The EFS location has no data at all. With it having no data, I get a black semi-transparent box that pops up with yellow lettering in it. Is there a way to restore this EFS Data? No I didn't make a back up.
I am on 4.3. WIth out the EFS data, you aren't suppose to have your IMEI data or soemthing, but my IMEI number is in my about phone information and my sorta works fine.
Here is what I have done to try and fix this issue
Reflash with odin
reflash with keis
factory reset through operating system
factory reset through recovery
reflash with odin using pit file as well
