i have tried many roms but is it safe to use rom with overclocking ace ?? pls suggest roms without oc !! thanx in advance !!
"overclocking" and "safe" cannot be use in the same sentence. Its always been a risk of damaging hardware with overclocking. And it doesnt depend on rom, it depend on kernel. Most of the rom here doesnt include overclock kernel by default. But even if it does, u can just reflash with other kernel u like

I've been doing this whole "reading" thing about flashing and all that, but some confusion is still there.
I have rooted my newly got SGS2 (i9100, UK).
Now what ? I'm looking at Darky's rom, but there are two files to flash separately: kernel (darkcore1.7) and ROM itself.
1. I was just wondering what is kernel in this situation ? Can i keep my current kernel, which was flashed by superoneclick(2.1.1) or do i absolutely need to flash darkcore ?
2. Same question applies to any other rom out there - can i use different kernel to the rom i may want to flash ? A lot of them come in sets (rom+kernel)
3. Another question - if i mess up kernel flash somehow, does that kill "download mode" of the phone (voldn+pwr)?
I have SGS1 flashed just another day, due to it being "expendable" now that i have SGS2, so jumped in and flashed it following instructions, but without solid understanding. Either stuff gets too complicated or i'm getting too old for this **** (I do have a background of messing with PCs, videogame consoles (ps1 era to ps3/360), winmo6 phones, gadgetry in general...engineer at heart )
You can use any kernel with any ROM. And no I don't think your Download Mode will be gone if you mess up a Kernel.
Kernel don't come in sets. You can choose your favorite there. See Dev section for more details.
Regards.
Correction: SuperCore, not darkcore...
Can i use cwm app (v2.0)to flash any kernels ? Or does it have to be odin ?

Rom>>That depends upon the instructions as always in the rom you choose for a custom rom .
Kernel is flashed via Odin Via CWM app or via CWM recovery .
Kernel is the core of the system between hardware and operating .

Ok, so saying that, What stock Kernel can I use for Cyanogenmod7 ROM?
I was using "XWKE7" previously.
The ZIP file that i downloaded actually replaced my kernel with its own.
I'm asking this as I wanna use Tegrak overclock which is only compatible with stock kernels.

Stock kernels will not work with cyanogenmod. There are no overclockable kernels available for it yet.

After that you can flash back.

Hi,
I am from India, and using official stock rom v20c 2.3.3. I want to overclock my phone for playing lag free games. Can anyone suggest me how can I do.. what kernel i have to use so that I would not like to face battery drain, overheat, Problem with 3g or wifi, hotspot, tethering issues.
THE MOST IMPORTANT THING IS THAT before flashing custom kernel please tell me how to backup my official kernel.... so that if in case i will go back to the stock one.
Please share the link of custom kernel.
Is there any need to backup phone data such as apps, contacts ,messages, etc.?
one thing I also want to know that what kernel do.. what is its main role..?
Thanks in advance..

IMHO most stable kernel is paolo v5/v6, it overclocks quite good (with external app - e.g. No-frills), no problem with tethering (wifi or usb) or 3g. I think v5 has a little longer battery life.
To backup stock kernel you need to make nandroid backup (that creates backup of everything on your phone and in case of restoring, it will overwrite every change you made on phone since backup). To do that you need recovery (I'm using ClockworkMod Recovery, but there is also other recovery somewhere in our P500 thread).
Recovery is also needed to install new kernel. There is short guide how to do that in kernel thread (you need to install downloaded zip). New kernel doesn't wipe your msgs, contacts or apps if you made no mistakes.
Custom kernels do few things: fixes bugs made by lg, boost phone performance (different kernels give more or less boost), unlocks overclocking, changing governors (controls CPU clock transitions, and therefore battery life and smoothness) and scheduler (i have too little knowledge about android to say, what it should do, but i observed no difference between schedulers), gives you better battery life, fix touch lag (but not multitouch inversion lag bug).
You should try Paolo's and Franco's kernels and choose which one fits you better. Franco's need app to use wifi tethering but is faster than Paolo's.
I experienced more restarts on paolo's v6 and franco's than on v5 (my favourite so far, but there is also new paolo's based kernel that I haven't tested yet).
To install recovery (and kernel) you need root.
All needed instructions and links are here: http://forum.xda-developers.com/showthread.php?t=901247
AND MOST IMPORTANT THING - ALWAYS DO WHAT INSTRUCTIONS SAY AND DO NOT INSTALL KERNEL THAT IS NOT INTENDED FOR YOUR ROM, SO READ AND INSTALL CAREFULLY.

Hey Indian user, don't be afraid of flashing Kernel, you can always change it.. and I went twice to service centre with CWM 5.2.0... OC-480-729... franco's .35 kernel ... and they didn't came to know anything... but if you give them a phone with custom ROM then the'll reject it..
Abhinav i m a newbie to android.. actually i m an IT person.. n understands what u r saying but i m feeling afraid of doing any thing wrong bcoz i have already bricked my phn earlier while flashing gb through kdz.. so its very important for me to under the process first...
As per ur suggestion.. plz correct me or help me if i m wrong:
Firstly i have to download adb n install over my xp based pc..
Secondly in adb i have to run adb push command for sending the database file to the phn...
STOP..... WHAT file IS THAT DB IS...? N from where i get this.. i mean where did i get this stock recovery,? in which format is the recovry is?
And how the process will be run .. n how the clockwork recovery is replaced with stock one.. i have tried the combination of three buttons at startup in stock rom but no menu opens instead the phn will forcefully reset. so where is the official recovery?.
Help me plz expain how to do n for what to do in each n every step...
Is it true that after installing cw recovry n custom kernel we cant do a kdz stock flash..... Confirm me that after having custom kernel.. it should not lead the phone in non detecting position.. n if kdz works n can remove both kernel n cw recovery too then i think this is much easier ... i had seen a lot of post that o1 bricked by kdz flashing gb.... so if it possible then i have decided to flash froyo first n then update the phone via pc suite.... help me.... plzzz
Sent from my [email protected] OpTiMu$ On€ [email protected]
yes if u flashed a cutom kernel a custom recovery or a custom rom you can use kdz just turn on the usb debugging mode in setting>application>development to flash official stock froyo or official gb.. by using kdz method everything will be reverted back to stock recovery, kernel, rom, everything.. i suggest you to firstly flash the stock froyo using kdz method so you will be psychologically satisfied that you can go to stock

Hello there, and yes, i'm a noob
Tried custom roms and was never satisfied with them. Back to stock, and yet missing being a poweruser if you know what i mean! What are the recommended hacks/mods/tweaks that one can apply to takeover stock firmware? I have already rooted, tried changing dpi, playing with cpu governors, etc...but I want something reliable that can really improve the stock firmware. Like, is a kernel going to make it any better? Assumed that I do want to stick with stock (no pun intended) at least until CM9 (if ever).
Thank to you all and keep up the great job, everyone!
install lagfree v3 and turboboostv8.5
root your phone
download system app remover

Thank you for your reply. As i said, i already rooted. it's a good idea to remove useless apps, i'll totally do this.
And so you say lag free and turboboost can be helpful? Won't they break or mess the perfection of stock rom (irony)? it's not worth flashing a better kernel, maybe with more governors/schedulers or ext4 support?
they will just make your phone better
normally phone has 110mg ram when u do ram delete but when u flash this it goes to 80mg
phone is faster more free ram
maybe try to flash CF root
dunno what else you should do
I have never flashed a kernel before. Which kernel should i pick for safe use, battery life and ext4 compatibility on stock (GB XWKT7)? thx

So here's what i did. Wiped cache/dalvik cache, flashed b84. then wiped again and flashed turboboostv8.5, and then lagfreev3. Then i rebooted and in CWM Manager i flashed b84fix. Then i installed CF-Root-ext4-v1.3-Addon.apk found in Chainfire's thread, but when i launch this app it says that a CF-Root kernel was not detected and therefore ext4manager may not function properly. i ignored this and choose convert to ext4 option nonetheless. phone reboots into recovery, does something very fast and then goes back to normal functioning. seems like nothing happened. what should i do?
P.S: i have understood that i need to use another ext4manager on s5830. i am successfully converting to ext4 fs. thanks
Bcoz u have to install kernel via cwm app not install zip from recovery...
The b84 fixed is a kernel not to flash in recovery but in cwm app...u have option to install kernel there...

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)
If something is wrong, correct me

*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.
