Sorry for the inconvenience, I have a Rogphone 5 16/256 with Bootloader unlocked only, I have read the instructions but I have not understood some things well: I have the stock firmware with Bootloader unlocked, I just need to install the twrp, root and kernel and enough? Do you need to do some wipes? Thank you so much to those who will help me.
if you already own ex kernel manager or franco kernel manager app, you can use those to flash the kernel.zip. then there´s no need for installing twrp.
you don´t need to do any wipes. just follow the instructions in the first post.
make sure your phone is rooted, before flashing the kernel.
