Hello!

I have a Razr I XT890, and I just unlocked my bootloader. I have a few questions about ROMs and the TWRP:
My objective is give a phone faster and cleaner for my father...now the phone has too much stock apps and older android version.

1 - Is there any 5.x ROM or 6.x ROM available for XT890?
2 - The CyanogenMOD "spyder" model will not be compatible, right?
3 - Why I need to use the TWRP 3.x for ROMs 6.x, if is not possible to have ROMs 6.x on that device?
4 - Is there any boot logo to flash with fastboot to get away from the bootloader advice?
5 - If I want to get a Retail ROM 4.x, I will need to flash with TWRP 3.x or TWRP 2.8.x? Is there any diference?

Thanks for the atention guys!
