[Q] efs and IMEI
Hello guys. I have a question, I tried a lot of different methods to backup the efs folder: used kTool tryed Philz recovery and many more. But I'm not sure if they really made a working backup.
First the ktool when I pressed backup and it finished it sad it was successful but when it ask to check if it's ok at the and it sad that "nv_data.bin NOT FOUND in backup !!!"
Second Philz recovery sad the same successful backup but when I tried to check the files on my pc the .img is a broken file, can't open it withe winrar.
The same is happening with every backuper. When I try to opened them they are all broken.
So my question is that should thees be broken or what ?
