I don't know how, but this kernel has actually made my Epic pleasurable to use again.

My phone in a nutshell,

Was running rooted DI18 and life was good.

Then EC05 hosed my battery life. I couldn't get more than several hours per charge while idling.

Went with SFR1.1.0/Twilight1.1.0/EB13 modem and got reasonable battery life back.

But not still not what it was with DI18.

Went with SFR1.1.0/Genocide1.1/EB13 modem and suddenly jumped to having better battery life than I've ever had.

Now using SFR1.2/Genocide1.1/EF10 modem and I'm finally getting the amazing battery life that many people have claiming for months, but has eluded me ever since ECO5 was released.
[Epic 4G Android Development] mjben:
Thanks for the clarification. I had read that the ondemand governor had been fixed (at least so it didn't drop below the min), and that people were using it. So I gave it a shot.

Been on the kernel for about an hour, using my phone non-stop, UV'd about 1/2 hour ago, and have only dropped about 6 percentage points on battery! HOLY BAT GUANO! Thanks Rod!

I tried your settings and I would get a lock up a couple minutes later. I added 25 to each one and everything seems to be stable for me. Going to test it for 24 hours.
[Epic 4G Android Development] chuhsi:
super beginner question: what should my kernel version say w/ v1.1? My phone currently says 2.6.32.9.

When I first installed this kernel with EC05, I swear i thought my kernal version said something like genocide 1.1.

But last night, after odining EF02 and OTAing to EF10, I got a bunch of FC's. I reverted to a backup with SRF 1.1, upgraded to 1.2, then reflashed genocide 1.1. Now my kernel says 2.6.32.9, even after a few kernel reflashes.

Did I do something wrong?
[Epic 4G Android Development] Shoulon:
Use CPUspy from market, its free. that will tell you the kernel you currently have.

and what Rodderik said. it's impossible to miss that flashy as flip font lol. (below this post)
[Epic 4G Android Development] Rodderik:
also if you flashed the 1.1 final you can tell when you first turn the phone on
[Epic 4G Android Development] greatlakesghost:
Lmao, love the splash screen btw.
[Epic 4G Android Development] chuhsi:
I definitely see the wild genocide flash screen before the ACS flash screen. I guess I'm good.

[Epic 4G Android Development] Rodderik:
firmware in about phone can be changed with the default.prop https://github.com/Rodderik/Genocide-Kernel/blob/master/EC05_Genocide_initramfs/default.prop#L8

but this has caused a few apps to mess up which is why i don't do it

you can also append extra info to the kernel version itself https://github.com/Rodderik/Genocide-Kernel/blob/master/build_kernel.sh#L38

I've finally settled on -75mV across the board. No lockups for a couple of days now.
[Epic 4G Android Development] Xhyperion:
Can you list it please.
[Epic 4G Android Development] Shoulon:
it doesn't matter. Just because he can use -75mV, doesn't mean you can. (that sounded so mean =/ )

As for me. Best I can get was

1120mhz @ 1175mV

1000mhz @ 1150mV

800mhz @ 1100mV

600mhz @ 1100mV

400mhz @ 1000mV

the 200 and 100 could not be changed.

Is this on conservative? When did you get your epic? How long have you been running that uv?
[Epic 4G Android Development] XxLostSoulxX:
Yes i'm on conservative, i had to get a replacement because mine was stolen so like Begin of this month like 6/8-6/10. Been running for atleast 45mins or so. Its been on standby havent done anything i got on market looked around on internet. its fine to me. is Undervolting that far bad or something or is it fine? im curious. but i notice on SetCpu it shows it hitting 100Mhz and not freezing up at all
[Epic 4G Android Development] Xhyperion:
Mine is similar to yours except the 100 and 200 step. I just uv the 400 step to yours. I'll see how that runs tonight. I just tried your 200 and 100 step but it crashed. I'm on 900 for 100 and 200 step for now. I'll mess with them tomorrow but I can't get your uv. Lucky mofo. You must have minimal drain on standby.
[Epic 4G Android Development] XxLostSoulxX:
in a way i'm happy they stole my phone haha

Your 400Mhz is @ what mV?

lets see if i can get 100Mhz down another 25mV?

Yep LOL

ill see how long i can go with it on to make sure if its completely stable

EDIT: its been like 30 mins and its fine NOW -275mV in attachments

Just got it down to -300mV so 100Mhz@650mV

Hi Rodderik,

I come in peace. (offer marshmellows)

I did everything you said, including doing backup, etc. Everything is working and faster. Real nice and great job on it. :-)

Now, do I need to alter any settings? Or are all these optimized the best way possible by you? And I see Voodoo Sounds, do I have to keep it or delete it? Anything that is not important to me (deaf) okay to delete such as what extra goodies?
[Epic 4G Android Development] Rodderik:
voodoo sound is baked into the kernel and you can't delete it...there is an app to control it's settings but i wouldn't worry about downloading that :)

basically if you don't want to overclock or undervolt then you don't really need to do anything special...overclock = more performance at the cost of eating more battery, undervolt = bringing down the voltage for each clock speed in hopes of squeezing out more battery life

i like options so it's up to you!
[Epic 4G Android Development] ThunderOKC:
Kool. I trust you with my phone. I trust you with my life. I trust you with my cat. :-)
[Epic 4G Android Development] Rodderik:

J/k but the cat skull thing was a huge as the resturant was pretty popular whoa that was almost 20 years ago if not more, I'm getting old :p

that's crazy...but for some reason i'm not suprised
[Epic 4G Android Development] jirafabo:
Just flashed this kernel to try out some of the undervolting. I also added an elixir widget to monitor what my cpu was doing with the new kernel. I'm getting an immediate FC when I open my phone app.

I tried clearing data in com.android.phoneinfo and I removed the widget and rebooted and still getting the phone FC. any ideas?

seems to be the only thing FC'ing.
[Epic 4G Android Development] kvan1707:
I had a similar problem, I wiped everything and reflashed the 1.2 and genocide 1.1 final and restored my apps. I had to do this twice, but now it works without any FC's.
[Epic 4G Android Development] hayzooos:
I would think the Dialer.apk (I think that's what it's called) would be the issue, not the phoneinfo part. I could be wrong though, just a thought.
[Epic 4G Android Development] jirafabo:
I found the problem. I'd like to apologize to the Genocide creators, as the phone FC issue is related to the 6/8 lockscreen mod and SRF/ciq removal. There is an easy fix, but it is post 101 in that thread, and for some reason, never posted to the OP. Lame!

Stuck on Samsung startup screen

I read through all the posts since 6/15 and haven't seen anyone post this issue... wondering if anyone had insights?

i was running srf1.1.1 with genocide1.0...

did a backup, and wiped cache/dalvik x3 and flashed genocide1.1final. then when i rebooted it stayed on the samsung startup screen for too long... kind of reminds me of when i tried to flash cwm3.0.2.5

so i pulled battery, and 3fingered into cwm. noticed it was still orange (3.0.0.6) -- restored my nandroid, rebooted... and i'm still getting stuck on the samsung startup screen.

i hate think this but i'll probably have to Odin back to stock and build my way back up to srf1.1.1 and then restore..

any ideas what went wrong? i really want to try on this kernel but i don't want to go through that whole cycle again!
[Epic 4G Android Development] cache83:
alright... i'm back. just recovered from a full brick -- what a day. got myself back to srf1.1.1 and i think i just successful flashed genocide1.1final.. when i 3finger salute tho i still get cwm3.0.0.6...

i read a couple of pages back that i might have two diff cwm's on different partitions, i know someone mentioned they still had 3.0.2.5 going after flashing this kernel

my only question is: is that ok??! or does that mean that i have an incomplete flash of some sort?
[Epic 4G Android Development] Rodderik:
glad you got it back working...

[Epic 4G Android Development] omair2005:
i'm having a weird issue. I"m on SFR 1.2, and I checked cpuspy and it said deep sleep was used but when I rebooted my phone it was an unused state? I've tried rebooting several times now and its still unused.. any help
[Epic 4G Android Development] Rodderik:
unplug the phone and leave the screen off for about 10 minutes and you will see deep sleep pop back up on it's own
[Epic 4G Android Development] omair2005:
thanks will try this out

*update* that worked! thanks Rodderik
[Epic 4G Android Development] jhormaze:
How do you know when the kernel is installed if it doesnt show up in ABOUT PHONE
[Epic 4G Android Development] Rodderik:
when you boot the phone you should see a splash screen before the boot animation
[Epic 4G Android Development] jhormaze:
mine only shows the ACS boot animation and ive installed the genocide kernel twice :( Any ideas?
[Epic 4G Android Development] Rodderik:
when you reboot the phone you should see

BEFORE the ACS boot animation...if you only see the samsung splash then redownload and try to flash again
[Epic 4G Android Development] jhormaze:
Ok thank you :) i think i was installing the wrong thing ! I really appreciate it :)
[Epic 4G Android Development] hayzooos:
I know Rodderik already answered this, but the phone doesn't deep sleep when being charged. Mine seems to run at 200mhz (the min I have set) while it's charging and that makes sense. When it's unplugged, however, deep sleep is used whenever the screen is off.

If your deep sleep doesn't show being used, then you have another issue going on as something isn't allowing the phone to sleep and your battery will probably drain quite quickly.

Gallery was one culprit of this. If this happens, use Spare Parts under partial wake usage and that should tell you what's keeping your phone awake.
[Epic 4G Android Development] thomasskull666:
EDIT: statement retracted :-)
[Epic 4G Android Development] garyf:
Is there an option for either a more low-key kernel splash screen or to omit the splash screen entirely?

Is can a different version of the kernel be uploaded for those who haven't had problems changing kernels.
[Epic 4G Android Development] hayzooos:
Well that's a bummer...I know you make kernels so I'm now curious as to what you posted!
[Epic 4G Android Development] thomasskull666:
Lolz, just a goof on my part. I thought the person I was quoting was asking if deep sleep is used during charging, but he was making a statement
[Epic 4G Android Development] gitit20:
Hi thank you for this it works well with i am using this now with ACS Frozen 1.2

I was wondering if you can give me more detail on what is causing the unsuitability with SetCPU I am using SetCPU with 0 issues i also tried voltage control and still works the same i notice no difference Just curious...

I know your busy but when you get some time please let me know :) i am hungry for info...
[Epic 4G Android Development] Rodderik:
the new version of setcpu i believe allows you to undervolt and everything...before it wasn't like that so unless you were doing voltage control's job manually via command line the two apps don't play nice together and causes some instabilities...i haven't used the new setcpu with the undervolt stuff so i can't say for certain. but i am sure some other users can chime in on the subject and teach you and i both something.
[Epic 4G Android Development] thomasskull666:
When the whole undervolting thing came about, Voltage Control was the only app the could be used to change voltages, thus meaning SetCPU became irrelevant. It was advised not to use both simultaneously as they conflicted and then caused issues together. Now that SetCPU supports undervolting, I guess it is necessary to say that you can use either one just not both.
[Epic 4G Android Development] thomasskull666:
Lmao what are the odds we would both respond at the same time, at like 3am lol :-)

Grab Set CPU from the market and see if you can set the cpu speed to 1.2 ghz. If you can you have it if not you dont. It is in the OP.

Pure EB13 kernel running great :) Ext4 and everything, on the stock de-odexed ROM. Smooth as silk. great work Rodderik.

Still lapping boot animations. Maybe it will be fixed with a custom ROM later on.
[Epic 4G Android Development] v3rk:
this should be flashable over the stock dualfs kernal, am i correct?

edit: forgot to mention, on ext4 with cm3. and if so, any wiping necessary?
[Epic 4G Android Development] brickwall99:
I could be wrong but I think 0.2a is faster, based on benchmarks. I'm still running Viper 4.03 on EXT4. Got 1883 in Quad and 16.7 on Linpack. It was faster in Smartbench 2010 also, forgot the scores though.

Nice work!

on EB13 -ext4 but when i run the kernel after it installs get stuck on a boot loop. screen goes black for a while, samsung logo comes up then goes black again and so on. any ideas? did a clean wipe before and after addin custom kernel and no dice.

WOW that was a fast answer lol thanks guys I understand why you would not want to use setcpu before but to tell you the truth i dont do anything with my under volting i am going to try doing some to get better battery life i bought a used samsung epic with a bad esn that i test everything on before i put it over to the good one so i will play with this some its handy because most the time i just do a clock work back up and then restore it on the good phone :)

Also was wondering of there is some way i can change the splash screen back to samsung?

Thanks
[Epic 4G Android Development] Rodderik:
ill answer this since you aren't the first person to ask....if you want to change the splash image you will have to download the source from github and compile the kernel. in the source is a backup of the original logo file and on github there is a script to convert a custom logo. compiling a kernel is not hard and if some one wants to compile one with out the logo and post it in the thread that is fine. i personally am not going to maintain multiple versions because i've worked too hard so i didn't have to. my personal opinion is it's a splash screen and the typical user shouldn't have to reboot their phone a million times a day. if i'm not dev'ing stuff then i don't reboot at all usually. i guess i just don't see why a logo is a big deal. and just a little fyi for the curious, the original idea behind pursuing the ability to use a logo was mainly because so many people kept asking "how do i know if the kernel flashed?" and that is the most simple way that doesn't cause any issues with pinch to zoom in opera and other weird off the wall behavior or take away from rom developers branding their roms in about phone. so there is my long winded explanation of the whole deal that isn't directly addressed to you gitit20 but so that everyone that has asked or thought that same question understands. and on that note since it's 4 am it's time i sleep.
[Epic 4G Android Development] gitit20:
ok i understand :) after reading that i do think i will leave it on not because of the compiling but to show my support :)
[Epic 4G Android Development] Xhyperion:
I like the splash screen. I reboot alot to free up memory when doing intensive stuff.
[Epic 4G Android Development] Krazy_P@:
Dude I'll compile a new kernel with a lower key boot screen, what's wanted? Peronaly I think the 2 seconds it's up is no biggie and I like it but I just about finished getting my development enviroment set up and wanna test it out, anyone know what they want?

And Rodd what should be included, props 2 u 4sure, gotta say Genocide 1.1 I assume and devphone.org, anything I'm missing? Or restrictions you got on it?

Edit: saw the SetCPU Q's, 2.21 works great but no way to change the I/O scheduler that I've found yet... only had it on my phone for a few hours tho so yeah not much time w/ it...
[Epic 4G Android Development] garyf:
I think just the stock samsung boot image, plus some white text with an indication that the kernel is now booting and all the required text would be great.

Something super simple.
[Epic 4G Android Development] vickpick:
w/ max voltage at 1.3 GHz, I get a quadrant score of about 2200. Awesome!
[Epic 4G Android Development] cache83:
i'd like to agree w garyf -- something simple like the stock samsung boot image that in similar white text says Genocide Kernal 1.1 final, giving props to Rodderik
[Epic 4G Android Development] fami:
I personally liked it when the kernel didn't have an independent flash screen at all. The enormous ASCII banner proclaiming that you're flashing Genocide 1.1 in CWM was more than enough assurance. Android follows the fundamental UNIX approach of "no news is good news", and there's a lot to be said for that tack.

That said, the only real objection I have to the splash screen is that the word GENOCIDE blares across my gorgeous screen in a very obsequious way. I'm at work 11 hours a day, in a very culturally diverse environment, and when I reboot that two or three times a week I get very self conscious about this otherwise minor gripe.
[Epic 4G Android Development] mjben:
On a similar note... my mother took in an eyefull of Genocide after watching me change my battery. She never said a word. It was kinda funny, and kinda odd.

Personally I would prefer something more low-key. Even the ACS and the stock Sprint splash screens are too much for me. These all seem ...well, childish. We're not all teenagers who use these devices.

I use a BIOS boot animation and old phone ring tones myself. Stock sprint ringtones are the absolute worst thing I have ever experienced on a phone, sprint might as well have put a Nelly ringtone on the phone.

I too think a lower key boot screen would be good, but the one there now doesn't actually bother me. As a grownup I'd like a more grownup screen but as a grownup I also have more grownup things to be bothered by.
[Epic 4G Android Development] tpike:
Hrm...
[Epic 4G Android Development] siirus09:
Although I disagree with those members here who are self conscious about what others may think of them because of what appears on their personal phone (America =/= freedom?), I do agree with the fact that as much as I love Rod's work, the boot logo is kind of over the top. As fami quoted, "Android follows the fundamental UNIX approach of "no news is good news", and there's a lot to be said for that tack." So if someone does a kernel copy of Genocide 1.1 with the stock image, Id jump on the band wagon.

Ive been using the new SetCPU with the UV and its working out fine. Ive never had a problem with SetCPU but VC had me crashing and freezing even at the lowest amount of UV. So, IMO just like any other kernel and ROM, use whatever works best for you but just make sure to give each a try =)
