Just restore your backup efs! (Or let me guess you did not back it up)
Seriously though have you used the patched modem mg4 that is floating about I presume you have?
Here is a couple of links to look at >> http://forum.xda-developers.com/galaxy-s3/help/solved-upgrade-to-4-3-network-fixed-t2547450 << >> http://forum.xda-developers.com/showpost.php?p=43946365&postcount=15 <<
Also there is a efs thread I suggest posting your question in there.
Thank you but i had to downgrade back to 4.0.4 before applying the XEMG4. I also wish to know what causes this and if i am condemned to stay on 4.0.4?
Your efs folder is corrupted or incompatible with later firmwares that require efs v2. Only solution is restore a backup or a competent repair.

Hi, sorry if this has been answered, but I can't find it.
I recently combined two broken i9300's (one with a bricked motherboard (gets into download mode, product name blank, think it's SDS), the other with a smashed screen) by transferring the motherboard from the smashed one to the other.
It seemed to work fine for a while, but after a week the phone lost signal, showing no service. Rebooting the phone fixed this, however this has now been happening more and more often, and now doesn't have any service even after booting.
Does anyone know what the problem could be, and how to fix it?
Thanks.
EDIT: I managed to restore service again by flashing the stock ROM through Odin (was running stock already), but it lost it again after a few hours.

Check IMEI and serial if corrupted. If it shows your correct IMEI and serial then it's fine. Otherwise you may have an EFS problem.
Report back please.

IMEI and serial are both fine (non-zero and non-null anyway). IMEI matches the label from the smashed phone. However, it's connected at the moment (just re-flashed the stock ROM again). Will update again the next time it loses service.
EDIT: Just lost service again. Only took about 10 minutes after flashing. IMEI and serial are still fine. I also forgot to mention that the motherboard I'm using is from a New Zealand phone, whereas the casing/screen is from a French phone. Don't know if that makes a difference. I tried flashing a French stock ROM, but that gave me an unknown baseband and null IMEI. Flashing the NZ ROM again fixed that.
EDIT2: And another correction. IMEI and serial showed fine after losing service, but I then rebooted the phone. Still no service, baseband is now unknown, IMEI is null and the serial number is non-zero but different than it was. However, I'm sure if I reflashed the ROM again I'd have service for a few minutes, so it doesn't seem like the EFS is entirely corrupt. I'm scratching my head a bit at this one.

Judging from your last two sentences you actally have got an EFS problem. Just to clarify: you get generic IMEI & serial with every other ROM you flashed besides the original NZ stock?
Otherwise it might just be the modem not fitting the ROM, try another (if possible original 3-part stock firmware), but make a Nandroid backup or save your EFS otherwise in case you need it later.

Not generic IMEI but null IMEI. Not sure about generic serial, not sure how to tell the difference. And I'm now seeing the same on the NZ stock firmware after a reboot.
Is a Philz Touch EFS backup sufficient? Anything else I should backup as well?
Well, since EFS is broken already it should be sufficient. To be on the safe site you can additionally save the EFS folder with Root Explorer.
If you have a working EFS you would need to save it with an EFS saving tool like 'Samsung Tool' in this forum somewhere.
Then you got to go through the EFS threads for i9300 and hope to be able to fix this.

I've already gone through all the EFS threads I could find. Haven't seen anyone with the same problem (sometimes it works, briefly, then it stops). Everyone else with the baseband unknown, IMEI null/null problem seems to have that all the time. Was hoping someone would be able to tell me what's different with mine.

How should anybody know from the distance? We can just give hints and point you into directions, now you've got to read & google and if you're
persistent enough you will solve your problem - as long as it's not hardware related.

Sorry, just meant that I thought somebody might have seen this exact problem before.
I think I've solved this. Used the repair NV data option (to fix broken baseband) in EFS Professional, and it seems to be working fine. Will see if it's still working after a few days though.
My best guess is that this was a file permissions error.

No, not fixed. Worked fine for a few days then the problem came back. Just tried a non-stock ROM (Omega) and same thing. Trying a CM-based ROM now (ParanoidAndroid), but not too hopeful.
Still don't understand why it works for hours/days, then suddenly stops. Rebooting it fixes it the first few times, then that stops working as well (and I get baseband unknown at this point). Flashing a new ROM always fixes it, for a few hours/days anyway.
Sounds like a hardware issue, possibly nand memory becoming corrupt hence why it works for a while on a fresh install.

Any workarounds you can suggest? Just had the problem happen again on cyanogenmod, so that didn't fix it.
Try reading the freezing thread in general forum, see if the memory test tool will compete after a full wipe and fresh install of a stock firmware.
Other than that only a new motherboard, as the emmc chip is damaged.
Hi guys, I must have read a hundred posts about this issue to no avail.
I recently rooted an old S3 GT I9300 using CF-Auto-Root and Odin. I was sure I backed up the EFS folder, but it would appear I didnt. Now I am runnning the Paranoid Android 3.0 ROM on the device with absolutley no mobile network/signal and although i have the IMEI written down the S/N seems to have changed to a generic 15 digit number as opposed to the original RCF**** or whatever it should be.
Ive tried Kies and re-installing a stock ROM which is both hard to get hold of and doesnt seem to want to unzip from CWM Recovery even after cl;earing the Caches and doing a factory reset. I've also tried re-writting the bin file using a hex code app and terminal with no luck, and EFS Pro only seems to make me think ive restored the EFS by backing up the already corrupt one and restoring that....
It is possible to rectify my EFS issue (nv_data.bin file I assume) with only a written down IMEI and no serial?? if so please advise... as Im seriously stuck and although ive considered using a friends efs folder im sure this is probably illegal...
HELP, Thankyou
oh..and...
It occurs to me that the guy to talk to is spocky12, yet i have yet to pm him pending your advice.... thankyou for any help i may receive..
Hi im also in the same position ive tried loads of stock roms for the UK as thats where i am... to no avail ive tried the original 4.0.1 rom all the way up to the latest 4.4.2 rom and each time the imei number is 0000999......... ive tried modem patches most of which are from looking through the xda site but nothing seems to work.... i could never back the efs up as when i had the phone it was in a constant loop so never knew which software/modem/firm it actually had on it as i could not get past the samsung logo. but since i have flashed latest android for the phone it will boot in fine just wont connect to a network and imei number is wrong ive been days trying to figure this out :crying::crying: Please Help!

Hi Dejay, its good to know im not the only one. have you tried using the Kies program to reinstall stock firmware, did that change anything? Also not sure if you tried this http://www.youtube.com/watch?v=JqLK_2I-SBM method but it didnt work for me, the HEx lines he refers to dont exist in my nv-data.bin.
Coincidentally, thats exactly how i acquired this issue, it stopped booting so i factory reset deviced, then backedup and rooted, then installed custom ROM and somehow lost backed up /efs .Im now showing an 000049 IMEI and tried modem patches, stock roms etc. and no luck. my serials all messed up too and i cant connect to any form of mobile network.
I just changed ROM again as i couldnt get the right Gapps to flash with Paranoid Android Rom 3.0 - now flashing Dirty Unicorns v3.8 from here and all working beautifully except no signal, wrong IMEI and S/N - I am by no means a PRO at all this and so im rather stuck like yourself..
Hopefully we'll be saved?!
Hello,
I have a big issue with my i9300. I flashed PDA: I9300UBUGNK1 Brasil version and I decided to root it using CF-Auto-Root-m0-m0xx-gti9300 .
After root the phone was perfectly working, but I uninstalled some pre-installed games which come with that Brasil version from sammobile and after I woke up after several hours I've noticed that there is no signal. In settings > phone info it says BASEBAND VERSION : unknown and IMEI : null.
I tried to flash again, I've flashed different version, nothing can help. The phone is fully functional WIFI works, only no signal, null imei and unknown baseband version. What the heck I can do before smashing it with a hammer?
And I'm talking about home fixes, as I don't have jig & other professional tools
There is no home fix for imei problems, unless you have an efs backup to restore. Take it to a repair centre and pay them to recode it for you, make sure it works on 4.3 before you accept it back.

As long as the phone is not bricked there should be a home fix... Hopefully
Nobody??
Managed to make it working using an efs backup from a different phone. Now I have to figure out how to put my correct imei instead of that one
Imei now shows 0049
This thread should be closed, indeed a very friendly and helpful community over here ....
A mod, please close this thread
Stop whining, you got the right answer the same day you asked.
Cloning your phone by using the efs backup from another phone is illegal and won't fix the problem anyway.

I didn't wanted to clone another phone and hijack it, please let's remain serious. I just wanted to fix ny efs and that's why I used a backup made from a phone which was broken and was sold by parts.
Now everything was fixed at service
Just a question about k-tool backup
After doing a backup with it I have 2 files
efs.img - 20mb and
efs.tar.gz which has 0 bytes and appear to be damaged as I cannot open it.
Is that efs.img enough in case I lose my imei again after a flash or what?
Hello guys, I had this same problem 2 days ago after flashing the GlamourS4 ROM onto my friend's S3. The flashing failed as it was flashing the modem with an "Assert failed" error, however it still reported that the flashing was successful. On booting the phone it had a null/null IMEI and the baseband was also unknown. I even posted about it on xda.. Yesterday, I found a way to fix both the nul/null IMEI and the unknown baseband. I figured that if I flashed modems onto the phone that the baseband "unknown" message would be fixed, and in the process also fix the IMEI. I therefore searched for patched kernels and modems for it. I came across this page that had patched modems and kernels for the S3 running Android 4.3. I flashed the modems and kernels found on the page with CWM 6.0.4.7 one by one. I went through 6 zipped files before the seventh one fixed my IMEI null/null and baseband "unknown" errors. The one that fixed it was "Patched_XXEMC2_Modem.zip". The six I tried at first changed the IMEI from null to 0049XXXXXXXXXXXXX/XX. The seventh one fixed both problems well. IMEI is well now and the baseband is too. Try flashing the kernels and your phone shall be OK like mine.
Null or 0044....... imei, only repair on service with box and tools... In Serbia, cost 10 euro. Good luck

Hello guys.
So I was flashing custom roms before, and just today realised that my IMEI got lost.
I tried restoring it by this method: https://forum.xda-developers.com/redmi-note-3/how-to/flash-recover-efs-snapdragon-t3406789https://forum.xda-developers.com/redmi-note-3/how-to/flash-recover-efs-snapdragon-t3406789
And now my phone doesnt recognise the sim card and I dont have signal.
I am currently on AOSIP 5.9, my phone is redmi note 3 pro.
I have few nvram backups, from miui and cm13, what can I do to restore my EFS partition and get back my IMEI?

Don't worry. In my case, IMEI were not erased, even then sim networks weren't showing up. This happens when you downgrade or upgrade without required firmware (atleast with me). Try to flash latest miui firmware or, you can try cm14.1 firmware.

I can not help you with a solution, but I'll tell you that I have also lost IMEI, sent it on service and came back with another IMEI, not that one on the box. Since then, my phone acts extremely strange in any way, with random reboots, bootlops, errors on flashing different roms... Its just a pure hell. I don't know if the reason is that it has another IMEI then the original or its just a bad hardware, but I'm considering trying replace it with original one...
IMEI is the same on both SIMS for me. Sadly, I haven't checked before losing it.

@{s3rious}, @apriores, @Moody Abed, Guys I have had a lot of history with bricking and loosing IMEI, mac address, fp sensor issue, earphone issue with RN3. There were many times, when I thought, that I've damaged the hardware and it is needed to be sent for service. But let me tell you, most of these issues can be solved by making a few changes in the software. First of all, try to go to the latest global developer miui rom. Manually flash the modem partitions. Restore efs. Try all of these. You'll surely manage to correct the issue.

when I tried the first option, I completely lost my connection, the phone didnt recognized the sim. And then I made a restore with trp backup of efs partition and got my signal back, but IMEI was still missing.
After that I tried the second option, but I have only 1 IMEI, not 2. And in order to press start you need to have 2 IMEI-s, so what should I do?

Aah nevermind. The IMEI 2 is same as the IMEI 1 unto the last two digits. For me, IMEI 1 has 23 as the last digits and IMEI2 has 31. Apart from that everything is same. So, you can try putting some similar values to IMEI 2.
And, I'll tell you what. One time, I lost my IMEI and I didn't had my box with me. What I did was I made a clean flash of the miui global dev (any miui may work), and I had them back. Then I don't remember exactly, but I think I made the efs backup and .qcn backup and noted the IMEI on sheet and then flashed the custom ROM. Then restored the efs or qcn or maybe I entered the IMEIs manually, following the same tutorial I mentioned earlier. I had my networks working on the custom rom.
Good luck to you.
