[Q] Cant install a custom kernel - Nexus 4 Q&A, Help & Troubleshooting

Hey people, i recently bought a new nexus 4 and im LOVING it.
I seem to have a problem with custom kernels, i cant seem to boot up once i install one. Ive tried 3 different kernels ( Purity, Matr1x and Franco ) with the same results. here's what i do and what happens:
1) install a new rom after wiping everything in CWM recovery
2) Install Gapps
3) Install the kernel
4) Reboot
Everything installs successfully but when i boot up, after the 'Google' image when the boot animation is supposed to play out, i get a black screen with nothing on it. And the phone doesnt boot.
If i dont install the rom without the kernel, it boots up. ive also tried installing the rom, gapps and booting it and setting it up ( google account, etc ) and then go to recovery and installing the kernel, still the same results. And ive also tried using different roms and i still get the black screen
Hope ive explained everything
I have an idea that maybe i can change the default kernel that comes with the rom by copying the stuff from a kernel zip and pasting it somewhere in the rom zip. Can it be done? If yes, what exactly do i copy?
THANKS!

very importantly, what rom are you using? not all roms are the same. and no, you cant update a kernel that way.

ok reflash your rom and other stuff(without a custom kernel), boot up/set up, then go back and flash this trinity kernel, tf152 http://goo.gl/CDAGV7
did it boot?

Yes you can, but it depends on how the kernel is structured inside the flashable zip. If it's just a boot.img file inside, you can definitely just drag & drop it into the flashable rom zip and replace the original one. Some kernels will work, others will not. If you're going from a rom that uses franco to one that uses an original ramdisk, for example, you may run into issues, but in most cases this won't be an issue.

It did boot up with the trinity kernel although the app drawer didnt seem as smooth and fast and there was a problem with the widgets
And its the Liquid kernel, do u want me to type whatever is under the "kernel version"?

yes please.
earlier for the franco kernel, other kernels flashed over it wouldnt boot, only flashing the other kernels with the rom would let them boot. franco kernel has modified ramdisk, framcisco had to adjust it so other kernels would boot up after. i have a feeling that something similar is whats going on with their kernel. especially since you say trinity booted but the app drawer is laggy. i bet they also have modified ramdisk(or something messed up by accident).

its probably a modified stock kernel. did you ask in their thread if this is the normal behavior with custom kernels?

No actually, i didnt. I see your point but what happens with the other roms. XenonHD or Xylon, they have the same problem.
maybe its important but i coudnt get into the stock recovery before i rooted my phone. When i got into fastboot and selected recovery, i would get an android with a red triangle saying ' no command' and i had to press Volume up and power buttons to see the menu

lots of roms here are related to one another, some very related, so more distant. liquidsmooth doesnt do much of their own coding, they pick up stuff from other roms/sources. these roms might be very similar.
but honestly, i dont know. it is a weird issue though.

[Q] flashing CM9

when installing CM9 to your defy is it the same process for flashing CM7 or is there a slight variation or something?

The original thread was Dev based, about the ROM being released and how stable it is as released. This thread was noob based about how to flash said ROM and if it is different from another, very similar ROM.
Why clutter one thread when you can have two?
Anyway, to answer the question instead of of questioning the question, Yes the basic principle is the same. Once you have the System Recovery installed, it's a case of copying the CM9 zip file to your SD card and flashing the same as CM7, although the way I've personally done it is using Multiboot, so that I can normally use CM7 for "production" but can have a go and see how CM9 is progressing for a few minutes or so.

Reboot and press vol- when you seen blue light. You'll be taken to the bootmenu. It's stated in there version of your current bootmenu.
And yes you need to change it speaking of compatibility..

Running stock rom, rooted, which kernel suggested?

Kind of burned out of flashing all these different roms. Dont get me wrong, I appreciate all the hard work everyone is providing for us. But I am burned out and wasting hours of my day flashing rom after rom etc.
So I went back to stock and rooted. But I did want to see if there was any advice on any kernel out there that I should be running with the latest stock build?
Thank you,

Der Kernel - Trinity. Comes in high OC version a96 to lower of but slightly irregularities a110 and many more. YMMV but this is a solid, customizable kernel.
Is there a secret to flashing the trinity kernel?
I reboot into TWRP, wipe cache and /dalvik 2x (old habit) flash Trinity, reboot but still shows previous kernel under settings?

whats your previous kernel and whats in say in kernel version? btw, you dont need to wipe anything when flashing a kernel. anyways, only if you are coming from franco kernel you have to reflash your rom with trinity kernel(flash rom, trinity, reboot). this is because franco kernel uses its own ramdisk(frano kernel tweaks are in there). trinity and just about every other kernel use anykernel which grabs the roms ramdisk usually(unless you had frano kernel). so you want to flash your rom, then trinity, then bootup to resolve the issue. after that you can just flash the kernel. remember, no need to wipe a thing when flashing kernels.

Nexus 4 Franco-Kernel Recovery

Hallo,
i just tried to flash Franco Kernel v191 to enable USB-OTG on my Nexus 4.
But now i can only boot into CWM Recovery.
When i boot normally, the Screen of my Phone stays black after i see the Google-Logo.
I'm not sure if i flashed the right Version (Do i need JWR or JSS?).
I also flashed only the *.img-File, not the .zip, which was obviously wrong.
How can i flash the right Kernel (or maybe the stock one first) ?
Im using the Nexus Toolkit.
Help me please.

stop using the nexus toolkits. flash via recovery if a zip, or via fastboot if an img file.
I did flash the Kernel directly via Clockwork Recovery.
Which Version do i have to flash?
I manged to reinstall Cyanogenmod now.
But the ADB-Bridge to the PC doesnt seem to work anymore :/
I enabled USB-Debugging and PTP, but the pc doesnt recognize my phone.
Any Ideas how i can fix that?

oh, youre running cm, thats why. cm changed its source from aosp to qualcomm, so custom kernels are now a no go since the custom kernels are aosp based. the kernels that do boot up on cm, mess up the colors, and franco kernel has issues booting cm. its actually not franco kernels fault, its cm that messed it up for our community(unless you are using cm based kernels).

Bootloop on DirtyUnicorn
Hi , nice work. I've been using HellsDoctor and the battery life is just amazing... but, when I try to flash TARDIS I got bootloop.
Running DirtyUnicorns[Du_mako_4.4.4_20140823.v.7.9-OFFICIAL] and 3.4.104-hells-Doctor-R6.
I am sure I've followed the steps and also I tried some combinations by myself but still isn't working.
Thx in advance.

CM version
Hello, and thanks for this awesome kernel!
I was trying to flash Dirty Unicorns and Hell's Doctor today, but all kinds of strange behavior ensued. (namely: I lost my display, while ADB could see the device normally).
I flashed the CM version, so am I correct to believe that I should flash the AOSP one?

I will answer my own question here, based on the search in DU's thread:
We need:
- AOSP kernel version
- Revert_4.4.3_Wifi_Fix.zip from http://bit.ly/makostuff (thanks @gorilla p )
and If you want to flash TARDIS, chose CAF dalvik libs.
Tested with HD3_R6 on DU 8.1 & 8.2 and all is well.

How do I flash this on a clean Lollipop install? It's not clear.

I'm having problems with the battery like someone reported before.
The Wi-Fi seems to appear active even if I shutdown.
Some search boxes when are suggesting options the image appears strange.
As I am a new user I can't post images.
Can you include volume rocker wake phone, please?
@AnaguaMateus The volume rocker is included in the N5X-ROM
I'm using this ROM and it has very cool features, I recommand it A new build is going to be release in few hours
Also a FULL WIPE is recommended if you have those bugs

It means that your N4 didn't shut down properly last time so Synapse isn't applying the parameters you've set in the last session/boot

I think the easiest way for you is to install HellsCore Kernel Manager intead of Synapse, the most important parameters are configurables and you don't need to deal with those permissive boot images, UKM, and flash things ;P

Boot into recovery (hold power for 10 seconds to reboot, then volume down to go into fastboot mode) and then flash your ROM again.
Reboot to see if it boots ok, then flash HD, without TARDIS. If this boots successfully, flash TARDIS, with extra care to choose the correct dalvik (if applicable)

What I'm trying to do is to uninstall the kernel (if that's even possible) and reinstall it or reinstall it and now I want to know if it's even possible
Second question is if it's even healthy to install a kernel on another kernel? could that the reason why "Kernel (Android OS)" is taking up so much battery power?
(I've been playing around with ElementalX and Loony and Frostbitten)
Custom kernels instructions definitely say to be installed ONLY over the stock kernel.

Do you know by any chances where to get the stock kernel?
I usually reinstall the stock without wiping the data.

Kernel is basic requirement for OS to run, it controls (processor and) more than that you can see in any kernel manager.
Without kernel, your device will never boot.
Also can you explain, why you want to uninstall and reinstall ?

Stock kernel with many ROM comes with less tweaks allowed, but custom kernel gives you more features/tweaks and wakelocks, so it may increase performance of device and battery too..

In custom kernel thread,
Stock kernel means, the kernel which comes preloaded with any ROM that you installed.
Boot.img in ROM zip is stock kernel for that ROM.
You don't need to flash another kernel.
