[Q] FIX Device ID: How?

Thanks to the good folks here i've just upgraded my Galaxy S to the leaked JPM firmware. So far so good - much faster than JPK I was on.
However - I'm having problems with the Appbrain Fast Web Installer and seem to have found out that it's due to the android device ID being the same because we're all using the same ROM (or something) (http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=798644)
So.... How can I find out what my Device ID was/should be and how can I then change it to be "correct".
Any help much appreciated. Seems it might be a common issue....

Have you tried checking whether your IMEI changed after flashing? Type *#06# and if your IMEI starts with 0049... (I think...) then you need to do what almost everyone has been doing since JPC ... follow the instructions from here or some other threads from around here.
If your IMEI is fine, then I have no idea...

Thanks for info - checked my IMEI and it seems to be fine - i.e. the one i registered with my insurance with (starts 3547)
I've read the thread you linked to trying to figure out what's what but I can't see anywhere how to find out what my product code is/was/should be or how I can change it. I've seen stuff about backing stuff up (nv_data?) but I'm not aware of having changed these.
All I've done to my phone - flashed JMX and now JPM and applied SuperOneClickv1.4-ShortFuse root. Will that have changed my product code?
I'm a bit lost with this one.

Use sgs toolbox to see the crc code.
Sometimes you got the right code in the backup file.
Just do a backup of all file on a safe place. The remove the 2 original file. Restart.
You need to be rooted for this.

A bit of info that might help(?):
I loaded up SGS toolbox and pressed ""check product code" it says:
---------------------
Got root access
Copied nv_data files...
nv_data.bin could not be read!
No backup .nv_data.bak found!
-----------------------------------------
I'm guessing that's bad news?!
Under Firmware Info it says:
------------------------------
PDA: I9000XXJPM
PHONE: I9000XXJPM
CSC: I9000OXAJPM
Build Info: 2010. 10
--------------------------------------
When I tap CSC selection it says: "USSD code running" and then "UNKNOWN APPLICATION"
When you say to backup 2 original files - i'm guessing it looks like I don't have those. Is there another way I can check or is it definite from the above. If I don't have the original files am I stuck? Can I get them from anywhere else? Are they default to a phone by region or carrier (my phone is from O2 in the UK and is the 8gb version)
If you say delete the original files (which aren't there it seems) - am I right in thinking this will them make the phone auto-generate new ones? (I really have no idea what these files are for or what they do).
What's the next thing to try? Can I get hold of the missing files from somewhere? Do I even need them? And how do I restore the Product ID (if it's changed!)?
Thanks

Have you checked the path manually for them?
If they are not there you are in deep water.
Its you personal data for the phone and you can't use others file.
Search this forum for help about this.
I can only give you a advice what i would do if i had that problem.
I would flash a original firmware that is lower than its on kies.
Then i would upgrade thought kies.
Then i would check if the crc code is there and right.
If it still wrong then i guess i would make the phone look like it was out of the box and return it.
If the code is right i would make a backup(full) and on this files( to my external sdcard).
Then i would upgrade to jpm/jp6.

Hi - thanks for reply
I've checked the /efs folder with Root Explorer and it seems i've got:
.android - folder
.nv2.bak
.nv2.bak.md5
.nv_data.bak
.nv_data.bak.md5
.nv_state
/imei - folder
nv_data.bin
nv_data.bin.md5
Now i'm guessing this is good? is it all in the right folder?
Just to clarify - I've never messed with this folder - I've only ever flashed with Kies and cleared the cache and restored factory settings with recovery. I've also formatted internal and external memory card.
So are these files my original files? How can I tell? Are these included with the Rom's I've flashed? (JPK and now JPM)
I've copied the entire efs folder to a safe place - is there anything else I should backup also incase I can't restore it?
SGS toolbox still says:
---------------------
Got root access
Copied nv_data files...
nv_data.bin could not be read!
No backup .nv_data.bak found!
-----------------------------------------
Why can't SGS toolbox read the files?
Many Thanks

Maybe I am not following this thread correctly, but your last post deals with IMEI and unlock data. Your first post said you needed to change your deviceID. You even link to the Captivate thread that discusses the problem AND in that captivate thread is a link to change Device ID - http://forum.xda-developers.com/showpost.php?p=8604909&postcount=3550
review that post as it tells you where your device ID is located (it is not in the nv_data.bin file). Also, in the captivate thread, one person said he just made one up and that worked for him.
If you mess up with nv_data.bin you will mess up your IMEI and any unlock the phone has - so I caution you be careful.

I made a thread with the solution
http://forum.xda-developers.com/showthread.php?t=815503
This should work.

[Q] (i9000)Deleted efs folder without backup!! Possible to restore?

Unlike other cases posted previously...
All files in efs were deleted, including all hidden .bak files
Now, kies displayed my phone have a product code of XXXXXXXXX and a fake IMEI...
Is it possible to restore the nv_data.bin and other files??
Please help! Thanks....

I have the same problem, is there a solution for that?? Please answer!

Did you install sgs toolbox and used it's check product code function before you deleted your efs? If yes, there is still a chance. If no, there are currently no public fix available yet.

We are on the same boat, as what francis posted. No public fix yet but pretty sure there will be.. its just a matter of time.

the same thing happened to me yesterday when i flashed Cyanogenmod 7, got fake imei but everything worked just fine (call, data, market).
today i deleted everything from efs folder using Root Explorer then installed i9000XWJS5 then, surprise, i got my original imei back.
do not know how and do not know if it will work on you but it worth a try

The same thing happened to me.
If I dial *#06# no imei appears.
In order to use the phone everytime I boot up I have to give r/w permission to system folder. Otherwise it doesn't recognize the sim card.
It seems to me that that the device is not anymore able to recognize itself.
If I try to install CM or other AOSP rom I have status 7 error.
In Rom manager I have a window where I should select wich kind of device it is.
In fastweb installer there is a list of devices and I have to choose wich of them I am using.
I know that there is nothing to do with warranty. But is it possible to go back to a stage where it is possible to install AOSP rom?
Thanks

don't know it may work or not, but some custom roms make a backup of the efs folder on sdcard under /sdcard/backup/efs or /sdcard/backup/efs-XXX
(XXX= some numbers). you can try to restore it from there.
again don't know for sure...

I have checked, but there is no backup.
I know the only one to blame it's me.
Do you think that there is anyway to make possible installing AOSP rom?

restore nv-data.bin

So. my IMEI is jacked up. I made a copy of /efs when I got the phone but instead of making an archive I did a straight copy, Seems like the fat filesystem owned the permissions.
I am trying to restore from that backup but I am not having luck. People say you can just drop those files into place but it seems that they are replaced after every reboot. What do the permissions need to be? I see that ownership needs to be 1001:1001. Also, can I do this on JH7 with any success?

If your flashed back to stock OTA JH7? Shouldn't need to have to restore them.
Only need to input that (if Android ID doesn't work) - you should be able to copy it using ADB shell and SU.
cp /dir/foo /dir/newfoo

I used the CWM flashable zip to get back to JH7, didn't use odin (im not at home yet, and this was eating away at me at work, heh).
Ill flash back with odin and then see where that gets me. For my own sanitys sake, could you tell me what the permissions are on your files in /efs?

i have a fix that worked for me posted in the dev section

once in jf6 if your imei isn't corrected then delete everything but the nv_data.bin and .nv_data.bak.md5.
use android terminal emulator to execute following (must have busybox installed)
su
busybox chown 1001:1001 /efs/nv_data.bin
reboot

fyi android id is different than the device id. Device ID = IMEI.

I see my problem, the efs directory I have is from my OLD captivate. Arrrg....I have no backup of my current /efs. The random nv_data.bin it creates has the correct product code already.
There must be something in the phone that knows the imei as this is why it was not accepting my dropped in files (the files from my old phone).
Ah well...ill use it till ATT blocks the test IMEI "lose" mine and go get a refurb as I have insurance.
FYI, the stock original firmware does not create those .bak files from what I could see. I bet your files had jacked product IDs but perhaps the part that went with your IMEI was still intact. This would be why my phone wont accept my old phones nv_data.bin?

once your in stock
run the terminal emu commands you should have baks once your system reboots.
I can delete my baks
run the term commands reboot and they will generate again.
if you have both bin.md5 and bak.md5 delete the bin and run terminal commands.

None of those files get generated for me or exist. If I remove everything, a generic nv_data.bin and .imei get created. Thats it. If I copy over the files from my old captivate, I believe they do get created but since the IMEI in that file does not match whatever is being checked in the phone, new files are created anyways.
I suppose nobody as of now knows how to generate the string that is in the nv_data.bin based on an IMEI so it seems that I am out of luck.
Perhaps some shady place in town can help me repair the IMEI or something

I ended up calling Samsung today. I described the problem (damaged IMEI) and they sent me a pre-paid shipping label to send it off to Plano TX to have them take a look (i'm in Austin).
I will let you guys know how this turns out.

My phone is on its way back to me. They ended up swapping the mainboard under warranty.
I suppose if you have a damaged IMEI and can deal with using an old phone for a week, consider sending it over to samsung.

did you have to pay for new mainboard? cause i got the same problem but i am not the orginal owner for the phone.

Jeez, that's wild. What is the correct way to go about backing up the necessary information while the phone is still stock? Planning on rooting (but not unlocking) my gf's Captivate and want to make sure I leave a proper trail of breadcrumbs.

It was no cost. They could see based on the IMEI that it was still in warranty. My mistake is I forgot to make a backup of /efs. If you make a backup before doing the OTA update, the unlock code in in clear text

So just back up that efs folder and that's it? Anything else?
This phone was purchased used on Craigslist so I don't there's any warranty remaining. It's a 1007 so it's older...

Well, the warranty period is a year and so since its been less than a year since the captivates release, you should be good. It would seem the only way it would be out of warranty would be if samsung for some reason deemed it to be at some point. Im sure you could call samsung with the IMEI and verify.
In my case, my product ID had become damaged. My problem is although I had a backup of /efs, it was for my first captivate, not my current. I deleted /efs and moved the backup into place. Seeing that it was the nv_data.bin for some other phone with another IMEI (the IMEI is encrypted inside that file) it instead replaced the files with a generic set of files and the dreaded test IMEI.
Since nobody had a good way to write the IMEI to that file as it expects, I was SOL.
If I could do it again, I would make a .99 cent jig (I did this using a wonderful thread here labeled something like "make a jig without cutting up USB cable) which gets you into download mode if odin or something soft bricks your phone, root, make a backup of /efs and then take a nandroid backup. I THINK I remember reading that sgstools can backup /efs for you but in the sticky there is a method on how to make a .tar of /efs (good as this will retain permissions/ownership as if you straight copy them to the sd card with fat32, the filesystem does not understand linux permissions and blows them away).

Master-Clear did the trick 4 me
OP I had the same exact same problem here. I spent many hours looking for a fix, N/G, nothing I tried would work. Didn't want to go to AT&T so I took a big chance and went into the efs folder and started deleting files one at a time. When I was through the efs was empty, did this with Root Explorer. When I did a reboot I wound up with a different IMEI, had NO data connection, NO APN, but wifi worked fine. I then did a factory reset from CW which did nothing, still no data connection. More time down so I loaded up ODIN3 One-Click and did a Master Clear. This was the last thing I was going to try before a trip to your friendly AT&T store. Well low and behold after the Master Clear and a reboot everything is back to normal! My IMEI is correct, APN is back, 3G working, wifi working. TITS! What a rush!

i9000m insanity (semi-brick issue)

Hi guys,
Ok, so I've been Googling like a mofo for the past 3-4 days, trying this and that, investigating my issues, and I still need some help.
I've got a Bell I9000M that I would describe as the following:
1) Boots into any rom I flash via Odin (so far just GB and Froyo)
2) Internal SD works (I can see my files via USB), but "Internal Storage" shows unavailable.
3)I also flashed this phone before backing up my EFS folder so my unlock number is scrambled. I have a backup of the post unlocking-attempt EFS folder, but am unable to copy this back to where it needs to be. I've tried with ADB and no dice and I've tried copying it in with the phone on using Root Explorer - Root Explorer will copy the files back (and I'll even get the no SIM icon after a few minutes), but everything's gone and the EFS folder is empty when I reboot.
I'm kinda stuck. I just got this phone off CL last week thinking I'd flash it and go on my merry way like I normally do. I wasn't aware of the I9000M's horrid reliability. Anyway, any help would be appreciated!

use the solutions on Quick fixes and solutions link below, especially the guide on how to make efs stick after reboots

Ok, so I did the making the IMEI/efs stick and it seems to have rectified everything for me! IMEI is back to what it should be, baseband is back, storage reads properly. Wow! I'm ecstatic right now! I've been dicking with this thing since last Friday and you've got me sorted in under 10 minutes, brilliant!
If you ever pass through British Columbia, let me know! I'll buy you a beer or something

HELP - CM10 upgrade and lost IMEI

Need some help here, hopefully without having to go back to JF6 (that is a little scary at this point). Was pretty happy with CM9 and updated through most nightlies. Just today I upgraded to CM10. All seemed to be working well except that I received a warning of invalid IMEI. I pushed through it and had the phone working on CM10 (with low memory /data isses - that could later be rectfied) then realized that the IMEI issue would mean AT&T would likely shut my phone down. The invalid IMEI is generic and has been flagged as invalid. I also ran into a few issues where I could not download from the Play Market App and think this was the reason.
I nandroid backed up CM10 and restored CM9 but still no dice. As I learned later it doesn't touch the efs folder which somehow the CM10 upgrade modified or had the effect to change it. Uuughh. many others were having the issue.
Anyway, I have verified that there are no /efs backups anywhere on my phone or SC or emmc cards. There are no backups within the efs folder. So, I am hosed. Any way to edit the nv_data.bin file a la this process for either CM9 or CM10?
http://forum.xda-developers.com/showthread.php?t=881162&highlight=restore+imei
This seems to be the only way I can see that would get me back with no IMEI EFS backup. But, going back to Android 2.1 Eclair or 2.3.5 Gingerbread would be a time killer and have to go through rerouting (?), upgrading, etc.
Any thoughts or direction?

All right it was a long painful night and day. Found and downloaded Heimdall One Click .jar with UCKK4 GB. Ran it and it restored the correct IMEI. It was unrooted and stock.
Then what was previously easy became an adventure to root and and load a kernel with CWM. I must have bricked the phone 10 times havimg to redo the Heimdall to Gingerbread 2.3.5 numerous times including reloading samsung pc drivers. Eventually with Odin, I found the right sequence using Corn Kernel for UCKK4 703 injected with CWM (not 705 or 706 versions which kept failing) which allowed me to get CWM loaded onto the phone.
I still could not restore my CM9 nandroid backups as the /data restore kept failing having to redo things from scratch. So, then I copied the latest CM9 nightly .zip onto the internal SD then loaded it from the Corn-CWM restore. CM9 booted and things were better but phone nad none of the settings and things still not right. Then rebooted into CWM recovery and restored the last CM9 nandroid backup. Now things worked and everything was back to normal with the correct IMEI.
Man that was a long stressing and scary day...
Made multiple copied of EFS for the future.
Will hold off on CM10 until the /efs issue is resolved as well as the memory management is better understood (while on CM10 I immediately ran into /data out of memory problems (I know I needed to move things to SD but never got around to it once the IMEI issue came up).
So, all is back to CM9 and finally working fine

odin to stock, then you will get imei back, backup efs folder, and flash back to cm10.

I have the same problem, but i'm om Rogers and 5 days now and no problems yet. I have a backup of my efs folder can I just copy paste?

Yes just make sure you set the correct permissions on the files. BTW You won't have a problem on Rogers. Canadian providers have all their black listed (lost/stolen) imei separated. They don't share it so a black listed imei on Rogers will work on Bell or Telus and vice versa. Only thing is that your phone can no longer be tracked by imei in case of emergency since its not the correct information but E911 will still locate you via GPS if you ever place a call.

It sounds like you have the backup that is sometimes made in the /sdcard (or /mnt/sdcard) folder, which is the internal storage you see when it's connected to your machine.
To see the /efs folder (assuming it exists), you would need to use either shell commands from inside ADB, or a root file explorer. If it's not there, you should just be able to dump the contents of that backup folder to a directory called /efs and go from there.
