Hi
I like this rom
http://forum.xda-developers.com/showthread.php?t=1423058
And this kernel
http://forum.xda-developers.com/showthread.php?t=1398910
1st question
Are they compatible ?
First i will install rom with recovery then flash kernel with flash tool .. Is that right ?
I am afraid to brick my phone help me plzz pro users
2nd question what can i do with overclock ..another thing like increase cpu speed and is that dangerous?
3rd question at kernel i read that i can make my cpu 1.8 ghz and in rom i read that i can make cpu 1.4 .. My official cpu is 1 ghz how it can be like that
I always read that doing that will brick my phone(hardware) or decrease cpu life
I am afraid to do that .. Some users crash their phones with that and others r relaxing ..
Help me plzz tell me the risks and how to ignore ..
Waiting for ur answers and sorry for stupid questions and bad English

If you install the Gingerbread, Android 2.3.X version of the kernel and this ROM, then it will be compatible.

No, on stock ROM you won't have Recovery, so first unlock bootloader, then flash kernel and then enter Recovery.
Recovery is included in the kernel.

CPU works at certain rate of pulses, the amount is called clock. By default, a CPU works at 1 GHz, that means 1 billion pulses per second(comparison, human heart about once per second).
Overclocking means making the CPU work at higher rate. When CPU works at higher rate, it gives out more heat, which can be dangerous to the CPU. If it gets too hot, it might just melt itself or another parts of the mainboard in your phone. That's how phones get f**ked up

You can set your CPU clock yourself. Depending on kernel, it can be max 2 Ghz or 1.8 or whatever. You can choose any amount between 0 and that max. By default, on stock phones, CPU works at 1. By using a specific app and custom kernel, CPU will be told to work at higher rate. Result, read the text above.

Yes, correct. Overclocking does decrease the life time, uses more battery and is quite dangerous. The real speed boost is actually small and is not really worth it.
Overclocking is not obligatory, you can do it if you want, but you don't have to. I highly recommend not to overclock your phone.
1) I don't know. Check or ask in the ROM's thread.
If your bootloader is unlocked, install the proper kernel and then flash the ROM from recovery.
2) Overclocking is always dangerous. Not only if you overclock to 1,8 Ghz. Also 1,2 could damage your phone. I'd suggest you not to overclock, but it's up to you.

I think i will not overclock my phone .. When i finish installing rom and kernel my cpu will not be overclocked right?
Because i read there is over clock in both

Common misconception.
Knowledge about hardware + careful steps = safe overclocking.
Anyway, I dont get the idea of OC'ing smartphones.

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.

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!)

Moved to Q&A
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

Hi guys,
I've learned alot from this forum. I wanted to speed up my Neo V so I just finished Unlocking my phone and flashed to XNEO kernel V2 for overclocking capability up to 1.6ghz.
I downloaded setcpu and started testing.. Now the problem is my phone freezes and reboots itself when using a freq. higher than 1.4ghz.
I've seen ppl overclock this phone to 1.9-2ghz? I know that this is too much for daily use but i really want to fly 1.6ghz stable.
What is the cause of this? Do i have a bad cpu? Do i have a bad kernel? Or do i need to upgrade the voltage a bit? how can i do this?
Thank in advantage!

Well these actually look good. From here there are two obvious options:
1.It's faulty hardware, not much you can do about it
2.It's a bad kernel, so try switching to a different one for testing purposes.
Let me know how it went
unlock your bootloader and try another kernel
Thank u for replying! Im gonna try a diffrent kernel when im getting home tomorrow. Maybe someone can recommend me a solid kernel for a neo v with stock ics 4.0.4? (bootloader unlocked)

I tried another kernel and my neo is flying @ 1.6ghz without problems thank u all for replying!
Still got some questions though..
1)Is 1.6ghz still pretty safe for daily use? Im using smartassV2 governor so it wont run at 1.6 ghz the whole time.
2) Since i upgraded to ICS most of my games are lagging and some don't even function properly. I think don't function properly couse they are emulated in a gingerbread environement to run in ICS. So I want to return to gingerbread OS.
DO I just have to flas the stock gingerbread rom with flashtool and afterward flash a compatible kernel for gingerbread for overclock?

Clock speed really depends on your usage. For a gaming phone, 1.6 is pretty decent I guess. I have gone up till 1.8 for a couple days without any issues.
Regarding downgrading, if you want stock then simply flash the GB FTF file with flash tool. Or else, flash a GB kernel and then install your fav'te ROM from CWM.
Thanks for replying
I flashed GB, rerooted using CWM, flashed a solid kernel.
My phone is now in top condition lol. thanks all!

you cant overclock without a custom kernel.
you cant have a custom kernel with locked bootloader.
therefore, you cant overclock your phone.

No such thing. Each and every cpu is different so u need to experiment yourself. But seeing the msm8255t in arc s which is the factory oc'ed of our msm8255 running at 1.4ghz by default, i'd say 1.4ghz is the "safe" mark.
Hi all...
2 days back i unlocked my bootloader
Now i have FXP 137 Kernal and using Jelly venila based on CM10.. but Prior to that i took a nandroid backup with Rage kernal and Stock ICS 4.0.4 with .431 firmware..
*Now if i restore the backup will kernal also be restored or simply the Rom???
*All kernals work on any roms or is there any limitation in it??
*Can kernals be flashed with phone itself (like flashing custom ROMS in CWM) without needing pc???
*Are there other Recoveries like CWM ? if so what is their advantage ?
*after a full wipe/factory reset, can recovery be accessed just by flasing kernal only?
*Clocking depends on kernal or Rom or both??
sorry for asking too many questions..these are in head..
i would be realy grateful if anyone answere these....
thanks in Advance

*No kernel won't be restored, you will have to flash it manually
*Not all kernels are working, check the thread of the rom, which kernel is recommend!
*You need a pc and the easiest way to flash the kernel is via flashtool
*Yes, for example Amon Ra, but I don't know if it's available for our devices...
*Yes, most custom kernels have cwm built in, so you can enter even after factory reset or after formatting /system
*Overclocking depends on kernel as far as I know, but it's dangerous and your phone could brick (overheating, etc)

*it dosen't matter. Personally I flash the kernel prior to flashing the rom.
*Governor is basically a setting for managing the frequency of your processor depending on different values in different governors (try googling about different governors like- smartass,ondemand,lagfree etc). In my opinion you shouldn't go above 1.4 Ghz, you can go above this setting but your battery efficiency will drop and also you risk the chance of burning your processor. Your phone should be overclockable to that value but I have read somewhere that each chip is special to a phone.
I feel that 1.2 Ghz is a safe value for my phone and is fast enough for me. You can try it youself by downloading no frills cpu control from playstore and setting your desired frequencies.
