I’m testing mokee rom, my twrp is and my cell phone is a Samsung j500m (j500ltexx), the installation procedure by twrp works perfectly, only at the time of starting the screen, when I do the entire registration process, the ROM erases and restarts several times, and never gets normal. I’ve tried two of the three rom updates (18/07/21-18 / 08 / 05-18 / 07/04) and so far nothing! I have the lollipop bootloader.
