You indicated you have read the FAQ, did you try all the items from the lost cards area including looking for backups and restoring? Have you synced with ankiweb at all? I usually move to new phones by syncing up to ankiweb on the old phone then down on the new device. Finally if you try those things and there is still an issue it would help if you could share the collection with a file sharing service somewhere so others could examine it

I was able to download the collection and inspect it.

Exported Anki collections are zip files, and my zip utilities indicated that the file was corrupt - specifically it looks like at some point while you were handling the file (copying it, etc) there was a partial transfer and the end of the file is missing?

So there may be missing data.

However, I was able to use the zip "forcefully fix" option ("-FF") to repair the zip enough to unpack it, then repack it and I was able to import it successfully into AnkiDroid in my emulator (version 2.9alpha19 - but should work for latest stable release)

The series of commands I used was this, on a MacOS laptop with OSX 10.13.3:

zip -FF collection.apkg --out collection.zipfix.apkg
mkdir TEMP && cd TEMP
unzip ../collection.zipfix.apkg
zip ../collection.zipfix.repack.apkg *

I'll try uploading the file shortly but you can experiment with those commands as well.

Ok, this was the result of the above commands if you don't have the tools to run it locally or just want to download it. Please let me know once you've fetched this file and I'll delete it, or if I don't hear back I will remove it in a couple days either way. Hope this helps
