[Q] [kernel] noob help!!

hey? so there is much buzz about fugumod kernel blah blah
so as a noob representing the noob g3 users community [i hope there are some other than me]
my questions:
q1,differnece b/w rom and kernel??
q2,how to use one??
q3,if it overclocks then does it drain battery too fast??
q4,are they stable and safe to use??

Hey.
I bought my first Android phone 5 days ago, so I'm a noob too
But I'm a Linux power user.
Kernel is the core of the operating system, it contains drivers, filesystem interfaces and APIs needed by computer hardware to function. Android basixally uses Linux kernel.
ROM is short for read only memory, this is where the kernel and user interface (the pretty menus, homescreens, icons etc.) are installed. The propper name for this would be OS, but on phones people call in ROM, because of the place where it is installed.
Higher clock speeds require more power, more power drains the battery faster.
I havw not tried Fugumod kernels personally, although I am tempted to. It should be safe, but the only way to know that is trough extensive testing. The normal one seems safe, but no OC there.
These are simplified explanations for noobs, there is much more to it, but for gods sake, Im typing this on a 3.2 inch screen!

Pretty much the required anwser, but also dont forget this:
There is still bugs and problems with the OC version of fugumod kernel,cuz its stiil being ported to our phones.
Also only overclocking does not help for performance boost, We need to put JIT and COMPACHE, making more difficult to install if you don't know what are you doing.
Also, according to some user that tested OC, some phones cant be overclocked to 1.3 ghz or less making the task pretty risky...
The best we can do is wait until a custom rom adds this kernel to prove this.

So if a custom rom comes with a kernel,i guess it would be easier as flashing a is easy.am i right?or the process would change

i have a few noob questions too
-to install fugumod 2.2, do I just flash it on top of my kyrillos 3.0?
-what is a fs.convert file and how do I make one?
-and lastly, what is ext4? How does it make it any faster?

There is a topic on fugumod. Not the right place to ask but here it is.
-Yes.If everything goes fine no data will be lost.
-It is a plain text file made with Root Explorer or any similar app. Just rename it to fs.convert
-ext4 is a Linux filesystem, just like FAT or NTFS in windows. It is faster than rfs.

[Q] Motorola Defy Kernels

hi guys, I would like to ask experienced users what is the difference between the kernels we used on our Defy(s)
Froyo Kernel vs Gingerbread kernel vs Walter79's Kernel
I first encountered this kernel upon viewing the CM9 update thread
I have a red lense defy and the very first rom I flashed was the official CM7.1 so I am aware I do have a Froyo Kernel running on this bad boy.
what is the difference/ advantages?
which is better?
is it safe to flash one over the other?
is it easy to flash? like how we flash roms? we can always go back to to Froyo kernel from the gingerbread or walter kernel and vice versa?
I think a lot of noobs would appreciate your answers.
I will edit this post and add your answers so that others may find it useful as well
some answers--------------------------------------------

Ans:My experience says that the main advantage of using GB kernel is battery life..
Defy-4.5.3-109_DPP-11-kernel is well known for awesome battery life.
which is better?
Ans: I personally think Walter79's kernel is better in every sense.Unfortunately for old defy owners(SOC camera green lens), camera wont work on new kernels without any extra fix..
is it safe to flash one over the other?
Ans: Yea its 100% safe..i personally never had any problem as such..but i heard few people faced bootloop..in any case you can always go back to froyo or watever kernel u were using
is it easy to flash? like how we flash roms? we can always go back to to Froyo kernel from the gingerbread or walter kernel and vice versa?
Ans: As i have already mentioned above, we can always switch between these kernels..just remember not to flash any GB kernel based sbf or else u will be stuck! before flashing any unknown or less known kernel PLEASE USE THE SEARCH option and know more about the kernel and related problems.

Thanks for this information bro!!
Please also share Camera fix (link) for GB kernel for SOC Camera and also mentioned whether downgrade is possible. Your help will be appreciated.

anyone correct me but we can do dual boot but can't install dual kernels?
say
cm7 (froyo kernel ) as system
cm9 (gingerbread kernel) on SD
and will Gingerbread kernel work with cm7 for the defy, red lense?

No, can't do it. Both ROM's should share the same kernel.

thanks Auris, would you be able to add anything or negate anything that was previously posted about the Defy Kernels?

Please help me a bit with those kernels! I have a defy+ with 2.3.6 base and one of those newest official build nandroids. Can I flash Walter's kernel? ^^
Just don't want any bootloader error!

Is it okay to flash defy+ rom zip and then the gb kernel on a green lens defy? To me battery life is more important than camera

Defy kernel Flash
i have a motorola defy green lens currently running cm9 4.0.4 (camera's not working but i don't care much for the camera ) . ok here's my problem i'm trying to flash a different kernel on my defy.. the current kernel im running is 2.6.32.9 cdt 2011 but i need better performance and i tried to flash semaphore kernel. the flash was successful but i see no changes and also in the settings>about phone the kernel version hasnt changed. i need help so that i can flash new kernel properly.. thanks

Hi!
I realize this is a very old thread, but it seems to be one of the few addressing the (dis)advantages of the froyo vs the GB kernel (independently of the ROM!).
The 720p-recording is really not important to me, but battery life is and I just read here that it would be better on GB kernel.
Do any of you have further experience with regards to battery-life difference between Froyo and GB kernels (not ROMs)!? Is it a big difference (to what extent or through which features?)
I have a MB525 with red lens and Froyo kernel, so I could go for a GB-kernel.
I've recently rooted my smartphone and flashed WIUI (3.1.27, GB&MIUI-based) on it, because (1) my phone was slowing down, (2) I wanted not to have any bloatware anymore and (3) I wanted some apps that only run on Gingerbread/2.3+ (e.g. the offline-language-package-feature from Google Translate). Almost everything is now better.
BUT, my battery life got worse! I've now down-volted my smartphone to a stable point and set it to 'smartassv2', but am looking for further improvement for the battery life. As WIUI can be installed both on froyo and GB-kernel, I might also update the Kernel...but only want to take the plunge if it really would make a difference...
any advice or experience is welcome!

Help Kuro Kernel

Hi to all, i need a little help with the installation of this kernel. I'm trying to install it in ussr v3 and v4 and always get bootloop. I read that is necessary to uninstall a2sd but i don't know if those ROMs have it (both have Repencis kernel) and i don't know how to uninstall it. I checked init.d folder and i dont see any files with "a2sd" and i dont have my sd-card partitioned or anythig so i dont know what to do, please help. Thanks in advance guys.
pd: Sorry for bad english.

I to had the same problem but i was able to install the kuro kernel but i was using ICS fusion v2.0 rom
unroot ur phone
do a data wipe/cache
before installing kuro kernell
After installing Kuro kernel u may root ur phone again.
And remember always to flash it via CWM & not the stock recovery
u can use the faqbly method to flash the kernel
http://forum.xda-developers.com/showthread.php?t=1552889

what? unroot? I don't know why did my kernel got a problem with root stuff. try this one. usr have bacem tweak inside it, you'd better remove it or change the value to -20mV before you install my kernel.

i install this kernel with Repencis v3.5 and i didnt get bootloop maybe the a2sd thing is the one thats get you a bootloop cause i use link2sd..because of that i didnt got any problem
btw this kernel is COOL really fast and battery saver

Hi noob question here
I flashed kuro kernel(love this kernel BTW)on samsumsung kies updated stockrom but IMEI number disappeared (IMEI blank)gone from phone has anyone else had this happen. Is there a simple fix to this or reason ?, or do I have to stick with xxla2 which is fine but I love the enhancements on the kies updated rom
I have flashed back stock xxla2 and IMEI number has returned so no damage done
I did'nt note down the kies update number my bad.
edit
service version : PDA:LK3 / PHONE:LK3 / CSC:LL1 (XEU)
Thanks
kernel 2.6.35.7
android version 2.3.6
Gingerbread xxla2
Kernel version
2.635.7

same problem
cannot installed this kernel on purekat rom.i get installed aborted.why?

You really need kuro? Try savie SGY kernel.. It optimizes batter life and it has 15governors!!

is savie better ? what is the difference ?

please refrain from saying one thing is better than something else as this is normally not true in the scientific sense or just personal opinion
your use can differ from someones else so what might work "best" for you may not work "best" for someone else

[Q] repencis rom 3.5 for galaxy y

hey guys i am using repencis rom 3.5 on my galaxy y........its amazing nd stuff but wen i used to use my stock rom i had overclocked my phone and also increased internal memory space using link2sd.....these two things i'm not able to do on this repencis rom 3.5 as the phone hangs during process when i follow the standard procedure for overclock nd increase memory space...plssssss help i'm confused

Hey....guys i installed repencis rom 3.5 for galaxy y......it's kinda great.....but one problem....i dunno how to overclock my phone on this new custom rom.....i tried the same overclock procedure that i tried wen i had my stock rom but the phone did not start up on this new rom during boot process...please help urgent??????

I am very sorry to inform you that Repensis Kernel doesn't support overclocking. If you want an overclock kernel, try Merruk Technology Kernel V2.5. Else, flash Savie's Kernel and overclock it the way you did so. Merruk kernel v2.5 is already overclock to 1.2 GHz. You don't need to flash overclock zip again. But Savie kernel is not yet overclock. You need to flash the overclock zip file to overclock it to 900MHz. Only Stock kernel, merruk kernel and savie kernel supports overclocking till date of all the available kernels for Galaxy Y. Always keep in mind that overclocking drains the battery and heats up the phone which can cause damage to your handset. Just reflash Repensis Rom v3.5 via Clockwork Mode Recovery or via Stock Recovery. As to Link2sd, first partition you sdcard as primary in ext2 format. When link2sd ask you to choose the format, select ext4(very important) and then reboot you phone.
Hit thanks if I helped you.

[Q] Repencis kernel broken?!?

Hello Mr. Repencis, and congratulations for your work.
I used Repencis V3 pro rom for more than a year, and i was always satisfied. I chose it because it was the one that took up less ram than any other I've tried and also because it had amazing graphics and cool features (eg a2sd support).
I recently installed version 3.5 found on another website, because here all the links are broken and I was surprised by the amazing graphics and low memory usage.
The new kernel also supports scaling of the CPU, but is not really complete regarding available frequencies and governor.
So i'd like to install kernel 7 final or at least 6.3 because most complete functions and scaling governor available, but absolutely does not want to work.
I tried to install it on your rom and also in other roms (jellyblast and hyperion) but i had no success (bootloop or locked at samsung screen).
However I successfully tested kernel USSR (also supports a2sd) and also Savie kernel (fabulous for the cpu, but no a2sd support). Both works in repencis 3.5 rom and on Hyperion 8.
Now.. Can you give me a hand on how to install your kernel and, above all, can you give me a link that is safe? Your kernel has the perfect features that I want, but it seems i was completely unable to make it working.
I also tried the version 6.3 of the kernel without success.
I came to see the boot image and then reboot loop.
Thanks and goodbye.

Yes it is

Repencis hasn't been round here since about half way through last year
Try hells fusion #50 - its the latest stable kernel around here

Thank you
This day i have installed merruk kernel, but it seems i have some problems because my phone shutdown.
Now i want to correct max frequancies but supersu doesn't work anymore. It seems a well known problem with merruk kernel.
I installed superuser and removed supersu and it seems ok!
I was interested in repencis kernel because i like to use as2d and i have only found Repencis and ussr kernel support a2sd.
But then i understood that a2sd have a problem preventing deep sleep mode. So maybe i need to convinc myself to use link2sd.
P.S. What do you think about savie kernel? Don't you think is better than hells?
PPS where can i find latest hells kernel?
Really really thanks and goodbye!

Both Davies and hells are quite complete and stable. Hells kernel can be found in the galaxy y's android development section. A search wouldn't harm I guess
