Editing partition image
My Samsung phone lost its IMEI number. As far as i know it stored in /efs/sec_efs/SVC és !SVC files.
These files cannot be edited during running. My idea is that i "dd"-ed the efs partition to an image file, then i would edit these two text files, then restore the efs partition from the image with ODIN (It's similar to fastboot mode on other brands).
How can i edit the partition image file?
- I wanted to mount the image file on the phone with ADB as a normal writeable partition, then edit the SVC files. But how can i mount it?
- Mount the image file on Windows like CD/DVD/etc image files, then edit the text files. But how can i mount or edit the image file? Is there a working application for this?
- There are lots of IMEI editor apps, but i can not trust these random apps from the net.
- Any other idea to restore the IMEI?
(I know it's illegal to change IMEI. I don't want to change it, i want to restore the factory assigned IMEI.)
