I'm trying to put the factory mode in user mode.

I have a s3 schi535 with android 4.3 and efsv2.

In samsung tools try to do but it gives me error.

I guess the problem is because the program does not detect the partition efsv2, I'm right?

Help me please.

[Galaxy S II Original Android Development] lyriquidperfection:
If it cant detect efs location then its not mounted and therefore cant make any changes.
[Galaxy S II Original Android Development] xmae:
This is the error..

I need to put the phone in user mode :(
[Galaxy S II Original Android Development] lyriquidperfection:
Yeah you need to mount the efs partition to the /efs folder to see if its still intact before you can do anything else.

EFS stopped recognizing phone is connected

Hello,

lyriquidperfection, before asking, I just wanted to complement you on creating EFS professional, it's a great piece of program.

I recently bought GT-I9300, flashed to CM 10.2, during flashing efs was damaged, IMEI changed to default. The backup I had is corrupted.

Flashing back to stock didn't help to restore IMEI. Tried also other options from this forum. Also tried to format efs, EFS couldn't unmount the partition.

One method suggested to change USB settings to RMNET + DM + MODEM (I can't post links in the forum yet) by entering a specific menu (*#7284#). Since I couldn't get to this option (*#7284# showed other options), I changed it using EFS professional.

Unfortunately, it didn't solve the IMEI issue and now EFS can't detect the phone (state it's not connected). Also, *#7284# doesn't work at all (won't even give the previous options). Is there a way to restore USB settings to default so EFS will recognize the phone? (tried flashing to stock, didn't work).

Thanks you!
[Galaxy S II Original Android Development] lyriquidperfection:
Try *#0808# to change usb mode.
[Galaxy S II Original Android Development] aloter:
Nope, doesn't work. *#9090# does work, but I'm not sure if it's related to this.

Also wiped data and cache from recovery, didn't do much.

Thanks for the fast reply!
[Galaxy S II Original Android Development] lyriquidperfection:
Ahhh change your usb mode in settings back to mtp and it will reset it and make sure usb debugging is enabled.
[Galaxy S II Original Android Development] aloter:
Great, it's working (I returned to factory settings, rooted, installed busy box and enabled debugging), thank you!

Returning to original issue, is there a way to rebuild efs to restore IMEI? formatting it fails (in unmounting stage. "failed: Device or resource busy")
[Galaxy S II Original Android Development] lyriquidperfection:
If you dont have a backup then you would need a box to do an efs rebuild to repair signal and imei.
[Galaxy S II Original Android Development] KrissSo:
Backup ok, but Restore cannot find backups?

Hi liquidperfection,

Thank for the app and for your time spent on it.

With efspro 2.1.73, I can make backups but cannot see them in the restore's combobox.

I've a S3 4G (Int Lte), I successfully made a backup, but there it doens't appear on the restore view, even after clicking on the refresh button. I can see the tar-gz file in EFSProBackup dir in both PC and the phone (on default location, ie /sdcard). I can even get them from phone using an adb pull. The backup log showed everything went fine... I restarted the app, re-made a backup. Still nothing visible in restore.

Any advice?

Thks a lot
[Galaxy S II Original Android Development] lyriquidperfection:
Hmmm thought I had ironed out this little bug! What busybox version are you using?
[Galaxy S II Original Android Development] KrissSo:
1.21.1. Could it be too old? (I'm trying an old 4.3 rom)
[Galaxy S II Original Android Development] lyriquidperfection:
Try with the latest busybox and see if that makes a difference.
[Galaxy S II Original Android Development] KrissSo:
No change when simply updating busybox.

Edit: I updated the rom to a newer version, including new kernel (The Galaxy Project v18.02 base XXUENE4), and restore now works. So let's say it's solved. Thank you.

AT&T Galaxy Note 3 SM-900A KitKat 4.4.2

I'd like to switch my IMEI off of a broken note 3 with bad motherboard, to a working note 3 with a BAD IMEI. Can I use EFS Pro to fix my IMEI and rewrite the Good IMEI from the broken phone to the phone with the BAD IMEI? What is the process for doing this? Your help will be greatly appreciated!

Please don't ask for advice on how to do something illegal here on XDA. There are plenty of shady websites and forums with the information you want. Don't be lazy
[Galaxy S II Original Android Development] DoctorQMM:
Hello. does the EFS Pro tool support the I317 Samsung Galaxy Note 2 (AT&T) device? Looks like it supports all the other Samsung devices, but couldn't specifically find the I317 Samsung Galaxy Note 2. Thx
[Galaxy S II Original Android Development] lyriquidperfection:
Yeah its supported, just not all device filters are listed. You can easily make your own.

my device is samsung galaxy discover
[Galaxy S II Original Android Development] aplsux:
Would anybobdy know why when I try to connect my phone with the program, there is nothing in the "Available COM Ports" dropdown?

Is it because I don't have serial ports? I have two USB 3.0, can't I use them instead?
[Galaxy S II Original Android Development] lyriquidperfection:
Your phone needs to be in diag mode for the serial ports to become visible.
[Galaxy S II Original Android Development] aplsux:
Hi, thank you for your help.

I think I am putting the phone in diag mode, everything checks out, except for the fact I get no COM ports. After the final "setprop sys.usb.config diag,adb" command, nothing happens. I thought the computer would start the COM port installation, but nothing.

Why I can't connect with EFS tool?

It was "Device not connected" even I turn on USB Debugging mode in my phone, plugged in the 2.0 USB port of my lap by a good cable :(

Nothing, :(

Apparently, being EFSv2 not work,???

[Galaxy S II Original Android Development] lyriquidperfection:
I think mmcblk0p19 is the partition where your efs resides. Like I already said previously, you need to mount it to your efs folder.

From a terminal type:

su

mount -o remount,rw -t ext4 /dev/block/mmcblk0p19 /efs

You should now have your efs mounted.
[Galaxy S II Original Android Development] xmae:
I tried from the terminal of the smartphone and from adb in windows and this is the result in both

Not recognized as a command mount

root@d2vzw:/ # mount -o remount,rw -t ext4 /dev/block/mmcblk0p19 /efs

mount -o remount,rw -t ext4 /dev/block/mmcblk0p19 /efs

[Q] SGH-I717(Note 1) Compatability

Any suggestions for getting this to work with the SGH-I717(Note 1)? I've been trying for a few days and can't figure it out.

Is it not supposed to work with the I717? When doing a manual search I notice that I seem not to have the NV_DATA files.

Any advice would be appreciated. Either way, take care folks!
[Galaxy S II Original Android Development] lyriquidperfection:
You wont have nv_data files as its a qualcomm device. The nv area is stored across the modemst1 and modemst2 partitions. You should use Qualcomm NV Tools and communicate with your device in Diag mode.
[Galaxy S II Original Android Development] Matholameu:
That was quick!

Thank you for prompt reply. I made sure to press the 'thanks' button.

[EDIT]

Well I've been playing around with Qualcomm NV Tools and it can't seem to read anything off my phone.

It says it's connected, however no info pops up. I might just be doing something wrong though.
[Galaxy S II Original Android Development] Matholameu:
My note seems to be unable to use dialogue mode. I have no Qualcomm USB Options. Also I still can't get QNVTools to read any data off my phone. Is the program known to work with the SGH-I717?

EFS Pro 1.3.2 has now been released.

Please post your feedback about any application hangs or freezing.

Enjoy! :)
[Galaxy S II Original Android Development] Azure1203:
Still freezing for me. Galaxy S Fascinate 3G+ running DarkyROM 2.3.6

I want to update to a ICS ROM, but I want to backup my EFS first. If I open the program again after it freezes, it says it has a backup to use. Can I trust that?

It goes to 'cleaning temporary files' and then hangs.
[Galaxy S II Original Android Development] lyriquidperfection:
Hi what version of busybox does your phone use?
[Galaxy S II Original Android Development] bartje885:
Thanks, but I still can't connect my ICS based ROM to the computer to backup with EFS Pro. What could it be?

[Galaxy S II Original Android Development] lyriquidperfection:
Do you have Samsung Kies software installed on your PC?
[Galaxy S II Original Android Development] bartje885:
Yes I do, do I need to uninstall it? I killed all processes with KIES in it. And I checked the USB Debugging option.
[Galaxy S II Original Android Development] lyriquidperfection:
No thats fine. Have you looked in device manager on your pc to see of usb drivers are installed correctly and phone is detected?
[Galaxy S II Original Android Development] bartje885:
I did this morning, Windows Update had a update for ADB driver and I installed it.

This is a picture of the device manager: http://d.pr/8ZtO
[Galaxy S II Original Android Development] lyriquidperfection:
Everything seems to be connected fine. Does EFS Pro hang or freeze when you backup to an image file (*.img) or is it when you try to backup to a Tar archive?
[Galaxy S II Original Android Development] bartje885:
The program doesn't start up. See the next two images:

First

Second
[Galaxy S II Original Android Development] lyriquidperfection:
The first image, this dialog is always displayed as a reminder. The second image. Ill have a look at the device detection routine and see where I can improve the code.
[Galaxy S II Original Android Development] bartje885:
Did you test ICS based ROMS? Did you successfully connect a ICS devices yourself? Maybe that's the problem. I can try to revert back to GB and try to make a backup
[Galaxy S II Original Android Development] lyriquidperfection:
I have not tested ICS Roms yet but figured as they also use the adb interface, they should work fine. I will have to install an ICS rom and do some further testing.
[Galaxy S II Original Android Development] bartje885:
Okay thanks! Meanwhile I will try a GB ROM
[Galaxy S II Original Android Development] bartje885:
Reverted back to GB 2.3.6 stock with Root access and it worked. So the problem is in ICS.
[Galaxy S II Original Android Development] gadget069:
Worked fine for me too.
[Galaxy S II Original Android Development] syserr:
EFS Professional feels very professional! ;)

I've been trying to move programming information into my SCH-R530X (S3 Generic CDMA) from a donor phone. The SCH-R530X comes from a regional CDMA provider, but I've moved it (part way) to PagePlus. Voice and SMS work, but not data.

It seems copying the values from the donor phone to the SCH-R530X by use of DFS is not enough. (I've been successful going to PagePlus with a few Verizon 4G and one Sprint Note3, so I'm not a total noob) This tool is interesting in that it says it can format EFS and restore (selectively?) EFS. Is this what I need to do? It seems the regional CDMA provider has tweaked something in this S3 that I can't un-tweak with DFS.

I'm grasping at straws. I'm doing this for my dad (70), first experience with a smartphone and paid $500 for it in February. I have not tripped KNOX and have not tried to root yet -- a bit scared as receiving audio during calls is weird and might want to go back to the factory.

Please help.

Restore of NV Item does not work for me

Hi,

I'm using the Qualcomm NV Tools (sub-program). It works great to make backups of the NV Items to a text file. But I'm having trouble restoring. For example... I go to NV Items Range and I set dec range From 906 and to 906. I click Backup NV Items button and save it to a file. I go edit some hex values in this file. Then I click Restore NV Items. I read the value back with Backup NV Items and my edit had no effect, so I think it is not actually restoring.

Can anyone confirm this? Is it a known bug?

Thanks!
[Galaxy S II Original Android Development] lyriquidperfection:
This means the particular nv item you are trying to change is read only. You are right there is a bug but only because efs pro doesn't tell you the NV item is read only. I've already corrected this for the next release. You would need your device in factory mode and connected via UART cable to change read only nv items.
[Galaxy S II Original Android Development] banziitox24:
How I can put my device in factory mode
[Galaxy S II Original Android Development] lyriquidperfection:
I just said above, you need to connect your device via a UART cable then power on, it will boot into factory mode.
[Galaxy S II Original Android Development] banziitox24:
Oh alright I thought it was the other factory mode(FT Mode), after connecting via UART I can write on any Read Only NV items? And what about the SPC? I will be all zeros right
[Galaxy S II Original Android Development] syserr:
Sorry, I forgot to say that I was able to change the NV Item in DFS in the NV tab. It kind of a mini Hex editor but not that easy to put many values in. I'd really rather use your tool. I keep wondering if it's operator error, so I posted exactly what I try to do in the previous message. Thanks for your work! Great tool other than my problem.

EFS Pro can't connect to my galaxy grand 2 running kitkat.

Hello Lyriquidperfection, I so love this software of yours, though I've not achieved my aim with it yet, but it sure has a lot of potential to solve serious technical issues for especially samsung device owners.

I have a Galaxy Grand 2 duos SM-G7102 with stock android JB 4.3, but upgraded to 4.4 KitKat. When it was running JB, the phone could connect to your software with no issues in RMNET+DM+MODEM mode. But after upgrading to KitKat, My phone can't connect successfully to your software anymore. Will your next update have support for KitKat? Also it will be well appreciated if we can alter the read-only values of the NV-items with your next update. Then again, please, the UART cable you spoke about. Is the connection between phone and PC? Or is it between the phone and some kind of box like z3x or Octoplus?

With stock JB, I could at least backup my NV-items, but with KitKat, phone cannot connect. So no hope of any more backups. For the record, my phone is rooted with clockworkmode based recovery.

Hi, I've tried searching this excellent thread.

My question is related to the radio.img and the LTE frequencies/bands.

Is it the nv in the hardware that dictates which bands are activated and all radio.img interact with all applicable frequencies or

are the radios (radio.img) somehow constrained to the region they're intended for

i..e those for Asia miss the all important band 20/ 800mhz LTE for Europe?

Thanks in advance for your help
[Galaxy S II Original Android Development] lalec:
I think radio.img handles only the GSM radio and LTE is in a different file.
[Galaxy S II Original Android Development] goRt:
Sorry but I understand the radio file name is split into 2 parts, the first part ending in g indicates the gsm version, the second part ending in l indicating the LTE version.

Are you able to reference your understanding?
[Galaxy S II Original Android Development] lalec:
I didn't see what kind of phone you are using but for example, on the Galaxy S4, LTE is in the file called "non-hlos.bin." I've seen this documented in several places but one example is here:

http://xdaforums.com/showthread.php?t=2678774
[Galaxy S II Original Android Development] goRt:
Thanks for that, 27 pages of rubbish.

To recap HTC m8 gpe emea (Europe, middle east and Africa), radio.img flashing via zip in twrp.

Does flashing a radio from Asia lose the 800mhz LTE band or is that controlled by the NV as adjusted in this thread?

I was able to make a backup of my SPH-L720 with EFS Pro. Nice software!

Then I used the Qualcomm NV Tools to backup the 1192 item. The resulting text file contains no actual value, just access denied message.

My question is: if I cannot read this item with the Qualcomm NV Tool, will the full backup be incomplete also? That is, should I need to perform a full or partial restore including item 1192, will item 1192 be null or incorrect after I restore?

Will downgrading to a different modem allow a proper backup? My baseband is MK2.
[Galaxy S II Original Android Development] IchHabDickeEier:
can somebody tell me which boxes i have to check for the complete baseband backup? I want to flash a new one in order to fix a bug in cm 11 but first i want to backup mine. Is efs enough or do I have to check other things too?
