Are there any differences between different custom firmware???
I tried Tayutama and DocMod.
Other than the pre installed apps, I could not find any major difference.
If the differences are more underlying, can someone tell me what they are?

Ive been trying to do alot of reading in learning the past week. i flashed my phone maybe 9 times already atleast. Now i keep reading abouts modem versions then kernels then roms. what are the difference? are they each upgradable on their own? Or do the roms upgrade them by themselves. Thanks in advance.
Some Roms upgrade through rom manager. But most of the time you have to flash the new version to get the update. Don't know much about kernals sorry but may somebody cam clearify for both of us
Sent from my phone exuse the typos(if any)
Put simply, the kernel is the part of the software that talks directly to the hardware, different modifications are included in kernels, such as lagfixes, the ability to overclock, and BLN (backlight notifications). Most of the custom Captivate kernels you see are in fact i9000 kernels that have been tweaked to work on our phones.
Once again put simply, a ROM is the operating system of your phone, it includes applications such as the Launcher, Phone, Contacts, Email, Calculator, Calendar, Market, etc. as well as any custom settings put in by the ROM maker (AKA chef) such as the sideloading of apps and root access. ROMs can be added onto later by the user such as the installation of themes or the removal of bloatware. Most of the recent ROMs are based on i9000 ROMs.
Modems are the software that talk to the cellular radio in your phone, they also seem to effect GPS performance. Modems are bit different from kernels and roms in that there aren't any custom modems. All the modems you see on the forums are from Samsung. Modems from several different Galaxy S variants work on the Captivate.
Most ROMs (and ROM updates) are prepackaged with a kernel and a modem, but all the parts can potentially be upgraded separately with the right knowledge. One thing to keep in mind is that to avoid issues you should not mix your parts. For example, in most cases if you use an i9000 modem with a captivate kernel you will not get any sound on phone calls.
The best thing to do before you flash anything is to read, read, read.
I've tried searching various forums but have only encountered lots of noise, so I thought I'd ask this seemingly simple question:
What's the difference among the different base ROMs that have been leaked, e.g. JS5 (the most recent version) vs. JS3 vs. JPY vs. JPX vs. etc.? The more obvious answer is kernel and modem changes, and the next level answer is various bug fixes or optimizations, but are there changes that can be more specifically identified besides those and what, if any, advantages one ROM offers over another?
Many thanks in advance!

Base roms are either from different devices our an updated version with bug fixes. Jpy, js3, js5 are all almost identical with slight changes.
Roms may have the same base but different kernel and modem. So just because two roms are js3 does not mean they are using the same kernel modem combo
Noob question here, or major brain fart...
I just installed a kitchen rom. and all things work pretty good. I want to install a theme on my SGS.
But i'm a bit confused as to what all the versions that themes are compatible on mean.
The base rom version i got was the ZSJPJ one. (I also have ZSJPK but i screwed up some apps so i went back to JPJ) i can always cook up another JPK one.
When i browse themes, i can't seem to find one that says it's made for JPJ. They all are made for different versions, and i'm coming to think i'm just missing something... For example a theme will say made for JPU/X/Y. Will that work with mine? Should i be trying the JVx ones? or the JSx ones?
Any insight would be appreciated...
JPx and JSx work fine.
JVx are fror Gingerbread (not the same framework).
okok, thanks. I was making sure... cause i dled one of the JPx ones and it caused some FC's when i booted up. Maybe it was just that theme.
Make a Wipe Dalvik cache after installing your new theme.
Flashed loads of stock and custom roms and currently running stock JVH chainfire rooted.
I'm toying with the idea of flashing a deodexed rom and if I do will probably start off on a stock rom from Ramad - certainly before moving onto a deodexed custom rom.
Question is: is it worth it? I've read the technical differences between odexed and deodexed, but what are the ACTUAL benefits.
Please no replies from people who haven't done it just quoting the same technical information we can all read.
Very interested from those who have - why? why not? what are the performance differences? pros and cons?
I found a thread from April but interested now to hear from all the gingerbread users
thanks
The biggest advantage is you can install themes and various other mods (i.e: different lock screens, extended menus, enable hidden options, and many more..).
It's still possible to install themes on odexed, but not all themes are compatible (Read carefully ).
As for performance.. odexed is supposably slightly better from what I've heard, but I can't tell any difference myself (running odexed JPH atm).

True, but the they are very rare and limited in their theming ability.

You sure? If odexed is "better" why go to the trouble of flashing deodexed ?

Hi Mossy,
I've been toying with a few deodexed roms of late and honestly, there's not really any noticable difference in feel or performance.
The main benefit has already been mentioned, and that's more compatibilty with custom themes and such.
Some say deodexed has better memory management after the caches are built. Would you or I as a user notice this? Probably not.
OK....thanks guys, appreciate your comments
i opened all the files one by one comparing them.. apart from the csc differences, there are 2 more differences between those 2 roms.. one is the keyboard and sywpe apk s are different.. they are switchable so no big deal.. but there is also one more differences in the directories of "framework" and "lib" .. i can understand they are referring to some differences between 2 roms but i cant find these differences? can you tell me what they are exactly and which one to choose?
*i am also curious about the differences between kernels too.. but i know its not big deal because i always flash new kernel.. but it would be nice to know which is better of course
**and which kernel has been given by samsung as updated new source code?
