What kernel?

Hey everyone... Just got home from buying my nexus 4... rooted a few minutes ago and got pa installed. Some of the kernels I used on my galaxy nexus aren't here which I'm sure will be OK.... Are there any kernels that stand out above the others in any way?
Thanks for the help!

I'm using Franco Milestone M1 kernel. Seems to be a great combo with PA with about 4.5-5 hrs of SOT. But try other kernel for yourself and see which one is best for you.

I have tried every kernel here, and the best one that works for me is the enhanced stock kernel. Can under clock, under volt and is the snappiest one . Battery life is good too, plus touch control also works

Link?
Will this be compatible with 0.33 radio and tmobile lte?

It is the enhanced 4.2.2 stock kernel by Faux, you can download it from the first page of his thread.
Yes, it should work fine with .33 radio and LTE.

that has nothing to do with flashing kernels. dont listen to anyone that says they recommend to, theyre clueless. btw, try trinity kernel. and while youre at it, every kernel here is good. find the one that fills your needs and that your device likes best.

OP as pointed out....
Thanks

A question about ROMs and Kernels

Ok, so I've rooted and flashed rasbeanjelly from the nexus4root(dot)com website.
I've set everything up, down loaded apps I want etc, however I've heard that trinity kernel is very good with this ROM, if I'm wrong and there's a better kernel correct me. So how do I install the kernel? Same way I did the ROM? Is it compatible? Do I have to wipe everything? Is there a better kernel to use?
Thanks a lot for reading.

Just flash the .zip in recovery, no need to wipe anything. There's no 'best' kernel so your question about better kernels could easily get 20 different replies.

Ok thanks for your reply, what about compatibility? I've heard that if ROMs and kernels aren't compatible it can brick your phone

As long as the kernel and ROM you download are for the N4 it should be perfectly fine. In the future with new releases of Android there may be some issues, but devs usually make it pretty clear in the OP what you risk by flashing your phone.

rasbean and trinity are very compatible
as are all the other nexus 4 kernels.

[Q] Timur and Kexec-Hardboot kernels together!? (using MultiROM AND USBRom together?)

Hey everyone.
i was wondering if i could have Timur's great kernel for USB Host power management AND be able to boot in ubuntu or other android roms, using amazing MultiRom?
i found that i have to use a patch or sth. like that, but i have no idea what i should do.
can anyone give me a step by step guide? noob proof?!!

Timur's kernel already includes the kexec-hardboot patch. When installing Ubuntu with MultiRom you are to select "Don't share kernel with Internal ROM".

Yes, Timur added the patch several months ago. And when you install ubuntu, you dont need to pick dont share kernel. The way multirom is set up, you cant share the kernel, because when you choose ubuntu as the medium, the option is automatically removed.

I should have been more clear. The 2013-01-24 kernel does not have tje kexec patch. He implemented it after that date. Use the cm kernel from april or may.

Is it ok to use cm kernel on stock rom? :S
Sent from my Nexus 7 using XDA Premium HD app

Cm means cyanogenMod, right? So installing the cm kernel on stock rom may harm my device, and the stock kernel doesnt support kexec, right?
Sent from my Nexus 7 using XDA Premium HD app

So, my problem gets worse. Can anyone give me a link to stock kernel?
Sent from my Nexus 7 using XDA Premium HD app

I'm Right?

So i just rooted my Nexus 7 and also, i installed CWM. I want to flash CyanogenMod ROM (cm-10.1.3-RC2-grouper) and i'm wondering what gapps i need? I'm really confused about the file i need.
Also, tell me if i'm right I copy the files on my Nexus7 (ROM and GAPPS). I boot into recovery and flash first the rom than the gapps. Before, i do the wipe to be sure it won't bootloop.
Right?

Any4.2 gapps will do, also afaik them emulated sdcard wont be wiped. Any reason you're not trying 4.3?

The ROM doesn't control the over clock. You need to look into kernels.

[Q] CM 10.2 nightly won't boot after flashing franco r191-JSS

Hello,
I am running CM 10.2 (latest nightly). I flashed the franco kernel r191 for the first time and it bricked the phone. The boot animation won't come up. It gets stuck after the Google logo. I would appreciate if you could help me out. Fortunately, I had a full nandroid backup and was able to recover my phone.
I use the TWRP recovery.
Thanks.

You need to learn what the definition of bricked means.

a bricked phone is worthless and unrecoverable, it makes a great paperweight/door stop. flashing a kernel that wont boot is not bricking a phone, and not close, and there are many ways to recover from a non booting kernel, nandroid restore being one way. you can also just flash a good kernel or your rom to recover.

Thank you for clarifying the definition of brick. I did not know that. Please feel free to chime in regarding my original question. Thank you.

What IS your question? From what I've read, you were able to restore your nandroid, right? Just don't flash that kernel if it messes things up.

try a different franco kernel. are you sure that you pucjed the right kernel? 4.2.2 kernels dont boot on 4.3, and 4.3 kernels dont boot on 4.2.2.

According to the author, I am supposed to flash the one that has a JSS tag in the file name. http://franciscofranco.minooch.com/Nexus4/4.3/zips/
I am sure I downloaded the correct file and flashed the right version. Since I am new here, I am not allowed to post in the original thread, which is here:

I would like to know whether there is a way to flash the franco kernel on CM 10.2. It seems to be buggy. I wanted to post my question here: http://forum.xda-developers.com/showthread.php?t=2002782
But I need at least 10 posts to ask my question there.

no. custom kernels no longer work on cm properly, if at all.thats probably is the reason why franco kernel wont boot. cm changed their base code from aosp to qualcomm a few weeks ago, and that broke the ability to use custom kernels on cm. custom kernels are based on aosp, and qualcomms code breaks stuff because of it.

Thank you so much! Now I understand why.

Started a couple of days ago. Not sure if the r191 is the cause or the cm 10.2 nightly.
Sent from my Nexus 4 using xda app-developers app

As said previously CM is the cause, Franco still remains AOSP based, you can try hellscore kernel, Google it, it as a nice reputation for amazing battery life and has a CM version of it.

I don't even like the way that term is used to be honest. To me a soft brick is more or less something that requires a JTAG.
A bootloop or a failed boot just isn't any type of brick at all really as far as I'm concerned.

You really should change the title of the thread. Franco does great work and really does not need to be slandered. After all cm is preventing your device from booting not Franco's kernel. If you want to rant maybe you could change the title to cm bricked my phone
