Goodbye Lollipopalooza... Hello Marshmallicious!!

Marshmallicious Banner

This started out as a personal project... a way for me to learn how to develop and custom features for Android. And I decided to share my work with the amazing Android community... something to give back to the community. Back then, this was a ROM called ThunderKat, based on Android 4.4 KitKat. Over time, it evolved into Lollipopalooza, based on Android 5.0. And now, here's Marshmallicious, based on Android 6.0.

Now, before you go on ahead, let me be clear about one thing. This is and will remain a minimal AOSP based ROM. It will include a small, but useful set of features... features which add a bit more flare to Android AOSP. Beyond this minimal feature set, this will also include some relevant spit and polish (bug fixes and asset/image updates). As time progressed, so did the quality of the work behind the features this ROM offers. Whenever I look back at a feature I developed before, I look for ways to improved. If you expect a lot of additional features, I recommend using one of the more popular ROMs available like CyanogenMod, SlimRoms, ParanoidAndroid, etc.

I develop and maintain this ROM on my own for the most case, occasionally seeking help and porting useful features and fixes that others here in the community have developed. You will see all the relevant references in the cherry-picked commit in my GitHub repositories.

Due to my limited availability, I will now no longer support Lollipopalooza builds

Now that I'm done with the fancy introduction, let's get down to business...

Instructions:
1. Download the Marshmallicious ROM package and the Prerequisites package
2. [OPTIONAL] Download the GoogleApps package
3. Reboot into recovery [A custom recovery like TWRP is required]
4. Wipe as required
a. Full wipe when coming from another ROM
b. Wipe cache and dalvik-cache when flashing a Marshmallicious update
5. Flash the packages in the following order
a. Prerequisites package
b. Marshmallicious ROM package
c. [OPIONAL] GoogleApps package
6. Reboot and let the device boot up and remember that the first boot will take a while since this is a de-odex ROM

Root:
I do not support SuperSU because it is closed-source and, hence, cannot be audited. Anything granting low-level privileges to apps and process need to be open-source and auditable. But I will not blankly turn down support requests involving SuperSU if you have chosen to root your ROM using SuperSU.

That said, I am closely following the development of systemless open-source Superuser by @phhusson as well as the SELinux policy changes by @doitright. This is still experimental and may not support all root apps yet.
Because this is currently experimental, this ROM is not pre-rooted. But I have provided a separate ExperimentalRoot package. This package contains a modified boot image with the su binary, init changes and SELinux policy changes and has been built from source. The su binary was built with the latest changes in @phhusson's Superuser GitHub repository. The init and SELinux policy changes are a slightly varied version of the patch created by @doitright. Also included in the zip is the Superuser apk built with the latest changes in @phhusson's Superuser GitHub repository.

I have branches in my GitHub repository which have the SELinux policy and init changes required for systemless Superuser which include all doitright's changes as well as my modifications.
platform_external_sepolicy
platform_system_core

Instructions:
1. Download the ExperimentalRoot package provided above (make sure it matches the ROM release date)
2. Flash the boot image included in the ExperimentalRoot package using fastboot [fastboot flash boot boot.img]
3. Install the Superuser apk included in the ExperimentalRoot package as a regular app

Theming:
This ROM support RRO/Layers themes. But please be aware that not all RRO/Layers themes support Android Marshmallow yet. If you encounter force closes after installing a theme, reboot into recovery mode and delete /vendor/overlay.

Layers/RRO Themes Info:
1. Join the BitSyko Google+ Community for the latest information and themes
2. Download the Layers Manager app to install/uninstall/preview RRO/Layers themes
3. Download the Layers Showcase app to browse available RRO/Layers themes
4. Visit this XDA thread for a comprehensive list of RRO/Layers themes

Help and troubleshooting:
1. Ask for help if you need, but make sure you do your research first.
2. Be patient. It could take a few minutes to flash the ROM.
3. If you flashed a kernel which replaced the SELinux policy file, you may encounter errors and issues. To recover, you will need to reflash the ROM boot image.
4. If you get "failed to mount /dev/block/platform/sdhci-tegra.3/by-name/APP", unmount the system partition and try again
5. If you flashed a kernel with SELinux disabled like the one provided by @USBhost on a previous build, make sure you flash that kernel after flashing the update (before you reboot), or you will get a bootloop and will have to perform a recursive restorecon on the /data partition to restore the SELinux contexts.
6. If you have a folder created in TWRP recovery mode which you cannot access when you boot up the ROM, you will need to perform a recursive restorecon on that folder restore the SELinux contexts.
7. Be ready to provide a clear description of your issues and please provide logcats, dmesg logs and kmesg logs whenever possible.

Marshmallows are always delicious... but be careful!!! Make sure you know your limits!!! If you don't know what you are doing, the marshmallows provided here could be life-threatening and render your device inedible. Every marshmallow here has undergone extensive scrutiny, but there is always a chance that something slipped through the cracks since baking is more an art than a science. So if you use the marshmallows here, don't hold the chef responsible for baking these goodies (me!)

Found it. It's actually a kernel change... well, a change in the fstab. Changing the forceencrypt mount flag to encryptable makes it encryptable, but with encryption disabled by default.

Change these line in the kernel initrd fstab.flounder & fstab.flounder64
Code:
/dev/block/platform/sdhci-tegra.3/by-name/UDA   /data               f2fs       noatime,nosuid,nodev,errors=recover                                   wait,check,forceencrypt=/dev/block/platform/sdhci-tegra.3/by-name/MD1
/dev/block/platform/sdhci-tegra.3/by-name/UDA   /data               ext4      noatime,nosuid,nodev,nomblk_io_submit,errors=panic    wait,check,forceencrypt=/dev/block/platform/sdhci-tegra.3/by-name/MD1
to
Code:
/dev/block/platform/sdhci-tegra.3/by-name/UDA   /data               f2fs       noatime,nosuid,nodev,errors=recover                                   wait,check,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/MD1
/dev/block/platform/sdhci-tegra.3/by-name/UDA   /data               ext4      noatime,nosuid,nodev,nomblk_io_submit,errors=panic    wait,check,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/MD1
or fstab.flounder in the flounder device tree.
