I flashed the new ROM (9100XWKDD_I9100XXKDH_I9100XEUKD1) and now in Recovery I see the error in the attached pic.
Is this normal? If not, how do I fix it? I've tried reflashing the ROM several times through odin with just the ROM loaded in PDA.
Code:
-- Applying Multi-CSC...
Installing Multi-CSC
Can't access to '/system/csc/XEU/system/'.
Successfully applied multi-CSC.
Normal. Well, I assume it is because mine does the same!
I managed to get rid of the error by flashing ROM I9100XEKDB which also finally gave me a list of CSCs to choose from. Before there was just the one (XEU) CSC listed.
Only problem is the I9100XEKDB ROM doesn't include a XEU CSC and when I flash back to the KDD ROM I get a similar error and only SEK is listed in the CSC list.
Code:
Can't access to '/system/csc/SEK/system/'.
After flashing the ROM with XEU CSC you need to format and the reflash the phone with the same firmware to get it back to XEU. This is how I did it to get back to XEU from some German csc.
After flashing I9100XWKDD_I9100XXKDH_I9100XEUKD1 I wiped cache and did a factory reset through Recovery. This brought me back to my original error but atleast I now have the XEU CSC, still unable to view or select any other CSCs via the Dailer.
I then performed a factory reset through the Settings menu. Same result as above. Also tried a factory reset using code *2767*3855#
Intratech, do you have the error in post #1?
I might flash the O2 ROM which has a different CSC and the back.
Edit: flashed O2 ROM (I9100XWKDD_I9100XXKDH_I9100O2UKD1) and same error during install and in Recovery. CSC menu only shows XEU, it should show O2 CSC.
Now flashing the XEU ROM for what must be the 20th time today
SOLVED
Fixed it
Found this thread in the SGS forum from where I downloaded the XEU CSC files.
In adb shell noticed the files I downloaded above were already there but in the wrong folder.
Files were in ./system/csc
Files should be in ./system/csc/XEU/system/csc
I don't know why files were copied in the wrong folders and if I flash the ROM will it happend again. If / when I do I'll update here.
The original files are in a RO filesystem. My linux mounting skills being weak I installed Root Explorer and extracted the XEU folder (downloaded from thread linked above) to ./system/csc.
Deleted the original files which were already there (listed below for anyone else with the same problem) and then via Dialer entered code *#272*imei#. Success, CSC XEU was displayed, selected, installed and phone hard reset. Upon reboot bootloader showed XEU installed successfully.
Code:
/system/CSCVersion.txt
/system/CSCFiles.txt
/system/SW_Configuration.xml
/system/csc/feature.xml
/system/csc/sales_code.dat
/system/csc/contents.db
/system/csc/customer.xml
/system/csc/others.xml
Edit:/ The fix wasn't permanent Reflashed the ROM and same error which is strange. If there is some thing wrong with ROM then others should have the same error. It can't be my phone.
Have you looked inside CSCVersion.txt? There's a whole bunch of paths for files. I think it would be wiser to edit it rather than delete it entirely and replace it with the one you suggest.
I checked the paths in CSCVersion.txt to see where the files should be. First time I did delete the originals and copy the downloaded XEU folder.
The second time I moved the original files.
If I can around to it again I'll rename the patch in CSCVersion.txt and see if that helps. Thanks for the tip.
I flashed the FW released today and back to the same error. As far as I can tell it doesn't affect phone in any way. Just no options to choose another CSC. It's stuck on XEU which is OK as I'm in the UK.
Still no correction to this ?
O get this error with the XEU KE7.
SOLUTION
I have found a solution...
I had the problem myself with can not acces to /system/csc/VAU/system/
Download "Root Explorer" and Install
Make sure you go to the main folder (not sd cards)
click "system" then "csc"
The file system in there is Read/Only, so you must make it Read/Write by clicking the Mount R/W, it will become Mount R/O.
Now press the menu button and click "New Folder"
Make the a folder you need, Which in your case's it is "SEK" or "XEU" then in that folder make another one called "system"
All those folders are case sensitive i think... just do it in case.
Now... On all 3 folders (csc, SEK/XEU, & system) touch & hold the folder till "options" appears, then click "permissions"
and tick all boxes.
Abracadabra, hey presto... The problem will be gone now!
.......I'm not entirely sure why this problem is out there or what it does as the folders seem to stay empty, but it WILL fix your problem. I am only new to android but i love problem solving
----Not sure if permanent or not but easy as..
Hope this helps...

PrinceWicked69...Just logged in to thank you for your solution & say that you are the BEST!!!
Wish i would of saw this ealier, has the same ish issue with getting back to H3G.
Error very like your own.
Factory reset didnt fix it for me either, i tryed setting full write access on the csc folder (i didnt create the folders needed)
In the end the thing that fixed it for me was formatting the /system part which isnt normally wiped, error still appeard but i was then back on the correct region code.
When i just changed it using a csc file, it showed on my phone but when plugged into kies still was showing up as kor.
I have no Imei, No baseband, No reception (obviously)
ive been running cognition 1.51
and have downloaded csc selecter or something similer (that never worked) but i think that may be the issue when i opened it..
But i was wondering if there is a fix for this yet? or if someone can help me with resoring my phone to factory including the format of the efs folder?
ive searched for help about this, but noone has seemed to come up with a solution..
any help would be greatly appreciated

Just reflash modem.
If you didn't back up your efs folder, you might be out of luck. Try flashing the stock firmware for your provider and see if that helps.

all the flashing i have done over the past year with my sgs i9000 and now sgs2 i9100 i have never seen anything todo with efs.
so no i havnt backed up that folder, that cant be the only way to fix this?
i have looked in my efs folder and there is some files with .bak in them so im thinking some of the roms ive flashed in the past may have done a backup or something?

If you are missing baseband, there can't be imei either so flashing modem should restore it.

It means you still dont have modem for some reason.
If you have flashed new kernels recently, go back to kernel which worked and then reflash modem.

When you changed CSC, Your IMEI got corrupted. Only way to restore is efs back up or reverting back to original firmware. This should work ...
If not , You may try this one , http://forum.xda-developers.com/showthread.php?t=837239
I was able to solve it using this method. You need to be rooted to do this ...
This will void your warranty ... so be careful.
I would definitely not recommend using a i9000 method of getting the baseband, imei back on a i9100.
The EFS folder contains critical files for the IMEI, Baseband, serial number of the phone etc.
Check in the Q&A threads and in here someone else also had the same issue and they managed to resurrect their phone with some developer support.
Good luck, only other option is a repair job and just say kies crashed through the firmware update and now the phone doesn't boot.
Please use the Q&A Forum for questions Thanks

if you arent using a pit file dont touch the re-partion box or your will screw your phone completely and dont tick the EFS box either although now that doesnt matter as its already to late.

After 2 days and a lot of head scratching i've managed to finally get my phone back after a random corruption of my /efs folder... heres what i did:
the important part: you need to be able to access /efs with root explorer etc. and check the 2 files; .nv_data.bak & .nv_data.bak.md5
in order for this to work, these backups must be dated earlier than their .bin counterparts... in my instance, the .bins were modified sep 14th 2011 @ 09:45am (the time i rebooted the phone when i noticed i had no signal and the corruption occured), but my .bak files were both dated dec 31st 2010...
in adb shell, i ran
Code:
su
busybox tar zcvf /sdcard/efs/efs-backup.tar.gz /efs
i then downloaded 7-zip, used it to open the .tar file
i deleted the corrupt files;
nv_data.bin
nv_data.bin.md5
i then renamed;
.nv_data.bak > nv_data.bin
.nv_data.bak.md5 > nv_data.bin.md5
after closing and saving the changes, i then went back to adb shell and ran
Code:
su
umount /efs
mke2fs /dev/block/mmcblk0p1
mount -w -t ext4 /dev/block/mmcblk0p1 /efs
busybox tar zxvf /sdcard/efs-backup.tar.gz -C /
reboot
and voila! i was prompted to select my network provider, check status and all my IMEI, IMEI SV and other info was back to normal!
hope this helps someone out there, as i had a hard 2 days trying all sorts of different methods to get this working and was getting to the point of giving up...
good luck
Dickie.
Original post
right, i've been banging my head against the proverbial brick wall all morning over this... this is the score;
This morning i had no signal - 0 bars with a little x from memory
i switched it into flight mode, thinking when i brought it out it might reconnect
when i entered the power menu again, the flight mode button was greyed out (but it said it was switched on), also 'Call' in settings is greyed out, 'flight mode' is UNticked in 'wireless and networks', and trying to enable bluetooth returns an 'In flight mode' message...
reboots, cache/dalvik/full wipes, reflash of rom, flash of stock from odin inc. modem etc all do nothing...
In settings>about phone>status i am missing a lot of info, including phone number, network type and IMEI/IMEI SV...
i can enable wifi, and i downloaded an airplane mode toggle widget, which re-enables 'call' settings, bluetooth, and replaces the aiplane symbol with a circle with a cross through it...
I'm pretty stuck at this point and all i can think is that perhaps the EFS has become corrupt... anyone got any ideas?? all suggestions appreciated... in the mean time i'm going to look into the EFS stuff which i have no idea about yet lol
cheers,
Dickie.

yes you have corrupted /wiped your EFS or IMEI ,
If you backed up your EFS its not a problem just restore .
Plenty of restore EFS posts around broken IMEI etc .
jje
I'm looking in the EFS folder now, all seems to be present, but i am missing my IMEI (*#06#)...
not sure how this has happened, not done anything recently... very strange... but it does seem to be specifically the IMEI as my macs etc all all there and ok...
not backed it up so i'll see if theres a way around it :/
Cheers,
Dickie.
This happened to me 3 days back. Was sure I needed to send it in for service (reflashed and everything without avail) but then someone mentioned the EFS folder corruption issue.
Thankfully, I bumped into Rawat's thread a few weeks prior, and promptly backed up my EFS then.
It only took about 3 minutes in the terminal to fix the problem afterwards, no pc needed.
No EFS backup would usually mean a trip to Samsung service.
I got the same problem sice yesterday... tried all with the help of some guys here but nothing helped!
@eiraku: Do you like to explain me how you fixed the issue in the terminal, because my was /efs folder was also backed up but overwriting doesn't helped
ive just realised, my nv_data.bin & nv_data.bin.md5 have todays date in root explorer, i'm guessing thats a last modified date and that happend during the time in f*cked up, but the nv_data.bak & nv_data.bak.md5 are dated 31 dec 2010...
does this mean all i have to do is rename those backups and all should be sweet???
cheers,
Dickie.

Sounds hopeful.
I'd suggest you take a copy of those backups & put them on an external device before renaming anything.
i took 2 backups of the entire /efs folder, then renamed the bak files to bin, but i'm having trouble copying or pushing them to /efs...
anyone know how to mount it as r/w, i cant through root explorer and not sure via adb
any help appreciated...
Dickie.
---------- Post added at 06:24 PM ---------- Previous post was at 05:40 PM ----------
ok, i have tried the following:
busybox umount /efs
busybox mount -o rw -t ext4 /dev/block/mmcblk0p1 /efs
busybox mv /efs/.nv_data.bak /efs/nv_data.bin
busybox mv /efs/.nv_data.bak.md5 /efs/nv_data.bin.md5
then when i check with root explorer all appears correct with the baks gone and the bins dated 31 dec, but upon rebooting its all gone back to the way it was before...
again, anyone got any ideas??
Dickie
Did you found a solution? I'm thinking about going to a service center
i'm trying to work out how to get the damn /efs folder to remain r/w...
everytime i change the files, moments later its reverted to what it was...
just trying a different insecure kernel to see if that helps... even sometimes whilst i'm deleting/renaming the files it suddenly becomes read only again...
really wish someone who knew how to make either an update.zip or an Odin flashable tar could do so with my renamed .bak backup files to overwrite the original bin files...
Dickie
happened to me but the problem solved in a couple of hour without doing nothing
tried making an update.zip but i get a status 6 error... stuck again...
could anyone take a look at this for me?? ive been on this almost 18hours and im tired and need to sleep...
again, any help appreciated!

This happened to me whenever my phone restarted after cleaning the battery stats with Battery Calibration app (by NEMA) from App Market. At first, I restored my nv_data.bin file that was backed up (efs backup), but it continued to have same problems for next few reboots...
BUT!
I believe I have a possible simple remedy for this problem:
1. Turn off phone.
2. Remove SIM.
3. Turn on phone.
4. Wait until phone fully boots. (my phone did not detect SIM card and had emergency mode available, showed normal information in About Phone options)
5. Turn off phone.
6. Re-insert SIM.
7. Turn on phone.

PS : It seem since the serie KI* there's a lot of similar problems (i saw many thread during my research this morning about this kind of trouble)
If u flash different carrier branded firmware in CSC & do not set it correctly,
u may find that u can't see ur IMEI via *#06#.
Don't worry. It is still there. This is my way to solve it.
(just several seconds and without efs backup)
1.edit carrier branded code in "/efs/imei/mps_code.dat" to meet what you flash.
Ex. My S2 is CWT in the beginning, so I flash a CWT CSC and edit the code to CWT
2.use *#06# to ensure if IMEI could be shown correctly
3.To double check, u can use *#272*imei#. If u can reset carrier branded code then it is done.

You could try flashing stock rom, heard that this sometimes restores imei, not sure if it works on s3
Also, check if the rom or kernel you flashed created a eggs backup, some do

Did you back up the efs folder before you flash your device?
I understood that imei numbers were hardwired into the phone. And changing them n having the equipment was illegal. This is what the networks use to bar your phone if it gets stolen.

How to restore your IMEI number on SGS3 (GT-i9300)
I deleted my IMEI number when flashing roms a few days ago and it was showing as 000000...
I searched everywhere for a recipe of how to restore it and could not find one that would work. The closest that I got was a brilliant post (see link below) describing how to restore the IMEI on a SGS2 i9100. After following this recipe, I was able to restore my IMEI number to 0049 .... which is just as useless as 0000....
It took me a couple of days of research (and HUGE thanks to everybody whose previous research I was able to use) and I finally succeeded in restoring my IMEI using the 9 step process that I describe below. I can't guarantee that it will work and I do not know if it will work on any device besides the SGS3 GT-i9300 (international SGS3), because this is the only device that I have and was able to test the process on.

Restore IMEI on SGS2: http://forum.xda-developers.com/showthread.php?t=1264021
Download EFS PRO: http://forum.xda-developers.com/showthread.php?t=1308546
Download your original firmware using check fus downloader (http://forum.xda-developers.com/showthread.php?t=1032437&page=18)
You need:
-EFS PRO, a brilliant little program for Windows used to backup / restore the efs folder as well as recover / repair the nv_data*.bin files.
-Windows
-Windows USB drivers
-Rooted SGS3
-Root explorer.apk
-Original phone firmware (actually, you only need the modem.bin file, so once you download your firmware package, you can just extract the modem.bin file).
-Odin or Heimdall
Your phone's IMEI number is stored in the ".nv_data" file in the original shipped efs folder.
Process:
1. make a copy of your EFS folder using root explorer and store it somewhere safe (on your SD card and external SD card should do it).
2. delete the EFS folder from the root of your phone using root explorer.
3. reboot the phone
4. open root explorer and go to the EFS folder (yes, it is still there! The Android OS has generated a new one for us) and delete the following files:
nv_data.bin
nv_data.bin.md5
nv.log
.nv_data.bak
.nv_data.bak.md5
nv_data.bin.bak
and the entire IMEI folder.5.Now go to your backed up EFS folder on your sd card and copy the IMEI folder and the " .nv_data" file (note the dot) to your new EFS folder.
6.Make another copy of the ".nv_data" file in your new EFS folder. Rename one of them to "nv_data.bin" and the other one to "nv_data.bin.bak".
7. Connect your phone to your PC and start up EFS PRO. After your phone has been detected, press the "Repair nv data" button to correct the ownership and permissions.
8. Reboot your phone into recovery mode using the three botton combo and flash the original modem firmware (the modem.bin file that you extracted earlier) to your phone using Odin (use the "phone" button for the upload) or Heimdall (use the "radio" partition for the modem.bin file upload).
9. Reboot the phone normally and your IMEI number will be restored and you will be able to connect to your mobile network again
Good luck and let me know how it goes

Hi there
You need YOUR IMEI number back (which is not 00000... or 0049...) it is the one under your battery.
If you followed all the steps, then it should have worked.
One extra thing that you can try is if you did not flash your original phone firmware (and you only flashed the original modem.bin file) then do this step first.
And then work through the 9 step process, ignoring the step where you flash your original firmware (because you will have already done it).
Good luck and let me know when it works

Hi there
Good news is that it will work - even if you did not back up your efs folder before you messed with it!
Give it a try and let me know when it is fixed.
Good luck
Procedure not work!

Hi,
after flashing a modem, i got a "fake imei", and i can't connect to my provider.
After some search i found a thread to recover:
- copy esf to sd
- format efs
- restart
- copy imei folder and nv_data.bin.bak (from 2010) to nv_data.bin
- restart
i'm still stuck with this imei.
Is there something else to do ?
i tested this process with android 4 samsung, and 2.3.5
do i have to be in the same release than first time i used the phose ? (2.3.3)
thanks for advises/help.

Try GSII_Repair.

Hello,
Thanks for your suggestion,
i tryed that yesterday, but as i have no backup how can this solve the problem ?
should i rename something ?
i did the few steps to format and reinstall. but it still the same.
I noticed after flashing the modem, the timestamp changed from 2010 to 2013 on the file nv_data.bin and .md5
i had a .nv_data.bak from 2010 is this the correct one ? (in the efs folder)
this is the one i'm trying to restore, if possible/correct ?

If you tried SGII_Repair I assume you've already tried this and didn't work, right?
If so, try going back to previous MODEM (back EFS folder with HC kTool first).

Not the original ROM, the last modem you used before flashing the one that got you in this mess.

Okay, so you've got 2 EFS folders, one in your SD card and the other one in system's folder, all same files in each folder, am I right?
the copy i have is a backup i did after the problem.
not sure at this time, i'm thinking to restart fresh, i'll copy /sdcard/efs to /efs and replace.
Then i'll try again gs2_repair to see if i missed something.
Woot working get my imei back and online
many thanks !!!!

LS6 didn't work for you?
REMEMBER to BACK UP the EFS folder!
LS8 and LS6 make my imei disparear if i use getril to have the same ril/baseband
if i use ril xxlq6 with the modem LS8, my imei come back (*#06#)
but reception is very poor
i'm using CM10.1 nightly 04022013
now i'm using xxlq6 baseband and ril; it is most of the time full strength, then sometime fall to -130 DB 0 psu
but if i start a call to my second phone, it pass from -130db to full strength
