[KK 4.4.2][ROM]Mackay OMNI ROM (27-Feb-2014)

[kasper_h]

I have been sharing my CM7/CM9/CM10/CM10.1/CM10.2/CM11-based builds for several devices. MackayROM was first based on CyanogenMod sources, but I decided to move over to Omni as base for my ROM.

About Omni: Omni is a free, community built, aftermarket firmware distribution of Android 4.4 (KitKat), which is designed to increase performance and reliability over stock Android for your device.
Disclaimer: I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you have any concerns about features included in this ROM before flashing it! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.

If you run into errors, I may not be able to solve it!

If you know a solution to a problem, either upload it yourself to Gerrit Code Review or contact me through pm.

The ROM is based on Omni sources with the following changes:
-Mackay Kernel:
-Set of cherries picked from gerrit (differing by the day)
-Some additional patches I did myself to the source code

Feature request are OK, but remember:
1. I try to stay close to stock
2. I will not include additional apps, unless they can be build from source
3. The time I spend on features depends on how much I like them myself

Although it is possible to enable ART, this is not advisable:
-Takes long to convert from Dalvik to ART on first boot
-Needs more RAM
-Can cause soft reboots
But off course, YMMV -> light users may have better luck

Changelog of 27-Feb-2014
-Omni codebase of 26-Feb (e.g. new bootanimation )
-QS Ribbon is gone

-Custom kernels can be used only if specific for OmniROM => currently none

dirty flash on yesterdays cm11.0 nightly didn't worked for me...caused (soft) reboots after displaying the sim code entering screen a few seconds...next try is with full wipe.

Kasper, I know how much time and effort you put into making OMNI work with our devices. I just wanted to say a big thank you, for making this a real thing. You are awesome

Did you read the instructions? First flash should be after a factory reset + /system wipe
I tried a dirty flash myself, resulting in a bootloop

 

[jv.batista]

Just out of curiosity, what was the problem?

Downloading and flashing...

BIG BIG THANK YOU...

You mean with the data connection?

I still don't know what the real problem is. If I build my kernel with the Omni build system, data won't work. If I build my kernel with the CM11 and replace the Omni-build kernel for this CM11-build kernel, data works.
There are several differences between Omni & CM11:
-ramdisk differences (but adjust Omni ramdisk to make it almost identical to CM11 does not help)
-kernel image itself (it is not the same size, even though it is build with exactly the same toolchain)

I have spend many-many hours on this, but haven't been able to find it. Therefore, I decided to take the simple approach of using the CM11-build kernel as a prebuilt kernel for my Omni builds.

Yes I read it, but tried it anyways ...and my post/feedback was meant as a warning or tip for all others, not to try it without! Sorry for the confusion!

Don't worry, I actually like it when people post these things as people don't always read the instructions anyways so having some additional warnings throughout the thread are fine with me

 

[bunbury]

no "Themes" option (snif, snif)

 

[hollandais]

Factory reset, system wipe, flash rom, flash gapps, OK, no FC.

the only thing i noticed, beside the mackay settings fc was the broken layout in the sim unlock screen...

ps: swiftkey makes settings fc during configuration, I miss battery percentage and still have a 3 to 4 seconds lag when receiving a phone call until the screen lights up...

 

[avishay89051]

thanks!! i downloading now!!

Thank you Kasper, working fine here ! OMNI FTW !

ps: swiftkey makes settings fc during configuration,I miss battery percentage

1. It fcs during setup when you launch it from the app drawer but if you go into System Settings -> Language & input , and you check SwiftKey and enter it's settings from there, it works to be configured with no FC. I think Switfkey is not updated to Android 4.4.2 or has an issue I think. Then you can use the keyboard.

2. Go to System Settings -> Battery -> Battery indicator, and select your desired icon with percentage.

Also for those that want RAM status and Clear all button in Recents Apps Window (Long press Home button pop-up) You can find those settings in System Settings under Interface section, click More.
