Efs Folder Lost


Oct 10, 2017
Hi guys,

I bought a Redmi 3 Pro that didn't turn on. I flashed a ROM and it worked, but the smartphone doesn't have the EFS folder and so doesn't recognize the SIM card and I can't either register my Xiaomi account to unlock the bootloader. I got to install TWRP and SuperSu without unlocking the bootloader but now I don't know how to create the EFS folder.

I insert a photo so that you can see that the folder is not there.

Sorry for my bad English.

Thank you very much.
