Need Help Repair Boot Samsung I747

[xKxOxDx]

Hi I need a little help from a customer brought a computer to update the Samsung I747 with the following firmware:

I747_ATT_I747UCUEMJB_I747ATTUEMJB_Original

Try to repair it with Medusa and RIFF but these repaired successfully and the computer still bricked, so I decided to do it with ATF, but I need the process and the files needed to recover.

I need to write the bootloader file.
or please show me how to extract the tar file and pass it in the BOOT PARTITION, if I write in the USER AREA or boot1 or boot2, since I've tried everything with this team.
