Introduction

MultiROM is one-of-a-kind multi-boot mod for Htc One (m7). 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




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

MultiROM has 3 parts you need to install:

  • MultiROM (multirom-YYYYMMDD-vXX-UNOFFICIAL-m7.zip) - download the ZIP file from second post and flash it in recovery.
  • Modified recovery (TWRP_multirom_m7_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.​

Downloads

1. Main downloads

MultiROM: multirom-20141028-v29-UNOFFICIAL-m7.zip
Modified recovery (based on TWRP): TWRP_multirom_m7_20141028.img
Working on it MultiROM Manager Android app: Google Play or link to APK

You need to have kernel with kexec-hardboot patch only in your primary ROM!

2. third-party kernels with kexec-hardboot patch

ElementalX - http://forum.xda-developers.com/showthread.php?t=2249774
teaMSeven - http://forum.xda-developers.com/showthread.php?t=2307371

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.

I have any problem with TWRP, specially for you have i downloaded and flashed recovery from my post. Try flash it again, or flash clean twrp and then flash mrom-twrp

Unfortunately it still doesn't work, I tried flashing the Official TWRP, booting into it and then flashing your MultiROM TWRP but it didnt work

It is possible install Miui as secondary Rom ? Thanks

Enviado desde mi HTC One mediante Tapatalk

Everything I've tried works including miui (I think too many to remember). Only issues I've had is with ROMs that use aroma. To install these as secondary.....

Nandroid original primary
Flash new Rom as primary
Boot new Rom
Nandroid new primary
Restore original primary
Install new primary as secondary from nandroid

Never had to change recovery either.

Always back primary when trying a new secondary.

    well i guess, i got a bit greedy, and wanted to make (still do) a universal build for the M7s, but since the "by-name" support is not [entirely] there, i'll just leave this for whoever wants to try/use it

    @mitchst2 has done all / much of the testing, thanks :D

    you need to unzip the file, and you'll get three files:
    Code:
    1) recovery-multirom-20150529-v32dirty-UNOFFICIAL-m7.img
    
    2) multirom-20150529-v32dirty-UNOFFICIAL-m7.zip
    
    3) Fix_filecontexts_for_MultiROM_v2.zip


    1) MultiROM TWRP recovery ("fastboot flash recovery recovery-multirom-20150529-v32dirty-UNOFFICIAL-m7.img")

    2) multirom-20150529-v32dirty-UNOFFICIAL-m7.zip -> install using MultiROM TWRP

    3) Fix_filecontexts_for_MultiROM_v2.zip -> install using MultiROM TWRP after flashing anything

    once i manage to get things done properly, i'll update... for now, this should work fine
    PS: i'm only calling it "dirty" cause i had to build it too many times

    this is only for m7_u and m7_ul models

    Who wants an update?

    1- recovery updated to universal build
    2- by name "hack" added and seems to work... I can't test, but should now work on Verizon and Sprint as well
    3- file contexts fix built in
    4- layout version fix, built in
    5- hmm, what was five

    How many ROMs have you installed?! And is this about installing lollipop as secondary?
    Insane, but totally awesome, i'm trying to boot 4 roms hope it works :D
    yep, both KK and LP ROMs are running fine.

    Ok so here goes, exactly what I've done step by step, hope this helps (note: I had completely wiped everything from my phone due to RUUing & formatting it, so nothing was there)


    update firmware to 7.15.401.1
    http://pastebin.com/HiA36mBZ


    installed ViperOne 7.0.2 using regular TWRP (no particular reason I chose that ROM, just happened to be in the right folder)
    installed ElementalX 18.0 using regular TWRP
    (I could have used MultiROM TWRP, but used the regular one cause I had it there already)


    time to MultiROM:
    flash recovery: TWRP_multirom_m7_20141028

    Install MultiROM:
    inside TWRP MultiROM: 1st install multirom-20141005-v28b-UNOFFICIAL-m7
    then install multirom-20141028-v29-UNOFFICIAL-m7


    Install DirtyUnicorns 9:
    Now since the ROM I was installing as secondary (Dirty Unicorns 9) has "block_image_update" in the installer-script, it won't flash to secondary, so instead, I first moved my primary (ViperOne) out of there:
    MultiROM -> Swap ROMs -> Move primary to secondary (obviously I also changed the name when moving it)

    so now I have no primary (only ElementalX kernel), I made a backup of that and called it "Base 0" (which i can restore any-time to get MultiROM to boot up)

    then installed DU 9 to Primary (do not inject MultiROM) -> Move to Secondary -> restore "Base0" to Primary -> bootup and it works :D
    ViperOne is also still as a secondary and also boots fine.
    and as primary, nothing, just the "Base 0" backup of ElementalX 18.0



    here are all the ROMs, I've tested all successfully; installation method is the number in brackets

    Secondaries: HTC Sense 6 ROMs
    (1)**KK** ARHD Sense 82.0
    (1)**KK** ViperOne 7.0.2
    (1)**LP** ARHD Sense 90.1
    (1)**LP** MaximusHD 50.0
    (3)**LP** InsertCoin 6.0.3

    Secondaries: GooglePlayEdition ROMs
    (1)**KK** ARHD GPE 6.1
    (1)**LP** Google-Plus-Edition-LP_m7_v2.00_020315
    (1)**LP** SkyDragon+GPE501+M7+V6.0.0

    Secondaries: AOSP based ROMs
    (1)**KK** SlimKat 9.0 (including gapps)
    (2)**LP** LiquidSmooth 4.0 (including gapps)
    (2)**LP** Dirty Unicorns 9.0 (including gapps)

    Secondaries: Other ROMs
    (1)**** MIUI (miui_One_4.8.8_5cf931dfdb_4.2)




    Installation methods:
    (1) -> directly to Secondary -> works fine

    (2) installer-script contains "block_image_update" so flash to Primary (do not inject MultiROM) -> Move to Secondary -> restore "Base0" to Primary -> works fine

    (3) -> directly to secondary -> boots -> Android is upgrading -> then it reboots and gets stuck :(
    but since it got to Android is upgrading (but not showing any adb logcat activity during bootup), I figured maybe something with the kernel is weird-ish, so I just flashed "ElementalX-m7-19.2-Sense" into the secondary partition -> works fine :)
    (it could have been something else, but I didnt bother testing further :rolleyes:)

    EDIT: I believe the problem was due to the "restorecon -FR /data/media" as described on page 61
    you should flash the Fix File Contexts zip from post 610


    Hints and Debugging Procedures:
    • do not reboot using the installer, go back to BACKUP and check the primary partitions are unaffected (click Refresh Sizes, to update)
    • make sure the ROM installed properly by going to MultiROM -> List ROMs -> (select the ROM) -> Backup -> Refresh Sizes then make sure the partition sizes make sense (eg if you see a zero size /system partition, it's not going to boot)
    • run a "adb logcat" when you see the ROMs bootanimation, it will start with --waiting for device--, then after a few minutes begin dumping the log, remember some of these ROMs take quite a long time to boot up, easily approaching 20mins (maybe even longer)
      (Note: in some ROMs the adb logcat option could disabled/not authorized, so dont rely on it 100%)
    • on one or two occasions had to go back to recovery -> MultiROM -> List ROMs -> (select the ROM) -> Wipe /cache and dalvik

    If you want me to test any particular ROM, let me know, but so far all of them have worked for me :victory: :highfive:

    EDIT: right now I have all 12 of the above ROMs installed as secondaries, no primary, and they all boot fine
    but i only have 3.5GB of storage left :p
