Ziggys Kernels

Well I was looking for a new kernel the other day. I was getting tired of the lag of kingklicks kernels for gps. No offense king, Ive used your kernels since day one of my inc. So I went searching for a new kernel and tried out ziggys outrageous 1.28 lightspeed kernel which turned out to b false (really 1.15, somebody lied to him bout the code). Well on Oct 26th he came out with his new BFS kernel of the source code 2.6.32.24 with being overclock to 1.19. He uses this for bfs which king is still using 2.6.32.15. So far as using it no lag on gps and still get the same quadrant(1680) and linpack(40.223) as kings BFS. If you looking to try a new kernel heres the link. I hope ziggy471 dont mind but mad props to him.

No problem. Im always looking for new kernels and other mods.

did you download the AOSP kerenel or the other one? whats the diff? i downloaded both and they kept on making my phone freez so i went back to hydrakernel.

I have used it on skyraider 3.3.2 now for the last 3 days with exceptional responsiveness and exceptional battery life. I heard people use the AOSP kernel for cyanogenmod and it has been worthy for them too. Difference is AOSP is for people who dont use SENSE UI in the rom. What rom are you using? Also did you clear dalvik cache and regular cache for. I downloaded the non-AOSP.

You can't be using one or the other kernel, either your running an AOSP rom or a Sense rom. That right there tells you which kernel to choose.

I hope this is in reference to the comment above my last one. Cuz I do know what kernel and rom Im running. I use the non-AOSP cuz my sense ui is still intact. NON_VANILLA

This is BFS with HAVS correct? How is the battery life/responsiveness?

Battery life is excellent, best I have had. Quadrant has been in the 1400's consistently (overclocked to 1.113), as apposed to others that are in the 1100-1200 range (including king's) with random moments of greatness into 1400.

Does it lag at all though? I installed King's CFS on CM 6.0.2 and it lagged alot. The 6.1rc2 kernel is very snappy

Nope, no lag. Just a good kernel. I am actually very pleased considering I have suffered with others.

After about 20 or so hours my phone has to be restarted, for some reason there is lag that occurs that can only be fixed with a reboot.
I've had this happen with other kernels too

This is why I stopped using Kings kernals, phone gets stuck at 100% cpu and needs to be reset.
That sucks this kernal does the same.

I just wiped Dalvik and system cache, installed and rebooted. It's seemingly stuck on the bootscreen. How long has it taken to reboot you guys?

Up to ten minutes after wiping Dalvik cache. Hang tight!

It's probably the BFS scheduler... even though the bfs faq says it's good to use in phones.. lol
http://ck.kolivas.org/patches/bfs/bfs-faq.txt
I wonder if our phones would benefit from a higher tickrate when using bfs..

I use the same ROM 3.3.2 as you. I downloaded the non-aosp version of ziggy's kernal. I wiped my cache and dalvik...but no luck with this kernal. My phone just keeps rebooting. See my signature line below and tell me what is different from your setup. Are you using HBoot .92???

im using radio .07.28 and CMR 2.5.0.5 Difference in you your signature

Well, user "Panda Fuzz" is using this kernal okay with my radio version. Hmm.. Must be my 2.5.1.1 version of CMR. People have reported problems with SR 3.3.2 and 2.5.1.1, but not me. This will be the first problem I have encountered with it. Guess I will try going back to CMR 2.5.0.5 and give ole ziggy another shot.

Low voltage kernels

Just rooted. Im new to the droid world, so im curious, can i get a low voltage kernel? A friend has Savage Zen and brags about battery life, but would it be compatible with my default-rooted rom? Also can i backup the kernel? Thanks.
Btw i tried googling but every time i got a good lead the links were dead

If you are referring to a rooted, stock HTC Sense ROM, no, do not use SavagedZen. It is only for AOSP ROMs.
AOSP - Android Open Source Project (vanilla, like on the Nexus)
Sense - HTC's UI
You cannot use a Sense kernel on an AOSP ROM, or an AOSP kernel on a Sense ROM.
(All Gingerbread)
AOSP Kernels:
Tiamat
SavagedZen
Cyanogenmod (kernel)
Godmode
PoonKang
I know that Tiamat and SavagedZen have HAVS and can be undervolted using Vipermod. Cyanogenmod, Godmode and Poonkang may come undervolted, but they do not have HAVS so you cannot adjust it.
Sense Kernels:
Freedom by Lithid
Golden Monkey by Netarchy
ChopSuey by barnacles10
Stock HTC
None of these kernels have HAVS (Freedom used to, but it was causing issues so he took it out). Golden Monkey, ChopSuey, and Freedom can come undervolted by certain degrees, it depends on which version of the kernel you download.
I can't think of any way to back up a kernel except for nandroiding system, but I am probably wrong. Just go into recovery, wipe cache and dalvik and flash a new kernel if you have any issues.
There is a good study guide in I think Q&A stickied, telling all that you need to know about kernels. I advise you to read it. Link: http://forum.xda-developers.com/showthread.php?t=894880

You can usually recover a bad kernel by flashing to back to the stock kernel and wiping cache and dalvik. Its usually worked for me, but depends on how much the custom kernel changed things.
To OP, go check out Kernel Manager in the market. It takes a good amount of the guesswork out of kernel flashing.

I say go with chopsuey 9.1 ill say its really good left my phone off charger for 8 hours while i slept was at 41% before and when i woke up it was still at 41% i mean does it get anybetter than that

Thanks for the help. Really in depth and helpful advice . Using freedom aggressive kernel now. Still testing to see if it helped. Great forums.

Running stock rom, rooted, which kernel suggested?

Kind of burned out of flashing all these different roms. Dont get me wrong, I appreciate all the hard work everyone is providing for us. But I am burned out and wasting hours of my day flashing rom after rom etc.
So I went back to stock and rooted. But I did want to see if there was any advice on any kernel out there that I should be running with the latest stock build?
Thank you,

Der Kernel - Trinity. Comes in high OC version a96 to lower of but slightly irregularities a110 and many more. YMMV but this is a solid, customizable kernel.

Is there a secret to flashing the trinity kernel?
I reboot into TWRP, wipe cache and /dalvik 2x (old habit) flash Trinity, reboot but still shows previous kernel under settings?

whats your previous kernel and whats in say in kernel version? btw, you dont need to wipe anything when flashing a kernel. anyways, only if you are coming from franco kernel you have to reflash your rom with trinity kernel(flash rom, trinity, reboot). this is because franco kernel uses its own ramdisk(frano kernel tweaks are in there). trinity and just about every other kernel use anykernel which grabs the roms ramdisk usually(unless you had frano kernel). so you want to flash your rom, then trinity, then bootup to resolve the issue. after that you can just flash the kernel. remember, no need to wipe a thing when flashing kernels.

[Q] Recommended kernel for Paranoid Android

Anyone have any recommendations on a good kernel for Paranoid Android? Franco, Faux or the default? Thank you.

Franco. Another good pick is Trinity (found here: http://derkernel.com/mako.php# )

Is there a resource somewhere that has comparisons of the kernels? Do people just go off of the reputation of the dev that makes them, how do we know what they do?

No there are no comparisons. All kernels are relatively early in it's releases at the moment. I'd say they are pretty smooth, I go off based on my past experiences. On Galaxy Nexus, I've used between Franco and Trinity, mainly Franco and bought his app so I use Franco kernels only. But all kernel developers are talented, some phones just like some kernels more often.

Yes, there is a comparison! Check this out @ http://forum.xda-developers.com/showthread.php?t=1889571

That's for the Nexus 7...

I personally have used PA roms with 3 kernels:
- probuild in rom - was good, but not as smooth as my experience on stock rom
- Franco (r21 and r22) - i have experienced some lags so decided to try another one
- Matr1x (3.5) - currently am using this one and it's very fast and smooth

After deciding I wanted to use my Best Buy warranty and dropping my phone in boiling water (interesting side note, I took it out after about 20 seconds, still worked fine!) I just got my new replacement. Graciously enough it came to me unlocked. I used Wug's toolkit to root it.
I flashed PA, successfully rebooted. Downloaded Franco Milestone 6 onto my GNex, booted to recovery, wiped partition cache, wiped dalvik cache, flashed the Franco zip, and then rebooted. I've tried this exact same procedure three times, and every time my phone gets stuck (waited at least one hour on the boot animation. I'm back to PA w/ stock kernel, but would really like to get Franco working, any ideas/advice?

[Q] Custom Kernel

Hello,
I use SM-N9005 4.4.2, Baseband ver. N9005XXUENC2, Kernel ver. 3.4.0-1168347, Build number KOT49H.N9005XXUEND5.
It's a rooted, stock ROM somewhat modded with Xposed, Android Tuner app etc.
I'd like to flash a custom Kernel which will allow overclocking, eXtended battery life and some other neat features I hope more experienced XDA community will recomend.
So, what Kernel would you recomend as a mix of stability and performance for my stock TW rom? I am fairly inexperienced in these waters. Are Baseband version, Build number etc important when deciding on a Kernel?
Any advice would be welcome. Thank you in advance.

Try n3 by wootever, sneakykat and leankernel (last doesn't have so many features but is great for battery & performance) and my personal favorite ael kernel of course.
The kernels are pretty easy to flash just put on SD flash and wipe Cache & dalvik. So don't worry if you don't like the kernel just flash another one.
One more thing don't put two different apps for kernel settings (like Synapse & Trickster) on the device cause that may cause conflicts. Have fun testing

Is it really necessary to wipe cache & dalvik? I've read in several posts that it is not required as there will not be any benefit.

To quote Hacre, an excellent dev on other Samsung devices - wiping cache and dalvik for kernel flashing is like filling your car tires when the gearbox is ruined...

That is pretty hard to answer cause I do not know what settings you prefer. (Performance, battery or a mix of both). Download Trickster from app store or set cpu (for last you have to pay though). At first I would try to set just governor and I/O scheduler. In the link you will find some information. Got helped not too long ago

No for Benchmark maybe but most of the time the phone will crash then.
Personally I take 22565600 as max and 300 min with intellidemand governor and deadline scheduler but every phone works different that's also why you won't find any "perfect" kernel or governor.

how can I flash the kernel I tried CWM to flash the zip file but it doesn't work please help me to find my solution
