2. Immediately boot into recovery and flash patcher
3. boot up the device.

Patcher + system(For people who for some reason, can't use flashtool):
1. CLEAN flash the zip
2. boot up device.
YOU HAVE TO BE ON STOCK OREO FOR BOTH METHODS

Possible Problems and Solutions (PLEASE READ):
1. Apps randomly crash
2. Phone does not boot up
3. No sim detected
Solutions:
1:
for substratum users, disable the theme for the app crashing
if apps are just randomly crashing out of nowhere and substratum isn't the cause, please clean install the patcher.

IMPORTANT
Installation Procedure:
Patcher(RECOMMENDED METHOD):
1. CLEAN flash FTF
2. Immediately boot into recovery and flash patcher
3. boot up the device.

Patcher + system(For people who for some reason, can't use flashtool):
1. CLEAN flash the zip
2. boot up device.

DO NOT FLASH ANY OTHER KERNEL EXCEPT DUALITY KERNEL

 

[_LLJY]

The changes that make this ROM tick:
This ROM was built for stability and efficiency from the ground up, there are little added features or customization features like in existenZ, I'm leaving the feature packed ROM for AOSP

1. the interactive governor is heavily modded with the best possible efficient values and it is designed to ramp down into lower efficient frequencies when under sustained load. This is what makes the ROM efficient as it reduces heat and power consumption when doing intensive tasks.

2. Scheduling changes, the big cores have been tweaked to handle more tasks as they were under utilized. This improves efficiency and performance.

3. Debloating, Sony apps have been replaced by their google counterparts in order to function properly in the Google ecosystem. Not to mention this too saves battery. Not only that but useless sony apps have also been removed

4. Storage management(coming soon) in the future, a smart SSD manager will be added to the ROM. Its job is to optimize and manage the storage to work as optimally as possible. It will work in tandem with smart cleaner to provide a fast and efficient storage subsystem.



Lastly,
Addressing concerns about odex vs deodex

On LP and MM, there is no significant difference between the two in terms of speed and functionality
On Nougat, there is a significant difference,
On MM and LP, ART compiles the apps ahead of time on first boot, therefore apps are theoretically odexed once the ROM has booted

On Nougat/Oreo, Android boots without compiling the apps and instead compiles apps in the background during times of low load/idle. THIS SIGNIFICANTLY AFFECTS PERFORMANCE AND BATTERY LIFE*

Therefore, deodexing is generally not recommended on Nougat

Any screenshots?

its just a stock based rom, whats the point? it looks exactly the same as stock

Which version based 417 or 442 ? @_LLJY

 

[_LLJY]

Which version based 417 or 442 ? @_LLJY

417, there is no 442 custom kernel(also because im waiting for androplus to merge my pull request for overclocking)

 

[karrouma]

417, there is no 442 custom kernel(also because im waiting for androplus to merge my pull request for overclocking)

Yes it is stock rom.
Working nice with some modifications and some tweeks.
My stock xz rooted have 90% same modifications.
Thank you @_LLJY

I updated my stock xz to .442 but using v21 kernel and working fine with twrp3-1-0

 

[pk-air]

It is based on 417 but which region? I know it isn't matter much but good to know.
It based on 417 single or dual version? Yes you have converters to flash along but what if we dont flash it?
Thank you for your hard work!

 

[Nimadroid]

Hum good rom I test it soon ad feedback you

So are you on this ROM or 442?

 

[_LLJY]

Alright guys, working on polishing final release; it's going to be awesome

 

[_LLJY]

Next version will have significant battery life increase

 

[karrouma]

So are you on this ROM or 442?

I have three sony xz dual
One with your rom Duality ROM replaced RomAur
One with eXistenZ N | v5.6.0
And one with stock rom .442

Seems like your rom have same battery life than stock but little faster
The stock one is with my wife
And i have the two others

It's not even done yet haha
Internal testing shows that next version might have at least a 25% increase in battery life
