[Captivate Android Development] hardcore:
Thanks for the info. I was wondering about that too, why 0x0098 instead of 0x0000, but I guessed it must have been the default value on powerup as you said. By changing the 0x98 to 0x00, I did intend to disable the DRC, QR and Anticlip.

Looking forward to the next releases.

BTW, I was trying to see if I could enable voice calls via normal 3-pole headphones. If you could detect via the driver if a headphone is plugged in or not, you could edit the voice call function to route the voice playback audio to the headphones instead of the receiver (and leave it on the receiver if no headphone is plugged in). That would be a nice feature.

I still want the phone-pc boot screen :D
[Captivate Android Development] silverslotcar:
That was Glitterballs who was going to do a phone ! pc boot screen with his kernel. Hardcore's is the Samsung SGH-I897 captivate boot screen, which is awesome in my opinion.
[Captivate Android Development] LimaI896:
Nope just texting, web browsing, tapatalk n xda app. No calls, maybe 10mins of gameboid. Autobrightness is set. I'm running serendipities 4.3 and jl3 kernel. I'm going to try a flash with the.steps you suggested to see if there is a change.
[Captivate Android Development] RonH54:
I just had odd problem. I had Speedmod Q on Darky 8.1 with Lagfix enabled. I decided to disable Lagfix so I went to Recovery and SpeedMod Options and Started the Disabling Process. All was going well it Showed backup completed and all the Switching to New Config and Creating and Mounting. Then last few things are this:

Mounting to Test

unmounting again

Restoring data

Checking MD5 sums....

Restoring data...

Then I have froze for 30 minutes at:

data@app@Cath.apk@classes.dex

What should I do?

Thanks

Grr, turns out that my comp decided not to function properly at that time. After i posted, no usb device was working anymore. Sorry if i misslead anyone
[Captivate Android Development] krazyphire:
And you battery died doing just that in 7hrs? Wow thats what I'd consider moderate usage at best. Yeah I would just reflash and wipe the cache. Also I know the JL3 modem doesn't have the best battery life so maybe switch to JK4 or KNP1
[Captivate Android Development] joeshmoe08:
Hey hardcore, I know this kernel doesn't need it and is great as it is, but are you ever considering making an oc/uv version of this kernel? I mean keep the normal ones but add an oc/uv one?
[Captivate Android Development] supercurio:
Yup! It's a feature a requested a lot! I received a pull commit about that earlier today and will investigate :)

If it works it will be in the next driver release ^^
[Captivate Android Development] smokestack76:
Ahh yep. Change kernels so often cant keep up with myself lol
[Captivate Android Development] gordec:
Just a newbie question. If I just flash kernel without going into recovery to activate the different tweaks does speed mod add anything?
[Captivate Android Development] keitht:
The Voodoo sound quality is not near as good as before. The bass is severely lacking where the earlier version sounded much better. Hope this changes. The highs seem to be ok but overall, the sound experience sounds muffled at higher volumes. This is a huge difference to how things sounded before. It is not very pleasant in current state. Appreciate the work but this is a big step backwards. I think you need to go back to the settings before.
[Captivate Android Development] jjtitus098:
I don't think an oc/uv version is needed. This kernel is so fast and stable as it is, I see no point in it. That's just my opinion though
[Captivate Android Development] disellusional:
were you consistently web browsing? I find if i am + games my battery life is a lot shorter
[Captivate Android Development] joeshmoe08:
Thats true which is why I stated that in the post, but I really think the undervolting mainly could help in battery life. For example, although glitterballs kernel wasn't specifically designed for battery life like this kernel (Based on OPs) I get equal or better battery with gb's kernel with 50 75 75 100 125 125 uv. I just think that, on top of this kernel would result in much better bat life.
[Captivate Android Development] Gurgs:
I respect your opinion but I use this kernel because I do not want to OC or UV my phone...No matter what rom I use it will be running this kernel. This kernel is perfect as is in my opinion just as glitterballs is a perfect option for someone that wants to do those things.
[Captivate Android Development] Fortune090:
I wasn't and my battery life's been fine, though it is recommended to avoid battery stat issues.

There's actually a tweak in there that helps your battery life. ;) I have all tweaks enabled and my battery life has been amazing. Been losing only around 3-4%/hr with use.
[Captivate Android Development] thindery:
just saw the 256 went up. What are differences between the 256 and 500?
[Captivate Android Development] existz:
From the FAQ in the OP....

NOTE:

After Hardcore done some testing, he stated there is NO battery difference between the 256hz and the 500hz..
[Captivate Android Development] Fortune090:
There's also a FAQ in the OP as well. ;)
[Captivate Android Development] waiting4gingerbread:
nevermind keep up the good work! :)
[Captivate Android Development] pinoymutt:
That's kind of what I was afraid of. Moving away from JJ4/JI6 may introduce some of the other little issues that prevented me before from moving to an i9000-based ROM (like voice static, bluetooth, etc) -- but I know many have been ironed out, so I may still mull on this one.
[Captivate Android Development] MS3Zoom24:
I must have I was tired last night when i was messing around with this. I was wondering why I felt so stupid LOL.

DLed the correct kernels now.

Sorry everyone

Now lets see if this works better huh, yes i think it will
[Captivate Android Development] thindery:
Ahh don't know how missed that in the OP, see it now. Thanks for pointing it out.
[Captivate Android Development] diablo009:
Could you pls tell me what that tweak is?
[Captivate Android Development] existz:
Its the Misc/Battery Tweak under Speedmod..

ALSO in the OP...

Clicked the non existent thanks button on xda app.

Crazy how I missed it out.
[Captivate Android Development] thindery:
I do have that message and I keep selecting the "No, enter recovery mode" option.

Then I get to another recovery screen and I can select "reboot system now" and when i do that it completly reboots but goes back to "configs differ, continue with conversion?" option where I can select "no, enter recovery mode."

what's going on here...?

EDIT:

I forgot to enable the ext-4 lagfix for all. After I did that I was able to reboot into the sytem with no problems.
[Captivate Android Development] existz:
You need to select no delete new config if you dont want to change your file system

If you selected a new lagfix then you will need to select, Yes backup and restore, to keep your new settings

I see mad battery improvements. Running this kernel with eugenes ginger clone r5 and have the best battery life I've seen so far. I've used xcaliburinhand and setiron 1.4.3 and this tops them.

[Captivate Android Development] :
Sad to say Im still running the stock 2.1 rom that came with my Captivate *insert noob joke here*. Im wanting to flash to the Phoenix 1.0 ROM and I know Im going to need an updated kernel too.

This one looks like a win to me... my question is, do I need to flash my 2.2 ROM first, or this kernel first?

Also, I know everyone has a preference for their modem... but whats a good modem on AT&T in Southern California?

Thanks guys.

Since u say u r a noob, I'll recommend trying flashing a few different roms. This will give u an idea of what might be best suited for u, and make u wary of the pitfalls u may encounter.
[Captivate Android Development] Dungeon47:
So far it has been great. I went to get groceries, and I keep my screen on pretty much the whole time, as I have my list on my phone. Two hours saw less than 20% battery usage; may have been more like 10%, I wasn't sure what level it was at when I unplugged.
[Captivate Android Development] :
Thank you for your advice, although you really didnt answer any of my questions. I am wary, hence the reason I havent flashed yet. Im taking my time to gather as much knowledge as I can to reduce the risk of something going wrong... and it seems that the promised 2.2 update is never going to come.

I appreciate you for giving me helpful advice though. Thanks button clicked.
[Captivate Android Development] Eibon:
So what is the battery and speed differences between the 250 and 500 hz versions. I'm planning on flashing one, but don't know how significant of a speed boost versus how significant of a battery increase each one offers.
[Captivate Android Development] Spidious:
How do I do the below ?

Reflash the final K12Q in the OP (DONE)

Then clear your dalvik cache and wipe the main cache as well. (HOW/WHERE)
[Captivate Android Development] mcord11758:
Clockwork recovery

Main screen clear cache

Davlik under advanced clockwork options
[Captivate Android Development] xreflection:
You can do this in clockwork recovery. Reboot into recovery and then go to Advanced ClockworkMod Features -> Wipe Dalvik Cache. To wipe the main cache, it should be wipe cache partition in the main menu of recovery(I THINK).
[Captivate Android Development] Spidious:
I see, It must not show up till you restart it after starting up lagfix ?
[Captivate Android Development] xreflection:
Do you have clockwork recovery installed?
[Captivate Android Development] Spidious:
Found it

Did it

Thanks guys

Isn't this phone amazing !

Just imagine 30 years ago having a phone that could do what this phone does, hey didn't they do that on a show called "Star Trek" ?
[Captivate Android Development] reinbeau:
Regarding lagfix

Is it enabled by default? Or does it have to be enabled? I thought it was built into the ROM, but it's the kernel? I'm a bit confused, please educate me :)
[Captivate Android Development] mcord11758:
Is what enabled, the lag fix?

It depends on your state prior to flashing. If your system was already on extension 4 partitions then yes. If not, no. go to recovery, advanced ulk, lagfix. The bottom should tell you your state. If it reads all rfs lagfix is not enabled. All ext 4 its on.

To enable select.......enable ;)

Go back, reboot, tells you you have changed your settings, select yes
[Captivate Android Development] Spidious:
I don't think it is enabled by default.

But if you already have it enabled and reflash the "Q" rom it will stay enabled.

Just be sure and enable the tweaks with the (R) by them...

If I am correct.......
[Captivate Android Development] reinbeau:
This is what it says in the Advanced ulk lagfix screen:

At the top

-Disable lagfix: Convert DATA to RFS

-Enable lagfix: Convert DATA to Ext4

-Convert SYSTEM

-Advanced custom conversion options

-EXT4 mount options

+++++++Go Back+++++++

ClockworkModRecovery v2.5.1.0 SpeedMod ULFK

DATA_FS=ext4

CACHE_FS=ext4

DBDATA_S=ext4

DATA_LOOP=false

CACHE_LoOP=false

DBDATA_LOOP=false

BIND_DATA_TO_DBDATA=false

So I guess it's enabled :confused: :)
[Captivate Android Development] mcord11758:
Enabled...
[Captivate Android Development] LimaI896:
Doing bit better with this charge after flashing fresh and clearing cashe. Heavy usage then before. Right now I sit at 37% for 6 hours and 10 mins I listened to the radio for 40 mins via BT, then Music for an hour via BT while playing gameboid for 20mins, Several texting, tapatalk, xda reading, uploading photos, facebook, 1 10min phone call.

I dont like the JK4 modem for call quality though battery was better on it. Maybe I'll give that other one a try.
[Captivate Android Development] xreflection:
Looks like its enabled. Did you have a previous speedmod kernal with the lagfix enabled?
[Captivate Android Development] xreflection:
did you calibrate the battery before you got those numbers?
[Captivate Android Development] evrionis:
flash from stock 2.2 ROM with setiron kernel

I currently have a stock captivate rogers 2.2 using a SetiroN i9000 SuperOptimized v1.5.6 kernel with Ext4 lagfix data enabled.

Do I need to diasble lagfix to install this kernel?

Can I flash this kernel ober the setiron kernel or do I have to flash the original back first?
[Captivate Android Development] xreflection:
You should be able to flash over setiron, but I'm not sure about the lagfix.
[Captivate Android Development] evrionis:
I was hoping to be able to flash between the 2 to find out which one is better for me.

xreflection: I see you are using the speedmon. Have you tried the setiorn? If so, what is your opinion of the 2?
[Captivate Android Development] mcord11758:
Both kernels use ext 4, uot should be fine
[Captivate Android Development] evrionis:
Could not see much from the log's of both.

Does either one provide better Voice and/or GPS and/or WIFI capabitlties? Or is that mainly coming from modified ROMs. Which I will tackle later one day.
[Captivate Android Development] kennethpenn:
K12Q is pure awesome. Loving the new boot image with I897 branding.
[Captivate Android Development] mcord11758:
Sound us much better with this kernel as it is using voodoo sound v2. Gps, wifi are more a function of the modem you use
[Captivate Android Development] evrionis:
How can u tell what kernel you are using on the phone?
[Captivate Android Development] Gurgs:
Settings...About phone...Kernel version...
[Captivate Android Development] evrionis:
Thats what I thought, when I installed the setiron kernel, It still says....2.6.32.9 which looks like the stock kernel.
[Captivate Android Development] Gurgs:
I think 2.2 roms are only capable of showing that line and 2.2.1 roms allow for the second line to be shown...or something like that. No matter what kernel you are on 2.6.32.9 will be there on the top line...
[Captivate Android Development] evrionis:
Thanks..

I guess is there another way with some root tools?
[Captivate Android Development] mcord11758:
In this case there are two signs as to what kernel you are using

Hardcore does not allow oc so voltage app won't work

Sent does not allow voodoo sound so voodoo control app won't work
[Captivate Android Development] Spidious:
Just noticed my app home button disappeared.

Also Keep The Lights On stopped working
[Captivate Android Development] WickedNite:
Mine's working fine. Try uninstalling and reinstalling the app and see if that works.
[Captivate Android Development] Aus_Azn:
Apparently my lagfix was not enabled. How about that?

Do you recommend converting /system to ext4 as well? I noticed that this kernel doesn't include it in the default lagfix.
[Captivate Android Development] MikeyMike01:
I did. Haven't had a problem.
[Captivate Android Development] johan8:
By default /system is Read-only partition and you won't able/need to write anything into it.

so covert it to ext4 is not necessary.

All user data, program settings are all store in 2GB /data

On the other hand if you want to stay away from RFS, it is ok to convert to ext4 too.

ps. there are total 5 partitions in GalaxyS are in RFS
[Captivate Android Development] Damager:
which version is the one with the better audio?
[Captivate Android Development] supercurio:
Hi!

Beside the +1.5dB SNR option and 128x oversampling (configurable), everything else how the hardware is configured is the same in version 2 as in version 1.

Which means the output signal is identical, resulting sound as well.

It's a perception issue, don't worry, it happens a lot as perception is influenced by fatigue / brightness of the room, environmental noise, emotions and also the listening volume (higher volume = give the impression there is more bass)
[Captivate Android Development] LimaI896:
Nope didnt know you could do that or if it even worked.
[Captivate Android Development] keitht:
Hmm.. maybe I need a drink or two. :)
[Captivate Android Development] reinbeau:
I've never fiddled with kernels until this one, I've just always used what came with the ROM. Thank you all for your help!

Just installed speedmon k12q 500hz cwm.zip... On my cativate rogers 2.2 stock ROM.

[Captivate Android Development] ccdoggy:
What is the battery life difference between the 250 and 500 versions?

I am using the 250 right now assuming it will save me some battery as battery life is critial for my phone right now, but if the difference is negligible i am all for smoothness of 500.

thanks.
[Captivate Android Development] :
250 is the default Samsung setting. 500 seems to be smoother scrolling and has no effect on battery drainage over the 250 setting. 500 is the way to go... you get better scrolling and you dont have to give up any battery life for it.
[Captivate Android Development] WickedNite:
+1

Couldn't agree more.
[Captivate Android Development] ccdoggy:
Thanks for the info. will flash the 500 version soon.

One more question, does BLN use much battery time? there was a post or two I saw in the phoenix thread that BLN uses some battery even when not on and so the dev even suggested not to turn it on for better battery life.

Is this true or just smoke? difference negligible?

Thanks again.
[Captivate Android Development] WickedNite:
I think it uses some battery, but not that much though. You could test it out with and without BLN so you would notice the difference by yourself.
[Captivate Android Development] Exostenza:
Do most of you guys clear your dalvik and cache after every flash as I have flashed all the newer versions of this kernel without ever doing that. Also is it best to flash at full charge or does that not matter? I have always just flashed at whatever charge I was at.

Also coming from t5 to the latest I notice my battery quickly drains the first 10 percent then slower on the next 10 and seems to hang in the 70s for the rest of the day. Is this happening for anyone else or is this a result of how I go about flashing?

Thanks in advance.
[Captivate Android Development] ninjuh:
Sounds all good to me. I wouldn't worry about the dalvik cache unless you're running into problems.

sent from recent
[Captivate Android Development] keitht:
Man, that drop from 100% > 97% after pulling the plug from a full charge bothers the hell out of me. I know it is a 2.2.1 cosmetic thing but still. Just venting :)
[Captivate Android Development] WickedNite:
I always clear dalvik cache before flashing any Kernel or Modem. Idk, it's now my habit to do that before anything else.
[Captivate Android Development] Aus_Azn:
This is why I don't like being able to see the exact percent.
[Captivate Android Development] sjavvaji:
hardcore...i think you have perfected the kernel at this point...idk where else u can pull battery from...can we move onto undervolting for super duper battery life?
[Captivate Android Development] mcord11758:
Just wanted to say love the kernel
[Captivate Android Development] ajm786:
Just wanted to let you know. The latest Speedmod BREAKS any functionality with any type of security program that locks apps. I tried it with all but a few. Had to switch back to Firebird. Flashed multiple ROMs, same result with them all.
[Captivate Android Development] sjavvaji:
try reenabling the logger through tweaks...i believe thats all he changed
[Captivate Android Development] ajm786:
Can anyone else confirm this? It's not that I don't believe you, it's that before I go and flash another kernel yet AGAIN, I want to be absolutely sure!
[Captivate Android Development] matt310:
I just flashed the speedmod-kernel-i897-k12q-500hz-CWM and it's really nice. Here are my questions:

Coming from re-oriented #99, my linpack scores on speedmod are 11.8-12.4 where as the re-oriented (xcaliburhand) was never below 14. Does this mean much?

Also, auto brightness is definitely lower now, which should help battery life, but perhaps at the expense of my vision.

Just wondering on my first point though - is this a slower kernel than re-oriented 99?

Thanks!
[Captivate Android Development] LimaI896:
Had to leave this kernel for an OC/UV kernel. Performance and life is much better.

This kernel would be unbeatable if OC/UV was applied. Hoping it comes in a near future. :(

Im excited, only reason I left as the psx emulator doesnt like this kernel at 1ghz. Runs perfect at 1.2. Gotta play my ff7 when I'm bored.
[Captivate Android Development] rlamontjr:
hardcore can you add hpcall support.?
[Captivate Android Development] hardcore:
Yes that's the reason. Some/most of the app lock apps depend on the debug log. If you think about it, that's quite a bad design.

Re-enabling the debug log via Tweaks will make them work again, but you lose the benefit of having the debug log disabled.

A better move would be to find an app lock app that does not depend on the debug log, or report the problem to the developer so he can change the way it works.
[Captivate Android Development] Exostenza:
Hardcore do you recommend a specific modem to pair with your kernel?
[Captivate Android Development] TRusselo:
This kernel is lightning fast! wow! and the GPS/ direction tracking is lazer accurate and fast as well..

the other thing that is fast is the battery drain. unplugged and was down 3% after sitting with the screen off for 15 min. been 8 hours now barely touched my phone today and its down to 50%. my fingers have probably been on the screen for less than a half hour. down to 50? is that normal? although i did flash 500MHz default. would that be it?
[Captivate Android Development] slifer315:
no, that's not normal, but that's also not because of the kernel. you should recalibrate your battery (there are a few guides floating around; I don't remember the specifics of the procedure) and wipe your dalvik-cache in recovery mode.
