Hey guys, i'm on 4.2 with the d850. I unlocked my phone on stock and then flashed fulmics 4.2. When I put the Vodafone sim in my device( i'm usually on att) the phone says network locked. Does anybody have a fix for this?

I have a noob question/sugestion , can you add support for a Xbox one controller, I cannot get mine to be recognised by the Rom ( had the same problem on the stock mm). It would be wonderful to have a brief explanation if what I said ends up not being possible/too much work.

Just wanted to say thanks. Had my LG G3 for a couple of days (rooted and installed Fulmics 2.7 the first day), and so far I'm very pleased.

Really great ROM, you guys are the first developers I donated money to, I feel it's high quality and defiantly worth it!

I did notice my D855 battery runs hotter than usual after flashing, I'm using the regular kernel, not xceed.
Battery is draining quite fast, but I'll have to keep checking for more accurate information.
I never changed kernel before, kind of scary for me.
Do you have any suggestions?

Also, if possible, would be nice to:
1. add a dark theme for entire ROM, mostly in Settings, Notification, Quick toggles.. Instead of white.
2. add to Fulmics Tweaks under settings, an option to long press Recent Apps which will switch between the last two opened windows.
2. add to Fulmics Tweaks under settings, an option to hide Sync toggle notification pop up.

    ok, as a lot of people want to know the progress on marshmallow, here you go.

    first, marshmallow has changed A LOT, more than I expected, and the work will take longer. what I can tell you for sure is that until now these tweaks have been ported over:
    - all "status bar" tab tweaks
    - notification led tweaks
    - heads up/volume delay tweaks
    - longpress back tweaks
    - lockscreen tweaks
    - advanced power menu

    about last one there will be a new tweak to change power menu style (classic or lg). only the classic style have advanced options though (at least on the first update), as you can see in screenshot below.

    all other tweaks have still to be ported and most of them need to be completely re-wrote. remember, there is no source code of lg stock rom that means all those mods have to be written by reversing framework/apps, which takes longer than writing normal java.

    p.s: added Netflix fix into HUB-Fixes.
