Currently on Checkrom XWLA4 2.3.6 with Speedmod kernal.
Last night I performed a Titanium backup and a Nandroid backup in preparation for an upgrade. I had previously performed an EFS backup sometime back. I didn't perform the upgrade, just completed some backups. Anyways over night something seems to have gone wrong with my phone. I wake up to find that it's showing there's no SIM card detected and then when I checked baseband version and IMEI both are showing unknown as well as a bunch of other fields.
I've tried a number of ways to restore the EFS folder. I've tried GSII_Repair, EFS Pro 1.9, kTool, and a couple of manual methods. All of which give the same result.
Some strange things that I noticed, I have an EFS folder inside of an EFS folder. The /efs folder seems to have less files then the /efs/efs folder. Also /efs/efs folder was the fold that had the .nv_data.bak and .nv_data.bak.md5. Not sure if its suppose to be that way.
Wondering what the best way to try to get my phone up and running would be.
Thanks,
Lu.

The problem:
(a) You performed nandroid backup in CWM recovery while your phone was connected to the charger. This is a known bug of almost all versions of CWM recovery.
(b) Baseband missing means that your Modem was wiped off which happened as a result of the bug in (a.)
Further Explanation
a. this has nothing to do with your /efs folder
b. If baseband is missing then the phone can never read your IMEI, hence no network
Possible Solution
a. Download Modem (CWM zip format) of your choice. If you already have a modem then, skip to next step
b. Disconnect your phone from the charger
c. Boot to CWM recovery
d. Flash modem.zip you downloaded
e. Reboot phone
check your phone info after reboot (give your phone about 5 minutes to settle down), your IMEI, network etc should be back now
good luck

it was definitely plugged into my usb port charging at the time. just tried what you recommended and still the same issue. i wouldn't be surprised if everything that i tried today with the efs folder made it worse.
any recommendations? would it help if i tried a fresh install of xwla4 (2.3.6) or something newer like xwlpg (4.0.3)?
really need to get this fixed. any info or step-by-steps are greatly appreciated.
thanks.

You shouldn't have messed with your efs partition after the issue came up. it's suppose to be the last solution and not the first one.
ok.
try this:
-Remove your SIM.
-Reboot to CWM recovery
-Flash modem
-wipe cache partition
-wipe dalvik cache
-reboot phone
-Allow phone to stay for 5 mins.
-check your phone info, check IMEI
if both are back fine, just reinsert your sim and continue normal life.
let me know what happens

No problem. We learn everyday.
please provide answers to the ff questions:
1. Is your baseband showing now?
2. Is your IMEI back?
3. Goto Settings > About, in your phone and post everything you see there.

Not sure what happened or how this happened but while I was retrieving the information from the About Phone screen the baseband was showing unknown and then once I glanced back down to get some more info, it just appeared and within another few seconds I got my IMEI and cellular services started working!
Thank you very much kind sir! Greatly appreciated!

When you have this kind of problem, messing with /efs should always be the last solution and not the first one.

Thanks for the advice But what other solutions were there? I thought back to Sammy was the last resort? Is there any constructive feedback? Or just dissing?

in your own case, where baseband and imei was missing, changing anything in the efs comes last because, if it's other thing related, flashing modem , firmware and things like that should fix the problem.
Then the last thing is messing with /efs partition.
Why, because, efs partition is not touched during flashing of ROM/firmware. It contains sensitive files, and should only be modified as last resort.

I did a back up on sd and pc. Before. I had only flashed from rr 2.6.1 rom to a jb rr rom after a few days of not changing any thing it came up network locked enter code etc. Whilst out driving so nothing I changed iko. Now it still changes imei but I have a stored working backup so I jus restore that and reboot. Would a modem and rom have to be compatible? I've never changed my modem do I need too and is it flashable? thanks
I only have these problems cos standard isn't different..

GII_repair (app), you must backup your efs first,
Or manually repair your efs folder by following the tutorial here: forum.xda-developers.com/showthread.php?t=1264021

This flashing stock, did you do it through CWM or ODIN? If you have not tried ODIN yet I would go that route, could just be you need a stock modem.

i am such a tard.. i havent backed up the efs... i did so now after the mess ... i believe there must be someone with tips and a small hope, btw restoring efs make no difference at all, as dont have correct files.
The EFS is fine if you have IMEI, if you have only flashed each ROM once through ODIN you have hope. Try an ODIN flash again. Can you get to recovery to do full wipe first?
Try EFS Pro Here and download to your PC then run it. You will probably need to use your own wireless to get Busybox (free on Play Store) and run it on your phone - if the phone will not go to wireless, DL the files to your PC then copy BB over to the phone in Windows Explorer and run it on the phone.
Then run EFS Pro on your PC (with phone connected by USB, but it will prompt you) and there are a couple of options there to try to see if you can recover things. (NV Recovery and Repair NV Data) - I think the NV Recovery uses info on the phone (.bak file) while repair tries to rebuild the info.
Good luck. Maybe read through the thread first or contact the thread OP if you have questions about EFS Pro processes...

I don't think this will help with the Serial issue, but maybe for the service all you need is the APN/Service info from Vodaphone? Go to [Settings] [More Settings] [Mobile Networks] and check both Access Point Names and Network Operators.
I flashed a ROM and found I had problems so I went to a Telstra page, entered my phone number and it sent me a text with a security code - when I entered that it sent me an install that connected all my services again. Maybe Voda has similar? Or even just a page with APN info?

guys help me out... i am stucked ... any tips? i am willing to try "almost" everything to make it work.
Beyond what I know so far, sorry. If it was me I'd be making sure I have back-ups of everything I can think of (Data, System, Nandroid, EFS) then I would start from clean phone - wipe everything in recovery, factory reset etc. then load as close as possible to the original Stock for the phone. If that doesn't do it, with official stock and counters etc. I'd go to vendor and ask what gives. I'd start with the service provider and if they can't help, phone vendor, then failing that, Samsung.
Maybe some of the more experienced here can assist otherwise...

Difficult to give you any help, you haven't give any information on what went wrong.
Try posting what happened, if you have matching imei under battery to phone info and which modem version you flashed last.
You do have efs backup, right?

Does your IMEI match the one under the battery .
If not restore your backed up EFS folder .
Fail to backup its a service centre paid for repair .
Samsung Galaxy S3 General Sticky Roll-Up Thread ***Stickies found here!
If imei and serial number are not corrupted. Check your APN settings. You may want to flash stock rom to see if that works. Backing up efs folder highly recommended.

Dial *#06# in your phone's dailer and if your IMEI matches the IMEI on your phone's box or under battery then its something else.
If it says something like 0049xxxx or null or 0000... Your IMEI is corrupted.
In the case of corrupted IMEI you must have a backup of your EFS folder in order to restore it. If you have backed up your EFS then you're safe. If not.... Only Samsung can fix it for you, provided you have warranty left.
I had the same problem.. my IMEI changed to 0049xxxxxx by installing Custom Rom. Got it fixed for free by Samsung PM me if you want to know how.

No idea really... but if you know how to flash a stock rom via ODIN you can try that. If flashing back to stock again doesn't help then you probably need to send to Samsung for repair.
No service as per the basic guides stickied in General section .
Please check your IMEI is correct if not restore your backed up EFS folder .
No EFS backup = no fix .

I've just falshed a official firmware rom again , and still no coverage but at least it recognizes the sim .. If I have this new OFFICIAL ROM , and Flash Counters are reseted , I can go with it to warranty ?
If you have followed all the steps in the guide then you will probably get a warranty repair .
jje
Hi !
I'm sorry, , either you flashed it on Odin with "Clear EFS " box ticked, either you flashed firmware for wrong device. (Ex: i9000 for i9300. )
Anyway if you didn't backup EFS the only issue is Reparation Center.

you might be able to restore service if you flash an MG4 or MG5 official rom through Odin. This is only if you previously used an MG4 or MG5 rom and then flashed some other rom which uses an older modem . read this http://forum.xda-developers.com/showthread.php?t=2377731 and http://forum.xda-developers.com/showthread.php?t=2393289

alexalghisi, can you go in Phone Information and check if you have baseband?
If no, warrently, no luck.
In the black box the phone or modem is Mc2. This is an older modem than MG4. When a ROM that uses an MG4 Modem is flashed , it alters the files in the efs Folder making the folder unreadable for earlier firmwares. If OP had ever flashed an MG4 or MG5 ROM . than an MC2 ROM would not be able to read the EFS. as it can only be used by the newer firmware that can read it. If the folder has not been corrupted than it should work.

please elaborate. what needs to be done? what was checked and needs to be unchecked?
After having S3 for some months, I decided to update it to 4.3.
So I searched online and saw some tutorials how to root and install costum ROMs.
I read few tutorials to be sure how to do that and after all went good and the ROM installed, One problem has rised: NO SIGNAL!
so I wiped all and installed a ROM STOCK.
After that the signal came back "half way". It's showing signal bars but I can't call to anyone, even after calling to my provider...
I just don't know what to do. Please help

well these tutorial you've read were either very bad or you haven't read them correctly, because probably you missed the important step of the efs backup. see therefor the stickies thread or the thousands of similiar questions here in the q&a.

That is your backup flash with odin
( When you flashed a custom rom it probably backed up your efs some roms backup by default)
I would just backup your efs you have at the moment just in case you have problems flashing. You will then be able to return to how your efs is now even though it is not fully working..
Or try this app >> https://play.google.com/store/apps/details?id=net.hellcat.droiddev.ktool <<
The phone has to bee rotted to use ktool?
I also understand from the link you did about the EFS that there are two types of base bands and if I have an efs backup that I did on V1 baseband so I can't restore it on a v2 baseband, so my conclusion is to get back to 4.1.2... correct me if I am wrong

good that you found efs backup
yes you need root. or you use the recovery philz touch to restore your efs (then you don't need root, but a custom recovery).
well samsung roms based on 4.3 need efs v2, so you have to go back to 4.1.2 to restore your efs v1 backup.
if everything is working again, I would suggest you to use oding to upgrade to 4.3, because then everything should be updated correctly (but keep your efs backup, and make another one, just to be sure)
then you can try out again custom roms based on sammy 4.3
So what is the best option to restore it?
Because before I tried (while 4.3 stock rom was installed) the flash it with Odin but Odin always crashed when I was uploading it to Odin.
With kTool I tried before but when I am clicking on the button it says that it restored but he didn't asked for directory, when do I need to put it?
The same story with phliz, I also tried with this and he don't asks for directory, only asking whan the ending if the file-tar to bin...

Just extract the efs.tar and copy its contents to /efs.

Where is this folder located? I can't find it
and does it for xTool and phliz recovery destinations for teaking the recovery from?
Edit:
I found the /efs. I dind't know that I need to use root explorer...
I exchanged the files with my back up and suddenly instead of 0049 IMEI I got 0000 IMEI.
I tired also to flash a modem and also didin't work...

Hmm... try installing another EFSv2 modem, then do the /efs copying part again.
Suddenly after so restarts, the IMEI got back
But... The SN now is 0000000000
You'll need to correct the permissions of the files you've copied. Try searching for someone who already did this and duplicate what they did.

Ok,
I tried something new. I flashed a new modem, backed up a full backup and then installed a costum rom 4.3.
the IMEI GOT BACK! And even the SERIAL NUMBER!
But I think the serial number is not good because he has 16 or 17 (I don't remember) digits (numbers and letters).
But still i have signal bars but can't make or receive calls he says: "No registered on network"
For the finalle, I tried ARIZA patch but he Is stuck on 0%...
here I stopped, I really don't know what to do.
Don't use the Ariza patch once you've got your IMEI and SN back. Maybe try flashing a new stock version of Android with a EFSv2 baseband so as to not go through the copying fiasco.
