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.

Hmm, I guess that could be a problem with my patched kernel. Have you tried toggling moto display on and off?

Yes I did..!

@Hashbang173 multi rom this was the only thing remaining
thanks dude for your hard work

Interesting I couldn't get TruPureX to be my secondary rom not sure if I did something wrong
Sent from my XT1575 using XDA Labs

Flashed TWRP-MultiRom, pached Kernel and MultiRom on Dual Sim XT1572.
Primary ROM ( Stock Marshmallow) is working fine. Wifi is not working.
On Secondary ROM , flashed AICP 15/2/2016 build with gapps and did a reboot.
After Reboot, Secondary ROM is stuck in the installation process with AICP boot animation even after 15-20mins... Any solutons? (btw Phone is hot as hell, it has never been this hot)

Wow, I didn't expect to see this on the MXP, now all we need is ports of arm GNU/linux and it'll be just like the Nexus 7 (2012) days.

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 to install:
MultiROM - download the ZIP file from second post and flash it in recovery.
Modified recovery - download the IMG file from second post and use fastboot or Flashify app 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.
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. As for the space, clean installation of stock 4.2 after first boot (with dalvik cache generated and connected to google account) takes 676mb of space.
2. 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
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.

1. Main downloads
MultiROM: Zip
Modified recovery (based on TWRP): recovery.img
Kernel with kexec hardboot patch:
Supported kernels: AK, Furnace
You need to have kernel with kexec-hardboot patch only in primary ROM
Nicely ask your kernel developer to merge this https://github.com/KINGbabasula/and...mmit/af5ef3d76f863f02c51cf860702b01536620ebf5.
3. Uninstaller
MultiROM uninstaller: Zip
Flash this ZIP file to remove MultiROM from your device. It will erase all secondary ROMs. If you don't want MultiROM menus in recovery, re-flash clean TWRP, but it is not needed - those menus don't do anything if MultiROM is not installed.

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.
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.
Where can I find files from other ROMs?
http://forum.xda-developers.com/showpost.php?p=58563378&postcount=1864
Can I have different versions of Android working alongside? How to use KitKat and Lollipop at the same time?
Yes. The systems are separated.
guide on Kitakt + Lollipop: http://forum.xda-developers.com/one...ips-tricks-t3027926/post58776196#post58776196
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.
The boot animation shows after a few seconds on primary ROMs, why?
Because the framebuffer gets blanked for a few seconds after it gets closed by MultiROM.
Can I use MultiROM without root?
Yes, if you don't use MultiROM Manager app but flash everything manually
Will I get OTAs when I have MultiROM installed? Do I lose secondary ROMs after an OTA?
Probably not, you will have to install them manually and you'll have to reinstall MultiROM
No, you won't lose secondary ROMs
My secondary ROM doesn't boot, what should I do?
Probably you forgot to inject current boot sector once, MultiROM didn't run, so /data SELinux context is set to secondary ROMs that are in /data/media so secondary /system has /data contexts.
Go into recovery Advanced > MultiROM > List ROMs > Choose the non booting ROM > Run restorecon
This will fix SELinux contexts and the ROM will boot again

Amazing, thank you bro!

Amazing! Reserved for impressions!

Woot !!!!!!! Donation incoming, as promised
Also, what kernel is yours based on ?
And finally, is it compatible with official multirom manager ?

My kernel is cm11 (not cm11s)with kexec. So it won't work on cm11s, Paranoid android and cm11s based roms.
Tomorrow is the last time I'll use pc before leaving so I may add support in multirom manager and build an unofficial version of the app because it's not officially supported

Thanks, again !
Did you try to get in touch with @Tasssadar for the frame buffer issue ?

I tried on hangouts but I guess he doesn't use it. I think I should port a few things from TWRP into MultiROM because it seems they use the same way of rendering images.

Thank you very much for your efforts,

That is really nice to have, am looking forward to use it. If the Multirom Manager app is usable here, will it be possible to install Ubuntu Touch or has it first to be ported to this phone? Just asking because I always wanted to try out Ubuntu...

That's because you need a kernel with kexec hardboot patch in secondary rom too. So you need a special kernel for color os and a special one for miui. You may try instlling the rom choosing "share kernel" option so it will use main rom kernel which has kexec

Surely I have something wrong in the kernel. Thanks for telling me that

If I try to share kernel between ColorOS and MIUI, MIUI won't boot (black screen after selecting it from the boot menu)...

Well that's expected because they use different kernels. The solution is to compile miui kernel with kexec patch and color os kernel with kexec patch. I tried only cm based roms. I'm on cm11 and I can boot slim and mahdi sharing kernel

OK, so we have to find kernel sources from Color OS and MIUI for this to work...

Introduction
MultiROM is one-of-a-kind multi-boot mod for Samsung Galaxy Note II. 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 the 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 support 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
* Install ROM to external SD card [Newly Added feature]
You can also 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
1. Via MultiROM Manager - This at present does not have support for n7100, working on getting it enabled.
This is the easiest way to install everything MultiROM needs. Install the 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 (the 3rd party kernel should also have kexec-hardboot patch) 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 . If you want, just search for "MultiROM installation" on and 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 (multirom-YYYYMMDD-vXX-t03g.zip) - the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_multirom_t03g_YYYYMMDD.img) - the zip file from second post and flash it in recovery.
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.
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. As for the space, clean installation of stock 4.4 after first boot (with dalvik cache generated and connected to google account) takes 676mb of space.

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
Firefox OS is just another Android ROM from MultiROM's point of view, so grab the ZIP file from Firefox OS' thread and 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 curr. boot sector and then reboot.
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.
To flash GAPPs for the Secondary ROMS, Go to Advanced -> MultiROM -> List ROMs and select the ROM you want to update.
Select "Flash ZIP" and flash GAPPS ZIP file.
Installing of Touchwiz as Primary Rom & AOSP ROM as Secondary.
Boot into recovery and flash Modified TWRP Multirom recovery
Next, Flash the Multirom zip.
Next, Flash the Modified Agni Stock Kernel and then flash the Mali blobs zip too and finally reboot the phone
Allow the phone to auto boot into the touchwiz rom. Once booted reboot the phone into recovery again.
Now you can flash any AOSP rom as Secondary ROM. for that follow the below steps
Select Multirom - > Add Rom -> ROM Type & Location to install the ROM -> AOSP ROM ZIP -> start the installation.
After installation is complete, go back and select the AOSP ROM that you installed and select "Remove Boot.IMG".
Reboot the Phone now and in the Multirom Manager Menu, select the secondary rom and allow it to Boot.
Note : Wifi is not working on the AOSP ROM installed as secondary, this needs to be debugged further. I am guessing it is due to the kernel version installed on the stock rom versus the touchwiz roms. Apart from the wifi, all other features are working fine.

Note : Other 3rd party AOSP Kernels like Agni, Plasma & Devil do not have the Kexec Hard-boot patch in them at present, so if you have flashed them on you primary ROM then you will not be able to boot into any of the secondary ROMS. I am working with the kernel owners to have the kexec hard-boot patch added into the kernel.
Kernels for Secondary ROMS : These Kernels are not Kexec Hardboot enabled, install them to fix the WIFI Issue on secondary ROM.

2. Uninstaller
MultiROM uninstaller : Zip
Flash this ZIP file to remove MultiROM from your device. It will erase all secondary ROMs. If you don't want MultiROM menus in recovery, re-flash clean TWRP, but it is not needed - those menus don't do anything if MultiROM is not installed

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.
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.
Can I have different versions of Android working alongside
Yes. As long as you select "Don't shere kernel" when installing the secondary ROM, the systems are separated.
MultiROM recovery says it's 2.6.3.0. Why isn't it updated to 2.6.3.*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.

Great work. @tilaksidduram

:laugh::laugh::laugh: great, I'll try this ! :highfive:
Sounds interesting!

Great work indeed

Amazing, superb, perfect, brillant, excellent You are great man, you are great. I'm waiting for this since I saw this in Nexus 4 forum. Thanks.

Great work.
Finally wait is over?

wow i'm waiting the link for download

Thank you sir, first for bring MultiRom to our Note 2, second for step-by-step instruction. I can't wait for DL and try. Amazing job.

finally multirom for note2... thanks you....

I already patched the stock kernel and it available for download in my 2nd post. you can flash it against any AOSP based Kitkat Rom for the N7100.
Currently i am running PA as my primary rom and i have installed around 6 other roms (Omni, Slimkat, Miui, Liquid smooth, CM 11, ) as secondary. All of these are working fine.
give multirom a try.

Nice....work

Let's hope the Kernel Devs include the patch so that we can also test/check it with Samsung Touchwiz Kitkat Roms
By the way Thanks @tilaksidduram for bringing this treat to us

Bug? Or problem a part those listed in op?
Inviato dal mio OnePlus One

Thanks @tilaksidduram

Thanks
Thanks bai thanks. You r the great. keep going on......

Looks very interesting definitely gotta check this out...
Thanks for the contribution to the note 2 users :good:

This is only working on aosp roms? Is possible to run a touchwiz rom and an aosp rom?

Introduction
MultiROM is one-of-a-kind multi-boot mod for Redmi2. 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 Redmi2
* Boot from USB drive attached via OTG cable
Check this video with CM13.0 base and Tesla Secondary on our device.
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. 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 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_wt88047_YYYYMMDD.img) - download the IMG file from second post and use fastboot or Flashify app to flash it.
Patched kernel *OPTIONAL* - 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. (You do not need install patched kernel if you continue to use multirom with no-kexec-workaround only)
MultiROM (multirom-YYYYMMDD-vXX-wt88047-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.
Will Miui work as Primary or Secondary ROM?
Yes, MiUI Lollipop version works with Multirom as Primary ROM, once again reiterate, only as Primary ROM. You can then install other ROMs as secondaries.
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.

Yes that is too fixed, follow the installation steps as told. Flash recovery, flash mrom-zip followed by kernel-zip.
Nothing is gonna happen to your current primary rom or any adverse affects. Go try it when you get time.

Okkkk brooo I'll try it soon and thanks once again

Nice job bud, keep it up!

great i am going to flash it

For Secondary ROMs, add the ROM zip file, then go back to that and flash Gapps too, before you reboot into it. Otherwise, as usual you need to resolve SetupWizard FC, at least thats what I see in my device.

Still confusing little bit
Can we boot different based rom? Last time i see ashish94 make video multi rom, but all rom based on aosp (tipsy & validus), so can us boot rom based cm13 & aosp, or maybe cm13 & miui too, or just same based rom?

You can boot any custom rom, except MiUI (which i have never tried). I tried GZRoms, Temasek, RR as primary and vice versa (only those zip files are there in my scared :laugh::laugh.
Btw, that video is made by me :silly::silly: and Ashish shared it in his thread :silly::silly:

Okay, currently the way it works is, which ever the partition is mounted, (default /external_sd) it is Internal, vFat is just a duplicate of it, never used it yet.
If you want to use actual Internal Storage, go to main 'Install' and use Select Storage. Then you come back here and 'Internal' becomes of that.
May be you can identify with 'XXXXX bytes' besides Internal (the size of the memory of that partition), i can at least because i use 32GB sdcard and real internal is 16GB.

It can boot any Android ROM as well as other systems like Ubuntu Touch, Plasma Active, Bohdi Linux or WebOS port.Besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable.

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

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

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.

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: There have been reports that (not only) MultiROM does not work properly with older bootloaders. Update it to version 4.13 or newer in case you have problems.
MultiROM has 3 parts you need to install:
MultiROM (multirom_vXX_tbltexx-signed.zip) - download the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_multirom_tbltexx_YYYYMMDD.img) - download the IMG file from second post and use fastboot or Flashify app 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.
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
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.

Flash this ZIP file to remove MultiROM from your device. It will erase all secondary ROMs. If you don't want MultiROM menus in recovery, re-flash clean TWRP, but it is not needed - those menus don't do anything if MultiROM is not installed.
FAQ and other notes
ALL IS IN ATTACHED FILES
**********************************************************************************************************************************************************************
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.
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.
Can I have different versions of Android working alongside
Yes. As long as you select "Don't share kernel" when installing the secondary ROM, the systems are separated.
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.
The boot animation shows only the last part on primary ROMs, why?
Because the framebuffer gets blanked for a few seconds after it gets closed by MultiROM.

Note 7 ??
You want say note 7 ported rom right ??
If not,you can flash my samsung MM rom or RR nougatd in primary rom with the good kernel and add your rom in secondary.
Only primary Rom need custom patched kernel.
Or,you canflash my kernel V4 because you need a note edge kernel even with ported Rom

Hi Micky, will we get an update from your MickyRom V3 (last Samsungupdate 26.03.17 security update) for our beloved Note Edge? Only times so asked

MultiROM Without Kexec Hardbooting Ported to OnePlus 2
A well-known MultiROM has been ported to OnePlus 2 by XDA Senior Member MZO. Except MultiROM MZO has released a modified version of TWRP 3.1.0.0. With this using the no-kexec workaround, it allows you to use MultiROM without having to flash a kexec enabled kernel. The stock ROM also works on this MultiROM port so you can have the quality camera like in the stock ROM just a reboot away. All OOS, OOS based, the MIUI port, Nougat 7.1 are compatible. If you’re using OP2, give this solution a try and pick up your ultimate ROM combo.

I have tried to install Noble Note 7 port as the secondary Rom with your MM Rom as primary with F2FS configured. I believe l have followed the steps and Noble is installed and l can select it at boot. But it just boot loops back into recovery after l select it, any clues?

Further to the above, I have been able to get the secondary Rom to boot and it works. Is there anyway to root the secondary Rom? I have tried SU 2.52, 2.65 and 2.73 system less, any clues.
EDT: Reinstalled rom and update now rooted with Magisk all good.

Hi Yossi, had experienced this too. I think it's because of the ram. Primary rom is already using high part of the ram, so it won't runnig the Race rom or Norma rom.. Therefore for the secondary rom most probably only small rom will work such as AOKP, Resurrection Remix, Slim om etc..

Thank you for your reply, but when i run aokp rom the amount of ram is the same like the primary rom, no less.

# MultiROM FAQs
• Do I have to flash any patched kernel ?
No you dont have to flash any patched kernel
• Does it support encrypted devices ?
Yes it does. You can use it on encrypted/non-encrypted device without any issues.
• Cool. But my secondary ROM shows phone not encrypted. Why ?
Multirom handles encryption transparently and hence the second ROM will never come to known that its encrypted. Never try to encrypt phone using secondary ROM. I repeat.. Never.
• Can I use a ROM newer than my primary ROM ?
Yes you can.
• Can I use a ROM older than my primary ROM ?
If you're encrypted.. No. Because of anti rollback protection in keymaster. But if you're not encrypted.. Yes. Since multirom build 20181211, you can flash older ROMs as well.
• What will happen to my other partitions if I flash MIUI as secondary ?
If you flash MIUI as secondary then all partitions except system,vendor and data will not be overwritten. However, if u want to use a new modem image (firmware.img) from a new miui build, u can use "Set radio.img" functionality in Multirom recovery and use the new firmware.img here.
But i will still recommend flashing a new MIUI to primary first to avoid any confusion.
• How do I flash a GSI ?
Its very simple. Just extract the .img file out of the gsi zip (this step is not needed if ur gsi provides an .img file directly for download). Then use this image with "GSI image" button when adding a ROM.
• Nice. Does Magisk work ?
Yes (as of magisk v17.1). For primary ROM, you *have* to flash magisk *first* and then multirom zip in case u want to use Magisk. Reversing the order will lead to magisk not working.
For secondary ROMs, Make sure you don't uncheck "System partition Mode" checkmark during adding secondary ROM. Then use "install zip" function in multirom recovery to flash magisk zip in the usual way. Whats more.. if u flash a GSI as secondary and ur primary ROM is rooted, ur GSI becomes automatically rooted with magisk.
• Can I flash a ROM on my USB drive ?
I don't expect it to work for now. However, it maybe fixed in future.
• Can i flash a ROM on my sdcard ?
I haven't tested this. It may or may not be possible.
• Can I set a PIN/pattern/password/fingerprint/face lock on my secondary ROM ?
Yes but if u do set, make sure your primary ROM doesnt have any kind of password set. Because even if u set the same password in secondary, u will be locked out of ur primary ROM. Flash this zip (https://drive.google.com/open?id=1tz2vq8vzVNs2s3NhcLp0UFAwJ2SyPgOL) to remove the security lock if u accidentally lock it.
You can use PIN/pattern/password on primary ROM alone though. Just do not set a PIN/pattern/password on both primary and secondary.
