NV restore doesn't work: I created a backup of signle 6828 nv-item, modified backup txt-file, and as program sez succesfully restored it back. But when i make another backup (to be sure, the modification is applied) - is is as it were before, with no modification. So, the program doesn't write nv data?

p.s. galaxy note p607t
[Galaxy S II Original Android Development] lyriquidperfection:
It does write nv data but only if the item you are writing is not security protected or read only.
[Galaxy S II Original Android Development] m4D2016:
so, it's impossible to overwrite this data, even with qxdm/qrct?
[Galaxy S II Original Android Development] lyriquidperfection:
Yes as you need to be in a special boot mode to allow access to protected nvm values

wont work at all

keeps telling me that busybox is not installed even though I have it installed, there are no version numbers in the error message. yes I do have root as well
[Galaxy S II Original Android Development] CarteNoir:
I keep getting the following error when it gets to the Creating Archive part at the end of the Backup of my EFS:

tmp-mksh: tar: not found

exitcode=127

Any ideas?

EDIT: Fixed it by making sure BusyBox was installed to /system/bin (it was installed to /system/xbin before) and by making sure the phone screen was on and unlocked while the backup was taking place.

can we repair lost imei with this tool?
[Galaxy S II Original Android Development] CrashOverride93:
Sorry, one question. EFS Pro woks with LG devices?

- Specific: LG K10

And another question: if I select to backup all partitions option, it will make a backup like a nandroid backup on a custom recovery? or a nandroid backup is different from what EFS Pro can make with backuing up all partitions?

I have got lg backup using your tool with EPB. I have unfortunately hard brick it and I was wondering if I convert them to IMG or BIN ? Or is it simply a rename ?

Could not find via search

Thx

very good i can give system backup galaxy j1 SM-100J1ML/DS
[Galaxy S II Original Android Development] lyriquidperfection:
any EPB files are simply whole partition blocks including free space. Normally you could just dd them back to your device if you know the partition locations but in your case of hard brick then this will not be possible without jtag.

Okay guys apologies I have been away for a long time, I dont get much time for hobbies these days as my youngest daughter who is 10 months old was recently diagnosed with a mass on the front of her brain which is causing secondary Epilepsy resulting in seizures so me and my better half have had our hands full looking after her along with our eldest daughter who is 3.

I wanted to show you an update of Qualcomm NV Tools which I have now made a standalone application.

Please click here to jump straight to the Qualcomm NV Tools thread.

There is no download available yet but I am updating as and where I can due to the very limited free time I have available as I also work full time too but its shaping up nicely.

Please take a look at the screenshots and leave your comments in the Qualcomm NV Tools thread and ill reply when I can.

Just want to take the opportinity to thank everyone who has supported me over the years and downloaded EFS Professional. There have been over a million downloads globally through multiple sources so thats just WOW! :)

Your family is in my thoughts man : ) I'm so sorry for what your daughter, your wife and you are facing! For what it's worth, though I've never had to use your program (thankfully I guess), the fact that you've such a firm grasp on such extremely complex subject matter makes it clear that you're brilliant on top of being an awesome dad.

Your family and your daughter is in my thoughts.

Also a good work, by the way.

Is this tool up to date for being used for my Galaxy s5 neo (SM-G903F) ?

It is on the latest Stock Firmware (No Branding Android 6.0)
[Galaxy S II Original Android Development] lyriquidperfection:
Hi yes it should be. You can test by selecting one partition to backup and then try restoring afterwards. I have noticed people having issues with backup and restore as the backup can't be saved to internal storage for example. You must ensure all relevant permissions are enabled on your device and that busybox is installed. If issues persist then it's probably due to changes in a newer busybox version so it's recommended to use the version EFS Professional states for compatibility and thank you for your kind words. :)

"unable to extract Pit from Device"

Any help?
[Galaxy S II Original Android Development] lyriquidperfection:
What device do you have? Usually this only happens if your Samsung device uses a different way of identifying partitions like on some older devices.
[Galaxy S II Original Android Development] farroo:
Its Samsung galaxy note 4 SM-N910S ( SK Telecom ) stock based 5.1.1 ROM. I somehow currepted the IMEI. It does not show IMEI by dialing *#06#( displays 000). Baseband version is correct.
[Galaxy S II Original Android Development] Prodean:
I've made a backup of the EFS using this program last month. Since my SII wasn't found in the device list, I decided to backup the partition named efs on /dev/block/mmcblk0p4 , and I thought I was safe.

Today, my EFS got corrupted and I tried to restore the backup. It was successful, however upon rebooting the device I was still getting baseband, IMEI, IMEI SV unknown. I tried to format the EFS folder, and restore the backup that I've made but it wasn't successful. I also tried the repair NV Data permission option.

Can anyone help me on this? I'm thinking that my backup wasn't sufficient, hopefully that isn't the case :fingers-crossed:
[Galaxy S II Original Android Development] bumperbee:

[Galaxy S II Original Android Development] holistone:
I am able to write the IMEI on my Sprint LG G3 LS990 using the NV tools Secure Ops tab since I have the SPC code, but I am unable to write ESN or MEID which return "Error: NV_ERR_READ_ONLY_NV_ITEM". The IMEI alone is not enough to allow activation (which presumably also check ESN and/or MEID).

[Galaxy S II Original Android Development] holistone:
The video shows how to change the IMEI on a G2. There are easier ways to alter the IMEI, such as the free EFS Professional (which does the conversion for you). The problem is that correcting the IMEI is not sufficient to allow activation. Apparently the phone sends the MEID to the tower (not the IMEI). For the G3 the ESN (NV item 000000) and MEID (NV item 001943) are read only and I have found no free tool that can change them. In my case, the ESN, MEID, and IMEI were all corrupted. If anyone has any suggestions (some other password? or different driver? or software? or special phone mode?) for restoring the ESN and MEID NV values they would be greatly appreciated.

I am not trying to clone a different phone or switch carriers. I am trying to restore the ESN/MEID/IMEI to the values on the sticker under the battery.

Hello everyone,

I have a Samsung Galaxy S2 i9100 and I'm trying to install Lineage OS 7.1. The flashing goes smoothly but when it reboots, I type the SIM's pin and I get the "SIM operation failed" message. I remember I messed around with the efs folder some years ago but after that I have been able to flash several ROMs, CM 12.1 for instance. I tried to flash CM 13 but I did ran into the same problem, I couldn't go beyond the SIM's pin screen.

I'm trying to use EFS Professional but in the Device Filters menu there's no Galaxy SII and no matter what device I choose, the Device Partition window stays blank. I can not do anything with it.

The current IMEI in my phone right now is 004999xxxxxxxxx. How can I reset it to the right one? I'm desperate!

Thanks for your time!

This is my problem: even having made the backup with EFS Professional 2.1.80 Beta, when I load it to restore, the partitions won't show.

Is there anything I could do to restore my partitions?
[Galaxy S II Original Android Development] jmo707:
I don't know... I've used *All partitions* because my exact model won't appear neither. Yours won't show anything to backup? Or you are talking about restoring?

Hello,

I was on the latest version of LineageOS on my GT-I9305.

This weekend I have tried to create an invite profile, normally, through the Android profile interface.

Doing this has destroyed my network access : Now, I cannot receive SMS and I cannot make a call... =/

1. Is it a known problem ?

The phone ask me a "network unlocking code". I have tried to understand what happens and I think my /efs partition is corrupted and I have no backup of this partition.

I still can see my IMEI in Android but I don't have the /efs/nv_data.bin file. I think the invite profile creation has deleted it.

2. Can you help me ? How can I do for restoring my phone call and SMS ?

3. Just to be sure it's normal : do you have the file /efs/nv_data.bin in you efs folder ?

For now I have tried to come back in an official Android 4.4.4 Samsung ROM, but the problem is still here.

However, I can now use the Qualcomm NV Tools from here https://xdaforums.com/galaxy-s2/orig-development/tool-updated-09-06-14-efs-professional-t1308546, but I don't know what to do.

I can read in Secure Ops. :

ESN : 0

MEID : 0

IMEI : (my IMEI)

4. Is everything normal ? Can I recreate here the lost nv_data.bin ?

Thanks in advance for your help.

Great tool! It has never failed me, well, until now. I'm trying to back up EFS on a Galaxy S5 (SM-G900F) running 6.0.1 Marshmallow, but it can't give up on corrupting the backup. No combination of the backup options helps prevent the borkage. I can work around it by backing up an additional partition with a label that starts with any letter coming after n or, to be precise, alphabetically coming after nvrebuild2.bin, but that seriously ruins the impression of reliability of EFS Professional and the backup itself.

In the beginning it was also unable to extract the PIT file, but that problem magically vanished after I manually dumped the PIT file and did a few reboots (both PC and phone) in between. Also, it would be really nice if the file names were generated with timestamps containing leading zeros, as files otherwise end up sorted strangely.

Please correct me if I'm wrong, but to me it seems like you installed the BusyBox application, but did not install BusyBox itself. To do the second part, you need to fire up that application and install BusyBox from there. Installing BusyBox requires superuser privileges, so make sure your SM-G950F is rooted before that.
