4give me in advance .... I read the info in Dual Boot Support thread , but other than the ability to "dual boot" can U briefly explain what else this new version offers ... THX :)
[Epic 4G Android Development] Rodderik:
basically just fixed a typo in the cpu code and a new boot image...other than that and dual boot support it's the same as 1.1
[Epic 4G Android Development] TexasLTE:
Thank You Very Much For That Very Brief ( but helpful ) Explaination .... and THX for the updated "colonel" ;)
[Epic 4G Android Development] thomasskull666:
It's alive!!! x2 lol
[Epic 4G Android Development] kvan1707:
So we can install the new kernel, without the dual boot to just get the updates...?

sent from my Evo Killer with Genocide
[Epic 4G Android Development] Rodderik:
that is correct
[Epic 4G Android Development] JohnCorleone:
Waiting to get home to setup dual boot but 2.0 is smooth as a baby's bottom! Thanks Rodderik. Love the splash screen as well. Congrats! One last question because I only had time to skim the OP...when everything is setup properly, are you able to have both ROMs fully set up and switch between the two? Meaning can you have different apps on one setup than the other? Sorry for sounding noobish but this is exciting stuff!
[Epic 4G Android Development] XxLostSoulxX:
Hey rodderik is it possible to get the new 2.0 without a boot logo
[Epic 4G Android Development] TexasLTE:
Darn It !!! I downloaded 2.0 and flashed = now stuck in neverending bootloop !!!! HELP !!!! ........................................................................... nah , just messin' with ya ... LOL ! Nice Job ! :)
[Epic 4G Android Development] JohnCorleone:
The boot logo is clean looking! I think that's probably the last thing Rodderik wants to hear after all of the grief he got from the last one. I think it looks nice and professional
[Epic 4G Android Development] dchawk81:
Maybe I'm a nutter but the phone feels generally snappier on 2.0 compared to 1.1. Thumbs high Rod!
[Epic 4G Android Development] troyolson92:
I wiped my sdcard twice worth constant battery pulls trying to get voltages right. Also tasker cpu interfers and locks it up. If I could suggest, could someone make a version of this that is tweaked best it can to work on majority of phones and allow tasker to control speeds?
[Epic 4G Android Development] XxLostSoulxX:
i just like it without a bootlogo. it does look good i just like having no bootlogo is all
[Epic 4G Android Development] greatlakesghost:
I would have to agree with you. I dont do benchmarks so i cant prove this but it seems alot smoother to me, not that the other one wasn't mind you. Thank you rodderik, awesome work as usual! :-)
[Epic 4G Android Development] JohnCorleone:
I believe Rodderik did it so people aren't wondering if the flash took when they flash the kernel. This way you don't have to go into Voltage Control or SetCPU info section to verify which kernel you are using. Ok, on a side note, has anyone got the dual boot set up yet? I am about to get started but I am a bit intimidated...oh and yes the kernel is like butta baby...smooove!
[Epic 4G Android Development] Custodian:
Rodderik isn't sharing his under da hood tweaks I take it?
[Epic 4G Android Development] JohnCorleone:
Do you mean changes between 1.1 Final and 2.0 or Github?
[Epic 4G Android Development] Custodian:
Nah. Genocide will never be final. Rodderik just b spittin acid out his stomach when he says that.

And I'm talking about...his secret sauce.
[Epic 4G Android Development] JohnCorleone:
Oh, don't know if we'll ever know about that.
[Epic 4G Android Development] Custodian:
You know john, I think you're right aboot that.
[Epic 4G Android Development] CapsLockKey:
I don't know what's changed, but this is the first custom kernal that performs as good as stock with voodoo sound in terms of not crackling on my phone. Loving it. Haven't tried it with a custom rom, but I'm perfectly content running stock rom with this.
[Epic 4G Android Development] epic_image:
should i update to this version kernel even if I dont intend to use the dualboot?
[Epic 4G Android Development] JohnCorleone:
I did and its working really well.
[Epic 4G Android Development] Rodderik:
yes...as with most of my features like overclock, undervolt, and dual boot just because you have capability doesn't mean you HAVE to use them. the kernel is configured to run default as close as possible to a stock kernel as far as all that is concerned.
[Epic 4G Android Development] JohnCorleone:
Rodderik,two quick questions...what I/O scheduler do you personally use? Do you still recommend CFQ? And do you think a class 4 16Gig SD card is good enough to get this dual boot going or do I need to step it up?
[Epic 4G Android Development] Rodderik:
i still use the default of cfq but no-op sounds like it would be the best to use...and the stock is a class 2 16gb card and it is usable (just a little laggy) and my class 4 i tested with is a little better...so my suggestion would be to try it and see then determine if you should spend money on a faster card or not
[Epic 4G Android Development] JohnCorleone:
Thanks for the quick response and for another great kernel. I know dual boot was the big addition but this one feels extra fast and smooth. Congrats kernel Guru.
[Epic 4G Android Development] CapsLockKey:
I hate to be the bearer of bad news Rod, but the voodoo sound driver just got outdated already. Supercurio just dropped v10.
[Epic 4G Android Development] troyolson92:
damaged sdcard

I got this twice before on this kernel after 6-10 battery pulls setting voltages. I assumed i had this because of battery pulls. Now All i did was enable the 1200 and 1400 undervolt 1400 to be within limits. Everything ran fine all day and now I got a damaged sdcard again, all I did was shutdown to change batteries. It seems as if something is causing the damaged sdcard related to the kernel and voltages. Any ideas???

now it won't complete the shutdown, stuck on syndicateRom screen.
[Epic 4G Android Development] Rodderik:
where do you see this? i dont see v10 on github

thanks ill keep and eye out for him to update the epic source
[Epic 4G Android Development] JohnCorleone:
Rodderik would know better than me but this has happened twice in the past to me. The upper states can't be undervolted much at all. Some people can't touch undervolt above 1120. Have you by any chance been switching between Gingerbread and Froyo. I have been due to testing and my pics and wallpapers got wiped out. Just a thought.
[Epic 4G Android Development] tpike:
Fwiw, my quad went up 200 after running this kernel :-)
[Epic 4G Android Development] mouseglider:
Well, I need some help - I think I want to try my first kernel after reading everything I can about kernels and yes I have read this post over and over but can't find my answer - only because every ones setup is different and thus will have different answers - so if anyone has the time to answer my questions, I would appreicate it.

As my signature says, I am on a rooted stock EC05 rom with all patch fix's on my stock kernel and use cwm2.5.1.0 and my recovery works fantastic and has saved my butt a few times. I can't say one bad thing about my phone, everything works from BT to GPS etc, etc. I also am one that uses all the functions/features on my phone - maybe not all the time, but I do use them. I say this because I am not one who will say everthing works fine on this rom or kernel except BT, I don't use it so I don't care. I want "all" functions and features to work, period.

My quest is to stay as close to stock as possible because that seems to work for me. I am only looking for a little bump in speed with hopefully the same battery life. Yes, I ask asking something in gain and nothing in loss - probably impossible, but I was hoping the better coding and efficiency somewhere will all this to be close especiall since I just want a little bump, maybe 1120mhz or 1200mhz.

So here are my questions and I need specific answers please;

1) Can I upgrade my phone to this kernel and not lose any functionality to this phone.

2) I believe I do not have to wipe any cache for kernel upgrades so all my apps and settings will remain unchanged?

2a) OT, when roms says to wipe cache 3x's etc, does doing so mean you lose your settings and apps and have to reinstall? - just curious on this

3) Can I upgrade to this kernel from my current setup, i.e. from cwm2.5.1.0 or must I upgrade to a newer cwm first? After upgrading to this kernel will I have the new cmw and still have root? In th OP it seems I will have root and cwm3.1.0.1

4) If for some reason my phone doesn't like the upgrade, how do I revert back? I do have a progarm that saves my current kernel supposedly, it is called "SGS kernel flasher"

5) Will I lose my call log, camera sports mode, video lag fixs, and or will I have to reapply them after the kernel upgrade? Will I have to do the screen rotation fix again?

5a) Will I also lose my 1% battery mod which shows battery % left inside stock batter icon??

Other info if this helps, I just got updated to Voodoo Sound V10 today.

Or is this a waste of time for me and I should just wait for the official release of GB. As I would like to simply make this as simple and painless as possible as use my phone daily and don't really want to continually tweak to get it working from the stock Genocide kernel if not needed.

Thanks for putting up with this long read - and yes, I am somewhat of a chicksh!t when screwing with my only phone that is working perfect in everyway, unless I can image back to exactly what I had. Help, I am not a young wipper snapper like most if not all on this forum, I am just a confused old fart who likes his phone! :o :D
[Epic 4G Android Development] JohnCorleone:
I am on my Moto Finiti Bluetooth and this kernel right now. No issues here
[Epic 4G Android Development] tnynyn:
Just flash it through CWM, you dont need to reformat or anything, you wont lose anything. If you dont like it, flash to a different kernel. All info about the kernel is on the first post, including tweaks and etc...
[Epic 4G Android Development] mouseglider:
You are saying that I can simply "flash" with my current cwm2.5.1.0 and if I don't like it, I can flash my stock kernel back with my SGS kernel flasher?

Or upgrade my cwm2.5.1.0 to say cwm3.0.2.5, then make a nandroid, than flash Genocide, then if I don't like it since Genocide auto converts me to cwm3.0.1.0, I can flash back to my prior setup from the nandroid that I made with cwm3.0.2.5 with cwm3.0.1.0 and I will be right back to where I was, albeit with the only difference being that I will have the cwm3.0.1.0?
[Epic 4G Android Development] Mighty442:
Great work Rodderik, thanks for the updated kernel.
[Epic 4G Android Development] Rodderik:
yes

the kernel wipes cache and dalvik for you when you flash it but your apps are stored on /data so so apps and settings will remain intact

see above answer

upgrade to 3.1.0.1 so you can do a backup and it will save your kernel...2.5.1.0 will not save your kernel

before you flash the kernel do a backup in clockwork mod...then if anything happens you can restore that backup (which includes your previous kernel if you have cwm 3.1.0.1)

that is all rom related stuff...it should stay intact...see above answer

more rom stuff not kernel related...see above answer
[Epic 4G Android Development] mouseglider:
Thank you very much for answering my questions - I understand everything you said - just three last questions please.

1) How should I upgrade from my current cwm2.5.1.0 to cwm3.1.0.1? Should I upgrade in steps? Go from my current cwm2.5.1.0 to cwm3.0.2.5 to cwm3.1.0.1? Or just immediately jump to cwm3.1.0.1? and if I do upgrade in steps, do I reboot before I flash again, or simply flash the next cwm. I have read so many horror stories after flashing, that you tend to get stuck at the Samsung or some other screen.

2) Since I have the Voodoo Plus v10 from the market place and your kernel has v9, after I flash your kernel, will I or should I go and get v10?

3) Do I need to take my SD card out when flashing?

I also read somewhere that flashing a rom or a kernel, can't remember which, sometimes may get audio crackling sound that seems to be common when flashing rom? or kernel? Of course I am hoping that that bug is only when you are flashing roms. :confused:

Thanks Again!

Thanks again so much! :D
[Epic 4G Android Development] Rodderik:
http://drockstar.devphone.org/EpicTools/cwm3.1.0.1.purple.zip

just flash that to upgrade your recovery

no need to remove sdcard

as far as voodoo sound v10 you can try it after you flash the kernel....just as long as you make a backup in clockwork mod after you update it (before doing anything else) then anything you change can be undone by restoring that backup
[Epic 4G Android Development] CapsLockKey:
As an FYI for people, I've been loading the v10 module from the plus app and it's been working just fine with this kernal.

[Epic 4G Android Development] pixlz:
i've not experimented with dual booting... yet(bwahahah), but i think i love this 10x better than 1.1 just because the splash screen now looks like it belongs.

lovin it.
[Epic 4G Android Development] mouseglider:
As they say, one more question.:) I updated my cwm2.5.1.0 to cwm3.1.0.1 and everything seems to work ok I think. I made two backups but did not do any restores yet. I noticed that the new cwm3.1.0.1 adds/backups two more files android secure.img and recovery.img for a total of 7 files backed up instead of 5 like cwm2.5.1.0 - so I assumed that these are there because this new cwm backs up the kernel also.

Onward to my question; in your OP statement #7 and I just want to be clear, I can install your kernel on my rooted stock EC05 Odexed RFS system - as I think that is what you meant.

Excited to try your kernel - because of your answers it seems to me that kernel upgrades have less to do with BT, GPS probelms/issues, etc, because those functions are handle more by the rom?

Thanks again!
[Epic 4G Android Development] Rodderik:
if it is rfs you are fine
[Epic 4G Android Development] mouseglider:
Well, I just installed your kernel, no OC'ing yet, but I have a question again. Is it possible that when you boot up - I have read this many times before, but this is a slightly different request. That the blinking vertical ANDROID word is horizontal rather than vertical?

I ask that is because I can't remember what you have to do to get another ani boot logo, installing a rom or theme or something. With that being said, others who don't really care to do that "other mod" will have a more normal looking start up ani - maybe horizontal above the word Galaxy S :D

Other than that, I am just going thru and making sure everything is working correctly before I do any OC'ing - I did notice that I gain some internal memory storage thru your tighter more effecient coding - COOL!

Thanks!
[Epic 4G Android Development] hayzooos:
If you're getting a blinking "Android" logo on bootup, that's usually a result of a bad flash, unless that's the boot animation being used in whatever ROM you're using, and I doubt that's the case. I have a different boot animation, but I don't think you should be seeing that at all. I had that happen once, the first time I flashed a ROM on my phone. I reflashed it, and all was well.
[Epic 4G Android Development] mouseglider:
What happens is when I first boot up I get the normal Samsung screen and at the bottom it says something like "Kernel brought to by Rodderik" - then when it goes into the standard Samsung yellow checkboard ani I see the word ANDROID sideways/vertical and it blinks while the stnadard Samsung checker board think is still doing its thing (it's like is an overlay thing) - it continues to blink until I see the BIG S - it still there but it stops blinking after the second BIG S appears and then finishes to the final stages of its boot up as normal. With tah being said - it seems to boot normally and in approximately the same amount of time.

I just tested all my apps, and multimedia apps music player etc. I also tested all my benchmarks apps and basically my phone works as it did before - i.e. perfect - I am on a Stock Odexed EC05 rom with a non OC'd Genocide v2.0 kernel. So now you have me somewhat concerned - not that it is difficult to reflash the kernel. I thought when you got the blinking sideways Android word it was simply there to show that it can use custom bootup screens.

I mean I suppose I can reflash and do all of my tests again - but if it is normal than I can start playing with OC'ing - what do you think?
[Epic 4G Android Development] Rodderik:
not true on stock rom...it is the default boot logo from the kernel playing on top of samsung's proprietary qmg boot logo...this is normal behavior on a stock rom

ill update shortly with what to do about it
[Epic 4G Android Development] mouseglider:
FYI for anyone else that has previously bought the Voodoo Plus app from the market place. Even though the OP says it has an updated v9 of Voodoo Sound in the latest Genocide v2.0 kernel, after I flashed the kernel, my Voodoo sound driver stayed at v10.

So the flash didn't downgrade my Voodoo v10 to v9. I thought I would have had to redownload and upgrade it back to v10 - but everything stayed the same and all works fine.
[Epic 4G Android Development] mouseglider:
Thanks for the quick response, I was hoping I wouldn't have to reflash and retest - - simply changing the Android word to a horizontal version is all you would need to do if that is simple - then I doubt any noob like me probably would never ask that stupid question :D
[Epic 4G Android Development] omair2005:
Hey I have a issue. Under voltage control I have set min and max at 200/1300 but under cpuspy it says 1120,1200,1300 are unused??
[Epic 4G Android Development] hayzooos:
Got it, good to know, and thanks for correcting me.
[Epic 4G Android Development] JohnCorleone:
Hey Rodderik, has anyone reported back that they got dual boot set up yet? With all of the testing I am doing, I want this soo bad but its a little over my head. I have to wait for the app you are putting together...or do some studying.
[Epic 4G Android Development] Rodderik:
first off you are using VC i have in the OP and not an updated version right? did you set the states enabled in VC and hit menu>apply now? and then did you select 1300 on the main screen and hit menu>apply now?

btw my name is spelled wrong in your signature....there is no c :P
[Epic 4G Android Development] Rodderik:
for the boot image deal check out this post by nubecoder http://xdaforums.com/showthread.php?t=951184

it will get rid of the flashing android if you have the stock animation...he also provided a way to remove the stock animation if you want to use a custom one....this seems to work wonderfully for our problem
[Epic 4G Android Development] Rodderik:
added the boot animation stuff to the FAQ in the OP
[Epic 4G Android Development] Rodderik:
no one has confirmed it but i'm sure some people have....the app should be out later today i hope...it's almost done
[Epic 4G Android Development] MysteryEmotionz:
Roderick just a work of advice. I seen you wanted to do a 1.3ghz kernel. Not every phone can handle that so if you do you might wanna make 1.0ghz and let the user scale up. I would leave the 1.2ghz step in. I flashed a 1.3ghz alpha build last night. My phone locked up like it did in eclair causing me to battery pull. I flashed your kernel back and when booted I was greeted with fc. I know the fc was due to the no journaling on ext4. I had to re flash everything over again
[Epic 4G Android Development] mattallica76:
That's a very good point. We are gonna have to be careful with OC kernels and no journaling.
[Epic 4G Android Development] blspyro:
I have flashed several kernels between today and yesterday the one time I thought I had ext4 properly function I still had dk28 showing up in my phone info as well as eb13....hopefully a eb13 ext4 kernel will be released soon.
[Epic 4G Android Development] musclehead84:
How do we disable journaling on eb13? Is there a no journal mod to.flash yet? Thanks

[Epic 4G Android Development] Rodderik:

10char
[Epic 4G Android Development] Rodderik:
thx for the advice...im plan is make it default to 1.0 when i add the 1.3 step in

can you elaborate a little about the FC being caused by no journaling?

in my initramfs here are my ext4 mount points (if they fail it drops to the next line mounting as rfs)

mount ext4 /dev/block/stl11 /cache nosuid nodev noatime nodiratime errors=continue nobh data=writeback barrier=0 noauto_da_alloc
mount ext4 /dev/block/stl9 /system noatime nodiratime errors=continue nobh data=writeback barrier=0 noauto_da_alloc
mount ext4 /dev/block/stl10 /data nosuid nodev noatime nodiratime errors=continue nobh data=writeback barrier=0 noauto_da_alloc

i do not removed the journaling. do you have it removing it in a cwm script or something for a rom? i'm a little confused about your FC issues. thanks
[Epic 4G Android Development] endurance1:
my words exactly. however.... what exactly is the "minimum" for in setcpu? what happens if i just put it at 1200 minimum and 1200 max?
[Epic 4G Android Development] MysteryEmotionz:
The fc was due to data corruption from pulling the battery.

When I flashed the 1.3ghz kernel 1.3 was set at default. After the media scanner stopped my phone locked up completely (this happened to me on eclair). I had no choice in the matter to pull the battery. knowing 1.3ghz won't work for me I flashed your kernel knowing 1.2 works. I was greeted with all the google apps fc and the google framework. This happened because my phone didn't power down proberly and the data was never writting due to journaling being disabled
[Epic 4G Android Development] Rodderik:
ok so you had journaling disabled on the 1.3 kernel you were messing around with before you flashed my kernel correct? just making sure it wasn't something i did. for now i intend to leave journaling enabled because in my experience removing it help benchmarks and actually (back on dk28) made the phone run like crap. thanks again for the advice.
[Epic 4G Android Development] Rodderik:
i would set 100mhz as the minimum unless you run into any issues with the phone not waking up then try it at 200mhz

if you set 1200 as min and max then it will stay clocked at 1.2ghz and not scaled down...when it scales down it uses far less voltage than the 1.2ghz step so unless you are benchmarking i do not recommend setting 1200 as min and max
[Epic 4G Android Development] endurance1:
ok thank you. let the roms come! im ready!
[Epic 4G Android Development] qbking77:
Will Roms most likely have this incorporated into it when you flash the rom? Or will you have to flash this kernal separately?
[Epic 4G Android Development] endurance1:
im not the person to ask this, i barely know what im doing, However i do think you would have to flash this if you install a rom unless it is already flashed. this is if you want this kernal, which i do.
[Epic 4G Android Development] Rodderik:
it is up to the rom developers if they want to include the kernel in their rom. i'm sure we will be putting the kernel into viper rom builds. all the other rom devs are welcome to include my kernel into their rom builds if they want.
