[Q] A few questions from a newbie on the fence on what to flash.

So after 2 awful years with a first gen Blackberry storm I decided to make the jump to android with the captivate. Originally I was holding out for the Nexus S as I really wanted a vanilla Android experience (I have a deep hatred for bloatware) but unfortunately around where I live it appears Verizon and AT&T are the only ways to go if you want any sort of decent coverage.
Anyways, I've been doing a bunch of research and watching videos the past week I've decided to flash either Perception (build 8) or Cognition (probably 2.3b6) and am leaning towards P8 as of now. I am wondering how much of these ROMs is vanilla android.
I realize from what I've read/watch that the touchwiz launcher is removed in both of these roms as well as the AT&T bloatware, but is much of the other base applications such as mail, media player, etc is still the samsung apps?
Basically, I'm wondering how close to vanilla android will the launcher/interface be with one of these Roms (obviously the roms include some additional apps, I guess I mean just the basic functionality/interface).
Also, is there a major difference between running a rom such as Perception or Cog opposed to simply unlocking/lag fixing and removing bloatware as far as general speed and lag. I know these roms are using leaked Froyo firmware opposed to the stock eclair I would have if I did not flash, but I'm curious how big of a leap in performance it is.
Thanks for the responses, hopefully my questions make sense, my captivates not coming till Monday (bought it through Amazon wireless) and I've been reading random android forums seemingly nonstop.

I always click thanks button before quote button now! Oh well.
I know cognition has twlauncher, not sure about perception (I don't remember..)
All custom ROMs have bloatware removed at your convenience. I'd say froyo is definitely faster. Either voodoo lagfix from xcal's kernel or lagfix from SetiroN's kernel gives a big performance increase. Cognition is based on a captivate rom whereas perception is based on an i9000 ROM.
No ROMs right now provide complete vanilla experience. I believe I read it somewhere that the Galaxy S line devices use rfs loops whereas usual android uses ext and this causes a problem for devs to port over vanilla android or other skins like HTC Sense. (Someone correct me if I'm wrong?) As of currently all the stable ROMs are based on froyo leaks with captivate, vibrant, or i9000.

I've tried many variations with stock roms, rooted, lag fixed etc. I currently use the cognition rom, latest one. It is much faster and better than the stock. It has voodoo lagfix built in. I haven't tried p8, because I like the cognition so well. I definately recommend giving cognition a try. I was also going to try Axura, but haven't for the same reason.

Try Assonance or Axura. IMO they're more vanilla than Cognition or Perception.

Thanks for all the info all.
Honestly I haven't even looked into assonance or axura, are they as stable as Cog/Perception?
quarlow, when you say you use the latest version of Cog do you mean b6 or b7? I know b7 just came out a day or two ago. I'd stick with the non-oc versions, seems like they tend to have alot less issues from what I've read.

My bad, I'm using b6, I didn't know there was already another version. Yeah ... I don't do the oc thing. I have a hard enough time between charges without adding oc. It really is screaming fast already.

I haven't really tried Cognition or Perception, but I've tried both Axura and Assonance and both ROMs seemed really stable.

ah jeez, now that I've been looking into it, I think I'm gonna go with assonance. Seems like its alot more stable than either Cog/Perception from what people are saying.
Just curious though, how fast/smooth does it run? Compared to stock and/or Cog/Perception?

Axura gets my vote
Stable and fast without needing to overclock
Need to use google voice for vm notifications though

All 2.2 Roms are smooth and fast compared to stock. Assonance will be your most vanilla (least amount of Samsung apps). Auxura is heavily themed and no where near vanilla. Plus it's based off of leaked Vibrant and I'm not a big fan (though I'm definitely in the minority here). Personal favorite is di11igaf's Rom. It is also heavily themed, but all themes can be changed and it works the best as far as functionality (my opinion, of course).

I'll second this. di11igaf's ROM is the most stable and fastest I've used. It might not be "vanilla" since it is themed, but the dark theme on it is so nice. You'll like it. I've flashed this for friends at work and they all love it and they have no more forced close issues, whereas they complained frequently about FCs with Cognition.

If you don't mind beta software, CyanogenMod is the best. It's actually built from AOSP code, with only Samsung drivers. All the other custom roms are just modified versions of the stock rom/leaked rom.

I run perception 8 with gingerbread theme and vanilla apps injected in place of sammy ones... so I kinda feel like im running gingerbread

DO NOT FLASH THAT TO YOUR VIBRANT!!!
I just helped a guy Odin back to stock cuz he flashed that to his Vibrant...wait until Vibrant Devs port it to the Vibrant

Porting I9000 roms onto the Vibrant isnt as easy and clear cut as it seems. Thats why Eugenes first 2.2 port was full of bugs

waiting..... i am very excited for this rom

The captivate has this rom too

Its really pointless porting a 2.2.1 rom at this point. First, its honestly not much faster. Second, we're really close to have an official 2.2, maybe even gingerbread. We'll more than likely have gingerbread before anyone actually ports a fully working, bug free 2.2.1 rom based off i9000 code. You might get a VERY minor speed increase, but of course with the trade off of having tons of bugs. Not worth it in my opinion. Speed AND stability is the way to go. Not speed and bugs.

Exactly, and the only reason I brought Ragnarok to the point I did was because I had already started it. I did, however, learn a lot in the process. And I finally figured out how to fix the dang gps - even so, it is nowhere near a daily driver - more a curiosity.

This is true, if we have a ported 2.3 there is no point of having a 2.2.1
But I had in my i9000 a 2.2 ROM version and when switched to the one of Darky (2.2.1) I could see a real change in speed. (I had before Voodoo). Anyone could notice the snappiness of the phone!
It is pity, the devices have so small differences in hardware and it is so difficult to port ROMs. If you notice the Galaxy S forum is full of custom ROMs and mods, plenty of them. Aditionally long time ago there was unofficial and then official FroYo...
Waiting....The only reason I got the Vibrant is the AWS ... (and it still needs a mod for the FFC)

Yeah, I had the same curiosity 2 weeks ago. I had 2.2.1 running on my phone. For the most part it ran fine, but would randomly get tossed into a bootloop. And when I say randomly, it was extremely random. There would be times my phone would run for hours, other times it would bootloop an hour after boot, 20 minutes after boot, or immediately after boot. lol.

If you read the ragnarok thread there is a possibility that the boot loops are triggered by signal strength. Still, it would require capping the strength to stop it.

Ok so I am understanding (sorry still learning the lingo here and there), The I9000 2.2.1 is not that great but the 2.3 Gingerbread from the NS is possible to be ported to the Vibrant right?
If so then sombionix, may I suggest you dont bother your precious time with all these leaked releases (JL_x's) and only work on the 2.3 NS port. I have used a few of your roms and they are sweet, I can only imagine what it will be like with all the JIT patches in 2.3!

[Q] What is the best Captivate ROM?

Which ROM is the best for the Captivate?
I have been running Assonance 5.2 since I rooted, but have recently been looking for something more. I have heard good things about Paragon and di11is ROM. I need full GPS functionality so ROMs without it are a dealbreaker.
Let the discussion begin.

I personally like darky's a lot. The most recent versions have added easier support for the captivate but may still need some work to get working. I love it though.

Andromeda seems to be the overall top at the moment. I know we're supposed to say "its preference" but no bull**** its the most stable rom and the quickest.

Fixed that for you, seriously just try them all based on what theme you like and what kernel features you need.

They all are good, some are better, all have bugs. Anyone who says other wise is lying to themselves

I really like serendipity. fast, stable, awesome.

ive tried cezars, cognition, and firefly out of those i liked cognition out of the box but loved firefly after some tweaks i think if u want stable go with one of the rogers 2.2 based roms

I've found the same, big fan of Firefly right now, I used the firebird kernal with ADW launcher. It's about the best my phone has ever run.
The reality is that they all work a bit different on different phones, your going to have to experiment with a few to find the one that makes your phone happy. I understand how this seems strange, they should all be identical ( it's the same hardware right? ) but it's not so, for some reason they behave differently.
Good luck finding the combo for yours.

Check my signature. Results speak!

I've been using Darky's on my Captivate, and it's been running amazing so far.

How come no one mentioned Pheonix rising?! I've tried cognition but this seems better stable and fast. And With the GO launcher my life has really changed.

Andromeda is really great. Can't say enough about it. turned my cappy into what I thought it would be when I bought it.

Yeah I'm a big Andromeda fan too. I also like Perception with the latest Speedmod kernel. I was running Paragon RC3 and got amazing battery life from it but overall it was kind of choppy and not as smooth as Andro and Perception/Speedmod. If I was going on a long trip I would flash Paragon and pop in my 3000mA battery. But as my daily driver I like Perception and Andromeda.

Keep coming back to Cognition 3.02. Just flashed Firebird Kernel because I wanted to enable HSUPA and Voodoo Sound. Went though I9000 JL3, JK4, and JK3 modems. In call volume on most I9000 modems are pretty low, but that can be fixed. However, I was having GPS problems with every modem I flashed, BUT, I came across the KP1 modem and it's working very well. Good call volume without tweaks, GPS lock in 10 to 15 seconds (within 10 to 15 meters accuracy), and solid upload/download (~1500 - 1700 kbps download / ~12000 kbps upload)
My phone really doesn't seem to like I9000 ROMS, though, and I've tried mostly all of them. Serendipity seemed to run the smoothest, but I didn't get good GPS performance so I went back to Cog 3.02, but that was before I came across the KP1 modem. I'll probably give Serendipity another try with the KP1 modem before too long.
Just like everyone says, it's all up to personal preference. I've had my Captivate for six weeks or so, and I'm starting to find out that the ROMs offered by the great developers who post on XDA are fantastic in and of themselves, but they can also be great starting points for you to find out what works on your personal device. Different kernels which support certain lagfixes, video and sound enhancements, and different modems are available so that each individual can find out what combination of ROM/Kernel/Modem works for them.

I haven't had my Captivate very long but I've flashed Cognition, Andromeda, and Serendipity already. The best so far for me in speed stability and appearance has been Serendipity. Just my opinion as everyones Captivate is different.

Serendipity bar none!!!

>>In call volume on most I9000 modems are pretty low, but that can be fixed.
How? By switching to a different modem, or what?
It would be nice if there were a chart that listed modems and kernals, showing the features in each and their compatibility with each other.

noticible differences between 2.3.4 and 2.3.3?

So, I'm not sure exactly, but I would think that 2.3.4 would iron out a lot of the bugs that 2.3.3 had.
Is that so? or is it a minor upgrade?
Regards
Smith

That is what the consensus around the forum suggests; 2.3.4 is much more stable and smoother.

I have tried 3 of the i9000 gingerbread roms that were made for our captivate and did notice the going from a i9000 2.3.3 to a 2.3.4 did make a difference in overall quality and just seemed better. I now have switched from the i9000 gingerbread 2.3.4 to the new kf1 gingerbread made for our cappy and I have to say I am impressed, it seems as smooth as the i9000 2.3.4 and now just needs some small tweaks to get cwm working and then some themes made for it. But right now it works pretty damn well right out of the box with AWESOME call quality. And the 3g is okay since that is all we can get with the kf1 modem on the stock kernel but it doesn't seems to be too bad as compared to the better speed of hsupa+
Another note is that flashing it right now via DGs 1click gingerbread is VERY EASY.
Another note though for you either way is that no matter what you are using Odin and flashing bootloaders (i9000 with its gingerbread bootloaders and the newest captivate flashes it own set of bootloaders that keep the same stock button controls for recovery and download modes). There are many more options as of right now as far as themes for the i9000 gingerbread roms. Good Luck

That's a crock. Lots of people help out like that. The problem is many more just blow through the door, start posting (often with crappy titles that inhibit the search function for others) without doing a search or even a scan of the Sticky titles and expect to get personalized service from what is basically a bunch of good people volunteering their time and expertise for free. That was very nice of Rock Ratt, but he's hardly unique in here. If people came in and exhibited even a slight amount of consideration for the forum instead of only caring about themselves (how many threads on 3e verification do we need?), this forum would run a lot smoother and members like me would have a lot less to say about it. Press the thanks button when appropriate and don't be afraid to donate to those who supply the bits and pieces that make our phones work better.

[Q] Hello there, can someone here recommend me a ROM please?

I'm a new user here (yes...I read all the faqs) but I'm still not fully aware of the ROMS available and their respective benefits. Didn't really see any threads that helped me in the captivate section.
What I'm looking for most is excellent battery life and signal (if that's possible). I tried Cognition and it seemed alright for a bit but then my signal became spotty and battery worse (not sure if it was the ROM or my phone).
If it helps: I'm on stock froyo (on Rogers).
I'm not really interested in a multitude of features that may overload my phone, I'm a minimalist.

You could always try flashing a different modem if you're having issues with signal.

I've found Continuum 6.1 to be the best operating gingerbread ROM for my phone. This after experimenting with pretty much every other ROM out there. Battery life has been good.
I'm a moderate user. Mostly sms and music. I get 2 full days out of a charge when running the music app 2 hours per day and sending 20 or so texts.
This is purely anecdotal. My wife's phone got poor battery life out of the same ROM. Just going to have to try one at a time until you find one that works well for your phone.
Good luck.

Are you looking for a ROM based off gingerbread or froyo?
I would recommend a froyo based rom for stability, serendipity 6.4 treated me pretty well when i first started and now i'm on fasty 2.3 which is pretty good too.
If you live in the northeast USA then i would suggest JW2 or JV5 for modems.
(See this link for modem options and good discussion on the topic, http://forum.xda-developers.com/showthread.php?t=876391 Ignore the poll, its out of date.)
If you want to try out the tasty goodness of gingerbread then i suggest trying serendipity 7 or the leaked "stock" 2.3 ROM thats been out for a month now.
Keep in mind that you are more likely to find bugs and random problems with gingerbread ROMs since most (all?) of the current ones are not based off of the i897 captivate ROM but the i9000 instead.

You're going to get a multitude of suggestions being that everyone has their own favorite. What works for some may not work for others. I personally have found that I can get healthy battery life out of most any rom I flash using an OC/UV app. Usage and location has a lot do with it as well. Your best bet will probably be to try different things and explore on your own til you find what works for you. Luckily there are tons of people in these forums who are eager to help and lend advice. I certainly wouldn't have learned as much as I have without them.

Stability and battery life = serendipity 6.4.
Stability on gingerbread = serendipity 7
Awesome features(but you don't want these based off op) = MIUI
Sent from my I897 using XDA Premium App

For a froyo based ROM ill easily agree serendipity is the way to go
And look into the onix kernel
For a gingerbread ROM try either continuum or apex, but avoid the betas just use the stable releases
And look into the talon kernel
Both kernels I recommended are by the same dev and are capable of overclocking (which you don't seem too interested in) and undervolting (this will help with battery life)
If you want to overclock stick with 1.2 ghz, anything higher is usually unstable but you could get lucky, 1.2 is safe though.
For undervolting read around for the guides to oc/UV. Make sure you have a way to wipe your voltage settings if you mess them up (should be built into onix's recovery, and its definitely in talons recovery)
No matter if you choose froyo or gingerbread and whether you use any of my suggestions above, look into the gingerbread bootloaders (try to avoid the i9000 ones, even though they work on the cappy they weren't made for us) I don't know if there are rogers bootloaders for gingerbread but I know the att ones work great and you can probably change the logo later.
The gb bootloaders are obviously required for gingerbread roms, but will work with froyo roms as well, so you may as well grab them now.
As for signal read into modem flashing, make sure you get cwm2 flashable modems for cwm2 recoveries (like onix) and cwm3 flashable modems for cwm3 recoveries (like talon)
Your best bet here is trial and error
Jk4 seems to be a good fallback modem for functionality (no frequency dancing issues which can cause roaming or no signal) but I'm not a fan of its signal strength in general or battery life, personally I like kc1 and zsjpg depending on what region I'm in.
Anyway I hope this info helps

Try them out for yourself. We can give you what,works for us but might not work for you. A search would have told you this. Thread closed.
