I was able to root my SM-J100VPP Phone... even though it's FRP Locked
using KingRoot v5.3.7 that came out June 2018... I was able to replace my bootsamsung.qmg and bootsamsungloop.gmg files
using Root Explorer... I made a BootAnimation Install for Samsung Phones from Galaxy 7 and Galaxy 6 BootAnimations...
I think it looks good... Two types of Samsung Animations...

File name is Samsung_S6_S7_BootAnimation_Combo.zip
Glad to get rid of the old Red Verizon BootAnimation. I put FreedomPop on my SM-J100VPP
Before I did that I had it working With An Ultra Mobile SIM Card
That I took out of my other Phone... It was an easy setup.
My SM-J100VPP was also Samsung FRP locked out and was able to Bypass that
with adb shell pm uninstall -k --user 0 com.sec.android.app.setupwizard
( went to maintanance mode first and enabled USB debugging )
Then booted up the phone .... checkmarked allow USB debugging from the popup
and used the adb shell command to remove the setupwizard launcher and made Easy Mode
the Default Launcher... Check Out KK Easy Launcher... for another nicer Easy Mode Launcher.
