[Captivate Android Development] rajendra82:
Why exactly are you wanting to flash just the JJ4 modem if you are planning to keep the OC/UV kernel which is compatible with the JK4 modem and will give you voice calls and HSUPA at the expense of bluetooth? Flashing back both the JJ4 Voodoo kernel and JJ4 modem make sense to me, as that gets you back to a fully Captivate based ROM with no voice call/bluetooth issues and consequently no HSUPA. Just the JJ4 Voodoo kernel but keeping a non Captivate modem doesn't work for voice calls. What is the effect of just flashing the JJ4 modem over 2.3b7 other than the loss of HSUPA?

I did a clean upgrade to b7 and now the Genie widget force closes on open after I installed it. Is anyone successfully using the News & Weather widget on b7?
[Captivate Android Development] rajendra82:
No problems here. I am not on the pure 2.3b7, but the Captivate back ported version.
[Captivate Android Development] ryboto:
What would be the issue with using this rom with Jl3? I'm actually using jj4 voodoo kernel, would I have issues if I flashed the JL3 modem? I mean, assuming it doesn't brick the phone I can always go right back to JJ4. Has this been done? Are there known issues? I did a quick search, didn't find anything in this thread or the TLJL3 thread.
[Captivate Android Development] cgkruger:
Just wondering if anyone else is having random lock ups with the camera in particular. I can reproduce the issue with barcode scanner; the program will lockup the phone 100% of the time.

I have had this issue also. In addition I have seen an issue with the share function on pictures. Photo's fail to send when sent to multiple users unless I go into messaging and pic the users and attach the photo.

Also, is the lack of protrait view with auto rotate on the home screens a feature or an issus? I know b6 did the same thing.
[Captivate Android Development] rajendra82:
I flashed JL3 yesterday. I can't remember if at that point I was on 2.3b6 or 2.3b7 plus the JJ4 voodoo kernel. There should be no issues in terms of flashing the modem or any chance bricking the phone. What you will find is that the JL3 modem and JJ4 voodoo kernel won't work together properly in all situations. You will have HSUPA for data but will have no audio in voice calls. I am not sure if Cogkernel 2 and JL3 will play together well, but my guess is they do.
[Captivate Android Development] theMaDHakkeR:
All i was trying to do was to see if its possible to use the JJ4 modem with the OC/UV Cogkernel2 so i can keep OC/UV and have working bluetooth. However from what im reading i dont think its possible. Seems like we have to flash the JJ4 Kernel + Voodoo with the JJ4 Modem for this to work properly.

I guess ill leave it as is for now, i dont use bluetooth too often anyhow.
[Captivate Android Development] rurouni572:
Cogkernal2 and jl3 indeed play well together. I was doing that before switching to supercurio's kernal.
[Captivate Android Development] ryboto:
Yea, just found out with the jj4 voodoo kernel there's no audio in calls. I'll look after I post this, but is Cogkernel2 available for download anywhere?
[Captivate Android Development] rajendra82:
You'll have to strip the zImage out of the ROM, put it inside a kernel updating zip file (like the one Supercurio posted). Put the modified zip on your sdcard and run it.
[Captivate Android Development] ryboto:
I just saw the file structures were the same, but wasn't sure if it would be that simple. Thanks!

edit:

just an update for linpack/quadrant scores, not sure how much they matter or whether or not they're an accurate gauge of performance. These are my scores for different configurations with 2.3b7:

Cognition 2.3b7 OC/UV: 15/1000-1100

Cognition 2.3b7 JJ4 Voodoo Kernel+ JJ4 modem: 12.5/1550

Cognition 2.3b7 nonOC+JL3 modem: 14/900-1000

The second configuration was the only one that had consistent quadrant scores(scores all within 10points of eachother) over several tests, the others always fluctuated.
[Captivate Android Development] tazman171:
I had this happen but it was when flashing to stock, usb drivers quit on me. I left the phone off with no bat, usb, sim or extSD in. I opened odin one click and plugged the usb in. Take the battery and just barely make contact with the bat contacts on the phone while pressing vol+- then pull the bat away. Do this repeatedly until you either 1) see 6 lines of red text, if this happens, unplug the usb and hold power for 10 secs and repeat the battery touch steps or 2) it will suddenly pop into download mode.

I know it sounds crazy but I found part of this info in a forum and it worked although it takes patience and I was at it for at least 45 mins. When it finally went to download mode I clicked start in Odin and got it flashed back to stock.

I thought it was bricked as I had no charge screen, button lights, vibrations, etc. This worked for me and at least one other person since I did this, albeit with a huge dose of patience. Make sure and re-download the rom before you try to flash it again.

Hope this helps. :cool:
[Captivate Android Development] bedspringlex:
This is working great for me. Thanks. RKight. I always jumped back to 2.3b3 I find it to be the most stable. But your version is fast and stable.
[Captivate Android Development] novalovr66:
Flash doesnt work!

Ok, here is the scenario. I was running 2.3b6 then wanted to try 2.3b7. Everything was fine and I couldn't live with bluetooth static so I wanted to flash back to 2.3b6. Well I used ODIN to flash back to stock (I897UCJI6-OCD-REV02-Low-designgears) Now this is where the problem starts. I lost superuser so I used SuperOneClickv1.5.5-ShortFuse to root and got superuser installed. I went to the market and made sure that I had updated to the latest version. At this point, no matter what I do, I cannot get into Clockwork recovery. Every time I try to install from SD card using ROM manager it gets to verifying packages and stops at "E:failed to verify whole-file signature

E:signature verification failed

Installation aborted"

What am I doing wrong?:confused:
[Captivate Android Development] Pirateghost:
JI6 is not stock....thats leaked 2.2 ... you need the ONE CLICK ODIN JF6
[Captivate Android Development] novalovr66:
So if I flashed to JF6 everything should be fine? Will try that now!
[Captivate Android Development] novalovr66:
Ok, looked for it and found One click Odin JF6 but it only comes with a pit file. What else do I need to get this working?

Never mind, I found it.....

[Captivate Android Development] bryrzn:
hey guys, im new here.. what rom would u recommend me, i want a very stable rom and the battery is superb. pls help me.. i want to flash my captivate now ;)
[Captivate Android Development] Soulweaver:
Kinda freeky how the phone starts talking like a robot after you install the rom lol
[Captivate Android Development] s44:
You should ask in the general forum, not a ROM-specific thread.

That said, if you want stability, I would avoid anything with an overclock kernel.
[Captivate Android Development] bryrzn:
i want cognition rom thats why i post it here but what version do you think? thanks
[Captivate Android Development] wokie:
I am having some crashing problems. It shuts down overnight. I think I am running the one with the wrong kerenal. Could that be the problem?
[Captivate Android Development] sinichi21:
what kernel are you running? I believe these issue happen if your running an oc/uv kernel try using a non-oc/uv kernel never get a charge of death
[Captivate Android Development] s44:
Yes. Overclock kernels tend to have the sleep death/crash issue.

I would advise all newbies (i.e. anyone who has to ask) to flash 2.3b7 *only* with the non-OC/UV kernel (the first DG package), or -- given that DG has inadvertently packaged a i9000 kernel/modem in with a Captivate ROM -- better yet the repackage above of 2.3b7's ROM with supercurio's stock Captivate+Voodoo5 kernel and Captivate JJ4 modem.

In your case, since you already have the rest of the ROM flashed, you can either rip out the non-OC/UV CogKernel2 from DG's full 2.3b7 package and flash that (somewhat complicated method as here), or just flash the first package here. Either way you'll want to use red CWM -- three-button into regular recovery, apply update.zip, then in the red menu pick the zip package to flash and select it... (Actually, I haven't tried it but I think Cog still has the power menu mod in it, which means you can just select "reboot to recovery" from there and you'll go straight to red CWM.)

A UV-only kernel would be nice for battery life, but I think all the current UV-enabled ones have OC built in as well.

Works amazing... One thing, I tired installing a one - click lag fix. Don't think it worked, and now my phone says "convert data partition, system is not found" on boot up. What does this mean?

Thanks!

[Captivate Android Development] cwgannon:
This is what I'm hoping to do; however, I will lose the BackLightNotification that was added in 2.3b7, correct?

I've seen the installation thread, but I'd be a bit optimistic to think I could do that without running into quite a few headaches (if I get it working at all).

Thanks.
[Captivate Android Development] s44:
Yes. I believe BLN is only on i9000 kernels for the Captivate at the moment. There's nothing wrong with that -- and there are some non-OC BLN kernels -- but you should switch to one of the i9000 ROMs+modems for that. Don't have to look far: every other ROM besides Axura (Vibrant) qualifies. ;)
[Captivate Android Development] s44:
Don't mix OLCF and Voodoo. It's also unnecessary: Voodoo5 *is* the lagfix, and a heck of a lot more stable.
[Captivate Android Development] rajendra82:
If you flash over Supecurio Stock + voodoo 5 kernel over already installed 2.3b7, you will also have to flash the JJ4 modem from here. This will get rid of all the non-Captivate bits in 2.3b7.
[Captivate Android Development] mejori:
I agree 100%
[Captivate Android Development] s44:
According to the filename at least, the modem is now included in supercurio's kernel flash package.

Sent from my Voodoo-powered Fascinate with XDA
[Captivate Android Development] rajendra82:
There is no JJ4 modem in the Supercurio update package. Only the JJ4 kernel with the voodoo5 lagfix injected in the initramfs. I just downloaded it again to check. If you flash the Supercurio update, the JK4 modem that got installed with 2.3b7 will still be left behind.
[Captivate Android Development] cumanzor:
thanks. my phone is shutting off overnight too (if plugged in).

I went from stock to 2.3b7 (OC/UV). I have a nandroid backup of the stock phone, but I read you cannot go from 2.2 to 2.1 with clockwork recovery, correct?

What I have to do is to use Odin3 to go back to stock, then I can either restore my nandroid backup or flash any other roms, correct?

Now, before I use Odin, do I have to disable lagfix?

[Captivate Android Development] tazman171:
Right below the download link for Cog on the download page, it says: flash back to I897UCJF6. That's the link. :cool:
[Captivate Android Development] m1armor:
you use that odin and just load the files?
[Captivate Android Development] tazman171:
You use the one click to flash back to the stock JF6 rom that was shipped with the Captivate. Android 2.1 Eclair completely stock setup. From there you can get your original android ID, root, install rom manager, flash Clockwork and then flash the new rom using rom manager.

Read the FAQ and Wiki links on DG's download page for his recommended way of preparing for and doing the flash.

Go to the first page of this thread and click on the download link for all the links I'm talking about, you should always read the OP's first page and follow their instructions to the T until you are totally familiar with flashing to make it a good experience. :cool:

Exchange

Not sure if this is a problem with Android, Cognition or Captivate.

A couple of days ago I decided to forward a copy of my emails from my exchange account to my gmail. I left the exchange account setup and changed the frequency from Push to Never.

After that- WOW! My battery life went from 8 hours to....well lets just say that after a whole day of use (8AM-10PM) my battery says 60-70.

I have 3 gmail accounts, twitter, facebook, and I use my phone a lot.

Is this a problem with cognition or is it on any android device?

This isn't the best setup since I like to have all my sent items on my exchange server as well. I also think that it's easier to open attachments and add them on the exchange email client rather than with gmail.

Is the email.apk provided by google or is it customized by Samsung? Is there any way to make it more efficient or is it an exchange problem?

I dont see anything about what you said using clockwork and ect... thats why I asked
[Captivate Android Development] theMaDHakkeR:
There are a bunch of threads on how to use clockworkmod. Just download ROM Manager from the market, flash clockworkrecovery through rom manager, and then reboot. Hit reinstall packages if you got to the stock recovery after first reboot. Select install zip from sd and then go find your rom. Dont rename, dont hit it, dont smack it. Just make sure you do an nandroid backup when your in clockwork recovery.

I also highly recommend making a backup of your nv-data partition/efs folder. You do not want to lose your IMEI trust me.

Im assuming your already rooted, and have the .zip in the root directory of your internal sd card.

v2.3b7 Non OC/UV vs v2.3b7 OC/UV

I'm currently run stock eclair from rogers (I896). I'm going to install this rom, which I heard so many good reviews. Now I'm going to download the rom which one do I select and whats the difference (v2.3b7 Non OC/UV vs v2.3b7 OC/UV). Should i install the rom over my eclair or install the other one provide. I want froyo so bad
[Captivate Android Development] m1armor:
I did the clockwork but it failed so I had to install factory 2.1 with odin bc it got stuck at the world phone screen
[Captivate Android Development] theMaDHakkeR:
Im with Rogers and just did the same thing.

I went with the Cogb7 OC/UV. This ROM runs the phone at a max of 1.28Ghz. The Non-OC/UV version runs the phone at stock 1Ghz.

You need to root your phone, install Rom Manager, and then flash clockwork recovery. Put the .zip you download in the root of your internal sd card. Make sure to do a nandroid backup of your current rom, and also back up your efs/nv_data partition using ADB. <----- This is important because if you lose your IMEI and didnt back that up, you need to ODIN back to stock and start over.

Remember that with the I9000 Roms you will get static in the bluetooth so it wont be usable, but everything else works, and upload speeds reach 1,600kbps+ with this modem for me.

Regards.

EDIT: Come to think of it i dont know if going to stock with ODIN will get back your lost IMEI if you didnt back it up. Might be a trip down to your local Samsung service center.

Maybe someone can clear that up.

Flash JJ4 Voodoo Kernel+ JJ4 modem to get rid of bluetooth static and have fully captivate kernel. You will lose OC/UV and kernel hacks from the I9000 kernel but gain bluetooth.

I think this is an issue with the I9000 kernels so i dont think there is an easy fix yet.

[Captivate Android Development] s44:
It's very odd that people are getting into ROM flashing without even the basic knowledge of what's going on.

You can and should use Clockwork to flash *anything* for your phone. Any package ending in .zip is designed to be installed this way.

First, you get into Clockwork. Either go directly into it from the power button menu or the Reboot Button app ("reboot to recovery" in either case), or go into the default recovery and select "apply sdcard:update.zip". Clockwork is sitting inside the "update.zip" file on the root of your SD card, so selecting it from the regular (blue) recovery will bring you into Clockwork (green -- standard; red -- Voodoo5) recovery.

Second, navigate to "apply zip from SD card". Note that while the volume keys are up and down in all versions of recovery, the "select" and "back" buttons (and others) are different in each (blue stock, green Clockwork, red Voodoo5 Clockwork). So don't freak out if your screen goes blank after you hit what you thought was the "select" key.

Third, select the zip file you've downloaded to your SD card.

Fourth, you may want to wipe cache in Clockwork, or data and cache if you're flashing a whole ROM. When you're done with all that, select the reboot option.

[Captivate Android Development] rajendra82:
Cognition 2.3b7 stripped off of the i9000 kernel and modem and and installed instead with the Supercurio JJ4 voodoo 5.x kernel + stock JJ4 modem may be the only way at this time to fully solve the charging/sleeping death bug. The modem is not causing the issue, but you have to replace it with the kernel. The Perception Build 9 change log indicates that Cogkernel 4 still suffers from random charging death. It is possible that the SetCPU fix posted in the new dev thread by designgears will solve this once and for all, but going full Captivate with 2.3b7 will most certainly cure what ails you.
[Captivate Android Development] sandshifter:
so your saying i should get the i9000 kernel, correct ?
[Captivate Android Development] rajendra82:
Which part of strip out i9000 kernel and replace it with Supercurio 5.x voodoo JJ4 kernel meant, get the i9000 kernel? Since your are on stock now, what you need is the repackaged 2.3b7, that includes the Supercurio JJ4 kernel and stock JJ4 modem. This was posted a few pages back in this thread. When you install the repackaged 2.3b7, you should not see charging death, as the offending components are absent.

Bluetooth static on Cognition2.3b7

I've installed Cognition 2.3b7. Bluetooth is static only, can't use it at all (as promised on designgears site). Does anybody know a fix to a bluetooth issue? I like that particular ROM build and prefer not to downgrade if possible.
[Captivate Android Development] s44:
Flash a Captivate kernel/modem. Read the thread.
[Captivate Android Development] s44:
You're right! Thanks.

OK, to make it easy for people, I've combined the kernel and modem into one package:

stock Captivate Froyo kernel + Voodoo5 + Captivate JJ4 modem

It's unsigned, so flash in CWM (red or green recovery) only, not stock (blue).

This should take out all the overclocked and i9000 parts of a currently-installed Cog 2.3b7. So no sleep death, bluetooth static, etc.

If you haven't installed 2.3b7 yet, look at full ROM + Cap kernel + Cap modem repackage above to do it all in one go.
