Hello,
I've read all I can here. Sorry if its been posted before. I love the Cognition ROMs and am keen to try out HSUPA (JG8 modem?) on one of the more recent versions.
The lower pings and faster upload is so tempting. Looks like the Geomod ROM will break bluetooth streaming / phone calls which I also need.
Anyone done this - and had any luck? Any guides on how to do this - how to enable and find different bands (850Mhz, etc..) and how to return to stock modem (JPP) as needed? ....
Ideally I'd like to switch modems... JG8 vs JPP with my Cognition ROM.
Thanks anyone who might have advice!

Please search within the Captivate sub-forums to find the answer to this question. It has been discussed in great detail already, and there are quite a few step-by-step guides floating around.
Just to point you in the right direction though: To get HSUPA working with any 2.2 ROM (at least so far) you need to flash the JG8 modem FIRST before any other modem interacts with FroYo. This "enables" the 850 MHz band which you will need if you plan on using 3G w/ AT&T in America. Then you can flash the HSUPA enabled modem of your choice after (I prefer JPP, but others will work). Also, it's worth noting that i9000 radios (which all of the HSUPA enabled ones are) tend to play better with i9000 kernels. Meaning that if you are running cognition, you may want to switch to a i9000 kernel to go with the i9000 radio you are trying to install.
Happy searching!
After much reading, searching, study and experiment I'm reasonably sure you can't get hsupa AND bluetooth working on a captivate rom, like cognition. I've only been able to get both on an i9000 rom.
Using doc's for cappy by mikeymike with the setiron kernel. Both work, the bluetooth not always well. The unfortunate part of this one is that wired headsets are fubar. Don't work at all. Other than that, the rom works great.
You NEED an i9000 reorient kernel (not ROM) for voice. As you noted, data works fine, but wait till you make a call.
You can pair cognition with an i9000 kernel, however, you may have weird bugs.
Best option is to use i9000 ROM + i9000 reorient kernel + i9000 modem, all froyo.
Jg8 is eclair and only used temporarily to enable 850 mghz.

IBTL.
This is subjective as all hardware is not the same. You need to find what works best for your setup and run with it.
Neither are really faster, but you have to be careful because i9000 kernels are often incompatible with captivates and your phone will behave strangely if you flash the wrong kernel.

I tend to believe since i9000 roms are always more recent (since att s**** at updates ) they will be faster , but since they were not made for captivate , less 'crisp' in some areas , all this is really subjective to the usage of the phone ..
There is middle ground here , like Andromeda and DRAGON rom , both NON based off i9000 roms neither captivate (i9010 & i9088 ) , using there original kernel you can use any modem you like , with no issues . And since there kernel did not need to be reoriented you dont lose any of the crisp , Andromeda being based of 2.2 is probably the closest to the Captivate source right now , Dragon being the latest kernel released by samsung is definitly the most stable and crisp kernel out there , there is no source for it but neither there is for the latest 2.2.1 out there either , like someone said in this thread what works best for you is what you shoudl use so dont hesitate and flash them all and please dont limit your testing to a few hours days is what you will nbeed to make up your mind ..

i9000 ROMs should give you faster data speeds since the use HSDPA and HSUPA (i897 ROMs use HSDPA but not HSUPA).
i897 ROMs should give you better sound quality on calls since they utilized the noise cancellation audience chip which the i9000 does not have.
As far as ROM speed itself, I do not think that is based on which source is used, but on the actual ROM itself. What I mean is not all i897 ROMs will have the same performance, and not all i9000 will have the same performance.
That is the great thing about ROMs, try different ones and use the one you like best (or switch between several you like to keep it fresh!)

It's not necessarily the ROM that give you better sound quality or faster speed. That is in that is in the Modem and kernel. You can "basically" use any of the modems with "most" ROM's (BE VERY CAREFUL NOT ALL MIX. FOLLOW DIRECTION ON ROM THREAD). JK4 has really good speed and you can use that with most ROM's

Thanks a lot. I use eXistz beta 7 kernel on my cognition 4.2 ROM. Are you saying I can replace the KB1 modem? Are you recommending that I should replace KB1 with JK4. If I do that than probably I should replace my eXistz beta 7 kernel with either speedmod or suckerpunch kernels? One question is: how to do all this from CWM without doing odin back to stock and reflashing the whole stuff? Thanks
Sent from my SAMSUNG-SGH-I897 using XDA Premium App
You can flash kernels and modems right over the rom without going to stock first.
SGS Tools is probably the easiest way.
FYI JK4 is an i9000 modem. Flashing it with a KB1 KERNEL may yield les than ideal results.

What ROM should I get to increase the phones overall performance and responsiveness? I just want something that is very stable and something that will improve my phone in a good way.
Every single rom is gonna be a million times better than stock eclair...for your first time I would stick with a froyo rom as those are easier to flash. Just pick one
oh man.. where to start. Honestly it varies so much from user to user. Your best bet is to hop on some of the threads and read some of the comments.. first few pages and the last few.. try to get an idea of how well the ROM is working for users and battery life. There are a plethora of 2.2.1 ROMs with excellent battery life. The gingerbread ROMs are coming around to having decent to good battery life. But again, it all varies from user to user.
Good 2.2 or 2.2.1 ROMs
Serendipity, Paragon, Phoenix, Ultimate and theres more of coarse, these were among my top choices.
A lot of the gingerbread ROMs can be found in the first page of development.
But please use the search function. There has been multiple threads started with the same question.. about the same topic.
Once you go serendepity, you can't go back. but seriously I tried a lot of roms and serendipity is BY FAR the best!

I tried serendipity and its a great rom but I like a side scrolling app drawer as opposed to the cube effect. I use apex 5.3 (froyo 2.2.1) not to be confused with apex 6.x( gingerbread) because its simply works. The five dock bottom is great and battery life is amazing. And the jk4 modem actually gets me much better reception than the stock kb1. but if you like the stock feel cognition is the way to go

I flashed Serendipity 6.4. So far the first thing that I noticed is that the apps are organized scrolling down, not side to side which is the one thing that I do not liked very much. everything else seems to be very good.
Toad858, which version and where did you the 5.3?
also what kernel do I need?

If you'd like to use your original TouchWiz side-scrolling app drawer, give Cognition a try instead. Cognition is best-known as the 2.2 ROM that tries to stay as close as possible to the original, with a ton of under-the-hood features and fixes (like lagfix), minus the bloatware.
(I can't stand TouchWiz, but still love Cog's stability, so I use Launcher Pro (with its vertical app drawer) instead)
cognition rom is my favorite rom when it comes to stability. and its smooth as ever now.
I think I will stick to serendipity. Now I am trying to figure out what modems do and if I need one to be able to use a kernel? I was looking at Onix Kernel and it says "Since based on i9000 sources, use an i9000 modem". I am not sure what a modem is first of all.

technically, as long as everything works for you as of right now - you're done. You can sit back and enjoy the rom. If you feel ambitious, you can try a different kernel. I dont know what serendipity uses but I found the Onix kernel to be one of the smoothest froyo kernel, available. Thats, of course, my opinion though.
would it be possible to get other keyboards on my phone now? like android or samsung keyboard?

You're set. It's 100% stable and works brilliantly. GB is still a bit flaky.

That's what's packaged in the rom. You don't NEED that modem specifically or need to change ... Unless you're cell signal sucks then check out the modem sticky at the top of the dev section. http://forum.xda-developers.com/showthread.php?t=876391 You do need an I9000 modem because the kernel in serendipity is based off I9000 sources.
What you NEED to do is stop right now. Enjoy your phone and READ everything you can. Once you feel comfortable with flashing and knowing how to get yourself out of bad situations, flash away. No one can tell you which rom is best for you. You're more than welcome to narrow your choice to a few, then try them out or try them all. The key is knowing how to do it and the things that can happen.

Sorry for the nooby question, but i was wondering what a modem is. Right now im in ICBINB with Kf2. I want to flash a froyo theme but it is Kd1 and Kc1 only. Can someone please thoroughly explain to me the differences between modems and if it has anything to do with the firmware. I read that kf2 is gingerbread, but it doesn't affect the firmware. I am willing to clarify my question if needed. Thanks for your time guys!
I don't think there's really a need for a thorough explanation for this, so... A modem/radio is just what your phone uses to access the internet, make calls, etc. You use it for anything that would require a signal.
The performance of a modem will differ depending on many factors, such as location, time, etc. That's why we can flash different modems to get better reception and such. For example, ICBINB comes with a KD1 modem, but I flashed KG4 on it, because it has better reception and data speeds in my area.
Here's the link to the KB5, KC1, KD1, KF1, and KF2 modems (CWM):

Here's the link to all the modems in Odin format:

I hope this helps you! Be sure to read the directions carefully!
Oh, i think i somewhat understand it now. Just to clarify, changing modems to test signal strength won't cause any damage to me phone? Thanks man appreciate it.
flashing a modem will not cause any damage to your phone. the performance of each modem is dependent on your location, so what i do is keep all of them on my sd card and should i lose signal, i switch it out and i usually find one that works where i am. modems are very useful in different situations.
Oh, perfect explanation! Thanks guys for the information!
No problem!
So far, I think KG4 gave everyone a slight boost in signal. Swap out your modems and go crazy, but just a heads up that KG4 is pretty awesome. Also, KB5 is supposed to have SMS problems and such. You can easily find the problems of the KB5 modem on Google, which were fixed in KD1.

If kb5 is your modern of choice, to fix the mms problem, remove the dashes on the phone number you are sending it to. Make sure it is only numbers in your address book. Of that doesn't work, add a 1 in front of the area code.

Yeah, it's most often referred to as the radio but, for whatever reason, they call it the modem in these SGS forums.
yea, the name changes, depending on the phone. its all the same reference
Might be Samsung's fault. They named their radio/modem update files modem.bin.
Im using drhonks KG4 2.3.4 on my SGS4G and for some reason the tmobile wifi calling app volume is very low. Meaning, I cannot hear the other person, although they can hear me very well. Anyone else have this issue? I searched around xda but couldnt come up with anything conclusive.

Thanks but no thanks. KG4 is very stable and works best. I tried KH2 and KG6 as well among a myriad of others Including Bali which bricks my phone. KG4 provides the most stability and best benchmarks for me.
I dont know how using a stable kernel for my device makes me a noob but to each his own.
Also since you are going to call people noobs for using Kg4, you should change your sig file. It still says you use KG4. I wouldn't want you to be associated with the plebs.
EDIT: KH2 does not fix this problem. thought you should be aware of that as well.

Benchmarks should be about the same for all of them. For some reason, Samsung Adrenaline Shot v6 isn't giving us the proper scores for Quadrant on the KH2 kernel. The smoothness of the phone and the tests run Quadrant are very similar to the KG4 kernel. AnTuTu gives a similar, if not, better score.
Bali kernel would obviously soft-brick your phone. It's a kernel meant for Froyo, not GB.
As for your WiFi volume, that's normal on all GB ROMs. There has been no fix for that yet.
Honestly, using any build on this phone is fine, except for KF1 and KF2. You would be crazy to use those, lol.

BTW, it says I use the kg4 kernel. The hacked voodoo one. NOT KG4. I use audiophile.
Considering that we all have the exact same phone, I find it *very* hard to believe you're getting better performance and stability out of KG4 than KH2. I just made the move to KH2, and I've noticed several subtle yet substantial improvements over KG4 -- including wifi calling volume. The *ONLY* instance where I have a problem with wifi calling is in a situation that will never arise for me in real life:
When wifi calling is on *and* you're paired to a BlueTooth headset or handsfree kit, the other party hears an echo of their own voice *when you call them*. Incoming calls don't suffer from this affliction, and calls in both directions are just fine if you're not paired to a BT audio device.
I guess it's also worth mentioning that I avoid "deodexed" roms/releases like the plague, and the KH2 I'm running is the raw leak that krylon360 got his hands on. I really don't know if that could or would make a difference in the wifi calling issue, but I know for certain that I've run into less problems and quirks on odexed roms and releases than I have on deodexed ones (not to mention there are GOOD reasons for odexing (that far outweigh the primary reason for deodexing, which is themes), but that's not for this thread).
As far as the condescending attitudes of some of the people here, I say just shrug it off. When someone's a **** to you, take a few minutes to look through their posts and topics, and often, you'll find they're a condescending **** to most people, not just you. I usually only read 4 or 5 words into airfluip1's posts, and often, that's 3 or 4 words too far.
Oh, and airfluip1: Why do 'noobs' insist on running kg4 kernels on their kh2 roms when drhonk released a kh2 kernel for it?
P.S. -- If you can recover from it, it's *not* bricked. Flashing a froyo kernel over a gb rom will definitely send you into a bootloop, but that's not a brick. A brick implies just that: your phone is now dead and useless, you may as well slap some mortar on it and use it to fill a hole somewhere in your house.
