It's because you're running a captivate rom. Speedmod is a reorientated i9000 kernel. In theory I would think that since your running an i9000 kernel/modem combo, it should be good...but I bet it's the rom.
[Captivate Android Development] trekie86:
Anyone else getting connection errors when in the market? I click retry and everything works but the error seems pretty consistent. Running K13A.
[Captivate Android Development] xreflection:
Dropping faster can be due to bad calibration. When you flash kernals a lot or not on a full battery, your phone can indicate the wrong battery level (i.e. 70% when it actually is 80% or something)
[Captivate Android Development] delugeofspam:
Heh, no.

I have never used an i9000 ROM and I still get great battery life with this kernel.
[Captivate Android Development] b0wz:
SGS tools, clear the market cache...reboot, install one up you know you have, and it will all come back, mine did:)
[Captivate Android Development] SirBrettrick:
He's referring to the lack of Bluetooth capability, not poor battery life. And he's more than likely correct.

[Captivate Android Development] Johnston212:
I don't know if this is due to the kernel, but ever since I flashed K13A last night, my phone has been vibrating constantly. It's the kind of vibrating you get when something crashes or is about to give you the force crash screen. Not sure what to do to fix it, it is kind of annoying.
[Captivate Android Development] LightningGA:
I've been running K13A all day and haven't experienced that at all. Actually I haven't had a single fc at all.

[Captivate Android Development] PuffinNugz:
k13a works great for me.
[Captivate Android Development] Johnston212:
It's not that anything is force closing, but that I am getting the buzzing vibration that the OS gives you when a fc happens. Also, my battery settings have gone wonky since I rebooted it recently. I think I'm going to reflash the kernel, then the modem, clear battery stats, and then do another clearing of dalvik. Would this work if I reboot recovery between each step or would I need to reboot the system as well?
[Captivate Android Development] geokilla:
So Perception or any other ROM based on JPY (i9000) will restore bluetooth?
[Captivate Android Development] Exostenza:
Hardcore you are like Daft Punk..... man or machine? We will never know!
[Captivate Android Development] trekie86:
Well, that seems to work. However, I didn't have to re-install an app, they all appeared in the app list but connect to market was great. Thanks.
[Captivate Android Development] marshal4him:
I am using the leaked AT&T FROYO 2.2 Rom. What ROM would you recommend?
[Captivate Android Development] diablo009:
Try the 500 one. Both are same except for 500 and 256. And as per hardcore, no battery usage difference between both.
[Captivate Android Development] hawkzq:
i can't download this file at this time can someone upload the file ？ thanks
[Captivate Android Development] cnigro1279:
If you look a few posts up, someone was nice enough to post an alternate link....

Btw..fwiw...just flashed enabled tweaks and lagfix and all seems good. Ill be watching the battery. Pocket Legends used to really cook it...curious to see how it does now. :-)

Hi guys, I uploaded the HZ=500 version to the first post.

Happy New Year!
[Captivate Android Development] diablo009:
Happy new year hardcore, and happy new year to everyone here :-)
[Captivate Android Development] hardcore:
The (R)ecommended Tweaks are for performance and/or battery life. The (O)ptional Tweaks are for additional features - you don't need to turn them on unless you need to use those features (cifs, vpn, etc.).
[Captivate Android Development] bedwa:
Question? Do you have either a github or a tarball or your source? Would love to take a look at it and maybe even help with an oc version. Been looking for a sweet kernel like this to put in my JPX red/black rom I'm trying to make.... ;)
[Captivate Android Development] hardcore:
The source patch is in the sgs thread, linked from the first post.

UPDATE: Uploaded more versions to the first post. Looks like Google Docs doesn't like too much hotlinking.
[Captivate Android Development] boodie:
Same here! AWESOME! THNX!!!
[Captivate Android Development] ngochuy:
I don't think so, the Kernel Hz is the minimum speed of the CPU when system is idle. The less speed is, the less energy the phone need.

Anyone tried JL3 and JK4 modem. Which one is the best for battery ?
[Captivate Android Development] opcow:
I assure you the CPU isn't idling at 256 hz.
[Captivate Android Development] silverslotcar:
In the words of Hardcore himself. The battery usage is the same.
[Captivate Android Development] ngochuy:
Thanks everyone. I have an issue, everything works ok but when i mount the internal SD to my PC, I see 4 removable disks. I'm using Cezar rom based on JPY. Cezar uses xcaliburinhand kernel so he has to use USB mount fix here http://xdaforums.com/showpost.php?p=9804784&postcount=5741

Hardcore said:"K12 or 2.2.1 kernel, on 2.2.1 ROM: No patch needed" so maybe the USB mount fix causes this issue (2 rremovable disks from the fix and 2 removable disks from the kernel). Before flashing K12h, I only had 2 removable drives.

@hardcore: can u please make the zip update to return the stock vold.fstab of JPY? Thank you very much.
[Captivate Android Development] hardcore:
In the link u posted, the 2.2.1 file is the stock jpy one.

It's normal to see 3 drives from the phone when u mount on your pc. Only 2 are used.
[Captivate Android Development] hardcore:
The faq has some answers.
[Captivate Android Development] ngochuy:
thank you. I'm using K12h - 500Hz. It's very good. yes, only 2 are used. How about the other one? What is it for ?
[Captivate Android Development] hardcore:
It's for backward compatibility with 2.2 roms vold config.
[Captivate Android Development] bts0uth:
After a few days with this kernel I have to say I love it. I am using the 500Hz,cold, variant on Darky's 7.7 rom. No bugs or stability issues I can find and I have been looking lol. Wouldn't mind being O/C to 1.2 but I can wait and see what Hardcore decides to add next. Big thanks for coming over to our side Hardcore. You will be getting a donation from me soon.

After being jealous for a long time when looking in the i9000 section and seeing soo many options for them it is hard to express how excited I am about having Hardcore's own speedmod kernel over here in our section :p.

We have been able to use their ROMS for a long time of course but we had no kernel options. For the longest time it was Xcal's or stick with stuff made for Captivate. Now between Xcal's, SetiroN's, glitterball's, SpeedMod, and even CogKernel we have some damn good options.
[Captivate Android Development] rootnik:
I second this. Would love to see a 1.2 version of speedmod. I'm torn between this kernel and glitterball's, though the battery life of this kernel vs any of the others listed is not even close.
[Captivate Android Development] trekie86:
I'm in love with Phoenix Rising 4.5 by Adam. It is awesome. Its an I9000 with the speedmod kernel and I haven't found one feature that doesn't work. Bluetooth, wifi, & super fast GPS. Give it a shot.
[Captivate Android Development] Scarchunk:
From you're earlier post it looks like you're running stock ji6. Any of the top custom roms from the dev forum will be night and day better. I recommend serendipity at the moment.
[Captivate Android Development] GGXtreme:
Hmm. It must be Supercurio's new Voodoo Control App background service, guess it needs a bit of tweaking ;) I'm still very happy that he implemented volume button control of the analog headphone level from within any app.
[Captivate Android Development] kennonk:
I second this setup phoenix 4.5 & speedmod are amazing.
[Captivate Android Development] zuNcHAN:
Samsung Captivate I-896

Firmware version 2.2

Baseband version I9000UGJK4

Kernel Version: 2.6.32.9

Build Number: FROYO.UXJL1

I have a question, if my Kernel Version only shows 2.6.32.9 without "hardcore@speedmod-i897-k12a-500hz#120", does that mean it's incorrectly flashed? I tried both CWM and ODIN methods. However, in CWM it seems to have everything SpeedMod has (I'm not very experienced with flashing as you may be able to tell).
[Captivate Android Development] bryman27:
You flashed correctly. Captivate based roms (Cognition) don't show the kernel version properly.

Sent from my Captivate
[Captivate Android Development] LightningGA:
I'd also suggest checking out the Phoenix 4.5/Speedmod combination.
[Captivate Android Development] Spidious:
Get rid of that version put on v4.5 Phoenix and this kernal.

100% better then that leaked version ever was !
[Captivate Android Development] stangman:
Great Kernel

Thanks for the great job on this kernel, flawless! -Especially when you use the Captivate version for the Captivate and not the I-9000 :)
[Captivate Android Development] delugeofspam:
Why does everyone think it has something to do with Captivate ROMs? You can totally get extended kernel info on Captivate ROMs, I've seen it without ever using an i9000 ROM.

I'm pretty sure it actually has something to do with Settings.apk I just haven't taken a look yet.

Posted from i897/Cognition 3.04/speedmod k13a/I9088ZNKP1 using xda app.
[Captivate Android Development] kiltedthrower:
I've never flashed a kernel before. I'm going to assume it's just like flashing a ROM?

Gonna take the recommendations and run Phoenix 4.5 with this speed mod.
[Captivate Android Development] lrs421:
Pretty much. Grab the CWM download and flash in recovery mode.
[Captivate Android Development] trekie86:
This runs great with Phoenix 4.5, you will love it. The only issue I had was the Market kept disconnecting, I ran the Market fix using SGS Tools and everything is back to normal.
[Captivate Android Development] arabcamel:
When I go to Pandora, I can't seem to lower the media volume. It stays on Maximum volume. is this an issue with Voodoo sound?
[Captivate Android Development] Aus_Azn:
You have the box checked to link digital and analog volumes. It was default in previous versions of the control app. I've hit this so often by mistake and had my ears blasted out.
[Captivate Android Development] kiltedthrower:
Okay, I just did something stupid.

My screen shows a white phone wtih a yellow triangle with a exclamation point and then a desktop computer.

What do I do?

Edit...okay, forced it into download mode. Is there anyway to get back to do another TiBu or is this just a lesson in making sure I back my phone before?
[Captivate Android Development] trekie86:
Yep, that's not good. Get it back into download mod and flash back to stock or whatever ROM you were running. If you can't get into download mode using the button combo/usb method, you will have to use a USB jig. What happened before you got the "uh-oh" display?
[Captivate Android Development] kiltedthrower:
I got it back into download mode. But odin isn't picking it up so I can't flash.
[Captivate Android Development] trekie86:
Did you have ODIN running first? Also, I'm sure you have the drivers already installed.
[Captivate Android Development] kiltedthrower:
Geez. Got Odin to recognize it...ran it. And now it's stuck on factoryfs.rfs and my screen went purple.
[Captivate Android Development] rwj5279955:
Just run it again. I got yellow screens a couple times. I reinstalled ODIN and all was well.

Sent from my molested SGH-I897
[Captivate Android Development] TonyStark R.I.P.:
Aside from your thoughts, how do you find out what kernel is running?
[Captivate Android Development] trekie86:
Shoot, someone else had the same thing with factory.rfs. I can't remember what thread. Take a look around with search and see if you can find it. They got it to work but I don't remember how.
[Captivate Android Development] Johnston212:
I still seem to be having the weird problem with random vibrations, which has only happened since K13A. I've actually gone in and disabled every setting on the phone that could have any effect on vibrations and it's still doing it. Don't know what is causing it, but I figured I would mention it and see if you all had any opinions.
[Captivate Android Development] trekie86:
So no rhyme nor reason for when the vibrate occurs? I haven't had any strange vibrations happening with 13A.
[Captivate Android Development] papilliond:
Johnston, the vibrations could mean a whole list of things. The only thing that works for me when I get that error is flash back to stock using ODIN, then flash your ROM, then once the phone is booted with the ROM and after the phone is through loading (5-10 min after screen comes on) then go back into recovery and flash the kernel again. Normally you should be able to flash kernels directly over other kernels as long as the lagfix is disabled or the lagfix is ex4, since the speedmod uses ex4. It's best to just disable your lagfix before installing another kernel. Hope that helps.
[Captivate Android Development] doreyu:
I remember that thread, I believe they just redownloaded Odin.
[Captivate Android Development] Johnston212:
I actually flashed back to k12u because the google voice bt dialer stopped working and now there are no more vibrations, but my headset isn't connecting and I can't manually reconnect in settings. All kinds of fun today, huh?
[Captivate Android Development] Johnston212:
Ok, powered down my phone to charge it briefly and bt is connecting, but Voice Dialer still won't go past startup. So I will just have to deal with this until next week, when I can begin all the fun again. Maybe I can see if I can figure out how to make Vlingo work for once.
[Captivate Android Development] majinzen:
I believe you have xcal's kernel. That's what mine says (plus build January 31, 2011) and I know I'm using xcal's.
[Captivate Android Development] Dupontrocks11:
As soon as I flashed the kernel, I began having the infamous no service problem. The only way to fix this is to reboot. This was fine on k12t, any ideas why?

Edit: Noob move, I flashed the i897 version instead of i9000 version (which is the rom i'm on) DOH!
[Captivate Android Development] Prototype159:
i9000 is for the actual i9000 phone. You need to use the i897.
[Captivate Android Development] Dupontrocks11:
Yes but when I use that I get unpatterned no service areas in part that I've been using my phone since I got it. I'll report back when it happens unless you know of a fix.
[Captivate Android Development] Prototype159:
Have you tried using a different modem?
[Captivate Android Development] Dupontrocks11:
I like the modem I'm on now, JP1. It's fast and it has great battery life paired with	speedmod. Do yoy know of any that compare to jp1?
[Captivate Android Development] WickedNite:
Do you have a link for that JP1 modem?

Sent from my Muscles using Brain Cells
[Captivate Android Development] Dupontrocks11:
Nope it just came with 7.2 ultimate tims tweak. The battery results are somewhat inconsistent, bit the best I've got on it was 50 hours with semi moderate use.

Holy crap I meant KP1!! I'm not dumb just a little tired is all :)

I can't search because I'm on the xda app, but I want to make sure I do things right. I'm running serendipity 5.5 with the jl3 modem but the modem will probably be switched. I'm just wanting to make sure I flash the right version of the kernel. Do I flash the captivate kernel or the I9000 version? I asked this in the serendipity thread but I just want to confirm. Thanks.
[Captivate Android Development] Prototype159:
The captivate version.
[Captivate Android Development] H3llstorm:
I'm very happy with Serendipity 5.5 & Speedmod k12u.
[Captivate Android Development] xreflection:
Mmm..I seem to be getting crappier battery life with K12U compared to K12S on Darky 8.1. I used to be able to go at least a day and a half. Today I barely got 20 hours. I recalibrated and everything too.
[Captivate Android Development] darkamikaze:
Has anyone done a test regarding battery life with an ext4 /system vs a regular rfs ? or any form of lagfix vs rfs using this kernel :X ?
[Captivate Android Development] tazman171:
It's a program or programs force closing in the background. No need to flash back to stock, just start un installing programs until the vibrating stops, one at a time though.

Did you restore anything with Titanium Backup? :cool:
[Captivate Android Development] cwgannon:
Use ddms (ddms.bat is the file in the Android SDK); it's sort of a GUI to adb, with a lot of other incredibly useful functions. The included logcat display makes it very simple to track down errors like this; hell, there's even a button to filter for errors.

(If you're on a newish version of speedmod, you'll have to enable the android logger from the tweaks menu in the speedmod recovery section.)
[Captivate Android Development] tazman171:
+1 Or you can logcat it of course if you know your way around adb. Good call cwgannon. :cool:
[Captivate Android Development] Johnston212:
Thanks to you both. However the voice dialer going wonko warranted a reflash, plus it gave me an extra reason to finally upgrade to 10.3. Hopefully this will fix it.

BTW, once I have finished restoring the backups, I'm going to go into CWM and flash K13A, then ZNKP1, then clear main cache, dalvik cache, and battery stats just to cover all my bases. Think I should reboot recovery between each or certain parts?
[Captivate Android Development] max_82:
I've recalibrated too but as I said before my battery is drop faster than before I flash this kernel on my phone. Is it because the compatibility with ROM or the tweaks? I enable the first 4 of tweaks from recovery. Does anyone can explain it?
[Captivate Android Development] Johnston212:
Did you clear main cache and Dalvik cache in CWM? I've been told these can attribute to battery drain. Also clear the battery stats can help and do you have HSPA+ on or off?
[Captivate Android Development] max_82:
I've cleared main cache and dalvik cache also battery stat. HSPA off, I use EDGE.
[Captivate Android Development] delugeofspam:
Hey hardcore, I'm paying the bounty on this: http://xdaforums.com/showthread.php?t=916233

Xcaliburinhand worked out a way to get USB Audio working for the Samsung Car Dock. I'd like to see it incorporated into your kernel soon, if you can find the time.

Someone in the original thread mentioned that they don't think the whole signal is getting out the door. Maybe since you've been tweaking sound channels you can put your finger on what the problem is (or at least tell us there isn't one, lol).

As usual, your hard work is appreciated.
[Captivate Android Development] arabcamel:
Thank you for the reply. I think it was fixed on it's own with an update to the Voodoo app. It's good it was fixed automatically because i'm not sure which box you are referring to. :-)

I disabled the darkest auto brightness and I don't notice it being any brighter. I have auto brightness on. Is there something I'm missing?
[Captivate Android Development] Johnston212:
Ok, so last night I re-flashed everything. I'm now on Perception 10.3, with K13A and ZNKP1. Vibration problem seems fixed, however bt voice dialer is still not working. Is it possible to uninstall and reinstall the google voice dialer?
[Captivate Android Development] sinichi21:

[Captivate Android Development] kennonk:
I am running K12t with Phoenix 4.5 and it looks like logging and logcat is broken? I was wondering if anyone knows why? I am completely missing the /sys/kernel/logger folders and all the logcat apps just sit there with a blank screen while trying to load the logs. I tried searching this thread but search appears to be offline tonight. Any ideas?
[Captivate Android Development] smokestack76:
I beleive you can enable logging in recovery menu.
[Captivate Android Development] hardcore:
Thanks for letting me know. Will have a look at it.
[Captivate Android Development] hardcore:
It is a new feature of the kernel: dmesg and logcat / android debug log are disabled by default. This speeds up the phone and saves some battery.

If you need logcat for development, you can turn it on from the TWEAKS in the Recovery menu.
[Captivate Android Development] hardcore:
That setting prevents auto brightness from going to the "darkness mode" minimum brightness. You can see the difference if you switch to minimum manual brightness - it will be darker than the minimum auto brightness.
[Captivate Android Development] kennonk:
Yes that was it. I guess I didn't enable it when I originally did all the tweaks because of the big (NOT RECOMMENDED) next to it. But it is working now. Thanks.
[Captivate Android Development] clemmie:
Overclocking

Is there any benefit to using an app like Overclockwidget to control voltage with SpeedMod? I know there are 2 versions for 250 and 500, If I push to 800 with an app like this will I see a noticeable difference in performance? Quadrant Score doesn't suggest that it will, but I'm not convinced about the accuracy of numbers like that anyway. Any thoughts?

Just wondering how I should install the the lagfix? I know I have to go into recovery and then the lagfix options, but what options do I enable?

[Captivate Android Development] backdownup:
Hate to break it to you hardcore, but your kernel, and your kernel only, drains my battery at 3% per 30 minutes with the phone laid on my desk.

I don't know why. I tried many, many different setups and ideas. Did a back and forth kernel flash on stock 2.2 froyo. In 30 min after unplugging from charger, I am at 97%... charged to full, flashed stock kernel, removed from charger, checked battery in 30 min, 100%.

It's not a battery display error. I've bump charged, cleared delvick and batt stats, and all the drain and charge ideas.

It's this kernel.

I896 - Rogers Captivate. Froyo 2.2.
[Captivate Android Development] hardcore:
This is not a battery drain problem. It's a change in behavior of the battery meter in 2.2.1 kernels. (SpeedMod kernel is built from 2.2.1 kernel sources.)

The battery will not always be charged to 100% if it is nearly full (e.g. 97%) - this is to preserve the battery lifespan. Lithium batteries die faster if they are continuously charged to 100% and kept there.
