Hardcore, if you saw with the new Firebird kernel they're offering a version without BLN that people seem to be stating is helping reduce battery use even more. Any chance of making a version of Speedmod without BLN?
[Captivate Android Development] mcord11758:
Just disable bln in recovery

Is it even possible for	a feature that's turned off, at boot, by default, to eat power?

Posted from i897/Cognition 3.02/speedmod k12o/I9088ZNKP1 using xda app.
[Captivate Android Development] beerbaronstatic:
I'm asking people who are making the battery life claims if they had been using BLN. I keep mine disabled, but I was just curious
[Captivate Android Development] silverslotcar:
I've heard from many devs on this forum that BLN has a very minuscule affect on battery. Hell, some roms are even including "Keep the Lights On" now which keeps the backlights lit the whole time the screen is on. They barely use any battery, the difference wouldn't be much at all....
[Captivate Android Development] hardcore:
As others have mentioned, BLN is optional and if you do not turn it on from Recovery, it is completely disabled.
[Captivate Android Development] beerbaronstatic:
Well, BLN stuff aside, how is K12P running for people?
[Captivate Android Development] LimaI896:
Only made one phone call, I can't hear the other person great. They said they heard me well but a minor slight echo. I am going to call my self from his phone soon to see what he is talking about. Might flash back to K12O to compare.

Hey hardcore I dont know if I'm deaf(very possible lol) but is it possible to make the hearing on my end even louder? Or should I just try another modem as that may be the reason. These phones now a days are useless in slightly noisy areas.

[Captivate Android Development] JeffreyF:
So I've searched high and low and I'm pretty sure I overlooked something, but how exactly do I flash a new kernel on top of the one I'm running now? I want to upgrade from K12M to K12O and want to cover my bases before I start.

So far as I can tell I can just download SGS Kernel Flasher and flash the CWM version I downloaded. Is that all I need to do?

Thanks in advance.
[Captivate Android Development] jhernand1102:
Yes just point the SGS kernel flasher to the CWM file and flash away
[Captivate Android Development] WickedNite:
I see. It's like beta testing or something like that.
[Captivate Android Development] xreflection:
This is a really stupid question, but I'm slightly confused about which version I'm supposed to flash.

I'm currently running Darky & ytt3r's ROM v8.1 for the Captivate. Do I download the captivate version of K12O or the I9000 version? I ask this because the ROM is based on an I9000 ROM, so I'm not completely clear on the compatibility considerations.
[Captivate Android Development] jhernand1102:
Always the Captivate version. The ROM version does not matter
[Captivate Android Development] xreflection:
Thanks. I just wanted to make sure I didn't screw up compatibility, lol.
[Captivate Android Development] laz0r:
This kernel does not support using voltage control to UV correct? Would there even be a noticeable benefit to undervolting further with this kernel anyways?

[Captivate Android Development] xreflection:
What setting should I set to enable the lagfix? I'm curious as to see what kind of benefit it gives compared to it off, since speedmod is already fast without it.
[Captivate Android Development] hardcore:
There is only one setting to choose from now, and that is the recommended one.
[Captivate Android Development] Lancez:
hey chief,

anyway to fix the "silence the incoming call by pressing on volum botton"? thanks
[Captivate Android Development] silverslotcar:
Hey im currently running andromeda with your kernel k12p t1. When I boot into recovery, after I navigate with the volume buttons, a message pops up and says "back button is now disabled" and the back option disappears and when i click back on my phone its works as a select now. The only way to exit then is to reset or do a battery pull. Never had the issue before but I need a working recovery to do lots of things.

[Captivate Android Development] Exostenza:
Hardcore I was wondering if you couldn't explain why my phone will never charge to 100 percent? I have the P version on and it rocks, I love your kernel ans your work very much and just wanted to understand why this one flaw persists. Thanks for all the hard word, pun intended!
[Captivate Android Development] Gurgs:
Holding volume for one second also silences ringer...at least on serendipity

it does...
[Captivate Android Development] silverslotcar:
The not charging to full 100 percent is a known issue with 2.2.1 roms. Sometimes they do and sometimes they don't.
[Captivate Android Development] rootnik:
This happened to me before with an earlier release. I never could figure it out, but it went away with the next update.

Nobody else reported it so I thought it was just me. Maybe just try flashing the kernel again (or better yet, update to the newer version).
[Captivate Android Development] arabcamel:
I was able to do this with my stock rom on captivate which was 2.1
[Captivate Android Development] silverslotcar:
I didn't think there was a difference between K12P T1 and K12P?? I just have the test version he posted. I may just have to Odin to stock and start from scratch, bcuz I need a working recovery.
[Captivate Android Development] silverslotcar:
Yea, it was a 2.1 feature too, but who uses 2.1 roms nowadays?? Lol Im just sayin'
[Captivate Android Development] rootnik:
It may have just been a bad flash man. I'd try just reflashing, if that doesn't work flash the odin version of the kernel, if all of that doesn't work try starting from scratch.

[Captivate Android Development] ninjuh:
When I flashed the newest version of this kernel from firebird my phone went through a big backup process & changed from ext4 to something else. Is this normal? Never had it do that before when flashing kernels
[Captivate Android Development] rootnik:
Configs must have been slightly different. No big deal, just change it back to ext4.
[Captivate Android Development] ninjuh:
Go to cwm lagfix and enable ext4? Also can I delete the log files and cwm backup folder flashing this kernel created?
[Captivate Android Development] rootnik:
Yes.

I'll let somebody else answer the log/backup folder question. I don't see the problem with it, but have never done it personally.
[Captivate Android Development] silverslotcar:
Well you can delete your backup but then you have no backup!! LOL But yes, boot into recovery and go to advanced something and find "lagfix options" then enable a=e4 EXT 4 lagfix.
[Captivate Android Development] ninjuh:
Thanks for the help guys. I never have that folder on my root anyways so I don't think its a problem deleting it
[Captivate Android Development] eep2378:


I've had this happen before. I think this is a feature built into cmw. I inadvertently disabled the back button before and I think it was from navigating to quickly with the volume buttons. I was sweating it at first but what worked for me was to press the volume up and volume down buttons together at the same time. For me that toggled back button on/off. Don't ask me how I figured that out. I'm not even sure if this is fact but it worked for me
[Captivate Android Development] silverslotcar:
You were right about it being from pushing the buttons too fast. I did my navigation very slowly and never lost the back button ability. I can't attest for the volume buttons working though bcuz I didn' try to move the buttons too fast. Haha and I had no issues the first time trying it.
[Captivate Android Development] keller.jeff:
I just installed K12P, and now my laptop won't see my phone. I get a USB ding dong, but I can't see the drives and droid explorer don't see it.
[Captivate Android Development] ubikwitus:
Have you tried reinstalling the drivers on your laptop?
[Captivate Android Development] ubikwitus:
By flashing with SGS, will I need to reinstall all my apps afterward? I've got a recent backup of everything with TiB, but I want to see if i'll need to do a full backup before i flash this with SGS.

Thanks!
[Captivate Android Development] tartarspoon:
You will not have to reinstall any apps.
[Captivate Android Development] LimaI896:
Flashed K12P and changed my modem to the JL3. Phone call quality was great.

Guys that are having problems flashing make sure you use the right file for the way you are flashing. I always use CWM and obviously flash the CWM file with out issues. I do this all on my phone, no need for a computer. First time I ever flashed was a CWM file and used SGS kernel and it messed up my phone. Just sayin in case some were confused. ;)
[Captivate Android Development] bobola:
I flashed last this with stock rom 2.2

Have terrible battery drain.

Gone from 100-> 46% when I woke up in the morning.

So I decided to flash the modem too.

Flashed i9000m JK4 modem.

Battery seems to be a BIT better.

But still not as well as before..

Would it be better if I flash to a non stock rom?

Thanks
[Captivate Android Development] LimaI896:
Flash serendipitys rom, you'll love it with this kernel.
[Captivate Android Development] WickedNite:
You could try JL2 also, that helps me get a better battery life.
[Captivate Android Development] bobola:
Doing this right now as we speak.

I'm using rogers too.

Do you recommand flashing to another modem too?
[Captivate Android Development] eep2378:
After flashing the "P" kernel, I think the auto brightness setting actually looks a lot better. Thanks, hardcore. I'll report back on battery life.
[Captivate Android Development] LimaI896:

You may need to enter your apn settings as I always do with this rom.

Everything working fine battery is very good now .. a bit over 1~2% each hour without use!!

I tried the Jl3 too, but it put me on "Roaming"

And I dont use data at all.

However wifi seems to eat the battery much more than before.

And also it has this problem where it doesnt load a login page when connecting to wifi.

(ie connecting to the school wifi require you to login with student numbers, usually when I open the browser it changes to the login screen. but now it just load my homepage)
[Captivate Android Development] xreflection:
Damnit, bricked my phone when i flashed with "P". Tried flashing back to O, no dice. Reflashing with odin atm...

Now I'm afraid to flash with p, lest I have to go through with all that reflashing and stuff. I'll wait till next release.
[Captivate Android Development] LimaI896:
I never use wifi so I would of never noticed that problem ahaha. To be honest I don't even know when I'm roaming or what it is exactly but I believe there is an option to never roam. As long as my phone bill is the same I'm happy.

Only modems I tried were the jk4 and jl3. Call volume and quality were noticably different. Data got a little slower though.

Need Help Please

I have speedmod N installed no problem through recovery mode.

I downloaded latest K12P and placed it on both my internal and external SD cards (just to be sure). But when I use recovery mode and try to install the zip file, it does not see the K12P file for some reason (but still sees the N one on there along with all the other files I have on there like ROMS etc)..

Also, when I try to use SGS kernel flasher with the CWM or ZIP file, it does not work.

And lastly, when I try to use CWM (ROM Manager), it also gives me an error that says the following:

E: failed to verify whole-file signature

E: signature verification failed

The thing is, why doesn't it see the file in recovery like it did for N??

Any help is much appreciated, thanks :)
[Captivate Android Development] LimaI896:
Id personally wouldn't bother with sgs kernel. I would reinstall rom managers cwm and redownload k12p cwm file and try to flash it again via cwm. This way I never had an issue.

Check the first page, I made a guide to work around this

Thanks I followed the instructions. But the problem is that when I boot into recovery, I still do not see the K12P file there (even though I know it's there since I see it when I use root explorer). All my other files are there except this one, how frustrating LOL :confused:

DISREGARD

Got it working, I had copied the wrong file, so now that the signature fix is done, worked like a charm :-)

hardcore,

I was wondering if u could make a no bln kernel or tell me how to remove it from the kernel. I see that some people had much worse battery when the kernel supported it even with it disabled. Im not sure how easy it is to remove it completely, but I can do it if u give me a little help. Other than that, I haven't touched another kernel since this one was made available. Thanks!

https://github.com/project-voodoo/linux_gt-i9000/commit/04c0c6e20b7a0c0b29868cbc15a685c26405e9e4
[Captivate Android Development] sjavvaji:
how is that DAC oversampling mode working out?
[Captivate Android Development] supercurio:
It's a 100% hardware parameter, happening in the sound codec only.

The default mode (64x OSR, low power) allows to use lower clock generator frequencies: this is what makes the most difference in power usage.

However, in Samsung driver, the "low power" 64x oversampling is used with the highest clock speed setup, which means it's probably a better option to use the "performance mode", that provides a better SNR and lower distortion levels, and filter better high frequency > 20KHz harmonics.

In the v2 driver, OSR128 is disabled by default - which is a conservative choice.

It may become the default in the next version.

I will publish some measurements later, showing graphically the difference in frequency response between both.
