Hey guys, new to the forum and the Vibrant, and i first want to say i love the setup and this forum is insanely informative on its own. Im fully rooted/themed/tethering/modded and the only question ive had to post was about icon .png size haha. so thanks for setting up a VERY efficient forum.
now my question: do i have to install a custom kernel in order to overclock/underclock? I installed setCPU and it wont let me scale past 800mhz. Also no presets, its just says to use conservative scaling for GalaxyS phones. No thank you, i wanna push this thing! Running stock kernel and firmware. Thanks ahead!
I believe you will need to flash one of the many kernels that fits what you want it to do, you should be able to under clock android if your phone is rooted but you will need a new kernel to overclock it.
when you install setcpu make sure you do auto-detect. since you already have it installed, hit menu->device selection->autodetect speeds
on a stock kernel you should be able to set max to 1000000mhz. With the Vibrant ALWAYS LEAVE SCALING TO CONSERVATIVE or you will have freezes.
To get past 1000000mhz you will need a custom kernel, I have been happy with both King's and JAC's. Just download one of their kernels, flash it through CWM, reboot, and run setcpu again and make it autodetect your speeds, from there you should be able to clock up to 1200000mhz
Good luck.

I'm not very familiar with kernels, so naturually im a little hesitant. What else will it affect?

It all depends on the kernel you flash. If you flash voodoo it will change the way the phones file system works. However if you just flash JAC's OC/uv kernal it will OverClock up to 1.2 ghz and UnderVolt some of the midrange frequencies to help improve batterylife. I reccomend reading up on his threads before you attempt these flashes. He has made the procedures to flash these kernels very easy to implement. Good luck and happy flashing! (That just sounds wrong!)

Hello,
I am new to the android world. So far, I have rooted and installed the CM7 alpha to my phone. I now wish to change kernels to improve my battery life. I am planning on using the normal kernel for CM7 from here: http://forum.xda-developers.com/showthread.php?t=1021404 . To install it, I realized that I flash it in recovery. Is that all that is needed to be done for it to work properly? Do I need to set it up somehow? The thread discusses different governors for the kernel, how are they selected?
Thanks!
I figured it out and now have setCPU installed. Working good so far.
you dont need setcpu, in cyanogenmod settings go into performance and you can default the governor, etc there.
Good to know, thanks!
hello,
I'm using the official lg rom v2.2.1 that came with the phone. I wanted to update to cm7 but I read about the problem with the BT wich I must have. another thing is that I'm using hebrew and I need it to stay that way.
The thing is that the touch screen is very bad and lags a lot.
If I will upgrade only the kernel what will be the affect on the phone and how do I know what is the best kernel for my version ?
In general I want to fix the touchscreen bug and to OC the phone.
thanks for the help.
If you just want to overcome the touch screen bug then I would suggest using Der_Caveman's Kernel, it is quite old but is usable and removes the touch bug and enables OC.
The kernel wouldn't change any outward appearance of the phone, except maybe increase the quadrant score a bit. If you really want a good performance boost as well then try franco's kernel. Since you are using the stock rom it is recommended to take a nand backup before flashing these kernels. And a kernel doesn't change the system language AFAIK.
Thanks for quick reply. will these two kernels good for froyo 2.2.1 and are there known bugs that I should be aware of before updating ?
As far as read the franco's v18.1 is for 2.3.3...
I have never used Der_Caveman's kernel, but it is bug-free AFAICT. And in the link that I have posted above, franco kernel is available for both froyo and GB. Download the version that says "franco.Kernel v8.1 CFS", it is for froyo.
And as I said earlier, since you are on stock rom it is advisable to take a nand before flashing a custom kernel.
i used dookmatt's kernel which was really good for me(flashed it on stock 2.2.2)...i had no touch lag, no bugs. that would be my recomandation
also dont forget nand backup is holy!

Can I OC with this one ?
OK, I flashed Der_Caveman's Kernel and so far it looks good. the touchscreen is better and I OC to to 729 using setcpu though I cant tell the difference in terms of the speed.
how can I tell if its really 729 and not 600 ?
thanks.
yes my O1 ran at 787 mhz and it was darn stable(at 800+ i had frequent freezes and reboots when launching apps). i also had a friend of mine install this kernel and he's happy with the "new" phone i made
quick system info on market...shows cpu speed
You may look at info tab on SetCPU, it says alot about your device, CPU (frequencies and features), battery and so on.
And you can have SetCPU widget on homescreen as well, which shows current freq, min and max frequencies of the governor you're using
Regards
I'm finally jumping off the deep end into the world of flashing my Photon for the first time!
1. Which ROM do you recommend and why?
2. Does unlocking the bootloader still kill 4G?
3. Does the CM Recovery have to be manually installed or can the ROM Manager from the Android Market be used?
4. Common problems/issues to be expected?

1. I've tried both Homebase and Alien and they are both good. Homebase has Shabby's kernal, so it will run a little faster and battery life wont be as good as with Alien.
2. Yes
3. ROM manager is still not supporting the Photon, check out http://forum.xda-developers.com/showthread.php?t=1250697 for step by step instructions on how to do all the flashing and unlocking. These videos helped me out a lot.
4. No problems what so ever, but i'm only speaking for myself.
Enjoy!

Thanks for your responses! Once you've flashed a new ROM, I'm assuming you have to flash back to stock to get OTA updates, right?
Which ROM are you currently running?
Which one do you ultimately prefer so far?
What advantages does it give you over running stock?
Does using something like Go Launcher EX on a custom ROM kinda defeat the purpose?

I'm currently running Alien. I like the vanilla gingerbread theme for it but for what i do i cant really tell that much of a difference between this ROM and Homebase. if you want the overclocked cpu, go with homebase. it uses Launcher Pro as an overlay but i'm assuming you can use whichever launcher you prefer. the specs for each rom are listed on their respective thread pages. some advantages are the custom kernel, wifi scan frequency for battery life, no bloatware. Its not that hard to flash ROMs with CWM once you unlock the bootloader and root, so i suggest flashing both, getting used to them, and then seeing which one you like best. i will probably go back to homebase because i like the OC kernel and they have an update that reflects the current software OTA.

Can you see a noticeable speed increase in with the OC kernel?
Does the battery gain from the wifi scan frequency balance out the battery drain from the OC kernel?
Any problems at all with the Homebase ROM other than losing 4G?
.1 Ghz isn't that big of a difference IMO plus the launcher the ROM uses is pretty fast to begin whith. you may lose probably half an hour of battery life from OCing. its a very good ROM and i havent had any problems with it.
just wanting to know whats the best way to install superclean 3. currently on a debloated rom ed01.

Change what setting? The kernal will come with its default settings when you flash it
ok, i just was confused, since i have seen alot of comments about changing their voltage setting to over clock and under clock. i wasnt sure if they had a default automatically. kernels are the one thing that confuses me.
Kernels will have default voltage settings and (usually) are not over, or under-clocked by default. If you want to change those values you'll need an app like voltage control.
thanks i'll look into it. would it be best to read through the posts under the SC3 Rom to see what would be a good voltage setting to run with?

I have been running SC3 milestone2 (AWESOME btw) for a while as my daily until the bugs get worked out on ICS. I use Leankernel however because my phone had display (color and lines) with KGB. LK comes overclocked at 1.2ghz. It is fixed, whereas KGB can be overclocked more (up to 1.7 but you most likely wont get past 1.3 or 1.4 and be stable).
If you want to flash kernels an wasy way to do it is with SGS Kernel Flasher (free in the market). It will back up you current kernel so it makes trying different kernels easy.

what bugs are you experiencing on ics keeping you from using it as a daily? im running ths 6.1 with no major issues at all. only mi.or thing i notice is the browser will hang up on a white screen sometimes but a refresh fixes it.

thanks i will look into that app and the kernel u mentioned. i have been meaning to look into overclocking but still new at it and want to be careful.
Hi, sorry if this is in the wrong section, I just posted here because it happens to be on my SGS2.
Im trying to overclock my phone but i've run into a problem.
I'm currently running JellyBam 3.0 on my SGS2 (rooted ofc) and SetCPU says my kernel is Linux version 3.0.15-CM-gf76e4eb
I've downloaded Tegrak Overclock for my phone and tried to overclock it and I first tried to "Load overclock module", where it came up with an error Failed to run insmod! <0x7f050008> err1 code=2
After researching it appears that my kernel is not compatable with overclocking or some sort of thing. Can I just flash any kernel onto my phone? Without affecting my JellyBam Rom. If so could you please suggest a kernel or how to go about finding a suitable one.
Thanks for taking the time to read my post,
hoping for help.
I don't think Overclocking is reccomended for our S2. It won't make the perofromance of the phone any better since the S2 is very solid and with dual core chip it cannot be better than it is, but however if for some reason you need that you might do it, I don't know which kernel allows you to do that though. Sorry.
Why don't you ask in the Jellybam-thread? I thought there where several kernels that work with Jellybam, but I haven't used the rom for a while.

use siyah kernel with ex-tweaks app. But its not recommended to OC. It will only drain your battery
overclocking will kill your phone. dont do it. Its not like a computer you can not give it extra cooling.. It will damage the phone and damage the battery with the extra heat. What a faster phone try a custom rom. Remove apps you dont use and removed auto task killers they slow your phone down.
Thanks for all your replies. I realize my phone is already very powerful but i didn't want to overclock it for desktop use or normal usage but rather because i read everywhere that my phone lags on the games i was downloading such as bat man and modern combat4. Thought i could improve the performance during that.
But i thinki will just rather not and deal witha little lag. I don't exactly have money to spend ona new phone.
Again thanks for all your replies.
I prefer flash one good kernel: siyah, dorimanx, because OC drain too much battery. And u can try OC because those kernels have OC options
