Hello my fellow XDA members!
So I use the SGH-I897 as my daily driver; I've experimented with many different roms and so far my favorite is the slim bean; however I would like to hear some opinions of modems that are currently being used; favorites, are there certain modems I should be using w/my particular phone now, etc.. Thank you in advance for everyone's time and insight! Oh and I researched what modems do a little bit, but some more detailed info would be great as well; Thanks again everyone!
I'm pretty new to this scene; so if there's anything that I should be doing please let me know as I do not want to upset any of the senior members!

Modem is basically your signal. If your internet speed and your calls are fine, there's no need to change it.
Also, it is quite hard to suggest modems as they will have different strength in different area so when you get bad signal and such, you have to try a few different ones.
If your signal strength and data connections are good there is only one other reason I can see that you would want to change your modem. That would be if your having issues with GPS signal. Of course the cappy is notorious for being less than stellar with its GPS but I once had issues with signal(turns out it was my carrier not my phone) so I flashed a couple different modems. One that I tried completely broke my GPS until I flashed back to what I started with.
That being said the modem you currently have installed is what works best for me and based on various threads and posts its seems to be a favorite.

Hi everyone -
I'd like to know the difference between each HSUPA i9000 modem that has been tested in the Captivate
I think it would be good to know what the strengths are, when / where it first emerged, and known issues with it.
If you post below I can keep this updated.
I'll start:
JG8 - i9000 Eclair ROM. Works for enabling 850 band for those launching a reorientated kernel. Do not use with Froyo.
JPP - i9000 Froyo ROM.
General principles:
- don't mix an i9000 modem with a cappy kernel or visa versa
Known issues with using an i9000 modem:
-bluetooth voice quality
-wired headsets don't work on mic
thanks all!
bump, i was just gonna ask the same question
The problem with asking questions like this in the Q&A section is that all the developers that can answer it well hang out in the Android development section and never come over here
And people wonder why there is so much spam in that thread.
C'mon guys, help me out, and lets prove that we don't have to start technical question threads in Android development in order to get an answer.

Can some1 tell me which taste batter? Orange or lemon?
Try it yourself znd u will know!
yeah real helpful. is there any difference in frequency support? can bluetooth work corectly along side hsupa yet?
which is the most recent? jg8, jpp, jpm? does one need to be installed before the other? are there any other known problems? battery drain? instability? ect?
someone must know

Haha funny! I thought of doing that myself but the problem with n=1 is that all you guys would get spammed with my own quirks. Hence why I didn't add the point about JG8 FC'ing on me under JG8- most people haven't said that - so I just have a weird bug with my location/hardware/who knows what. I'd kinda be spreading disinformation if I put it down as "truth"
Anyways, anything that anyone wants to contribute I'd be more than happy to include. I think it would be helpful. THanks.

As you can see, I have no idea which one I should choose. This information is embedded within 1000's of pages of material and a good 30 minutes to an hour of reading didn't get me anywhere useful.
I had issues with JG8 FC'ing. Obviously not the case for everyone but in my circumstance I'm looking to try an alternative.

Well the one problem I find with every HSUPA modem is the Bluetooth quality sucks...Since Bluetooth is more important for me I don't use them anymore...Upload speeds are nice but I don't really need it...

You should just read through all of the Roms on the first page or two of the Dev section. Look at which ones have the most posts/replies under them and check them out. Evaluate the features list and browse through some of the more recent comments pertaining to them to get a feel of how well each one works and what they provide. Ultimately, which rom to use is entirely dependent on what you're hoping to get out of it.
What do you want it to do/not do?
Why are you looking to move away from Cog?
They all have their own ups and downs, it all depends on what's right for you.
I'm running Cog 2.3b6, myself, and thinking of upgrading to Cog 3.03. For what it's worth.
I used to use cog as well. I decided to change roms due to what I perceived as a rom problem, only to find out that it was more and likely a modem problem. I had really poor call quality and overall signal degradation.
I decided on the now no longer supported assonance and albeit all the "bells & whistles" of the newer roms, I do not have any interest on flashing a new rom. I have since flashed the speedmod kernel, which drastically helped with my battery issues and will flash a diff modem.

Went through a number of ROMs and settled on FireFly with SpeedMod kernel. Smooth, fast (no overclocking), good battery life, GPS fixes, haven't run into any FCs in over a week now... just a very solid performing ROM.
I would recommend serendipity but phoenix looks like the next best (never tried it though)

I'm not necessarily looking to move away from Cog... just wondering if there were any "runaway winners" that I should consider also. From the posts so far it sounds like there may be several worth considering.
What I'm basically looking for is an overall combination of speed (without overclocking), stability, functionality, and battery without any of the factors being stressed/tweaked to the extent that it significantly hurts any of the other factors (i.e., I don't want extreme speed if it means an unacceptable hit on stability or reduction in battery life, etc.)

There are a ton of ROMS out there for the Captivate and I've tried quite a few of them. However, I'm not sure what the differences are or which one is right for me.
I've heard of:
Cognition, Perception (by Designgears)
FireFly, Phoenix (seems like these are by the same person)
Serendipity
I haven't tried Serendipity or Perception, but I've tried the others I listed. Various ROMS say they are based off of KB1 and JP6 (I probably have these wrong) as well as various other 3-letter names. I'm not really sure what these mean, but I think they relate to the ROM being based off of Android v2.1 or Android v2.2.
Here are a couple of things I'm looking for in a ROM:
Battery life is important to me. Most roms so far have been very good at this so long as I change the Wifi sleep policy to "Only when plugged in". If WIFI is on permanently, my battery life is crap.
I prefer a good theme. FireFly's theme is pretty good. It looks great and has nice window animations.
Must be at least Android v2.2. Gingerbread would be awesome but not a requirement.
Stability. Specifically, all phone/hardware features need to work and there should be minimal bugs. For example, using CM7 for Captivate at this point would be out of the question since it's still so young and I've heard it is unstable/buggy.
Based on what I've tried and my requirements, Cognition probably isn't going to be an option. The last time I used Cognition (when it was v3), it wasn't themed and was just an optimized version of stock.
Firefly, Phoenix and Serendipity all seem to be the same thing but with a slightly varied theme. I'm most confused by this. What are the differences here? If there are technical differences, I'd like to know those too. I think each are based off of different firmwares, right?
Thanks in advance for any guidance.

This is not helpful at all. This is what I've been doing.
I need someone to go over the technical differences between my choices, since I don't fully understand them myself. I have yet to find a guide somewhere that talks about the technical differences between all of them.
Can someone else provide some helpful input?

The best place to find any info abt any ROM/kernel would its OP. Try looking there.
Plus there won't be so much use of anyone compiling the differences 'cos a new version would be out every now n then. This is one of the reasons why there is no such thing.
Rather than asking for something generic like this, u could ask more specific questions like say. That way u wud get ur answers sooner.

1. wifi always has phone searching for it all time the screen is on. So keep it in when screen turns off, or the option u selected.
2. Themes are personal choices. Based on the ROM u choose, u can select theme of ur choice, or make a theme urself. There are guidelines posted.
3. Most ROMs now are 2.2.1. Would be mentioned in the OP.
4. Custom ROMs cannot guarantee that. Devs take all care and iron out issues when they find or when someone tells them abt them.
Check out a few ROMs and settle for one that suits u. And if u plan on putting on custom ROMs, don't bother on keeping ur hands clean. I think I flashed more than a dozen different ROMs before settling for what I am on now. And since I now found what suits me best, been sticking to it.
This is the normal process most people follow here.

Unfortunately, mcord11758 and diablo009 are right.
The differences are minimal, and you need to research each ROM. The very basics are.
MOST roms right now are running Froyo 2.2.1. Some are still 2.2. The JPY, JS3, JS5, KB1(Stock 2.2) Are, for lack of a better definition, are build numbers.
What you'll need to do is, quite frankly, read up on one that has your interest, flash it and if it doesnt work well for you try another. Each Captivate may respond to a ROM differently to the ROM/Kernel/Modem combination. So you literally have to try it
first of all I installed MIUI rom a week ago ..
it took me 2 hours to just do that..
then I figured out that people are flashing thing called "kernel' which apparently makes phone faster. So i flashed glitch kernel
then I noticed people talking about modem..
what does this modem do and what is the best modem for miui rom?
thanks in advance
I am a super newbie as well.
But I think people change their modem because sometimes the phone signal (3G/2G or whatever) is just too lower than the usual.
It seems to be different phone to phone. But if your phone signal seems normal, you don't need to anything (I guess )

Modems are the software that establishs and controls your phone, data and gps signal. Some modems work better in certain regions or with certain carriers. Some may be best with gps, or shine at data transmission. Also if your phone supports the 850 band you will need a modem that supports that. Getting the best signal you can is important because the sgs can burn a lot of battery life seeking and finding a solid connection.
Modems are painless and quick to flash via recovery, so it never hurts to try a few out to find the best for you and your usage.

Thanks for this educative info.
When we think to root, we should know some know hows to avoid such issues.
I'm currently switching up ics roms and kernels to see which works best for me but I do not understand modems so I need some help here. I saw jk4 on the map close to me. I live in jacksonville fl and commute all around the city and west of jacksonville daily I was wondering which ones to try out.

Just start downloading them and trying them, giving them about 2 days before you decide if you like it. Several factors to consider are call quality, signal strength, battery life, and GPS reception. Since your using ICS roms, you must use the modems packaged as CM7/MIUI. You try using something else and it won't flash.
Look >>HERE<< for all the modems you would ever want to try. (FWIW, I like BVJWW2)
Like mrhaley said, there are a variety of things that affect it. JK4 worked great for me when I was in Florida, so I would start there. JW2 is nice also, but it seems like people can't hear me as well with it.

Better battery life will happen if it gives you better signal strength in the areas you spend the most time.

Hello guys, a few days back I flashed teamhacksung's CM9 ALPHA for Captivate (BUILD 17) on my wife's phone, but she has told me that her apps are not syncing outside of a wifi connection.
I'm thinking it might be something related to the modem.
So I'm looking for any advice on which moden should I load, considering we live in Venezuela? Any tips?

Someone listed the "UGKC1" modem in use in Panama. You might consider UGJL2 or UGKG3 also, near by. Search "soggy cashew captivate modem" and check the map. Update your own listing if you find something that works.
