[Moto Maxx Original Android Development] ChazzMatt:
Well, with CM13 or any custom ROM for Quark you can always install

BHB27 kernel

to increase performance. It's based on CM kernel but more options. That kernel has extra governors and such. And there are battery saving options in [MENTION=5321318]Debuffer[/MENTION]

kernel Intelli- profiles

that you can run with BHB27 kernel.

I run CM for the extra user options available. Other ROMs have even more options but CM is enough for me. If it wasn't for CM dev [MENTION=2228410]Skrilax_CZ[/MENTION], the Quark probably wouldn't have any custom ROMs or kernels as all the custom ROMs use his CM kernel. You can't have a custom ROM for a device without a kernel. While you can port a ROM, it still needs a device-specific kernel.

If you go over to the

Kinzie (Droid Turbo 2/Moto X Force) forum

-- the 2015 successor to our 2014 Quark -- they never got ANY official ROM, no custom kernels. First, the Verizon-branded Droid Turbo 2 bootloader was never unlocked. And while the sibling Moto X Force is easily unlocked and rooted, all that device got was UNOFFICIAL TWRP and an UNOFFICIAL CM12.1 -- which was last updated in February 2016. Only one outdated unofficial Lollipop ROM and no custom Marshmallow ROMs whatsoever. It's a sad situation.

No dev like [MENTION=2228410]Skrilax_CZ[/MENTION] stepped in to help them with that device, like he did with our Quark.

Over here on the Quark, what [MENTION=2228410]Skrilax_CZ[/MENTION] did was the foundation of ALL our XDA development choices. He coded CM and kernel, which caused other ROMs to appear. What a lot of people don't realize is ALL the Quark custom ROMs (Lollipop and Marshmallow) all use his CM kernel. ;)

Then we got

official TWRP

from [MENTION=5747496]baybutcher27[/MENTION] -- taking over from the unofficial TWRP [MENTION=1220096]respider[/MENTION] had started.

[MENTION=5747496]baybutcher27[/MENTION] also maintains two custom Quark ROMs --

Mokee AOSP

and

Resurrection Remix

-- in addition to his BHB27 kernel and TWRP.

More recently [MENTION=7237874]NepoRood[/MENTION] started

Bliss ROM

and

Android Open Kang Project ROM

, which works on all Quarks.

If that's not enough choice, [MENTION=6069596]calsurferpunk[/MENTION] mainstains an

"unofficial" CM13 ROM

which is a hybrid of CM13 with some Resurrection Remix features.

[MENTION=7109882]iiWoodstocK[/MENTION] has a

"stock"-based Motorola Marshallow ROM that is TWRP-flashable, which works on ALL Quarks

-- XT1254, XT1225, XT1250, and uses the BHB27 kernel (which of course is based on [MENTION=2228410]Skrilax_CZ[/MENTION] work).

And these are just the Marshmallow options! ;) I haven't even mentioned the Lolllipop ROMs that still work, if for some reason you wanted them. (I'm still running CM12.1 Lolllipop on both my phone and my wife's phone.)

So, while it's easy for people to forget about CM when other snazzy ROMs come along, for our Quark they are all built on the foundation of what [MENTION=2228410]Skrilax_CZ[/MENTION] started and still maintains. He first got CM12 Lollipop working with Motorola Kitkat kernel sources (before Motorola gave us Lollipop), then CM12.1 with full Lollipop kernel, then got CM13 Marshmallow ROM working with Lollipop kernel sources (MONTHS before Motorola released Marshmallow for any Quarks), then coded a CM13 Marshmallow kernel.
