just flashed cognition rom today after i got stuck in boot screen while flashing a modem and have to say its awsome. Its the first rom i flashed...

is it possible to add support for voltage control?

i've also notice that battery usage stats in settings resets itself after a reboot. is this normal? i had this problem but worst before using cognition, the stats would reset but while the phone was in standby mode. also with cognition it seems to not decrease battery life as much as before. does this mean i have to recalibrate the battery after every reboot to get the best possible battery life?

thanks for the great rom!!!

Curious...

Hey DG,

Great ROM, have loved every version of Cognition I've flashed so far.

I was wondering if there was a reason you left the gingerbread keyboard out of the 3.0x versions? The Samsung keyboard works well enough but I loved the gingerbread one in 2.3b8.

Is there a possibility it might get added in later versions or did it just not work/you didn't like it?

Keep up the good work!

anyone else have wifi problems with cog 3.03?
[Captivate Android Development] whiteguypl:
Does anyone know or even roughly know what stops us from using the portrait mode wallpaper mode that is available in perception roms gallery3d.apk? How hard/easy it would be to make available? I know the apk works with cog and you can even select the portrait mode but becomes greatly distorted.
[Captivate Android Development] tboogie88:
just flashed 3.02.

all is great except my 3g signal seems to be weaker.

actually i havent seen my 3g since i flashed cognition.

is there a fix for this? or another thread i can read?
[Captivate Android Development] hamburgertrain:
Yeah 3.03 is a wifi killer.

[Captivate Android Development] ratflinger:
Did you restore any system data? My 3g has never been effected by any of the cog roms
[Captivate Android Development] paracutin:
We are not talking about stock cog. Cog contains a custom kernel and modem when compared the the factory setup this user came from. At least that is how I interpreted his question.

This is his original post.

Successfully installed my first custom ROM. Love It!

Thank you for the work you did on this. I love this phone even more now.

Couple questions.

Do I still need to install a custom kernel or modem?

I'm pretty happy with the stock Cognition ROM just like it is if its not necessary.

If I do decide to install a kernel or modem would I have to start all over with the ROM installation?

Is there a order of installation involved?

Thank you once again for making the Captivate an even better phone with your ROM.

After few days on 3.02:

I have to say this is definitely the smoothest experience so far.

It even stays smooth with all 8 windows opened in the browser... awesome!

In comparison to v2.3b8:

Minor issue:

English (UK) locale is missing. I was searching a lot on XDA but can't find a download, anyone!? The american spaces in the numbers make no sense over here!

Major issue:

No charging death (never had it on any rom) BUT phone switching off randomly if battery below 50%.

I had this on few roms before if battery was below 30%, but this time it happens way too often and too early.

I think the issue is fixed with HZ=500, but I need BT calling (so Firebird kernel not an option) and the Speedmodkernel was a huge disappointment on v2.3b8.
[Captivate Android Development] qwertyaas:
Question, how do I go about updating from 3.02 to 3.03?

Same method as a normal flash but instead of flashing to stock, just flash from recovery from 3.02 (i still need to backup and restore correct?)?

i know ppl are getting amazing battery from cog, but mine seems to be really really terible. from when i disconnected at 100% this morning at 7am, it drained to 81% within the hour when i was playing radio over wifi.... ok thats understandable. when i got to work at 8:30 am, it was down 73% — thats only with a bit of tinkering with settings. Afterwards, I just left it on my desk. It's 10:14 now and my battery completely drained to 41%.... no wifi nothing running on background, except my clock widget and 3g watchdog.

This is soooo weird. I dont want to switch to any other rom since this is the best I've had so far (themed roms are largely incosistent), with everything working as it should.

i havent changed kernels or modems. What could it possible be? It tells me that 89% of what's draining my batt is the screen.....

...weird.

Launcher pro is nice but I prefer to stick to stock android. If Somebody wants to install launcher pro they can do that themself.

Did everyone else who's having issues with wifi in 3.03 use the update .zip? Perhaps the full install is unaffected?

Wifi dchpcd Downgrade & back to Launcher2 didn't work

Same wifi issue here - used the 3.02 --> 3.03 update and lost all wifi.

Created a downgrade zip file ( extracted dhcpcd & Launcher2 from 3.02 zip) and still the same - cleared cache - still no go... shame because 3.02 was working great...

( I hate being an early adopter !) :(
[Captivate Android Development] gk527:
I figured it had something to do with the dhcpcd file that was removed and then replaced with the one in the updated zip file. So, I pulled down the full version of 3.02, pulled out the dhcpcd file from there and copied it over to my Captivate using Droid Explorer, but that didn't work.

I then replaced the dhcpcd file in the updated zip with the one from the full 3.02 zip, and then reapplied the update 3.03 from CWM. That didn't work either.
[Captivate Android Development] m37h:
Have to say that you're wrong, he said : "... I'm pretty happy with the stock Cognition ROM just like it is if its not necessary..."

And you originally said: "By flashing Cog you did install a custom kernel (Firebird) and modem (JL1)..."

And I believe that's wrong, like the other poster said I think it's based on Rogers' 2.2 injected with Voodoo + DG's tweaks.
[Captivate Android Development] Aphex13:
^I just restored a nandroid backup I had of 3.02, and all is well again... Wonder what the problem is?
[Captivate Android Development] pigrew:
This method worked for me. I extracted the dhcpcd from the 3.0.2 archive (file also attached to this message), sent it to my phone via bluetooth, then ran the following commands (via adb shell):

su

mount -o remount,rw /dev/stl9 /system

cp /sdcard/bluetooth/dhcpcd /system/bin/dhcpcd

mount -o remount,ro /dev/stl9 /system

NOTE: The attached zip file is NOT an update file for CWM. It only contains the old dhcpcd file

First off, let me say that I love this ROM!

However, my battery life has not been that great....I have flashed the latest firebird kernel and also flashed a new modem(jl2 I think?) but have had seen no improvements with battery life.

I really like this rom, and I want to keep it. So what else can I do to try to improve battery life? Continue trying different modems? Or can anybody suggest a different kernel I should use with Cognition?

P.S.

The tags for this thread are HALARIOUS!

Battery life note

I flashed this ROM couple of nights ago...first impression: BEST ROM Yet!!!!

As for battery life, I'm currently @ 28hrs with moderate use, lots of email, sms, web, constantly checking the battery level ;) and my battery shows 19%. I'd let it run all the way to 5%, but need the phone tonight, so charging now.

I flashed Cognition ROM 3.0.2, no additional kernel or modem.

THANKS DG!!!!

RE: Wifi Problem with 3.03

Solution for some posted on page 109.....
[Captivate Android Development] halfsoul:
I'm unclear as to what your question is. What makes you think you need a different modem?
[Captivate Android Development] paracutin:
I am not disagreeing with the fact that Cog is based on a factory ROM.

Voodoo alone makes the kernel custom. You cannot argue that. It is no longer as it was released by Rogers. Period! The kernel is different!

I was simply trying to let the original poster know that. It sounded to me as if he thought he was installing a stock ROM which would include a stock kernel.
[Captivate Android Development] xnoctis93:
have rogers captivate running latest cog...has anyone been having the issue where in android market it says your device might not be supported and all the apps are free apps, no paid apps error?
[Captivate Android Development] gk527:
I'm not sure that I do need a different modem. I've seen some people talking about swapping out modems due to speed while on 3G. To be honest, I'm not sure how to install a different one or which one I'd need if I did need one. I assume through CWM. I know you can only install certain ones based off of what kernel the device is running.

Right now, I'm getting 1580kbps down and 304kbps up. On my wife's Aria running Cyanogen 6.1, it gets approx 2500kbps down and 400kbps up. The Aria shows an "H".

...and Thanks!
[Captivate Android Development] s44:
Problem is that you told him that he'd installed the Firebird kernel. Firebird2 is an ALTERNATE option for those who want to go i9000 on the modem/kernel for HSUPA. Standard Cognition is Captivate top to bottom.
[Captivate Android Development] bmwenger:
How exactly do I get the adb shell running and recognizing my phone? The developer documentation is giving me a headache. Is this something I need to run on my phone or on the computer over USB?

Sorry for these questions, I haven't played with the SDK enough it seems.

Thanks for the help.
[Captivate Android Development] c0ldburn3r:
Your speeds are typical for 3G not HSUPA. By default the Captivate rom's don't support this signal. If you want this you will need to flash a kernel such as Firebird 2 then flash a I9000 modem such as JL2 or JK4. Sounds like you want more speed then a stock look so I would recommend trying out Perception 10.2 Perception is based off I9000.

Reading the OP always helps ;)
[Captivate Android Development] m37h:
You said "firebird" and that is wrong. And I said Rogers + injected by Voodoo.
[Captivate Android Development] gk527:
Thanks.

What's "OP" stand for? And where can I find it?

If I do try Perception 10.2 out, I assume I flash it the same way I did Cognition. ODIN to stock, root, install CWM, install from zip file.

If I decide to come back to Cognition, do I need to ODIN first, then restore from a nandroid backup? Or can I restore a Cognition nandroid backup while on a Perception ROM?
[Captivate Android Development] tazman171:
Yeah, I'd say your is a little older, it's June, 2010. Mine is 1007 build; July, 2010 when I got it. I wouldn't think your battery would be crap already but spare batteries are convenient to have and they really aren't that expensive.

For me, stock JF6 was the worst battery I ever had, nothing would keep it going for more than 9 hrs and I have retested that a few times.

If you've had good battery life with other roms I wouldn't say it's your phone/battery. You said that you had bad life with lag fixed roms? Or is it just that all the roms you've flashed (besides stock) are lag fixed?

The lag fix doesn't increase the cpu speed, it is a better file system ext4 (Linux standard ) vs. RFS for the handling of I/O instructions, caching, etc. :cool:

What I did was create a new zip with the old dhdcpd file and am in the process of reflashing now. Hopefully that will work. If it doesn't, does your post mean that I can just find the dhdcpd file in the directory and replace it with the old one without reflashing?

Thanks.

Reflashing didn't work.
[Captivate Android Development] pr0virus:
I know its recommended, but is it absolutely necessary I flash back to stock and master clear before flashing cog 3.03?

Using cog 2.8 at the moment.

Ill probably wipe my phone and set it back to stock before I flash anyway. Just curious.
[Captivate Android Development] froli13:
It can't be included. It can't be fixed. That's why it's not really an issue, it's just a missing feature. As you can read in the OP.

Captivate ROMs + i9000 Kernels = No BT voice calls
[Captivate Android Development] m37h:
I assume you're using CWM method. If reflashing didn't work then copying won't work as well. If you look at the latest update file for cog (to go from 3.02 to 3.03) you can see his changes are launcherPro and the dhcp file (just like the change log says), BUT it will also do a rebuild so the build number will go to 3.03. My suspicion is there something wrong on DG's build.prop, but hey I could be way off, don't quote me on that one :cool:

3.03 is just like the change log says, LauncherPro and dhcpd file, which I did manually from the beginning and I don't have wifi issues, but my build says 3.02.
[Captivate Android Development] c0ldburn3r:
Typically best to odin and master clear before a new flash. I dont really backup apps since i dont use many. OP is usually the devs first couple of posts. DGs roms a fairly bullet proof but you want to look into 3 button download mode and or a download mode jig just in case something goes wrong.

[Captivate Android Development] JGGW:
Yep, recommended to flash back to stock... check out the wiki and the OP (original post). Look at the top of page one :)

As for switching to and from, some people seem to flash right over and others always go back to stock. DG recommends going back to stock and go from there. Every phone is a little different and has it's own quirks...try flashing the long way for a while and then when you are comfortable shorten things up if you need to. That way, if you get yourself into a jam and something goes wrong, you are more familiar with using odin, and going back to stock etc.
[Captivate Android Development] burkebacar:
What am I doing wrong???

I have tried flashing with Odin one-click and with clockwork, and no luck yet. I'm currently running 2.2. When I try clockwork I get a signature error. Any help would be great. I cant seem to get back to clockwork manual mode either. I'm a noob but I feel like a boob for asking.

Since doing the 3.03 update (not the full ROM flash), the WiFi on my cappy is also dead in the water. D/L'ing the full ROM upgrade, and will give that a shot once I get a few more percentage points on my battery (forgot to throw it on the charger last night).

Hopefully the WiFi issue only involves the update-only version, and not the full ROM.

Update: Looks like the issue, at least for myself, was the use of the update-only file. After reverting the phone back to stock, and going through the rest of the 15 minute drill, I loaded the full ROM for Cognition 3.03. End result - WiFi is once again working.

I was having issues with WiFi from the 3.03 update and copied the older version (posted earlier) of the dhcpd using Root Explorer and it started working again.

I suspect that because the only 2 confirmed methods so far are either ADB and Root Explorer (both of which require changing R/W options on System) that the CWM method may not take into account the same way. (just a shot in the dark)
