III General] boomboomer:
Official stock rom recovery does not have nandroid function, only custom recovery will do this.

Normal nandroid does not backup efs, only custom backup on Philz etc. EFS restore may not solve 'our' problem if you've mixed up your baseband and rom efs versions.

Suggest you read the first post again, carefully.

[Galaxy S III General] jhuff83:
I was referred to this thread by another member. I'm running a Sprint Galaxy S 3 and have a question about cell ID reporting. I'm on MOAR ROM and using Better Wifi App. There is a setting within the Better Wifi App that allows wifi to be connected only if the cell ID matches. When I go and check the cell ID within the app, it shows -1 for cell ID. Basically, with the app, you can tag cells say for home or work. Anywhere I go, the cell ID is tagged as -1 which of course is wrong. Attached is the image of what I'm talking about. My IMEI number shows in about phone and I have no issues with 4G connection or receiving phone calls. I'm not even sure if this thread is the right place I should be. The developer of Better Wifi thinks I have a bad radio but I just don't think that's the case. I have tried flashing new radio, updating profile, PRL, and doing the handsfree activation as well. Any clue what's going on here?

[Galaxy S III General] mohsinriaz:
thanks zuluman

i had omega 43.1 when i switched to CM10.1 ... got imei 0049 and no signals... tried everything but couldn't get it back.... then i had to get it fixed from local repair shop who gave me my phone with 4.0.4 ICS.... i am not happy using ICS... so i tried updating to stock JB4.3 BTU from sammobile.... it messed up my imdi again.... then i tried different roms, different modems... can't list them all... but no use...

finally i restored my nandroid to ICS and no signals... but then flashing zulumans MG4 got my signals back... but my s/n is still 00000....

my question.. is there any way i can update to JB now? :(

Thank u dude , but kinda late

Dude , i searched everywhere but i didn't actually notice this thread , so this problem isn't related to root and this is the reason lockscreen and other features aren't there , but my smartness "IRONY" i sent it to service :P but anyways thank u dude :D
[Galaxy S III General] mohsinriaz:
No lockscreen is due to corrupted efs folder according to my local repair shop. I'm not sure about that.

Bro. ..I have taken efs back from my stock rim both in in format and tar format...well if I loose my ime while flashing other custom rims which are of 4.3 android versions...will the same efs can be used to restore my efs on the installed custom roms. ..pls help....
[Galaxy S III General] maatsby:
the original EFSv2 package was updated to include a new modem, here: http://d-h.st/bnH
[Galaxy S III General] mohsinriaz:
you may restore your efs folder if backed up.

yeah i had that issue... upgrading to android 4.3 BTU from sammobile fixed my problem... but this didn't gave me my signals back... also my s/n remained 00000... but when i installed shiva ultimo rom 14 (or1.4) it fixed my s/n but took my imei away :p so i flashed 4.3 again. (fixing my imei but messed up my s/n again)

then i restored to my ICS 4.0.4 from my nandroid backup ... then flashed zulumans patched modem... my imei is fine now... but s/n is 0000 and i have my signals back.... i dont know how to upgrade my android now :( :(
[Galaxy S III General] ApriliaM3:
Just a reminder guys, for anyone that's not aware...

On XDA, we do not allow discussions / mods / requests etc. regarding anything to do with the changing of your IMEI

Please keep this in mind and ensure that the discussions here do not cross the line.
[Galaxy S III General] mohsinriaz:
thanks but you're not helping

is it illegal to repair your imei number? no ones saying anything about faking the imei... guys here want to repair their imei numbers,,... if thats also illegal then theres no point login in to this website. and if that legal... then you're not helping. thanks anyways
[Galaxy S III General] JJEgan:
Repair is not illegal .Changing the IMEI may be and discussion of that as said is against the rules .

And yes we get a number of i want to change IMEI posts .

As this is a Developers forum not a fix your phone forum suggest you look elsewhere if you don't like the rules .

Hi I lost my phone today. But I have the EFS backup. Can I somehow find the IMEI number in it?
[Galaxy S III General] Gonzakpo:
What about restoring serial number?

I have my IMEI alright, but my serial is 00000. Ariza patch solved it (old modem), but I would like to know how to repair this myself.
[Galaxy S III General] openflame06:
I've been researching this a lot since I flashed a rom and got a generic IMEI.

I took the phone to samsung repair centre and they said they couldnt change it due to being an international model.

There is only two ways that I am aware of that will repair your IMEI:

1. Restore from backup (if you dont have the backup you have no chance of restoring without mehtod 2)

2. Buy a Z3X box or similar device that allows you to directly write the IMEI

Considering the cost of a Z3X box, if you didnt backup your EFS folder I would cut the losses and buy a new phone.

Remember if you flash using CWM and do backups, a lot of the time you may have a copy of the EFS folder in a non standard location so check around for that just to make your life easier.

As has been mentioned here several times ONLY WRITE YOUR OWN IMEI - writing a different IMEI is illegal in just about every country and can also result in your network banning you from using their services.
[Galaxy S III General] JJEgan:
Remember if you flash using CWM and do backups, a lot of the time you may have a copy of the EFS folder in a non standard location so check around for that just to make your life easier.

CWM does not backup EFS .
[Galaxy S III General] Swamphound:
Philz recovery (cwm-based) does have an /efs backup feature.
[Galaxy S III General] JJEgan:
Yes but user who read the post CWM backups your EFS are in ignorance and expect that CWM has backed up your EFS .

Philz backs up your EFS will mislead many as they expect Philz to backup EFS in a standard Nandroid backup which it does not .

[Galaxy S III General] dzjoepy:
Dear RootSU,

You told me when there would be a new official update i could get back my official stock rom and baseband. I've read that KitKat will be available for the samsung galaxy S3 in january. My phone is now running on 4.1.2 with baseband-version 19300XXEMG4 from the United Kingdom while i should be using this firmware according to SamMobile and my country (The Netherlands)

So my question is: when KitKat will be available for my country, does (of how does) it update to the offical KitKat version for my country? So i don't have to use the United kingdom version any more and have a original phone. Hopefully you understand my problem. Thanks!
[Galaxy S III General] same-xx:
To hohaz: yes you can, but why you need to do so? There are easyer ways to find stolen phone. Try Samsung dive. And you have the box...
[Galaxy S III General] JJEgan:
The basic answer is yes .

Next full release is new 4.3 .
[Galaxy S III General] same-xx:
I try one more time try to read from the xda pages about the generig imei, then ask the questions. Imei is not in the modem. Modem only sends stuff, so to speak. Imei is in the efs files. And not only one. Please people read. You with the bad reseption: chancing only the modem won't help. Even you live in U.K. You can chance your software. Make good back up:s and try whole another software. Look match of your phone model examble: orane gt-i9300 or just gt-i9300 and go for it. It all depens how all software parts fit together not just one part. Hope you get some help from this. And you don't need to wait your sofwares release date.

---------- Post added at 03:37 PM ---------- Previous post was at 03:32 PM ----------

Ou I forget: you can get your original baseband back only by restoring original back up by kies or from Samsung repair dealership. But why you need it? What is the need for that?
[Galaxy S III General] Deniece611:
Hi there noob here,

If i get baseband unknown is that related to efs?
[Galaxy S III General] JJEgan:
Yes no

No modem
[Galaxy S III General] Deniece611:
Erm sorry but i don't understand that, means? Btw i got this problem when i flash any aosp rom. I have a MG4 modem.
[Galaxy S III General] same-xx:
I haven't look into your problem really, but yes some ways it does. But if your baseband is "unknown" your phone should be dead. And is it? I just ask because I too tired to read 80 pages text. Maybe we can think something to help you.
[Galaxy S III General] Deniece611:
Thanks, mate :D My phone wasn't dead. If i flash the Samsung based (4.1.2/4.3) rom i will get my baseband back. Only aosp based rom have this issue :eek:
[Galaxy S III General] same-xx:
Do you have any back up left? Usuallu when only baseband problem appears is when phone is locked and simlock gets opened. And I can't understand

---------- Post added at 04:17 PM ---------- Previous post was at 04:11 PM ----------

Sorry, why you can only upgrade aosp. Because I can jump between or have both ay same time. Take a couple of back up:s of your phone and chance kernel. Chance something that supports dual software, like siyah kernel or what you like. And put another lets say omega sonething 4.1.2 not the new one but some and try what happens.
[Galaxy S III General] Deniece611:
Yes i have couple of efs backup. I used to jump from samsung based rom to aosp based rom and vice versa before this without issue. This issue appear when i am stupid enough to flash DXEMB1 (efs v1) onto XXEMG4 (efs v2)... No doubt, my efs got corrupted and i forced to flash my original firmware. Ever since that, i can't flash any aosp rom, when i do i will get baseband unknown, imei null and no signal. :(

Btw thanks for your suggestion, i will try when i am free and give you the feedback. :good:
[Galaxy S III General] same-xx:
Ok download efs back up programs. New and old. Allso download sgs3 toolkit 7.0-7.5. Put software where baseband is ok in and make back up. Including sgs toolkit. Because toolkit can fix it. Because I had generig imei problem and I fixed it. Now omega 4.3 v51 and no problem!

Send it to a company that does jtaging

They solder cables directly to the motherboard and repair it, bad chip they will replace it

[Galaxy S III General] Deniece611:
From what i know CWM backup doesn't backup the efs partition.

Or you may try to flash back your stock firmware. This help me out everytime i lost my imei.
[Galaxy S III General] zuperxtreme:
Hey guys, I have the "0000000" serial number issue with no network. My IMEI doesn't seem to the same one as the one in the battery.

The issue started after flashing CM 10.2 from stock 4.1.2 I think. I read about the esf issue after flashing though... so my backups I think are already compromised.

I'm back to stock 4.1.2, with root and CWM.

I've tried the Ariza patch, but no luck. Emergency EMG4 modem didn't seem to work either.

I then flashed ariza_JBv02 via CWM (after re-routing)

No network error has gone but get no service message and IMEI in unknown

Restoring IMEI with ktool does nothing

Flashing baseband with EFSv2_basebands_opt4 EG MG4 then restores all as above correct IMEI Serial Phone number Etc.

i am getting a notification that i have a voice mail ?

Try to use another sim. Your sim might damaged. Or reboot the phone without a sim and then remove the battery and place the sim and boot.

I got a similar error once on my s2 and I think the reason was that I flashed a new rom with the sim inside. Not really sure though.

It was the wrong sim in the phone was an old payg one that had been disconnected

[Galaxy S III General] manemzjum:
First and foremost Make an EFS BACKUP

MG2+ will use EFS V2

That you are already using

4.3 UK BTU uses MK6 which is after MG2 which also uses EFS V2

So it should be fine I did have a problem to start

Download Rom

Flash via Odin

If when you first boot you have emergency calls only (not registered on network)

Root your phone again As below

Boot phone in download mode (Hold power home and volume down)

Download CF-Auto-Root-m0-m0xx-gti9300.zip extract and flash CF-Auto-Root-m0-m0xx-gti9300.tar.md5

Flash via odin (included in zip) Thanks to chainfire

Download recovery-cwmtouch-6.0.3.2-GTI9300.tar

Flash Via Odin

Download Patched_XXUGMK6_kernel.zip and Patched_XXUGMK6_modem.zip

Copy to root of phone Tanks to zuluman

Boot into CWM (Hold power home and volume up)

Flash Patched_XXUGMK6_kernel and Patched_XXUGMK6_modem

All should be good
