[Q] Custom rom in bootloop ? - Nexus 7 Q&A, Help & Troubleshooting

I have build from source CM12 and when I flashed the ROM it is in an infinite loop in the GOOGLE logo. I have done everything correctly.
I installed a CM12.1 build and there is no problem.
Flashed factory images of 5.0, 5.02 an 5.1.1 and then flashed my build but still it is in loop. No problem when I flash a CM12.1 build.
Can you point out what I did wrong ?

Sounds like kernel mismatch or misbuild to me. Really difficult to say more without looking over your shoulder during the build.

I build it twice, but still same problem.

Flash a prebuilt kernel over your custom build and see if it boots the ROM, then you know something is wrong with the kernel build and not the ROM if it boots.
Otherwise personally I don't know why you can't just use the built ROM flashable and not a self compiled version, unless you're trying to get into learning how to build roms?

[Q] Weird Colors after installing Franco Kernal

Hey guys,
I'm running the unofficial Cyanogenmod 11S on my Nexus 4 and just flashed Franco Kernel and am getting weird colours now. My screen also blinks at random times, anyway to fix this without factory resetting? Thanks
Flash your rom again without Franco kernel. It's the kernel that causes this behavior. Just re-flash your current rom/nightlie zip or whatever and it should be fine.

Wrong version of kernel used
I think most likely you have used the wrong kernel or not following installation instructions.
Whenever opt to install kernel, do look into the requirements:
a. for which version of android (4.4.4 ? 4.4.2? 5.0?)
b. what type of release of android (Cyanogenmod (CM/CAF)? AOSP? MIUI?)
c. installation method and steps (some kernels required to flash on top of stock kernel)
For now I would suggest that you find out the version and release of the android that you using currently and just flash the suitable kernel for it. The way i see it, you are using a cyanogenmod (CM), a CM compatible kernel will do.

[Q] Is it possible to get MultiRom working on Android 6.0?

First of all, thanks for looking at this question.
I am running Android 6.0 (Fake nexus ROM) for a week, and I like it! The problem: In the multirom app I cant select an custom Android 6.0 kernel. Anyone knows a solution? Can I use every kernel that support Android 6?
As far as I know it is not possible for now. We have to get something to Kernel related but I am not developer, so I do not know exactly what, hehe.
Flash AK kernel for aosp it has kexec support but multirom will only boot straight to twrp this can only be fixed my flashing stock image i tried

which told me to download kernels, modems and other things in order 9505 roms to work.
tried it- but with no sucess.
BTW i tried to use this rom: http://forum.xda-developers.com/galaxy-s4/i9505-develop/rom-albe95-lollirom-official-1-0-t3049564

Are you flashing a kernel right after flashing the ROM?

yes..
is that a prob?
edit: if i will flash stock, than kernel, and then rom- will it work?
Make sure the phone is running the latest bootloader and modem. Once that has been confirmed, perform a complete system wipe (system, cache, data) before flashing ROM, flash the ROM, and flash the kernel. Don't boot the phone out of recovery until after flashing the kernel.

thanks so muchhhhh u saved my asss
how do i check my bootloader & modem version?
I suggest flashing a stock ROM from here: http://www.sammobile.com/firmwares/database/GT-I9515/
Once that is done, you can flash TWRP from here: http://forum.xda-developers.com/galaxy-s4/general/galaxy-s4-value-edition-gt-i9515-t3190176
With TWRP, you can create a nandroid backup. If you flash a ROM that doesn't work properly, boot into TWRP and restore your nandroid backup and start over.
Sometimes, you may fine a ROM that will work without further modification. If not, a custom kernel may be required.
What are you talking about? The first link you posted linked to various rom threads for the I9515.
There is unofficial CM13 for the I9515, also known as jflteve.
There also was an unofficial SlimLP..
Unofficial CM13
Unofficial CM12.1
Unofficial SlimLP
As you can see, there are some roms. No need to mess around with patchers. Unless you really want touchwhiz..

Can't flash Custom Kernel

I tried flashing Fusion Kernel twice. First one was through fastboot, and gave me error. Something about strings & such. Second one is through TWRP. Flashed successfully but doesn't boot up at all.
Using Z00LD (Used kernel Z00L)
Custom Rom is CyanogeMod 13 latest one.
Help me plox
That's an outdated kernel. It won't work on latest cm13 builds. Check the last few pages of that kernel thread to know which build is supported.

I have already replied same thing on older thread, [ https://forum.xda-developers.com/moto-g4-plus/help/quick-questions-kernel-installations-t3794980 ]
if you flash ROM, it will also install kernel which is considered stock for that installed ROM. You need to flash kernel only if you have modified it (by flashing custom kernel or SU zips).
If you want to flash different ROM, you can flash without doing anything else, just wipe and flash.
PS invictaOS is discontinued long ago, invictaOS-Nougat is stable, Oreo will be more bugfull than current available ROMs..

Though these forums are for the Moto G4 Plus, that does suggest an issue with the build of Lineage OS that you're using. Can you confirm with the developer that this build is successfully running on their device? Do you have a compatible Lineage 17 OS based kernel you could try to flash?
Was your device working with other stock or custom ROMs before flashing Lineage 17?
