[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.

I need some help. EFS empty folder and no backup

Hi, Im Penny and Im from venezuela.
I just got an Galaxy Note, a friend gave it to me, but the problem is it cant accept SIM card.
I have read a lots of guides and stuff, but neither my friend or I have any efs files backup.
In settings there is no Bandbase (unknow), Android version is 2.3.5 and kernel is 2.6.35.7-N7000XXKJ4-CL641703 [email protected] #2
So, i read something about rooting and stuff, I already did, but there IS NO FILES in efs folder. And there is no IMEI neither
when i do *#06#
I tried putting a stock rom, but there still the problem there. I read in a forum a guy that someone gave him some
Galaxy Note efs files, he restore them and it works. So i really dont know what to do.
Can some give me some help and give me efs files and see if I can repair this? I really need this because im planning to selling this (because i need the money).
Thank you and sorry for my pretty bad english.
** Edit: TO THE MODS:
Note: If this post breaches any rules, please remove (I'm learning bout this)

I am having the same problem. If anyone have the /efs files, please send to me as well.
** I am able to use the hex editor, only will change it back to my original IMEI, not going to use other people IMEI.
TO THE MODS:
Note: If this post breaches any rules, please remove my post as well. tq..

No one in the right mind is going to upload their efs folder containing their imei and serials and addresses
It is possible to change imei but I suggest you don't do it as it is highly illegal and carries a prison sentence, but if you try then start with a hex editor and look inside the nv_data.bin - if you can edit it only edit it to your original imei or that's where you run the risk of being bummed by some big steroid infested guy in the showers.

Exactly what azzledazzle said.. Read that post thoroughly, the one he linked and try if it works for you. The EFS folder contains highly sensitive data, the very reason I couldn't send you the file! Hope you get it..
Try if it works for you..

[Q] Missing /efs folder yet phone works

Hi All,
like many of the users I have a problem with missing /efs folder. Although I can't find it I have my IMEI and my phone (S5830) works fine. I can make and receive calls.
But let's start from the beginning. I had Android in 2.3.3 version.
Using this post http://forum.xda-developers.com/showthread.php?t=1034145 I have upgraded it to 2.3.6.
I have also rooted it using universal_gb_root_v25.zip.
Now I wanted to play with it a little more so I though of doing backup. Previously I made one using CWM but I read that it doesn't backup /efs folder that stores IMEI and other important data. So I started searching through the forum for a solution. I've downloaded EFS Professional but for some reason it gives me error "An error occured while getting partition list!" when I select my phone from the drop-down list on the backup tab. I cannot do backup because the "Device Partitions" window is empty.
I did not give up and searched the forum a little more. So I've downloaded two apps: ES File Explorer and Root Explorer. Unfortunately both could not locate /efs folder. All the Linux folders were there except /efs. There's dev and next is etc. No efs.
So I though that maybe the folder was hidden but the I checked the options of Root Explorer to show hidden files.
Lastly I checked the method with adb shell and busybox like below:
adb shell
su
tar zcvf /sdcard/efs-backup.tar.gz /efs
but as I though I got the message that /efs folder could not be found.
Has anyone have an idea how to get to /efs folder in my case? Where does my phone keep IMEI? How to backup (and restore) my phone in this scenario? Is there any other way to backup the most important files?
I know there are lot of questions but I'd appreciate helping me with it. Thanks in advance.

its difficult to find the efs folder bt u can check ur IMEI number by this code *#06#.
you can backup efs files by efs professional tool.
a CWM backup is also safe as it includes most of important files.
hit thanx if helped.

Thanks for the one above. From this post I read that SGA does not have /efs (folder/partition) or it is not mounted by default so I can't see it. Which one is the right answer? It does not exists or it is not mounted?
If doesn't exists then where should I look for IMEI data and all other critical stuff?
If it exists I could issue:
mount -r -t ext4 /dev/block/mmcblk0p3 /efs
-r not to make any changes. I would have to create /efs folder first using: adb shell mkdir /efs
Am I following the right path?
I'd have already tried that but don't want to screw up my phone. Thanks in advance for any suggestions.

Thanks for the suggestion however this doesn't bring any useful information to this topic. I already know to be very careful with EFS data.
I would like to get some answers about configuration of this data on SGA. I would like to know whether there is a way to back it up That's all

I think it's useful...anyway It's really simple, FORGET TO BACKUP YOUR EFS FOLDER OR YOU'LL BRICK YOUR PHONE!!

First... the question is why would you wanna backup your IMEI ? You needn't even write it down as a backup if you have the bill of your phone. And in case if you ever lost the IMEI, there is a guide to restore it & you can restore your older IMEI. So why worry to backup ?
Sent from my GT-S5830 using xda premium

I wrote the IMEI down just as a precaution. I didn't know it was on the bill as to be honest the phone used to belong to my wife. I know there are several threads about restoring IMEI and other necessary data. I have already viewed them.
The reason I put this thread was that I was unable to locate the famous efs folder. I'm new in this stuff but I'm also a quick learner. After going through several threads and articles I was curious why I could not locate efs folder on my SGA. Answers such as "don't look for it or you will damage your phone" are just simply not what I was looking for. Anyway if someone please explain me the technical details of this phone and the reason why I can't make a backup using several tools and methods I would be very grateful.

Your quest for the efs folder is unending. I appreciate your effort in learning new things but what's the point of finding something that's of no practical use ? Yeah, you can't find the efs folder & no one else has ever worried about it coz everyone knows how to get their phone back online when they lose their IMEI. So either backing it up or looking for it is not worth a penny . All that counts is that the phone works & that the IMEI is secured, be it without that folder of your interest. If you clearly state your intentions with what you have to do by backing it up, someone might be able to help.

Hi I am have just joined the forum searching for a help. It was my first time flashing custom roms and had been at fault in technically missing some of the instruction. I have failed to backup any bin, img or efs folder which could help me fix IMEI. using MTK droid tool (for MT6589), I am receiving an error of missing pttycmd1 and even searching the root of my phone, I can't find any nv_ram or efs. Is there any other way to fix my device?
Baseband: Unknown
No IMEI
cannot use AT+egmr command
thanks for the reply.

efs ?
efs is a partition for sim unlock right ?

i do hope so, because I just read from other threads about exploring and backup of efs can fix baseband & imei.

I can't find my efs either. The issue I'm having is to get rid of Factory Mode. Have seen tutorials on how to do it, but the efs file is missing and so I can't actually do it. Any suggestions on how to fix these issues? Thanks

[Q] i8190 IMEI NULL/NULL

Hello,
got the same Problem like alot others. Wrong flashing and the complete EFS was destroyed.
Now i go back to Stock, rebuild the Baseband and the Counter is 0. But still have IMEI NULL/NULL
I read now alot of posts in the Net and tryed a lot but nothing helped.
So my Question is, is there really a solution to build the IMEI back to the Original one if you completly lose the original
EFS Folder? Or do i need to get it to technican to get it back with a Box?
I tryed IMEI Changer App but this one doesnt work on my i8190.
If there is another way to fix this, would be grate to get a but of Help.
Thank you in advance.

So i try to change the IMEI with ALP. But ALP directly gets an Read Error while try to get the IMEI.
Is there a File i can put in and change it with ALP to get back my IMEI?

I had the same problem when i was on my SGY. Just reflash the rom through odin and fix permissions. ??
There is no bad choises, only bad results.
SGS III Mini
tenshi_xp's PAC Rom RC-3
KitKat 4.4.4.

Hi,
thank you for your Answer. But i already reflashed Stock Rom all things are back, i just miss the IMEI File or Area. Saw on the net there are IMEI Folder to flash with ODIN
so i can change it with ALP. But most of the Sites or Files or deleted, maybe false and Viruses, i dont know.
My Problem is that my complete EFS Folder was lost, no Backup nothing. With different Flashes and Stuff i got it back with Baseband, CSC and so on. Just my IMEI tells
me NULL/NULL and ALP cant get it, because this Part isnt available anymore
Can you tell me Stockrom or something i can try? Need something for an open German i8190.
Best Regards

Our IMEI number isn't saved in /efs partition/folder. It's saved in mmcblk0p9 partition which take up to 1MB. The efs partition (/efs>imei folder) only contains the IMEI key code to access the IMEI number in mmcblk0p9 path. If your IMEI key code got wiped and you didn't make a backup of your efs partition, then you will (unfortunately) never see your IMEI again
BTW : Does WiFi, Bluetooth etc. works or not?
EDIT : I found a interesting therad for you http://forum.xda-developers.com/showthread.php?t=2755787. Maybe you can use this efs backup from this user and change the IMEI to your original one.

Yes all other Services are working WiFi and BT. Just the IMEI Numbers are gone.
But if its possible to recreate the Folder and File i think its possible to change the IMEI Number with APS to the old one from the Mobilphone.
But i can get them back if i recover with a OctupsBox or how this boxes are calling?!

There is an alternative method. You can flash this efs.img (which you find in the zip file) with terminal emulator which needs ROOT access.
1. root your device and download terminal emulator from Google play store.
2. Copy the efs.img to your internal storage and open terminal emulator.
3. After open terminal emulator type su to give root access, (your supperuser app asks for root access, confirm with yes)
4. Type/Copy this code : dd if=/storage/sdcard0/efs.img of=/dev/block/mmcblk0p11 in terminal emulator and press "enter"
5. Now your efs partition got overwritten with the efs.img
BEFORE!! you start this method, backup your "current" efs folder by type in terminal emulator : dd if=/dev/block/mmcblk0p11 of=/extSdCard/EFS.img
Please do this at your own risk!

Temporary Root on 6055K

The main reason of this thread, is that I has got a problem with the SO. I followed the rooting guide of DeckerSU, and when I tried to delete/update an app on System, Link2SD, Solid Explorer, and Titanium Backup said me something moreless than "mount: read only filesystem". So, please, help me to fix it (because I don't think that be with the reason of do and restore an TWRP backup to gain my RW system).
PD: Please don't post information, or answers about to do a script and put it on init.d and say it that always I boot should mount it, because I tried EVERY thing that I found on Internet (That I found, if you find anything, please post it, to help me, and to people who want to fix this issue)
PD2: Sorry about my poor english, that's the best english of a teenager of Spain that you'll see
