The backed up EFS file is saved to the following location Storage/ extSDCard/ Samsung Tools. We tested the tool on Samsung Galaxy S4 and Note 3 and it worked fine. Besides, Samsung Tool also works as a reboot manager app. It lets you reboot your Samsung device into Download and Recovery modes without pressing the hardware keys.
My full code:dd if=/dev/block/mmcblk0 of=/sdcard/efs.img bs=4096Now when I pressed enter, the cursor went to the next line, I assumed the file has been saved and closed the emulator.Then I opened file manager, I found the file efs.img but the file size is 225mb!In one of the photos in this post(Backup using CWM/TWRP) the EFS size is only 9 mb!Did I do anything wrong?Also what is the difference between sdcard and External sd?
Not sure which directory it is in but when I open my root browser, I can directly see the efs folder along with cache, config, dev, mnt, root folders etc. Yes I do have but these tar files are the one which I backed up after I lost my network using EFS Pro, so not sure if they are of any use. I am attaching screenshots of EFS folder to see if that helps

i flashed back to the stock rom using odin and the baseband is normal once again but the imei is fake and root access is gone although efs back up in the form of tar file is still presentone more thing apart from making a back up i had also copied the efs folder in one of my separate folder which is still present.what to do next?
so you mean to say i must root my s3 again and then use EFS PRO,in that case few questions1) do i have to select the previous backed up file on my pc or device(both tar files)2) is format efs required and repair nv from internal and check sum need to be checked before format or along with it?these are few irritating questions i know but plz help
5) after format efs was successful i chose the file for restoration which in the drop down menu gave only the previously backed up efs file(via EFS PRO only in .tar format) in device(earlier i had tried restoring through the file saved in my pc but no results) and then hit start and viola it was done phone rebooted and i got imeri back and started working. 2b1af7f3a8
