How to modify twrp to manage multiroms?:confused:
Click to expand...

Just flash the MultiROM recovery image using dd :)

Open up a terminal/adb shell and do the following:

Code: 
su
dd if=/<path-to-the-recoveryimage> of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel

So let's assume you download TWRP_multirom_20141208-00.img and place it in the root of your sdcard:

Code: 
dd if=/sdcard/TWRP_multirom_20141208-00.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel

Hi Olivier.
I found your Omni 5.1 builds :eek:
Can I run MultiRom on Omni 5.1 base?
And which TWRP do I have to flash, the one in multirom folder or the one in twrp folder?


Edit:
So I tried it and found it does not work.
Omni 5.1 builds work great though (tested build 20150411).
Going back to Omni KK, I love MultiRom ;)

Thanks for your work Olivier!

    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. 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.
    3. 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.
    4. If you want to uninstall MultiROM, just flash the MultiROM uninstaller.
    5. 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).
    6. This is still a work in progress. Don't ask for ETAs please.
    7. Your device must not be encrypted.
    8. To all devs maintaing Stock-based ROMs: Feel free to use my patched stock kernel to add MultiROM support to your ROMs.
    9. 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 OmniROM
    2. Flash my modified kernel
    3. Flash the MultiROM installer
    4. 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.

    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.
