[Q] Nexus 5 MultiROM lost kexec-hardboot

I've installed MultiROM on my Nexus 5 device and i've had it for a while and never had a problem with it. Until now. I decided to wanted to have my OmniROM in place of CM11 and I accidentally copied the secondary to primary slot in TWRP. Now whenever I try to boot up into CM11, it gives me the error code "Kexec-hardboot support required to boot this ROM. Use kernel with kexec-hardboot support." I have no idea what this mean and I'd really like for it to get fixed asap. If you can help, please do asap. Thanks in advance!

I know it's been a while, but for anybody who may need this...
What happens is that MultiROM needs the primary ROM to have a kernel patched with kexec to work its magic. Most stock and quite a few custom ROM kernels don't have it, so it needs to be installed.
Fortunately, the MultiROM application (available here as an apk or in the Play Store) is here to automate all this. Your device must be rooted for it to work, but if you've already used it once I guess you know how to do it again (note OmniROM isn't rooted by default).
If anything, please refer to MultiROM original post. Most of its workings are explained there. To quote it:

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.

[Guide] Multi Boot Note 3 (Updated 24/07/2015)​
*** Hi Guys i no longer have a note 3 so i cant do any testing but our team member is here to give support for you all and even im here to give support except testing. please contact @[email protected] and @djnim for support.***
I am using this on SM-N9005 Snapdragon Variant of the Note 3; I believe this will work with other Note 3 Variants as well. Few of them are already tested and you can find them below. Others who have different variants which are not tested can try this and update us, and we will be here to help you out if you are ready to try this out.
@chenxiaolong is the one who made this happen to our beloved Note 3
Main advantage of this is you can try any new rom with out loosing or having any kind of trouble with your existing rom. This mod will not change anything in your primary rom, so any time you can go back to your normal state.

Requirements
* Read the full guide before Starting.
* Backup your phone if you are doing this first time. (Full Nandroid backup recommended for the new comers and it’s also recommended to others who don’t know what they are doing exactly even if they have multi booted several times)
* Rooted Note 3 with custom recovery (preferred TWRP or philz).
* free space in your internal SD (for example a Cm based roms take up to 2.5GB to 3.5GB and a TW roms take up to 5GB or more.)
* If you face any trouble please read the FAQ before doing something or asking for help. And if you want help please provide as much as details(device, roms, etc.) you can.
*
Instruction:
1.Download your desired Rom which you want to use for multi booting and the mods, addons, gapps, Kernel etc for the same. Keep the files in your internal memory.
2. Download the most recent snapshot release of Dual Boot Patcher and install it on your Note 3.
3. Open Dual Boot Patcher and grant SU permission. Then go to ROMS and you will see your Primary rom, press the 3dotmenu key and click "set kernel". If it fail to set kernal please read the FAQ.
4. Then In Dual Boot Patcher go to Patch Zip File and Choose hlte for snapdragon variant and ha3g for Exynos veriant (Samsung Galaxy Note 3) from the drop down menu.
5. In the second drop down menu select "Data Slot".
6. Below that you have to enter the ID of the secondary rom.(Example 1, 2, 3, etc. - it will take it as /data/multiboot/data-slot-1)
7.Now tap on the below button to choose the ROM's, Gapps, Kernel and mods to patch them and make them perfect for Multi booting.
8. Always remember to keep same slot ID for the Gapps, kernels and mods same as the rom. (Example: if you want to flash the gapps/kernel to the data-slot-1 rom then you have to select the same ID that’s 1 or if you want to flash the gapps/kernel to the data-slot-2 rom then you have to select the same ID that’s 2.)
9. When selecting the files except cm rom zip there will be a “preset” drop down menu, from that you have to select according to the file you are going to patch. (Examp: for roms, kernels, mods, addons – custom; for gapps – Google_Apps; for Su zip – other/SuperSu; For xposed-Other/Xposed)
10. Now press the tap to begin patching button to patch the file. And you will get a new patched zip file in the same location.
11. Now Boot into custom recovery and flash the new patched file and reboot.
12. And your device will boot into New Rom.
13.Install the Dual Boot Patcher app and set the kernel for your second ROM as well.
14. To switch between roms
•Open Dual Boot Patcher app/roms and click on primary or secondary rom as you like and reboot.
•Or Use Swap Roms to switch between Roms.
* Important things to keep in mind: while installing a rom or mod with Aroma installer don't reboot directly from the aroma.
You have to always uncheck the last option to reboot in aroma and click finish. So it can finish the final steps for multi booting.
And if you miss that it will only reboot to recovery. To boot back you have to flash your primary rom kernel or re-flash the patched rom.
Never update a secondary rom through OTA Update.
*. For other devices:
1. You have to download and install X-plore File Manager (which I am using) from play store.
2. Open X-plore File Manager from app drawer and navigate to the patched zip file and open it.
3. Now you will see a folder named multiboot inside that you will find info.prop, now open info.prop with the text editor which comes with the x-plore file manager.
• And then find and change mbtool.installer.ignore-codename=false to mbtool.installer.ignore-codename=true
Revert
To revert back or if you face any problem just flash my Multi Boot cleaner.zip which will wipe all the installation files from \system and restore the primary rom kernel.
As a backup keep a copy of your kernel flashable zip file.
FAQ
1. I can't set the primary rom kernel in xyz rom. And I can’t switch to other rom in primary rom.
Ans. Just download the set kernel fix as per your model and flash it in the recovery.
The above fix only work for primary rom. If you have trouble with any other roms just add ro.patcher.device=hlte(for other models add your model instead of hlte) to the bottom of build.prop of that rom and you are good to go.
If you don’t know how to do that just pm me and I will make a flash able zip to add it to your secondary rom.
if the above didnt work Read this post please
2. App sharing?
Ans. Until now no luck. (Still under testing)
3. This rom can’t be patched.
Ans. some roms are not supported its known, if the Dev have time may be he will consider including them.

1. First of all have you grant super user permission for Dual Boot Patcher. If not just reboot and try again.
2. Do you have enough space in your sdcard (internal) for the backup of the kernel.
3. Just check if there is sdcard/multiboot/primary/boot.img is their.
4. Try the 8.0.0.r1119.g9c51715 version of dual boot patcher if the above didn’t help.

Here we go! I have complete dual Boot on my Note 3! It's awesome! My first Rom is Aryamod 5.3 and my Second Rom is temasek unoffical cm rom! Thanks to the Developers for your great Roms! And now Thanks to you 54NJ41! Your tutorial is great! I wait over 1 year for dual Boot on my Note 3 and now I have it!

does anyone knows how i could get more system partition space?
I tried to use titanium backup to move some apps but it says my system is 2.38gb full

Rogers Note 3
Anyone can tell me if I can install it for the Canadian Rogers Galaxy Note 3 ?
Thank you

I have tried the rom but same result as yours. But don’t worry I have an alternative way to set the kernel for your primary rom.
First make folders in your SDCard, “MultiBoot” in it “Primary” it should be like: Sdcard/MultiBoot/Primary
Then extract the boot.img from your rom zip and copy it to Sdcard/MultiBoot/Primary
So the result will be Sdcard/MultiBoot/Primary/boot.img
It’s done.

To make space in your system partition.
1. Delete what ever apps you are not using from system/app and syatem/priv-app (Don’t delete if you don’t know what it is or what your are doing.)
Example: shealth, etc.
2. Move some google apps from /system/app to /data/app to make them user app using root explorer.
Example: maps, gmail, chrome, etc.

To dual boot two TW roms is very hard. Because there is not enough space to fit both system file in your system partition. Other wise you have to deboalt the primary rom and you have to deboalt secondary rom zip before flashing. And by doing so you will lose most of the features of your TW roms.
And if you want to use CM as primary and TW rom as secondary its possible but not recommended. Because you will have trouble with flashing mods etc for your TW rom.
The better option at the moment is to keep the TW rom as Primary and others a secondary.

[GUIDE] HOW To Multiboot on Lenovo P2

Hi guys I'll share with you how to multiboot roms on Lenovo P2 using an app called DualBoot Patcher.
Currently I'm using 3 roms, they're simultaneously installed on my phone and all I need to switch the rom is a single tap via the app we'll discuss below.
The roms I have installed right now:
-S062_170117_ROW as primary
-RR 5.8.2 as secondary
-S232_170320_ROW as data-slot
As you may already think about it, yes having 3 roms or more installed on your phone is eating your internal storage a bit.
Check the shots attached below for all the storage details for each Rom. I currently have 12GB free on the internal storage.
---
Okay let's start with the tutorial.
Requirements:
-Root
-Unlocked Bootloader
First of all I want to say Big Thanks to the developer of the DualBoot Patcher @chenxiaolong. Feel free to visit the official thread of the app, say/press thanks and if you're good even donate to him.
Also you can thank me for adding our great device Lenovo P2 to the supported devices. I opened pull request on GitHub that is already processed.
I'll start with the steps of my tutorial:
1)
The first thing of course is to download the app from it's official page
As of the time this guide is written make sure to download the build 9.2.0.r8.g4da14ed or newer as the older builds don't support Lenovo P2. Currently only the P2a42 model is supported, if there is interest from a P2c72 owners I'll add a pull request on GitHub.
2)
You have the apk, install it and set the kernel when the app asks you. Good thing is to update the ramdisk of the primary rom, but you still can multiboot even if you didn't. You can force update the ramdisk by hitting the update ramdisk button 3 times. Always reboot after setting kernel or updating the ramdisk.
3)
Now I assume you have the zip file for the other rom. Select "Patch zip file" from the side menu and choose where to install it. You have a choice of:
-Primary Rom Upgrade (not recommended, it will override your primary rom! For security reasons can only be selected from a rom different from primary.)
-Secondary (I recommend this if you wish to use only 2 Roms, the rom will be installed on the same partition as the primary rom, it won't affect the internal storage. Only the data will be on internal. The system partition of P2 is 3.87GB and you can put 2 roms there easily.)
-Multi-slot (not recommended, suitable for phones with large cache partitions, 1.5-2G)
-Data-slot (this will affect your internal storage, system and data on internal, reliable option if you use 3 or more roms.
-Extsd-slot ( the rom will be installed on your extsd card! Yeah you hear me, an awesome feature, but unfortunately kind of unstable, you have issues here and there and also you have slightly decreased performance as you're running the rom from your sdcard which is several times slower than the internal storage unless you're running one of the most expensive extsd cards.
Select secondary or data slot, choose a save path and patch the rom.
4)
Install the rom. Easy as it sounds. Press the pink button in bottom right, press it once again and select the rom you patched in the previous step. As you can see you can even restore a backup made with the app. It's not for restoring a twrp backup. You can backup roms within the DualBoot Patcher. Also you can flash roms patched with this app in twrp. Choose where to install it or leave it as it is and press the ✓ button in up right. The rom will be flashed.
Important! Don't switch to another app or do anything else when the rom is being installed, otherwise the patcher will crash! 1-2 minutes and you're done, not much of a waiting.
5)
Hey you made it. You now have 2 roms simultaneously installed on your phone! When you install a new rom the patcher will automatically switch to it. That doesn't mean it will auto reboot to the new rom, it will just switch to it in the Roms list, you can always switch to the primary or other rom again. I think that's pretty much about it guys. Now just switch to the new rom and select reboot from the side menu of the patcher, it will reboot to the new rom. You can repeat the procedure as many times as you want.
My record is 8 Roms, that was in the past with other phone. Because of this crazy number I'm a proud winner of the gold medal for the "Most number of multiboot roms installed lmao.
If you have questions feel free the write below and as always hit thanks if I was helpful. See ya. :highfive:
Update: Starting from build 9.2.0.r54.g8b79a2b the patcher now supports the P2c72 too!

so my P2c72 is on the way, you think it's not supported? Isn't everything the same except for the internal space? I was planning to flash the official P2a42 ROM anyways.
Thoughts?

I don't think, I'm sure it's not supported because I put the codenames on github and P2c72 is not in the list. No problem if you want to multiboot I'll add it in no time. You can flash all the roms available here for p2a42 on your P2c72 just fine by removing the first lines "assert get prop" in the updater-script. You can flash these roms the usual way via twrp. But if you use the DualBoot Patcher as for now it won't recognize the P2c72.

Cheers! My phone is on the way from china. Might be another week or so Right now just browsing everything that we have here.
Thanks for this. After so many ROMS ported recently, this would really help me out with having one stable daily driver and others to try to. Not an android developer but I'd like to try my hands as well finally to make a ROM and maybe look into the two bugs that are persistent across all ROMS. Let's see. I've just developed apps for now.
Anyways, thanks, this is indeed good stuff.

Yes, I love this app. It's the future of Rom's flashing, just switching between Roms like a boss. Btw congrats you bought the P2c72, it's 64gb right?

thanks, waiting for the bootloader to get done with its 15 days. All ready to flash everything!
Although can you tell me how it works? Like my phone is flashed with the global p2a42 ROM but it is p2c72. Should I change the name in build.prop?

Sorry brother didn't go through as I can't actually do it. Still waiting on my bootloader :/

So anyone had any success with p2c72?
I tried, but it fails. Doesn't throw any error but gets stuck in the boot and eventually reboots in twrp.
My only doubt is how does it know that the phone is p2c72? The build.prop says p2a42 so does the app thinks that its p2142 and wrongly patch it?

Is this just for experimenting or is there any advantage using 2 os same time? Isn't this can be cause a heat problem because of the more cpu/ram usage?

Can't find supported version of app! Can anyone here help me out wuth version?

How is battery life brother?

I can't say how's the battery life.
I just flashed this ROM and after flashing Magisk 12, Gapps and restoring some settings from Titanium Backup, I've got areally nasty overheating on my device and just went back to my previous ROM (AOSiP).
Btw, I've been using Dual Boot Patcher app to test all recent ROMS (RR, AoSiP, Validus...). Good app to switch between ROMs easily (screenshot attached).

Can you share the thread you followed for dual boot? Or write a thread on it? I've dual boot patcher apk, ends up booting into recovery every time I want to boot into secondary rom. If the ramdisk file of primary rom is modified, it also ends up booting into recovery.

I remember having some partition encryption issues when I first started using DBP and I had to format data/system partition to remove encryption.
As you can see from the screenshot I posted, I've been using all ROMs as "DATA" slots. Secondary ROMs don't work for me either.

I have data partition formatted, phone shows not encrypted now. I'll try installing in data slot.
No extra tweaks are required then?

Just patch the ROM zip to a new data slot and flash it from TWRP.
And remember to patch all zip files you want to flash on the ROM (GAPPS, SuperSU/Magisk) to the same slot you used for the ROM.

Hi. Im new to flashing and I want to use the dual boot. Where can I download it and how can I use it? A thread for our device would be nice. Thanks

I tried to download the latest build from qwertytom.cloudapp.net but the site can't be reached. Is there another download link?

[UNOFFICIAL][PATCHER][APP] DualBootPatcher for Galaxy S9+ Snapdragon/Exynos

I'm proud to present the first dual boot project for the Samsung Galaxy S9+ Snapdragon version. This project started off as a feature in my ROM, but not anymore. This will allow any number of ROMs to be installed at the same time. It works by patching the secondary ROM's installation scripts and boot image to load the ROM files from an alternate location (/system/multiboot, /cache/multiboot, and /data/multiboot). Because of the way this is implemented, no changes to the primary ROM are necessary.
NOTE
Treble-based ROMs are NOT supported(yet)! In-app ROM changing may not work on stock ROM (maybe it works, maybe not) so you have to use utilities.zip or flash the boot.img of every ROM! I do not own a S9+ so I rely on you guys!
Donators
A huge thanks goes out to all of the donators for supporting this project! I if forgot to add you (and you want to be added), please send me a quick PM.
See all of our supporters here
It patches...
Custom kernels for dual boot support
ROMs so that they can be installed as secondary
Google Apps packages for AOSP-based ROMs
SuperSU so that it can be used in the secondary ROM
NOTE: If you want to dualboot a TouchWiz ROM, I highly recommend installing TW as the primary ROM. Otherwise, any mods will need to be patched before flashing.
How to use the patcher
Android
Download the patcher apk and run it. Tap "Patch Zip File" from the navigation drawer and choose the file you want to patch.
After patching the zip file, a new file, like some_rom_dual.zip file will be created. For example, patching ktoonsez's
KT-SGS4-JB4.3-AOSP-TMO-08.28.2013.zip
would create a new
KT-SGS4-JB4.3-AOSP-TMO-08.28.2013_dual.zip
Instructions for dual booting
Before doing anything, download the Dual Boot Patcher app and the DualBootUtilities.zip from the download section below.
The patcher offers several locations for installing ROMs:
Primary: This is normally used for installing a zip to the primary ROM. It is not required, but is strongly recommended because it has code to prevent the zip from inadvertently affecting other ROMs.
Dual: Dual/Secondary is the first multiboot installation location. It installs to the system partition. This is a good spot for installing a second ROM because it doesn't take any space away from the internal storage.
Multi-slots: There are 3 multislots: multi-slot-1, multi-slot-2, multi-slot-3. These install to the cache partition. This is specifically for devices, like the Galaxy S4, that have a massive cache partition.
Data-slots: There can be an unlimited number of data slots. These install to the data partition and eat up space on the internal storage. This is useful for devices where the system partition is nearly full and the cache partition is tiny. These slots are named "data-slot-[id]", where "id" is something you provide in the app.
Extsd-slots: There can be an unlimited number of extsd slots. These install to the external SD card, which is useful as it keeps the ROMs off of the internal storage. Note that the ROM's data files are still stored on the data partition.
With that said, let's get to the "how to"!
First, boot into your primary ROM and install the Dual Boot Patcher app
Open the app and go to "Roms" in the navigation drawer. It will ask if you want to set the kernel. Make sure that you do.
Go to "Patch zip file" in the navigation drawer and patch the ROM or zip you want to install. You can select one of the installation locations described above.
Well, Just flash the patched zip file via recovery (Custom Recovery, like TWRP of course)
A normal backup from recovery will backup every ROM. If you would like to back up ROMs individually, please see @rlorange's awesome tool: http://forum.xda-developers.com/showthread.php?t=2491299
How do I...?
Switch the ROM if something doesn't work properly?
You can flash the DualBootUtilities zip from recovery. It will provide a menu interface that allows switching to the various ROMs.
If you have TWRP, you can also switch manually by tapping Install -> Images (bottom right) -> Go to /sdcard/MultiBoot/[Your ROM]/ -> flash boot.img.
Wipe /cache, /data, /system, or dalvik-cache?
The easiest way is to do it from the app while booted in another ROM. Just go to "Roms" in the navigation drawer, tap the 3 dots options menu for the ROM you want to wipe, and tap "Wipe ROM".
Alternatively, flash the DualBootUtilities zip from recovery, which will also allow you to wipe a ROM.
NOTE: Don't use the recovery's built-in wiping abilities as that may delete non-primary ROMs!
Update the primary ROM?
Patch the zip for primary and flash it. The "primary" installation target is designed so that other ROMs won't be affected when you want to flash something for the primary ROM.
Update a non-primary ROM?
Patch and flash the zip exactly like how you did it the first time.
Flash a mod or custom kernel for the primary ROM?
Patch it for primary before flashing. If the zip does not wipe /cache, it is also safe to flash it directly.
Flash a mod or custom kernel for a non-primary ROM?
Just patch and flash it

Yes root is needed, but the patcher does not support treble ROMs at this point. Maybe in the future.
Im not a programmer, I just add support for devices and compile it. The real programming is made by the official devs

please support for exynos

I will look into this.
But I cant guarantee for a fix because I have no skills in programming

Thank you very much,if anyone has any information about this plz let me know I'm really interested in this program

Does this work for anyone? and if so, using which roms.
Thanks

What do you mean with "for anyone"?
This self-compiled patcher works for S9+ Exynos and Snapdragon, but the official one works with around 150 devices.
One user asked me to make a version of DBP for S9+, so I did. (I dont own a S9+).
It should work with (nearly) every ROM, except for TouchWiz ROMs as second

Sorry, I mean for anyone with an s9+. I only ask because it was my understanding that dualbootpatcher doesn't support treble devices. Then I read this as well
https://github.com/chenxiaolong/DualBootPatcher/issues/1389 where chenxiaolong said treble devices weren't supported.
Edit: I added my device (xiaomi mi mix 2s) and compiled from chenxiaolong's sources, I can patch and flash ROMs, but the secondary roms get stuck in a boot loop

Original dbp as of now doesn't work on devices that have fstab inside dtb. If you've managed to find a workaround, can you share it please?

Yes, treble devices arent supported (yet?).
I dont know if the S9+ is treble based, but it seems like this version of DBP works for most S9+ users

Sorry, Im not a "real" dev.
All I did was following the instructions from the DBP wiki.

Is there anyone that can make a modded version of this that will work on non rooted phones and it doesn't have to be a dual boot patcher but just to get a different ROM running on top or VNC into and use. Maybe like a dual ROM runner.
