I am a n00b humbly trying my best to read as much as I can to be able to flash my first ROM. There are some great stickies which tell me how to flash and allow me to skip the impossible task of reading the thousands of pages on the subject. So far I've rooted and installed ROM Manager and CWM Recovery, and thanks to some consolidated stickies posted by this great community, anticipate being able to flash my first ROM.
It seems impossible, however, to read enough about the different ROMs to make an intelligent choice of which one to flash. Nor can I find a sticky on the subject. I am not looking for others to put any other ROMs down, I just want to hear if anyone can give a positive recommendation for a ROM that you think is best for what I need (in order of importance):
Extremely stable on AT&T i897 (I am running stock JH7 right now). For example, I remember reading for Phoenix that there's a complicated process required to get the 850 MHz radio to work. That is not cool for my needs. I need both of AT&T's 850 and 1900 bands to work stably and without additional hacking.
Very large user base and very active maintenance of the ROM so that I know that the major bugs have been worked out (probably the same as criterion 1 above)
Great battery life (need not be the absolute best)
Better GPS than stock (I understand that doesn't take much)
Faster performance than stock (does not have to be very/blazing fast, and this is less important to me than battery life)
Good wireless tethering (I hear the "Wireless Tether" app is less than ideal because it is not visible to most phones)
Preferably would like to be able to upgrade to a newer version of the same ROM (if I choose the right actively-maintained ROM in the first place, I won't be looking to switch ROMs in the future anyway) in place, without having to use ODIN or reinstall any applications or reconfigure any settings (like my Dolphin bookmarks) every time I upgrade. I'm not sure if this is never possible, or perhaps is always possible with Titanium Backup.
I could not care less about themes, wallpapers, boot animations or anything related to look and feel. I'm by far a function over form kind of guy. Unless of course the theme, such as a dark theme, contributes significantly to battery life savings.
Thank you so much in advance for any recommendations you can provide!

try the rom in my signature.... Version 1.0
you wont be disappointed
well, let me start of by saying, congratulations on posting in the correct area! you can catch quite a bit of $h.t for post in the wrong area! as far as the best ROM and well maintained, me, personally, I'm running Firefly 1.5 battery life is amazing. it comes with Mobile AP for tethering (which is extremely reliable) gps is awesome! HUGE user base, and the DEV's are understanding and will answer any questions you have! number 1 rule of flasing custom roms... BACK UP ALL INFO, I usually copy all files from internal SD and external SD to my desktop! as far as reinstalling your apps, TiBu is an awesome app, it saves a copy of the APK and the data you have with it, but it is time consuming to do a batch restore, but WELL worth it!

Yeah...I agree try Andromeda 1.0. If you are not a theme guy, then basically all the other ROMs are based on the exact same base with the exact same MODs. The only thing that really differs is a few tweaks here and there and the theme. Andromeda is build on the Armani Captivate build, and many people are finding it more stable. There is a 1.0 unthemed and a 2.0 themed. In addition, you can try out Cognition or Serendipity. Both are very stable
I'd look at DesignGears Cognition ROM. It's based off of SGH-i896 2.2 release in canada.
When I used it, I never had any problems with it, there are tons of additional features than stock, battery life is amazing, and it's just a much better ROM than the traditional i897 stock ROM.
Get the one in my sign.
LOL, see everyone has their own preference! TRY THEM ALL! become a flash addict like the rest of us!!
Your requirements look a lot like mine. I'm sure there are many great ROMs - depending on what someone is looking for. I'm using DG's Cognition and have been very pleased! I find it to be tremendously stable, though obviously much better (and faster) than stock. Battery life is awesome. I generally end the day with 40-50% left after what I'd consider to be moderate use.
Everyone will have their own opinion on the roms they use. Also remember that the same rom with the same set up will not always run the same. Each device is different so. Sense you require such tight guidelines I would stay stock, and read each thread till you find one that you think is stable enough for your uses. There is never a promise that after flashing a rom that an issue will not pop up that only effects you and your device (seen that happen lol) Also if there is a major update to the rom you chose you may have to do a back up and restore of the apps you installed and set things up again as sometimes you just have to revert to stock (yes I know some say they never have, but then I have never had an issue other then the ones I have caused my self). Your best bet is sense you have such tight restrictions on what the rom needs to ba able to do is learn to make one your self so you will know it meets your rules.
We dont do best rom threads.
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

99% of the time no one starts a flame war except the people flaming the person who started the 'flame war'. Honestly though it is preference (although some ROMs are better then others stability wise)

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.

OK guys, I need to know which roms are the best for the captivate and why. I am a Vibrant user and have been flashing for a while now, I have a buddy that has a captivate and wants to finally root and flash something spectacular,,,,
The problem is I don't know anything about the teams, and roms for captivate. Serious input please, no flaming or bashing, I really need the hard info,
Battery life, looks, ease of use, modems, kernels, etc...
Thanks
adamholden has some great ones like the: phoenix rom, firefly rom and the new supernova rom (running it awsome) also the serendipity rom

Took a look at the serendipity rom, looks like a good rom, how stable have the roms from this developer been? And they include the voodoo lagfix from supercurio correct?

Serendipity is stable. Mikey is very active with fixes. It uses hardcores kernel which uses ulk lag fix, which is similar to voodoo

Thanks for the quick response. ulk? have to research that one. But I do like what I have been reading in the serendipity thread.
Can you tell me anything about the pheonix rom? reading thru that one as well, and not seeing many bugs reported there either.
BTW leaving work now, won't be back on until tomorrow so if I don't respond again until tomorrow, Thanks for your input. I hit the thanks button on one of the other posts for you.
Phoenix uses same kernel, although an older version, and lag fix. Also stable also active dev. Matter of opinion as to which is better.
My two cents, currently my favorite 2 are paragon and stripped
IMO Andromeda v1.1 is an smooth stock like rom. 1.5 to 2 times the battery life from JH7 stock rom and better signal coverage.... it utilizes the 850mhz band better than the stock rom.
My vote is for Paragon...awesome and the kernel is super!
Phoenix is also a nice rom and the new Sucker Punch kernel seems to be doing great too.
I stopped using Serendipity a while ago as I did not like some of the changes that were introduced but I need to test the new versions.
I have tried pretty much everything else and those are my top too.
Currently testing Supernova.
Hi,
I was about to post a similar thread. I have an Evo & a buddy of mine who has a Captivate has been having some issues related to Android 2.1. Are these custom roms (Paragon, Phoenix, Serendipity) all Froyo 2.2 roms?
I am an Evo "Fresh Rom" user at first, now I stick with CM6.12 & try nightlies often as well.
Any advice for a solid 2.2 rom would be great!
Thanks,
Rich
I really recommend docs, I'll post link at the end, but I've had the best battery life and stability with it, also the rom kitchen is a huge selling point. You can generate a "cooked" rom with apps, modems, kernels, themes, boot animations, sounds, keyboards, tweaks, to your liking. With many of each to choose from. Very easy, with wipe and no wipe flashes available, pick and choose, don't like something then cook another, no biggie. Themes are most of the popular ones. I've cooked many myself, here is the link to the rom kitchen: http://romkitchen.org/capt/?s=home With out actually generating the rom you can select and choose to see your options. Hope this helps I will also post the roms link
Sent from cappy running docs gingerborg 9.1.8, hardcore k13A, jk4 modem.
I'm actually running gingerborgmod 9.1.8 its a cooked version from borg based off of docs, sorry I don't have link but you can search, he has been updating it with all the latest goodies, kernels etc. give either the kitchen a shot, or gingerborgmod. A shot don't think he'll be disappointed. Any questions just ask.

Tooka a look at Docs kitchen and pretty cool, would be better if I knew the specifics on all the stuff. Guess I need to do some research on the captivate modems, kernels, and other stuff
this is my setup.
Serendipity 5.8
Suckerpunch build #48 OC to 1.12ghz and undervolted
JL3 modem
and i find that i get better battery life with juice defender. some people hate it, but i seem to do better with it....
and with just basic usage, calling, texting websurfing, my phone has dropped 30% in 12.5 hours.

Can someone recommend a 2.2 Rom? i am a little confused if the above listed roms are 2.1 or 2.2?
i'm currently using a cooked up ROM from the Kitchen, and so far it's my favorite Captivate experience. if you know what to do with it, it's nice, and regardless very sleek and smooth. Andromeda, Serendipity, and Firefly are all worth a chance too, some of my favorite ROMs
Hi,
I have a few questions about Custom ROMs:
1. I have a basic idea about custom ROMs, but what why are there different Kernels for the same hardware? And is one better than the other? What makes a certain Kernel, better? As I understand with custom ROMs, you don't really have a choice in choosing the kernel you run, because each ROM is built on a specific kernel - am I correct about this?
2. I am looking to put a gingerbread 2.3 ROM on my Samsung Captivate, and I am looking for a ROM which is minimalistic Android and doesn't come with, shall we say 'bloatware' - for the lack of a better word. Of course, I would be looking for something stable and optimized for performance. Any recommendations?
Thanks.
1) Different kernals do offer different features. But they are swapable. That is why the kernals are available in seperate threads in the dev section. The biggest feature that is kernal dependent is overclocking. I have never been a fan of overclocking, don't think its needed on this phone. I also have never had good luck flashing different kernals. Whenever I have tried that the ROM runs buggy, freezes, lots of FCs. While you can change the kernal at any time, I have always found best performance with the kenal the dev chose to include with their ROM. I'm sure there are a hundred people here that would disagree with that. Just like ROM choice it's a personal decision.
2)ALL the ROMs here 2.2 or 2.3 will be de-bloated. I have tried all the 2.3 ROMs, and the only thing that is consistent with them is their unstableness. I can't get more than 2 hours of use without a freeze that needs a reboot, or it rebooting on it's own. The only reason I a sticking with a 2.3 ROM is Netflix. The app works on the 2.3 ROMs, but I cannot get it to work on 2.2. If you want something stable and optimized for performance: stay on FroYo. I recommend FireFly. If you want to take the plunge to 2.3 (after you have read EVERY GB sticky twice, paying attention to the bootloader info, or you'll have an expensive paperweight) I recommend GR, Perception II, or Mosaic. Mosaic was the most stable for me, but runs the same touchwiz as froyo, so it just feels like buggy froyo. The other two run touchwiz 4 from the SGS II.

I have to respectfully disagree with quarlow. He is right about the the kernel swapping, and whatever kernel that comes with the ROM is gonna work and work well. The thing that distinguishes different kernels from one another is again the ability to OC and there is also BLN features and UV capabilities, so it is all user preference. HOWEVER it is the same as flashing a ROM. I have NEVER had an issue or seen a ROM get freezes or FC's because of flashing a different kernel. Not unless your are OC'ing. But it could just be my luck too (with the exception of the trident kernel which came OC'd to 1.4ghz, which was silly because if your phone can't handle that, it won't boot.. luckily mine can)
As far as the 2.3 ROMs go, again I have to disagree. I have been running CM7 for weeks without a single issue. As a matter of fact it keeps getting better. I'm not gonna talk up CM7 but I will say if that other user cannot get more than 2 hours without a freeze or having to reboot, then he is doing something wrong. I have tried Perception (beta2), and C5 RC3.. both are nice. Especially if you want a samsung ROM with all the features you are used to. CM7 is completely different built from AOSP. IMO, they are all really stable to use on a daily basis. Again, if my phone was freezing or needing a reboot every couple hours i would NOT be telling you they are stable.
All the 2.2 ROMs are sweet.. all user preference. Like the quarlow said, make sure you read the OP and re-read the instructions. Bootloaders are something you don't want to F up But, CM7 just got easier, and you don't have to flash any i9000 bootloaders.
Just my 2cents

I take no offense, that's why I said there are probably a hundred people that will disagree with me ... the kernel game is not a game I enjoy. I have never had trouble until I had a ROM with OC enabled, and got the sleeping death, flashed a different kernel, and got freezes, general buggyness, and FCs. I ended up downgrading to the older non-oc version to avoid the sleep death, and had no problems. I have only flashed a kernel a few times before that, and because of that experience none since. Maybe my experience was a fluke ...
I have never tried CM7 because the last time I looked at the installation instructions I didn't feel I understood them well enough ... because of how different it was to the FroYo ROMs of the time (Recovery then install ... 2 steps). Looking at it now, it's not nearly as unusual after all the i9000 GB ROMs. I really have had bad stability with the i9000 GB ROMs. Not that it freezes every two hours, but after two hours of constant use it freezes, and needs a reboot, or every once in a while while listening to music the music stops and I look at my phone to see it have rebooted for no reason. All of the i9000 GB ROMs I have tried did this (some worse than others): Perception, Continuum, GR, Mosaic, Symply, subpression, etc. I've gone back to Stock eclair with a Master Clear, wiped the various caches, nothing I do seems to fix this. I have attributed it to the Beta tag that is still attached to most of the ROMs. Maybe this weekend I'll give CM7 a try.

Yeah, i guess now that i look back on C5, there was some lagginess to it- but having the samsung cameras back were a bonus CM7's install is now done from froyo ROMs.. Much easier than the Odin stuff before. Don't even need a computer now
Quarlow ... I think you got a lemon..
If everything was as buggy as you make it out to be I don't think the captivate would have as much dev support as it does. Or as many flashers, If all of us are running fine on our phones and you are the only one with these huge issues that I've never even heard of (force closing from swapping out a kernel) maybe your phone has got a less than adequate component in there, inconsistent builds are a very real thing and looks like yours sucks...

How do I fix that? Go to att with "Bad GPS"? My GPS has been fine. I have a build 1006, had this on hold for me the day they released. Never had shutdown issue except that OC kernel I tried. My warranty is going to be up in a month, think I should try to swap before that runs out?
Sent from my Captivate running GR-12
I'd say so ... I have never had the issues you have. I have run every rom with every kernel, never once caused a force close and all the gb roms I've been on have been pretty stable 2 days without even charging let alone reboot.
Does your phone actually have ****ty gps cause if you use that excuse you're gonna have to prove it ... if however your phone for some "strange reason" doesn't boot at all you could use the "i was using kies and it never came on" excuse....
But if you have bad gps while on stock that should be enough to swap it out.
My GPS has always been fine. Longer time to get a lock than my iPhone before, but with 15 seconds it always gets a lock. Would I be better to go with random shutdown?

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.

It depends on what city u live in...if u live in an urban area, then I would recommend the jl3 modem
As for roms...cm7 gets decent battery..
U might wanna check out a rom called juiced which was made for battery life...I get 4 days of light usage on that rom!

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.

Ok, i think i got it all here.. Now grab yourself a snack and start reading!
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

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.
