No cm12 rom boots in multirom - ONE Q&A, Help & Troubleshooting

My setup -
Multirom modded twrp
Multirom
Stock Rom with multirom kernel ( AK )
I can boot 4.4 based roms as secondary rom with multirom for e.g the official Paranoid Android.
BUT
i have tried almost 5-10 CM12 roms and none of them boot as secendory roms.
ALTHOUGH,
the stock cm12 unofficial build had booted once ( the 1st time i used multirom ).
But after that neither has that rom booted, nor any other cm12 rom!!
Please help me!

That's because lollipop ROMs can only be used as a primary, it's been pretty widely discussed.

They can be installed as secondary with a modified updater-script file that the Dev needs to provide as it's ROM specific from my understanding. Try the temasek unofficial cm12 ROM and use zarchiver to delete the original updater-script file and replace it with the modified one provided by @katinatez
This will allow you to install the ROM. If it doesn't boot after that that's a different problem

Unable to install Cyanogenmod 11

I am perplexed:
I had previously installed many custom roms after updating to stock kitkat, including CM 11. However, I am not able instally cyanogenmod, AT ALL. I have gone through all the steps and all the recoveries, CWM & TWRP all versions. After the installation, the phone hangs on the boot logo, always.
Any clue would be appreciated. Thank you.
U sure u flashed/fastbooted the recommended kernel correctly and did a full wipe before installing the Rom?

I highly doubt you installed CM11 with the KitKat kernel installed. It won't work. The only way it would work is to FXZ back to JB and then install the previous version of CWM or TWRP.
Currently, there are no ROMs working with the KitKat versions of CM11 or TWRP, although dhacker is working on a new CM11 using the latest KK kernel for the RAZR HD phones and the developer for the Nexesque ROM is also working on an updated version that uses the KitKat kernel as well.

It was very strange situation. I ended up getting CM to work by using CWM 6.0.4.4. FMI (for my information), I need to use CWM 6.0.4.4 will be needed to install custom roms.
Thanks for the advice..

[Q] Problem that happened using Multirom, now i have an unusable phone

I had the latest version of CM11 on my Opo 64 GB, was also using Multirom and Miui 4.10.24.
Tried to install the 4.10.31 version, but i did it wrong (i did not go into TWRP, then Multirom, add zip and install, but i just selected install rom and flashed the 4.10.31 zip file).
Now, the main CM11 OS is lost, i cannot boot into it, and i cannot also boot into MIUI.
So, how can i get my CM11 back?
I tried flashing the official version but it gives me error while trying to install it through TWRP.
Also if i reboot the phone and try to choose the MIUI it says
"error, kexec-hardboot support is required to boot this rom.
install kernel with kexec-hardboot support to your internal rom.
Any help would be greatly appreciated!

Yes I can, managed to install MIUI only, latest version.
I also installed Multirom again (on MIUI) and it downloaded cm11s kernel).
Ok managed to go back to my old miui os, now I have 2 miui os and no cm11, also downloaded the Franco kernel 30. How can i check if the cm11 that i had before is still there, if not how can i install it again without screwing my already working miui?
update:
After some tests, this is what's happening.
I believe I have no CM11S on my phone, that is gone!
I have the MIUI V5 running, but when i flash the franco kernel, the phone is stuck on boot (1+1 logo), i have to flash the kernel_kexec_bacon_cm11s to make it boot in MIUI (working).
So, now i have a working rom that works through Mutlirom and I cannot flash a working CM11S rom on the phone.
Any help would be great guys!

Dirty unicorns rom kernel

Im about to flash dirty unicorns 5.0.2 . I already have twrp recovery and have downloaded the elementalx 2.08 kernel.. Do i have to install kernel in order to install the rom or everything will be fine with the stock lollipop kernel?
Usually the ROM is packed with the kernel that is compatible. So every ROM has it's 'default' kernel You can replace it with ElementalX afterwards though

BUT it's ALWAYS better to read a few pages from the ROM's thread before flashing it.
Actually if you flash BlissPop rom today then your device won't boot (issue with stock kernel). So you must flash a custom kernel to be able to boot to Android.

[Q] Android kexec kernel won't install in secondary ROM

I moved my primary Android ROM to a secondary ROM in MultiROM but now it won't boot, even after re-flashing the kexec patched kernel. The kernel flash itself reports success but I get the kexec error when trying to boot that Android ROM from MultiROM. The primary CM12.1 ROM boots fine.
I realize now that the primary ROM must have the kexec patched kernel. That cleared this up.

How to install CM13 on XT1033 running CM12 with custom kernel Hurtsky Stable 13?

I want to install MM roms on my phone,stock or CM based. But the problem is that I installed Hurtsky Stable Kernel for 5.1. Do I need to flash a stock kernel of 5.1 to be able to flash 6.0 roms or do I need to flash any kernel for 6.0 roms. And if I do flash a stock kernel for MM rom while running CM12, will my phone boot?
You have only to make a full wipe via twrp recovery (Wipe system, data, cache, art-cache) and install zip of CM13 and gapps.
Download the main system zip from: https://download.cyanogenmod.org/?device=falcon
And the gapps from: http://opengapps.org/ (choose the 6.0 one).
There aren't stock based, because Moto G 1st gen (2013) does NOT HAVE 6.0 official!
There is also an Identiti crisis rom, a porting from moto g 2014, but CM13 is more stable!
All right.Thank you for replying! My concern is about the kernel. The kernel I flashed is meant for LP CM Roms and not MM. So when I flash CM13 with gapps,won't it create a problem? Will I have to flash stock 6.0 kernel or a kernel for MM CM Roms?
No, the kernel is replaced when you install a ROM. The kernel is a part of system, the heart of ROM, contains all the driver (called modules) and also set the CPU and GPU frequences. So you don't have problem if you install the zip because in the zip there is the default 6.0 kernel (if you see in the zip there is a file called boot.img).
Ohh! Thanks a lot! I shall try CM13 now!
