Can I flash a jss build over the jwr stock ROM? - Nexus 4 Q&A, Help & Troubleshooting

Hello! Can I flash an AOSP based ROM like Cyanogenmod just flash over the JWR stock ROM and it will be fine? The screen issues are only kernel related so I guess the CM kernel is based on AOSP and I can just flash it?
And when for example there comes a 4.3.1 stock ROM leak, I can just flash it over the CM ROM in recovery?

[Q] How to flash Quarks Custom Kernels

Dear All,
Greetings !!!!!
I have green lense defy in which i had accidently flashed defy plus rom. now my defy is on sbf of defy plus as it is non down (BL7)
For almost 1 month My camera was dead but after flashing quarks 2nd boot rom ( which includes custom kernels) my camera starts working.
Now if i flash other roms for eq. rapidroid / miui / wajkUI then kernels changes ( it shows kernel name like hudson ) & again my camera wont work.
Should I flash custom kernel of quarks on the above mentioned roms?? Will Camera work ???
Please guide me ...Thanks in Advnce...
Latest Qarx ROM's have kernel embedded so you do not need to flash nothing more but gapps. Do cash and dalvic wipe and flash newest 18/10 ROM then gapps.
The ROM is unified and suits any kind of Defy

Oops! Quarx kernel is for JB, which contains jb ramdisk internally. It won't boot for other than jb builds. You can install any jb rom, like, aokp, cna, slimbean all work with Quarx kernel, but not with any other cm9 and less builds.
Please Specify in details...

No. These ROMs have the kernel embedded in them. You just need to Flash the zip file through recovery.

Premaca,
Does this mean that there is no way to downgrade to other roms like MIUI (gingerbread based) or the stock defy Froyo rom using a nandroid backup?
At present there is no way to do so...

You can go back from the custom kernel to your stock rom. The custom kernel doesn't change your bootloader version. So no need to worry.

Dear Uman, Ur reply will definately help thousands of defy user (mb525 ) who have accidently flashed full sbf of defy plus (mb 526) and who are on BL 7. Before quarks custom kernels i.e. second boot roms camera of all those defy users was dead. Only after flashing quarks second boot rom camera becomes on!!! But I have gone through full XDA Forum & according to my RnD, at present there is no way to downgrade BL7. For ur information I had tried 2.2 nandroid backup but it was giving me bootloader error, further more I had switched to other GB Roms but then kernels changes and phone was working fine without camera.. Kindly confirm ur reply so that I will once again try to do so......:good:

[Q] %95 of kernels break my camera.

It seems on pretty much any rom with a custom kernel breaks my camera. When I focus it goes all screwy and crashes. Changing the GPU govenor dosent help. Any ideas how to stop this? Even on JWR with a JWR kernel it happens. Im stuck using stock 4.2.2 with stock kernel because it kills my camera.

wait wait! are you using JWR or JSS on a 4.2.2 rom?
update to 4.3 and when you get it now flash a kernel JWR if you are in stock rom if not and you are using Carbon rom, Rasbeanjelly,Cyanogenmod use JSS (JLS now) if you are on Paranoid , PSX , Purity flash JWR kernel then.
this should be fix your problem on camera!

Lol. I know. I was just saying even if I use a kernel written for specifically JWR on JWR it still bug's. Basically any kernel with any rom other than stock breaks my camera. Im aware about the different kernel and rom types.

Franco Kernel On CyanogenMod 12.1?

Hi,
I want to see if i can get Franco Kernel on my Nexus 4 running CyanogenMod 12.1. I tried using auto flash on the Franco Kernel app on the app store and it gave me a warning stating it might not work... Any suggestions whether it works or not? I don't want to ruin my phone
I tried this yesterday and my Nexus 4 was stuck in a bootloop after until I reflashed CM 12.1.
In short; no, don't do it.
There is two different types of Rom's and kernels. There is those that are based on AOSP and those who are based on CAF.
You can't mix different types of Rom's and kernels. So to you can't use a AOSP kernel on a CAF Rom and vice verca.
CM is a CAF based Rom and Franco kernel is an AOSP based kernel. So you can't use those together.

Can someone port Asus' stock kernel for CM12.1/RR based ROMs ?

As the title says. I switched to a custom stock ROM and started using the stock kernel with it, the stock kernel is so smooth, I fell in love with it. The performance wasn't the same in RR ROM. It provides the same battery backup as other kernels I have used..including quanganh's, X AnwarMov's and BORETS24's custom stock kernel. Can someone port the stock kernel for CM based ROMs ? Or is tank0412's custom kernel is what I'm asking for ?
Try this:
It a stock kernel which was ported to CM12.1/RR:
