[Q] About custom Kernels and overclock, some questions

Hi,
After some weeks with my GN i think i'm ready to try a new kernel.
Currently i'm using the AOKP M4. My question is : to flash the new kernel, i just put in the SDcard and install it in recovery mode ? Do i need to wipe anything ? Will i loose any data ?
If anything goes wrong, i all need is to restore the last backup, right ?
What kernel do you guys recommend with AOKP ? I'd like to have options to overclock ; they said the 'normal' clock o GN would be 1.5ghz, so i can run in this clock without risks, is this true ?
Thanks in advance !

You are correct - drop the kernel's .zip onto your SD card and flash it in recovery. There is no need to wipe (in fact, DO NOT WIPE). You won't lose anything. If you have issues with the kernel, you can always revert back to the "stock" kernel by reflashing the AOKP .zip
I've had great results with faux's kernel: http://rootzwiki.com/topic/11552-gn-gsmhybrid-3024-ics40234pre-uvoctuncifsotgfiopsv014mar-22
All hardware is created differently so you may or may not be able to OC to 1.5GHz. For stability and battery life I usually OC to 1350MHz... but I also usually run an underclock at 1060MHz for even better battery life. 1060MHz is plenty powerful for everyday use, calls, web browsing, etc, and I've got a Tasker widget set up to instantly toggle between the two clocks for gaming and such.

That is not true, you need to wipe cache and dalvik-cache when flashing a kernel or you could run into bootloops or crashing issues.
If you are on a 4.0.3 or 4.0.4 ROM then use a kernel from either of those versions. Dont use a kernel designed for 4.0.2 or earlier with any later ROM versions
Glados kernel has the best overclocking by far
Popcorn kernel seems to be the fastest with stability
Minimalistic kernel (forget the actual name) is the best on stability but is a bit slower than others
Franco has random experimental features that sometimes work really well, and sometimes you have lots of problems, his has least stability of anyone.
Tuna kernel seems just all around average in all areas, not excelling at any one thing but not bad in any areas.

Eh, it really depends on the kernel you're flashing. I very rarely do any wipes when flashing a kernel... the only kernel that's ever given me problems with that is GLaDOS - probably due to how different its ramdisk is from stock.

lol are you serious? his kernel is one of the most stable kernels ive ever used. r121 and r161 are both nightly builds and have been EXTREMELY stable with amazing battery life. his kernel just gets better and better.
i have yet to get a sod or reboot on this kernel

Glados kernel has no RAMdisk, its creator believes the RAMdisk should belong to the ROM and not the kernel. So you have issues when flashing to Glados from another kenerl because you still are running the old kernel's RAMdisk with the different, new kernel. If everyone follows this proper procedure we would have no issues and higher compatibility with ROMs and kernels. Unfortunately most custom kernels like to use their own RAMdisk and so issues arise.

Franco is quick to fix problems so you probably dont notice, however if you read through his thread there are often releases with bugs in it. Things from Wakelock issues, sleep of death, and broken wifi. He fixes these of course usually within a few hours but you never want to grab the latest kernel when it is first released. Always wait to see who has problems and for a fix to be released. Usually the last release of the night has no real bugs. Franco's quick releases are both the cause and solution to the bugs in his kernel. Other people test more so release with less bugs. Also Franco likes to put experimental stuff like 512MHz and 480MHz GPU clocks in, which dont even run on some peoples phones.

Try popcorn kernel. I'm running it since day one without a problem, it's snappier than stock and battery lasts much longer.

So that would be quite different from stock then
I couldn't remember what exactly it was that made GLaDOS so different; I've been off that kernel for a while. It seemed to have a lot of really cool ideas put into it, but it didn't work well overall for me (yes, even after flashing faux's reset kernel and wiping cache and dalvik). I had a lot of SOD issues (with "stock" clock and voltage settings), and I could never get the logcat module to work properly. I break enough applications that I can't really get by without logcat.

That is why there are TWO builds. Milestone and nightly builds.
Milestone are for people who want stability, nightly builds are for people who want the newest and latest things.
Wakelock issues come from apps, the wakelock issue was already fixed. This is the purpose of nightlies, they are there to report bugs. If you don't like that then stick to Milestone builds. That is why these two releases are separated.
Sleep of Death is mainly caused by users who undervolt their phones. This is no way franco or the kernel dev's fault.
Broken wifi? Never had that bug. People experience this bug on other kernels as well. This isn't caused by franco's kernel.
512 MHz.. that is why there are TWO releases for nightlies. One is in 384 and one is in 512 MHz. Milestone builds are ALWAYS on stock clock because stability is #1 priority in those builds.
http://minooch.com/franciscofranco/Galaxy Nexus/nightlies/ (384 mhz folder at the bottom).
There is a reason why franco's kernel is the most popular kernel in Galaxy Nexus and he is a very well respected and known developer.

Thanks everybody for the returns.
But now i'm confused : should i wipe or not wipe ? If i wipe, will i loose my apps and data ?
If anything goes wrong, when i restore a nandroid backup, will the kernel be restored as well ?
Thanks !

You don't need to wipe your data partition. You may wipe your cache or dalvik-cache, but you won't lose any data doing that.
If anything goes wrong, you can just reflash your existing ROM's update.zip - it will restore the stock kernel without losing any information, and will be a lot quicker than a nandroid restore.

Good Kernel and Rom

Hello dear Community,
i am owning a GN and i Rooted it about 2 weeks ago.
So now my problem is i tryed some Roms and Kernels.
But i wasnt happy with theese.
To much bugs or to fast Battery drain. And instable.
So my question is which Kernel and Roms are good?
I prefer:
Good - High Battery perfomance
Stable.
Can have a good design.
And a lot Functionality.
My GN is GSM. With Maguro.
Im Actually using PARANOIDANDROID.
Sry for my english, thats scool english
Ant thanks a lot for all replies

PARANOIDANDROID is a good ROM but a little Alpha imho. I recommend the following in order of quality and support. I'll recommend Franco nightly kernel with either LiquidSmooth 1.35 or FoxHound 0.6. I'd recommend BAMF but if you go to their thread for support, they got some real douches in there.

Well thank u for ur reply.
I am not a pro but a newbie at flashing roms and kernels.
But i wanna try ur Variation.
Can u explain me how to Install them?
thanks a lot

AOKP + Franco.

Me too.

Liquid 1.35 and Franco kernel gives great battery life and pretty good options and stability
AOKP milestone 5 & Franco gives options and stability, though the battery life does not match liquid.
To flash these ROMS, go to their threads and download rom and latest gapps(pls check if reqd or included in rom) onto phone.
Reboot into recovery
Take a complete back up
Factory reset
Wipe cache
Wipe dalvik
Flash new rom
Flash gapps if reqd
Reboot phone
Sign into google
Reboot phone
Wait a few mins
Reboot into recovery (if flashing kernel)
Wipe dalvik
Wipe cache
Flash custom kernel
Reboot phone
If using Franco then download the Franco paid app to get the best from the kernel.

at francos site is a link with "/nightlies" and there are a lot dl's.
Can anyone explain for what they are?

Nightlies are the beta version of the kernel updated for testing on a regular basis. Always download the latest one. In that u have 512 gpu (overclocked) & 384 gpu. Try 512 first if it works for you without any issues (try with a game) then great, else flash the 384 version which is more stable.
If you want complete stability then go for milestone 3.

Suggestions for flashing roms

Hi,
I want to install a custom rom to my Gnex. The only thing i have done so far is to change my device model yakjuwx to yakju (I unlocked bootloader and locked it again after the proccess).
I am going to unlocked it again and root my device.
However I don't know from which rom to start. I used to have a i9001 in which there is lttle development so everything is easier.
It 'd be very helpful if u could tell me which rom is the best or at least from where to start..
***sorry for my bad english

Try latest rasbean build! It's superfast and the batterylife i pretty good. One of the smoothest roms I've ever tried. You can find it at fitsnugly.eutoskank.com, select rasbeanjelly, then your phone. Gapps is included I am using it with latest franvo kernel, r268. Awesome combination. But if you want a rom that you can customize very much, you should try out codename android, the nightlies or the stable version! Instead of Franco kernel you can try out Trinity kernel, the colors are so sexy man! haha. But you can set them on franco kernel too if you want.
I hope you find your own combination that fits you needs most
Edit: You can find the Codename Android nightlies here: http://goo.im/devs/codenamedroid/nightlies/cna_maguro Just pick the latest one

I was in the same place as you were a month ago. You'll most likely swap ROMs like socks in a few days or weeks. I've run CodenameAndroid (go for nightlies), AOKP JB and CyanogenMod 10. Of the three, CyanogenMod 10 is the lightest on tweaks and CodenameAndroid has the most, but that's not necessarily a good thing if you don't want to fiddle with everything.
For kernels Franco's kernel is good, get the 384MHz version, 268 nightly -- I've tested it and got better benchmark results if that's your thing.

[Q] Custom Kernel for the Stock 4.2.2 Rom

Just update to Takju 4.2.2 with the stock kernel. Functions are limited with the stock kernel. Any recommedations of which custom kernels that are battery friendly, overclocking possiblility and/or better wifi reception?

ak kernal, fraco is also a great option, but i personally prefer ak.

leanKernel

Just flashed stock 4.2.2 and flahsed franco r365. Seems that the battery is better than before. I will report in the next days.

All kernels aim to give better battery life while not sacrificing too much performance.
Kernels need a little while to settle down so try one out and give it a day before passing judgment and if it doesn't give desired results for your rom and device then try another.

AK Kernel 4.2.2

I've had a ton of success with AK kernels. Morfic and LeanKernel too, but lately the AK ones seem the best for me. I run a custom ROM tho, and I've seen that a lot of folks really like Morfic on stock 4.2.2.
If you're on VZW or Sprint, you may have to flash the GPU binaries to be able to install a true 4.2.2 kernel, otherwise you're phone wont boot and you'll have to reflash a 4.2.1 kernel to get back up and running.

I am new to Samsung Galaxy Nexus (it's my fiancè's phone, though since rooting it a few weeks back we've experienced alot of random reboots, apps not working, random dropped calls, etc etc the list is endless.
I am determined to flash a better kernel+ROM combo away from the stock that it was rooted with (placed on the phone when rooted).
I never did this initially as the phone has 12Gb storage and only 500MB free!! to many photos & video
Do I need to backup the phone (as I would on a S2 [it's what I use and I'm offay with flashing etc etc on that specific device] though not on a Nexus). I guess it'd be best practice.
When looking at a kernel 'franco' came to light as a stable kernel, though what is the difference between 384GPU and 512GPU versions? Can I assume that 'r300' version is or was the last update? as it seems little is supported these days for this Nexus.
I understand I can't ask for recommendations or what's the best ROM, though a guide in the right direction on anything stable preferably current (it's not imporatant as my fiancè just wants the phone to work as it should and won't be changing anything after I mod the phone).
Any advice/info is greatly appreciated.
