WARNING! DO NOT FLASH YOUR DEVICE UNTIL YOU HAVE BACKED UP YOUR IMEI / NV DATA IN THIS GUIDE!


Click HERE for information on the long awaited and all new EFS Professional v2.0 including download! Now supporting Qualcomm devices!



Setting up QPST with your PC:
  • Dial *#7284# on your phone to access PhoneUtil and select 'Qualcomm USB Settings' at the bottom. Now select 'RNDIS + DM + MODEM' and press 'OK' to return to the previous screen. Now press your 'Back' key to exit PhoneUtil. Your phone is now in DIAG Mode.
  • Download and Install: SAMSUNG_USB_Driver_for_Mobile_Phones_1590.exe - 23.06 MB if you don't already have Kies or a USB Driver installed.
  • Download and Install: QPST v2.7.378.zip - 14.68 MB
  • Now connect your phone to the PC with a USB cable and wait for Drivers to install.
  • Start the 'QPST Configuration' application and select the 'Ports' tab then press the 'Add New Port...' button.
  • Select the COM Port that has 'USB/QC Diagnostic' next to it, change the Port Label if you like to 'Samsung GT-I9305' then press 'OK'.
  • You should now see your phone listed in the 'Ports' tab and the 'State' should indicate 'Enabled'.
  • You can now Close this application.


Backing Up IMEI / NV Data:
  • Start the 'Software Download' application and select the 'Backup' tab.
  • Press the 'Browse' button and choose a Save Location for your QCN File.
  • Press the 'Start' button and wait for it to finish. This will back up all your phones NV Items and save them to the QCN Backup File.
  • The resulting QCN Backup File should be 250KB.


Restoring IMEI / NV Data:
  • Start the 'Software Download' application and select the 'Restore' tab.
  • Press the 'Browse' button and select your QCN Backup File.
  • Press the 'Start' button and wait for it to finish. This will restore all your phones NV Items from the QCN Backup File.
  • Your IMEI / NV Data should now be fully restored. Dial *#06# on your phones keypad to check your IMEI is restored.


Restore USB Settings after Backup / Restore:
  • Dial *#7284# on your phone to access PhoneUtil and select 'Qualcomm USB Settings' at the bottom. Now select 'MTP + ADB' and press 'OK' to return to the previous screen. Now press your 'Back' key to exit PhoneUtil. Your phone is now back to default USB operation.
Quote:

If the 'Qualcomm USB Settings' Button is missing from the PhoneUtil application then execute the following command in a Terminal Emulator to launch the Qualcomm USB Settings page directly:

su -c 'am start -n com.sec.android.app.phoneutil/com.sec.android.app.phoneutil.USBSettings'

Please Note: You must be rooted or this command will not work.


Recovering IMEI And Data Connection After Flashing WRONG Root Package Intended For I9300:
  • Make sure you have Samsung Kies or the Samsung USB Driver installed on your PC.
  • Download and Extract: Odin3 3.04.zip - 457.11 KB to your PC if you don't already have it.
  • Download and Extract: Param_Bin_I9305.zip - 612.14 KB to your PC.
  • With your Phone Switched Off, press and hold: 'VOL DN' + 'HOME' + 'POWER' to enter Download Mode.
  • Connect your phone to your PC via USB Cable and start Odin.
  • Check your phone is connected by seeing if a COM Port in a Blue box is present under ID:COM.
  • Press the 'PDA' Button and select the 'Param_Bin_I9305.tar.md5' file you extracted from the Zip Archive earlier.
  • Press the 'Start' Button and wait for it to finish flashing. If successful, you will see a Green Box with 'PASS!'.
  • Wait for your phone to reboot then go to your Dialer and press: *#06#. You should now see your IMEI and your Data Connection will be back.

If I have saved your bacon then please buy me a coffee!

well i guess this is what i'm going to be looking for.

So i have no IMEI on me device and I have no backup of the EFS.

Before I pm you:
1) do I need to have a rooted device to perform this? if so I can install your pre-rooted ROM.
2) when i go to *#7284# menu I see the following screen.
PhoneUtil

UART
[option(selected)] MODEM
[option] PDA
USB
[option] MODEM
[option(selected)] PDA
SAVE and RESET

so i have no "RNDIS + DM + MODEM" option, can this still work for me?

thanks

phew, was about to dive into flashing and then saw this thread. THANK YOU!

I am an iOS refugee. Totally new to android. I guess I'll wait for more developments to come out for my Quad core LTE S3.

There is a 'Qualcomm USB Settings' button at the bottom of the screen in PhoneUtil. Press that and you will be able to select "RNDIS + DM + MODEM".

Nope, still dont have that option.

Tried with/without USB connected
with/without usb debugging
with without SIM card inserted

but all these methods still result in the screen i described above.
Do I need root?

else, i guess i'm well and truly screwed.

No you don't need Root and just to confirm you do have the I9305 don't you?

I have the UK EE I9305 and when I dial *#7285# I have the 'Qualcomm USB Settings' Button at the bottom of the screen on PhoneUtil.

Yes, I also have UK EE i9305, purchased from t-mobile.

Would be interesting to see if the others who have lost their imei have also lost this option in the phoneutil menu. failing this, i really need to be able to reset the flash counter and have the status to "Normal" before i consider sending it back.

Yeah! Would be interesting to know that as if the 'Qualcomm USB Settings' button is missing then the whole process is pointless unless there is another way of invoking 'DIS + DM + MODEM'

@lyriquidperfection, many thanks for this, have made a backup just in case!

Don't worry there is a workaround, just need to do more testing before I release it. It is basically a set of commands originally for AOSP Roms which I modified specifically for the I9305 to manually Enable or Disable the Diag Mode. So this Backup and Restore method will work for everybody.

when I try to dial #7284# or #7285# I get this message. I haven't flashed yet so everything is still pretty much Virgin. Can any one shed a light on this?
