Intorduction
MultiROM is one-of-a-kind multi-boot mod for Galaxy S4. 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 external SD card. 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 image above. 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.
DISCLAIMER: You take responsibility of your phone and what you flash into it, not me. You are warned!
Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from Internal memory and MicroSD Card
And since i don't feel like ripping this stuff from AntaresOne's thread, go read it here (i'm lazy): http://forum.xda-developers.com/galaxy-s4/i9505-orig-develop/mod-multirom-v28-t2864469
This is basically the same, i've done some small modifications and development to get it working on I9295.
Installation
1. Via MultiROM Manager app NOT tested on I9295, propably won't work. Don't try! (But if you do, report )
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.
Note 1: Your device must not be encrypted (hint: if you don't know what it is, then it is not encrypted).
MultiROM has 3 parts you need to install:
MultiROM - download the ZIP file and flash it in recovery.
Modified recovery - download the ZIP file and flash it in recovery or Mobile Odin app to flash the recovery.img contained inside ZIP.
Patched kernel - Download the ZIP file and flash it in recovery or keep stock kernel (CM11/based ROMs with this android_kernel_samsung_jf source)
You current rom will not be erased by the installation.
Download links are in the second post.
TWRP
MultiROM TWRP can work without MultiROM installed. Obviously most MultiROM related features won't work so steer away from them.
When formatting partitions, especially /data, do keep backups handly, even from /sdcard. As /data and /sdcard are on same partition, formatting /data formats /sdcard. Note that factory reset doesn't actually format /data, it just wipes the directory clean. But when changing fs type on /data, /sdcard will be formatted also.

Yes, this is quite nifty, i have CM12, CM11 and AOSP installed currently and latter two are running from my external sdcard (exfat). Granted, they are somewhat slower but for now those installations are only for testing. I ordered a miniusb to female usb adater so i can even install roms to usb stick . Not very handy in everyday use, but helps when you want to just test something...
Personally i use this modified TWRP quite lot now that it has f2fs and exfat support.

First attempt didn't work out for me....
Currently running WizCyan 4.4.2 ROM
When entering recovering mode and trying to install multirom-20141203-v30-UNOFFICIAL-jactivelte.zip from SD-card i end up with an error 7, no harm done...
Already made a nandroid backup of this rom so i think i'm gonna install patched recovery-image with Odin and after that multirom.zip through recovery.
That way i will be able to restore the Nandroid from the MultiROM menu, right?
@spegelius you say you have CM12 as primary ROM. I presume it's NOT the Dual? And it doesn't have to be patched before installing?

Did you install the TWRP? I haven't tried with CWM. Error 7 sounds like old recovery or something... not sure (had those problems with AOSP updater and some versions of CWM at some point).
I don't use dualboot, best not to mix it with this. Actually i think dualboot break multirom (need to flash multirom again after dualboot rom flash) and vice versa.
Haven't tried nandroid restore with MultiROM but i think it should be possible? Also if i got this right, if you restore your nandroid as an multirom installation, you'll have two instances of same rom; the main rom and the one installed from nandroid.

Just installed TWRP with Odin and after that MultiROM and it works...cause SuperWizCyan works great i'll leave it as Primary ROM for now and will install CM12 and StockROM on my SDcard...to be continued!

Hmm , i wonder if the latest CM12 installer works with MultiROM since it has custom partition format script which allows it to detect f2fs/ext4. Make sure you have backups before trying.

Okay, i even moved my Nandroid Backup to my PC before proceeding.....you can never be too careful!
Installing CM12 to my SD-card now.....
* I have to keep the screen 'alive' while installing CM12 with MultiROM, otherwise when the screen goes black...well i had to reset the phone....
* 2nd attempt it seems to work, no errors and after pushing the Reboot-button screen goes black again...> reset
* I can see the Boot-screen but touch-screen not working so trying to cancel Boot from Internal doesn't work so it auto-boots... >> found it ... Use Volume Buttons!
* But: i can see that CM12 is listed as 2nd ROM
* So now i have to find a way to get into the menu to choose ROM to boot
And... how do i install the GAPPS for this 2nd ROM? >> found it...you can do it within TWRP>MultiROM #cool
Also installed MultiROM manager apk hoping it would give me boot options but (obvious) it doesn't work on 9295 for now.
For testing purposes i set the 2nd ROM to boot in MultiROM setting (trough TWRP)....it seems that the black screen is a problem of TWRP, not MultiROM
Oh well... booting CM12 doesn't work for now...will post multirom_log soon

See attached multirom_log,txt

In the log there was mention about kexe-hardboot failing... Is WixCyan a TW rom? Is the kernel in it KEXEC-HARDBOOT patched? That patch is in CM11, CM12 and AOSP (and other CM11 derivates) since their kernels are the same base. For TW, you'd need some modified kernel.

So it works only for aosp and cm roms?

No without patched kernel. It might work if the TW rom isn't the first rom, but instead a multirom.

Update: i'm there
Now i have SuperWizCyan as Primary (internal) ROM and SammyStockTW as secondary on my SD-card
I made it harder then needed cause i forgot to make a Nandroid with TWRP instead of CWM so i had to re-install CWM to get my 1st ROM back.
(If you really wanna know what i did, please ask, for now i will spare you the details )
For now, as you can see in the previous post, CM12 doesn't work for now....we'll wait and see and do some more testing!
But hey, it worked and so far so good.....1 thing i didn't read about is if there i going to be an option of app-sharing like DualPatcher does. App-sharing with data-sharing would be even better for my banking apps and Whatsapp to work on both ROM's.
Thanks again @spegelius !

Great, apparently there's KEXEC_HARDBOOT patch somewhere there or it's not needed .
For CM12, another installer zip is needed, which has the normal /system format and mount commands. I'll see if i get it done.
No app sharing, at least automatically. In the I9505 thread someone suggested moving the apps/data to sdcard or something...

Oh and the problem with screen timout is known, didn't remember to mention it. Screen timeout can be disabled in Settings.

Interested in replace CWM 6.0.5.0 with TWRP. Not sure if ready to use the rest of MultiRom setup yet. Is TWRP stand-alone capable of replacing CWM in a single ROM setup?

Yes, TWRP works without MultiROM. There are few checkboxes, like Inject MultiROM that need to be disabled when installing roms for example, but basic stuff works without multirom.

@spegelius
Ehhm, small correction for OP Installation - Modified Recovery:
It's a tar-file on your Gdrive, no zip-file for installation by recovery multirom_twrp_20141204_1838.tar.md5
Not tried Mobile Odin yet but I know PC Odin swallow tar-files.
About warning TWRP format of /data also include /sdcard. /sdcard is soft or hardlinked(?) to /data/media/0
Can the relationship between fstab of TWRP and mount points of S4A be a good place to start tracing, or is this all fuse managed?
Recovery.log of CWM 6.0.5.0 got me thinking:
W:Unable to get recovery.fstab info for /sdcard during fstab generation!
Can mount points be somewhat off? (at least for CWM) . The reason is that delete dalvik cache take less than a microsecond, as if it has not been executed. Delete cache and zip install has been good.
Will update to TWRP using Odin from PC and follow up.

Yes WizCyan is TW ROM and should work....?
see: http://forum.xda-developers.com/galaxy-s4-active/development/rom-super-wizcyan-s5-style-t2874424
I'll ask @JASONRR if he can implement KEXEC-HARDBOOT in next version.
I have to do some clean install cause i can't restore my Nandroid Backups (all CWM-related). :crying:

Introduction
MultiROM is one-of-a-kind multi-boot mod for Moto X Play. 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. 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, 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.​
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, once they are ported to the Moto X Play
* 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 factory images again. Make backups. Always.​
Installation
1. Via MultiROM Manager app (We do not have Official Support, so this is not an option for us yet)
This is the easiest way to install everything MultiROM needs. Install the app (Not for Moto X Play) 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 (If you want to use Kexec) - 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_lux_YYYYMMDD.img) - download the IMG file from second post and use fastboot, TWRP or Flashify app to flash it.
Patched kernel - you can find it in the second post. Download the ZIP file and flash it in recovery. You can use any 3rd-party kernel which include the patch.
MultiROM (multirom-YYYYMMDD-vXX-lux-signed.zip) - download the ZIP file from second post and flash it in recovery.
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.​

FAQ and other notes
Device encryption
Since v32, MultiROM supports encryption on this device (it has to be added for each device separately). It works only with Android-based secondary ROMs and the secondary ROMs don't know the device is encrypted, so they would allow you to encrypt the device again - do not do that. If you're using password, pin or pattern for the encryption, MultiROM will ask you for the password on boot. If you're booting the primary ROM, then Android will ask you for the password _again_ - unfortunately, there is no way for me to pass the "unencrypted" status to Android. If you're booting secondary ROM, MultiROM will ask you for the password again after the reboot - that's because I have to unencrypt the /data partition after the ROM's kernel is loaded.
I could omit the second password prompt when booting secondary ROM by temporarily saving the password somewhere, but that's obviously unsafe. So is using encryption with unlocked device though, so I might add this later.​I have not tested it yet, as i never used ENCRYPTION on my device, will try to see if there are issues and more users for this use case
About security
In order to make multi-booting possible, MultiROM has to sacrifice some security measures. Firstly, on secondary Android ROMs, /system is not mounted read-only. While there are other things preventing malicious software from messing with /system, this might potentialy make it easier for such software to attack that system.​
What do the ROMs share?
All ROMs are separate, except /sdcard, which is shared between all Android ROMs.​
How many ROMs can I have?/Where are the ROMs stored?
You can have as many ROMs as you can fit in your /sdcard. All the ROMs are stored in /sdcard/multirom/roms or on an USB drive. This folder is unaccessible in Android, to prevent mediascanner from scanning it. You can either in recovery, or obtain root and go to /data/media/0/multirom/roms.​By default /external_sd is mounted and is used to store the ROMs.
The menu with all the ROMs won't show up during boot, how to fix it?
Either re-flash the MultiROM zip or go to recovery, Advanced -> MultiROM -> Inject curr. boot sector.
The reason for this is that something rewrote your boot.img, which happens for example when you flash a kernel. MultiROM's boot menu is part of the boot image, so it has to be added into it again.​
Can I flash secondary roms on Micro SD?
Yes but it's is very slow, internal storage is much better to flash secondary roms.​
How do I flash Gapps in Secondary ROMs?
After AddRom and is done, go back and Click on the installed Secondary ROM, you will see one of the option to 'Flash Zip', click and install Gapps. Then you can reboot into secondary ROMs, do gapps installation before rebooting otherwise as usual need to deal with SetupWizard FC, at least thats what I observe in my device.​

No-kexec workaround (version 4)
As of this version you need to manually enable the no-kexec workaround.
Actually, depending on the developer, (s)he may have already enabled it. Nonetheless, you can still choose to override the settings:
Go to TWRP -> MultiROM -> Settings
and enable the No-KEXEC workaround option
once you do you'll also have the option for ADVanced settings, please see below for a detailed description, though in most cases the default should suffice.​
Explanation of the no-kexec workaround advanced options
(the Info page is supposed to provide the same information as here, but I haven't added that yet)
1- Use no-kexec only when needed
This should be the default for most users, the other options are more intended for advanced uses (kernel debugging, and such).
If MultiROM detects a kexec-hardboot enabled kernel in primary slot, it will use the standard kexec method to boot the secondary. If on the other hand it does not detect that the kernel supports kexec-hardboot then it will use the workaround.​
2- ... but also ask for confirmation before booting
Same as option 1 above, but in addition you will be presented with a confirmation message, if the workaround is about to be used:
3- Ask whether to kexec or use no-kexec on booting
If the kernel in primary slot does support kexec-hardboot'ing then you will be presented with a choice of which method to use
If the kernel does not support kexec-hardboot then you'll be informed as in option 2 above​
4- Always force using no-kexec workaround
Forces the no-kexec workaround to be used, even if the kernel in primary slot has kexec-hardboot support​
Options 2 and 3, always present the user with a GUI confirmation, whereas option 1 and 4 will act as instructed without prompting the user.​
Visual feedback provided by the Booting... card
Regular kexec-hardboot boot
Booting using no-kexec-workaround
​
How does all this work, etc
The workaround:
MultiROM TWRP recovery works, and is able to flash ROMs to secondary
MultiROM in essence works (in particular, able to change the mount points during bootup)
what does not work is being able to use the secondary ROM's kernel (due to the lack of kexec-hardboot kernel and tools)
So how do we deal with booting any ROM if we can't use the proper kernel for the ROM?
Easy :
Upon selection of the ROM during MultiROM boot menu, we do the following:
"flash" secondary boot.img to primary partition slot
initiate a full reboot (secondary boot.img is in primary slot)
let the ROM auto-boot up on second boot
The good part:
It works.
.
Every secondary ROM has a boot.img file we can easily access to use the workaround; when you flash a ROM in MultiROM TWRP, not only are the "virtual" system, data, and cache partitions created, but also the boot.img.
The secondary ROMs' boot.img will be found /data/media/0/multirom/<name of rom>/boot.img or if it's on your external ext4 in the appropriate rom folder
We use that file and flash it to primary real boot partition and then upon second boot, the correct boot.img is in place for the correct ROM.
The bad part:
Unlike secondary ROMs, the primary ROM does not have a boot.img file... since it is the primary ROM, the boot.img should always be in the real boot partition, since MultiROM expects the primary kernel to have kexec-hardboot capability, but it does not, so I just go ahead and mess with your primary boot partition.
Since we have no "boot.img" file for the primary, my workaround makes a backup of the boot partition and names it primary_boot.img
In version 4 of the workaround, this backup is created and used only when booting a secondary ROM. When a secondary ROM is selected it's boot.img is flashed to primary slot, upon booting into the secondary ROM, the primary_boot.img is restored.
Long story short: the difference between kexec and no-kexec-workaround
Usual kexec-hardboot MultiROM
Select secondary ROM
MultiROM detects a boot.img
MultiROM reads the secondary boot.img into memory
MultiROM initiates a kexec second boot but into the secondary boot.img from above
MultiROM continues
No-kexec-workaround MultiROM
Select secondary ROM
MultiROM detects a boot.img
MultiROM flashes the secondary boot.img into the primary boot partition
MultiROM initiates a normal second boot but with the secondary boot.img in the real boot partition
MultiROM restores the primary_boot.img and continues as usual
so the difference is in point 3... whereas normal kexec'ing loads the secondary boot.img into memory and goes from there, the workaround, actually flashes it to the real primary boot partition... and continues normally from there

Great work :good:
May I recommend possibly linking to the original post, because
(1) it's incomplete... but should do for the moment (yeah, it's a sloppy write up, but better than nothing)
(2) once certain things are updated, a copy/paste wont include them
Glad it's working for you, and if it is working properly, then perhaps i need to add it to that post
Happy MultiROM-ing

No worries, the original no-kexec-workaround info is still here http://forum.xda-developers.com/showpost.php?p=64248526&postcount=4
If I update any information, it will still most likely be there (unless I end up doing on the HTC 10)
(in which case i would update the info)
post updated to include Moto X Play, nice work :good::good:
lingering boot.img was deprecated btw, there are other ways to "break" things.... but it's a lot more difficult now

After installing Multiboot system ringtone volume shoot up to high at beginning later it comes down to normal value.
Has anyone faced this issue. I tested it in two Rom and confirm it. The issue is noted on internal ROM. @GtrlCraft

I have tested it in Stock Rom as well as in another rom. This issue is seen when I boot into internal ROM.
When any alert -message or phone ring.
First ring is way too louder then gradually sound become normal. The sound is so loud that I think the speaker would die

dunno what i'm looking for / at,
but have you confirmed:
booting that particular ROM
flashed with MultiROM TWRP
but not injected does not produce this issue?
.
booting that particular ROM as a secondary slot also does not produce this issue?

Booting a ROM from multi Rom twrp with out injected does not produce any issue. Second ROM on MultiRom does not have the issue...
I tried Stock Moto as well as another Rom as primary in both the case high volume issue is noted.

Introduction
MultiROM is 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.​
Installation
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 + one optional (deprecated) :
MultiROM (multirom-YYYYMMDD-v33x-odin.zip) - download the ZIP file from second post and flash it in recovery.
Modified recovery (multirom-YYYYMMDD-recovery-odin.zip) - download the ZIP file from second post and use a recovery to flash it into the FOTA partition
DEPRECATED: Patched kernel - You can use those kernels on most Marshmallow and Lollipop based primary ROMs to add kexec boot support.
Be aware that those patchers will be updated when possible after kernel sources updates
Kexec support no longer required thanks to the no-kexec workaround by nkk71.
For convenience reasons, I enabled the workaround by default if kexec is not found.
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.
Recommended values are :
Cache : Keep default value
Data : Minimum 4000
System : 1000 is enough for most installs
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 Android to 4Gb image on a pretty fast USB drive takes about 20 minutes maximum.
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.
OPTIONAL: Reflash the kernel patcher to add kexec support
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.
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.​

Downloads
1. Main downloads
MultiROM: multirom-2016MMDD-v33x-odin.zip
Modified recovery (based on TWRP 3): multirom-2016MMDD-recovery-fota-odin.zip
2. Uninstaller
MultiROM uninstaller: Unavailable for Odin due to the already considerable SONY ELF format port
Reflash a ROM or a boot.img without injection (or the v33x zip) to remove MultiROM bootimage from your device.
Then delete the "multirom..." folders from internal & external storages.
If you don't want MultiROM menus in recovery, re-flash a normal TWRP, but it is not needed,
those menus don't do anything if MultiROM is not installed.​
How to install for the first time
Flash the 2 MultiROM zips as explained
Reboot to the FOTA Recovery (Volume +)
In MultiROM TWRP, Add a ROM, set everything properly
Wait for the ROM to be installed (can take a while)
In MultiROM screen, choose the ROM location
For the concerned ROM, "Flash zip" for wished zips (GApps, SuperSU, Addons...)

FAQ and other notes
About security
In order to make multi-booting possible, MultiROM has to sacrifice some security measures. Firstly, on secondary Android ROMs, /system is not mounted read-only. While there are other things preventing malicious software from messing with /system, this might potentialy make it easier for such software to attack that system.
Next, MultiROM doesn't work with /data encryption. Not many people who use custom ROMs also use encryption anyway, so that isn't much of a concern.
What do the ROMs share?
All ROMs are separate, except /sdcard, which is shared between all Android ROMs.
Why is my USB connection to computer not detected ?
Uncheck the "Enable ADB" option in MultiROM Settings.
How many ROMs can I have?/Where are the ROMs stored?
You can have as many ROMs as you can fit in your /sdcard. All the ROMs are stored in /sdcard/multirom/roms or on an USB drive./external SD card. This folder is unaccessible in Android, to prevent mediascanner from scanning it. You can either in recovery, or obtain root and go to /data/media/0/multirom/roms.
Can I have different versions of Android working alongside?
Yes.
MultiROM recovery says it's 2.8.4. Why isn't it updated to 2.8.4.*highernumber*?
It is, it just shows wrong version.
The menu with all the ROMs won't show up during boot, how to fix it?
Either re-flash the MultiROM zip or go to recovery, Advanced -> MultiROM -> Inject curr. boot sector.
The reason for this is that something rewrote your boot.img, which happens for example when you flash a kernel. MultiROM's boot menu is part of the boot image, so it has to be added into it again.
Something wrong happened, I lost something or it's really laggy
You have been warned about making backups & the fact this is more experimental than stable.
You alone will be responsible for loosing data or having an usable ROM when you really needed it.
Everyone in this thread will try to help you, but we can't do backups of your data ourselves.
Thanks for your understanding, remember to read the previous comments and please try to help each other.​

Hi mate I'm interested to try this mod. I'm currently on Xperia ZL c6502 10.7.A.0.222 stock rooted with unlocked bootloader and xz dual recovery. Is it enough to try this or any thing more stuff I need before I can start?

@Chippa_a, about keeping stock ROM 5.1.1 as primary, AFAIK if the recovery is flashed to fota partition, the device doesn't boot into recovery. Then how can it be used in stock ROM?
EDIT: Oops, didnt see the changelog.

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. I am not certainly sure about the compatibility with stock Roms, I still need to test this yet.
5. Your device must not be encrypted.
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
-> Download and flash the MultiROM recovery from the DOWNLOADs section using "fastboot flash recovery <path-to-recovery.img>
-> Use the recovery to flash the latest multirom zip from the DOWNLOADs section.
-> In order to boot a secondary rom you MUST enable the "kexec workaround" option (enabled by default) in the MultiRom settings found in the recovery: BEWARE that this workaround re-flashes the boot-partition every time you boot a secondary rom, so don't boot secondary roms too often, as it may brick your device on the long term! We still need to fix kexec such that exessive utilization is less risky
That's it. You can now go to "MultiROM menu" (Top right corner in the recovery) to start flashing other ROMs.
NOTE: The touch screen doesn't work if you use a MM/N ROM as a base/primary ROM.
ALTERNATIVE INSTALLATION METHOD
-> Download the latest TWRP multirom recovery from the downloads section.
-> Use a terminal emulator, obtain su, and use the following command Adjust the following command and enter it in the shell: "dd if=/sdcard/<name-of-recovery>.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel"
-> Follow the steps in the previous method to install multirom
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 DRIVES
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.

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.

Great job Dev

Hey @drakonizer i tried to flash the recovery bit I'm facing a black screen after rebooting in recovery. I'm on cm12.1 with m5kernel 11.2. I probably did something wrong but what?... I only flashed the recovery

Will 4.4 as primary work

You should have flashed the TA update to enable booting directly to recovery. If not, the recovery won't work. Booting into recovery only works using the hardware button combo, and not from Android/adb.

Thanks you're the boss I will try it now

Updated recovery and multirom zip added with support for Android Nougat and custom stock kernels. Please try and report.
Also, OP has been updated. Looks like Multirom is pretty stable for daily use now. I personally tried it with N as primary and LP as secondary and it worked like a charm.
If users of amami/togari want me to port it for their devices, please PM me so that I can send you test builds. Once I deem them to be stable, I will open threads for them.

I read but i am from brazil and my english isnt the best ones, thats why i am lost. My idea, is, use as primary the 5.1 rom to daily use... but i am lost HOW to start, what kernel should i use...
Please, can you help?

Okay, I will describe it in detail once more, and hopefully this will be the last time.
-> You can have any ROM as primary, but 5.1 is preferred if you want touch screen support in the multirom menu (the OS choice menu).
-> Flash the latest TA update that enables the recovery partition. The thread is available in the general section.
-> Download the latest multirom recovery from the downloads section
-> Download the latest multirom zip
-> Flash the recovery using fastboot (fastboot flash recovery recovery.img)
-> Boot into recovery using POW+VOL DOWN and use it to flash the multirom zip you downloaded earlier.
-> Enter the multirom menu by tapping the icon on the top right corner of the recovery home screen.
-> Follow the menu to install your secondary ROM.
-> Once that's done, reboot, and you should see the multirom menu pop up
If you still didn't understand, there are multiple guides and videos on the internet. The process is pretty much similar for all devices, so you don't have to look for Xperia Z1 exactly.

Thank you for your time! I appreciate it. Two last questions. There will be difference between primary or secundary boot? as performance?
and if i want just to install the second boot ( keep the ressurrection marshmallow as primary) it can be done too?
Thank you and sorry

The only difference would be boot time.
Yes, you can use MM as primary, but touch on the multirom menu will not work and you'll have to use the volume buttons and power button to move and select.

Friend, i am still on MM Rom, 6.0 with the same kernel, now i want to make the lollipop as my secundary boot
i flashed the twrp of multiboot via fastboot mode. I´ve turned on my z1 (power + volume down) (Could see the new twrp menu) In the INSTALL option, flashed the zip file of multiboot. After that ( i did not reboot my devce) on the addRom menu, installed a lollipop rom (that i know that works with the same kernel as my MM rom)
but it starts the install thing and get a status FAILED and erase an incomplete rom... something like this. .. and i cant install it.... i´ve tested two different lollipop rom... am i missing something?

Introduction
*** Note I am not a MultiROM expert. I wanted to create a place to share and buried in @KINGbabasula's thread is not ideal. Per his request, I've made this thread...
*** Special thanks to @KINGbabasula for his original thread, and to @martinusbe and @nkk71 for entertaining my endless questions, and providing invaluable help when asked.
MultiROM is one-of-a-kind multi-boot mod for Oneplus One. 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.​
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.
You can install it either from MultiROM Manager app or from this guide:
Note 1: Your device must not be encrypted (hint: if you don't know what it is, then it is not encrypted).
MultiROM has 3 parts you need:
MultiROM - download the ZIP file from second post and flash it in recovery.
Modified recovery - download the IMG file from second post and use TWRP (flash image file), fastboot or Flashify app to flash it.
Patched kernel - Your Primary ROM's kernel should have the no-kexec patch applied, but should be OK if not as MultiROM will check.
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. If desired, you can go to Advanced -> MultiROM -> List ROMs, select your ROMcan flash individual zips, one by one, such as GApps or SU.​
2. Ubuntu Touch (Note I have not tested this nor do I use Ubuntu Touch.)
Use the MultiROM Manager app to install Ubuntu Touch.
Ubuntu Touch is in development - MultiROM will have to be updated to keep up with future changes in Ubuntu, so there's a good chance this method stops working after a while and I'll have to fix it.​
3. Firefox OS (Note I have not tested this nor do I use Firefox OS.)
Firefox OS is just another Android ROM from MultiROM's point of view, so add it as if it were Android​
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 Advanced -> MultiROM in recovery and do Inject current 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.

FAQ/FYI
Here are some common questions and answers with MultiROM:
I can't flash a different recovery on my device because the option is not there.
Most likely, the fstab file in the recovery needs to be fixed. You'll probably need to perform the fastboot steps in #2 below.
How to use fastboot to flash a recovery image to your device:
To flash back to another recovery:
Boot your device into fastboot mode.
Copy the recovery img file you want to flash to a place where you have fastboot installed. You probably did this already when you installed TWRP over your stock recovery so you could flash custom ROMs.
Open a terminal/command window in the directory where fastboot.exe and the recovery.img file are, and type: fastboot flash recovery recovery.img (where "recovery.img" is the actual name of the recovery file you want to flash).
None of my secondary ROMs will boot:
You probably need to run Restorecon on the secondary ROM to modify its selinux contexts. To do this:
In MultiROM TWRP, click the MultiROM options in the upper right corner.
Select "List ROMs"
Choose your ROM from the list
Click the "Run Restorecon" button
Reboot into that ROM
I am not seeing the boot menu from MultiROM to select a ROM.
Make sure you injected MultiROM into your primary ROM. To do this:
Flash the MultiROM zip file to your primary ROM.
Click the MultiROM options in the upper right corner
Select the "Inject boot sector" button
Reboot
If you still have trouble, see @nkk71's post here with more information.

Tried with Lightning kernel (which supports KEXEC-hardboot) and tried booting a secondary rom. It leaves me with an error popup saying "KEXEC-hardboot support is required to boot this rom". No-KEXEC workaround isn't working either.

can my 16GB-device work??

Great mod. Thanks NoSpamDan for keeping it alive!

Going to need more details than that... and thanks for the log.
What ROM primary and secondary?
Did you inject the boot image on your primary?
Try flashing your primary as both a primary and a secondary and see if you can add another secondary. This is still in the testing phase but I have Slim7 as my primary and no issues with secondary ROMs. I don't normally even need restorecon on them when I test (unless it gets stuck at the kernel splash screen)...
EDIT: From your log:
Code:
[ 3.375133] multirom: kexec -u test has failed, kernel doesn't have kexec-hardboot patch enabled in config!

Sure, why not? You can use an external OTG drive to keep ROMs on. Depending on how much space your ROM & Data occupies will limit what you can do on such a small storage device.

@nikhil18 forgot to enable KEXEC in V35. Use V34, it's enabled/working fine there.

So it seems that the latest version of LK has broken Kexec, so no need to worry about that. Just the No-Kexec workaround that's problematic.
I'm currently using HalogenOS, and any secondary rom won't work. I injected the boot image on the primary rom, otherwise I would be booting straight into the primary rom.

Well I edited my last response to include a line from your log indicating that the kernel does not have the kexec-hardboot patch.

I know that, I said that the latest version of Lightning Kernel has broken kexec-hardboot. All that needs to be fixed is the no-kexec workaround.

developer options still force closes on nougat roms when you install the nougat rom as secondary so how is this nougat friendly?

This depends on the rom itself. I believe a commit is needed in order for it to work properly.

Great question... it's Nougat-friendly because you can install Nougat ROMs as secondary. The Developer Options problem is a bug...
As a work-around, you can install your problem Nougat ROM as a Primary, enable the Developer Options there, then move it to a Secondary slot...

Indeed, a secondary ROM needs this: https://review.slimroms.org/#/c/22989/

I'm running a marshmallow and nougat rom together with the last version of multirom?

For nougat compatibility, moving to latest @nkk71 multirom modified_twrp 3.0.3-0 is real better 2017-01-27:
https://github.com/nkk71/android_bootable_recovery/commits/android-7.1-mrom
https://github.com/multirom-htc/Team-Win-Recovery-Project/commits/android-7.1-mrom
BTW, MultiROM' OPs should clarify one for all that multirom.zip' s trampoline works fine with all unmodified recoveries twrp/cwm (primary rom install/update only): modified_twrp is only needed for managing 2nd roms.
Of course, using un-swapped unique modified_TWRP recovery is always much "cooler" (I didn't had much success explaining that to p880' users with : how to rom/kickflip and twrp/shuvit...), and NoKexec workaround is a more complicate behaviour.

Even after flashing v33e, Multirom manager says I'm running v33b... Is that normal?

I have a version of 3.0.3-0 built, but I couldn't get my multirom zip file to show the boot menu/boot sector. I did flash the zip and injected it but no luck. I have reached out to @nkk71 for ideas on this, but it might be best if he responds here when he has a chance.
For now, I'll put the new TWRP in Post #2 and here if you want to try it. Keep a previous version around just in case you need to fastboot flash it to your device: TWRP_3.0.3-0_multirom_bacon_20170213-01.img

Yes, it's because it's pointing to @nkk71's repo, and it's also using his changelog I believe. I'll have to review, but manual installation is best for now. What the app is most useful for right now is managing your ROMs...
