or can i just get the file from another phone and do some editing ??
y not 1 answer to me ?
can i just get the file from another phone??

what will happen if i do by this way ?
Ofc you can try.Here are the files. http://hotfile.com/dl/120562433/d70ac90/files.zip.html
thanks ,
This file is either removed due to copyright claim or is deleted by the uploader.
i have few friend use SGS phone, i can simple get the file from them ,
the problem is i don't know when will happen if i just copy the file from other SGS phone and paste it on my phone .
the imel number will changes to my friend imel number ?
I dont think your imei changes, but your product code might change. Imei is in "imei" folder.
Ps: Hotfile sucks I uploaded files by myself....
They're the backup files and it won't cause a problem that they're deleted. They should be recreated by rebooting your phone if not, just copy the original files and rename them.
You should definitely disregard previous advice in this thread.
This is the link for the eclipse 3 mini apps (taskbar apps). I extracted the file from stock ROM (Hong Kong version).
221.133.45.238 / MiniApps.zip (remove the spaces)
1. Unzip the file.
2. Copy the file to your tab.
3. Use file manager with root access and mount '/' as writable.
4. Copy the unzipped files to /system/apps.
5. Reboot your tab.
thank you!

Hi all..
So Im pretty new at flashing androids, been using ubuntu for years and am quite familiar with the terminal as well as computers in general. I made the silly mistake of not doing a complete backup of my phone with CWM before flashing with CyanogenMod 9 and now my EFS folder is "empty" but still with Zero free space... giving the "usual" errors":
1) Corrupt or incorrect ( FAKE) IMEI number. (International Mobile Equipment Identity)
2) No Network and Signal ( calls, sms and mobile Internet not working)
3) No base Band or Unknown Baseband
4) Sim card lock missing
as described in the [A.I.O. Helpline] My Android Solutions.
CWM seems to have created a copy/paste backup of my EFS folder (not .zip and not .img, just a folder) on sdcard/efs/backup but the EFS folder is read only and root manager cant paste into it. I've read that deleting the EFS folder should recreate it, I tried in terminal with
Code:
rm -r /efs/*
and got the reply:
Code:
rm failed for /efs/lost+found, Directory not empty
How do I go about restoring the EFS folder?
Finally figured out how to copy/paste into the read only EFS folder! I have searched probably about a million threads, all say to "just copy paste" into the efs folder... but never how to do it when its locked because of read only permissions.
I think im one step closer.. but still not quite there yet.
The way to get write permissions is simply to open terminal and get root access and unmount the efs directory using:
Code:
umount /efs
After that, I could open the efs directory in Root explorer and mount it as R/W. Automatically, I get some default files there created by the system which I can delete and then I could copy/paste my backup into the efs directory. Bang, mobile network running, but baseband version is still unknown. Also, my IMEI number is the generic one, not my unique one
The problem now, is that on reboot my EFS directory goes blank again... anyone know how to continue from here?

Solution:- Reason is you had Jumped from GB to JB (should be on ICS before JB), so now you need to
1) Download Root Explorer from Play Store and use it to
2) Search you internal SD card for sdcard/backup/efs
3) Copy nv_data.bin, nv_data.bin.md5 and nv.log paste them into /efs in your Phone memory
4) Reboot to get back your original IMEI
If it gets lost after reboot
Remedies for those who have a efs backup
If you Have a Backup and you want to restore it, this is one method Here or you can use the restore function in the app that you used to back it up
If restoring the efs folder or you have a nv_data.bin backup but if you write nv_data.bin or .nv_data.bak it's being deleted on every boot, than follow this [GUIDE] how to get IMEI to stick across reboots to make it stick.
BUT try this method first
Copy Paste EFS folder with root explorer, after paste , power down phone and reboot into recovery and wipe cache before rebooting....this worked for some

Thank you, I had read each thread linking from those threads but it was good for me to do it again!
Flashing the EFS folder with Heimdall gave me the same results as copy/paste, setting the ownership/permissions made no difference in both cases, always empty on reboot.
FINALLY, these are the steps I took to get my phone "working".
1: Odin re-installed the stock I9000JVJV9_OJVJV9_JXJV6.tar file found on sammobile.com as well as the Pit file found on 4shared
2: This gave me an error on bootup... something about "failed to mount dbdata", this was solved with Odin as well by selecting only PDA and using the dbdata.rfs.tar found on hotfile.com.
After this, my phone booted up with the generic imei, a very welcomed change to the previous no imei thats been bothering me! Also, my baseband is showing, the EFS directory is full of files and google play is working... and fortunately, my carrier doesnt seem to care about the generic imei
I'm still going to get my imei back, but first things first! Its time to do some backing up!
Current plan is:
1: Install ClockworkMod
2: BACKUP
3: replace nv_data.bin with the backed up one.
4: reboot / see if my IMEI number is back.
5: BACKUP
6: install CyanogenMod
I hope this helpes someone down the road.. dont be shy on letting me know if my hours of pain helped you!
And... one more thing, my phone is Samsung Galaxy S GT-I9000
Thanks again for pointing me to the right direction
did you only used the PDA included on the I9000JVJV9_OJVJV9_JXJV6.tar file? and how did you use teh dbdata.rfs.tar? thanks.
efs Folder Contents
Hi Guys,
I am hoping you can help me with a problem.
I have a brand new GalaxyS2 i9100, which is on ICS 4.0.4 IMM76XWLPW - XXLQ6 Baseband version, Kernel 3.0.15-1056084 [email protected]#3(SMP PREEMPT Wed Aug 22 2:55:24 KST 2012). The phone is not rooted, but what I did was make a copy of my efs folder to my PC, obviously incorrectly, using My Phone Explorer.
I thought it was just a matter of uploading the folder to my PC and it could be used in an emergency, I thought it would just copy the folder.
What I have discovered, is that all the contents of the efs folder are now on my PC and the efs folder in my phone is empty!!!!
I am now unable to get the files, back into my phones storage.
When I enter *#06# into my phone, the IMEI number shows up and is correct.
I also have a copy of the original efs folder, on my External SD Card.
I have not changed anything else on the phone, other than removing the efs folder contents to my PC. Is there a way, to get all the contents back into my phones efs folder without having to "Root," using say....Emulator or something?
Would a "Hard Reset" on this unrooted stock phone, restore the efs folder to factory settings??
Thank You.

I would be careful with that, if you have your efs folder on your sd card, I think it would be better to copy/paste them with root explorer back before reboot... though this is just a guess. In any case, since you have the folder on your PC, then at least you have the backup you need if you get into serious trouble.
If it did reset, please tell us about it in case someone else needs this info later
efs file restore
Thank you so much. After days of not having calling and texting functions available from a corrupted efs folder, who would have thought that a simple copy and paste of the backed up efs to the system would help greatly?
Hey, this worked for me, but I still can't connect to some carriers.
I have a i9070 and I'm trying to backup my EFS folder, but I can't find all the important files like nv_data.bak in there.
I have rooted my phone and installed Root Browser. I browse to my EFS folder, I copy it and paste it somewhere else. I've checked the option to show hidden files both in the cell phone and in my computer, but when I browse either that folder or its copy I only get these contents:
/bluetooth
cryptprop_lock_pattern_tactile_feedback_enabled
cryptprop_lockscreen.password_type
cryptprop_persist.sys.timezone
/dmp
GUARDFIL
nv.log
/wifi
cryptprop_applied_result
cryptprop_lock_pattern_visible_pattern
cryptprop_lockscreen.patterneverchosen cryptprop_rebootMode
essiv
/imei
/RFHAL
cryptprop_lock_pattern_autolock
cryptprop_lockscreen.lockoutattemptdeadline
cryptprop_onetimeboot
cryptprop_securewipedata
/FactoryApp
nv_data.bin.md5
/RFHAL.DEF
Note that there's this file called "nv_data.bin.md5", but it's empty.
Any clues about why the "super important files to back up" are missing and how can I make sure that I have a copy of them?
I know that a lot has been asked and answered about EFS in this forum and I've searched for this specific issue, but I couldn't find anything that would help me.
Thanks!

You do not backup it like that, need to backup partition. Look, there was some guide in CM10.1 thread from Frapeti I think.
