I've been running -.75/-.50 for days now with 100% stability on everything I throw at it. I'm going to try -1.0/-.75 next.
[Captivate Android Development] vw671:
I ran both ext4 and JFS and honestly couldn't really tell the diff between the two performance wise.
[Captivate Android Development] darkamikaze:
I thought the reason we ran JFS is because it's better for battery and easy on CPU or something
[Captivate Android Development] LinuxNewb:
It's weird because it just seems random for the people who are having this issue. I'm on an I9000 rom as well so I don't know why I'm having this issue.

I've been playing around with modems and settings so pretty soon I'll be seeing if I can narrow down which modem is giving problems with the 850 band.

Love the kernel btw :P
[Captivate Android Development] bts0uth:
Any i9000 modem (JPP and JPM are the two most common) will give you 850band problems if you don't flash it the correct way.

If you just simply flash JPP or JPM over whatever you are running your 850band will not work, period.

You have to follow all the steps that are listed in the first post of this thread and in a lot of others in order for it to actually work and for your phone to connect to the 850 band.

At first I figured people were just being dumb and all those steps aren't needed to get it working but for whatever reason they are. I know because I have done it at least three times lol.

Well just updated to v1.3 . All I have to say is awesome and oc/uv is now sticking through reboot . I have been running -100 on 100 - 800 and -75 on 1000 - 1200 with no problems or fc's . I just tried -125 and -100 and thought it was all good till I tried to post this and boom locked up :) . But I'm loving cog v2.3b3 , v1.3 kernel and jpp modem . Awesome battery life and runs the best my phone has ever ran. Thanks again SetiroN :)

UV settings

Settings for undervolt that worked for me. i896 captivate.. not as low as unhelpful's kernel but similar

100 mhz -100mV

200 mhz -100mV

400 mhz - 100mV

800 mhz -150mV

1000 mhz - 175 mV

1200 mhz - 150mV

Just ran quadrant a couple of times to see if it would lock up. So far it's working. However. Stability was not evaluated enough so your mileage may vary.
[Captivate Android Development] arffer:
I'm confused, this seems to be the opposite of what is commonly seen. The higher the frequency, the lower the voltage? All the configs I've seen, you can run a lower voltage at the lower frequencies. But as frequencies rise, so are the needed voltages.

What happened with my Data ?

Guys.

I was running perfectly on 1.2, with H connected all the time. Now after i updated to 1.3, the data icon jumps between 3g and H, but there are no connection at all. No data. I just flashed via CWM and now this is happening with my captivate. Any ideas??
[Captivate Android Development] PuffinNugz:
Is this the case even if you are just upgrading from 1.2 to 1.3? I already had it enable previously. I don't want to set 850 as the only band to use, do i? If I set it to automatic, I lose the 850 band, but if i leave it as the only band, it seems to stay connected.
[Captivate Android Development] bts0uth:
If you have it working already then you are fine. Updating the kernel doesn't change anything to do with the modem.
[Captivate Android Development] MarlowXim:
Reference stock voltages

1000000 hz 1275 mV

800000 hz 1200 mV

400000 hz 1050 mV

200000 hz 950 mV

100000 hz 950 mV

You are subtracting from the default voltages. If you are confused I suggest you leave them at default.
[Captivate Android Development] SetiroN:
@thecellx - that behavior is perfectly normal, despite common sense the H icon shows intensive data traffic instead of HS(D/U)PA conncectivity. It surprises me how you previously used to have H all the time.

v1.3.1 OUT

- included ext4 patches from http://www2.kernel.org/pub/linux/kernel/people/tytso/ext4-patches/

- additional FS optimization script to remount partitions with -noatime included in the I/O Scheduler script
[Captivate Android Development] bts0uth:
Your last two posts have me confused as well.

Are you saying for 1200 you dragged the slider in voltage control app to -150?
[Captivate Android Development] l7777:
Don't use the automatic option. Select GSM all, then go to the combi bands menu and select WCDMA 850. Confirm that you can connect to the WCDMA 850 band from the basic settings menu and note signal strength. Then go enable the other WCDMA bands in the combi bands menu and see if it then changes to 1900. My phone also likes to stay on the 1900 mhz band even if 850 is available. It only seems to switch to 850 when the 1900 signal gets really bad, -110 to -121. I am almost ready to force it to stay on 850 unless I intervene. It is worth noting that my colleague's captivate with stock rom and stock radio behaves exactly the same as mine and gets the same signal strength.
[Captivate Android Development] arffer:
First, make sure that 850 (both gsm and wcdma) are enabled in the combi setting. The selected choices in the combi setting are what get used when in 'automatic'. So, if you can get 850 in manual, but not in automatic, then 850 may not be enabled in the combi screen.

Second, if 850 is enabled in combi, but you only get 1900 when in automatic, then 1900 may simply be a lot stronger where you are.

I've been getting kernel panics, FC's and freezes on 1.3 and 1.3.1 running this ROM. Reflashed the ROM and cleared everything then installed 1.3.1 and still had issues. Booted to recovery and installed 1.2 and it's stable so far.
[Captivate Android Development] s44:
Is there a reason folks aren't editing the framework to make haptic-enabled Captivate versions of these i9000 ROMs?
[Captivate Android Development] thecellx:
Same

Same as you. on 1.3 my phone is weird. Its rebooting itself, and freezing.
[Captivate Android Development] slifer315:
I just flashed the JI6 modem from the Cognition 8.1 rom, and am still having the same problems. :/
[Captivate Android Development] smokestack76:
Did you log it at all? Havent installed but was just getting ready when u posted lol
[Captivate Android Development] peachpuff:
My wifi started acting up with the 1.3.x kernels, couldn't connect majority of the time, went back to 1.2 kernel and all is fine... weird.
[Captivate Android Development] bts0uth:
I think this is a pretty common issue but not certain,

I flashed JI6 modem over my captivate rom but im using this kernel.

People are saying my voice sounds muffled and it has a sort of staticy sound to it.

Is this what has been reported by people using a captivate modem on a i9000 kernel (like this one?)
[Captivate Android Development] opcow:
No, I had been futzing around with various swype versions trying to find one that would work on my ROM and I was concerned that maybe I had accidentally deleted a lib I didn't intend to, so I wiped everything and started over. As soon as I noticed the problems remained, I rolled back to 1.2 to see if that fixed things.
[Captivate Android Development] mcbooth:
I had this exact same issue. Flashed back to JPP modem and have clear voice and no random reboots anymore.
[Captivate Android Development] thecellx:
Weird issues on 1.3

Besides my already reported 3g to H constant switches, that im sure they were not on 1.2, mine have a little new issue. Everytime i unplug the battery charger... the phone reboots... for the ones that had already reaplied 1.2, not i need to reset UV ... or what is the right path to downgrade?

Thank you.
[Captivate Android Development] Rhiannon224:
I am running this kernel with Tayutama's I9000 reoriented Froyo v1.0.2 and I have had no soft reboots of any kind. I haven't had any signal loss and drove a bit today, it switched between hsupa and 3g without a problem. I am in an area where 850 is not available but I have checked and it is enabled. I have all the combi bands selected when I enter *#2263# into the keypad. I did a frash install from JF6, flashed the JG8 modem with Odin and master cleared. I flashed Tayutama's ROM first and after that booted up I booted into recovery and flashed the kernel, then I let it boot up, went into recovery again and then installed the lagfix, I choose voodoo like, yesterday I ran into trouble flashing over Excaliburin's Voodoo kernel and trying to install the jfs lagfix. No FC's either! It is snappy and smooth, I have left the OC alone, whatever the default is works fine, I don't know enough about it to mess with it. Last time I messed with undervolting I had the sleeping death on one of the Cognition builds. So far so good. Thanks for the great work donation is coming.
[Captivate Android Development] vinunleaded182:
I know I will get a beating for this but Im willing to take the risk.

Can anyone tell me if the OC/UV feature comes Overclocked and Undervolted? If i want to leave those settings as the stock should I leave the settings alone or change it to stock settings?
[Captivate Android Development] thecellx:
Could be my undervolt settings..

Maybe my issues on 1.3.x could be my UV settings:

50 from 100 to 800

25 from 1000 to 1200

I used that on 1.2 without issues.
[Captivate Android Development] SetiroN:
By default, the phone will just be overclocked. You can undervolt, as explained in the first post, using Xan's application. With the same app you have an option to disable overclocking as well by maxing the frequency out at 1GHz.

Please try out v1.3.2 :)

v1.3.2 OUT

- stability fixes
[Captivate Android Development] smokestack76:
Sheeeshh. Another one already! I cant keep up lol
[Captivate Android Development] ThisWasATriumph:
This thing is FAST. just scored 16.86 MFlops Linpack with Tayutama's ROM.

Props for putting all this together man. I'm pretty sure they don't even have all this in one kernel in the i9000 forum :P

My poor phone

I have Molecule Rom (basically cog cde beta 5) with, c3polol's battery mod, UCJJ4 modem, and now this kernel. It hasnt blown up yet.

*shrugs*
[Captivate Android Development] bts0uth:
Well to save yourself some time don't try either overkill lagfix because the phone never boots up. Gets to Galaxy S screen then just goes black.

I just reverted back to no lagfix so hopefully the phone will start up and I will try either all JFS or all ext 4.

Anyone know if there is a difference? ext4 or JFS?
[Captivate Android Development] TheTodFather:
jfs is the best in my optinon it is designed for flash memory and it is a battery sipper. Slighly slower then ext 4. I would go jfs if i where you

would cwm work in jfs? hmmmmm

we need to start a thread that has all the pros and cons of all the options for lagfix
[Captivate Android Development] darkamikaze:
I would love to have that pros and cons list.. because I'm not really familiar with the differences X_x
[Captivate Android Development] TheTodFather:
i saw it on sztupys thread... in the i9000 maybe i can find it for ya
[Captivate Android Development] crazililazn:
quick question, flashing this kernel will flash the JPM modem right? Cuz currently I am using JPP and I just want to make sure.
[Captivate Android Development] ThisWasATriumph:
Nope only the kernel. I am using JPP as well and it stayed.

Which brings me to another point, the JPP modem is way better than JPM. I was getting 50% time without signal before I flashed JPP.
[Captivate Android Development] TheTodFather:
usually flashing kernel will not flash your modem. Its the rom that does that.
[Captivate Android Development] glitterballs:
Nope. Kernel and modem are two different files. Modem stays the same.
[Captivate Android Development] crazililazn:
kk, thanks. Phone is currently 100% charged and i might give it a go :D
[Captivate Android Development] airbillion:
Does this kernel touch the blm, or does it have the 3 button fix for the captivate built in. I have a v1008 captivate and it is brickable if the 3 button fix is removed. I want to try this but I am hesitant if I will lose the 3 button combo.
[Captivate Android Development] TheTodFather:
stay away this has dragons! I pretty sure this dosnt have the 3 button fix. I would not play with it if i where you... not for now at least.
[Captivate Android Development] airbillion:
Damn it! I was hoping to try it, but I already bricked 1 phone without the fix and I dont want that to happen again. Hopefully someone can integrate it!
[Captivate Android Development] opcow:
It's a kernel. The sbl isn't touched so you won't lose the button combos.
[Captivate Android Development] tytdfn:
That was THE most annoying bug i have ever encountered when using the captivate. Hands Down

EDIT: OP is offline right now but who wants me to whip up an unofficial update.zip of both versions with jpp modem?
[Captivate Android Development] cropythy:
So an update.zip with kernel and JPP modem? I would love that if I am reading that right. Also would that be cwm flashable then? I am not a fan of odin...I prefer to do it all from phone if it can be helped.
[Captivate Android Development] tytdfn:
Yes thats correct. would you happen to have the jpp modem handy? I have to download the whole jpp rom to extract the modem and its taking a while
[Captivate Android Development] jhnstn00:
Lets see who's phone combusts first due to sheer speed and raw power unleashed.......Just kidding.. Knock on wood. ;)
[Captivate Android Development] LinuxNewb:
I have read the post many times and did it that exact way when I did my JPA setup and when i did my JPM setup. I made sure to repartition each time I went to the 2.1 build and had my 512 pit file.

But if we can find a common link or recreate the steps to prevent it, then we should have a better "fix."
[Captivate Android Development] shaolin95:
And to confirm to go from 1.3.1 to 1.3.2 there is no need to disable the special tweaks...just reset UV to stock and flash away, right?
[Captivate Android Development] Kizzmiazz:
Just flashed v1.3.2 first time I have flashed and had my first fc lol no biggie, I rebooted in to cwr and wiped dalvik cache and fix permissions and all good again ( lithium music player was the fc ) I don't know what happened but the phone vibrated and then fc, I opened it again and said there was no music. All good again though, so far ;)

I can not keep up with the releases of this kernel lol I have skipped a few since there coming out so fast. I'm flash addict though so keep em coming lol

is there a way to manually disable OC?

[Captivate Android Development] Kizzmiazz:
Only having one problem so far, not huge and really don't know if the kernel, rom or something else I changed is causing it. When I hit the power button to turn the screen off if I hit it right away to turn back on to get to the lock screen it kinda trips out lol shuts off again and takes a few trys to get it on but if hit power button and wait a few seconds (5 or 10 sec ) it has no problems at all. Like I said not that huge just wondering if someone else might be seeing this.

YEEEES!!! This is the greatest thing since sliced bread! Are all the lag fixes already applied or is there something I need to do? Thank you sooo much, team that made this happen!! :D
[Captivate Android Development] WickedStyx:
I'm guessing the problem is if you flash Cognition rom it flashes the captivate modem and undoes the work you do by flashing the JG8 modem. So you have to start all over again and make sure you change the modem in the Cognition rom update zip to JPP before flashing it.
[Captivate Android Development] bts0uth:
Same thing has been happening to me lol
[Captivate Android Development] WickedStyx:
Undervolted too much?
[Captivate Android Development] vw671:
Yep, seeing this also with 1.3.2 but not with the older ones.
[Captivate Android Development] shaolin95:
If you forget to reset UV before flashing 1.3.2 , can I reset it after flashing then flash again or is it too late?

[Captivate Android Development] MarlowXim:
The latest problem people are experiencing is "wake up lag" this was present in many compiled kernels before, since we do not know all of samsung settings in compiling there stock kernel.

Unhelpful posted a toolchain that seems to fix this problem. I know that setiron is using the sorcery g++ compiler.

Setiron here's the post related to it xdaforums.com/showthread.php?t=761923

However I don't know if the optimization flags you used with g++ may work

Also I suggest people use search more often. Most of the questions have been answered before you need to look.
[Captivate Android Development] pillz424:
What do you have set cpu on conservative? Im wondering because with 1.3.2 we have more control for undervolt on the lower freqs, and when the screen sleeps it jumps down too 100 mhz, so it glitches. Im gonna try setting it for performance and see if it still does it, or turn up the uv at the lower freqs

EDIT: nope, has nothing to do with it I guess. Also didn't see that post right above. Ill shut up now.

Also, headset doesn't work? The button doesn't stop music, there's no sound in calls, is this an i9000 kernel issue? Worked in CogKernel
[Captivate Android Development] lpsi2000:
I got the same new config with 1.3.2 and thanks to you guys I decided to pull the battery out, get back to recovery mode, then flash back 1.2. On the next reboot all seems fine, no new config prompt, and my data and apps were intact.

I think we still have weird stuff going on with 1.3.2 but it was not as immediate as 1.3 or 1.3.1. I was running 1.3.2 pretty much as soon as it was released until just now.
[Captivate Android Development] dayv:
This was the way I did it

1. Flashed odin 3 one click to stock eclair

2. Put clockworkmod update.zip, cog 2.3b3 cwm zip, jg8 modem cwm zip, and setiron kernel w/jpp modem cwm zip on my phone

3. Rebooted into recovery and reinstalled packages to get to cwm recovery

4. Cleared davlick cache, user cache, and did factory reset

5. Cwm flashed cog 2.3b3

6. rebooted the phone opened my files app navigated to voodoo folder and created a " disable-lagfix " sub folder and then rebooted the phone to disable the voodoo lagfix.

7. Rebooted again to recovery and reinstalled packages to get to cwm recovery

8. Flashed the jg8 modem cwm zip I had

9. Rebooted the phone entered *#0011# into dialer and made sure I had a wcdma850 band data connection

10. Rebooted again into cwm recovery and flashed setiron kernel w/ jpp modem cwm zip

11. Rebooted the phone and rechecked *#0011# to make sure I still had wcdma850 band data connected

12. At this point I flashed nixxed stock tap lock screen mod for cog

13. Last I went back into cwm and installed the advanced jfs lagfix

Note: I got the jg8 modem cwm zip from mikeymike01's doc rom thread.
