Introduction

MultiROM is one-of-a-kind multi-boot mod for Moto G5S Plus. It can boot any Android ROM, besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs.

Features:

* Multiboot any number of Android ROMs

* Restore nandroid backup as secondary ROM

* Boot from USB drive attached via OTG cable

You can also watch a video which shows it in action in general.​

Warning!

It _is_ dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. But it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.​

Installation

1. 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 2 parts you need to install:

Modified recovery (TWRP_multirom_sanders_YYYYMMDD-xx.img) - download the IMG file from second post and use fastboot or Normal TWRP recovery if you have or any other third party image installers from Google Playstore.

MultiROM (multirom-YYYYMMDD-v33e-UNOFFICIAL-sanders.zip) - download the ZIP file from second post and flash it in recovery.

2. Via MultiROM Manager app

We do not have Official Support, an unofficial APP can be downloaded from second post)

You current rom will not be erased by the installation.

Download links are in the second post.​

Adding ROMs

1. Android

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

Using USB drive (not tested yet)

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.

In some cases, you might need to flash patched kernel - get coresponding patched kernel version from second post and flash it to the secondary ROM sama way you flashed ROM's ZIP file.

Explanation of recovery menus

Main menu

- Add ROM - add ROM to boot

- List ROMs - list installed ROMs and manage them

- Inject boot.img file - When you download for example kernel, which is distrubuted as whole boot.img (eg. franco kernel), you have to use this option on it, otherwise you would lose MultiROM.

- Inject curr. boot sector - Use this option if MultiROM does not show up on boot, for example after kernel installation.

- Settings - well, settings.

Manage ROM

- Rename, delete - I believe these are obvious

- Flash ZIP (only Android ROMs) - flash ZIP to the ROM, for example gapps

- Add/replace boot.img - replaces boot.img used by this ROM, this is more like developer option.

- Re-patch init - this is available only for ubuntu. Use it when ubuntu cannot find root partition, ie. after apt-get upgrade which changed the init script.​
