[Q] Boot loops after flashing kernels - Nexus 4 Q&A, Help & Troubleshooting

My Nexus 4 has been unable to flash most kernels without giving me a boot loop. I was on the Purity rom for a while and tried to flash Hellscore, Hellsdoctor, and Matr1x kernels but each would give me boot loops. However franco kernel flashed just fine. I then tried the Nexus 5 Experience rom with the CAF kernel packaged into the zip file and that flashed just fine. I now am trying C-Rom v5.6 and trying to flash the AK kernel v103 and it of course gives me a boot loop as well. I tried to flash Hellsdoctor to see if that would work, it did not. But franco kernel still flashed just fine for this rom as well. I did wipe data, cache, and dalvik and flashed the rom, then gapps, then the kernel. Unless I am missing something really stupid I do not understand why I cannot use most kernels. Any help would be greatly appreciated. Thanks!

i was on AOKP when i flashed franco and this happened... then i flashed FAUX123 and also happened.. but not the kernel with ROM....
until i figure out that most of those kernels only works on AOSP based kernels

Quick question abot franco.Kernel

Hi, I'm currently running stock rooted 4.22 rom and franco kernel r134 with ClockWork Recovery and I want to flash the ParanoidAndroid, what should I do? Should I just download PA and GAPPS, flash it with factory reset, dalvik and cache, and I will still have my franco kernel? Or should I flash kernel reset first and then flash PA?
When you flash the Rom you will lose the kernel and it will install the one included with the Rom if you want Franco kernel back you have to refresh it.
Flash ROM gapps Franco kernel and reboot done

d852 found a way to get custom aosp kernel running!

First flash this:
http://forum.xda-developers.com/lg-g3/development/kernel-optimized-sm-4-9-3-kernel-t2976049
I know what you're thinking, it says it's for d855 only...
What you do is immediately dirty flash your Rom afterwards, then gapps and voila, custom kernel goodness! Tested and working on validus and cm12
I'll add, before the dirty flash I had to attempt a boot which obviously didn't work. Then I bored into recovery, dirty flashed the Rom and gapps and I kept all the governors and tweaks.

Flashed wrong kernel. No touch anymore?

Hey guys,
I have a little problem with my new OP2.
I unlocked the bootloader and rooted etc.
I installed Paranoid Android and I wanst sure which kernel works on it.
So I tried flashing one for CM13 and one for OOS3, but both of them wouldnt work.
Now Im trying to get back to stock or atleast flash the boot.img from the Paranoid ROM.
I can boot, access the recovery and bootloader. I flashed different boot.imgs (Stock and Paranoid) and recoverys. But none of them helped.
The touchscreen wont react at all. If I boot, if I am in the recovery. It just wont work. Hardware button seems to be fine though.
Any ideas how to fix that?
Try wiping system partition and flash the PA ROM again (and Gapps of course) and it will restore system and kernel back to PA default.
If touch still doesn't work, then you'll probably have to wipe userdata partition as something you installed with the kernels not supporting other than official latest CM13 sources is messing with your system.
You need to flash full stock using fastboot from unbrick guide.

google megaunbrick guide oneplus2 and follow that!
didn't got your logic behind flashing custom kernel that too on paranoid android, I can understand that for cm13 as the battery life sucks there but pa easily gives 6+ hrs of sot which any other rom or even a custom kernel can't even come closer to it in my personal experience.
meaning you can try to flash the whole rom through fast boot or use unbrick guide to go full stock.

Custom Kernal Not booting

I have a Galaxy note 4 SM- N910V, i just recently updated my bootloader to the CPD1. I rooted, installed TWRP, and CyanogenMod 13 beta. It works flawlessly, but ive always had an issue with bluetooth sound that was fixed when i installed a custom kernel on BPA1. Now that i am updated to CPD1, i installed CyanogenMod13, and the emotion kernel, But now my Phone wont boot pass the CyanogenMod logo at the beginning. I did wipe cache and dalvik after in installed the Kernel. Any help is greatly apprecieted.
Thanks,
Deershoot3r
EDIT: Also i forgot to mention, i did a clean restore in odin, rooted, reflashed twrp. But this time i installed the Emotion Kernel first, THEN installed CyanogenMod/Gapps, and it booted perfectly BUT in settings my kernel doesnt say emotion it says "3.10.40-ga6f06c0 [email protected] #1"
When you flashed the kernel, then the ROM, the ROM overwrote (not sure what you think you installed the kernel to if the OS wasn't there?) the kernel, is my guess.
In any case, it simply sounds like you don't have a compatible kernel for the ROM. Ensure you have a kernel that's compatible with the ROM and your hardware.

Fastboot logo after flashing custom kernel

Everytime I try flashing custom kernel (Cherry Kernel or LOLZ) after rebooting I only see fastboot logo, the phone doesn't boot. I'm currently using Nusantara rom based on Android 12L, but this situation also has been happening on other roms. Can someone help me with this?
Edit: I am able to install LOLZ kernel, but only when clean flashing a rom, still not able to install it after already booting into the system. No luck installing Cherry Kernel either way tho.
