Efs issues - Sprint Galaxy S 5 Q&A, Help & Troubleshooting

Some how my efs folder contents got deleted while flashing, or restoring a nand backup. Nothing crazy, but now only data works can't call, or receive texts. I've found some topics on this, none pertaining to the S5 how ever. So long story short my efs folder is empty, and I have no backup. I was wondering if there is some type of fix like this - http://zidroid.com/how-to-fix-failed-to-mount-efs-for-galaxy-s3-gt-i9300/
I've also tried to reflash stock firmware via Odin with no luck.
Thanks for any help.

In your nandroid backup, did you select EFS?? If you did you can use Nandroid Manager Pro and extract your EFS files and be good to go!

Unfortunately my nand backups didn't work I tried restoring efs with them, and had no luck.

Flash the APN fix in the sprint Android Dev section brotha.

APN flash did nothing. But was able to call tech support, and did a "CHLS Refresh". I'm able to make/receive calls, and send/receive texts. However my efs folder is still empty, but everything works...

Every time I reboot my phone it still says I'm in Factory mode, efs folder is still empty. Is it time to bring it in? Lol

Finally after trying a few things I finally figured it out, and now have files in my EFS folder, and no longer boot into "Factory Mode".
Here are the steps I used -
Boot your device into recovery mode
Connect your device to PC via USB cable
In recovery mode Choose “mount and storage > mount /system”
Open ADB command window and type :
Code:
su
mke2fs /dev/block/mmcblk0p12
mount -w -t /dev/block/mmcblk0p12
reboot
Credits go to http://zidroid.com/how-to-fix-failed-to-mount-efs-for-galaxy-s3-gt-i9300/ I just changed a few things to work with the Partition Table of the S5.

Maybe it's to late, but my galaxy s5 sm-g900f is dead. I've back up the efs partition with Samsung Tool Apk... and posted it here on mega if needed i can send you by private message.

Titanium Backup problem

Hi, before you claim re-post I have searched all over the forums for this but haven't found any to fit my situation. Right now, I have a myTouch Q from Tmobile and when I rooted my phone a while back, I installed titanium backup to backup all my system apps before I uninstalled the unnecessary ones. I want to unroot my phone now, but before I do I wanted to restore all my system apps (browser, music, calculator...I used things like dolphin, songbird, and realcalc). When I try to individually restore the backups it just spins endlessly attempting to restore the app. I have tried checking/unchecking USB debugging mode. Any ideas as to why this is happening?
Go to Preference-->App Processing mode
And change it there is three modes choose the best

Happened to me once....when you restore an app...it keeps on loading....
What i did was...
choose restore...it will load... . Then when you feel restore should be done,depends upon the size even.....press home button...the app should be restored...to restore another app force stop titanium backup from applications....Hope it works for you

[Q] No signal / No mobile network

One more thread...
I've spent a lot of hours on this (and another) phone with no signal, or no mobile network detected. Finally I got to the root folder using SuperManager and got into the EFS folder. The IMEI folder is blank. The ROOT folder contains other subfolders, and I have an nv.log and an updated_filesystem file on the folder itself.
I tried Helroz's apps and I get issues (Galaxy S Unlock). Backing up the EFS folder returns an error. Superuser shows it granted permission for the app.
Current IMEI is 0000000000000.
Now I have another phone here, and it has IMEI and i unlocked it but... still, no network, after battery pull and different modem.
What gives?
You should call your local service provider and do a imei check, because if you dont get service or network it may be listed as stolen.
Flash back to stock using heimdall, it'll fix your imei. After that, root your phone, download the efs pro tool, and you can use that to backup and restore your efs in the future

How to Backup & Restore IMEI (Noob Friendly)

In this tutorial I will show you how to backup and restore your imei if it gets corrupted or lost in in some type of update.
1. Go to http://pikachukaki.googlecode.com/files/ToolBox5iromV1.0.4.2.apk and download 5iromtoolbox
2. Install the app and open it
3. Click on IMEI Backup and wait a bit, could take some time
4. After backup, to check if it was succesful, go to /sdcard/5irom. There should be a folder in there called imeibackup with 3 IMG files called 5.IMG, 10.IMG, 11.IMG.
5. Backup the 5irom folder on your computer for safe keeping.
6. If you wish to restore your lost/corrupted imei, place the 5irom folder back in the original directory, open the app and click IMEI restore.
7. Reboot your phone/tablet and to make sure the restore worked, go into dialer and type *#06# and it will display your imei
8. Enjoy your fixed galaxy s blaze 4g t769

[Q] ADB restore ends prematurely on Android L

Hi, I'm using a google play store Nexus 5, and trying to restore a ADB backup (.ab file, not pulled files) and for some reason it keeps saying 'restoration ended' on my phone while the computer continues to send data. Anyway I can force it to continue/ restore the .ab from recovery?
Thanks very much for your help, I've searched the forums but could find little on the matter.
Because "L" isn't meant for daily use and is full of bugs...

Thought as much, well, there was nothing really too important on the backup anyway. Cheers for the quick reply!

I've had issues restoring .ab file backup on my nexus 5. However it works flawlessly without the ".ab" i.e naming my backup as say "backup" works where naming it "backup.ab" fails.

[Q] Restore nandroid backup

Hello Guys,
Since I totally bricked my old Nexus 5 16GB(KTU84P) I am going to get a new one. But I am thinking of getting the 32GB version this time.
Now before it got bricked I made a full nandroid back-up with the help of the Nexus Root Toolkit and TWRP.
Now here are a few (stupid) questions:
~Is it possible to restore a nandroid backup from one phone to another and even in this case a "different" version of the phone?
(I've skipped over this thread real fast http://forum.xda-developers.com/showthread.php?t=728266 which says it is possible for phones of the same model)
~If it is possible how should it be done?
~And well if the first question isn't possible, is there a way to read out out the created back-up files which TWRP created and manually restore them(preferable the data partition)
I hope you guys can help me out
Kind regards
Yes, you can do it. Just make sure you're not restoring the efs partition or you'll have another brick on your hands.

Also don't use toolkits next time. Please use the manual methods which are better, safer and teach you the basis you need to recover.

When you run into issues, as many do after nandroid restoring from one device to another... Wiping and Flashing stock with fastboot is the Fix.
Thought I'd cover that up front. ?

Hey guys sorry I didn't answer immediately, but after I saw the posts I immediately ordered a new Nexus 5 (32GB this time). I got it delivered today and like you said I've done the unlocking, custom recovery and rooting manually this time instead of using a toolkit. Which was to be honest way easier than I thought but also way faster than using a toolkit.
But now I've kinda run into a other 'problem'
When I restore my previous made backup (the one from the bricked phone) I first of all only get the options to restore the 'system' partition and the 'data' partition (which is totally fine cause those are the only ones I actually need).
But when I restore the system partition a lot of apps crash on default(It is basically bricked then), and even when I just restore the data partition the same thing happens. (To be completely fair this problem might come from the fact that I used the MD5 verification option when I made the backup but I can't really remember that. but some of my backup files end with the .MD5 extension) Saying this I also used the restore option with check MD5 verification, but needless to say I get the message that they verifications don't match.
So here are a few questions again.
~Like I said before I only really care about the 'data' partition, Is there an option that I still can use TWRP to restore it properly?
~If the above is not possible is there a manual way to read out the made backup file using a program like 'Ext2Explore'(This crashes though when I open the file)
Or did I just completely screw up by checking the MD5 verification?
Once again kind regards
p.s. If the problem isn't clear tell me and and I'll try to explain it in a different way
You missed quote from post #4. ?
I believe that with a new device.... It should be a clean start. And I read post after post in different device sections of issues from restoring from other devices.
And so I never recommend it. It can, possibly, bring lots of issues.
But to each their own.
Good luck. ?

Ohh right, sorry I completely read over your post my bad. But then again If I have to wipe the device wouldn't that totally remove the point of restoring the data partition ? or is the wipe command just for the system partition?

What I'm getting at, is don't restore the data partition. You can try, but I often read of lots of issues doing it.
Yes, I implied wipe the device clean. Flash stock. Start fresh.
Now if you had a titanium backup of user apps on your pc... I'd say you'd have a much easier time restoring that to the new phone.
Just my 2 cents of course.

I made a clean start yes. Unfortunately I don't have a titanium backup and I get that storing the data partition to a other device isn't a good idea. But well I never had the intention of making a back up and restoring it to another device but unfortunately my other phone got completely bricked. And yes in hindsight I should have made backups in multiple ways.
But like I said I don't really care about the system(including the apps and app settings) it is literally all about the actual data (pictures and stuff), that is also the reason why I asked if there is a way to manually read/open the back-up files.

Well that certainly is a bummer, and also very misleading from the nexus toolkit. From now on I shall back-up my phone more properly and well stop using those darn toolkits,
Thank you for your time.

Did you make an adb backup in the tool kit? That would have your pics. But a flashable nandroid you flash in recovery would not.

Would Nandroid Manager be what you're looking for? EDIT: as above, it won't find and restore any of your pictures/music, as a nandroid backup does not include any of these. There is a chance you find and restore your apps and settings if you so wish. I've used that app before.
Incidentally, I successfully transferred all of my data and ROM from one Nexus 5 to another (had to RMA)
The process I used is:
- Unlock bootloader, install custom recovery on new N5
- Nandroid backup on old N5
- Copy whole /sdcard partition from old to new N5. Basically, all files and folders on the 'root' of the drive when connected to PC. This included all photos, music and the nandroid backup itself.
- Restore nandroid backup on new N5 (only /system, /data and boot.img / kernel), as if you were restoring any nandroid backup really. Though do not restore efs partition as advised above (it wasn't backed up, but worth mentioning again anyway).
Took a while, but the ROM and settings were carried over successfully.

Nope, I did not. And the ignorant person that I am just assumed that the nandroid backup would back up everything since the toolkit says "Make full Backups"
So well I guess I just have to accept the fact that I lost those things

I am assuming that you used a tool like Android File Transfer.
So what I'm trying to do is the same thing, backup my entire old N5 32GB as I had also requested an RMA of the device. Is it accurate in stating that you want me to copy every folder that shows up on the AFT window (Note: I am using a MAC) and copy that onto a folder on my computer. Then copy over everything on the new device (bootloader unlocked, rooted, same TWRP version installed) and restore via the Nandroid backup from my old phone (which was also transferred as indicated above).

I didn't use AFT, just plugged straight into PC, sorry no experience with Mac
Basically both phones were connected, and I copied the whole "/sdcard" straight from one phone to another, without making an initial copy to the PC
You want to replicate the same file structure
