you did the BCH sweep wallet using your still visible and current BTC pre-fork addresses, it appeared to work, and yet you can't see any BCH in your Coinomi wallet. Right?
Correct. Everything seems to work, nothing happens weird on any software, be it the electrum wallet or coinomi. Only, no BCH shows up anywhere.
I think I'll just take the electron cash route soon. Moving coins to a safe wallet, then importing the electrum seed to electron cash. Seems to be the most reliable way, even though I wanted to stay away from Electron cash if possible.
BINGO! BINGO! BINGO!

I had been avoiding Electron Cash after the warnings I had read a few weeks back, but I had already moved all my BTC from Electrum to a new Coinomi address and had completely uninstalled Electrum, so since there was apparently no way to access my BCH in Coinomi, what was there to lose? So I installed Electron Cash (make sure you *only* download it from
http://www.electroncash.org/), chose the default install path, used my old Electrum wallet backup, and there it ALL is!!!!! BCH magically appeared. I sent .02 BCH to my Coinomi BCH address. Yep, it's there. It was fast too.
No "Sweep wallet" BS with fruitlessly attempting every private key associated with my old Electrum addresses that had pre-fork BTC. Just installed Electron Cash, put in my password with which I had protected the old Electrum wallet, and there was *all* my BCH, showing all my old BTC transactions. Very cool. Only thing I changed was the display from "mBCC" to "BCC" (under Preferences, Appearance).
So a BIG thumbs up to Electron Cash, and a big BOO to Coinomi (who still hasn't responded to my open ticket in now 4 days and 14 hours, I think I'll just close it, maybe with a link to this post...).
I'm happy now. I hope this helps some other folks here!
