How to use SetCPU?

I just recently rooted and started loading ROMs that support SetCPU to overclock. I was wondering if there was a way to overclock the Sprint HTC Hero without running someone's rom (like Fresh Toast)? The only reason I rooted was to make my phone less laggy but I hate all these ROMs/Mods because most of them are broken/incomplete and hate how I always have to wipe my phone to update//change ROM.

Since lately I've been trying to do the exact same thing, I should be able to help.
You're going to have to root your phone (which you obviously already have done) and flash a kernel that allows OCing.
this is the only one I know of on this site: forum.xda-developers.com/showthread.php?t=690238
However, that one did not work for me. (I was always stuck at the HTC boot screen). You should try it though, and if it doesn't work PM me and I'll PM you a link to another site that had a kernel that worked for me.. since I don't know if linking to other sites is allowed.

Sadly, the stock rom cannot be overclocked (for pretty obvious reasons.) Give Fresh Toast a try. I am running it without any problems. Toast's custom kernel makes it super fast. I also recommend using overclock widget with these settings:
Screen on: min: 576000 max: 768000
Screen off: min and max: 245800
just be sure to check "use my frequencies" and hit "detect frequencies" so the kernel does its job.

The stock ROM CAN be OCed if you flash a custom kernel that allows it.

I am currently running Fresh Toast, but after about 2 days of using it with SetCPU at 768000 max and 19200 min, my phone starts to get as laggy as before. I dont really know how to use SetCPU maybe I'm using it wrong, I just tapped the option where it chooses for you. Let me know what settings I should have it on if these are wrong.

How do I flash a custom kernel? What is a custom kernel? What is a kernel? Lol sorry, I am new to this.

Well that min. is way too low imo. I use 633600 as my min. and it's fine.

You flash it the same way you flash a ROM I believe. Use the "flash from zip" or whatever it's called in recovery. Put the zip in the root of your sd card. You're going to want to put stock 2.1 on it again first though I think, unless you want to keep your current ROM.

lol i know how to flash roms and where to put em and stuff but what exactly is a kernel?

ok so if i use one of these: http://forum.xda-developers.com/showthread.php?t=684838 or http://forum.xda-developers.com/showthread.php?t=690238 I can use the stock Android 2.1 AND overclock?

a kernal is the foundation of an os. all the system values are stored there, its like...the engine of the phone;from a software perspective.
id highly recomend darchworks. by far the fastest, and i promise youll never need an oc tool. just hope you dont mind kissing sense goodbye
happy flashing

im happy you liked it, because its the best jk!
you should know that in most cases, if your experiencing lag, sense is usually to blame. why dont you give zens slide port a go? sense with a whole lost more options and its definatly overclocked...iht it was the fastest sense rom ive ever used.

Kernels and Sense

I'm currently on modaco r21 sense I want to improve my battery life how can I go about doing that? Can I flash a kernel if so which one?

Flash intersectrave or pershoot kernels. Try all the kernels and see which one fit you best, no harm to your phone if you keep on flashing kernel. Dont ask question in this forum because its for DEV only. Use the general forum for all your question.

Hi.
You can improve your battery life by :
-reading forum rules
-usin search button
-poosting in good section
-be polite
F.

IntersectR doesn't support Desire Rom for the newer 34 Kernel.
The last Kernel is 33.5 back in late May that was updatedt that is undervolted and will wor fine on Desire R21. Run the 925 CFS version and you are good to go.
4th Kernel down.

Thanks alot tech I really appreciate it, was actually having some trouble trying to figure out which one was right for me I want to improve my battery but not give up to much speed, thanks again tech...
I was also wondering how I can make my phone run a bit faster I have setcpu an its at 768MHz I was wondering how I could improve that without frying my phone, don't even know if its possible to fry your phone but yea...

[Q] Samsung Galaxy S Overclock PLEASE READ

This thread is somewhat different from others. I am fully aware that overclocking requires a custom kernel however with the Application "Galaxy Tuner" my CPU on my SGS i9000 can go 1.2GHZ with a custom Voodo Kernel not supporting Overclock. I am not sure what method the guy uses and he only allows it to be used 2 minutes at a time, so I was wondering if this would be just as risky / safe to do as going into a new kernel and doing such.
If the first is not possible and I would have to use a custom kernel as it is safer, please PM me some kind of contact information as I am afraid I will break my Phone as I use a custom Voodo kernel + DArkys EXTREME ROM 9.X

Still need to know wheter or not it is safe to overclock the way the application "Galaxy Tuner" does or if its SAFER to do it with a custom OC'ing kernel.
If last, I need some help over Skype / msn

I expect an answer when so many viewed this thread....

I wouldn't expect anything, just because people like me view it doesn't mean we know anything about it.....why don't you email the author of the app.

Exactly, views don't mean answers! It can be frustrating seeing a lot of views and no answer, but you must acknowledge that viewers may be looking for the answer themselves or just plain don't know. Be patient.

Well. Still, I am wondering about the overclocking that The application uses (Galaxy Tuner) because it manages to overclock a phone WITHOUT a custom OC'ing kernel. Hence i am wondering if it is just as SAFE to do as using a custom kernel.
If not, I need some guidance as I dont know how I can switch my kernel and update my ROM

The code to overclock existed on stock kernel sources apparently, it was just commented out.
When OC in this app is enabled, the CPU governor is changed to performance, and the clocks were changed. So I'd wager it's equivalent in terms of safety to a custom kernel.
Why only do the above for 5 minutes at a time when a custom kernel allows you to always have an overlclock? Just use a custom kernel..

I'm using a custom kernel to overclock to 1.2ghz and my battery is exactly the same as it's always been. I'm also underclocking to 100mhz with setCPU when the phone is idle so that's a big help. It's perfectly stable on mine but CPUs can differ so I suggest that if you do flash a custom kernel with overclock that you start lower and stress test just to make sure there are no issues. Also, don't save any voltage control settings as default until you have applied and stress tested.
Also, make sure to keep a spare kernel in zip form and always have backups.

I use super optimized kernel. Though I am looking for a 500-1000 HZ OC kernel. Any suggestion?

I don't know what method this app is using, but just due to my own paranoia I would say using a kernel with OC is safer. Too many horror stories of apps bricking phones due to small errors or badly written instructions.
Beyond that, it just takes experimenting. I am currently using DamienGTO's Ultimate Kernel OCed to 1200 and have had no problems with it, but there are a lot of high quality kernels available down in the Android Development forum. I suggest you install SGS Kernel Flasher from the market (a great app, makes kernel flashing painless and dead simple), download the newest versions of each kernel that says it supports OC, and spend a day flashing and testing. Just remember to disable any OC/UV, lagfixes or tweaks between flashings.

[Q] Overclock Nexus One Gingerbread?

Hi, I've tried searching but what with the 30 second search delay and all the outdated threads, I'll ask afresh.
I have a rooted N1 with Set CPU running. Is there a simple way to overclock it, and to what speed?
What settings are recommended?

you need a custom kernel, than you can put your clock speed up to the speed, the **** allows you ( 1113, 1150 or 1190 Mhz)
my nexus can handle 1190 mhz, but there are not many kernels for this speed
have fun with your N1

Sometimes misspellings are both funny and disasterous!
Most people say 1150 is the most you should run at for 24/7 use. I use 1113 on CM7 and the phone seems perfectly happy with this. Whether there is any noticable gain though is another matter

Thanks guys. Is there an easy guide to the recommended new kernel?
Will replacing the kernel lose me any data or SD card stuff or is it safe?
And will new updates like 2.3.4 come in from Google OTA?

Take this rom and you are happy:

2.3.4? i can't see in the future but why shouldn't it come for our Nexus One
and sorry for my **** :s...i meaned cook of course

Will this overwrite my data?
I'm confused about the difference between your suggested new "ROM" and the new "kernel" which is actually all I need for overclocking.
Do I have to get a new ROM to get a new kernel, or can I just get the new kernel on its own.
I like to keep things as close to stock as I can.

I believe all is required is that you are rooted. Then you can flash a new kernel. Think as a ROM as a new browser you would use to use your phone.
And no flashing kernels do not erase any data. HOWEVER always, always make a backup before flashing anything. Better to be safe than sorry.

Thanks, so the best new "kernel" (rather than ROM) to give me overclocking is?...

Most of the kernels floating around out there are compatible with and made for CM7 or one of its Kang's / and or variants. If you are running a stock ROM, a custom kernel may not be compatible with all of its features, ie the camera may force close etc...
Do a NANDROID, flash a custom kernel and then test. If certain functionalities are gone, restore your NANDROID and either live with stock or try a custom ROM.

Try Kernel Manager from the market

So I flashed CM7 but as predicted the camera doesn't load.
I wasn't able to take a nadroid backup. What else can I do to revert the kernel?
Please help.

Galaxy Mini crashing all the time? [Solution]

Hello, first of all sorry for my English. And now to the point, when I was using stock rom I had no random crashes and freezes. But the stock rom was like made of wood. There were no customizations ant mostly important volume music controls. So I tried many custom roms. All of them where instable for some reason. I was having about 10 crashes and freezes per day, really annoying. I was trying to find solution in Google, there were no helpful answer... So I was changing roms over and over, was trying to find stable one. No success, then I realized that most of them use same kernel (I think it’s squadzone's). So then I thought that maybe if I find somewhere a different kernel it could be fixed. And wola, [Overclock kernel 806 mhz Galaxy Mini] fixed all my problems. Now I run my galaxy on 806 mhz and there are no stability issues any more (most of the roms works with it, but for now I am using cyanogen mod 7.2). I am not sure does someone else has this problem, but if someone really does, try this kernel. And I want to ask developers maybe they could find what is wrong with those other kernels? (It took me about a year to find solution, I don’t want that someone else suffer this :laugh
P.S I found that Cyaogenmod 7.1 kernel is stable for me too, but it has no good OC feature.

who created this kernel anyways?? cause it's not squadzone's work...

I don't know, found it accidentally.

did you always tried to overclock your SGM on every custom rom you have used?

You think I wouldn’t have thought about this?? Of course I tried to decrease clocks, I tried everything.

make a backup of your Boot.img to flashable zip before try something like that.

If you over clocking it too much yours processor can't handle that. Every phone have his stability zone.
