Hi there, please help.
I update to 19300XXEMC3 but it keep on software updating (2 more time) and it download the latest one, which turn out to be I9300XXEMG4. Now it can't make any more calls, only emergency calls and no date. I read something about the EFS partition, members were talking about saying something about the IMEI not reading and you cant downgrade back to an older Firmware, but when enter *#06# the IMEI shows up normal. Is there any way to fix this problem or do I have to wait for an update like 4.2.0, etc? or Is there any ways I can make data/calls work on XXEMG4? or Is there any ways I can go back to my stock Firmware 4.0.4 I9300XXBLH1?
Thank you in advance.

It's better to instal CWM on your phone adn then flash any Stock Custom Roms. May be then your prob gets solved.

Please read the faqs and guides first.
EFS
/IMEI is very important .

Hi,
I used Android 4.1.2 and CM10.1 - on Samsung Galaxy S II model I9100.
During a phone conversation it was hanged up, and the phone could not connect to the network anymore.
I got an error when tried to manually search for network operator, which lead me, after a research in the net, to find out that the IMEI of the phone is empty. I see also that the Baseband version is 'unknown'.
I have a backup of the efs folder and tried to restore it by manual overwrite it - with no success.
I also followed the guide to recover manually the IMEI from here: http://forum.xda-developers.com/showthread.php?t=1264021 with no success.
I tried to get back to a backup of the original ROM I used before (this time using ODIN), and now I get NULL/NULL in the IMEI and I still get Baseband 'unknown'.
Also re-installing the radio did not help. now when looking for network operator the error is different - now it is telling me that there is no SIM card.
the NULl/NULL IMEI and Baseband version is 'unknown' are still here and I still can't connect to the network.
last input: after 2 days of phone being unused - it suddenly got back to work, the original IMEI got back in, and it connected to the network. this happened without me doing anything, and it held for half a day, then the phone got back to the non-functioning mode as described above, again in the middle of a phone conversation.
I am out of new ideas, all related threads in here did not help.
Can anybody help ?
Does anybody know the reason for this issue?
Can tell what is the thing that is probably corrupted, and in case that the problem is with the files in efs folder - why doesn't a restore of the efs folder (including chown for nv_data.bin to user radio) did not help?
Thanks !

EFS is corrupt.This was a bomb waiting to explode.I suggest you to go back to stock JB 4.1.2 ROM (see my signature),and flash Apolo kernel.Go to recovery and restore backup.Do not overwrite it manually.Do it in Recovery.

Hi GamingDj,
First thanks for the reply.
I want to add more inputs and few questions:
Right now, after more then another day that the phone was not functioning - it got back to operate again, and again, without me doing anything that will cause that to happen.
During the last time that it happened, this held the pone in a working state for about half a day until it hanged up on me during a phone conversation I had - and the phone stopped working again, so I am not very optimistic about the phone getting back to work for good right now....
I have a bit more data that I forgot to mention before:
1. About a day before this problem happened, Avast anti virus offered me to update the Avast Anti theft software, this required root access and I don't know if it has something with the reported problem or not.
2. The efs folder was "handled" by GalaxSim Unlock, after the phone got locked due to official upgrade to JB. Originaly this was an O2 locked phone, then it was unlocked with a code, but due to the upgrade to JB it got SIM locked again and the codes did not work anymore, which caused me to use the GalaxSim Unlock application - that indeed unlocked my phone. I know that the GalaxSim Unlock application changed some data in the nv_data.bin in efs folder, but after it unlocked my phone it was working fine for about a month or more, so I can't tell that this is the cause for the suspected corruption in the efs folder.
I have both backup of the efs folder before and after the unlock operation by GalaxSim unlock application.
Can you explain in more details:
1. Why you suggest to flush Apolo kernel? is it in order to have the phone rooted? can you give a link for this kernel?
2. Restore backup from where? should I have a backup file that you point to? not sure what backups I have that may have data that I don't already use.
3. Does the new data help with debugging this issue?
Thanks again.

Hi,
Just want to update that its been about a week that the phone works without me doing anything, therefore not proceeding with the recovery process you suggested.
I will update if the problem will be back.
Thanks.
Hi all,
This is my first post i have a Samsung galaxy s3 gt i9305 4,3 jellybean which I flashed to 4.1.1 using Odin and then unlocked it using the service mode method that i found on here http://forum.xda-developers.com/galaxy-s3/help-i9305/sim-card-unlock-samsung-galaxy-s3-gt-t2185866 , it was on the EE network UK. I then brought triangle away to reset the binary download so i could system update, which didn't work and the counter is saying 1 so i cant update the system and a box comes up saying this device has been modified. My main problem is when ever i try and dial out it says mobile network not available. The phone is definitely unlocked as it doesn't ask for the unlock code anymore. When i first unlocked it GiffGaff came up but went again and i cant use data, text or phone.
Any help in solving this would be greatly appreciated it is driving me nuts and i just cant figure out what to do.

You were on 4.3 which uses EFS V2 and flashed back 4.1.2 which uses EFS V1. I think, you have corrupted your EFS, that is the reason there is no mobile connection. Do you have a EFS backup???, if not, please try to flash 4.3 again, take a EFS backup using tools available in xDA(search) and once back up is taken, you can flash back 4.1.2 and reflash your EFS. But why do you want to go back to 4.1.2? we have lot of wonderfull rom's of 4.3 and even 4.4....:good:

Hey thanks for your reply i will try that out and see if it makes a difference you are a super star thanking you kindly, sorry if i didn't make myself clear i do want to upgrade back to 4.3 after i have sorted everything else out for sure. I was on 4.3 but flashed to 4.1.1 to unlock the phone. I do not have a EFS back up which i have actually just been trying to educate myself on and now realise how important that part was, i just didn't know.
Why not ring EE to unlock?

Hi
Im really hoping someone can help me here. I have a samsung GT-I9300 the battery has been failing and recently it stopped booting.
I couldnt do anything with it tried using KIES but it didnt recognise the device.
I couldnt not get into it at all so did not back up the EFS folder.
I then had it working with 4.3 after alot of trial and error regarding the PIT file and creating a new partition.
I then reverted to 4.1.2 to try to upgrade it via KIES again but it still doesnt get recognised.
I now have the actual phone working but it cannot make calls as the imei number is 004999010640000/01.
I have a note of the correct imei but cannot change it is there anything i can do to fix this,as i mentioned i do not have a backup of the efs folder.
Any help is much appreciated im pulling my hair out with this.

What version android do you currently have on it? You basically need 4.3 or higher.
If that doesn't solve your issue you will need to take it to a repair center.
http://forum.xda-developers.com/showthread.php?t=2393289
I currently have 4.1.2 im on the ee service in the uk but am unsure which 4.3 i need
Since you upgraded your efs your early 4.1.2 cannot read it.
Read that link I gave you. Your need a 4.3 rom or modem XXEMG4or newer.
Here is a 4.3 rom for you.
http://www.sammobile.com/firmwares/1/?model=GT-I9300&pcode=EVR#firmware
No joy all works but i still have the stock imei number,i dont seem to be able to flash without a pit file using this each time make a difference?

Opps It seems I didn't read it properly.
If the 4.3 flashed ok and you still have generic imei then you need to take it to a service center for repair.
Hello People
Again, I'm with problems with my S3 since the one time decided to test a custom ROM which turned out to screw my IMEI and got to it back working with BOX in repair service.
I n order to see if the BOX fix did actually solve my signal problem, it was suggested to me in a previous post that I flash the same stock rom via ODIN. Before that, I backed up current EFS as well.
Unfortunately, it seems the problem wasn't entirely solved. Same as before: both my IMEI and S/N are untouched (S/N does not coincide with S/N in the back of phone) and though it says I have a full signal, I'm not registered in network and i can't make or receive calls, sms, etc. Even though I restored the EFS folder, nothing happens.
I really wish not to go back to repair service again. What else can I do about this? Many thanks and excuse my rant. Hope I was thorough and clear on the problem. I also have a EFSv2_basebands_opt4.zip file I downloaded somewhere in xda . Would that help?
Many thanks.

still, in phone info, imei and s/n are there. weird?

I would still like to solve the problem at its roots: to fix the "not registered in network" problem whenever factory reset or stock ROM flash via odin is done. That is simply not normal. I might be selling the phone soon and the new user won't most probably know he/she would have to apply a patched kernel or etc.. ( let alone about rooting the phone).
Basically, bring the phone back to it's original sound state before I tried out the custom ROM. What can I do about that?
Hope I'm not being annoying.. just trying to get to the bottom of things

Flashing modem with Ariza patch was bad idea. Your efs folder is screwed up now and you are addicted to constantly flash this dirty workaround.
If anyone have problems with registering in network please check your device serial number first. It must be the same as on the sticker under battery. If it's not then type *#0011# and check info under IMEI CERT. If there is FAIL info then you should use any box ie Z3X to correct phone's serial number. It takes only few minutes and is cheap. It's better long-term way than patching and permanently destroying your efs informations.
If you have backup then you should flash normal modem and restore original efs partition. Then find any GSM service center with box and tell them to fix serial number. It shouldn't cost more then 5-10 dollars.

I have never flashed the Ariza patch nor have I even mentioned it on my previous posts explaining the problem. Fixing the s/n issue is indeed adviseable, but paying to correct s/n using box here where I live is ASTRONOMICALLY expensive. They should answer for never having fixed it, but they won't. Here is a hell of a lot more than 5-10 dollars, unfortunately.
Believe me , I'm no happier in applying this sorry fix every time I want to factory reset or upgrade, etc; it's the only option I have left at the moment.
Those files you have flashed, I mean kernel and modem are patched with Ariza's method. It is called Ariza patch and it is latest solution you should take to resurrect your phone because it is a destructive one.
Sorry to hear that you can't repair it as it should be especially if you want to sell this device.

May i ask a few questions about your problem?
Which version were you using when you desided to use a custom rom?
Was your phone ever rooted before installing a custom rom (when you were on official)
Did you upgrade your phone before? (Official via ota or odin)

I was on 4.2.2 leaked version ROM some guy installed at a repair service some time ago when the phone belonged to my mother. I was actually rooted using the CF AutoRoot method, with Philz CWM recovery. I decided to change to a custom 4.3 without having changed first to a stock 4.3.
The problem came when, within the custom ROM's aroma installer, I ticked an option to upgrade the modem to some build I can't remember now and my signal became screwed up. I informed this in the developer's custom rom discussion thread about the issue to which he replied that the problem was that the EFS folder tried to convert from v1 to v2 and failed (this was when I learned of the whole efs version folder change since build XXX (don't remember).
I download a stock unbranded 4.3 ROM and flashed it via ODIN, believing that would solve the issue; it didn't. Finally, I became desperate and took it to a repair service where they used box. Apparently, late did I notice s/n was not the same as the one in the back of phone. I'm guessing that would solve the problem? I don't know.
i am sorry for your loss . i wish you had all that info you learned before a try and fail. now that your imei number is a clon number, and once a box tempers with that you cant go back even if you have your orijinal efs folder or backup. you should always have that 2 patched modem and kernel files on your sd card just incase. you can use custom 4.3 with the patched files and get a signal but you will always have some lags after some time because of the kernel. and lucky you samsung stopped updating s3 officially because patched files are only for 4.3. if you dont have a desire to use custom 4.4.4 kitkat roms then you are good to go and when it comes to sell the device, the price will be much lower then an original s3.

May i ask a few questions about your problem?
Which version were you using when you desided to use a custom rom?
Was your phone ever rooted before installing a custom rom (when you were on official)
Did you upgrade your phone before? (Official via ota or odin)

Well, actually, IMEI didn't get cloned; of that I'm certain. IMEI is just the same as it was before I took it for the first time to repair service. It was the S/N that got changed somehow. Should I get them to correct the S/N, and use the original EFS folder (I found it, i think), would that correct all problems?
S/N number is the same with imei number as when you dial *#06# . And as i said before you cant go back even if you have your original efs folder. Dial *#06# and check your imei number from an " imei check site " you can find on google search. That will tell you what i mean.
There are: IMEI, device serial number and Android serial number. First two numbers are on the sticker in battery Bay. They must be correct because are used to authorize IMEI certificate.
Samsung's IMEI begins from 35.....
Serial number usually from RF......
If you see serial number in HEX format in phone's info section, something like f1abcadef1.. than it is android not device serial number and this mean troubles with authorize SIM card in operator network, even if it shows proper signal power.
I don't know there is any secret code to display serial number but there is plenty of phone's info apps in playstore which displays this alphanumeric string.

Hello all,
I'm net about mobiles editing stuff, well I'm from Kuwait (don't have a specific firmware) I bought my mobile from Kuwait but as I remember it was have the firmware of South Africa and the latest update till 2 days before was 4.1.2.
I decided to upgrade it to 4.3 and downloaded a firmware (I9300XXUGNB6_I9300OJVGNB3_XSG) and it work But I didn't like that version, so I tried to downgrade to 4.1.2 again so I used Firmware of South Africa which I downloaded online But I faced a problem that there is signal But I get a message that Network is not recognized.
I tried to use these below firmwares But they all not working
I9300XXELLB_I9300OJVELL3_LYS
I9300XXEMD3_I9300OJVEMC1_XFE
I9300XXEMF6_I9300OJVEMF1_KSA
I9300XXEMF6_I9300OJVEMF1_XFE
so I again used this one (I9300XXUGNB6_I9300OJVGNB3_XSG) which is now also showing a problem that :
1- when make a call it start with speaker on
2- call disconnect by itself
3- if received a call on waiting, it turn the speaker again on for the current call
4- it used a ringtone song by itself.
so is there any way to get it work again by the old version 4.1.2 without any problems ?!
I used to format cache partition and make reset to factory after every time i make a firmware
No, you have to use 4.3 as the efs changed format from EMG4 onward.

thank you, but is it possible to backup EFS files from another mobile same model and restore it to mine ?
what about the problems which I mentioned that I still face ?
No it isn't possible. The rest of your problems sound like corrupt framework, reflash with only the latest firmware version and factory reset.
