Me and My girlfriend both have the SGS2, mine black, hers white.
Instead of all the settings/installations I thought maybe to backup my phone with CWM and restore it on her phone.
Is it possible?
Will it work...?
Won't it ruin anything important with the phone, such as imei issues or anything?
The reason for thinking about it is that she has some unsolved issues and I dont have too much time to spend doing all the checking and installing things..I just know mine works well and it seems the easiest way
It will work as long as the back up does not have EFS in it.
EFS contains information about imei.
The backup is consisted of a several .img files.
How can I tell if it contains EFS or not, and if it does, how can I 'tell' CWM not to backup this information?
list the files in back up and we will tell which ones are safe to transfer.
Sorry, The following are the backup files:
.android_secure, boot, cache,data, nandroid.md5,system.
As far as i am aware backup does not contain EFS but i am not 100% sure .

I'm also interested in this as I would like to port my existing phone backup to another SGS2, but I have doubts re MAC address and also IMEI.
EFS info stated previously does not give much insight, but what I have as a regular CWM backup is: nandroid.md5 *giving proper checksum for other 4 files), boot.img, cache.ext4.tar, system.ext4.tar and data.ext4.tar files, totaling ~ 1.20GB. No EFS dedi files. I fear my second SGS2 might receive wrong info through backup flash, thus resulting conflicting one with another. As both phones will be used in the same household (my son would receive my old SGS2), and also IMEI is worrying me as I wouldn't want ending with both of them having the same one and resulting illegitimate while both SGS2 are legit!
I searched with google, but haven't found SGS2 related topics.
Anyone with more insight or willing to help?
TIA.
Cheers!
Edit: if none replies, I might give it a try as I already have CWM backup on both phones mounting the very same ROM.
Yeah it can be done. CWM doesn't back up efs so won't need to worry about that. It will put an exact duplicate on her phone though. All settings, contacts, messages, accounts etc will be copied across.

dude at any point of time u cant change the IMEI no its no ware related to ur rom hence dont worry
but ensure that u put the bkp file under cwm/backup folder other wise u cannot install the bkp from recovery
Thanks for the info guys. That is all I wanted to "hear" (read) and it seems not so complicated after all (thank god, not like on some other Android devices and nandroid backup). Will clone my phone to other one as soon as I have some spare time and will report back.
Edit: Just cloned my older SGS2 to a newer one, did complete restore of internal memory on newer SGS2 and everything works as a charm, just enabled it on my home wifi network and that's it. Older SGS2 just got dalvik etc wipe so it can be clean for my kid
So it is really a piece of cake and is doable.
Thanks for advices and hints whoever posted here.
Cheers.

Ok. Im getting a new Droid Eris today, before my old phone broke i did a nandroid back up through recovery. I am wondering if that nandroid back up will work with the new phone or if i have to flash a new rom and redo everything. Thanks in advanced
I don't see why it wouldn't work.

I remember a thread on AF a few months ago about this. I think you might have to change a filename or something. I'd try searching in the all things root section and see what you can find.
I think the folder name inside of the nandroid folder needs to be named according to your eris serial number or hardware number, something like that..the backup might also be proprietary to your device though.

The only reason i am asking is because i want to just restore if anything goes wrong with kaosgingerbread i have something to fall back on. As it stands im thinking of multi-booting just to have stability and speed, i dont know about the speed thing though.
New question does multi booting produce lag and speed issues?
When you do a nandroid backup for the first time on any phone, it creates a folder at
/sdcard/nandroid/H????????
where the last bit ( "H????????" ) is the device serial number. Let's suppose that your old phone has a serial number of "HXXXXXXXX", and (for instance) that you made a Nandroid backup of the old phone December 3rd, 2010 at 1517 GMT. There would be a backup folder inside that folder named
/sdcard/nandroid/HXXXXXXXX/BDS-20101203-1517
(This folder will contain four files: boot.img, system.img, data.img, and nandroid.md5)
There is nothing in that backup that is specific to the serial number of your phone, so, the easiest thing to do is to make a dummy Nandroid backup on the new phone after you have rooted it. Let's suppose that the device serial number of the new phone is HZZZZZZZZ; performing that (dummy) backup will create a new backup at
/sdcard/nandroid/HZZZZZZZZ/BDS-date_and_time_stamp
So, the only thing you need to do is move all the BDS-* folders inside
/sdcard/nandroid/HXXXXXXXX
to the new folder
/sdcard/nandroid/HZZZZZZZZ
and you are good to go.

I am not the best at looking before i post, but in my defense i needed reply fast because all that droid is doing when it gets here is it is getting its sd card and a quick call to verizon then it is on it way to be rooted. Thnak you everyone who posted and thanks to bftb0 for pointing out the fact that nothing is hooked to the serial number
I have a Samsung Galaxy S II with lost IMEI & unknown baseband, ( the source of such a problem usually is the corruptness of the efs folder or missing ), My question is if the efs folder is missing would it be possible to use another backup from another backup of the efs folder from different S2 and edit in the details needed?
You can restore from your backed up EFS folder .
Or search XDA >>> EFS will find a number of posts and some fixes .

Hi mate, I don't have a backup of the folder so can't restore
no, you can not use a efs from another phone as the imei is unique to each phone. you would end up bricking it.
You need to send it in for reflashing with specialized tools which will rebuilds your efs folder.
I have the same problem here.. any idea how to rebuild the efs folder?

Theres also a Dev called Odia that can restore lost EFS/IMEI folders.Costs i think but its worth it if you cant get it done yourself.Send him a PM.
Solution
I managed a solution to get your phone back, not perfect but works.

Cant understand why people do not make a backup of the EFS. If they all took the time to read the stickies, they would know how important this is. Learn to walk before you start to run.

That's assuming they indeed read the stickies, of course.
Reading
Read Stickies is important, but sometimes there are procedures that don't work well, or as expected, so problems like this will appear and they must have a solution.
restore with a backup folder!
You may not of personally made a backup but a lot of roms and kernels do it for you automatically, so you may have one or more backups and not even know it.
Check if you have one in /data/.siyah if you have used said kernel.
Check your sdcard for any made by roms they usually make a folder named something like efs_backup
Last I looked in addition to the backup I made 5 minutes after buying the phone I have 20+ made from each rom upgrade.
Hi, I'm new to rooting etc. Is it too late to backup an efs folder after I rooted the phone but have done nothing else?
Cool

As long as your EMS folder is intact and IMEI is correct, its not too late. There are a number of apps and programs to backup your imei. Ktool is one of the best and simplest to use. Also try EFS pro.

Mate when people buy a phone, they don't expect that their phone's EFS will get meshed up. In my case I have Galaxy S and my wife has Galaxy S2. She has been using her phone for year and half, no major problem. Last week it suddenly lost the network connection. I tried different SIM but still no good and started searching to resolve the issue and I found how to access IMEI. It was empty. She didn't do anything, no new apps installed. Mobile service provider can't help..
samsung galaxy note 2 lte 4g N7105
Hi everybody i'm new here i have a problem with my phone,my phone is rooted, 1 month ago i had this problem that my phone would not boot stay on samsung logo,i rebooted in recovery and say EFS failed,so i connected my phone to odin flashed a couple of roms but nothing worked, i saw that there was an option EFS clear so i did that but did not work either so i reflashed a rom and this time it worked but when it booted it didn't even ask me to enter PIN for sim and i noticed in about device there was no baseband and no network signal please help guys i would appreciate thanks.
Hi everyone! I know i'm not the first one who has this problem but i'm one of them.
I read and tried everything on what i could find about this, but i can't get it fixed! please help!
The situation:
I have a I9100 Galaxy S2, and it works fine, except for the cell phone functionality. It sais "Baseband unknown", has no imei number (also no 0049... imei), and i tried multiple EFS folders (i also have one from a friend who got it from his own Galaxy S2.). But no work.
In fact, i read that if you delete the EFS folder, it should autocreate a new one. It kinda did, but it only generates a bluetooth, upgaddr and wifi folder. Nothing more nothing less.
I flashed another rom, i flashed another phone image with Odin. I tried to erase all kinds of stuff with the clockwordmod recovery. But nothing helps so far.
If i'm correct from my standing, it looks like the baseband is broken itself. Why else wouldn't it even recreate the EFS folder? I'm starting to think that my original EFS folder (which i backed up before replacing it) was fine, but it's not even being read anymore...
Can anyone help me?
Thank you!
bump, still trying. Flashed a new clockworkmod recovery and with adb reformatted the efs partition as listed on xda somewhere. Then rebooted.
The Bluetooth does get a new mac address, so that part is good, but baseband still unknown and imei totally empty.
Also, the phone should regenerate the efs folder itself right? Well it doesn't. That means, it makes a bluetooth and a wifi folder, but that's it. No files or whatever...
Help please!!
m8 y u even delete the efs folder????? anywayz u got a backup so jus copy papte the files of efs...an flash stock rom....if u get un known base band then revert one step back --tht is flash a stock rom then come to present rom--then check///or u can flash cwm modems available suited to tht rom...but make sure u r pure stock--pda,modem,csc.....an yes copy the good efs folder on ext sd card too ,,so tht u can set same permissions like the ones ur copying to phone efs folder(sometimes the permissions change afta reboot)
i'm facing the same problem
Hi there.
Hope someone can guide me on this. I've been reading all the posts related to unknown imei, lost efs folder, etc and tried several things to solve the problem, but anything worked out.
The phone got wet with some raindrops (very few raindrops). Warranty was lost because they told me the motherboard was damaged by water. At first the battery exhausted in no time and it didn't charged properly, but a couple of months later everything seems to be all right except that it tells there's no IMEI, and the SIM card isn't read by the phone. Later on I've brought it to another technical service where they've told me the motherboard wasn't damaged, but the SIM connector. They wanted me to pay a big amount of euros for such a little piece. I picked up the phone and decided to investigate by myself.
The actions done to the phone: I fisically opened it and applied a connector cleaning spray; then I upgraded it to ICS and finally rooted it. Then I tried lots of solutions that are posted in the forum, like the GSII_repair, busybox, backup of the efs folder via android-sdk, efs pro, etc.
The only thing about efs that I can read in the phone are two files: an efs.tar.gz and an efs.img.
The efs.tar.gz seems to contain everything needed to restore EFS folder: nv_data.bin, nv_data.bin.md5, etc.
I have no idea how to tidy all this mess up. I know that it's possible that the phone won't work again because of the rain, but I want to sold all the possibilities out before using it only as an ipod galaxy, and I resist thinking that if it was damaged by water the phone woulnd't work ok like it does.
What do I want? Trying to give it its IMEI number again and seeing whether it catches signal. Any idea on how to do that with the files efs.tar or efs.img.
Thank you so much.
Since you have some kind of an EFS backup, then you can use kTool, in the Google Play Store, to restore that backup.
kTool requires root.
Hi and thank you for the reply.
I've downloaded this hc-ktool and tried to restore EFS from backup via efs.tar.gz and via efs.img but anyone worked out. It still says "unknown IMEI". Any idea about why it didn't work?

Not really, I am still a noob in Android.
Do you have unknown baseband problem? If yes, then try flashing another modem via Odin.

In the baseband section it tells UNKNOWN, as well as the telephone number, IMEI, IMEISW and Bluetooth. D'you think changing the modem will change all the other unknown stuff? I'll try it anyway, thanks.

Nothing to do with the modem. I changed it and everything's still the same.
Still rounding the problem... I installed root explorer and I saw there is an original efs folder in the root of the memory, not in the internal sdcard of the phone. So, what can the problem be? Is the phone really damaged? Or do someone think is only a software matter (is the efs folder corrupted?). Anyone can help?

Hello all.
Yesterday i was trying to install the last version of Paranoidandroid but when phone booted, i noticed that it had no data connection.
So i tried to make a call, but when you compose a number and press the phone button i get the error "not registered on the net" (hope the translation is good as i get the message in my language Italian).
Reading here and there i was able to undestand that the problem is the IMEI: my IMEI is changed and it displays a general one.
The big problem is that i pluged in into my PC the Hard disc that i used to backup my data and it doesn't work.... nothing...All the data are lost...
Am i able to recover my original IMEI (i found some guide around the web to get back IMEIs for AT&T and Verizon S3s with no backup, but not International GT-I9300) without a efs backup or do i need to send it back to Samsung (already resetted counters and restored original stock rom)? If i need to send it back, will they fix it in warranty (i'm still warranty covered) or will they ask me for moneys?
thanks in advance.
Hi,
First, you must try to install the latest stock firmware corresponding to your country and do a wipe data/cache. In some cases, the true IMEI will be back.
After that, if it doesn't work and if you haven't an EFS folder backup, there are no solution to fix your problem. As you said, we can get back IMEI for Qualcomm based Galaxy S3 (corresponding to USA Market) but Exynos' Galaxy S3 used EFS folder containing nv_data.bin that packaged the IMEI number and cannot be write without proprietary software.
If you cannot retreive your IMEI with the first method, send your Galaxy S3 to Samsung After Sale Services. Be sure that your custom flash counter is set to 0 and the firmware is a stock one before try a warranty fixing. In some case, it's covered by warranty (if there are no flashing watermark) but they can demand you some money to do that if they think you have flash/root the device.

Already flashed the latest stock rom for my country and operator and resetted all the counters, guess my last resort is Samsung after sales service... let's hope they will not ask for money.
Like @lelinuxien52 said, we can't restore those devices. Next time you should make several backups of your /EFS partition and them put them to an online storage facility, like DropBox, Google Drive or SkyDrive.
Would have loved to help, but you'll have to:
A: Beg that you have an old dusty backup on your PC or SD card somewhere,
B: flash a new Sammy stock ROM (Download here: http://sammobile.com/firmware) and hope that that works,
or
C: Send it to your carrier and hope they can fix it. They'll probably send you a new device, but if you're lucky they have some kind of program which can generate an EFS paritition with the data from the stickers on your phone or box.
Agree with @familyguy59 : DropBox or Google Drive (why not Mega instead of SkyDrive !) is your best friend against EFS folder problem. Do not forget to save it when you receive your new/fix smartphone.
C: Send it to your carrier and hope they can fix it. They'll probably send you a new device, but if you're lucky they have some kind of program which can generate an EFS paritition with the data from the stickers on your phone or box.

To be honests the only lesson i learned here is: Keep that device as stock and stop messing around with it lol
It'a already wonderfull as stock, i had really no need to flash custom ROMs... it's just that i'm a flash-addicted user since my first android phone (Acer Liquid) but well... i deserved it i think ^^

Well then you missed something... You can and should mess around with it. Just be more careful.
(Check my description) I have created a universal Android tool kit which, in the next update, hopefully, will be able to back up the GS III's /EFS partition. Check it out, some time.
