The only way I can get any service to my I9300 is to downgrade to ICS, flash Ariza Patch 0.5 and then delete my efs folder contents and copy and paste from my backup. When I upgrade to JB 4.1.2 I get no service/emergency calls only. I have tried flashing many modems/basebands and still no service. I have tried restoring efs backups in a few different ways e.g copy and pasting using a root explorer, restoring via recovery, restoring via Ktool. Still the same issue. I have also tried using Ariza Patch but this removes my baseband and seems to make the issue worse. Please has anyone got any ideas?

is your imei okay?
My IMEI and S/N are both correct..
Read the ariza thread. it doesnt work on anything released after July.
There are posts in there from zuluman, 1 contains a pre-patched MG* baseband you could flash. Another contains a file you can flash to patch your baseband.

just updated my rom and was messing about with kernels and now my phone hhas gone odd.
it works fine on vodafone(original network) but wont work on any other network.
it always shows signal but with any sim other than voda i get emergency calls only.
so iv had a look about on it and my imei has changed to what i believe is a test imei or something. i have restored my backed up efs and it hasnt changed. its still the same.
i have now put it back to official samsung firmware 2.3.6 then rooted it with cf-root kk5
baseband- i9100xxkl1
kernel- [email protected]#2
build number- gt-i9100-eng 2.3.6 gingerbread xxkl1 test-keys

i wasnt asking how i fix it, i was asking why its happened?
as in why did restoring my efs still leave me with this odd imei number?
If we knew how it happened it would not be a problem .All that is known is that it is a result of flashing roms .

Flashing the ROM has corrupt your EFS file that contains your phones IMEI number therefore changing it to a false one.Thats why we do backups.Not overly common but common enough.The problem now is to get back your original IMEI by correcting the EFS folder.WHAT type of backup do you have?TAR,ZIP,e.t.c.?
Odia has a good rep at getting phones back up and running.Worth a try.
thats the thing. i understand flashing rom can somehow corrupt the backed up efs but it cant when my back up was on my laptop.
the backup i used was an .img file generated by hellcats ktool app. i also restored it with this app.
i also have the .tar.gz efs backups that are generater automatically but how do i flash this, other than adb. id use adb but it seems to have got a little confussed on my laptop, and dont ever work since i got my sgs2 :/

Heres a link.give this a try.Its an EFS backup tool.Make a backup of your current(wrong)EFS folder in img or tar.It will appear in a folder called EFSProBackup.You need this folder to restore.Open the folder and delete the backup.Put your original backup you made that you have in your PC inside and use the restore option.this program supports backup/restore of img and tar formats so you could try and use it to restore your original ones.

download the release zip
Id try the img restore first:the option to format current EFS before restore is at your own risk.Please read carefully.
The Baseband problem started when I flashed ICS euphoria from toxic 9.
I tried stock>cm7 initials>ICS passion> euphoria>slim the same problem IMEI is 004999010640000 or unknown.
The efs folder contains lost + found folder and it cannot be deleted. I also tried EFS pro to restore EFS. But nothing works coz the nv_data.bin is used and generated by some process.
Help !!! I am stuck in froyo (The IMEI NO is correct and the phone works in froyo)
had a similar problem

I had a similar problem. So here's what worked for me. Used root explorer to overwrite the old efs folder on the current one. Then flashed a known working baseband and eureka!! my phone was up and running.
Hope this helps.
Solved it by deleting all the files in EFS folder and replacing it with back up files.
The phone should be in flight mode. Then restart the phone.
The size of the EFS folder changes from 5 mb in froyo to 11 mb ICS may be thats the problem.
After upgraded rom using Kies "from stock to stock" the phone worked 1 hour with everything after that IMEI number dissapear stand NULL if trying to check it, on baseband it stand UNKNOWN, and NO SIM . I have tryed with several roms, kernels and so on but modems CSC but still same problem. Any ideas?
Seems your EFS is corrupted. There are several threads with possible solutions but if it happened on unmondified (read unrooted) stock, I'd return it.
That should NEVER happen and MAY have been caused by a bad SSD.
If you were rooted running a custom kernel or ROM previously, check your internal or external sdcard for any EFS file. Usually in the form of .tar or .img.
If this was the case, there are several methods to restore this to your device.
1. [TOOL] Updated! 24/06/12 - EFS Pro v1.7.14 - Advanced '/efs' Backup, Restore, Repair!
2. Galaxy S III partition layout, basic EFS backup instructions included
3. Nitrality app
4. Search
If not, return for repair
I've flashed roms and mods on my Sgs2 since I bought it 2 years ago. I've bricked it a few times and I always managed to fix it by myself, I only asked for help when my WiFi stopped working and I couldn't get signal at all only emergency calls (Never found fix for WiFi).
Anyway, I'm facing a similar problem now with my IMEI, I had this problem before and I learned how to fix it but now nothing works.
I've used EFS Pro, Restored a nandroid, flashed a stock samsung JB ROM (even though I don't think ROMs do anything to efs) I used kTool from Hellcat and the only way to make it work is doing my nandroid restore (CM9.. old nandroid backup) and copy pasting my efs folder I have backed up, however, If I copy paste the folder using another ROM (thats how I always fixed my corrupted imei) it doesn't work anymore, It only works once after restoring nandroid CM9, If i flash CM9 Odin it doesn't work, any ROM I install gives me corrupted imei. this problem started happening since I flashed stock JB ROM, I NEVER could use stock JB ROM without losing my IMEI, and I wasn't able to put it back by copy pasting efs folder (always used to work when i had this problem) another thing ~ I used NukeWipe Script ~ before moving to Android 4.2.2 now I only can use my phone with CM9 from my nandroid and fixing the imei there by copy pasting my backed up EFS. If I flash anything else my IMEI gets corrupted and I can't fix it with anything! hoping for some help, I would like to know how much will it cost me to fix this, take in mind that I'm from Mexico and USD is pretty expensive here
PS: I also tried the tutorial of Recover IMEI in 9 steps and it didn't work.
When I restore my nandroid I have a corrupted imei and no signal, my nandroid doesn't have a file explorer so I download one from market.. how do I download one from market if i have no signal at all and corrupted imei? I don't know ... I don't even have the 3G icon or any signal and it says no service but internet works fine.

Back up your efs folder with another app like galaxy s unlock or something (some apps make a copy of the EFS folder while other apps make an image of it), copy them to your PC then flash stock with mobile odin and see what happens.

I managed to get my imei back, codeworkx helped me, all i had to do was restore efs and then flash stock GB check if i still have my imei then flash ics then check if i had my imei then flash the old rom i had (mcm 4.2.1) and i had my imei but ... i tried to update to 4.2.2 nightly and my imei got corrupted, can't restore it while using 4.2.2, I couldn't use stock JB because of this, im guessing this is happening in 4.2.2 because they're using new stuff from stock JB.
Any ideas?
Could be, tattoo EFS on your arm just in case.

So I tried to flash marshmallow update via Odin. It looked like it installed sucessfully but then when I tried to boot up, it didn't work so I have to restore the nandroid backup. After that happened, I literally have no IMEI and I think the cause of that is the EFS folder got overwritten from the marshmallow update.
I was careless and forgot to backup my EFS. The Radio seems to work fine though. Could anyone possibly grab a working EFS in a tar or .gz format so I can fix my phones mobile data?
My Phone is A Galaxy S6 (SM-S906L). 5.0.2 lollipop.
P.S. I don't have a Windows 7. I use a Mac. Any programs for a Mac that could possibly fix my phones IMEI?
OR, is there any way I can change the IMEI with a root browser?
