Unofficial build of SlimKat

Dont post in official threads please. I may have messed something up and i dont want to bother other people because of my mistakes.

After leeching for years on XDA (didnt even had an account) i finaly decided to give something back to the community.

Features:
  • Im using the build scripts from Slimsaber
  • Features of Slimsaber but not all are working!
  • Used newest Linaro 4.8.3 (2014.04) optimized for cortex-a15 from here for kernel and rom.
  • Did some patches so it compiles with strict-aliasing :victory:. But i hate those freaking pointers. So maybe i messed something up.
  • all the nice placebo compile flags: -O3 -mcpu=cortex-a15 -mfpu=neon-vfpv4 -mfloat-abi=softfp -funroll-loops -fomit-frame-pointer
  • Other flags:BOARD_USES_HGL := true, BOARD_USES_OVERLAY := true, USE_OPENGL_RENDERER := true, TARGET_USES_ION := true, TARGET_USES_C2D_COMPOSITION := true
  • all the nice placebo build.prop tweaks: debug.sf.hw=1, debug.composition.type=c2d, debug.performance.tuning=1, persist.sys.composition.type=c2d, persist.sys.ui.hw=1, hw3d.force=1, hw2d.force=1, video.accelerate.hw=1, force_hw_ui=true, debug.egl.hw=1, debug.overlayui.enable=1 (actualy i dont know which ones are working and which ones arent even in the code :eek:)
  • f2fs for data and cache partition. (I think the first released z ultra rom with f2fs. Correct me if im wrong please)
  • DPI set to 280 (tablet layout).

Install instructions:
Be running at least Android 4.3 or 4.4.2 with an unlocked BL (14.2.A.0.290, 14.2.A.1.136, 14.3.A.0.681 or 14.3.B.0.757 etc)

  1. Make a backup of everything on your phone. Im not responsible for any loss of data!
  2. Boot into recovery
  3. Factory reset/wipe data
  4. Flash FormatPartitions-userdata_cache.zip
    This will format data and cache partition to f2fs
    WARNING: this will DELETE ALL DATA on your data partition. Even InternalSD! Make a backup beforehand!
  5. Flash PlaceboRom
  6. Install Gapps (I use this one)
  7. Optional: for even more placebo install this soundmod.

Not Working:
Nothing known

Not Tested (would be nice if someone could test it):
  1. ART
  2. Miracast
  3. Other models then C6833

Bugs:
  • WARNING: ADB/USB Debbuging is always enabled on reboot! So if you have sensitive data on your phone this ROM is NOT for you! (maybe someone can help. tried to disable it via build.prop and settings.db but didnt work :(. I think it has something todo with the build scripts from Slimsaber but hadnt had time to check it.)
    [*]After installing the ROM for the first time you have to go to developer settings and disable root and reenable it in order for it to work!

    Its already set to apps only after installing but it wont work! You only have to do this once. If you reflash you dont have to do it again.
  • Some graphics glitches because of "USE_OPENGL_RENDERER := TRUE" in some system apps (like Browser).
    Actualy i read somewhere that its not needed but it wouldnt be placebo without it :)
  • If you use MHL some of the screen will not be displayed :( (It displays only like 1900*1000)

Downloads:
FormatPartitions-userdata_cache.zip. Credits goto legolas83
PlaceboRom-togari-4.4.2-20140515.zip
RestorePartitions_ext4_userdata_cache. If you want to go back to another rom. Credits goto legolas83


I will try to build every two weeks.
I had only one freeze on my device (C6833) in over 1,5 months (with older builds) but consider these build as NOT STABLE. I dont want that you lose your job because of me.

Special thanks to team slimroms.

Slimsaber is the inspiration for this rom. High five @fusionjack.
If I have time i will setup a github account so contributions will be clear.
At the moment im using repos from Slimkat, Slimsaber, CyanogenMod, VanirAOSP, AOKP, Linaro


If i missed something or didnt gave proper credits i can assure that this is a mistake.
Contact me please so i can correct it.

Only changes i did to slimkernel was enabling f2fs in defconfig and some buildflags in the Makefile for kernel.
Does anyone know do i have to release my changes to be GPL compliant? defconfig is generated so i think not but what about Makefile?
Im not familiar with GPL but want to do everything correct.

OK my install instructions seems to be wrong after reading them again. :silly:
Can anyone confirm? It shouldnt work the first time.
Sorry to anyone who had problems.

I think you have to:
  1. Boot into recovery
  2. Flash PlaceboRom (you have to flash it the first time. Otherwise there might be no f2fs support in your current kernel+recovery)
  3. Reboot to recovery (after that you will have f2fs support)
  4. Flash FormatPartitions-userdata_cache.zip
    This will format data and cache partition to f2fs
    WARNING: this will DELETE ALL DATA on your data partition. Even InternalSD! Make a backup beforehand!
  5. Flash PlaceboRom again!
  6. Install Gapps (I use this one)
  7. Optional: for even more placebo install thissoundmod.

Could someone be kind and when installing the rom for the first time report back if this new install instruction is working?
It was some time ago i did it so im not sure anymore.
If somone confirms i will update op.

Any changes in the kernel need to be published, and the aosp/cm/slim code, what is less clear is whether compile flags etc (changes to make files) need to be published - my feeling is that yes they do need to be published. That's some thing I haven't done for carbon as of yet.

At the moment I think you are probably ok?

@blueether
I think i dont get you. AOSP/Slim is released under ASL. So changes made to rom dont need to be published? Altough i will when i have time. And is defconfig considered part of the kernel? Because of "make menuconfig"? Does anyone know for sure? If i interpret this and this correctly changes to Makefile have to be published but defconfig not. They even mention build flags!I know its pedantic :) just want to know. It seems there is no defenite time frame when sources have to be published?

SlimSaber-togari-4.4.2-20140515.zip (198M) exceeds the maximum size that Google can scan. Would you still like to download this file?
Download anyway
