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.

Hi all,
I recently upgraded to JPM version of froyo, and wanted to change back the product code to the original. After restoring from the .bak files, I got back the original product codes. However, while copying to another location for backup, I deleted the contents of the /efs folder by mistake (atleast I think I did).
The /efs folder is empty, but the phone still works fine. Haven't rebooted the phone for fear of bricking it. Is there a way to recover deleted files? Or are those files just hidden from view?
Someone please help
Update:
Managed to get of copy of nv_data.bin from a folder used by sgstoolbox. Rebooted the phone and phone works fine. Checked the folder contents, has nv_data.bin, nv_data.bin.md5, .nv_state and a folder named .android. Is there anything else which should be there? How to restore?
Do you have a backup of your /efs folder?
Woah same happened to me just some Hours ago !
If you used SGS Toolbox to check, you are lucky because it automatically creates a backup.
-> I think SUFBS Explorer deleted the efs because i am sure i checked "copy" ... anyway !
If you have any backup file, you are lucky.
One question by the way:
I´ve also lost the "IMEI" Folder, but my IMEI is still correct. Is that because ne nv_bin is just enough for the system checks ?
EDIT: Go and check with SGS Toolbox, if it displays your code, it is still there + it creates a backup file on your sdcard (you should double-check that anyway)
I'd say that the best and easiest way of restoring your product code is by using this: http://forum.xda-developers.com/showthread.php?t=787163
messing around with /efs folder is not a good idea, especially if you don't have a back up.
Just remembered that I have a titanium batch backup of system + apps taken a while ago when I was on stock firmware. Any way to restore the /efs folder from that? The shock of losing the /efs folder was enough to jolt me out of a beer induced haze ;-)
The phone still works, which is good news. But anyway to restore from Titanium backup?

Titanium does not backup /efs.. If you don't have a backup, you're basically screwed! Sorry to be the bearer of bad news
Like I said, the phone works fine after I restored the nv_data.bin file. I listed the files which were rebuilt by the system. Is there anything else missing? Can someone post a screen shot of the contents of your efs folder?

Oh, so you DID have a backup? Nice! Besides what you lited in the first post, there are the following things:
.imei (file)
imei (folder)
- .nvmac.info
- bt.txt
- mps_code.dat
Any idea what those files are for? Possible to check what they contain?

Like i said, my imei folder was deleted aswell...
No problems so far with that !
Use rootexplorer, dont use ASTRO. It's crap and does not show all files, including the whole /efs
My EFS folder is empty too...and I don't know why, I have only flashed a couple of time with odin and JM9....
But SGS Toolbox report my csc correctly as ITV....even if I used the HUI csc from my operator with odin....
Could it be a problem if the efs folder is empty? The phone is working well...the only problem is that it loses very often the wifi connection...but I don't think that it is csc related...
Hi!
I downgraded from ICS 4.0.4 IMM76K to 2.3.6 GB.

The same sim is detected in all other phones. No other sim is detected in my gt i9000!
Plz hlp me with the easiest way cuz im a noob!! i've tried the "9 steps to recovering IMEI" but i get stuck at the terminal app!! its not working for me! :-((
I have the eps backup file on my sd card, i copied it to my root phone dir but it still didnt solve the problem!! I tried EfsPro as well, didnt work for me! Im a noob so i may be missing something. PLZ HELP ME PPL!! :-((
I'll highly appreciate your help ppl!!
Thanks
Where did you copy your Backup
Sent from my GT-I9100 using Tapatalk 2
I made a backup via cwm..im trying to restore "data" and "system" via advanced restore and see wether it works..currently doing that
OK let me know then!
If it not works, try the app nitrality from market, you can try to restore your efs backup with the app
Sent from my GT-I9100 using Tapatalk 2
didnt work.
So now I am fully restoring it via CWM, before i was rebooting into CWM mode, and then advance restoring.
Ok I'm gonna also try that app and let you know!
Btw thank you so much for your help man!! Im so bloody depressed! :-(
The damage is reversible right? I mean im not a gonner am I? I'll keep you updated!
Since you made an backup of your efs folder its always possible to restore so no reason for getting depressed mate!
Sent from my GT-I9100 using Tapatalk 2
I restored it fully, but after the phone rebooted, it just got stuck at the boot screen..i took out the battery after 5 mins as it was still stuck at the boot screen.
What do you suggest now? I'll try that app you suggested once I get my firmware working!
Retiring for bed, will follow up on your advice when i wake up..
Go into the recovery and make a factory reset, if the Akku trick won't work

Did you make sure you flashed with a .pit file as well,? You must do this down grading as the file partitions are different from ics
Ok I tried to go into recovery mode, but the phone would just boot again, from the very first boot screen (where samsung is displayed at the bottom)..so should i flash again with the .pit thingy?
ok guyz nitrality didnt work..flashed it with gingerbread with .pit again..no imei number

Do you have a back up of your efs folder?
Yes i have the efs backup on my pc and ds car. I tried copying the efs to system root dir, but no luck.
the nv_data.bin file is 2MB in the backup folder on my sd card, but as soon as I copy the whole efs folder to root dir, this nv_data.bin file is 0bytes size..
One question, when u copied your Backup into the root directory
Did you made a reboot then?

he restores IMEI.. may be he can help you.
He can do this when you can show and prove that you have and own the original imei number. He can't "invent" one.
So you should check this first.

No, because using hardware equipment is part of the repair process.
Until now I do not know a "software" restore mechanism (if you do not have a working backup of your old efs).
And I read and checked a lot of threads about this because I have a device where the IMEI is written in letters inside the device but not anymore in the efs - I have the so-called developer IMEI.
You should fist explore your note with root explorer. Depending on the rom you're using, you may have a backup of your efs partition (some rom do it automaticaly).
Watch your SD card if ther is a file called "efs.img"
You can also look inside the efs partition if there are files called .nv_data.bak and another one called .nv_data.bak.md5
If yes, you can fix it yourself.

Pssst, do not tell anybody. But I guess that developer door is closed now, since November nothing (I check for OTA updates every day - I can do the install XXLSA/restore GB backup process while deep sleeping now).
i have found in the efs folder from internal memory the files! what now?

well you are stubborn, stubborness is annoying but can lead to great inventions and progress. However to save you time shiuld you fail, you will not without an efs backup be able to fix this. Imei gone is gone, no efs backup then need Samsung or cvxcvx.

All can be done with root explorer. Just long press the file to rename and then chose "rename" and edit the name.
Files don't have to be moved, everithing needed is inside the efs folder.
After renaming those files, just reboot the phone.
so i delete the efs folder from internal memory and i did what you said to me and nothing take a look at the pictures

Hello
I have a Samsung Galaxy S with SlimBean Installed, previously I had the stock 2.3.3 XEF version and CM9
When I rooted the device for first time the first thing I did ws backing up the EFS partition, I have made subsequent backups since then. However, the files don't seem to be equal and don't match the .MD5 signatures provided.
Do the files in this partition change over time? Does that mean they are getting corrupted? The most logical thing would be that the signatures matched the files but they don't..
Thank you.
Hello
Any ideas of why this happens and if it's normal?
Thank you.
And I've just checked my phone, the .bak files have dissapeared.
I've got an old backup tho, but why did they dissapeared?
Thanks.
Edit: The rest of the files are in the efs folder, they weren't displayed because Slim filemanager doesn't show hidden files by default.
So the only question remaining is: Do you know why the MD5 signatures don't match the files?
Thank you.
I think since IMEI is unchanged - thats ok. The most important file you have to keep is nv_data.bin (i think that one) it holds your IMEI. So as long as your phone works - no panic.

Hello
Thanks. But why does the hash change and differs from it's MD5 signature?
Probably so.. dont worry about it and keep nv_data.bin just in case.
