[Q] will installing custom ROM overwrite custom kernel? - Nexus 4 Q&A, Help & Troubleshooting

Sorry this is a total newb question
I currently have stock ROM with Franco kernel.
I would like to try out CM and have downloaded the zip file and copied it to my sdcard partition to install using CWM..
If I install the custom ROM, will the Franco kernel remain intact or will it be overwritten?
If it will be overwritten, what steps do I need to do to install the Franco kernel again? (Can I simply install CM and right after that the Franco kernel (both using CWM?))
Thanks

Yes it'll overwrite Franco kernel. To get it back after flashing cm, you simply flash Franco kernel again.

Thanks so much, if I do that (re flash the franco kernel) will my kernel settings remain ?

Don't think so.

It will overwrite your kernel and replace it with the roms built in kernel.

[Q] confused about kernal

I was wondering about the overclocking kernal for cm7. just how do i put it in. Do I have to do that when I first install or can I add it later. also does it really help. I mean is the difference really noticeable or not at all. I am still deciding if I should do it or not.
Kernels are flashed through ClockworkMod and can be flash anytime after you flash a rom. If you use the search bar you can easily find what particular kernel works for your setup.
OK, I think I found the right one but I was also wondering if I could install it when I first installed cm7. When I installed it I saw that it was searching for the kernel and for gapps but didn't find the n and skipped it. Could I install it then

CM7 has the ability to be overclocked as it sets.
settings > CM settings > performance > CPU settings.
just be extremely careful when Overclocking devices. it can takes it's toll in the long run.
and the g/apps are not kernel dependent they are ROM dependent.
OK but what do you mean by gapps are not kernal dependant

On *UNIX based devices. They have a section of the firmware called the "kernel". The kernel accepts the coding, binary and scripts from the RAM/ROM and tells the hardware how to act, what to do, and when to do it.
The g/apps have nothing to do with the kernel.
The g/apps are Google's property and cannot be included in AOSP based ROMs. Those ROMs are developed from Google's code. And developers do not have the ability to add those at will. So we must flash them after/prior (depending on he ROM) to get the Google Apps.
YES! DO IT!
for me its like day and night, it so much smoother with dals OC kernel. and yes you can flash the OC kernel any time. you can flash cm7 rc1 then OC kernel in the same boot. or you can first install cm7 to check it out for a while and then later flash the new kernel. if you planning to flash dal's 6/18 kernel, make sure to get his app NC Tweaks.

thanks. What I want to know is how to flash it. do I do it the same way as gapps( have wifi and reboot in recovery mode) or is there a different way?

You place the over clock zip file in the root of your sd card and flash it through cwm like you would a rom or gapps. So for example you would flash cm7 then gapps then the overclock kernel.
Not to Jack this thread, but I want to update from cm7 old kernel to New nightly build. Does the new kernel flash with the nightly?

When you move from stable cm7 to cm7 nightly the new kernel is included. However the included kernel is overclockable only to 975mhz. If you want a higher clock speed you'll have to use dals 6182011 kernel, up to 1200mhz.
whats is cmw?

it's actually CWM.
ClockWork Manager
basically boot into recovery then flash.
OK. but this may be a stupid question but will the cm7 kernal work with the stable version7.0.3 because that is what I have.

I'm not following you cannot use just a Cyanogen(mod) kernel. They are built into their ROMs.

sorry, but no. dal's 6/18 OC kernel will not work with 7.0.3....
...just flash n118 and you'll be fine
Ok thanks anyway. do you know when the kernal will work with a stable version

The latest nightly should be considered stable. It is in release candidate stable for the next stable build. The next stable build should be released in the next couple of days.

There is a Clockwork ROM Manager and a ClockworkMod Recovery image.
Together they are known as "CWM" Since one is a recovery and the other is a ROM manager.

[Q] Custom Recovery and Kernel's

I'm curious what everyone thinks the best Recovery is for the Razr M and what are the best kernels as far as functionality, battery life, and speed.
I haven't played around with installing custom kernels and ive been using the CWM recovery on my razr m and im currently running the AOKP custom ROM.
Dead Calm, arghhh kernel
Sent from my XT907 using Tapatalk 4
I think cwm is better than twrp but I am prejudiced by having wiped my extSD in one of the newest versions. See my signature link for an older BETTER version.
I like TWRP 2.6.0 and I had been having great performance with Carbon ROM 1.8 running the arrrghhh kernel. Currently though I'm having issues running arrrghhh kernel with the Carbon ROM 4.3 nightly (runs smooth with the provided kernel) and yes I did use the CM 10.2 version. I'm sure this will sort it's self after a few more updates.
***edit***
as of 8/16/2013 the arrrghhh kernel and carbon rom nightlies now work together properly

When installing a custom kernal, do i have to take any special steps such as wipe dalvic etc..? Or simply just flash zip from cwrm?
Making a backup and wiping cache and dalvik are always a good idea.

(4.3) Franco Kernel with PA 3.98

Hi,
I am running AOSPA 3.98 and need to install franco Kernel. In the downloads for the kernel I see separate Gapps to be flashed. So why do I need to flash the PA Gapps first and then the ones with Kernel?
I basically don't get the idea, sorry for my ignorance
Oh come on, no one?

Flash ROM (assuming you wipe first), flash gapps and then kernel.. That's it.. Oh and use jwr kernel from Franco for PA..

You can flash kernel before gapps. It doesn't matter. The ROM always goes first though.

No no, you don't have to flash a separate gapps if you have already flashed the PA Gapps. I think the gapps available for download from franco is for his own rom.
Thanks for the replies, I figured I was a total fool to consider them as mandatory to flash.
All I needed to do was flashing the zip

[Q] install AK kernel with slimkat rom

I am now using slimkat beta 1.95 with stock kernel of the rom and I want to flash the ak kernel v.305 on my phone.
Can I flash it directly?
BTW, how does this kernel do in battery life and what app can I use to adjust the performance?
Thanks...

And I am using the trickster Mod ,I fond a problem that I can't lock the min frequency to 162HZ or even 384hz, it will jump back to 912Hz automatically. Howver, the system monitor app shows that my cpu was working on 384-1512Hz.
Do you know how to solve this pro?
BTW, I have used ak kernel for almost 1 day and I think ak kernel makes the battery drain faster than the slim stock kernel....kind of upset:crying:

I'm using the US Cellular version which is the single SIM xt1607 and I've had no trouble unlocking boot loader and flashing twrp or any Rom, in stock Rom I was using xposed as well. Currently running axosp room with no issues.

Thank you bro. I previously used an MTK device and i know about flashing and rooting. But never used custom kernel. Can we use custom rom without any custom kernel? or is it necessary that i have to flash custom kernel for every custom rom?. Also give me links of bugless roms for our device?

I've been using the ASOPEtended Rom and have had no issues. Download can be found in the main Android development thread. As for custom kernels. I've been using squids kernel, but you can use the kernel built into the Rom with no issues

You flash the kernel just like the rom,I would flash the rom, then open gapps or bean gapps. Next I would flash supersu which you can find by doing a search of the forum, wipe dalvik cache, start finish setup then flash squid kernel. Also download kernel auditor from play store to get the most out of squid kernel. Helix kernel is another alternative based off squid kernel. Both squid and Helix allow you to change several options to improve battery life and performance.
