Flashing the B2 kernel works, but it isn't the most recent kernel. B2 contains the older version of CWM, and I'm not sure what else is different.
[Captivate Android Development] joseverdin10:
I was wondering if the bluetooth protocols are the same as cynogenmod 7? I'm attempting to get the "Sixaxis Controller" apk working on my phone, but currently, it appears my cognition 4 rom's bluetooth protocols are unsupported. Since I've used cognition for such a long time, I would hate to switch to cynogenmod just to get the app working.
[Captivate Android Development] jlsesler:
I flashed the rom, and I got stuck like others have posted. I powered off and booted into recovery. I got this message:

E:Can't mount /cache/recovery/command

E:Can't mount /cache/recovery/log

E:Can't open /cache/recovery/log

E:Can't mount /cache/recovery/last_log

E:Can't open /cache/recovery/last_log

The recovery screen is there, but none of the selections are responding. Hopefully this gives an insight to the problem.
[Captivate Android Development] skullvet:
Go back into download mode with odin and reflash beta 2 kernel. That will get you out of that and back to KF1. I haven't found a way to get cog 5 v2 working. Will work for DG to update the kernel.
[Captivate Android Development] designgears:
The button layout works different..

vol rocker is moving up and down, power is back, home is select.

------------

Updated the OP with new instructions and initial kernel!!
[Captivate Android Development] araxian:
i get it the original initial cog5-beta2-kernel.tar, didnt have ext4 support but the kernel in Cognition5-v2.zip did.

so when you flashed the rom under cog5-beta2-kernel.tar, it couldn't create the ext4 partitions.

So when the kernel from Cognition5-v2.zip booted it looked for partitions in ext4 that weren't there so it got stuck.

That's why reflashing the cog5-beta2-kernel.tar, went back and booted to KF1, as most of the rom was never installed it just went thru the motions.

I see a new init kernel cwm flashable on pg 1 ill try it and see. :)
[Captivate Android Development] skullvet:
worked. v2
[Captivate Android Development] othermark:
The capacitive home button works in recovery now? I gotta see this.
[Captivate Android Development] RKight:
Omg...this is effin' awesome. This is what I've been waiting for. I'm about to flash it right now. :) Oh and I remember tons of people saying ext4 wouldn't be possible without kernel source...and I told them it *was* possible since we had voodoo on JI6 without source. :D
[Captivate Android Development] Xenocide83:
New Kernel Link Please

Does anyone have a link for the new Kernel that does NOT lead me to a File Share site? I am at work trying to flash the new version and they have filters in place for Filer Sharing sites. Thanks!
[Captivate Android Development] squishy5:
can this be flashed dircetly over a jvr rom like apex v9.0
[Captivate Android Development] RKight:
Here you go.
[Captivate Android Development] designgears:
Hahaha, I have known it was possible all along, just didn't put time into it. Looks like you weren't crazy after all :D

It is very possible it is ext3 mounting the ext4 partitions, I will look into that, but I am pretty sure the kernel has ext4 and some other ones already enabled. Either way it won't matter :)

Sorry about that, I will host it on my ftp when I get home.
[Captivate Android Development] shinji257:
Anyone having issues with this release?

I actually had to revert to 4.5.3 due to mine on v1.

1) Memory leak issues (unusable after a few days)

2) GPS crashes

3) Battery usage was high

Holding off in v2 until it has been tested a bit.
[Captivate Android Development] prbassplayer:
The Memory Leak issue i believe its a KF1 thing, I've had it on both Cog 5 and AF. As to battery usage It really depends on what you are running. GPS crashing might have been a bad flash? did you try reflashing it?
[Captivate Android Development] prbassplayer:
Cog 5v2

I got v2 running and as for benchmarks, I don't see a difference on Linkpack or Antutu, but Quadrant got a 600 point boost from Beta 2 (ya i never benched marked v1) and 500 points on AF 1.4. Going to test daily use smoothness today. Thanks DG for the great work man.
[Captivate Android Development] RKight:
Hey, I'm just happy it's not rfs. Lol. I mean, both ext3 and ext4 offer great performance. I've been a linux user since Redhat 5.2 (about 12-13 years) and I don't think I've really noticed any major difference in fs performance since I made the switch to ext4 from ext3. I'm just glad you decided to come back and show us some love. I always try new ROMs and I almost always come back to yours. I kept CM7 for a long time but got sick of the battery life. I saw Cog 5 as a good reason to jump ship. Then, I lacked ext4, so I went to some i9000 based ROMs but had weird charge issues. I finally went to Cog 4.5.3 for the stability and ext4. Now that Cog 5 has ext4, I think I've found a winner. I think my only request at this point would be to add the lockscreen mod. I don't even care about the five lockscreens, or ten lockscreens, or whatever it's up to now. I just want to be able to pick the AOSP one without having to flash another zip. Speaking of that, though, will the one that was posted a while back work with this version? You didn't make any changes to the framework, right?
[Captivate Android Development] :
So what the difference between the two roms? I know that EXT4 is needed in the kernel, so why the rom update?
[Captivate Android Development] sstarre:
Yeah squishy, I just did it from Apex 9.

I was already on ext4, so I flashed the kernel with SGS Kernel Flasher (NO REBOOT) then used the extended power menu to go to recovery, wiped & factory reset and flashed the Cog5 zip from the sd card... worked perfect... :D
[Captivate Android Development] BigEHokie:
Unfortunately I still get the same result with this download.

I flashed to UCKF1 stock, used your download (extracted the zImage and created a tar) and used Odin 1.82 to flash (it said success, I'm assuming it was) and then I'm still stuck on the at&t boot screen. I haven't tried to flash Cog yet.

Went into CWM and tried to flash the exact zip you supplied, successful flash but still stuck on AT&T boot screen.
[Captivate Android Development] RKight:
The way I did it was as follows: I flashed UCKF1 using the one-click app. Then, I flashed the Cog Beta 2 kernel in Odin to gain Clockwork recovery. After that, I rebooted into recovery and flashed the Cog v2 initial kernel, rebooted into the new recovery, and flashed Cog 5 v2. I rebooted and bam...booted like a champ.
[Captivate Android Development] planetdroid33:
Tried installing this rom and got stuck at att screen as well. waited a few minutes and screen went blank. Wont charge go into download mode. So does this mean my phone is bricked.
[Captivate Android Development] designgears:
No changes to the framework from v1.

Now we are just missing Voodoo Sound, but you can buy the app to make that work. So I guess it all works out :)

on a /system level, the entire filesystem changed, so if you use the kernel and just wipe, what are you going to boot into?! ;)

After you flash the v2 kernel you need to do the key combo or adb to get into recovery and flash the rom again.

As I stated a page ago, if you flashed and got stuck, simply boot into recovery, flash again and it will boot.
[Captivate Android Development] BigEHokie:
Thanks for the instructions, I'll try this out to see if it works for me.
[Captivate Android Development] wibi795:
ok!! so ive found a very anoyong thing "device low on memory'' toast drives me crazy
[Captivate Android Development] RKight:
Definitely. Especially with Tegrak's OC app. :) And, honestly, I had to buy an iPod Touch to use at work (which makes up 95% of the time I listen to music away from my computer), so I can live without Voodoo Sound. I kept getting accused of texting at work, so I had to get the iPod so my boss can no longer accuse me of such. Of course, I was texting. And, now, I just use the MobileAP feature of my phone to connect my iPod to the internet, and I use Text Plus to text people. I tell her I'm searching for a song, or typing in my "journal". :D
[Captivate Android Development] :
Did you forget to flash the butter&jam.zip?
[Captivate Android Development] RKight:
Lmao! 10char
[Captivate Android Development] wibi795:
not available
[Captivate Android Development] BigEHokie:
This finally got it for me. I thought after I flashed the new kernel (and before flashing Cog 5v2) I could boot into the device. That doesn't seem to be the case..

Thanks again.
[Captivate Android Development] RKight:
You're very welcome. You can spank my thanks button if you want. :D I'm definitely glad you got it working...any DG ROM plus ext4 is a win. :)
[Captivate Android Development] yoderk:
5v2 is smooth as butter! Haha Nice work DG!
[Captivate Android Development] RKight:
No kidding! Holy crap, this is fast! I might not even overclock. I've noticed one of the most annoying delays ever is when I first restore Beautiful Widgets and go to advanced settings to set the apps for the time, date, and forecast applications. Normally the wait is excessive, even under Froyo ROMs with ext4. Under Cog 5 with ext4, though, it was just a second or two. I was very pleasantly surprised. :)
[Captivate Android Development] dotuananh88:
I wonder why the developer can not put the GSM/ WCDMA/ Auto .. into Settings menu ? It is vital for a rom. I will never use a rom that does not have this setting. Therefore I use Apex 9.0 or 8.3 with i9000 boot, much more smoother, faster, and of course, we can change gsm/ wcdma on settings menu
[Captivate Android Development] RKight:
I've never had a use for that. Vital, indeed.

Oh and your "more" was a bit redundant. I think "much smoother" would have sufficed (and would also have been proper English).
[Captivate Android Development] flintdragon:
So correct me if I'm wrong, if I'm already on Cog5v1, can't I just flash the Cog v2 initial kernel and then the full rom? Or do I really need to go all the way back to KF1 stock?
[Captivate Android Development] wgarrido:
Are you talking about DG or AT&T? We need source for DG to do it.
[Captivate Android Development] :
I know that most people have seen that after about 3-5 days of use the phone slows to a crawl as it approaches only about 50MB of RAM (probably due to a memory leak) remaining. What Im wondering, is if EXT4 will help with that and still keep the phone speedy after 3-5 days of consecutive use and only 50MB of RAM available. Does EXT4 make up the difference?
[Captivate Android Development] RKight:
I don't see a reason why you would necessarily have to go back to stock but I do it every time just to be safe. I've had issues where I've flashed from one i897 ROM to another, or from one i9000 ROM to another, and ended up with bootloop issues, FCs, etc.
[Captivate Android Development] RKight:
No. The memory leak issue has nothing to do with the file system. Personally, though, I reboot every other day or so anyway. It only takes a minute and it keeps the memory leak and the AOS bug in check. It's really not a big deal.
[Captivate Android Development] flintdragon:
Yeah, normally I would do that too but now that it takes so many steps for v2, it would reduce the chance of something going wrong. :)

kf1, beta2, initial kernel, full rom
[Captivate Android Development] dotuananh88:
Because I am very happy with cognition 4.5.3. It has all things that I need. If cognition 5.2 has these settings, I will flash it immediately !. Hope that in the next version, the developer can put it into the settings menu.
[Captivate Android Development] jeromekobriger:
I've tried flashing v2 both ways, one from Cog 5v1 to v2, and one with full wipe using the one click method to stock, then following DG's instructions.

Both ways will not let me boot; it just gets stuck at the at&t screen. Any suggestions?
[Captivate Android Development] :
I actually reboot every morning after I take my phone off of the charger. I unplug, reboot and throw it in my pocket. By the time I go out to my truck, its back up and ready to go.

I realize that the file system has nothing to do with the memory leak, but I was wondering if EXT4 did speed up the file system enough to where the phone did not lag when it hits 50MB or less.

Also, when I was on Serendipity VII and other i900 roms, I didnt see my phone slow to a crawl when there was only 50MB left. Im also wondering is that the limit of our phone (50MB free) or does it just seem to be present in this particular rom leak as a "feature"?
[Captivate Android Development] Donmotobike:
Great work DG!

You have Galaxy 2 for couple weeks and you're back on Captivate already? lol jk Great work DG on Cog 5 beta 1 but I'll wait for beta 2(planned items installed) - so how is Galaxy 2 - should we all get one soon or wait....

Thanks! Cheers!:D
[Captivate Android Development] tbong777:
Yeah he did but I believe on an i9000 base.
[Captivate Android Development] cumanzor:
This ROM:

- Easiest GB installation.

- Most responsive GB rom *without* any tweaks yet.

- AWESOME battery life.

DG, give me a couple of months to give you a *nice* donation. I'm too broke right now unfortunately : P
[Captivate Android Development] tbong777:
Could not hold out..

Initial flash was scary... Big red fail at SBL.Bin....Pulled battery, went into DL mode and re flashed.....Looking forward to updates.
[Captivate Android Development] Tritan88:
I couldn't hold off either. I flashed this morning and so for so good. I have to work on some tweaks for the battery though.

Great work DG. I look forward to your updates.
[Captivate Android Development] greeto4:
I take it this will replace both primary and secondary bootloaders that I nstalled for GB, and will not brick due to mix and matched bootloaders?
[Captivate Android Development] xpakage:
Correct.

Wow nice to c you glitterballs I havent seen much of you in a while hope life is treating you well.

hope to see some more posts from you.

Awesome ROM

Thank you DG, the battery life after flashing your ROM is phenomenal, I never had such good battery life ever, here are some screen shots

GPS

Are you serious? I can't get a lock at all with Cog5 b1. Is anyone else having problems with GPS or is it just me?

I was using a CM7 nightly and the GPS was amazing. If I can't figure this out I'm going to go back to CM7. Any help would be much appreciated.

Thanks
[Captivate Android Development] gstern:
I'm having second thoughts about flashing this. mainly because in about 10 hours I'm going out and won't be anywhere near a PC for the next week.

how does this build perform in terms of stability? (i already see feedback about great battery life)

how does rfs on GB compare in terms of speed and smoothness vs ext4 froyo roms?
[Captivate Android Development] johnhazelwood:
My pin lock isn't working. I just get the standard slide to unlock screen. Anyone else?

Update: unlock shows on first boot, but then glass unlock after.
[Captivate Android Development] KappaG9:
Won't restore to stock with ODIN either, my phone is screwed
[Captivate Android Development] 1tontomato:
Sometimes the urge to flash the latest and greatest is strong, but if your not gonna be near a computer for a while it's ok not to flash, especially since this stuff moves real fast. In a week this might just be cog 6.3.

Sent from my SAMSUNG-SGH-I897
[Captivate Android Development] 4-2ndtwin:
Thanks again DG for the great work.
[Captivate Android Development] RKight:
That's probably the best policy with any ROM. I've even noticed my computer acting a little odd if I don't reboot it every so often. I got into the habit of hibernating it every day, rather than shutting it down, and I noticed that, after a week or so, my computer would be a little sluggish and start having odd little problems here and there. This was under Windows, of course, and not Linux...but still. Regardless, whether using Windows or Linux, I shut it down at least every few days to ensure a clean boot.
[Captivate Android Development] z28james:
Some people (including myself) live in an area where EDGE is stronger than 3G (at least at my house). With that being the case, before I go to sleep or when I notice weak 3G signal, I'll put my phone onto 2G only to avoid using more battery than I need to. I'll flip it back on when I need to do some browsing or something and don't want to wait on EDGE.

And about the grammar nazi thing: you obviously understood what the person said regardless of their grammar and is that not most important? I realize that you didn't have a valid reply to their comment (of course, if YOU have never had a reason to use it then nobody has) but that's no reason to attack their grammar.
[Captivate Android Development] skullvet:
The exchange email apparently doesn't work as far as autocorrect / capitalisation with android keyboard. Same thing with beta 2
[Captivate Android Development] RKight:
Edit: Not gonna argue. Not really worth it. :)
[Captivate Android Development] chasesavestheday:
going from cog 5 v1 - v2. flashes kernel via cwm, flashed rom via cwm. getting stuck at AT&T screen. what'd i do wrong?
[Captivate Android Development] RDI:
I also get "stuck" on the ATT screen after flashing the Cognition5-v2-initial-kernel. both thru CWM and Odin. Even tried one after the other,no luck getting to 5 v2. Back to 5v1.

I even tried starting on step 1 first, no luck.
[Captivate Android Development] mbc663:
wont long pressing the power button and disabling data do the same thing?
[Captivate Android Development] z28james:
Yeah. Not much you can really say when you are wrong. I understand. Hopefully you can simply leave other people alone next time.
[Captivate Android Development] chasesavestheday:
I also tried stock > step 1 > the rest via cwm. still stuck at at&t screen. hmm.
[Captivate Android Development] RKight:
Now, see, I was trying not to be a troll. I had typed up an argument justifying my statements but I decided the development forum wasn't the proper place for it. Personally, whether I was right or wrong, I feel this isn't the place for petty arguments. Hopefully you will understand *that* and end this now.
[Captivate Android Development] shinji257:
Yes I did. Fully clean install starting with JF6 and went from there. As for memory leaks I think I had it on Apex as well. It may be memory leaks. It may be something else. All I know was that the phone slowed to a crawl after about 3 to 5 days depending on use.

P.S. - When changing between releases (i.e. Android 2.2 vs 2.3, ect) I've always been going back to stock and starting from there. I had to reflash my phone 4 times while messing with my phone on Cog 4.5.3 due to stupid errors on my part. I've learned to be more careful when messing with /system and that it can run out of space for no obvious reason.
[Captivate Android Development] z28james:
Hopefully, next time you can leave your grammar nazi nonsense out of the development forums to begin with. Then, next time this gets ended before it even begins.
[Captivate Android Development] RKight:
Touche, sir. Touche.
[Captivate Android Development] z28james:
Well, now that we are done being douches to each other.

How are you seeing the memory leak in KF1? Just checking the free memory in settings?
[Captivate Android Development] godpancho:
100% full install.No boot loop

to install this rom you must be on stock at&t gingerbread with cog5 beta-2 just like step one and two in the install guide on first page. then put the cog5 v2 rom and the Cognition5-v2-initial-kernel in ur sd card. turn off phone boot in to recovery and install Cognition5-v2-initial-kernel but do not boot up the phone go to advance and reboot intro recovery. now you get a recovery that says

E:Can't mount /cache/recovery/command

E:Can't mount /cache/recovery/log

E:Can't open /cache/recovery/log

E:Can't mount /cache/recovery/last_log

E:Can't open /cache/recovery/last_log

but thats ok.

now you have new key combos in this recovery. vol up vol down still do the same function but the power botton is now back function. and home button is to select. so just do like any normal rom and wipe data,cache and delvik. now install cognition 5 v2 and reboot phone.

everything should install correct

hope this helped
[Captivate Android Development] mbc663:
you spelled douche wrong ;p
[Captivate Android Development] RKight:
That's the only way I've noticed it. I usually make it a point to reboot on a regular basis, though, mainly to prevent the AOS bug. As a side effect, the memory leak issue basically becomes null and void.
[Captivate Android Development] RichIrish:
A note to all those stuck at the AT&T screen after installing Cog5v2 -- I was stuck at the same point after going back to JF6, performing a master clean and going through steps 1, 2 and 3.

Here is the fun part.. Just pull the battery out when stuck at the AT&T screen and reboot into recovery with CWM. Your CWM should behave different i.e., your home key is for selection and up and down volume keys help navigate the menu options and the power button serves as a 'back' button. Go ahead and re-install the Cog5v2.zip again and VIOLA.. it all starts working like a charm.

Good luck!

Great work DG! You are the best!

P.S. - Don't forget spanking the "Thanks" button if this post helped you. ;)
[Captivate Android Development] melvinaury:
Can some one give me the link to the previous Kernel, that we use to install the version 1.0. I'm currently on Stock 2.3.3 KF1 and need the kernel to be able to enter ClockworkMod Recovery, to install the new kernel and ROM.

I just erase the previous kernel.:eek::eek:
[Captivate Android Development] sstarre:
LMAO
[Captivate Android Development] RKight:
Here you go. :)
[Captivate Android Development] chasesavestheday:
Got it to work, went stock > KF1 > flashed vs kernel via odin rather than cwm > flashed rom via cwm. did not get stuck at AT&T screen this time! Wow its fast! Also anyone else notice the power widget is...well none of the buttons are there?
[Captivate Android Development] RKight:
Yeah. :( I can't remember if this was a problem with the previous versions of Cog 5, or not. I remember having the problem with some version of GB, though (it may have been an i9000 ROM).
[Captivate Android Development] chasesavestheday:
It worked fine with C5V1..
[Captivate Android Development] Romee74:
This was an issue with early gb roms but i cant remember what the work around was. It was a simple work around. I think it was enabling all the options and then disabling them all from the notification menu.
