[ROM][RK3188][MTCD] da-anton ROM [beta3]

[da_anton]

Hi everyone,
this ROM is based on the latest JY ROM. I built the ROM with the MTCD ROM builder (http://forum.xda-developers.com/and...ns-development/tool-mtcd-rom-builder-t3475444)

It is tweaked for speed! Mainly I removed some apps which seemed unnecessary to ME which are otherwise using RAM. I also optimized the build.prop. Mainly the dalvik/ark and GUI parameters. It boots on my Xtrons GS HU in under 20sec (car logo to launcher) and has roughly 430-450MB free RAM after boot as you can see on the screenshot. The ROM looks stable to me. Give it a try if you like and let me know if you can feel a difference regarding speed and smoothness.

READ:

• No warranty if you brick your HU
• so far I just tested it with my GS based headunit! So no guaranty that it works on yours
• This is my first ROM and I only have one unit which is obviously in my car. So support is limited so don't expect updates
• I will not include xposed and I'm not planning to do so
• no dmcu.img included. You have to flash that one separate if you want to update your MCU

Design goals:

1. Stability - stick as much to the stock ROM as possible
2. Performance - remove whats not necessary and tune the rest

Download:

• https://drive.google.com/drive/folders/0BzxkkrRwpR3EMzY5VFpnU2tWOUU?usp=sharing

Installation:

• as usual: put dupdate.img on GPS card and flash via system update; wipe before if you are coming over from another ROM
• you have to wipe data twice because the partition scheme is changed

Credits:

• malaysk
• wskelly
• bravonova
• shawndak
• everyone else I forgot

Changes:

[beta 3]

• enabled boot animation again as disabling caused massive problems (reboots & buttons not working anymore)
• reverted busybox update

[beta 2]

• fixed problems with memory unify (aka FUSE); a wipe is advised in case of an upgrade
• disabled boot animation -> faster boot (NO animation should be displayed!, thanks to shawndak for the hint)
• upgraded busybox to latest version
• set I/O governor to noop as that one uses less CPU cycles
• adjust read-ahead values to new memory size
• included AdAway
• removed Viper4Android due to busybox problem; I currently don't have time to fix it
• removed BasicDreams
• removed HoloSpiralWallpaper
• removed LiveWallpapers
• removed LiveWallpapersPicker
• removed PhaseBeam

[beta 1]

• ROM build with MTCD ROM builder (http://forum.xda-developers.com/and...ns-development/tool-mtcd-rom-builder-t3475444)
• ROM now based on stock JY-ROM 2016/09/20
• SuperSU integrated by myself with MTCD ROM builder
• unified memory support for user data (also known as FUSE support), thanks malaysk!
• some smaller tweaks to build.prop. But I don't think they gain a lot of speed/memory

[alpha 2]

• added MTCDVD4
• added MTCBackView
• added Viper4Android
• removed PrintSpooler

[alpha 1]

• based on JY-20.09.2016 ROM from wskelly

Nice work! It is just basic stuff needed for the HU yo run great. I already have the latest Joying stock rom and KD MCU and it's working great, I'll try your rom.

Just a question does MTCDVD4 and MTCBackview means we loose DVD playback and reverse camera view?

So far: yes as I don't need them. But I think I will include them in the next release as some of you might use them for sure.

Hi !, first thanks for your work, I'll give it a try but in the next release...I need the reverse camera optino

Good job btw. Running it now. But I installed mtcmovie4 because I use music videos sometimes

 

[gtfour]

the better thing for complete a rom is the mtcmusic with next folder.
thanks for your great work

Tips: just Place removed APK in links below, so that people can just restore the apps they want

Good idea. I uploaded a ZIP to the Google folder which includes most of the removed apps. Unzip that file to an SD and install as usual

Included is:

• Calendar.apk
• Galaxy4.apk
• GoogleCalendarSyncAdapter.apk
• MTCAVIN.apk
• MTCDVD4.apk
• MTCPhoto4.apk
• Exchange2.apk
• Gmail2.apk
• GoogleEmail.apk
• MTCBackView.apk
• MTCMovie4.apk

Anyone want to create a github project and work on a build together? Setup some makefiles or some scripts to do some automation, make it repeatable, and provide some options that you could chose from maybe during the build.

I definitely like that idea! Here we go: https://github.com/da-anton/MTCD_ROM-cooking

But I'm not very good in programming. So my stuff maybe rather basic

 

[solmer]

Greeeat idea !!! I'll try to help as much as I can.....

Excellent work

Mtcmovie4 installed. No movies showing up. Strange.

EDIT: Not your fault! i messed up and used wrong version of MTCMOVIE, =) now it works

 

[da_anton]

to separate MTCD ROM modding from my ROM I created a separate topic: http://forum.xda-developers.com/and...ns-development/tool-mtcd-rom-builder-t3475444

Everyone is invited to join!

alpha2 online

alpha2 is uploaded. I have NOT tested it so far. So would be great if someone else could tell me if removing the PrintSpooler has any negative side effects or the ROM is fine.

Changes:

• added MTCDVD4
• added MTCBackView
• added Viper4Android
• removed PrintSpooler

 

[solmer]

That's great

I've not checked yet but in the link http://cuentosperdidos.org/safe-remove-android-apps people sya that is safe to removed.....let's try

Just a suggestion - can you install the xposed framework? It's available here (first link) and I can confirm that it works beautifully with JY 1.90:

What is exposed used for in the HU?
What does viper do? And does it work?

Xposed has a bunch of modules that plug into it - stuff that is super low level. The two items I use it for are AppSettings to change the DPI on individual apps. (like making the banners in google maps smaller, and the map area bigger) and something called MinMinGuard that nukes advertisement areas in other apps. There are literally hundreds of things that you can do with it.

Viper is a fancy EQ. I dont use it as the built in one is sufficient.

As I wrote in the OP: definitly not! To be honest: xposed is a pain in the ass! It can do pretty cool stuff but there are so many things that often go wrong and most ROM builders just don't include it because it makes so much trouble. I personally prefer stability over features.
