[I9003] Request for EFS backup and Restore

I updated to XXBK3 as per the steps mentioned and everything went fine. When the phone booted, the simcard is not getting detected. I have factory reset the phone, changed the sim, tried my sim on another phone (works on another) but not this one.
Revert back to DDKB2 but still sim card is not getting detected. Kindly assist
Update: I have lost all folders in efs folder after flashing XXBK3. Unfortunately i dont have backup of efs folder
The only option left with me now if service center. Since there is no post for efs backup and restoer, i would request if someone can post settings/commands to backup and restore efs.

Hey, maybe you'll laugh, but there do not give any simcard wrong side. Once I flash phone at night and I'm still there giving the wrong side

I didnt understand you.
What i mean is i dont get network and when i try to open Mobile APN, i get message " Please insert SIM..."

This can happen if you have selected the option Phone EFS Clear in ODIN while flashing FW. This would delete the efs folder.
Follow my guide that I sent you for future. I have already backed up mine, but hope I wont need it.

What is the /efs folder? Should I also back it up? Only that folder or all folders under root are to be backed up?

Efs folder contains information about your Phones IMEI no. If you clear it or corrupt it you lose your IMEI and it can only be restored by Service centre if you have not backed it up. Just copying the folder is not enough. You need to back it up in the form that it can be directly flashed to your phone to restore the IMEI and to put your phone back in usable condition, as in india service providers do not support phones without IMEI nos.

Dude can u give us a walkthru of how to back up efs

Is the link given by manu1991 okay in your opinion? According to Post#2, "An alternative to the backup part is to use Root Explorer and zip the whole /efs folder onto your external sd card. (or wherever you want)". Is this possible and reliable? I tried the option to zip folder in "Super Manager" but got an empty file.

No root explorer should not be used to back up this folder. Follow the link and back up your efs folder.

Ok, I tried this and made the tar.gz file directly in my external sd card. I got a file of size 35Kb? Checked with 7-zip, seems to contain all files. Also made the .gz file using terminal emulator and got same size. In Super Manager the /efs folder seems to be 5Mb in size. I also extracted the .gz file and the uncompressed size is indeed about 5Mb. Can it really be compressed to 35Kb or is there some mistake?

yes, it can. If the files has a lot of zeroes inside. BTW here is only 3 files are very big:
nv_data.bin, .nv_data.bak and .nv_core.bak and as I can see they are have a lot of zeroes.

Yes it is compressed. Just pull out the efs folder out of the archive and see check the size, its 5.03MB for me.

Thanks falex and trip
I also made image of stl3 and it is about 6mb.

EFS / IMEI changes to Fake frequently.
With regards to your post on EFS restore, thanks for the excellent instructions I managed to get IMEI back but noticed that it gets changed quiet frequently when I am on any version of Gingerbread so I downgraded my self to Froyo and I notice that the IMEI doesnt change, Could you kindly advise me so to get it working when I am on gingerbread. Does it have anything to do with bootloaders. The restore method I used is to flash via Odin and no other commands there on.
ThanK You In advance.

i have the same troubles
i try many methods
last i failed
now i just play t959 as a pda

I believe the Nitrality app has an EFS backup feature

Good morning from Argentina!
I have a problem to restore my /EFS I have Froyo LUBKB1 (Argentina) coming from KPQ and the /efs is broken.
I have a backup from a functional EFS directory but when I try to copy it with Root Explorer, it seems that it copies it but when I reboot, EFS directory is empty.
Is there any possibility to create the .img with ADB from a directory which is in the sdcard?
Regards

IMEI help

i have lost my IMEI like 3 times before and all from dropping my phone and the battery falling off but this time its different.
i use to be able to just restore to stock and it would pick up again but this time it doesn't want to work.
i actually copied my efs folder to my sd card and only to my computer for save keeping + used efs pro tool to back up my efs on my other xp computer
problem: don't know how to restore efs folder
what i tried:
-efs pro - doesn't detect my device so i cant restore it
-replace efs folder - i deleted the efs folder in internal and replaced it with the copy i have in my sd
-restore to stock using one click

update
when i open the efs file on internal it has a folder named lost+found. i try and delete it but it says it can't be deleted. i copy the efs from sd card to internal and it has all the same files as the one on the sd but it also has the lost+found and i still can't delete it
any thoughts would help

Sounds like you've done all the steps that would normally work. If flashing stock didn't fix it you might be looking at a hardware issue. Before we jump to that conclusion though DL super manager from play. Once that's done go into setting in SM and enable the root function. Now backup two levels to root of phone. Go to efs folder and delete it(long press it for the option). Go to your sd card and copy the backup efs folder. Go back to the root and paste it. Reboot. That has worked every time for me. If it still comes up null try pulling that battery and holding power for 20 seconds. Then reboot. If you still have nothing enjoy your new MP3 player.

i have tried that on es file explorer but ima try it on SM. i tried it on SM and it does the same thing as es file explorer except it doesn't overwrite the efs file on root.
when i long press to delete the efs file on root is still there and it has one file that says "lost+found". unlike SM, es file explorer pastes the efs from my sd to the root efs file but it also includes the "lost+found" file with nothing in it

There is nothing in lost+found. You need to give SM root permissions then switch to R/W for the folder. Left soft key will get you there. If it's R/O nothing will happen.

when you delete the efs file in root is the efs file in root still suppose to be there? cuz mine still is with that lost+found.
i switched over to R/W but it still doesn't write to the efs root file.
my steps:
open SM app
- went to file maganger section
- open file maganger
-check R/W
- go up twice into root
- long press on efs file and click delete
- click on to delete ( efs file still there )
- scroll down and click on sdcard
- find efs on sd and long press copy
- scroll up and tap on up level
- click the paste icon
after that i check efs file on root and nothing is written on it, i even rebooted it after my steps just to make sure

As long as it says r/w next to the folder your in you should be good. It'll show it in the top left corner. Make sure it's r/w before deleting efs folder and again before pasting the copy from sd. If that doesn't work there's not much more I can do for you. Good luck.

thanks for your help! i got efs pro to work so i can restore my efs file but sadly it didn't work. you're probably right that it must be a hardware problem

[Q] What's on my SD Card?

I wanted to start this thread because I am having trouble, (and I assume other noobs are as well), understanding what's on my SD Card and how to navigate through it.
I've attached what I see when I open my device and check the internal storage.
My main reasoning for trying to understand all that's on my SD Card is because it's important! And because I'm trying to figure out where all my apps are stored. I recently installed the venom custom ROM, and since then have lost the knowledge of where my .apk files are stored. That's really what I'm after trying to find those files. I've searched every folder but still no dice. I used Titanium Pro to backup all my files but there is nothing located in the Titanium folder.
Can anybody help me identify where my .apk files are located?
I also have a few .apk files I wish to install on my phone. From what I've gathered the way to do this is to add them to where the other .apk files are located and then Fix Permissions. If I cannot locate my .apk files is there another file path I could save it to?
Lastly I have these two files I have not recognized before, BUGSENSE and .profig
What are these files?

So if you're downloading the apks off a website they'll be in the downloads folder if you downloaded then through Google play..they won't be on your sd unless you manually backed up them up through titanium

Right okay, so if I choose to back them up onto the SD card then my .apk file paths should appear? Because as you can see now I have no app folders on my phone (sd card) currently.

I've backed up my phone via titanium still nothing in there is an .apk file.
I'm also interested in keeping my phone clean of useless things (another reason for this thread).

As file explorer. Settings allow up to root allow root. Go up from sd card. System/data folder

If you go to titanium backup location on sd card and open it you will find what you looking for. Its pretty easy to restore backup in titanium app itself.....also a true backup should be done in twrp recovery as it backs up everything (file partitions,kernel,radio,apps) it will save a copy (known as a nandriod backup) on your sd card that you can recover if your rom won't boot or you just need to restore .

Make sure you enable writing to the root folder as well. System apps are in system/app.

Impossible to find my backup from Nandroid and Super Backup on PC

Hi,
I tried so much alternative for make a backup of my cell and to transfer it on my PC, but i dont see it when i browse from my PC. Nandroid, super backup and titanium are all configured to save backup to storage/emulated/0 but i can only find titatium save from my PC. Nandroid and super backup files cant be find
Im seriously out of idea
Thx

Check /data/media/0

I dont have this path when i browse from my PC
The only way for see my backup is when i did it from Recovery(philz recovery). I can find it in: /clockworkmod/backup
But the backup have a wrong date and time name

Read what maestro write. You have to use root explorer. It is in your phone's root directory.

I know where is my backup on my cell with file explorer. This is not my problem. The problem is i dont find it from my pc. I want to take my nandroid backup and to put it on my computer.

Ummm that's adb pull actually. You push to the phone and pull from it.
OP: Just use a root explorer and make a copy of the file someplace your comp sees. Copy it over to your comp with MTP then delete it.

Thx that work great when i move it to an other folder. But i dont understand why i dont see it from my computer in clockworkmod/backup when i see it in file explorer
EDIT: Now i can see it in clockworkmod/backup after i moved back it.... Very strange

Internal Storage on the Nexus 5 is /data/media/0, also what /sdcard is symlinked to. This is what is accessed via MTP.
CWM is outdated and uses the legacy location of /data/media/clockworkmod (note the lack of /0).
Therefore you cannot see it while connected to a PC, because you're viewing /data/media/0, not /data/media. It's also why it shows up on your PC when you copy it to another folder, its moved from /data/media/clockworkmod to /data/media/0/clockworkmod (but then CWM won't see it).

With nandroid app, you can decide where you want to make your backup. I tried /data/media/0 and storage/emulated/0 but i dont see it on my PC. Only in my file explorer from my phone. I can only see it on my pc when i move it to an other folder and when i move it back in /data/media/0(i move it with file explorer)
That what a found strange. Anyway, that workaround work so ill use it in the futur
thx guys

Titanium Backup Issue

OK so I am quite new to the rooting and restoring side of titanium backup. I have installed a new ROM and re-downloaded TB. When I go in to the restore part of TB nothing showed up for back ups. If I go into my file explorer I can see the TB folder and all of the .zip files for each app. I have put the folder on my SD and on my Internal memory and still nothing showes up to restore. PLEASE PLEASE HELP I can not find anything on my issue and don't know where to go from here. Thanks in advance!

I expect you just need to go into TB's settings/preferences and set the folder to where your backups are.
