KERNEL-HELP (sorry if wrong section)

adb remount is not permitted
after reading about it i heard you can modify the kernel (default.prop) to fix this error?
i have done so and i would like to know if compiling annd flashing the modified kernel will work, and are there any chances of bricking?

BEFORE EDITING
ro.secure=0
ro.allow.mock.location=0
ro.debuggable=1
persist.sys.usb.config=mtp,adb

AFTER
ro.secure=0
ro.allow.mock.location=0
ro.debuggable=1
persist.sys.usb.config=mtp,adb
persist.service.adb.enable=0

"persist.service.adb.enable=0" this line was not there, so will adding it affect it?
i have uploaded the kernel without the modifications applied at the bottom of this post (stock samsung gti-9300 4.1.2 XXEMH1)

KERNEL HERE

Thanks in advance!
