[Q] EFS backup - Samsung Galaxy S II Plus

Hello, i performed an EFS folder backup using EFS Professional. My question is, why it needs Busybox to work? I must have Busybox installed if i need to restore the EFS folder? I'm on 4.2 stock and rooted.
PS: the backup went ok, no errors. There is anothe better way to backup EFS on gt-i9105P?
PS2: Restoring a nandroid backup, also restore the EFS folder?

there is very little chance that your efs folder will be blown up .. now that you have a backup , you need not need to worry .. while flashing roms and wiping dat , and restoring roms via cwm backup and restore you only need to restore the rom and not the efs folder backup .. if in case , you do not find your imei no. or your efs folder and stuff , you can at any given time restore it manually .. correct me if i am wrong but that is how it works . all the best and Happy Flashing

[Q] How to use Nandroid backup and what exactly it does restore?

Hello,
I have problems restoring from nandroid backup.
Here what I did"
1) Flashed ROM1 and Flashed Kernel1.
2) Installed all My apps which I use.
3) Took Nandroid back-up.
4) Flashed ROM2. Flashed Kernel1.
5) Installed all apps.
6) After 1 days reflashed ROM1 and Kernel1.
7) Tried restoring Nandroid back-up I created 1 day back.
AND IT FAILS!!
Everytime I did a complete wipe of all data and catch and dalvik.
Same happened with CWM and AmonRa
CWM: md5 sums mismatch!!
AmonRa: Oops! Something went wrong!!
Am I mistaken about Nandroid back-up? Am I doing something wrong?
Actually I wanted to restore all my apps and data related to apps. I took whole system and data and everything backed up in the option.
1 Nandroid backup means it reflashes your backed up system with all your installed apps i.e if you have gb rom and do nandroid backup it will backup your current system( in this case gb) with all installed apps at the time you did backup.
2 You said it failed did it display any error while backing your nandroid backup.
3 Never heard of a backup being failed, you must have messed up something.
4 Md5 checksum mismatch means you either had a bad flash or if you moved or replaced some file also backup from different recovery will not work if you backed up from cmw then you cannot restore from amonra recovery, did you change recovery after backing up if you did then it wont work.
5. If you want to backup your apps and data next time try backing it with titanium backup root.Open titanium backup and press batch and then press backup all apps + data.
6. After flashimg new rom install titanium backup root from google play and press restore all app+data this will restore your apps with data.
7. If you use nandroid backup then your rom also changes to the rom that you had while backing up.
hope this helps
Go to your SDcard.. search and go to clockworkmod folder.. go to backup.. now whichever file you see.. Rename it xyz or anything WITHOUT any space!!
Try restoring then!!

I hadn't change anything but the name of the folder with some appropriate name like "CM-9.1.1 Final + CandiedIce Kernel + Apps", so that I can recognize it when I need it. No changes in the 5-6 files of recovery.
Didn't try restoring CWM back-up with AmonRa. Tried Amonra to Amonra and CWM to CWM. Failed all times (almost 5 to 6 times).
Does making folder name without any spaces in between work? If it's so, it's weird!! Is it that way? Should the folder name has to have NO SPACE?
"clockworkmode > backup > CM-9.1.1 + CandiedIce Kernel + Apps" - won't work.
But "clockworkmode > backup > CM-9.1.1+CandiedIce_Kernel+Apps" - will work??
Also, as known CWM couldn't back-up sdext. But otherwise No Error. While AmonRa did all back-up without any sort of error.
Dude.. just do it. WITHOUT ANY SPACE.. if you want to restore!!
And keep a small name!!
Eg: cm9.1.1.candied.ice
Dont use any special characters like $ & #
Thanks

Use a custom recovery to backup. You can find them at galaxy nexus forum on xda
Yes, it restores everything. Nandroid backup is 1:1 copy of your entire phone memory. It will even restore your messages, call logs, accounts etc

So any NANDroid backup is 1:1?
Does that mean that NANDroid also wipes all data?

yes, is 1:1; if you restore a nandroid it will take the same space as the rom you backed up, and no, if you make a nandroid backup, you won't loose any data whatsoever, you still can continue using the rom you backed up, but if you are going to restore a nandroid it's better to make a full wipe, like if you are installing a rom, that's the way i do it...

No, I didn't mean that you'd lose data when making a backup. That defeats the point of making a backup in the first place, lol.
I was talking about when you restore it. And from what you just wrote I assume that files that aren't overwritten when restoring remain. Similar to how you can flash a ROM "dirty".

Files will be overwritten. For example, if you make a nandroid, then update an app, when you restore that nandroid, you will restore the previous version of that app.

Yea, exactly how I thought it worked. Thanks for confirming that for me.
guys i have some questions.........
1) nanadroid backs up all system apps and saved data like messages, phonelogs, contacts, saved settings right ??
2) if I flash a new ROM and then want to go back to the previous state by flashing nandroid backup, does it unroot my device?
3) I backup system apps + data by nandroid backup and SD card apps by Titanium Backup. Is this right ??

4) If I have a backup of stock ROM then flash a custom ROM like CM, system files will be different in CM. SO when I restore the stock ROM, files that are new to CM will still remain right?
sorry for asking noob questions..........I'll really appreciate it if u guys answer this
Hmm

do you use cwm recovery or twrp idk about twrp but if you are using cwm go to the cwm recovery go down to backup and restore now backup it to sdcard1 (sometimes its shown as backup to external sd card depends on your phone what u use) or just press backup it backups your current rom and your files and now press restore and chose your restore file or if you backup it to your sd card you can do the same thing just chose restore from external sd card and chose your restore file :good: done :good:

[Q] EFS Restore Gets Erased After Reboot???

I got the EFS backup, My efs.tar generated by EFS Professional is about 20MB, reasonable size for the whole EFS Folder???
Why does it get erased after i re-boot?? How can I Restore, and keep the restore in???
Note: N8013
Stock, Rooted ROM, ''Factory Mode On''

[Q] Some questions about the EFS folder

Hey, I'm new to flashing ROMs. I've heard that backing up your efs is important, so I made a backup using TWRP, and copied the efs folder using ES File Manager to my SD card, and then to my computer. Will I be able to restore the imei and other things by either using TWRP or copying the efs folder back to the root of the phone? Just a question.
Unless you specifically selected EFS as part of TWRP backup - no, you won't.
If you did select EFS for backup in TWRP - yes, you will.
Thanks for clearing that up!

[Completed] Backed up with CWM navigating to the folder in restore says "no files"

Hi i need help ASAP,
I backed up my phone with CWM it made a folder as a backup.
When I tried to restore the backup I navigated to the folder and it showed me inside that folder (like there are no files) instaed of starting the backup procces.
one more problem is that now i flashed another ROM with TWR and I didn't know it will be with TWR so I am not sure I can backup CWM with it.
please refer to my 2 questions as it combined.
Can you clarify if CWM is able to restore the Backup ? If its not, then the backup was not made successfully.
To your Question, are you saying you flashed TWRP Recovery and then flashed the new Rom ? If that's the case then the CWM backup can't be restored by TWRP.
EDIT - I should caution you that it is not a good idea to restore the backup made by one Recovery with another.

Recover efs manually with old Backup

I lost the funcionality Phone in my N8000. I think i lost the imei e someone more else. How can i restore my efs? I have a backup of my efs in format zip and format tar made 5 years ago ( i dont remember what application i used) , but i can not install via Odin or via Twrp, said Invalid Zip format on checking Digest File. I think the problem is checking the md5 generation that is not compatible with Odin and Twrp.
Someone can help me to restore the /efs partition with old backup. Thanks
see your identical post .
I resolved this situation, using Solid Explorer and Qute Terminal with root.

Thanks
It is not solved, when reboot the system, the imei of phone, N8000 is another, is from another file from i used to recover.
Manually from my backup what files and permissions i have to copy to the /efs in root of my N8000? First i copy nv_data.bin, nv_data.bin.md5 and the folder /imei and works. I do not known the original permissions of the files, perhaps now the problem is this.
Someone can help me?
Thanks
With this guide "[GUIDE] Recover your IMEI in 9 steps. " https://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021 , i resolved my problem with imei, no problems with reboot, but now i did not have access to Wifi, i can not connect to my Wifi Network.
Someone can help me, how can activate wifi? What files i need to copy from my backup? Before clean the /efs i made a backup the old efs.
Thanks
