I posted this in the Cog thread so I will post it here to for those using Cog.. With Cog 4.2 and up it automatically includes a S_volt_scheduler file (Cog 4.1 does not have it) and it sets all the states enabled but defaults max clock to 1ghz...if your having sleep/charge death, even if your not oc/uv'ing, delete this file ..my kernel will default states up to 1ghz only enabled and max clock to 1ghz.. I don't know if having all the states enabled even though max clock is 1ghz causes this, but there's been reports of people not having it with Cog 4.1 but it starts after 4.2, and this is the only thing I see that could effect it ... so having all the states enabled even if max clock is 1ghz and no oc/uv, could cause it...so try deleting this file and reboot..you can then either leave it or reset your oc/uv settings, but make sure only the states are enabled that your using ...let me know if this helps.. There has been very little reports of charge/sleep death except from people using Cog 4.2 and up ..this is the only difference I can find ...but of course if you UV to much it can cause this, so make sure that's not the problem..as well as if your imei falls under the bad batch of the ones that have a factory issue with sleep death.. there's nothing I can do for that

Sound only in the right channel during the call

When I use stereo headphones during the call I have sound only in the right channel.

I'm running KB1 ROM with eXistZ Captivate Kernel #8 on Samsung Captivate.

Reported bug in both Kernel thread and here.
[Captivate Android Development] lactardjosh:
Instead of USB, if you want to control the music through the phone, you can use xcaliburinhand's dock sound redirector while docked and connect through the aux in on the head unit.

https://market.android.com/details?id=net.muteheadlight.dockredir

Or you could not dock at all and just use the headset jack to aux in on the radio and it should work just fine.
[Captivate Android Development] Moxie3000:
I'm confused, though... According to the app page:

"Automatically redirects sound through the dock output when the phone is inserted."

Am I confusing something here? I assume when it says "dock" to simply replace that with "USB" because that's what I'm actually connecting to. If I'm connecting via AUX, why do I need an app at all? At that point, it's no different than running from headphones.

And yeah, I've seriously considered going from Headphone out to AUX, but don't have the cable. It's also one more cable to worry about having with me in the car. The way I'm setup right now, I've already got the charger cable getting in the way. If I chose to give up on USB audio output, then I'd have to go hunt for shorter cables.
[Captivate Android Development] lactardjosh:
This is in danger of heading off on a tangent, but when connecting to a dock, not just using a USB cable, for whatever reason the sound doesn't automatically get sent through the headphone jack.

The phone can tell the difference between a USB cable and a dock. I believe this is based on the pin arrangement, if I've gleaned enough understanding from other threads.

I just went out to my car to try out the USB port. I think I understand your issue better now. For me to play music through the USB port, I needed to mount the SD card so the radio could see it. You would need an app that lets you mount the SD card and still control what songs you are playing from the phone. I don't know if that is possible.
[Captivate Android Development] shane87:
To the best of my knowledge, that is impossible, as mounting the sdcard on the radio will unmount the sdcard on the phone. I have a similar issue with my phone. The radio I use will, for whatever reason, only pick up 369 songs, even though I have over 700 songs on my sdcard. And the songs it does pick up appear to be chosen at random.

After installing this, my screen rotation stopped working and is stuck in landscape mode unless I turn of auto rotation.

Any ideas?

Try to reflash with cwm only (no kernel flasher app) and clear cache and dalvik cache..first boot will take longer to rebuild the cache
[Captivate Android Development] 4-2ndtwin:
existz,

Just wanted to let u and others know that ur kernel has been working for me

flawlessly

for the past several days.

Running Cog 4.3 and was running Cogkernel, but had the sleep of death issue several times this past weekend and so flashed beta 8 and all has been great since--no deaths of any kind.

Appreciate all of ur time and hard work that u put in.
[Captivate Android Development] stratous:
Could you explain what you mean, I am a newb at this. I suppose I should not have flashed to the I9000

So how exactly do i take off the BLN? I'm new to this and im not sure how im suppost to do this.

No Joy Disabling BLN

I have tried every solution mentioned in this thread, including installing the script, and uninstalling BLN,and I cannot disable BLN.

So, I"m considering changing to the other Existz kernel (forget what its called at the moment).

I suppose I should post this question in that thread, but maybe Existz has thoughts here first. So, the question is, is there a disable BLN capability in the Recovery on your other kernel?
[Captivate Android Development] existz:
Try clearing cache/dalvik cache ..with the script added, also make sure to install busybox.. but as for my sp-voodoo kernel, no BLN is not selectable from recovery, but there is a no-bln version...as for my Onix kernel, yes bln is selectable from recovery... but try clearing cache/dalvik cache while using the script and see if that helps, something could be sticking somewhere and clearing cache/s should clear it out
[Captivate Android Development] RonH54:
Is Kernel just for Stock 2.2 or can it be used on Custom ROMs like Darky's 9.5?
[Captivate Android Development] ewingr:
​

Thanks, Existz. I'll give that a try.

FYI...I do have busybox, as I use Tibu, and have been for long time.

FYI...I really like your kernel. I am tempted to try th Onix. My assumption is I could use it on the UCKB1 ROM; and use a KB1 modem (Had lot of success on that in past).

I tried a Speedmod, I think it was , which somehow I got the impression I could use KB1, but static on BT made it unusable.

I do need to OC because I have so darned many apps installed. Like to UV for Batt.

FYI...with this kernel on Cog 4.2.1, set to 1400, and some UV, I am successful (ie no freezes), and batt use is ~ 1.5%/hr at idle with BT, GPS, and WiFI on.

I'm just having two issues: the BLN; and my WiFi keeps getting in error state when toggling with Tasker. I've seen a number of other people having the same problem on various kernels, and various ROMS, so I don't know what's up with that.

I'll post back on success of cache and dalvik clear.

[EDIT]

Something must be screwed up on my phone. I just tried to clear Dalvik, and I get the error:

ClockworkMOd recover v2.5.1.3 - Voodoo lagfix

E: Can't mount /dev/block/mmblk1p2

(file exists)

Salvik Cache wiped.​

Not sure what's up with that.

Also, by the way, I am in another thread about the WiFi Error issue, and someone posted that you attempted to fix that problem in Onix. Maybe I should just give it a go.
[Captivate Android Development] existz:
When you clear dalvik cache with voodoo recovery it will do that, it does clear it though...just ignore it..

As for the wifi error, im not sure what causes it, Hardcore put an attempted fix in k13d which was put it in Onix, some still get the error though.. But ive seen it happen way more with KB1 based kernels, not sure either as to why.. But if you switch to Onix and you still have issues, then def try clearing cache/dalvik cache and reboot router so it releases it.. Then try again, you might have to toggle it a few times but it seems after that its fine.. Ive noticed for me, when I get the error on KB1 kernel, I can reboot my router then toggle it a time or 2 and then it connects everytime after that...then when I switch to Onix or sp-voodoo it will do the same thing, then I do the same over, reboot router..etc..and then it connects every time afterwards..
[Captivate Android Development] ewingr:
I recollect you suggesting a reboot of the router some time ago, which at that time didn't help. But I'll follow your suggestions. I have a question on the Onyx with KB1 ROM and modem combinations, but will post that on the Onyx thread.
[Captivate Android Development] shane87:
For anyone having wifi issues, here is how I fixed wifi on CogKernel 4.3, and so far the fix seems to be working on beta 8 as well.

1. Go to Cognition thread, post 3771, and download the UPDATEDHCPCD-CWM.zip file.

2. Copy the .zip to your sdcard.

3. Make a backup of your dhcpcd. It is located at /system/bin.

4. Flash the updatedhcpcd-CWM.zip

Thus fixed my wifi issues once and for all. Also, as posted in the thread that the updatedhcpcd file is located, your results may vary, YMMV, and do this at your own risk, I , nor the author of the update, are responsible for any damages or bricks that may occur. However, I have been using it successfully fir a few days now.

ROM: Cognition v4.3

[Captivate Android Development] lactardjosh:
I also can't get BLN to stay disabled. I've cleared the Dalvik cache, uninstalled the script, reinstalled the script, reflashed beta #8, installed then uninstalled BLN.

Nothing working...
[Captivate Android Development] existz:
ill go ahead and make a NO-BLN version...atleast until I can get time to work on adding it to recovery
[Captivate Android Development] existz:
*UPDATE*

Added NO-BLN version...same as #8 just removed BLN completely
[Captivate Android Development] lactardjosh:
Downloaded, working great, tested with text and email.

Thanks!
[Captivate Android Development] ewingr:
Cool! :cool:

Many thanks. I'll be experimenting with the NO-BLN, and your Onix as well.

BTW...I cleared cache, and Dalvik, and can't speak to BLN yet, but only 1 test, my WiFi did work right. I may hang off changing for a day or two to see if WiFi continues to work.

stock

i wanna try to kernel out without overclocking.... is the default set to stock or do i have do another procedure if so can u guys explain...

thanks
[Captivate Android Development] existz:
Everything is set to stock by default
[Captivate Android Development] kdot25:
should i use the one with bln or no bln
[Captivate Android Development] existz:
That's up to you, depends if you want BLN or not (backlight notification)...otherwise they are the same
[Captivate Android Development] nedthehead:
People were complaining about BLN causing Sleep Deaths, so they requested a non BLN version. Personally, I haven't had sleep deaths with the BLN kernel so that's the one I'd recommend, but it's honestly up to you. There's virtually no difference other than BLN support.
[Captivate Android Development] Johnsondr80:
Hey Ex,

Just flashed v8 noBln last night. Just wanted to test the newest thing, thinking about adding it into the next fusion beta. Just needed to report, and hopefully help.

Stock fusion beta 1.8

No added fetures or apps,(except rom manager, and xda pre)

No oc/uv (yet)

System and data ext4

So last night after flashing everthimg looking great, watched tv for a bit and went to check battery drain while idle, still looking good, went to do a little surfing and e_mail checking; no connection, try again. I got the data symbol in notif bar, the arrows are showing up up up up(long) down a sec then stop. So I reboot and data works fine now, so I do what I need online testing drain on battery, very good. Plug in and go to bed.

This morning I wake unplug and wake phone to check time I notice that there is no H in the notif bar. So my cappy and I head for coffiee, while thats brewing I try a google search on local weather, no connection. I check apn settings, good; try to jump start data with a e-mail refresh, xda.....humm? Put it down and got my day started.....1hr and 15min later i'm in the car headed to work and I think to myself I need to reboot before I get to work, I grab my cappy unlock screen and hold power button a sec......wait! There it is the H and guess what... Data works now. IKN what to make of it.

Will continue to test and let you know if it persist. Side note, after flash I did wipe cashe and davik.

Edit: idk, yesterday at lunch it did it again but......today.April 5th the problem seems to have fixed itself. Maybe a settlement of kernal into rom issue. Anyway all is well
[Captivate Android Development] Hidyman:
Just wanted to say thanks for the No-BLN version.

It was the only thing I didn't like about the kernel (because it wouldn't stay off on boot). I wouldn't mind having it if it would remember it's setting.

This kernel is excellent, I use mild UV and OC to 1200.

No problems that I can see.

Battery life is fantastic.

Keep up the great work!! :)
[Captivate Android Development] Rrryan2:
For whatever it's worth, I think the beta designation for this kernel is unnecessary. I've used it for weeks and weeks and have yet to experience any problem that could be attributed to the kernel.

I've been disappointed that there's not more KB1 development in the community as a whole (am really that weird to love having the Audience chip working so much?) but at least I know I've got a solid eXistZ Captivate OC/UV kernel to use. :)
[Captivate Android Development] lactardjosh:
I found myself unable to live without the audience chip, too. KB1 development has slowed down a lot recently. If only I had any semblance development skills.
[Captivate Android Development] WheresWaldo:
I am also in agreement with the above sentiment. This has been one of the more stable kernels I have ever used on my Captivate. It is far better than some other "FINAL" versions.
[Captivate Android Development] Johnsondr80:
Agreed. I'm going to have to include this in the next release of Fusion. Currentlly I'm oc 1.2 and uv'd slightly. Most stable kernal of its hind IMO.

And I love seeing 100% battery for a while after charger removed. This morning with heavy usage

Great. Just great.
[Captivate Android Development] rajendra82:
Existz has indicated that he is going to port over the features of Onix into this one soon. He seems to have his hands full, trying to get that kernel to the next level of awesome. Once it has reached to a good code base, I am sure that he will pick the work on this branch, right back up.
[Captivate Android Development] Rrryan2:
Oh I don't doubt it. I meant it as a complement: this kernel is a lot more stable than its beta designation would tend to indicate. :)
[Captivate Android Development] msmalin1984:
Working great!

I recently flashed Cognition 4.3 but my device has been freezing up at random, at least once a day. I saw this kernel would fix the freezing, so I flashed it a few days ago and haven't had a single freeze since. No other issues either, the whole phone works perfectly. Thanks!
[Captivate Android Development] IDoMy0wnRacing:
Will this Kernel work with a JS8 ROM? Lets say Continuum v4; or is Onix the better choice?
[Captivate Android Development] Rrryan2:
Yeah, it might work but you'd need a Captivate modem (KB1) too.

Onix is probably the better choice for a JS8 base.
[Captivate Android Development] IDoMy0wnRacing:
Thanks

10 char
[Captivate Android Development] rajendra82:
Onix is the kernel Continuum v4 starts with, so newer versions of Onix, and other i9000 modems, than what's packaged with the ROM work out great. I am currently rocking Onix 2.0.5 and KC1 kernel.
[Captivate Android Development] golfslicer:
Install this on Firefly 2.8 works great with KB1 modem however, If I enable any security on my router, wifi will not connect. Yes, I have installed the fix from the cog kernel to update dhcpd, didn't help. Firefly did connect with speedmod kernel. I want the battery life with this kernel but the wifi not connecting is the killer. I can get wifi to connect via mac address also with this kernel, but I just can't enable the security. That would be ok, but if on a trip at a hotel, I doubt I could get this to connect since they always have to enter a password to connect to their wifi.

Any solutions other than flashing back to an i9000 based kernel. The Onix Kernel works fine, but I want the KB1 Kernel version please.
[Captivate Android Development] boog:
To me, it seems there is more to it than just matching kernel to modem, seems there is a few other things in the rom that need to be matched as well. (coming from the experience of trying to use i9000 kernels and modems on a kb1 rom)
[Captivate Android Development] thejanitor86:
i have cog 4.3 and i want to flash this in. but i am not sure on how to do that. do i have to do this with cognition. or can i do it after i have cog already. i haven't flashed just a kernel before.
[Captivate Android Development] WheresWaldo:
You can flash from Recovery without reflashing Cog 4.3.

When I did mine I just flashed everything at once, without rebooting. First flashed 4.3 then flashed this kernel, then flashed PlumbBob GPS fix. After everything was flashed then rebooted once and all was well. I suppose I could have replaced the kernel inside the Cog zip and saved a step, but it doesn't really matter.
[Captivate Android Development] Johnsondr80:
Any one.

I.be searched and read every post in this thread. Any one got the

"Remove s volt schedule.zip"

I've lost mine. Need it.

[Captivate Android Development] Johnsondr80:
With ur permission, I'm going to include this kernal on the next fusion release. It's working wonderfully for me.

Only think that would make me happier is to figure a way to set kb1 modem bands, can't get around RAT selection restricted. Wish I could learn to create/write/mod modems.

But that's another thread.
[Captivate Android Development] IStern:
I know this sounds weird, but is it possible to run this kernel + captivate modem on a i9000 rom? phoenix rising 4.0.3 to be specific.

Edit:

Just tried it, didn't work at all 8)
[Captivate Android Development] shane87:
I see that a Captivate kernel/modem doesn't work on an i9000 rom then. That's odd, because I am running an i9000 modem/kernel on a Captivate based rom. I know my signature says I am running kb1 beta 8, but I just haven't changed it yet. I am currently running onix 2.0.4 and the telus tljl3 modem. The really interesting thing for me is that the tljl3 modem does NOT support hsupa. I have it enabled, yet my max upload speed never goes above 300kbs. Of course I use wifi primarily, so its no big deal for me, just surprising.

[Captivate Android Development] meadhros:
Confirmed. I have run i9000 kernel and modem on kb1 successfully. I9000 with kb1 kernel and modem will boot. Then it will gradually deteriorate into the magical land of force closes and reboots. Had too much free time and experimented. Just don't accidentally put your backup kernel folder on your external SD card.

Increasing File Speed Within The Kernel Source Code...

EXistZ,

In regards to a few posts written by you in an alternate thread, in respect to fusing some code into the KB1 and Onix Kernel source, I was curious as to your views on this method of approaching the result.

To me, this does make sense to look at coding the source in this sense as compared to what was written throughout this thread and other threads written relative to this same method.

How I understand the methodology is that instead of using a higher predefined value, which locks on boot and stays until modified, to achieve a read-ahead value for a a smaller file or directory, the route in which the this code is targeting the memory blocks, is less intrusive and more specific to specific areas of the file structure.

In other words, setting a manual predefined increase in cache value, say 2048kb (128kb default) to read files and / or directories ranging from 4Kb to 800kb for instance, I would tend to believe that this would potentially cause an adverse reaction at some point by flushing the unused portion of allocated read-ahead cache space back to memory. Performing this action over and over again at a quick pace would cause a sort of buffer overrun and result in lag reading these specific areas of the file structure. Whereas by specifically targeting the memory blocks directly, not just the cache sizing element, and specific to their exact functions, unnecessary buffering and potential lag could be greatly minimized if not eliminated. - I won't even touch the subject of heap sizing or heap throttling in conjunction with the read-ahead speeds in this post.

I don't believe this post to be off topic to this thread, being that my enquiry is specific to this kernel sourcing.

Having a huge background in technology as a computer and network engineer I know that there are always multiple ways to go about achieving a specific result. Some ways are better suited for the environment you are working within and some alternatives leave open ends or opportunities for failures in other aspects of the file structure which lead to poor performance at best or a file system with a major handicap.

I am currently experimenting with a few ideas of my own to go about this process... nothing to mention as of yet, just preliminary ideas a work, so to speak.

If you would be kind enough to elaborate on this topic, I was curious as to your views on this type of allocation of speed increase as compared to increasing the cache sizing of the SD Card to give the illusion of greater overall speeds.

I'm looking forward to your responses.

Thanx eX, keep up the great work.

Peace-
