How did you install ADB Drivers?Will you give me the correct detailed procedure?I also am facing the same problem in my Note 2.Waiting with thanks....
[Galaxy Note II Android Development] stanley08:
I hear Galaxy S4 and Note 2 have the same efs block number mmcblk0p3, So this procedure should work on S4 too. Please confirm this! :)
[Galaxy Note II Android Development] lskwl:
Hi James,

you don't need to worry about the last error, that is just kind of a cleanup action.

You should get the file "efs.img" file with a size of 20MB in the same folder as where you run the script from.

If you get the file everything is ok.

And it should be there, because the output shows that it was copied from your phone to your computer....

If you have more questions please write in the correct thread, because this script has nothing to do with the OP post and I dont want to spoil his thread... I won't monitor this one any longer.

[MENTION=4702699]stanley08[/MENTION]

I don't have an S4 and can't test it, but if the block device is the same and the size of it is the same it should work. You can try to make an backup, the backup is non destructive for your phone and does not make any changes on it.

Hi,

I have rooted my Note 2 - N7100 using "Root with India Stock Recovery ROM"

Then I run this Backup EFS bat file and get the following error.

Backup EFS

Press any key to continue . . .

--- STARTING ----

--- WAITING FOR DEVICE

* daemon not running. starting it now on port 5037 *

* daemon started successfully *

--- Backup efs image ---

remote object '/sdcard/efs.img' does not exist

Press any key to continue . . .

Can you assist me on this.

thanks.

Found Solution:

My Phone was requesting for "Approve Root Access to ADB Shell" which I had missed out before. On providing the ROOT access to ADB Shell, the EFS.IMG was backed up. Thanks

The backup has been completed. .. u can restore the sane file if anything goes wrong with your imei
[Galaxy Note II Android Development] tweeny80:
For me, following OP instructions worked, end result was EFS file of type 'Disc Image File' 20 MB size

I will guard it with my life. Hearing others explain how a ROM flash wiped theirs makes me nervous...I am about to flash my 1st ever GT7100 ROM wish me luck. My 1st phone was a Nexus S, and EFS corruption wasn't ever discussed in the forums. Is it not an issue with Nexus phones?

Anyways thanks OP
[Galaxy Note II Android Development] mozilla008:
Can I restore the efs.img using the CWM?..
[Galaxy Note II Android Development] Gandicela:
I think you need to run the script, not CWM. The files in the first post can do that for you.
[Galaxy Note II Android Development] mozilla008:
Ok thank you.. But what if the phone won't boot in the main screen, is it possible to restore using CWM?
[Galaxy Note II Android Development] Gandicela:
I think CWM does not do that for img files. But I could be wrong. Personally I never did so.

Hey guys is there any way to restore IMEI from download mode? What happened is that i tried flashing ARHD coming from WanamLite 3.8. Did a full clean wipe install tho..after booting up, i noticed my IMEI wasnt the one i had. So tried restoring my IMEI from my EFS backup using Terminal Emulator. Then after rebooting my phone was stuck in bootloop. And now thats all it is. It just wont boot up. I tried restoring to stock via ODIN and still phone wont boot....Any ideas?

[MENTION=3362665]corvux360[/MENTION]

what i did i to flash the rom i want then i did extracted the tar.gz file so you've efs folder extracted so after i've flashed the rom i deleted EFS folder in my phone and i reboot you find no lockscreen and some words in yellow copy EFS backup folder you extracted before to the same location you deleted your device EFS folder then reboot service now should work if not so apply the following commands in terminal emulator line by line and press enter after every line:

su

rm /efs/FactoryApp/keystr

rm /efs/FactoryApp/factorymode

echo -n ON >> /efs/FactoryApp/keystr

echo -n ON >> /efs/FactoryApp/factorymode

chown 1000.1000 /efs/FactoryApp/keystr

chown 1000.1000 /efs/FactoryApp/factorymode

chmod 0744 /efs/FactoryApp/keystr

Descompact .tar.gz

To descompact .tar.gz I use this:

On Pc, black screen:

adb shell

gzip -d /storage/sdcard0/efs.tar.gz .. or .../storage/extSdCard/efs.tar.gz

Now I have efs.tar only on device.

If extract this tar I have efs/files. I can copy efs/files to root/efs.

I verify permissions and alright (in my succeeded cases).

On device whit Shell Terminal Emulator work well also.

anyone please. thanks in advance.
[Galaxy Note II Android Development] Formhault:
The efs.img the backup .bat did is 17.2MB in size. Is that okay?

I'm asking because when I backed up the EFS in my previous Samsung phones (S2, Note1), the file was 20MB in size.

EDIT : Pff... I re-did the operation and the file is now 20.480KB (20.0MB) in size. :eek:

But Now I'm using APSO Rom, i can not restore EFS, my phone have no IMEI, the restore.bat say waiting device, while i enabled USB Debuging mode on my phone, and Device Manager say have Samsung Android ADB interface

What can i do?
[Galaxy Note II Android Development] 3to4:
I confirm this also works for N7105, or at least it seems to have worked. It created a backup file, although I have not yet have an occasion to restore.

Question

Hi all.

Is it possible to restore the efs image from another device (N7100)?

Both of your device will be banned soon if you flash from other device, as well in almost countries it is illegal.

[Galaxy Note II Android Development] vishaldongare:
i hai had rooted my phone succesfully. i have already backed up efs. but then i was trying to install twrp on my phone.nd it didnt boot. so i flashed the stock rooted firmware of 4.1.2 through odin.But after that i am not able to get any network and my imei no. is also messed up. tried restore efs method but that too with no luck.I m really frustrated with this problem as it is a new phone. i have searched all over the net but efs restore is the only option i guess. please help !!!!:(:(:(
[Galaxy Note II Android Development] dr.ketan:
May be you have flashed old rom. And backup you made was on newer rom.

If so then get multitool from my signature and flash new modem with that.

thank you sir for your advice,it worked and saved my day.And the tool you have created is just awsome!!!!!!!:good:

Can anyone list out complete contents of a efs backup.All folders and its values.

Did a backup in August of this year, my very first.Thought I lost it when I couldn't locate it to enable imei/sn/service state and mobile network not connected issues after:

1) Trying out CM11

2) Trying out SupremeBean

and then flasing back to stock 4.1.2 not my actual backup.Random stock firmware ends with XSE.

Eventually used guide from dr.ketan and fellow xda member sora9009 to flash modem mf1 and get back a working device.

However certain expects of corrupt device information remains:

Imei-back to original

S/N-back to original

Service state-in service(what a relief!!)

Mobile network state-not connected (as it was when corrupted)

But I am able to make and receive calls.

My efs backup consist of 14 items:

bluetooth folder-/bt_addr 0kb

drm folder-/play ready folder-/0002.PRV 0kb/DXDeviceKey 0kb/DXSecureDB 7.1kb/DXSECUREDB-secondary 8.3kb and NVS 0.1 kb

factory app folder-/baro_delta 0 kb/batt_cable_count 0 kb/earjack_count 0 kb/epen_count 0 kb/factorymode 0 kb/fdata 0 kb/hist_nv 0 kb/hw_ver 0 kb/keystr 0 kb/prepay 0 kb/serial_no 0 kb and test_nv 0.3 kb

imei folder - mps_code.dat 0 kb

wifi folder - (empty )

00000000.authtocont 0.1 kb

efs.img - 20 mb

efs.tar - 2mb

gyro_cal_data 0 kb

h2k.dat 1.1 kb

nv_data.bin 2 mb

nv_data.bin md5 0kb

nv.log 2.3 kb

wv.keys 0.2 kb

Could someone make a comparison to what they have with mine.The efs backup was done via TWRP recovery and as you can see there is no .bat file anywhere.
[Galaxy Note II Android Development] dogmatism:
Anyone who has the error

The system cannot find the path specified.

The problem is adb.exe is out of date... you need to update it in newer android versions.

you can get it, just search xda for, Minimal ADB and Fastboot /... replace the adb files

adb.exe

AdbWinApi.dll

AdbWinUsbApi.dll

in the folder "files1"

I don't know if I'm supposed to be using N7100_EFS_Backup_Restore_WIN.rar or SAMSUNG_N7100_EFS_BACKUP.zip

I am trying to use SAMSUNG_N7100_EFS_BACKUP.zip

It's not doing the tar backup:

Command: bin\adb shell su -c "busybox tar cZvf /sdcard/GT-N7105TADTGY_N7105ZHDMI1_R31D3017QCT_

EFS.tar.gz /efs"

Output:

unknown option -- Z

BusyBox v1.21.1-jb bionic (2013-07-25 21:23 +0100) multi-call binary.

Trying to backup with an old CM ROM before it is screwed up any further so busybox is likely out of date.

Also subsequent backups fail because filename is too long (keeps appending the variable) and fills the device SD card with backup files not being deleted after.

Tar command allow gzip compression trough the -z argument (lowercase)

Thanks!

I thought I had lost my 2nd device in succession owing to EFS issues, but your tool saved me the blushes. For those having EFS as IMG file you can get it restored using option 3 on clicking the executable in SAMSUNG_N7100_EFS_BACKUP folder.

Thanks a bunch! Now backing up EFS your way ;)

Thanks, Sir. But yes I can't use it due to unique IMEI. I already have my EFS backup but still the IMEI is 004999 generic numbers. Question is, how can I edit my efs.img so I can append my real IMEI?
[Galaxy Note II Android Development] 01101001b:
Thank you so much!

I lost my imei nearly one year ago. An old battery hiccup made the "magic" to spoil the efs partition and kaput! no more imei. Since then I was reading and looking for solutions but unable to hit the nail.

I had made a backup (thank goodness!) but for some reason I only found errors when trying to restore it.

Long story short, your linux solution guided me to the final bit of information I needed to restore my phone from that "quirky" backup. And It worked. Amazing.

I've registered in xda just to say thank you so much! :victory:

Project Roadrunner would be pretty sweet and I hope the Google Play stuff is implemented to countries other than the US, because I am pretty upset over the fact that I couldnt buy magazines (for an example) in the Google Play store.

Also that customization centre caught my attention. I hope they let the user change features like the wifi icon, cell signal and battery colour to whatever you want. There are loads of homescreen UIs that I wanted to do but it just wouldnt look good with the blue icons.

Back on topic... Loving project road runner, but I have no idea how they are going to achieve this as the main battery drainer is the screen. So the only way around it is to change the screen technology or add more battery...

I'm curious and stocked about this too, yes I know it's a rumor but still. The CDMA version also has an LTE radio to contend with. I'm excited by the effort alone.
[Samsung Galaxy Nexus] crixley:
Not true at all....

You can streamline code a lot to tweak battery life substantially.
[Samsung Galaxy Nexus] zephiK:
It's a incremental Android version. It is not specified for one device (or any upcoming devices). It will be done via software through optimizations of line of code; definitely impressive if it is true. Android and Me is a reputable source and have always been accurate when it comes to their rumors in the past with Nexus rumors.

Anything is possible :)
[Samsung Galaxy Nexus] a12m4nd0:
"New Nexus Program

Rumor: As previously reported, any manufacturer can produce a Nexus device or a Nexus version of an existing device. They work closely with Google on the hardware and driver details (there is a more efficient solution for this in 5.0), but Google is responsible for the updates (don’t know how the carriers factor in). The phones don’t necessarily have to have “Nexus” as part of their name, it works more like a certificate like “HD Ready”.

The devices have to fulfill some basic requirements. The phone has to ship with a stock version of Android, it needs to have the hardware power to run all “Nexus Games”, and they have to support Google Wallet, aka have NFC.

There are two carrots on a stick that probably make the Nexus brand a huge selling point. Google Play gets expanded with a media streaming service component and there will be games that only work on Nexus devices. The streaming service uses the secure memory, making it harder to pirate the content. No word of the type or source of the media, but it seems to be a big deal."

Although I am definitely excited about the features (notably Project Roadrunner and the Customization Center), this is a wonderful initiative by Google. It seems they are attempting to address the fragmentation issues by incentivizing OEMs to carry stock Android and, thus, cutting down on different versions of Android floating around. All new handsets carrying the latest version would get rid of what is arguably Android's greatest flaw. This could be huge if it works well.
[Samsung Galaxy Nexus] @rbiter:
But the fact will still remain that the screen will still use the most juice, yes? Some of the chip sets on android have proven pretty battery sippy, but android itself needs a little more gusto in the HP department to run comparably to iOS and WPx. Screen and battery tech still needs to change dramatically to make a noticeable difference. Amoled screens don't help either. I very much like apple's very accurate displays. Almost to the point I wish some OEM's would go for that, but amoled does one up in the contrast department which can be a lot more beneficial in a few situations. I would like to see a phone here and there released with amoled/slcd options. I would guess that the current galaxy nexus would see almost an hour extra screen time if it used LCD screen.

...
[Samsung Galaxy Nexus] clj575:
Lol..back on topic fktard.
[Samsung Galaxy Nexus] albundy2010:
Screens will always use the most battery overall. That does not mean that it should be the focus point to improve the overall battery life.

Many android devices have LCD screens like Apple. That is not the difference. iOS is incredibly efficient compared to Android. It is software. The iPhone 5 has a 1400 battery only. I don't want to hear any fanboy nonsense either. No widget / multitasking nonsense.

Take any android phone out there. Disable all widgets. Delete all unnecessary stuff from /system app that you want. Go to dev options and set it to allow no background processes. The battery life is just sub par compared to iOS. Don't be a fool and go oh my note or razzr max with 3000 or whatever barriers last longer. Look at 1400 vs what android equivalent to get equal battery life. Imagine a Android phone with the battery the size of the iPhone.

Apple sucks at a lot of things. Battery efficiency is not one of them.

I hope Google does but some serious effort into making android more energy efficient. Stop just relying on smaller more efficient soc's and bigger batteries.
[Samsung Galaxy Nexus] Jasonhunterx:
