NEED CUSTOM KERNEL TO WORK!!!!!

Hi, should the CPU overclock work on standard rooted kernel because it does not seem to work although I updated the parameters in cpu_user_cap, and after reboot the setting is changed back to 0. Thanks

Thank's for the share. What do we do if we ever want to revert these changes? Just re-flash our custom kernel of choice?

Nope, just reboot.?

[Q] How do I flash a kernal?

How do I flash a kernal on my Wildfire? I downloaded Jacob's overclockable one.

Yeah, put it on sd card, boot to recovery and flash it.
Thats what I did, it installed it or something in less then a second but nothing changed.
Kernel information didn't change ? The kernel name should change to a very long name with jacob inside.
No it didn't change, now I have a CyanogenMod rom, with Jacob's kernal but no the one that you can overclock with.
Did you try oc'ing in SetCPU? The kernel is not overclocked by default because then, some users had problems booting with the pre overclocked kernel.
SetCPU is officially available on the XDA Forums. Just perform a search.

I have SetCPU, can you write down how to flash a kernal step by step for me?
I would really appreciate it.
Really, its the same as flashing a Custom ROM. If you were able to flash one, you should be able to flash this as well. (Restart in Recovery Mode, Install Zip from SDC)
BTW, it should show this under Settings > About Phone > Software Information > Kernel Version - [email protected] #1
This will show the kernel is successfully flashed. What is the maximum you can see in SetCPU? Is it still 528?

[CF-Root-S5830 3.7] CF-Root adaptation for Froyo

-------- 29/08/2011 --------
UPDATE:
update.zip (19.61 MB)
update.zip (mediafire.com link)
Changelog:
- ext4 support bugfix
- BLN support
- Only use busybox in /sbin. Now, no one can break CF-Root's busybox.
- Fix some script in /system/bin reported does not work with CF-Root (am, bmgr, ime, input, monkey, pm, and svc).
With deodexed /system/app and /system/framework, USB and WiFi tethering failed to start. Restoring back /system backup, resolve the problem
Is a wise choice to make a nandroid backup before doing filesystem conversion using ext4 Manager.
-------- 26/08/2011 --------
UPDATE:
update.zip (19.94 MB)
Have a critical bug in init.rc, do not use this for ext2/3/4 fs.
Big thanks to ilarrain and koush! Using ilarrain's patch for pm2.c, now I can use my own compiled kernel for CWM4 without recovery boot loop
Changelog:
- CWM v4.0.0.9, ext4 support
- Auto install CF-Root after update, no need to delete /system/cfroot manually
Zeam Home Screen
Firmware Version
CPU Spy Info
-------- 24/08/2011 --------
UPDATE:
update.zip (12.57 MB)
Changelog:
- Using the latest smartass, interactive, and interactiveX source from erasmux
- Fix bug with cpufreq stats, now the CPU Spy can display the CPU Time In State. Possible problems associated with SOD because CPU frequency is too low. May be Sleep Of Death starting from Sleep tO Deep
NOTE:
Remove cfroot directory in /system to force reinstall CF-Root!
-------- 23/08/2011 --------
I am planning to upgrade to official Indonesia Gingerbread (2.3.4 DXKP9), so I have to flash my device to Froyo. But before go to Samsung Service Center, I tried the implementation of CF-Root in Froyo and here's the result:
update.zip (12.46 MB)
Flash it using Galaxy Ace standard recovery.
It has been tested on Froyo DXKC1 and may not be problematic in other Froyo. Everything at your own risk!
Almost same as CF-Root for Gingerbread, except:
- No tiny RCU implementation
- Have smartass and interactive CPU governer, thanks to psyke83 from http://www.madteam.co/
- Default have 32MB zram swap, thanks to psyke83
- Android Scribble 2.0 boot animation from here, thanks to GLa'DOS
- No BLN support
- The CWM part no ready yet
To enabling smartass governer:
Code:
propset persist.tweak.gov_smartass enabled
To disabling smartass governer and back to ondemand governer:
Code:
propset persist.tweak.gov_smartass disabled
Reserved for future update?
one thing caught my interest, since when u implement smartass cpu governor? any chance of it getting to cfroot for kpn/kph? as always, good job
does it support EXT4 ?
I just jizzed to this topic. 2.2 is actually much faster and lightweight compared to 2.3 and with cfroot I might give up custom roms for 2.3 for a while...

Dual booting..wow..as always you come with new and fantastic ideas.
Without reflashing again and again we can have two ROMs.
I wish I could multiboot between different custom ROMs!

Wow.. Just flashed to Froyo to get my GB update.. Much appreciated for CF-Root adaptation.. This make it Ultimate Froyo (coincidentally a nice ROM name XD) before getting my official GB upgrade..

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.

I think faux 123 app is the best for kernel tweaking!
But u can try trickster too!
Since I can't post yet in development discussions I will ask here.
I'm using faux kernel with his app and sometimes I'm having camera problem. I'm using his recommended settings with 384 diskcache, by increasing this like to 512 will I resolve my problem?

I tried all cm11 based roms and roms that are not cm11 based, but are again 4.4.x. All of them were fast, but laggy and not smooth. Will these mods in the thread you made fix the problem and make the phone smooth as 4.3 or even better? Do I need williams kernel, because I tried it and it doesn't improve performance or smoothness. Can't I install mod 2 and 3 without william's kernel?
I need a decryption key to download the GPU performance booster.
