That's what I feared.
Would it relock the bootloader ? I'd hate to have to wait another 8 days to flash this ROM again...
Here's what I found on SamMobile (https://www.sammobile.com/samsung/g...SM-J415FN/XEF/download/J415FNXXU4BSF6/283548/) :
Extract the firmware file you just downloaded. You should get 5 files:
AP (System &Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_*** (Country / Region / Operator)
HOME_CSC_*** (Country / Region / Operator)
I'll try and flash only CP (maybe BL too) and see what I'll get.
