I just got the Captivate yesterday and I'm in love with it. I've been modding my Backflip for a while and I'm fairly certain I know what I'm doing. I've been trying different ROMs and I've currently settled on a rooted stock 2.2 ROM.
I want to change my kernel though, so I put my phone in download mode and flashed the Galaxian kernel via Odin, it finished and then my phone started boot looping. So I one clicked it and tried again with SGS flasher, boot loop. One click restored, tried with CWM, boot loop.
I've also tried Talon, Speedmod, Setiron and a stock kernel with all 3 methods. Nothing will flash without boot looping.
That kernel is designed for reoriented i-9000 roms

What about all of the other ones that were supposedly for 2.2 ROMs?

It needs to be a true captivate 2.2 kernel a lot are i9000's you just need to read the op for whichever kernel you are looking at thoroughly. 90% of the time the dev states if its an i9000 kernel.
The speed mod kernel here, forum.xda-developers.com/showthread.php?t=893880 SHOULD work just make sure to wipe cache and dalvik cache in recovery after install and it should boot.

You will have to read the description in the first post on the kernel you want to install, and the kernel you were installing was a gingerbread kernel

Yeah. You were trying to install a gingerbread kernel on a froyo ROM. That won't work.
Thanks guys! I think I downloaded the wrong version of SpeedMod the first time, it worked this time. Firstly I didn't know that the difference between i-9000 and i897 meant that much. Secondly, I'm not really sure how to read the kernel topics, they're confusing to say the least :S.
I'll learn sooner or later but thanks for your help everyone.

Yeah some are very confusing the biggest help Is to learn the difference in firmware revision codes. Most captivate roms/kernels begin with k. like kh3, kf1 that sort of thing and from what I remember j is for I9000 eg jv1 etc...

Hey guys!
I recently got a Rogers captivate (I896) and have been playing around with it lately... Currently it is running CM7... I followed these steps to put Cyanogenmod on my phone (http://wiki.cyanogenmod.com/wiki/Samsung_Captivate:_Full_Update_Guide) I've been reading up on kernels, and am pretty interested in changing the kernel... But when I checked the kernel, i had a kernel named 2.6.35.7-g8f2a88c-dirty [email protected] #1... I did some searches but it came up empty... What is this kernel?
I've been looking at Glitch, hoping that it would improve battery life...
Thanks for helping me identify!

With a few quick searches it seems that that kernel is the one that CyanogenMod uses as the stock kernel, I don't have CM7 on mine but take a look in the dev forums and you can see other kernels and read a little about the differences. Then choose the best one for you. And if it turns out it isn't the best one for you flash another.

KK, thanks... I was wondering why it was like that... Does installing roms influence kernels? It shouldn't right? When I followed the instructions it said I was installing the SpeedMod kernel...
Well, thanks for your help! Now I need to look for a different kernel... My battery life is only around a day, if i let it idle.... Thanks again!

Your welcome and hit the thanks button. As to your other question most roms will come with their custom kernel cooked in some will use the stock kernel but almost all roms will change your kernel when you flash something new. Kernels and roms are completely different things but you can't flash a ROM without a kernel. But you can flash a new kernel without flashing a new rom. Just make sure that you read read read. So that you don't end up bricking your phone.

What you're asking is generally regarded as not possible.
All things being equal, OC will use more energy, heat up your phone and shorten your batter life.
S7 is already fast and good on battery from what I read.
You can make your battery last longer by dimming your display, turn off your data sync or background apps when you don't need it.
It may be easier to buy a $4 spare from china...they're pretty good for the money
I am new to android and trying to figure things out. I notice a lot of the ROMS say that they don't have a kernel. Do I need to download and flash a kernel as well as a ROM? What would happen if I just flashed a ROM? I was looking at Eclipse and Tweakstock as possible options, but both say they don't come with a kernel. I am running the stock kernel (2.6.35.7-EP4). What would happen if I flashed Eclipse or Tweakstock with the stock kernel? Would it work? If I do need to get another kernel, any suggestions?
Why would you look at Eclipse? It's extremely outdated. Also, TweakStock has a version with a kernel in it.
Sent from my SCH-I510 using xda premium
Eclipse was the only ROM i noticed that said TW4. I wanted to be able to resize widgets and I know u can do that in TW4. As for the Tweakstock, I see now that there r multiple versions, though to be honest i'm kinda not sure which one im supposed to use. I think the last one with the experimental repacked EP4D kernel, but im not entirely sure. Again, I'm new to all this. Been on stupid windows mobile for the past few years, so i apologize if this is "no-brainer" stuff.
if you're on stock then the repack kernel should work fine

i was trying to flash for the first time my samsung infuse with the serendipity VII rom, so i flashed the kernel with sgs flasher and when the phone rebooted it stuck in the samsung screen and it has been that way for like an hour.. i know that it takes time when you flash the kernel but i think something is wrong.. any suggestion or solution?
What kernel did you flash
Sent from my SAMSUNG-SGH-I997 using Tapatalk
Did you flash a froyo kernel or a gingerbread kernel.... S7 is a gingerbread rom so therefore you have flash a gb kernel. Use three finger combo...vol up,vol down and power to boot back into recovery and reflash your rom

If D's suggestion doesn't work... odin. You'll find a big long list of important info stickied call super thread in the Dev section.
Hello,
I have read about kernel for a while.
The phone I have is Verizon Samsung Galaxy s3 I535 with Darkhorse them SynergyRom 1.7 installed. I do not install Kernel yet. I read lot of forums and quite not sure which kernel to install into SynergyRom 1.7. Don't want to have kernel mixed up causing bricks. Have Nandroid backup two back up one on phone and one on pc. I have read this Kernel requires busybox and ez recovery?
I await your reply.
Thanks in advanced!

I am using Imoseyon BETA leanKernel on Synergy 1.7. Use EZ Recovery to flash CWM 6.0.1.0. You do need to have Busybox installed. Let us know how it goes!
Your phone will look like it's turning on 2x every time you turn it on/reboot. I believe this is just kexec doing its thing.

Yes it will boot twice it appears like a boot loop but its really kexec doing its thing...I personally use inviableks kernel...can be installed with ez recovery

The last time I used invisibleks v2 it did not auto reboot? You had to reflash on each boot in recovery..has it since been updated?

I have not had any problems with needing to reflash it I always just reboot recovery and it loads the kernel but does not go into an actual recovery since it is hybrid

Works as charm! Was scared first but it went well! If I want to install different rom will have to flash stock kernel before flashing different roms?
Thanks!

Nope! When I flash new versions of Synergy my kernel goes back to stock. Just remember if you chose Imoseyon's kernel from my link above that it is only for TouchWiz roms.
He has posted an AOSP version over on rootz as well.

+1 I flashed this kernal last night and so far have seen a huge improvement in battery life (not that it was bad in the first place). Overall it seems snappier as well.
