[MOD] [Experimental] MultiROM v33 for Moto X Pure Edition/Style (clark)

Introduction

This is a port of Tassadar's MultiROM, a multi-boot mod for Moto X Pure/Style. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.

This is still very experimental!

I've only tested this with stock M as the primary ROM and AICP M as the secondary ROM

Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from USB drive attached via OTG cable

Warning!

It _is_ dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.

Installation
The MultiROM Manager app does not currently support the Moto X Pure Edition

1. Via MultiROM Manager app
This is the easiest way to install everything MultiROM needs. Install the app and select MultiROM and recovery on the Install/Update card. If the Status card says Kernel: doesn't have kexec-hardboot patch! in red letters, you have to install also patched kernel - either select one on the Install/Update card or get some 3rd-party kernel here on XDA. You are chosing kernel for your primary ROM, not any of your (future) secondary ROMs, so select the version accordingly.
Press "Install" on the Install/Update card to start the installation.

2.Manual installation
Firstly, there are videos on youtube. If you want, just search for "MultiROM installation" on youtube and watch those, big thanks to all who made them. There is also an awesome article on Linux Journal.

MultiROM has 3 parts you need to install:

• Modified recovery (TWRP_multirom_clark_YYYYMMDD.img) - download the IMG file from second post and use fastboot to flash it.
• Patched kernel - You can use either one of the stock ones in second post or third-party kernels which include the patch, you can see list in the second post. Download the ZIP file and flash it in recovery.
• MultiROM (multirom-YYYYMMDD-vXX-clark.zip) - download the ZIP file from second post and flash it in recovery.
  
  

Your current rom will not be erased by the installation.
Download links are in the second post.

Adding ROMs

1. Android
Go to recovery, select MultiROM -> Add ROM. Select the ROM's zip file and confirm.

Using USB drive
Untested on clark

During installation, recovery lets you select install location. Plug in the USB drive, wait a while and press "refresh" so that it shows partitions on the USB drive. You just select the location (extX, NTFS and FAT32 partitions are supported) and proceed with the installation.
If you wanna use other than default FAT32 partition, just format it in PC. If you don't know how/don't know where to find out how, you probably should not try installing MultiROM.
If you are installing to NTFS or FAT32 partition, recovery asks you to set image size for all the partitions - this cannot be easilly changed afterward, so choose carefully. FAT32 is limited to maximum of 4095MB per image - it is limitation of the filesystem, I can do nothing about that.
Installation to USB drives takes a bit longer, because the flash drive is (usually) slower and it needs to create the images, so installation of Ubuntu to 4Gb image on my pretty fast USB drive takes about 20 minutes.
Enumerating USB drive can take a while in MultiROM menu, so when you press the "USB" button in MultiROM, wait a while (max. 30-45s) until it searches the USB drive. It does it by itself, no need to press something, just wait.

Updating/changing ROMs

1. Primary ROM (Internal)

• Flash ROM's ZIP file as usual, do factory reset if needed (it won't erase secondary ROMs)
• Go to Advanced -> MultiROM in recovery and do Inject curr. boot sector.

2. Secondary Android ROMs
If you want to change the ROM, delete it and add new one. To update ROM, follow these steps:

• Go to Advanced -> MultiROM -> List ROMs and select the ROM you want to update.
• Select "Flash ZIP" and flash ROM's ZIP file.

Note that swapping roms between internal and external is not supported (yet). Also, after flashing a factory image to the primary system and boot partition, make sure to immediately inject MultiROM before first boot, otherwise the secondary ROMs will be deleted.
