Ahh okay. Thank you for the information. So I can drop creating logfiles etc ^_^
Sorry I didn't read many of the precedent posts, I've just seen the post above and threw spontaneously my two cents :)

BTW, I am currently creating a fix for the problems with the secondaries. I got it working so far, but need refactor and improve the current patch set to avoid one unsafe hack such that we can merge it in the upstream project after code review.

When the refactoring and improvement is done, I will make a preview release available. This would be around this weekend, so I'd advice anyone who wants to experiment with android-8.1 to wait a bit, such that you don't loose time.

A small heads-up: I will delay the experimental release with proper 8.1 support for 1-2 days since I was busy with the dtb implementation (see earlier posts). It is now properly implemented (IMHO).
Due to that I did not have time left to properly test other setups and stock roms. After doing so, I will make the experimental release such that those requiring 8.1 support badly can test this version on your own risk.

When the change is integrated upstream, and I 've integrated one or two more features that I planned since some time, the sable release will be done.

EDIT: Since stock roms are not booting (neither as primaries, nor secondaries), I will delay the experimental release further. I have no idea yet when this problem will be resolved: It could be small or a larger one.
Sorry for the inconvenience!

Could someone tell me if the latest experimental's TWRP, has support for F2FS?

Edit: Ahh, I see that there was problem and there is no MultiRom with Oreo support.
If testers are needed I would like to help that way (right now I have Nougat RR and would like to add Oreo RR as secondary)

New experimental build is up! You may need to use the manual installation depending on your primary rom (the apk in the download folder may be non-functional): https://diewald-net.com/files/public/MultiRom/sirius/experimental/

Since this is just an experimental release to support the current oreo 8.1 roms, here is just a short changelog:
- Compatibility enhancements with android oreo (SELinux policies and alike). (Mrom team)
- Support for FDT extraction and kernel appended DTBs (libbootimg).
- Support for removing "/system" partition entries from FDTs. (Oreo - Treble related change) --> Allows booting current 8.1 roms as secondaries.

Stock support has been tested - operational as primaries and secondaries.

NOTE: this is still an experimental release, so there may be bugs that I missed (short testing period). Nevertheless, the bugs occurring in the past have been tested and major functionality has been tested.

A stable release should follow in the upcoming weeks: Upstream integration of the FDT modification + adding some other fixes and background updates.

Thanks @akshay2shah for the support in testing

P.S.: Sorry for the confusion with the build from 3-4 days ago: Some bug was found that broke compatibility with some roms that is fixed in the linked experimental release.

Thanks for the offer :)

Please see the updated experimental release for Oreo support. You can help by reporting new bugs here consisting of steps to reproduce and the logs (especially the multirom log dumped to sdcard).

Thanks. Will check it, but alter. Could You tell me if there is F2FS support? It would make everything faster, as I wouldn't need to reformat the data.

Unfortunately, F2FS is not supported. It will come when I switch the build environment from an Omni-7.1-based to an Omni-8.1-based one (One of the next steps before the stable release).

However, you should be able to do a file-based backup, reformat, and move the data back.

I'd advise you to install the experimental version while you are on stock. Then, boot to recovery and copy or move the stock rom from the primary slot to the secondary (e.g., internal sdcard). After that, follow the normal instructions to install carbon (that will include a factory reset and wiping the /system partition). Please take care to tick the "Inject multirom" option when flashing Carbon. Also, please ensure that you flash gapps along with Carbon, as you will have permission problems if you flash them after booting Carbon up. After these steps, all should be setup as you described: Carbon as primary, stock as secondary.

Instructions for the single steps can be found in the first post, or in the github wiki of MultiRom.

Anyone have the zip file for manual installation ?

The app doesn't work anymore, i guess?


Please find the latest files in the attachment. The app does not work anymore since I have re-setup the server and did not install the package for the file service again. Given the age of the device, this is acceptable IMO.

    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.
    3. If you want to uninstall MultiROM, just flash the MultiROM uninstaller.
    4. Your device must not be encrypted.
    5. To all devs maintaing Stock-based ROMs: Feel free to use my patched stock kernels to add MultiROM support to your ROMs.
    6. 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. Install the MultiRom Manager app from the store and install the recovery and multirom.
    2. Reboot into MultiROM TWRP and flash the MultiROM installer --> Sould be done automatically.
    3. Make sure you are on a Rom compatible with one of these kernels and flash it
    4. In order to boot a secondary rom you MUST enable the "kexec workaround" option in the MultiRom settings found in the recovery.
    5. That's it. You can now go to "MultiROM menu" (Top right corner in the recovery) to start flashing other ROMs.

    Alternative installation method (if installation via the above method fails)
    1. Download the files named multirom-<date>.zip and recovery-<date>.img from here.
    2. You should use md5sum to validate the downloaded files using the provided xyz.md5 files in the same download location.
    3. Copy the files to the sdcard of your device.
    4. Use "adb shell" to open a shell on the device and use "su" to obtain root rights (adb must be set up on your computer, instructions are found on xda).
    5. Adjust the following command and enter it in the shell: "dd if=/sdcard/recovery-<date>.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel"
    6. Reboot into recovery (shutdown, then VolDown + Power).
    7. Flash the multirom zip from the sdcard.
    8. Enjoy.



    Adding ROMs
    Go to recovery, select "MultiROM menu" (Top right corner in the recovery) -> Add ROM. Select the ROM's zip file and confirm.​



    Using USB 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 menu" (Top right corner in the recovery) in recovery and do Inject curr. boot sector. if it is not done directly during installation of the Rom.
    2. Secondary Android ROMs
    If you want to change the ROM, delete it and add new one. To update ROM, follow these steps:
    • Go to "MultiROM menu" (Top right corner in the recovery) -> List ROMs and select the ROM you want to update.
    • Select "Flash ZIP" and flash ROM's ZIP file.

    Install a stock rom as secondary

    This only works if you are using MultiRom version 33c or larger (excluding 33x-z).

    1. Existing primary stock rom
    Use these instructions if you plan to move an existing stock rom installed as primary. This guide assumes that multirom recovery is properly installed.
    • Shutdown the device.
    • Start the device into multirom recovery (VolDown + Power).
    • MAKE A BACKUP!
    • Go to "MultiROM menu" (Top right corner in the recovery) in recovery and tap "Swap roms".
    • Select the option "Copy primary rom to secondary/internal" and start the operation.
    • Wait until the operation finishes and flash your desired rom. (Alternatively you can also use any secondary rom to be the primary rom using the "Swap option" mentioned above.
    • Reboot.

    2. Fresh stock installation
    Use these instructions if you do not have a stock rom installed as primary. This guide assumes that multirom recovery is properly installed.
    • Shutdown the device.
    • Start the device into multirom recovery (VolDown + Power).
    • MAKE A BACKUP!
    • Install the stock rom via an install zip of via an FTF. NOTE: For the FTF method you need to shutdown the device and boot into download mode (VolDown pressed while connecting the USB cable; cable connected to the PC). Use for instance flashtool to flash ONLY the kernel, system, and cache image. In addition, you MUST select "Wipe apps_log"!
    • When the device reboots, let it boot up and finish the first time setup procedure.
    • Shutdown the device.
    • Start the device into multirom recovery (VolDown + Power).
    • Go to "MultiROM menu" (Top right corner in the recovery) in recovery and tap "Swap roms".
    • Select the option "Copy primary rom to secondary/internal" and start the operation.
    • Wait until the operation finishes and flash your desired rom. (Alternatively you can also use any secondary rom to be the primary rom using the "Swap option" mentioned above.
    • Reboot.

    I just started a build on my finally completed jenkins setup. Be prepared for TWRP 2.8.5 and MultiROM v31x. Build should be up in ~15 min, and MultiROMMgr should be updated automatically too.
    Edit: It's up :p

    Regards

    It appears like I fixed MultiROM (at least on the Z3 Compact) yesterday (both, graphics and booting secondary Roms with a different boot.img) . Going to do some more tests with it today and then publish it for Z3C followed by pushing an updated Version for Z2 and Z3. Sorry for letting you guys wait that long.
