    MultiROM is a one-of-a-kind multi-boot mod. It can boot any Android ROM as well as other systems like Ubuntu Touch, once they are ported to that 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. 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.

    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.


    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.​



    IMPORTANT
    1. I'm not responsible for anything, you do all this on your own risk.
    2. Once you have flashed and set up MultiROM, don't flash another boot.img using fastboot.
    3. If you want to uninstall MultiROM, just flash the MultiROM uninstaller.
    4. Your device must not be encrypted.
    5. To all devs maintaing Stock-based ROMs: Feel free to use my patched stock kernels to add MultiROM support to your ROMs.
    6. When booting another ROM, you'll notice that in some cases, you can enter the recovery of the boot.img of the ROM. Please don't use it, flash everything using MultiROM TWRP.



    INSTALLATION
    1. Install the MultiRom Manager app from the store and install the recovery and multirom.
    2. Reboot into MultiROM TWRP and flash the MultiROM installer --> Sould be done automatically.
    3. Make sure you are on a Rom compatible with one of these kernels and flash it
    4. In order to boot a secondary rom you MUST enable the "kexec workaround" option in the MultiRom settings found in the recovery.
    5. That's it. You can now go to "MultiROM menu" (Top right corner in the recovery) to start flashing other ROMs.

    Alternative installation method (if installation via the above method fails)
    1. Download the files named multirom-<date>.zip and recovery-<date>.img from here.
    2. You should use md5sum to validate the downloaded files using the provided xyz.md5 files in the same download location.
    3. Copy the files to the sdcard of your device.
    4. Use "adb shell" to open a shell on the device and use "su" to obtain root rights (adb must be set up on your computer, instructions are found on xda).
    5. Adjust the following command and enter it in the shell: "dd if=/sdcard/recovery-<date>.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel"
    6. Reboot into recovery (shutdown, then VolDown + Power).
    7. Flash the multirom zip from the sdcard.
    8. Enjoy.



    Adding ROMs
    Go to recovery, select "MultiROM menu" (Top right corner in the recovery) -> Add ROM. Select the ROM's zip file and confirm.​



    Using USB drive
    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 "MultiROM menu" (Top right corner in the recovery) in recovery and do Inject curr. boot sector. if it is not done directly during installation of the Rom.
    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 "MultiROM menu" (Top right corner in the recovery) -> List ROMs and select the ROM you want to update.
    • Select "Flash ZIP" and flash ROM's ZIP file.

    Install a stock rom as secondary

    This only works if you are using MultiRom version 33c or larger (excluding 33x-z).

    1. Existing primary stock rom
    Use these instructions if you plan to move an existing stock rom installed as primary. This guide assumes that multirom recovery is properly installed.
    • Shutdown the device.
    • Start the device into multirom recovery (VolDown + Power).
    • MAKE A BACKUP!
    • Go to "MultiROM menu" (Top right corner in the recovery) in recovery and tap "Swap roms".
    • Select the option "Copy primary rom to secondary/internal" and start the operation.
    • Wait until the operation finishes and flash your desired rom. (Alternatively you can also use any secondary rom to be the primary rom using the "Swap option" mentioned above.
    • Reboot.

    2. Fresh stock installation
    Use these instructions if you do not have a stock rom installed as primary. This guide assumes that multirom recovery is properly installed.
    • Shutdown the device.
    • Start the device into multirom recovery (VolDown + Power).
    • MAKE A BACKUP!
    • Install the stock rom via an install zip of via an FTF. NOTE: For the FTF method you need to shutdown the device and boot into download mode (VolDown pressed while connecting the USB cable; cable connected to the PC). Use for instance flashtool to flash ONLY the kernel, system, and cache image. In addition, you MUST select "Wipe apps_log"!
    • When the device reboots, let it boot up and finish the first time setup procedure.
    • Shutdown the device.
    • Start the device into multirom recovery (VolDown + Power).
    • Go to "MultiROM menu" (Top right corner in the recovery) in recovery and tap "Swap roms".
    • Select the option "Copy primary rom to secondary/internal" and start the operation.
    • Wait until the operation finishes and flash your desired rom. (Alternatively you can also use any secondary rom to be the primary rom using the "Swap option" mentioned above.
    • Reboot.

    This is some real good progress in the Z2 development. When I'm not using the XDA One app I'll properly check out this thread. Thank you so much for this. I'll throw a donation your way at the end of the month.

    EDIT:
    Personally I think the installation instructions are a little bit ambiguous. Or is that your aim for this early in development?

    Like in step one, I am assuming you need to be on an L ROM running your L kernel?
    Is the multiROM TWRP embedded into your kernel?
    The multiROM installer is the file multirom-20150113-v30x-UNOFFICIAL-sirius.zip, correct?
    When do we need to flash the recovery.img you have provided?
    Are the files under the KK/ directory needed yet?

    Sorry for all the questions, I'm curious and want to try this but I don't wanna make any errors in the installation.

    CM12 needs to be the host rom :D

    after that you can install all you want

    you need to flash the recovery.img to the FotaKernel Partition. ATM my M5-Kernel-V2-L is the only host kernel supported (therefore you need to be on CM12 as the Hostrom), more are yet to come (I work on a KK host kernel already and @AndroPlus Kernel is going to get supported soon too). The KK folder is not needed ATM, you just need M5 Kernel, the recovery.img flashed to FOTAKernel (see Recovery Collection Thread on how to do this) and then just flash the multirom*.zip and you are ready to go.

    Hi Myself5, thanks for making multiboot rom for Z2, i always wanted to try something like this but my bootloader is "unlock allowed: no" is there any hope to run this on a locked bootloader / stock kernel or should i just complety forget about multiboot forever :p ??

    Thanks for the work.

    MR needs a kexec-hardboot patched Kernel to load any other rom's kernel. However, as you can't flash any modified kernel I guess this is not possible for you. Sorry for that.

    Hi and thanks for this beautiful feature. But I have a problem: I am on stock ROM 4.4.2 . Can I install a second ROM with a MultiROM remain on stock?

    not yet. You need a MR compatible Host Kernel (it needs kexec-hardboot). Till now only my M5 Kernel for CM has it. Wait some weeks, I'm working with @AndroPlus to get kexec-hardboot going withAndroPlus Kernel ;)

    Just like all recoverys, otg stick doesn't mount... Please use Nut's recovery TWRP as base, that works ever. Is it normal that I can't touch anything really when the MultiRom Menu comes while booting?

    Heyyy came across this and its awesome!!! So currently this mod works only for CM-based? Can I use a cm12 as a main and envi rom as my 2nd rom? D:laugh:

    EDIT: Actually I tried flashing envi rom but it couldn't boot. My orginal CM12 rom boots fine though. Maybe I'm missing something. Do I need to flash kernels to the rom?

    ... Both your questions would be answered if you would have red the OP. I use @[NUT]s Device trees for TWRP already don't know why OTG is not working for you. A recovery log would be cool (After attaching the USB use adb to get it by using the command)
    Code:
    adb pull /tmp/recovery.log
    The touch, as clearly written above the download link, is not yet working, I still need to fix this.
    Heyyy so currently this mod works only for CM-based? Can I use a cm12 as a main and envi rom as my 2nd rom?:laugh:
    No as AndroPlus Kernel now has kexec-hardboot too you can use either stock or CM12/based (I'm working on a CM11 compatible Kernel) as the host Rom and any Z2 Rom you want as secondary Rom this is because secondary Roms need no patching (exept whats done when installing my MR itself) so you can use any Rom you want.

    Are we Need to mod the ROM for that? Are that only work with Z2 ROMs?
    I would test it soon as possible with androkernel.

    as you can read above, you only need to mod the host Rom (the Rom which is actually installed to the place it "belongs to") by installing a kexec-hardboot compatible kernel. And yes, OFC it does only work with Z2 Roms, this Mod is just for booting a Rom from a different place, not to magically make every Rom compatible with the Z2 :p

      - Bug fix: Set the version number in the Mrom binaries (for automatic updates).

      I do not accept donations. But you may consider donation to Myself5 who did the original port, or to Tassadar who envisioned Multirom and did most of the implementation. We just jumped on the rolling train ;)

      I still need to fix touch inside the MultiROM menu, for now you need to use the volume buttons to navigate.

      The recovery.img is Tassadars modified TWRP to flash secondary Roms. It is needed to flash the secondary Roms.

      I just started a build on my finally completed jenkins setup. Be prepared for TWRP 2.8.5 and MultiROM v31x. Build should be up in ~15 min, and MultiROMMgr should be updated automatically too.
      Edit: It's up :p

      It appears like I fixed MultiROM (at least on the Z3 Compact) yesterday (both, graphics and booting secondary Roms with a different boot.img) . Going to do some more tests with it today and then publish it for Z3C followed by pushing an updated Version for Z2 and Z3. Sorry for letting you guys wait that long.
