Comparison of Different HSUPA i9000 Modems in Captivate - Captivate Q&A, Help & Troubleshooting

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.
thanks all!

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...

next flash: Darky's or Insanity? Recommendations/endorsements?

have tried just about every custom out there with the exception of insanity and darkys roms.
Pondering both for my next flash....anyone have recommendations for which they prefer.
all comments welcome and encouraged but would doubly appreciate feedback from those who have used both.
Several threads like this have already been locked in the past 2 days. Why start another one?

I apologize if i am in error. I didn't realize there was any problem asking for specific feedback or recommendations on a particular rom or roms.
According to the forum rules what is wrong with my post?
http://forum.xda-developers.com/announcement.php?f=263#td_post_81
If i am in error please delete thread.
Just look through both Dev threads. That will give you lots of information on what people like about each one. And if you have flashed about everything under the sun flash both because chances are you will eventually.
I was just pointing out that these kinds of threads have been getting closed left and right the past few days. ROM recommendations are really very subjective. No one knows what your requirements are and how a ROM will fit them. What works for one will not necessarily work for all others. And the ROM Dev forum is really a better place to be looking.
I will add that anything i9000 based like Darky's has plusses and minuses. The plus is that you get great HSUPA speed. The downside is you get the EU flavor and features that don't work. Spelling of some things is EU, options for FFC are there but don't work.
There are many other details.... I just hope for the Captivate source/official release soon so we can get a true captivate 2.2 kernel and tools to build from.
Assonance all the way.

1. I was asking for feedback most specifically from people who has used both roms. This wasn't a Whats the best rom ever thread.
2. The developer thread definitely would not have been a place to post this and in my extensive use of the forum and reading and re-reading of the rules i fail to see how this post violates them. So again if i am mistaken...my apologies to all and i beg on the mercy of a mod to just delete the thread. (i have read both threads for the two stated roms....was hoping to hook more direct compare and contrast from users who have played with both.

lol have used assonance so i was just looking for feedback and comparison between darkys and insanity.
flashed darkys earlier and its a pretty rom but don't think i am liking it any more than Doc's or Chronus so i may give Insanity a run before going back to chronos or doc's.

hey thanks for being one of the first to post feedback thats actually relevant =)
i had went with darkys and what you said is right on. I think i still prefer Chronus Rom and Doc's most recent so will probably flash back to one of them but may give insanity a quick trial before.
So Darky's rom ported over to the Captivate as seen in this thread switches what exactly to make it Captivate-specific...just the modem, kernel and a few GPS-related modifications?

appreciate the link. had already trialed darkys...nice but i went back to chronus 2.0 for now.
funny i had just flashed it when i saw my other favorite rom (doc's) posted an update.
I'd go with the non-racist sounding one.

Personally, I am partial to the breaded chicken sandwich with cheese and bacon. It is quite the treat, and you should only eat one per year to avoid heart conditions, lol.
On topic... I've been looking to start venturing into custom ROM's on my Cappy, but I am tempted to wait and see if Cyanogen ever devs their 6 or 7 for Captivate now that they are dev'ing for Nexus S...
I have used pretty much every ROM out there, even the ones that do not make it to the Captivate forum and so far Darkys is my usual go to ROM.
For some reason, when selecting the Gallery images, it is the only one that does not lag before going to the zoom in and out window.
I am not using Lag fixes btw with any 2.2.1 rom.
have had a chance to play with both....no more recommendations needed.

[Q] Modem?

Hello, as you may realize this is my first post on the forums, and I have a couple questions.
I'm currently running Cognition with the Firebird 2 kernel on it, and I've been learning things about modems recently.
To clarify things however:
What is a modem? I'm under the impression it is the "driver" that allows the phone to contact the world, but please tell me if I'm wrong or elaborate.
And,
What, by people's experience or knowledge, is the best modem for me to use with my Firebird 2 kernel? Currently my phone is running JL1.

As far as I know, modems have an impact on data speed, phone quality, GPS and phone signal. Everyone has different opinions on which modem works the best for them, but generally I see that a lot of people like JK4 or JL3.
last week there was a thread here on xda captivate that will answer most of your questions on modem / kernel... I don´t remember where exactly but it´s nothing that a little search won't find!

I had an issue with JK4 that all my system sounds were really quiet, almost inaudible (even at the loudest setting). I've had great success with JL3 though.

[Q] Which ROM is right for me?

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

[Q] Increasing in call volume?

As the title says, how do I do this? (is it possible). I'm currently on serendipity 7 and I love the rom. Problem I have is the same prob I have with all GB roms, and most I9000 roms, (I'm an I897), call quality. Through trial and error I have found that jl2 and jl3 modems offer the best quality for myself and the people I am speaking with, however I would really like to increase the volume in my earpiece. It's ok, but it's a lot lower than any kb1 I've used. I have the volume all the way up, and sometimes it's a struggle to hear the person I am speaking with. I have sgs tools and I've investigated in the volume controls of the audio section. Problem is there are so many options for tweaking and I don't want to just go in and start increasing numbers that I don't know what they're for. Any guidance on which numbers I should increase to hopefully solve this issue? Also, galaxy tuner gives me issues, mostly just not working, so I don't think this is an option. Any advice would be greatly appreciated. And yes, I searched this before posting, and didn't find what I was looking for.
There's a Serendipity sticky in this forum for exactly these kinds of ROM-specific questions. Please use them. <---Smiley to avoid being characterized as a "****" again.
Not calling you a ****, but if you read my post, my question isn't rom specific. It's referring to all GB roms and I9000 roms in my experience. Can anyone else help?

In-call volume is a known Cappy problem that is fixed in many of the custom ROMs available here. Some do a better job than others, but it is a ROM-specific issue.
I say try a rom that is based on kb1 the official froyo build. The kb1 kernel had the proper drivers fire the audience chip used in the captivate. The I9000 uses a different chip so all I9000 roms will not have the use of the audience chip for noise cancellation.
Roms like cognition and fusion might be worth a shot.
Thanks studacris. I actually am running cog 4 on my other cappy, I just love using my gb cappy more. Just hoping there was a way to get same/similar call volume as my cog phone. So is tweaks with sgs tools useless with the gb/I9000 roms? Are you the captivate creator? You know everything bout this phone! Lol!
Sent from my SGH-I897 using XDA App
Lol. I have no idea about the sgs tools tweaks, I get about 1 call a week never really looked into it myself.
I don't blame you for wanting gb it's pretty sweet, I haven't gone to froyo since I made the jump. If you want audience chip support and gingerbread goodness keep an eye on this thread http://forum.xda-developers.com/showthread.php?t=1125596
This should be in the sticky, thread closed.

i think this will help quite alot
I'll take a look at it and see if there's anything usable for my CM7 fix. But I'm guessing this was pulled from a TouchWiz ROM? From what I can tell at first glance, CM7's gps does not use a lot of the stuff found in the rar you posted. Maybe some stuff can be integrated into CM7 directly, but I don't know enough to incorporate it into a fix after the fact.
Maybe someone else can help take a look, but AFAIK I can't use most of this.
Hopefully it'll help out TW-based ROMs.
aosp 4g rom for sprint that has source http://www.androidpolice.com/2011/0...urce-code-before-the-phone-even-hits-shelves/ might have something there for, might not. Phone is kinda galaxy s ish
I'd hate to break it to you but, the virgin mobile and the bell vibrant are simply rebranded i9000's using these files would be like using i9000 gps files. We wont be able to get 100% fast and accurate gps until our vibrant (sgh-t959) gets its own leak, if it even exists. We won't ne able to get gps with files from even phones that look identical to our phones (t959d) because of their radio bands. Our vibrants are the only galaxy s models (other than the t959V) that get 3G signals on 1700mhz bands. I think to have the 1700 bands, it requires a slightly different hardware radio, this slight difference allows the i9000 gingerbread gps (from jellete) to work but leaves all other files from the i9000 unusable on 2.3.

I also hate to be negative here but it may be that the T-959 is no longer being supported (evidence being that Sam firmwares source only seen the froyo update in the system)
I think that the obly way we will see a spot on GPS is if someone takes the time to hack, crack, and reverse engineer the files we do have and try to figure out where certain things go.
Maybe ... just maybe since cyanogen got a job at Samsung he may be able to convince them to opensource certain things in the better interest of android.
Just a thought lol
