If i have to go back to stock first I'll just wait until the Boss v3 is out so I only have to mess with this once.
[Epic 4G Android Development] 350zfern:
I am getting an error "E: Signatuer verification failed installtion aborted"

What do I do to correct this?
[Epic 4G Android Development] ipaq3115:
You don't have to go back to stock you just have to remove the root and CWM with the scripts that are in the posts that you got them from. Then you can apply that update it's prompting you for.
[Epic 4G Android Development] nitroxeno:
Or you can just use the Non-Stock update here: http://xdaforums.com/showthread.php?t=797090
[Epic 4G Android Development] Geniusdog254:
You have to flash with ClockworkMod Recovery, stock recovery won't work.
[Epic 4G Android Development] ipaq3115:
Yeah, that's the one I linked to... I'm pretty sure you have to be on DI07 before you use that though. Maybe not, I just thought I read that somewhere.

Just wanna say, I flashed this kernel with cw, coming from andromeda kernel, stock rom, not using setcpu. Really impressed with the performance, and has been perfectly stable. I'm not sure about battery life yet, but still watching it. Sitting mostly idle this morn, from 6:00 til about 10, I did go down from full charge to 82%. But that could have been attrib to a battery widget I was running. Voodoo at 100% is fantastic. Thanks GD

[Epic 4G Android Development] 063_XOBX:
Since I flashed this kernel a strange bug has appeared (or perhaps become more apparent). Sometimes when I open the notification shade the brightness of the screen drops to 50-75% which is very annoying since the blue tint returns. Anyone else have this or maybe even a solution?
[Epic 4G Android Development] Geniusdog254:
Not a bug.. It's a "feature" (and I emphasize the quotes there) from Samsung. Slide your finger across the bar, brightness changes. If you just slide straight down on the bar instead of in a slant (like we all typically do) then it doesn't change.
[Epic 4G Android Development] 063_XOBX:
Wow. That is an even more annoying "feature" than the touchwiz samsung so generously gave us. There doesn't happen to be a way to disable it?
[Epic 4G Android Development] ElT0R0:
Just installed the kernel over stock. Feels much snappier already. Going to test for a day or so before setting up setCPU on it.
[Epic 4G Android Development] mattallica76:
If you enable auto-brightness, it will disable it.
[Epic 4G Android Development] mattallica76:
I you installed the voodoo version, I don't think setcpu is necessary as the overclock is already enabled.
[Epic 4G Android Development] 063_XOBX:
But then I won't be able to use the Voodo color fix since it's only for 100% brightness
[Epic 4G Android Development] roghaj:
I was able to use the built in mic while I had the phone plugged into my AUX on the stock version of DI18. I updated to this, and now it doesn't work. Bumber

[Epic 4G Android Development] dmlee:
Anyone else notice that the screen brightness is a bit wonky if you have your display set to minimum brightness?

Mine just started doing this with the updated kernel.
[Epic 4G Android Development] Geniusdog254:
Yeah minimum brightness is tweaked lower, since the default was still far too bright in a totally dark room for me & MANY other users. I said before if I got too much negative feedback on it, I'd remove it, but so far all but two or three people loved it. If it's that big an issue just take it one tiny step above 0 on the slider & it's fixed.
[Epic 4G Android Development] dmlee:
Oh no, I'm lovin it! The minimum brightness was way too high, I was just wondering if you knew about the brightness changing sporadically.
[Epic 4G Android Development] NYYFan325:
Maybe I missed if this was previously discussed, but why is the OC only pre-set in the voodoo kernel and not the non-voodoo? SetCPU has given me some issues previously and I'd like to avoid it if possible, anyway to add the 1.2 to be the standard on the non voodoo?
[Epic 4G Android Development] ElT0R0:
Oh, it is? I did not realize that, but yes I did install the voodoo version. What's the best way to check the CPU speed?
[Epic 4G Android Development] Geniusdog254:
Well, actually thats a bug. Lol my bad :o I think I only applied it to the governor on one kernel and not the other since I maintain two kernel trees (one for each kernel) I'll fix it in the next release.

Changing on it's own? Or when you're touching the screen? If its when you're touching the screen it's Samsung's fault. They do weird brightness stuff everywhere from the browser to the statusbar and I can't do a damned thing about it since it's in their private code.
[Epic 4G Android Development] joshottley:
You should keep it. It runs great!
[Epic 4G Android Development] NYYFan325:
I think what he might be referring to is on the voodoo kernel when the screen would normally dim before it shuts off it actually gets brighter instead. I know you said you lowered the stock 0% brightness (which is great) but the screen actually gets brighter (back to the normal 0% i believe) right before the screen shuts off
[Epic 4G Android Development] dmlee:
Yeah, that's exactly what I'm talking about.
[Epic 4G Android Development] Geniusdog254:
Thats the level Samsung has set in the framework to go to right before the screen goes totally off. I'll see if they pull it from the kernel or the framework & fix it if I can'. If not, its only there for what like half a second before the screen locks? ;)
[Epic 4G Android Development] NYYFan325:
Ehh like 3 seconds but whos counting lol

It's not a big deal, I was just trying to clarify dmlee's question a little more :)
[Epic 4G Android Development] dondadah88:
This feature only happens when ypi slide the bar to the left no right.
[Epic 4G Android Development] dmlee:
Is the adjusted minimum brightness not available in the novoodoo version of the kernel?
[Epic 4G Android Development] tommi_han:
Anyone have trouble playing 3d games with this kernel? Overclock kernel crash with necessary battery pull every time
[Epic 4G Android Development] michaelw9:
I put in the new kernel tonight with the Voodoo mod and now the screen brightness is behaving very sporadically, as well. I have it set to automatic brightness. It used to do this pre-DI18 but very very seldomly, now it's all the time.

But it will just randomly change from whatever the auto-bright chose to extremely dark (almost impossible to see dark), if it's bright out. Then you'll use it and it will just suddenly come back to a medium brightness level selected automatically.

If you turn off the auto-bright and set it to something else, it stays put at that chosen level.

And curiously, when you hit the power button to unlock, it shows normal brightness for just a hair of a split second before showing the passcode-screen to unlock.

Help please...Can't flash kernel

Help Please….

I am new to flashing kernels or ROMs. I have been trying to get this done on my Epic. I have wasted many hours trying to get this to work on my own including combing forums for information but I am stuck.

I have rooted my phone using one.click.root.exploitv2.2.6. The root worked as I have been able to run apps requiring root.

I loaded ClockworkMod ROM Manager many different ways. If I try to boot into recovery mode from the app I get stock recovery mode (blue text) and I always get the error messages “failed to verify whole-file signature”, “signature verification failed” and “installation aborted” while it is trying to load the ClockworkMod update.zip.

If I start from power off and press vol down, camera and power buttons I get into stock recovery (blue text). From there I can run update.zip which gets me into ClockWork recovery (green text). So far so good…I think.

From Clockwork recovery I try to flash this kernel…I select “install zip from sdcard”. I select mixup-20101005-1119-voodoo.zip…confirm install….

I get the following messages:

ClockworkMod Recovery v2.5.1.0

-- Installing: SDCARD: mixup….

Finding update package…

Opening update package…

E:Can’t open /sdcard/mixup…zip

(bad)

Installation aborted

As I have been flailing…I even tried the commands at the beginning of this topic thinking that there is a problem with my one click root. So I executed the following…

adb shell

remount rw

rm /system/bin/playlogo

rm /system/bin/jk-su

mv /system/bin/playlogo-orig /system/bin/playlogo

This undid my root. So I had to run one click root again…

Help! I know it shouldn’t be this difficult.

Thanks.
[Epic 4G Android Development] ipaq3115:
I used the one click method for loading clockwork and it seems to work fine, I'm not sure about the method you're using.

I have had that error when flashing zips before, but it just turned out to be a bad download, I just had to redownload it and it worked. Not a problem with your root.

I believe that root fix is for an old version of the root method, not the new ones.

Sent from my superphone using the XDA App
[Epic 4G Android Development] robl45:
I second this, if you are getting that, its a bad download. most likely didn't download all the way.
[Epic 4G Android Development] sstea:
Thanks! You guys were right. I downloaded the file again and it worked this time...I am not sure how the file got corrupted in the first place but that was apparently the problem.

Since you've been so helpful let me ask a couple more questions.. ;-)

How do you use "voodoo". Is there anything else cool to do with this kernel besides overclocking to 1.2Ghz?

Thanks.
[Epic 4G Android Development] sstea:
My initial impressions. Seems fast and stable. Kudos to those that make this possible.

On the downside automatic brightness is a little bit messed up. The level is too low and auto brightness is often slow to adjust brightness up. IMO it is much better to err on the side of being brighter than to have that beautiful AMOLED screen overly dim and yellow in normal indoor lighting. :(
[Epic 4G Android Development] ipaq3115:
Haha I just asked the same thing a little ways back http://project-voodoo.org/color
[Epic 4G Android Development] gophergun:
I agree. The lowest brightness is at a good level I think, perfect for use at night, but it doesn't readily scale up, staying at what seems to be that same lowest brightness in a reasonably well-lit room, or jumping between something almost slightly too bright and not nearly bright enough.
[Epic 4G Android Development] ZenInsight:
I have to say that while the Automatic brightness is definitely darker than the 0% setting on the phone, that is the only way I can get it to go that dark and if you leave it in auto and you are actually in bright light (sunlight or direct light) then it WILL raise the brightness. I want that minimum brightness when I am in a very dark room at night and wanting to use the phone but not disturb my gf. SO...if a change is going to be made, please don't remove that minimum brightness option for those of us that use it. Make the 0% that dark if necessary but don't remove the option. At that level of darkness we won't ever get a perfectly accurate color display anyway. I love this kernel. To me, it's perfect (using SetCPU). Just my opinion.
[Epic 4G Android Development] Geniusdog254:
How's the new kernels working out battery wise for everyone?

Any bugs (excluding the brightness weirdness, I'm working on it)?
[Epic 4G Android Development] DevinXtreme:
So, how about adding mkswap and swapon so I can get Swapper2 working? How hard would this be?
[Epic 4G Android Development] Forcystos:
Actually for me it's not even as close as I had expected... Full charge to 85% from 9p to 10p. Powered off at 10, switched back on at 9a, little to no usage until 3p went to about 60%. 3p to 5p heavy usage, 10%. Plugged in at 6p, unplugged at 7p, battery stayed practically the same. Oh, forgot to mention it was underclocked to 800mhz since 9a.

EDIT: my definition of heavy being web browsing with screen on all the time
[Epic 4G Android Development] Geniusdog254:
Weird.. Android has always been super finicky about battery life though. It could be that. Any apps running in the background? How was signal in the area, since that has a major affect on battery life.
[Epic 4G Android Development] Geniusdog254:
That should be doable. I'll have to look into it. If you have any info on it'd be greatly appreciated ;)
[Epic 4G Android Development] DevinXtreme:
Well, it's supposed to be in busybox 1.17.2, but it doesn't ever seem to be standard in the Android builds. All the binaries and source files are available on the busybox git, under util-linux, but because I can't even get my kernel to compile (the compilers says it finishes without error, but there is nothing in the output folder...), I don't think I'll be able to get this added myself.

This seems to be the only hurdle needed to be jumped to get Swapper 2 working. The busybox download from its app fails as it is right now. I'm gonna do a nandroid and see if I can't force it to work using tools I do know how to make work.
[Epic 4G Android Development] Geniusdog254:
I'll look into it. If you can get me a pre-compiled version it'd be uber-simple to throw into my ramdisk & install on boot ;)
[Epic 4G Android Development] DevinXtreme:
Forgive my ignorance, but aren't those .c files precompiled? I've got no problem viewing their source...

CM6's git has it all available, too. I don't know if there is a difference (not able to look right now...), but I'm pretty sure it just needs a full busybox.
[Epic 4G Android Development] ericizzy1:
donated, thanks for a great kernel.

keep em' coming :-)
[Epic 4G Android Development] Geniusdog254:
Haha my bad, I just found the precompiled binaries for ARMv6. I'll check it out and see if it works. If so it'll be in my next release.

Thanks! Already working on next update :)
[Epic 4G Android Development] Forcystos:
Running nothing on the background, I always close all processes after I'm done using the phone, aside from LauncherPro. What does give me some suspicion is I have auto-sync enabled and linked a Facebook account, which might be doing some damage. Also, I haven't observed signal strength in the areas I travel to, but I'll look into that too.
[Epic 4G Android Development] flyers2114:
Batt life has been great for me....I got 9 hours with HEAVY USE.......bt stereo with streaming for at least 6 hours....constant texting and web and downloading the 1,1.8 rom from Schizno.....and dl some other stuff also....i know that if I just used it normal I would double that number...the weekend will show it....thx for the great work!!!
[Epic 4G Android Development] DevinXtreme:
Sounds good. If you need any help or testing, let me know. I actually know some C/C++ :)
[Epic 4G Android Development] NYYFan325:
Battery has been good for me too, not too sure if its much better then say the stock or noob's kernel.

From 10:15am to 6:45pm I got about a 42% drain. Good amount of texting, light web surfing and that's pretty much it.

I have a de-odexed rom, battery % mod, vanilla lock screen, also removed a good deal of stock apks. I use ATK to keep running processes to a minimum.

Hope that helps ya.

Help, Auto Brightness Not Functional

This kernel has been fast and stable but very erratic on autobrightness.

Now auto brightness is completely non functional on my phone. If I set on auto my screen stays fixed at the lowest brightness. I can hold it up to light bulb and it won't increase the brightness. For the time being I have keep the brightness off of auto to use my phone.

I have rebooted several times and autobrightness still won't work. If I turn the display on and off a few times sometimes it will come up to a reasonable brightness but if the ambient lighting gets low enough or if I hit the home button it will get stuck at minimum brightness.

Is there a version of this kernel that doesn't mess with the auto brightness? If not please tell me how I can get back to the stock kernel.

Thanks.
[Epic 4G Android Development] jeffyv2:
Just flashed this will report once I get sometime with it..
[Epic 4G Android Development] shinma6980:
Ya I'm in the same boat. If I'm stuck on the lowest brightness, I'd rather just have the stock kernel back. Not enough noticeable difference to justify manually adjusting the brightness myself - and leaving it at an un-necessarily bright level would negate the supposed battery increase.

I do appreciate the effort of the developer. As a side note, I've noticed that sometimes in a bright area, when I let the screen time out something weird happens. Normally, the screen should be lit and it will dim when timing out. Since having the kernel the opposite happens. It's stuck on lowest brightness and when it's timing out, the screen gets bright before it shuts off.
[Epic 4G Android Development] jfg69:
I'm getting random flashes of brightness and then dim screen. Sometimes the screen lights up after its gone to sleep and then goes back to sleep after a few seconds.

On another note, I flashed the "novodoo" version but I still see it listed as a voodoo rom in my phone. Hopefully the answer isnt posted previously in the thread, I'm at work and not able read the whole thread.

All in all, great ROM thanks for all the work your doing for us.
[Epic 4G Android Development] Geniusdog254:
The Voodoo version showing on non-voodoo is a fail on my part. I left the wrong line in my init.rc. It's fixed for my next version lol.
[Epic 4G Android Development] TheRob44:
...

Hey, Geniusdog. First off, thanks for all the work you put into this. I've had it flashed since yesterday and it's been very stable. However, the battery life is significantly(!) decreased since I flashed this new kernel. Everything else is the same and my signal and everything is consistent since I noted the difference while at work. I have no idea what might be causing this, but it's a very noticeable difference. Something is eating the battery up very quickly.

Thanks again and I look forward to the next version!

Auto brightness...

Geniusdog,

First thank you very much for your work on this. It is very cool to be able to tweak these phones and get the most out of the hardware.

Do you think you will be releasing a version that addresses the auto brightness issues or leaves the stock algorithm as is? Is there a link that somebody can point me to if I need to flash back to stock kernel?

Thanks.
[Epic 4G Android Development] Geniusdog254:
I'm tweaking it in my next update.

my phone is locking up. I didn't gave this problem with tort last kernel. I wonder if its rom related or kernal related. It also seems to only happen when I check my text messages
[Epic 4G Android Development] akijikan:
I completed my first run after full charge, battery stats reset, full drain and another full charge.

Voodoo Kernel Stock ROM DI18 w/ DRM apks removed.

Phone came off the charger at 5:20 this morning immediately after the fully charged message popped up.

Significant use included around 60 holes of Let's Golf (3d gameloft golf game).

About 3 Hours of wifi being on.

Installing and playing withe fennec beta about 45 minutes

watching a few 10 minute youtube videos on wifi in HQ

not many calls today (couple <2 minutes)

It's 12:20 (20 after midnight) now and the phone just turned itself off. That's right at 17 hours.

I am pretty happy with this battery life. It's not epic, but if I hadn't played so much golf, I'd probably still have a good bit left, and this can certainly make it through a day.

Also with respect to the kernel in general, it feels good, snappy. Back-lighting is behaving oddly but that seems to be well documented.

Keep up the good work.

Battery life

My battery lif eover the last 2 days has been alot worse. Like getting the message to charge the battery with less than 8hrs since charging. I don't use it too heavily during the day. I have the stock rom and flash MixUp 2 days ago. Everything else is the same besides the kernel. I changed my Wifi back to sleep when the screen is off again instead of always on to see if it makes a difference. I am connected to Wifi all day. I am running the Voodoo OC kernel.
[Epic 4G Android Development] sunrocket:
I had the joekim 'one click root' installed on my phone. I removed the root per the instruction in the first post. After installing this kernel, I don't have the root anymore (setcpu, wifi tether etc are not working).

What do I need to do to get my root back? I thought the root was built into this kernel.

Bad service area

How does this rom run in areas with poor coverage that require a lot of power to get signal strength? I'm curious because I think the undervolt might affect this and I dont want to run it if this is the case. Thanks
[Epic 4G Android Development] Geniusdog254:
I have poor service in my area, and I run it daily. My battery life is of course lower when I'm in a low service area.

See, at home I get good service and on weekends I can easily go all day on a charge. During the week going to school though I get very poor service (0-1 bars Sprint, 0-2 bars roaming) and I have to plug in around 4PM. That's about 10 hours at school vs 14-15 at home. Not terrible, but you will have to charge halfway thru the day. I'm not sure how that'll compare to stock for you.
