MultiROM is a one-of-a-kind multi-boot mod. It can boot any Android ROM as well as other systems like Ubuntu Touch, once they are ported to that device. Besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from USB drive attached via OTG cable
You can also watch a video which shows it in action.
WARNING
It is dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.
IMPORTANT
I'm not responsible for anything, you do all this on your own risk.
Many Stock-based ROMs will fail to install because their boot.imgs cannot be unpacked using normal tools or use unsupported compressions. Please contact me in that case, but do note I can't add support for each Stock-based ROM out here.
Once you have flashed and set up MultiROM, don't flash another boot.img using fastboot or normally. Always go to "Advanced -> MultiROM" to flash ROMs/kernels or other mods.
If you want to uninstall MultiROM, just flash the MultiROM uninstaller.
Don't try to flash ROMs with Stock boot.imgs (supported by LBs). They need special unpacking tools and are therefore currently not supported. I haven't yet tried flashing other Stock ROMs. Besides, I have configured MultiROM to only support boot.imgs that use the 2 stage boot method (boot.imgs with recovery ramdisks inside).
This is still a work in progress. Don't ask for ETAs please.
Your device must not be encrypted.
To all devs maintaing Stock-based ROMs: Feel free to use my patched stock kernel to add MultiROM support to your ROMs.
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
Make sure you are on OmniROM
Flash my modified kernel
Flash the MultiROM installer
That's it. You can now go to "Advanced -> MultiROM" to start flashing other ROMs.
Adding ROMs
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.
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.

Yes, probably.

Thanks for this, it gave new life to my ZL! Multiboot rocks! I've managed to run Omni, CM11 and Carbon KK , so far so good. Are you also by chance doing a stock kernel for ZL that works with multirom, just like your stock kernel in Z? Hope you could also create stock kernel for ZL, really appreciate it. Thanks in advance.

What about adding MultiRom support to 4.4.4 stock kernel? Should we wait for new kernel source release from Sony?

Will this work, it is based on stock .283 but with added features -
http://www.mediafire.com/download/1bf5bhjbtbvxhnk/Advanced_stock+kernel_for_KK_10.5.1.A.0.283.zip
Features:
Dual recovery - CWM Philz Touch 6.48.4/TWRP 2.7.1.0 (vol up - CWM / vol down - TWRP)
Init.d suport
Debugging enabled by default
Disable debugging notification icon in the status bar
Kernel insecure (ro.secure=0)
Kernel taken from here - http://forum.xda-developers.com/xpe...ed-stock-kernel-kitkat-4-4-t2873475#undefined
I've also informed the developer if he is ok with it being modified to have kexec patch.

^^ probably not, as multirom needs w/ kexec modification, which isn't listed above.
Did someone manage to boot ubuntu ( http://forum.xda-developers.com/showthread.php?t=2434585) in multirom? How?
Could we have native ubuntu touch support with the next version, please?

Thank you.
So could this kernel be used to start stock rom 10.5.1.A.0.283 as primary rom?

Hey guys, a new update is up. There have been many changes, you can now install ROM to the external sdcard. Enjoy!

thanks for this! im using latest update and also lightning kernel and CM11 as primary rom, it works good! im thinking for stock kernel to work as secondary rom, we have to modify the mount points? edit the ramdisk? just trying to understand before i try to do it on my own. really wanted to have working CM11 as primary and stock as secondary. thanks again

Thanks @olivier. Ext SD support is great.
I was wondering if we will get stock rom support as primary in the future.

You can do the following (once my stock-based kernel is available): Install a stock rom as primary, back it up and restore it as secondary ROM.

MultiROM v29x is up!
As for the Stock-based kernel: I have decided not to support Stock ROMs officially, but you can always use the lightning kernel by nikhil18 to have a Stock-based kernel with kexec-hardboot support.

General Informations about Kexec are coming here soon.

I will test it when i come home and report the result.
Edit: all is stable only Multirom menu needed to be fixed but that you have reported, thanks
Now i can use stock as daily driver and cm12 to see the progress. many thanks.

Whaaaaaaat. This is amazing! Thanks for your work, keep at it! I will surely use the multirom a bit later, when some more roms like PA are avaiable.

Wow great work! A noob question but one assumes that I would not be able to have one rom on 4.4.4 and another on Lollipop 5.0 due to the fact the base Kernel AndroPlus is designed for 4.4.4 or does Multi Rom allow 2 different Kernels? Thanks in Advance.

It actually is possible. The Base Kernel is patched to be kexec-hardboot compatible. This means it is able to load other kernel to the RAM and run them from there. The host kernel is just a middleman loading the kernel to the RAM, it is not doing anything else which means it is not affecting the secondarys kernel at all.

I used to do this on Nexus 5, loading 4.4.4 with kexec kernel and then 5.0 preview as the other rom and it worked, so it should be possible here as well.

yup, leo is the Z3's codename. Sirius is Z2 and n801x is my Samsung Galaxy Note 10.1. Guess thats what happens when CM breaks the naming law and calling it just z3..

see there we go with the Leo thingy again Seems like I need to edit the device tree to make the Phone in Recovery appear as some D**** device instead of Leo. Will do tomorrow and release a update. /dev/block/mmcblk1p1 is your physical SD Card (it is formatted as exFat which is what TWRP is displaying).

change updater-script to leo. this should help.

Yeah when I saw that in the log I figured it was incorrectly detecting the device. I look forward to the update. I also guess that's why the Multirom app does not work?

Ill try this. I cant see the installation progress / logs in the cm recovery included in the cm12 package

Can it work on C1904/C2004?
Hi. Great job with the kernel dev. Have been waiting for an OC kernel for CM12. Problem is, I have a C2004 with C1904 firmware cross-flashed on it, on top of which i have CM-12 based Resurrection Remix ROM running. Will this kernel be able to run on my device, since you have mentioned only C1905 in your post?

No. This is not multirom, but MultiRecovery. (you can have TWRP, Philz, CWM and CM Recoveryes in one kernel)
if you mean cm11_addon cm12_addon and stock_addon, you can use only one of this.
i dont want to upload new kernel versions for both, so you must install kernel first. and then one of addons.
if you flash more of addons, it will use last flashed addon.
MultiRom is another project by alvinhochun
but i want implement it in my MultiRecovery kernel in future.
But, when you want, you can extract ramdisk from kernels, replace recovery cpio´s in /system/kernel/recovery
and now you can boot 4 different kernels. but without editing this kernels you can use kenrel only for rom located in /system.
only cm11, cm12 and stock rom are supported.
but if you want boot "unsupported" rom with this kernel, you must unpack ramdisk.cpio from rom kernel, and then move it in /system/boot.cpio.
cm11_addon, cm12_addon and stock_addon flashes only thit boot.cpio. so you can support any ramdisk you want.
but you will not have OC.

I copied my fstab.qcom and init.qcom.rc to /patch folder but it didn't replace the original files
I found this code in your init.sh:
Code:
busybox cp /system/kernel/patch /
And I think it should be changed to
Code:
busybox cp /system/kernel/patch/* /
We should also have an option to run user's script before system boot. I added this line:
Code:
exec /system/kernel/script.sh

Thanx. I have not trayed patch function yet.
I will change this in next version.

i think using -R is allowed in busybox. or not? cp -r /system/kernel/patch/* /

Which rom are you using? i have same problem with Resurrection Remix 5.3.3.
Try cm-12-20150123-UNOFFICIAL-nicki by PecanCM´s CM12
Now i am using Resurrection Remix 5.3.3, with my kernel, but i have copyred ramdisk from rom into /system/kernel/boot.cpio.
it is solution too. but you will have not overclock.

MultiROM is a one-of-a-kind multi-boot mod. It can boot any Android ROM as well as other systems like Ubuntu Touch, once they are ported to that device. Besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from USB drive attached via OTG cable
You can also watch a video which shows it in action.
WARNING
It is dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.
IMPORTANT
1. I'm not responsible for anything, you do all this on your own risk.
2. Once you have flashed and set up MultiROM, don't flash another boot.img using fastboot or normally. Always go to "Advanced -> MultiROM" to flash ROMs/kernels or other mods.
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.
6. To all devs maintaing Stock-based ROMs: Feel free to use my patched stock kernels to add MultiROM support to your ROMs.
7. When booting another ROM, you'll notice that in some cases, you can enter the recovery of the boot.img of the ROM. Please don't use it, flash everything using MultiROM TWRP.INSTALLATION
1. Make sure you are on a rom compatible with these kernels.
2. Flash the required kernel zip.
3. Flash MultiROM_TWRP-xx-xx-xxxx.img on fota partition.
4. Flash MultiRom_xx-xx-xxxx-v31x.zip
5. Done1Adding ROMs
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.
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 Rom
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.

Superb job @aweosomeabhijeet
And u can even add XMD in thread title bcoz it even works on it.. I am XMD user.. It's working well

@aweosomeabhijeet, to prevent compatibility issues that may occur it will be better to use boot image repacking script (e.g. with unpackbootimg and mkbootimg utilities) that will inject new zImage (it is kernel file in your out/target/product/nicki folder) in boot image than flashing raw boot.img, so ramdisk will not be overridden (as far as I understand we don't need changes in ramdisk for kexec, do we? and even if we do, it will be better to replaced only changed files, not the whole ramdisk). Noel Macwan uses that thing in his kernels, I used his script as base for my old injecting CWM/TWRP script.
---------- Post added at 21:26 ---------- Previous post was at 20:57 ----------
BTW, what kernel sources did you use for your kexec-patched kernel? Are they Sony stock ones? Aren't they from CM12.1 repo?

SUCCESS
so today i successfully flashed 3 roms on in XMD which run smoothly..the only problem i faced is patience when flashed through recovery i in usbdisk (which is obvious)..so now i dont need to wipe or format my primary rom in oder to test other builds..fabulous job @aweosomeabhijeet

Indeed a very good idea, but I am worried about pure stock users. I think the script won't work, though I haven't tried.
They are from CM repo only, I am fixing some issues will push changes to my fork of CM kernel.

We can make different zip for pure stock and for custom ROMs. But is now MR working on stock? Doesn't it have split screen bug? If yes, you should try using custom recovery graphics, and I am not familiar to C, so can't help. And BTW does stock work with CM kernel? I very doubt it. Even if it will work with stock ramdisk and CM zImage (which I doubt too, as CM kernel is built on CAF sources with some changes from stock kernel if I'm not wrong), it surely won't work with full CM boot image, so repacking script will be the best solution (I can even make it for you today if changes in initrd are not needed). And if stock will boot with CM zImage we will not have screen split bug anymore, and script also should work even with stock (as the command line is the same, and even if not, we can read it from unpackbootimg output by using `cat *.img-cmdline` for command line value in script). But building different kernels for stock and custom ROMs (all custom ROMs for our device share the same kernel source, difference is only in ramdisk, you can even boot CM11 with CM12.1 kernel if you will keep CM11's ramdisk) is better solution.

Actually you are getting it wrong!
1. We would not have any screen shift bug
2. Every ROM we boot from multirom can use it's own kernel irrespective of what kernel is installed in the device. (That's the benefit of kexec-hardboot)
3. I have a better idea for maintaing stock and all. Will upload new zip soon. I would like to use parts of your script if you don't mind.

BTW, why didn't you git clone kernel repository (it would save commit history and make your fork git-compatible with original) and then apply your patches? Otherwise, it will be harder to support your patched kernel, as it has another commit history and you if I am not wrong will not be able to merge and cherry-pick commits from CM kernel to your kernel, you will have to do it manually, which is quite annoying, or leave your kernel unupdated in future.

Seems that we misunderstand each other. I talk about using other ROMs as primary, not only CM. We can do this by using kexec-ed kernel. I just offer you another method installing it, which will keep original ramdisk (if kexec doesn't need changes in it) and only replace kernel itself (zImage only, not boot image).
And I don't mind using parts of this script.

I know it. I have forked the repo and currently cloning. It's just in beta status and is just for giving details about the patch. I'll soon be on CM kernel and would merge all its commits and kernel would be updated always.
Don't you worry about it, I have all in mind. It takes time, I am free majorly on weekends so I won't rush on things.
I understand this and I have already made installer zip which does exactly what you are trying to tell, it uses parts of your script to replace just zImage and not whole boot.img. I still have something better coming. Just wait for few days.

Introduction
MultiROM is one-of-a-kind multi-boot mod for Nexus 5. 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
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:
MultiROM (multirom-YYYYMMDD-vXX-armani.zip) - download the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_multirom_armani_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.
Currently dual booting MIUI isn't working! So DO NOT try to dual boot MIUI with LP/KK ROMs.
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 5.0 after first boot (with dalvik cache generated and connected to google account) takes about 676mb of space.
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.
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.

3. Uninstaller
MultiROM 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
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.
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.
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 you port MultiROM to device X?
No, probably. I won't port MultiROM to any device I don't own, because it is very difficult to provide the level of support I want to provide if I can't test things myself, as proven by the Nexus 4 port. I'd like to support more devices, but it is also very unsatisfying to work on code for device I don't have - I invest hours upon hours of time for free into it, and then I can't even see it running on the device, so...why..bother..?
I'll probably keep buying Nexus devices and keep porting MultiROM to those myself, but I can't buy every single device - I'm still a student, all my existing devices were bought using some kind of money grant or donations from users.
But, you can port it yourself, the wiki should give you at least some idea how to do that: https://github.com/Tasssadar/multirom/wiki/Porting-MultiROM

You'll see multirom menu to choose the system you want to boot into.

Introduction
MultiROM is one-of-a-kind multi-boot mod for Xperia Z1. 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. 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
* 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 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
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:
MultiROM (multirom_vXX_n7-signed.zip) - download the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_multirom_n7_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. 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.
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.
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.

Have you managed to get it to work? I've tried to port it myself, and got the recovery to work, but it always fails to boot any secondary ROM for me. Did you use the XperiaMultiRom sources?

Yes I did. Multirom works, but as soon as I select a second ROMit tells me the kernel doesn't have a kexec patch. I am trying to build it with the android 5.1 sources this time (used 6.0 for this build).
Edit: Same result with the 5.1 sources. I've provided the multirom.log in the main post. Maybe someone with more experience could take a look at it.

Are you using a 5.1 ROM with kexec as your primary ROM (I assume you already are)? I had similar issues with booting secondary ROMs, http://pastebin.com/mkYhMrBJ is my log. What value of kexec_mem_min are you using? Also, if you can't boot into a secondary ROM, what part of multirom is actually working for you?

Yes, a 5.1 stock ROM with kexec as my primary ROM. The value I am using for kexec_mem_min is 0x25000000. The part of multirom that works is the part that allows me to change settings and install/manage ROM's.

So you mean the recovery? I've got that working too, seems like we're both stuck at the same point...unfortunately we don't have the sources of the old multirom v30x.

Is it only me? I cannot find download links for your version

Its not even working yet. This is more of a placeholder thread (which technically isn't allowed by XDA rules), but it also can be considered a development thread. I suggest OP add dev to the title.

As soon as I saw the MultiROM selection screen I posted it. But that might have been a bit too quick as I did not try loading a secondary rom yet . I have added [DEV] to the title.

That was a little premature.
Can you share your device tree? I would like to take a look. Also, did you try using the new Multirom recovery to flash the old v30 and see if it boots? In that case, we only need to port kexec to MM to have dual boot. (not an easy task either).
I've also contacted Tasssadar for info on what the logs (mine at least) mean, but he hasn't responded.

MultiROM v30 boots fine.
I used Sony's device tree
mr_init_devices.c
Everything from BoardConfig.mk after line 41.
I could give porting kexec to MM a shot when I have some spare time.

Hi. I experienced a problem entering the recovery. My device stuck at the Sony symbol displayed an the orange LED when I try to enter. Before I updated my recovery I used the one from v30 thread without any problems. Any idea where the problem is?
Thanks in advance!
