[Q] EFS Professional backup PROBLEM

I have been trying to backup the efs folder on Samsung galaxy Music GT-S6010 using EFS Professional v2.0.62 and when the software is "Extracting PIT from device for mapping ..." it shows "operation failed" and gives a prompt showing it was "Unable to extract PIT from device!".
I have attached a screenshot of the issue, anyone kindly help.

Similar problem on Galaxy S GT I9000, MORE DETAILS given
Hello,
I have a problem with EFS Professional. I searched the development thread (http://forum.xda-developers.com/showthread.php?t=1308546) and googled it as well. Although some solutions were offered my problem is not solved. I am not a complete newbie but not an expert either, so maybe I have a really simple issue here?
I am simply trying to backup the EFS partition on Samsung Galaxy S GT I9000.
The problem in short:
1. All seems to be well on welcome tab.
2. While running the backup, I get “Unable to read PIT file!” and the process stops.
3. If I run it again it skips the PIT file part saying “Skipped, already exists.” And then a popup shows saying “unable to create archive!”
4. Note: a tar.gz file is actually created and placed in a new EFSProBackup folder on the phone under /mnt/sdcard. The size of this file is only 29 Bytes and I think its basically an empty file).
Note that I did change my Busybox to version 1.20.0.git (but not 1.20.0 if it makes any difference?) as was suggested).
Can anyone help?
Please see a detailed description below.
Many thanks!

Efs backup
Try online Nandroid backup app. It will back up everything including the EFS folder.

Perfect!
It's so much simpler and works like a dream! I just hope it will work as promised if anything goes wrong while flashing a new ROM!
Many thanks for your reply!

[Q] Help needed to restore bricked/dead N9776 MT6577 phone

Hi XDA members,
Some help needed here to restore/revive my dead smartphone. Here's some information that I was able to get from MTKDroidTools before it went dead:
Hardware : MT6577
Model : e1911_v77_gq2000_a41_6628_v20
Build number : e1911_v77_gq2000_a41_6628_v20_20130424
Build date UTC : 20130424-072257
Android v : 4.1.1
Baseband v: MAUI.11AMD.W12.22.SP.V15.P2, 2012/12/24 13:28

I believe the phone is Ulefone / Star N9776 though the site that I purchased from stated it as Triton Pad 6": http://www.lightinthebox.com/i9977-mt6577-android-4-0-dual-card-quand-band-6-0-inch-cpacitive-touchscreen-cell-phone-wifi-fm-gps-3g_p520179.html
Here's the chronology of what I've done 'til the phone went dead:
- Rooted the phone using Kingo Android Root
- Added CMW Recovery using MTK Droid Tools (v2.4.5)
- Made a backup via MTK Droid Tools
- Tried to flash a LEWA ROM provided on http://forum.xda-developers.com/showthread.php?t=2260653 via SP Flash Tool (v3.1312), but can't get the phone to work (boot loop on Android animation)
- Tried to recover from backup created by MTK Droid Tools inside clockworkmod folder via CWMR, but got MD5 sum error
- Tried some more Star N9776 ROMs found on NeedROM site via SPFT, with no luck
Somewhere in this process, I've clicked on the Format Whole Flash without realizing what I was doing
- Phone completely bricked/dead! Unable to access CWM recovery mode, battery charging unrecognized.
Additional note, I still have the full backup that was created by MTK Droid Tools on my PC, about 2 GB in size. Tried to create blocks for SPFT but it gave errors. Here's the report:
The signature isn't found! ... File Size Too Small!

My last resort to resolve this problem which is to push up a stock ROM provided by yuweng (http://forum.xda-developers.com/showthread.php?p=37157380#post37157380) via SPFT gave me no luck either. I've always got this BROM 3004 error stating that my phone doesn't support DRAM
Help and assistance from experienced members is greatly needed, hopefully those who have a phone with similar specs to mine. Thanks!

have you tried a higher version of sp flash tool?

Tab 7.7 Restars every 5 minutes. Deleted data reappears after restart.

Dear All,
I am using Samsung Galaxy Tab 7.7 (GT-P6800) with the below Items :
Android Version : 4.1.2 (Jelly Bean)
Baseband Version : P6800DXMD3
Kerner Version : 3.0.31 - 1157844
[email protected] - 133 #3
SMP PREEMPT MON APR 22 22:19:00 KST 2013
Build Number : JZO54K.P6800DXMD3
EMMC Type : MAG2GA
CID : 1501004d4147324741076f07993b5f91
Revision : 0X7
The EMMC data has been extracted from gotbrickbug app.
Also I was using Framaroot 1.5.3 with the Aragorn exploit and was using gamehacker application and lucky patcher. Some days before I did framaroot exploit and forgot to unroot the device and kept the device idle for some time. After a while, my device got restarted automatically and after that it is working in weird fashion. Whatever I delete reappears and what ever i add is getting deleted once i restart my device. Also the device is restarting every 5 minutes once. I installed various applications to find whether my device got the EMMC Bug but most of the applications didn't gave any error. Then I looked into the MAG2GA Trim bug and it looks like I had got one as some of the mp3 files gets corrupted now and then for a while. So it looks like memory is getting corrupted for some or the other reason. I tried to flash Samsung Stock version of Jelly Bean and Honey Comb. Odin gave success message but no change happened. Looks like the EMMC is in read only mode. I tried SU and mounted my /system with read write mode and restarted the device. But nothing happened after that also. I tried factory reset / wipe data / wipe cache partition but nothing is working. Also in recovery mode I am getting a line in Red color : "did not match sized '/system/csc/common/system/cc/others.xml'(No data available)". I went to this path via su and found the file was present. I tried to install TWRP, CWM etc., but everything got erased once i restarted my device. Is there any way where I can get my tablet in working condition other than hardware change.
I tried installing cyanogenmod through sdcard from recovery mode but I am getting difference in signature as I am not able to install CWM / TWRP to change that.
Hoping for a valuable feedback.
Regards,
bhaarn.

This is stock ROM for Galaxy Fit GT-S5670. I want to make sure I can correctly backup my IMEI and the EFS data before pushing modified ROM image to the device. I used mobogenie to do initial push of .apk files for rooting, and also ran the Mobogenie ROOT tool.
On EFS Pro (Beta) (couldn't find a stable OLDER version...I would like to try an old one.) I go to the Backup Tab, and under device filters I don't see my version of Samsung Galaxy FIT In the Manage section of device filters. Anytime I try to do anything with the Device Partitions or Device Filters I get the message: Number was less than the array's lower bound in the first dimension. Parameter name: srcindex
Please advise me if this is just a dumb question of a newbie?

How To Guide [Tutorial] Recover from IMEI or GPS not working due to corruption (restoring efs and sec_efs)

I was trying to enable the privacy wifi feature that changes the MAC address of the wifi adapter on every connection (see https://github.com/phhusson/vendor_hardware_overlay/pull/610 as an alternative to https://github.com/Magisk-Modules-Alt-Repo/MacRandomizationEnabler).
While doing this, I encountered an issue that all of a sudden, the phone would not connect to cellular (IMEIs were gone) and GPS would not work anymore. This is quite frustrating and could essentially render your phone unusable with respect to its main functionality.
I was not aware of the fact an efs backup is required. However, I had backed up efs and sec_efs right after the problem.
I also found that the problem could occur just due to the use of Magisk (after some weeks).
The public documentation on efs in general is already sparse, but the one for the Exynos based models is close to non-existent from what I found. That's why I thought I would share my journey and findings.
This is how I went ahead to restore the functionality. In particular, due to the Exynos chip, things are different to other tutorials which either rely on MediaTek or Qualcomm chipsets, which store the NVRAM (responsible for IMEI, ...) in a different way (not in Samsungs own encrypted and obfuscated .bin format) and have more accessible ways of setting IMEI (via serial console, external tools, ...). There, the restore process is different.
Prerequisites
Backup (potentially corrupted) of efs and sec_efs
TWRP
How to proceed
Code:
- Remove any root app that might infringe with the "efs" data, such as MAC address changers, ...
- Restore both "efs" and "sec_efs" partitions with TWRP (with no intermediate reboot)
In my case, the most recent "nv_data.bin" inside the "efs" backup was corrupt (as I backed it up AFTER the corruption), so I needed to continue as follows
Code:
- Do not reboot to system directly after restore
- In TWRP, reboot to "fastboot" and enter ADB
- Run "adb shell"
- cd /mnt
- mkdir test
- mount /dev/block/by-name/efs test
- cd test
- ls -al
in addition to "nv.log" (just a log file), "nv_data.bin", "nv_data.bin.md5" (the corrupted ones), ensure there is also ".nv_data.bak", ".nv_data.bak.md5" (the timestamps of which were in the future, but that's ok)
- mv nv_data.bin nv_data_corrupt.bin
- mv nv_data.bin.md5 nv_data_corrupt.bin.md5
this will cause "nv_data.bin" and "nv_data.bin.md5" to be restored from the ".nv_data.bak", ".nv_data.bak.md5" files on the next reboot, observe this later in the "nv.log" by the following lines
[none]DATE:Not exist secure efs
[none]DATE:Nv restored 3
- cd ..
- umount test
- rmdir test
- Turn the phone FULLY off
- Reboot
- Cellular connectivity and GPS should be working again!
- Make an immediate backup of "efs" and "sec_efs"
In theory, you should also backup "persist", but I didn't find a corresponding partition.
- (Optional) Remove the corrupt ".bin" and ".bin.md5" files in "efs"
I hope this gives some insights on nv_data on Exynos chips and potentially helps anybody in a similar situation.
