MultiROM is one-of-a-kind multi-boot mod for Oneplus 3. 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.

Note 1: Your device must not be encrypted (hint: if you don't know what it is, then it is encrypted).

MultiROM has 2 parts you need to install:
  • Modified recovery - You cand download the unified IMG file here, or specific for OP3 from second post and use fastboot or TWRP or Flashify app to flash it.
  • MultiROM - download the unified ZIP file here, or specific for OP3 from second post and flash it in recovery.
  • Go into TWRP MultiRom settings and check "Enable No-KEXEC Workaround"
Your current rom will not be erased by the installation.
Download links for specific OP3 version are in the second post.


WORKAROUND for FCs
If you get FC's in your secondary, edit build.prop in that secondary's /system dir and set:

Code:
#ro.sys.sdcardfs=true
...to comment the line (don't delete, don't set to false).

Don't boot before editing this line (flash secondary, edit and then boot).

You can edit in your primary if you are rooted, looking into:

Code:
/sdcard/multirom/roms/<your_sec_rom>/system/build.prop
*You can also try using multiromfix.zip, available in this post, thx to @Startrek852 (to disable sdcardfs support in that secondary).



Adding ROMs
1. Android
Go to recovery, select MultiROM -> Add ROM. Select the ROM's zip file and confirm. As for the space, clean installation of stock 6.x after first boot takes 900+mb 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 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 MultiROM -> List ROMs and select the ROM you want to update.
  • Select "Flash ZIP" and flash ROM's ZIP file.

Thanks a lot to Tasssadar for creating this awesome utility.

Hey, booted into a secondary ROM and now Oxygen is throwing an "incorrect pattern" error. I remember there were some files to delete to fix this, but I can't remember which ones. (Maybe add it to the OP to prevent confusion?) Thanks for your time!

I am unable to boot OxygenOs, what process did you folowed?

And for the incorrect patern just go to twrp- file manager, navigate into /data/system and delete the files:

password.key
pattern.key
locksettings.db-wal
locksettings.db-shm
locksettings.db

Thanks so much! By not being able to boot oxygen, do you mean as secondary or as primary? It must be unencrypted. Beyond that I don't know. It might be harder as secondary, I don't know if it would encrypt itself again.

I can boot into oxygen when it's the primary os through the given method, but it does take a few seconds of black before the boot animation shows.

My phone is decrypted and oxygen as primary. But i cant boot secondary roms, it always shows me the boot menu over and over.. when i select secondaries to boot.
I was able to boot only one time a sacondary rom. Must be there something am doing wrong.

Huh. Be sure you checked the custom recovery setting related to kexec, I don't think that is supported on our device. Other than that, I'm as clueless as you :D

Huge thanks for this port @martinusbe

FYI, I've tried all these roms as secondary, using the K-exec workaround. All are working very fine (device decrypted)
  • Beanstalk
  • ResurrectionRemix
  • Slim
  • Tipsy
  • Bliss

Thank you !

Edit : Just tried the MM apk, and it does not see the MM recovery, even tho it's already installed
Have you been in touch with Tassadar to have it official ?
