NOTE:

I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this Kernel
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you.

What is MultiRom?

MultiRom is one-of-a-kind multi-boot mod. It can boot any Android Rom as well as other systems like Ubuntu Touch, Plasma Active, Bohdi Linux or WebOS port, once they are ported to our device. 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 the modified TWRP recovery. You can use standard ZIP files to install secondary Android Roms, daily prebuilt image files to install Ubuntu Touch and MultiRom even has its own installer system, which can be used to ship other Linux-based systems.

I am not the developer of MultiRom. All Credits for it goes to Tasssadar, the actual developer of it.

Features:

MultiBoot any number of Android Roms

Restore Nandroid Backup as secondary ROM

Use for example Ubuntu Touch or Desktop alongside with Android, without the need of device formatting

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 messing with boot sector and data partition. 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 Stock Rom zips again. Make backups. Always.

​

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 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 the Rom, follow these steps:

Go to MultiRom -> List Roms and select the Rom you want to update.

Select "Flash zip" and Flash the 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 something, for example a Kernel, which is Distributed as a Whole boot.img (eg. Qassam 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 - No Need to Explain this I Think!

- 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 a Developer Option.

- Re-Patch init - This is available only for Ubuntu. Use it when Ubuntu cannot find the root partition, i.e. after apt-get upgrade which changed the init script.
