Flashed xDelete a couple of weeks ago and my car has been performing great in RWD only configuration. 2015 F30 Msport package.
I also used an old Iphone 6 running iOS 10.x.x, can't remember exactly which right now, but it worked great and had no problem recognizing the ethernet. I used these from Amazon as well to hook everything up.

Overall car is quick and definitely kicks in traction control now during hard acceleration in which it never did in the AWD configuration. No funny noises and is fun to drive with the DSC off, as well over 2,000 miles driven since the flash.
Spent years in the Japanese RWD cars (300zx, RX7 and an old 77 Celica) and I was missing that somewhat so this helps scratch that itch.
It does snow considerably here in Utah, so I will be switching back when it does, but it's great for fair weather driving for sure.
