Custom Rom Options?

Hey everyone. I'm posting here because I have a friend with a Captivate and I'm trying to get him to root his phone.
I sent him the link to the 1 click root but I don't know what rom to have him flash. I have an EVO and in the EVO forums we have a sticky with all the custom roms listed so it's easy to see what's there. Is there anything like that for you guys?
He's basically looking for a stable 2.2 rom.

The Captivate DEV scene isn't too large right now, (most of them are in the Vibrant section) We have few custom roms, but the ones you can find, along with mods can be found in the Development section of Captivate.

This is very true. Most went to vibrant because they were ex-G1 users. However the good news is the most of the coding will be the same so they are relatively easy to port. I have a feeling the captivate will not be getting as much dev action, and most people are switching from windows mobile or iPhone and have no android dev experience. But it will eventually speed up

Don't have him flash a custom ROM just to flash a custom ROM. Right now there are a limited number of ROMs, and he can read up on them in the dev to see if there is anything changes in the newer firmwares that would make it worth his time to flash. AFAIK, there are no fully functional, stable 2.2 ROMs (although the leaked build for the i9000/international version does mostly work, I think). There are also a few leaked updates to the 2.1 firmware.

Yea, that's why I am asking if there are any stable 2.2 roms yet. But as I gather there aren't. I'll just tell him to keep his eyes open here.

I've been using Cognition 2.2b6 for about 4 months now with no problems. Seems to be the most stable rom out there for the captivate.

I've been using Cognition 2.3b3 for several weeks and it's working great, the only issue for me is the android email process crashes on startup, I use the gmail app anyway, so its a non issue for me... It took 3 or 4 days to get the correct order of opperations, it seems not everything you find on XDA works for every Captivate, I guess AT&T keeps disabling settings and crapware crippling the phone... But the order that worked for me was:
STOCK AT&T 2.2 FROYO:

Now that I've done all this I could NEVER go back to stock, it's like having a completely different phone... Unbelievable upgrade. F-U AT&T.

Hands down Cognition to start. When he's ready to move on Cognadian Bacon!

I was gonna say perseption. Its really the most captivate friendly of the ports for other galaxy s phones. You get the reorient kernel with overclock undervoult, universal lagfix, clockwork mod instead of 2e recovery, and you get working bluetooth audio, normal batery life, multiple fonts, password/pin number/pattern security, other things i forgot.
Axura looks amazing but noone will answer my questios about bugs. And there is no known issues listing.

Hey saw this Vid, wondering what rom and kernel he is running, if anyone knows which they are please let me know. thanks
http://www.youtube.com/watch?v=jjH5PRfsh0Q&feature=iv&annotation_id=annotation_609190

first off this a tech demo and not a stable day to day use rom. You will not be able to use this normally on the phone (reagular reboots and instability) it was simply a taste of gingerbread for some devs here. I would highly recommend not flashing especially since you aren't really experienced yet. You should flash one of the many stable roms in the dev section, but if you insist on it, here is the thread for it:
http://forum.xda-developers.com/showthread.php?t=887037

i tried dling this rom and installing from clockwork recovery as a zip and it says it installed and takes me right back to the original rom i started with. also is there a kernel i should flash to make things more stable. thanks

I'm pretty sure you have to flash the 2.3 kernel for it to boot into gb. But as joeshmoe said, it isn't a good idea if you aren't experienced (I bricked a capivate trying to get this to work, seriously, it isn't a good idea). There's plenty of great froyo roms out and some nice gb themes, I'd recommend just taking that route.

It *is* being developed for the Captivate, but not on a native Captivate kernel. The reorient, headphone, button fixes are native to the i9000 port when it detects the hardware as a Captivate.

Don't flash it. Seriously. Codeworkx/Coolya were digging through the source, and the nexus s kernel source has differing voltages than the galaxy s. ie, it can actually destroy parts of your hardware. Wait a couple of weeks, the rc for CM7 should be out by then.

well i dont plan to use the rom long term just wanted to flash to it and mess with it then probably switch back to a froyo rom shortly after. but having an issue getting it to run. if i download a kernel with voodoo and run the lagfix to ext4 then flash the rom should that get it up and running?
edit: went ahead and flashed perception and then the rom, reboots constantly, so looks like ill go back to perception and tough it out with a gingerbread theme. Gonna miss that lock animation.... ok now anyknow know how i get back to recovery mode, or do i have to flash back to stock? and reroot?
edit2: dont flash this rom, waste of time, just play with your friends nexus S, back to serendipity

All for a lock screen animation......... wow.

[Q] What is the best rom for captivate..

Hi all Thanks to all.... Newbie here with flashing and all so i just want to get started on the right track... being doing alot of reading just wanted to know what is the safest rom right now for the captivate....
also ive downloaded bay_wolfs AIO captivate tool ...if i use this tool i dont have to go through the the whole process of installing rom manager..zip files etc..do i if i read correctly..well thanks all in advance for the responses.....

It depends on What you want. For a really bare bones rom, use precision. For a close to stock rom, use cognition. For a well themed and polished rom, use serendipity or ultimate. Cognition is the only captivate based one though.
Sent from my GT-I9000 using Tapatalk

yeesh - sorry but most of these get locked in 10 posts or less as these become "My ROM is better than Your ROM" epeen arguments.
With that being said.. if a ROM is posted in the Dev forum and as long as it doesn't say Cyanogen Beta or Gingerbread alpha AOSP in it? It is pretty much safe to flash.
Most of these ROM's use either a Rogers, Captivate, or i9000 Source and don't deviate other than tweaks to apps/kernels/modems/lagfixes/themes.
If you want to be safe - I would go with Cognition as a first ROM flash then go from there. It is basically "stock".

Thanks guys for the quick posts....Just a little worried about doing it for the first time i have read, watched videos, this is why im asking before taking the plunge...
i really like Bay_wolfs tool seems great for newbies has anyone used it...i think i may go with cognition is there a better version than the 3.4 what i mean is the newest version seem best or and older one...

I also flashed my first ROM the other week after lots of reading and studying. I went with Andromeda 1.0 at and have since gone to 1.1. I didn't use the tool that you're wondering about, but have downloaded it for future use. So if you do use it, let me know how it goes for you. I went with the installation instrustions on Andromeda's website, and that worked flawlessly. Once you do decide on a ROM, I'm sure that you'll be extremely happy as the performance is way better than stock. Happy flashing and good luck!

Like the other posters said, it's all about what you want and then personal preference. Once you have flashed a few you will start realizing what you do and don't like about the ROMs and what you really want in them. (My first ROM I had no idea, I was like, lets just flash because it's cool and custom and I feel like it. Then I started noticing the differences between my first ROM and stock, realizing what they can actually do with it and what they cannot. From there I figured out what I was really looking for by going custom, and starting browsing the released ROMs to find it)
In short, your first ROM is just that, the first. It wont stay there long so it doesn't really matter which one you choose. Cognition, like stated above, is a good start because it's pretty close to stock. If you want to just straight into a very custom one and screw the baby steps, try something a little more feature rich. Eventually you will get into trying different ROMs with different kernels and test out over-clocking, etc...
I would recommend for your first that you don't go with an OC ROM though, save that for when you feel more comfortable with your ability to flash and tweak things.
I have never used the tool you are talking about because I feel more comfortable doing all the .zip stuff and seeing what is actually being done to my phone, not trusting something else to do it. The tools I do use are Odin3 and One Click Root/Unroot. If you want to try flashing without that tool but aren't sure of the exact steps or why they are necessary you can PM me and I'll help you out.
Welcome to the addiction of ROM flashing! (It's harder to shake then cigarettes once you start)

You guys are great here thanks for all the tips...tonight i will be flashing my first Rom hope all goes well if i have any questions i will ask...once again thanks...

Do not flash any of the Gingerbread ROMs unless you really know what you are doing. They are still unstable and you risk bricking your phone. As for stable ROMs, there's a wide variety of them, and they're all based on Android 2.2, which is really fast. There is no best ROM, and it all depends on your personal preferences. Try visiting a few of the ROM threads to check them out, and hopefully that will help you decide which one to flash.

A bit of an overstatement, but I concur on there is no best, find what works best for you
CM7

Ok well not 10 or less this time but close.
There is no best rom just best for you. I could say Rom X is the best and does everything I need it to and when you run it, you dont like it or doesnt work well with your set up.
Thread Closed

[Q] Lots of questions before I flash my device.

So, I have a SGS I9000t and am currently very frustrated with the official firmware 2.2.1, since some apps are having terrible issues. Whats worse is that lots of my programs are having constant crashes. My available ram is always getting capped, and i have to uninstall some programs that add functionality that while unnecessary they're nice to have.
Now I have been thinking, what to do? I hear I could flash my device. Doing so would improve its performance, even update to gingerbread. So now i have some questions. I bought this phone and recklessly installed darky's rom. It worked, but without 3g. Other than that, it was pretty amazing. I kept screwing around with it trying to fix 3g and finally bricked it. Took it in for warranty and got a new one.
I dont want to repeat the same mistakes, so this time i want to be extra careful.
Is there a way to do a complete backup? Like every single piece of data in ALL of my phone's memory backup. In case this flash goes wrong, I can just make it work just as it was before?
Is there a way to try roms before flashing? Like just load a rom on top of another rom without altering the current rom.
I would like to evade roms with 2.2.1 firmware, because of the problems mentioned before, so whats the best, non 2.2.1 rom available? Most stable, just plain best.
Since y phone is a i9000t my modem seems to have some problems when flashing, so here are the details of my phone: Model GT-I9000T // FW Ver 2.2.1 // Kernel 2.6.32.9 [email protected] #1 // Build FROYO.UBJP9
Im sorry if this is a lot of info, i just want to do this right. If I flash my phone its for better funcionality, not to get worse. Thanks for your time, if youve read this far. Hopefully you can help me out.

You are asking to be spoon fed information that is out there already!
1st rule of forum is look before you ask, people will help you if you make the effort, but you have to make the effort first. Sorry if this is harsh, so as a pointer, read the main q&a first as a starter

One quick question though, Im sure its not in the FAQ.
I have been dealing with my phone and I see now that many of the problems im having are created by the apps themselves. Will changing my rom actually help greatly? Is 2.3.3 recomemded?
Sent from my GT-I9000T using XDA App

samsung use rfs file system that decays over time, hence people tend to lagfix to cure this, ie. Convert to ext4, this is done through a kernel tweak, you need to start reading and learning, im sorry but I wont do your homework for you!
Sent from gt i9000 insanity 8.5/fugumod

Your problems are not due to 2.2.1 Its the best non GB rom .
Your first step is factory reset .
Second check Kies for an update .
Third step would be to remove these problem apps .
But i just spotted the problem at some stage you installed a darkys rom
Known killer of phones ..
Total removal is flash stock froyo 2.2 rom with pit and repartition checked .
jje

I flashed darkys rom but traded that phone for a new one. So I have a fresh factory 2.2.1 and its working very well. My biggest problem is the bug with programs resetting/not saving settings because the old data stays after uninstalling. Also the rom runs great, what im looking for is better compatibility on perhaps another rom. But you say its as good as it gets so I may be staying with this rom.
Edit; Also, I must add that Kies cannot update my device, because my service provider has my device locked on that firmware. Now what you suggest is flashing to 2.2, then updating to a stock gingerbread rom through Kies? Should'nt I just flash GB and get it over with?

If you go around looking for a problem, you are most likely to find one. This applies to more than just phone firmwares. Like you said, no system is truly perfect... With that said, I would recommend you try a custom ROM over any stock one... And Juwe's ROM is a pretty trusted one on this board... so sure, go ahead and try it!

I'd say that the voodoo plus app still will be quite useful as it works its magic regardless of kernel. You might find yourself on a standard kernel one day, and then you will still be able to enjoy the improvements of voodoo.

This is a known problem, i had it happen to me several times on froyo firmwares. Solution is to go into settings, applications, then clear data and cache of the problem program, then uninstall it, and go into /data and /dbdata/ and find any data the program has left behind and delete it. Reinstall the app from the market, and the problem should be gone. Havent had it crop up in gingerbread yet.

I've not been on 2.1 since phone came out. I would use odin one click to goto 2.2 stock. Root it then install cwm and then follow this guide if your going to try Galnet's MIUI.

Wow... so... You should probably READ a lot more before flashing anything, but I'll give you a few hints to get you going:
1) Make sure you understand what a "PBL", "SBL", "Kernel", and "Modem" are and how they are placed/installed in your phone.
2) Learn how to correctly and safely use ODIN (and/or Heimdall).
3) Learn about the various methods of recovery for "soft bricks", and if necessary for your hardware revision, possibly invest in a jig (also learn what a jig is)
4) There are 2 different types/branches of ROMs for the Captivate:
-- Samsung Branch
-- AOSP Branch
Within the "Samsung" types you have:
- i9000 ROMs (like JVP, JVR, JP8, etc)
- i897 ROMs (like JF6, KF1, etc)
Within the "AOSP" types you have:
- CM7
- MIUI
- Other AOSP-based ROMs
Which is "better" is relative. CM7 and MIUI have features that aren't present in the Samsung ROMs, and both offer a bit more customization than the Samsung ROMs. However, only the Samsung ROMs offer GPU accelerated video playback, and they tend to have significantly better battery life than the AOSP-type ROMs. Also the Samsung-type ROMs used to be much more stable than the AOSP branches, but recently, the tide may have turned in the other direction. Some of the low-level radio settings are also unavailable in any of the AOSP builds. And finally, some of the Samsung stock camera features are unavailable in CM7/MIUI.
It really all depends what you want... Do you want closer to stock "open source" Android? Or do you want Samsung's vision of what they think Android should be?
Also, the whole kernel/modem part is dependent on what branch of ROM you plan on running. When using a i9000-Samsung ROM, you pretty much have to use an i9000 kernel and modem. When using a i897-Samsung ROM, you pretty much have to use an i897 kernel and modem. The rules for CM7/MIUI are a bit more vague, but at the very least you'll need to use a CM7/MIUI (most AOSP-type kernels are interchangeable) compatible kernel.
The best advice is really to try them all out and see what you like the most. If you're currently on stock 2.1 (which it sounds like you are), at the very least you should upgrade to some variant of Gingerbread (2.3.4 preferably). You will definitely notice a big difference in terms of speed and functionality. From there, well, it's all really up to you...
OR alternatively, just start throwing stuff on your phone and see what happens. Just PLEASE don't come crying back in the Captivate General forum with a "OMG I bricked my phone!!! Plz help!!!" thread. Fair warning...

Just a suggestion, but become familiar with Odin one click. Make sure your captivate has 3 button recovery, and read, re- read, and read again the directions of every rom before you flash it. Always make a nandroid back up if possible, and read the threads.if you have questions, so did someone else and the answer is probably already out there .use search. Some People will rip your head off if you don't. as far as miui goes .....i was a flashaholic when I got phone. After switching to miui, It is very unlikely that I will ever leave. Best rom ever imho. And it updates every Friday so that satisfied the flashing urge. Usually it gets better with each release. The last couple have been a little rough though. Might want to spend the 8 bucks and have a download jig on standby. Can get it from mobiltech videos. Its worth it though

Wow... so... You should probably READ a lot more before flashing anything, but I'll give you a few hints to get you going:
1) Make sure you understand what a "PBL", "SBL", "Kernel", and "Modem" are and how the are placed/installed in your phone.
2) Learn how to correctly and safely use ODIN (and/or Heimdall).
3) Learn about the various methods of recovery for "soft bricks", and if necessary for your hardware revision, possibly invest in a jig (also learn what a jig is)
4) There are 2 different types/branches of ROMs for the Captivate:
-- Samsung Branch
-- AOSP Branch
Within the "Samsung" types you have:
- i9000 ROMs (like JVP, JVR, JP8, etc)
- i897 ROMs (like JF6, KF1, etc)
Within the "AOSP" types you have:
- CM7
- MIUI
- Other AOSP-based ROMs
Which is "better" is relative. CM7 and MIUI have features that aren't present in the Samsung ROMs, and both offer a bit more customization than the Samsung ROMs. However, only the Samsung ROMs offer GPU accelerated video playback, and they tend to have significantly better battery life than the AOSP-type ROMs. Also the Samsung-type ROMs used to be much more stable than the AOSP branches, but recently, the tide may have turned in the other direction. Some of the low-level radio settings are also unavailable in any of the AOSP builds. And finally, some of the Samsung stock camera features are unavailable in CM7/MIUI.
It really all depends what you want... Do you want closer to stock "open source" Android? Or do you want Samsung's vision of what they think Android should be?
Also, the whole kernel/modem part is dependent on what branch of ROM you plan on running. When using a i9000-Samsung ROM, you pretty much have to use an i9000 kernel and modem. When using a i897-Samsung ROM, you pretty much have to use an i897 kernel and modem. The rules for CM7/MIUI are a bit more vague, but at the very least you'll need to use a CM7/MIUI (most AOSP-type kernels are interchangeable) compatible kernel.

a very simple and easy way to start with...
2.1 is eclair..
2.2 froyo
2.3 gingerbread..
means 2.1 is oldest and 2.3 is latest in case of official roms..
so obviously new version will hav more features and faster in speed...
so now u can take baby step and install 2.2 ..and use it for few days..and get the feel of it..then again after sometime u can install 2.3...
or else u can directly jump to 2.3....which is gingerbread....u can install stock kf1 on ur phone..its leaked official gb...if u search a bit..u will get it..
then u can use it for a lil while and get the feel of gb stock rom..in the meanwhile u can read xda abt available custom roms..and then install any of them...
coz every memeber here in xda will suggest the custom rom they r using..coz they r lovin the rom then only they r using....like for me..since the time i started flashin..i always used APEX ROM..so i will say its the best....
but again thats just me..
so decision is always urs...
