[ROM][5.1.1_r3] SlimLP - Build #7 [03.06.2015]

[ChronoMonochrome]

SlimRom is a custom android operating system. The main goal is to offer users a slimmed down but still feature rich alternative to other android operating systems.
The entire SlimTeam work together to bring you this tailor-made beauty straight from Android Open Source Project (AOSP) source code.
All of the sources can be publicly viewed through GitHub and Gerrit.

SlimLP is currently in alpha stage, some settings are already in place, much is still missing and would come with time. Stay tuned!

Thanks for recommendation, lol. I do what I like, if you don't like it, then skip it.

I like what u think
Btw please fix the bug quick
I will wait for your fix

NO ETA. If bugs would be fixed an easier than to write about them, it is obvious nobody would write about them.

@ChronoMonochrome
I think need to remove link for Chainfire's root because root is included in SlimLP.
And thanks for rom, good job

It has not any preferences for root, though, that's why there's link in OP.

Is this ROM have In-call low volume issue like Omni @ChronoMonochrome ? Do I have to apply your fix for this ROM also ?

Normally you should not need to, as low incall volume fix already applied. However, it would be better if someone who does calls often would confirn or refute it, as I have found some changes in sources that may interfere with fix and not sure if it's working.

Geez...my main thought was: isn't it too alpha to waste YOUR time for it?
I mean - their own page is saying, that rom lacks many functions....
I am fan of slim roms, but...

 

[dixee]

thank you for your great work chrono, i love slimrom. i try this rom today, and removed some not needed apk from installation zip file, like audio fx, browser etc before flashing, and then no sound at all at my phone? this because i remove audio fx or not? cause when using cm12, whenever i removed audio fx, sound still work properly

UDPATE: i try to clear dalvik & cache, and fix permission through twrp, sound working again

other thing is:
-sim toolkit not displayed in app drawer
-a little bit laggy, etc when open app drawer with apex launcher or switching app
-no performance control yet?

 

[kentone]

Root options are in developer options, pushing build number repeteadly ?

No need to worry about that - if I spending time on this, then I don't do it for nothing. I build it most for myself - but ofc wanted to share with everyone who are interested in that.

There is no problem with deleting audio fx, maybe try to reflash ROM and delete some things more carefully.

other thing is:
-sim toolkit not displayed in app drawer

Same problem - I'll investigate into it later.

-no performance control yet?

There's no performance control implemented yet - use nofrills or similar app.

In indeed, there are ONLY enabling/disabling root, without any other preferences.

yes i have done with fix permission and clear dalvik & cache only from twrp

now sound is ok

I don't know if it's just for me or not, but I noticed worse performance of the runtime and math operations on latest builds - all benchmarks has showed the low results I have ever seen(and it's not only for first run). I've uploaded new build - seems that this bug was fixed.

Changelog:

• build ROM with Uber toolchain 4.9 and kernel - with Linaro 4.9.3
• enabled JustArchi optimizations v4 for lollipop
• extreme kernel optimizations based on commit by @ace2nutzer
• added RRO layers 2.1 support

First boot might take significantly more time than usual - but it's definetely better than have worse performance.

 

[ace2nutzer]

I don't know if it's just for me or not, but I noticed worse performance of the runtime and math operations on latest builds - all benchmarks has showed the low results I have ever seen

I suggest to check ROM + Kernel flags to make sure that u don't break IEEE or ISO rules/specifications for math functions
After that u'll notice best Benchmarks results
