You did the right procedure, but used the wrong file, based on your VAGUE description of 'R6BC002 in the first line then rolling down i see the same R8BE001' ... R6BC002 and R8BE001 don't just appear without other information. R6BC002 for what? R8BE001 for what?
Your log did not contain enough information to tell us that you did everything correctly.
If the phone is working fine for you, that's good. Don't flash anything. There are always risks associated with every flash attempt. I suggested flashing only because you asked "Should i get back to the OLD R8BE001 ..... "
"It did not upgrade all the firmware" only because *you* did not perform the correct steps to successfully flash all the firmware files.
