mobile

So, phone got bricked after i tried to downgrade
Loaded up some "custom stock firmware" (pic related)
fixed it, back to 4.4.2 instead of 4.4.4
however

Now i cant torrent APKs / launch external ones, (japanese Pad, any game on the play store, most apps on the play store, torrented apks of course )
if i download and launch them it just crashes
as well as this not counting as a root, so im stuck not being able to use towel root.
Trying to update to 4.4.4 via the phones settings does not work .

Any advice/ help?
I would very much appreciate it,.
