If you use an Oreo ROM, you need Oreo firmware. If you use nougat, you need nougat firmware. Since you need both nougat and Oreo, no you can't because you can't have 2 different firmwares

Why MultiROM become "disable" if i do wipe dalvik& chache?
On MultiROM Manager i can see the ROMs but if i want boot any of them it does not work. Only the internal ROM works anymore.
If i do restart the rom selector screen does not pop up anymore...

Hi,
I am trying to boot(not flash) the unified recovery from the OP ... Its more than 5 minutes and its still saying ...
I have a pattern lock set on the device and the Security settings suggest that my device is Encrypted ... the whole idea of booting into this twrp recovery was to try to disable encryption a prerequisite for setting up multirom ... Unless i am supposed to use a generic twrp recovery file and not one that is specifically modified for multirom support ... the phone has turned pretty hot whilst the decryption is being attempted ?
------- edit --------
i just hard booted into the device ... awaiting help here ...

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"
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.

Enjoy!25The steps were already written but here you have.
I asume you are running Oxygen os.
1- Make a backup of all your internal storage (SD) data via usb MTP on PC.
2- Your device must have the bootloader unlocled, if not, search on xda how to do it. At this step you will need to install adb driver and fastbooot as described on the unlocking tutorial.
3- Reboot into bootloader and type on CMD on windows "fastboot format userdata"
4- Install multirom Twrp from fastboot " fastboot flash recovery multiromrecovery.img"
5- Reboot into twrp and copy all your backed up data via usb mtp to your phone.
5- Open cmd and type "adb shell chown -R media_rw:media_rw /data/media"
6- Flash supersu to avoid re-encryption by OOS
7 - Flash multirom.zip and reboot system. mr menu will appear, select Internal and leave oxegen to fully boot. Go to settings, fingerprint and security and check if it says device decrypted.
8- Reboot to twrp and Add the secondary rom from multirom menu in the twrp.
9- In multirom settings activate the option no exec warkarroun, also you can set in autoboot tab the option to boot always the rom you want.
9- Reboot and enjoy23Reserved

*Updated MultiROM Manager APK available here.
*FCs in secondaries should have been fixed in latest TWRP-MROM versions.17I created a flashable zip that could sovle the wrong pin/pattern error occurred after boot in both primary ROM and secondary ROM.
Flash this zip in recovery (For your secondary ROM, boot in TWRP>multirom>list rom>select your wrong-pin/pattern-ROM>install zip>flash this zip)
This zip will delete:
gatekeeper.password.key,
gatekeeper.pattern.key,
locksettings.db,
locksettings.db-shm,
locksettings.db-wal.
This will reset your lockscreen to "Slide", but your saved fingerprints will NOT be deleted. Just set a new security lockscreen after boot.
