[Q] Backing up Stock ROM noob question

I'm really a noob in hacking my captivate. So please bear with me with all my questions.
I've tried my best to educate myself about different mods, especially clockworkmod and nandroid. But I couldn't understand what each of these does. I did "Backup Current ROM" in ROM manager recently. (1) Is that considered to be a ROM backup that I can use in the future if I want to restore to stock ROM?
If so, (2) what is the different between that backup method and Nandroid method? I didn't do Nandroid backup because I don't understand how to install it.
(3) If not, am I screwed? Cause I already performed several mods: Voodoo lagfix and ATT app removal. But my captivate is running fine.
I just wanna make sure I can restore back to my Stock ROM when 2.2 update is available. (4) Do I need to restore stock ROM in order to receive and install 2.2 update?
Please educate me on this matter. Thanks!

I use nandroid once I installed a firmware or ROM and apps (Titanium Backup User apps + System data and restored on the ROM Missing Apps + Data) to make a backup.
Now I can restore Nandroid and all my settings/apps are there.
Use Titanium backup to get your apps/settings onto a newly flashed firmware or ROM.

2 good options... My favorite is to use rom manager to do a rom backup.

1) clockwork mod and nandroid (ROM Manager) are the same thing.
2) as clockwork stands RIGHT NOW (should be changing soon), backing up your current ROM does NOT change your kernel or modem. clockwork is also incompatible with voodoo (you have to disable voodoo to use clockwork, and you can restore voodoo once you're done)
3) to restore to stock "out of the box" state, you will need to use the odin one-click downloader for the Captivate.
4) the process for updating to 2.2 is unknown at this time, we won't know more until the option starts rolling out.

Thing is, this isn't EXACTLY "out of the box" state. This is a new install of the stock ROM, but it's missing some things that are on the original phone like the file with the easy to get unlock codes.
What I would like to do is backup the entire device as is when it comes out of the box. Basically create an image of the existing device. That way, if I have to revert at any point I know I'm not just reinstalling the stock ROM, but actually reverting to this phones original state.

Hmmm, good question. The only way to back up that I know of is to use ROM Manager. Since that requires rooting the "damage" may already be done.

The date of the kernel is different from the stock one as well, someone else tried to flash the original stock kernel but said while Odin showed the kernel took, the phone still shows the same with the different date. It would be nice if there was a way to get a completely original stock ROM, so if you have to exchange or something at ATT. I don't know how in depth they get at the store so maybe we'd be able to get away with just the Odin One-Click and they will accept it. If they check the kernel date though, you're screwed. Either way though, once the update comes out, rest assured that someone will post it on here for those of us not running completely original out of the box stock, which I always appreciate.

[Q] New to the Android Hacking Scene | First Steps

So as of Oct 1st I've been the proud owner of a Captivate. This is upgrading from an Ericsson feature phone, which while I hacked, the scene here is very different. Moreover, the organization and level of detail I tend to find things is a little lacking (yes, I've used the search feature). I understand that the Android platform is spreading rapidly, the Captivate especially, so I will say I don't fault XDA or anything. I'm just trying to educate myself (and hopefully be able to help the community later) via a massive post on breaking myself into the Captivate hacking circle.
Most of the below are questions that fall under some kind of similar topic.
What do the I8000/I9000 terms pertain to? Which phones or firmware versions are which Ix000? How can I check for myself in the future? (I'm under the impression that the Captivate falls under I9000, but still I'd like more firm determination.)
How many ROMs can be active on a phone at once? (Can a ROM be just some UI changes, on top of another that changes some backend file organization or, say, another UI alteration for a different section of the phone?)
ROM Manager + Clockwork Mod seems to be the defacto tool for flashing phone ROMs and creating backups with the Captivate. But I've also seen people suggest using Titanium Backup often for creating backups if the user wants to have a stock state of their phone to revert to in order to go back to a clean slate. (Only real difference that is apparent is TB seems to use the word "image" and not "backup", but if that's the case then what does a "backup" count as out of ROM Manger?) And what of Odin? Or Nandroid? I get there are different methodologies to do the same thing, but it’d be nice to lay out the details, uses, pros, cons, and comparisons between all these backup utilities.
Thanks in advance!
EDIT: Shoot, thought I was on the Q&A page. Feel free to move. Apologies.

While you are in development look at the captivate bible, it links to the important threads, I think there is a wiki up somewhere too that answers the important questions.
Titanium backup backs up apps and data but I don't know if its in the form of an image, certainly not a full disk image.
Nandroid is a feature of rom manager/clockwork recovery, I believe that is an image but I haven't actually used a backup from it yet so I don't know if it is or isn't.
Odin is a tool for flashing samsung firmwares, 3rd party roms can use odin and a hybrid can be made my mixing one rom with another kernel or modem.bin.
Most recent 3rd party roms use a .zip file run in clockwork recovery which can be launcher from rom manager.
Some mods and I think a few roms are run as an update.zip in the stock recovery screen which you get to via a button combo on boot up. Hold both volumes for 2 sec then press power and continue holding all 3 buttons till the att screen pops up.
Since you are new to android, I'd look at designgears work, or eugene. High quality stuff. Cognition 2.2 is based on leaked froyo and is probably the best gps and fastest, linpack shows the best numbers with froyo(2.2). But for 3d gaming the overclock (only on eclair (2.1)) will give better frame rates from a higher gpu clock. Not that the humming bird needs better 3d performance. It already leads the field in that area, most benchmark are ineffective because the gpu is capped at 56fps and it will hit that cap through most tests.
Kernels for overclock/undervolt and/or voodoo are loaded into condition 2.1.x and can be added to other eclair roms with ease.
eugenes roms are very thought out but take a while to get right on the captivate since he has a vibrant and there are differences.
I-9000 is the international galaxy s and is the most feature rich version that is gsm, many files roms ect can run on the captivate with some bugs, I-9000 kernels are used to enable hsupa, but break the bluetooth.
Lag fix is a ext2 or ext4 partition to boost file system speeds, ask a dev about how that works, I have no idea. Voodoo lag fix, I think is a full file system replacement and considered superior. its not available in froyo, we have no source code for froyo to build the kernel.

It is the Samsung's code for their devices. For example :
i900 --> Samsung Omnia
i8000 --> Samsung Omnia II
i9000 --> Samsung Galaxy S (International)
B7610 --> Samsung OmniaPRO (the touchscreen slider)
C6625 --> Samsung Valencia
And finally, i897 --> AT&T Samsung Captivate

No, only one ROM can be used in the device at the same time. It is recommended to flash stock ROM first before flashing non-stock ROM, to avoid conflict between ROMs. Every non-stock ROMs is made to replace stock ROM, not another non-stock ROMs.

ROM Manager & Clockwork Mod --> Same utility, get from the market. Flash stock ROM first. You don't need PC to flash with ROM Manager/Clockwork Mod
Odin --> Conventional way that needs PC to flash the ROM. Flash stock ROM first. Usually ROMs that need Odin will be available as .exe file, and the .exe file contains Odin with the ROM, so, you don't need to download Odin separately
Titanium Backup --> A backup app, get from the market. It will generate an .APK file that contains the app with their data (for example : saved games) as an .APK file. After flash the new ROM, just reinstall the generated .APK file. It can backup app (with data), WiFi settings, contacts & calendar (better use your Google account), SMS/MMS (better use separate SMS/MMS backup app from the market), Call History, etc
Nandroid --> I don't know, never used before.

Nandroid is a function of RM/CWM wherein it take a full snapshot of the current rom setup: system, application data, etc. (no, it does not copy the entire internal SD card.)

Well, your questions are pretty standard things, not really related much to actual dev work.
I will point you to the 3 most important things you will need to get started.
apk manager
auto-deodexer
apktool
...and the obvious dev tools, netbeans, android sdk, etc...

[Q] Not sure about installing themes/ROMs

Recently I installed the ROM Cognition, and want to theme this ROM.
As I understand, I download the theme, rename to 'update.zip', and install via recovery mode just like I did the ROM.
Here is where my question comes into play:
1. Some themes say they only are compatible with certain numbers/letters, such as: J16, JFW or things like this. How do I know if my phone will work with specific themes? I want to make sure that I do not brick my phone.
2. If I want to install a new ROM on my phone, should I flash with Odin back to Eclair 2.1, re-root, and install the new ROM? Or can I do this from ROM Manager with a backup of my Apps on Titanium Backup (and how do you export this to work on new ROMS)?
Thanks in advance

you should not be renaming ANYTHING to update.zip. you should be flashing roms and themes through clockwork mod recovery....

Yeah you're right. Can I go from one ROM to another without flashing back with Odin though?

In most cases you can flash one rom over another successfully.

1. Some themes say they only are compatible with certain numbers/letters, such as: J16, JFW or things like this. How do I know if my phone will work with specific themes? I want to make sure that I do not brick my phone.
Need to check what type of modem/kernel you have currently on your phone for compatibility. Go to Settings -> About Phone and look for the last three letters under Baseband Version - that will tell you if <x> Theme will work for your phone.
Also - it is highly suggested that you backup your framework-res.apk and twframework-res.apk before attempting to run the theme. This will prevent you from having to re-flash your entire phone. (Will need to use root explorer and be familiar with ADB commands to do this)
Make sure to follow the instructions on the person who created the theme. Most will tell you to use ROM Manager to install the theme.zip. Unless they specifically tell you to rename it to update.zip - don't.
2. If I want to install a new ROM on my phone, should I flash with Odin back to Eclair 2.1, re-root, and install the new ROM? Or can I do this from ROM Manager with a backup of my Apps on Titanium Backup (and how do you export this to work on new ROMS)?
It is highly suggested that you ODIN 1 Click back to stock before updating to a new ROM. If it is just an update then sure you would be able to install over the top of the existing ROM.
Although you "could" install a new ROM over the top of the "old" ROM - you could very likely have issues - starting fresh with going back to Stock prevents you from having any issues that might arise over flashing a new ROM.

Baseband of modem has nothing to do with compatibility of themes. You could be using a jpy or jk3 Rom framework base and be using the same jl3 or jk4 modem which is what is reflected in baseband version under about phone.
If Rom developer is nice they will reflect framework base in the build number, otherwise they usually say in the op for the Rom.

Aha I stand corrected.
Although... before all the modem mix/matching started happening - it was a decent way to check what you were running.
Spose you would have to check the chef/dev before figuring it out like the dood above me said

[Q] Speedmod + Stock Froyo, updating to Gingerbread

Hello guys.
Official Gingerbread is finally available on Portugal.
I have currently Stock Froyo + Speedmod installed on my Galaxy S, so how can i update to Gingerbread?
Can i just update and Speedmod will still work?
Or should i install a stock kernel, then update, then install the Speedmod (Gingerbread version)?
Or i shouldn't update at all?

i'm interested in this too,i'm in the same situation (froyo+speedmod) and i'm quite a noob
is there someone who can patiently give us an hint about that? also about a good battery life gingerbread rom?

This is what I did.
1. Disable any lagfix - convert back to rfs (very important).
2. Back up all apps, contacts, data, photos etc from internal memory. Use something like Titanium backup or Mybackup pro.
3. Update through Kies for an official update.
4. Install latest Speedmod kernel for gingerbread (not Froyo version). Use odin.
5. Install superuser from clockwork mod recovery.
6. From recovery, do a factory data reset (make sure you have everything backed up first!)
7. Restore previously backed up apps, data etc, sync with google calendar.
8. Redo lagfix from recovery (convert to ext4).
Battery life at first seemed all over the place but has now settled down and is similar to Froyo/speedmod.
The phone is smoother and faster to use.

Thank you a lot!
That's exactly what i'm going to do!

thanks colin! 1 thing: i read somewhere that if you deleted some bloat app from operator (e.g. o2) you wont be able to update from kies anymore. is that true?
my phone it's not a locked one but anyway i think i always got o2 apps on it (which i unfortunately uninstalled instead of freezing it) and carrier-related updates.
am i going to have any kind of prob in the process?

If Kies is showing that there is an update available then I think you should be ok.
If not then it is a case of flashing the whole firmware with odin. Open phone dialer and enter *#1234# and you will see the firmware details you are on now. It is worth making a note of these so you can reflash your current firmware if there is a problem.

okidoki i'll try that!
update:
PDA:I9000AOJP5
PHONE:I9000AOJP3
CSC:I9000VIAJP3
pretty old looks like o2 release. being my phone unlocked i never understood why i got o2 releases on it
so when i am not able to upgrade by kies i should reflash stock thru odin.
what parameter (pda/phone/csc) i have to look at to get the right firmware?

Everything is working better than ever, except for one little thing: The GPS.
Today i turned on GPS and tried to use my navigation software (CoPilot) and the GPS signal just didn't fix at all!
I ended by not using it, but i don't know why it doesn't work. It always worked wonderfully well before this update...

Make sure you can get into recovery mode first. Power button, volume up and home pressed all at once. Let go home button when Samsung logo appears.

ok thanks for the infos! i'll do it all when i can have a bit of relax,i am relocating so i need a working phone during these days

so i did it then!
flashed darky's resurrection 10.2 and then updated to doctorz rom jvt leaving ext4 enabled with no probs: another phone

New to rooting

I have a Samsung i9000 which I have rooted with super one click details of my phone are:
Model: GT-I9000
Firmware: 2.3.5
Baseband: I9000NEJVB
Kernel: 2.6.35.7-I9000NEJVK-CL649158 [email protected] #2
Build No.: GINGERBREAD NEJVK
My question is this Can I flash this phone with any kernel or does it have to be specific to any of the numbers above (which I do not know what they mean) and if it does have to be specific could someone please tell me which kernel/s are compatible
Many thanks in advance

If you want root with proper CWM recovery you will most likely need to flash a kernel with Odin.
SuperOneClick gives you root for things like apps but you generally still have 3e recovery and you end up with signature failure whenever you try flash something from CWM.
In terms of kernels the easiest one which is closest to stock is CF-Root.
http://forum.xda-developers.com/showthread.php?t=788108
You generally want the same cf-root kernel as the last three digits of where it says gingerbreadxxx.
The rest of the instructions are in the first couple of posts. Fairly long but if you just read it slowly and go step by step its fairly easy.
Once you have flashed this you should have the correct recovery to flash other kernels & custom roms.
NB: Before you start all of this make sure to back up your phone. I would recommend connecting phone to pc & copying entire internal sd card straight to a folder on your pc. Also make sure to back up EFS folder. This is where your EMEI number is stored and you will want this if something goes wrong.
From Cyanogenmod Galaxy S wiki page:
Before you do anything — Make a backup
Don't forget to back up your data. If you have synced the device with a Google account, then the contacts, calendar, Gmail, & select other Google-related data will not be lost and will come back after the next sync. However, you should backup anything you want to keep that is not stored on the SD card:
SMS/MMS messages, Call Log, Bookmarks, Applications; use Titanium Backup or the Astro File Manager, for example, Any application data not on the SD card.
It would also be a good idea to backup everything stored on the SD card in the rare case the SD card must be formatted to resolve any major problems.
MyBackup Root, SMS Backup & Restore, and Call Backup & Restore are all free applications that can assist with backing up your data.

Hi, welcome to XDA man
Firstly everything scubadude said above is fairly important
Secondly; well it really depends on what you're looking for mate. If you just wanna upgrade your kernel (and by the sounds of it you dont really know what a kernel is, or what it does) then flashing a kernel only does so much on a standard rom. Flashing CF root kernel gives you proper root for root apps and clockworkmod (CWM) recovery so you can flash addons and suchlike.
However people usually root their phones so they can install a custom rom, which can improve speed, battery life, functionality and a ton of other things, and that's when people start looking around for different kernels which complement their current rom.
Just wanting a kernel with your stock rom doesn't make a whole load of sense. A ROM is what'll improve your phone.
If you want all the benefits of rooting, i'd suggest looking for a new ROM and flashing that.
If you're unsure of what rom to flash, read around in the i9000 development forum and read through different roms features. You could flash an android 2.3.X rom which would be a gingerbread (GB) rom or an android 4.0.X rom which would be an ice cream sandwich rom (ICS)
Dont ask which is the best rom for GB or ICS please, there are a billion threads like it, and it always comes down to this; read around, look at the features each rom gives, look at any bugs they may have (ICS roms probably have a few bugs here and there where most GB roms are completely stable) and decide if said ROM is good for you.
If you want a very stable, very fast, decent battery life and easy to flash GB rom then i'd suggest Gamerzrom. I'm running it atm.
However the dev stopped developing for it, but i can link you to ALL the files you need to flash the rom and a set of instructions if you'd like. I have a copy of all of them because i flash new roms but i usually go back to it anyway.
Definitely read the development section, you'll find something that sounds good for you.
Oh and for your information;
ICS > GB
and for GB firmwares, in order from newest to oldest, all 2.3.6 firmwares;
JW5>JW4>JVU>JW1
(those last two may be mixed up)
Most GB roms are on 2.3.6 now so it helps to know the above.

Thanks for the reply guys very much appteciated

As mentioned there are plenty of threads out there asking about ROMS & for every ROM there are going to be people that tell you the one they are using is best. If you are going ICS there is a nice easy tutorial here.
It is for Team ICSSGS. It is an older ICS ROM but development has been slow lately so while it is still good it is running ICS 4.0.3 while the newer ROMS are all on ICS 4.0.4. Having said that it is still a great tutorial & rom to get you started. It goes right from all the files you need, to getting a stock rom in case things fail to flashing ICS. Once you done everything in this tutorial you will be in a good position to start flashing & testing roms to find the one you like.
Oh yes if we have helped hit thanks.

Root is essential if want access to the system of your phone(elusive folders).
Then u can tweak kernel(eg.voltage control or mc tweaker)and improve GPS(GPS aids) or backup your apps and settings with titanium backup.all these are apps u can download from android market.
These are good reasons to root your phone.
If u flash cf-root kernel u will have many options to tweak your phone,because it support init-d(all custom kernel's support this).like supercharger v6 or thunderbolt tweaks this will improve your phone greatly.but u need to READ a lot before going down this road.
Anyway good luck and don't be afraid to root.

ok i think i may have screwed up my phone i flashed the cf-root kernel and phone rebooted. it has now been stuck on the boot animation for an age( blue flashing android word) is there a way of getting it back to stock nejvb. please help this is my only mobile

sorted it thank god found threes firmware etc.

Glad it's sorted

Go to settings/about phone and check your build,then go to cf-root thread and find a kernel that matches your build and flash that.
But make sure that it's the i9000 thread and not the i9100.
There is a MOBILE ODIN,that is quite easy to operate. If u already got root u can flash almost anything.search for it, it's made by chainfire(cf-root, yep same guy)
But u need root to operate

time to do my rom
ok managed to flash my kernel with the cf-jvb kernel. what i would like to know now is "can i now just flash a rom, and could u explain what a modem is and do i need one or is it included in the rom" i am wanting to speed up my i9000 so could someone suggest a stable GB or ICS rom.
many thx in advance for all your help so far

I have just noticed that this new kernel will not allow Wi-Fi connection it will turn on, scan, wont find my connection and then turn its self off. Have I done something wrong or is it just the kernel that doesn't allow it?
Sent from my GT-I9000 using Tapatalk 2

According to your opening post. Your build is jvk not jvb. Jvb is your baseband. Which you change depending on where in the world you live, it will make your phone have a strong signal. For example my build is jw5 so I use a root made for jw5. I use kg3 as my baseband because it is the stock bell Canada modem and gives the best signal. Root with jvk not jvb. Gl
