Do a checksum on both the file on your card and the one on your PC and see if they match.
Is your region changed emunand running stable? No problem while renaming folders and other common problems?
Check to see if the cias aren't corrupted. (Bad (micro)sd card ?)
I had no trouble installing SDF on my region changed emunand.

Since you didn't mention a price range its kinda hard.
But I'd recommend OnePlus One, if you can get your hands on a invite. It's USD 350 for a 5.5" 64Gb high-end phone.
You don't need a flashlight app as CM11 has one already (just draw a V on your locked screen and the flashlight turns on).
And...
Where did u buy it?
I'm trying to find the best place to get a black 9.1 Jap
Nippon seems to ship either 8.x or 9.x, Play-Asia seems to ship more 9.x than 8.x.
Nippon is way cheaper( USD ~170 + USD 18 Fedex) than Play Asia (USD 210 + USD 15 S&H)
