Thanks guys
So... Nexus 4 with stock 4.3, rooted and faux123's kernel, both normal or compatible mode, rebooted after every driver installation/unistallation before, now i can't even install drivers (it says driver installation failed). Yes i'm using last version o SuperSu and busybox.
Sorry for not answering sooner, bad day yesterday...
I'm very close to you, n4, cataclysm (very nearly stock 4.3)... And for me works fine, so we should get it for you!
I'm using it as user (no root install), and normal mode, so should not be big problems for you.
Let's try that. So that now it fails completely for you, I would do that (if fails, tell me and I'll give next steps).
1. Check you have SuperSu 1.51. It's the only root working fine but now. Even flash it again just in case it was bad during previous flash
2. Download again last v4a fx.
3. Uninstall driver from v4a, then uninstall app. Remove Viper4Android folder from sdcard.
4. Reboot
5. Extract the apk for v4a fx 4.3 from zip and install it as user, simply clicking in explorer.
6. Run v4a fx to install driver (a8). Reboot
7. Check you are in normal mode (no safe, no compatible. If needed, change and reboot).
8. Choose v4a in music effects
9. Play some music and change some effects in v4a. Tell me is its working and changing sound, or which problems do you have.
I'm sure we'll get it!
