What I meant to say was that I tried putting the U2's 2.8.7 TWRP on the Lucky and, Flashify will flash it but it didn't work. I thought that, since the Lucky was KitKat that it might work. No such way ! By the way, there's a new OS that has surfaced over in Europe and it's called LINEAGE os . Yes, it does have a variant for the W5. Check it out, I'm sure you're always looking to get the drop on a new and tasty OS that can be rewritten to include the Ultimate2 . This looks to be aserious successor to the CM fame enjoyed recently. I'd bet serious money that you'll be able to " morph " their stable ( nightly ) file available at their site. Called LINEAGE os. Maybe you haven't heard of it. Brand spanking new .
