[Q] Rooting and Installing ROM on GT I9000

Hi,
I finally got a Samsung Galaxy S after finding a great a deal on it. I'm aware that there are several ways on how to root this device. However, due to that I don't know which to use.
Currently I'm running on 2.2.1 Froyo XXJPY with Kernel Version of [email protected] #1.
I'm not totally clueless about rooting as I've done it already on my HTC Wildfire.
Could someone please advise me which is the most up-to-date and safest method of rooting? Link would be greatly appreciated.
Also, I'm a bit confused about installing ROMs. I used to use CWM on my HTC Wildfire which was incredebly easy to do. Would it be the same on my Galaxy S?
I'm planning to test out MIUI, DarkysROM and such ROMs. Would these ROMs have the LAGFIX feature integrated in them as well?
I apologise if a thread like this has already been posted a thousand times but I just can't come up with a definite answer.
Thanks in advance.

I have a galaxy s Vibrant the I9000M and I rooted and unlocked mine today using SuperOneCick and then The Galaxy s unlock by helroz on the app market took a grand total of 6 minutes

Thank you! Now, that's one down.
Now just want to know about flashing ROMs e.g. MIUI, DarkyROM and such.
Do I need to root my SGS first to be able to flash custom ROMs?
I also noticed that you would also have to flash firwares and kernels. Do I need to this before flashing custom ROMs?
Thanks in advance.

In order to flash a custom rom you need to have clockworkmod (CWM) recovery.
and from that its easy
As for the newer rom's here, they are all 2.3.x, so in order to get from 2.2.1 JPY, you will need to flash a stock rom 2.3.x with bootloaders via Odin.
use this link to read about odin and flashing with it. its a great guide
http://forum.xda-developers.com/showthread.php?t=723596
to find stock rom's - they are in the general section. and custom rom's in the dev section.
read a little and after that have fun!!
And keep in mind every rom has its little guide, read those before you flash any.

Hi,
Many thanks for replying. Can I follow the video below made by a fellow XDA member direct from 2.2.1 to 2.3.4 via Odin?

So I will Download stock JVQ from Samfirmware > Download Odin > Flash a stock 2.3.4 JVQ > Install chosen Kernel with CWM > Flash chosen ROM using CWM.
When would I need root then?
Is that right?
This reminds me when I had my Samsung Tocco. Pretty much same procedures.

That is right... basically when you flash a kernel with CWM you get root access. it's one of the features of a custom kernel. some of them activate it on there own and in some you need to activate it your self from the recovery (very simple).
And all the custom rom's come with root access, so in following the steps you wrote, you will get the root access with the custom kernel, and again in the custom rom.

Thanks for everyone's help. I'm now running Armetris 3.6.1 with Semaphore Kernel.
Just a question though, with my phone rooted, lagfix enabled, flashed with custom ROM and such, can I just simply go back to stock ROM? e.g. JVQ/JVR using Odin without any problems?

It is suggested to disable lagfix before changing rom's and kernel's
I know some how would say it is not a must when you use odin, but i always disable it before doing changes. I like to keep it safe.

sorry for this nooob question....
new to the samsung gt i9000, do i need to create a gold card before i do anything else????
sorry to be a bit thick but im used to htc

Hi,
Thanks for the reply. I'm currently running on Semaphore Kernel but I can't find any Lag Fix option on my phone? There isn't any on CWM Recovery as well.
I thought when you use EXT4 and convert it, Lag Fix would show up but I found nothing, so I just converted back to RFS.
So, I'm fine to directly go back to 2.3.4 JVQ even even I have a custom Kernel and custom ROM?
Thanks in advance!

If you used the EXT4 app and converted to RFS then you have disabled the lagfix.
The lagfix changes the filesystem from RFS to EXT4. so when you converted to RFS yoh disabled it.
So,yes you are good to go.

Gold card?? what??

Also, If I were to flash a JVS Based ROM do I need to be on stock JVS and a JVS Kernel to flash it?
Once on I'm on JVS custom ROM can I just go back again to JVQ stock (Older firmware) without problems?
Really appreciate all your help Bork84!

Basically using odin you can change to JVS and JVQ no problem.
As far as custom rom, from what I know it does not matter on which 2.3.x you are, thay all have the same bootloders. so technically you dont need to be on stock JVS to flash a JVS custom rom.
but I am not an expert on that.
from my experience, i flashed to a JVR (2.3.4) custom rom via CWM from a 2.3.3 stock rom, and didn't had any problems.
So i cant give you a 100% answer

[Q] Custom Roms' compatibility with firmware and Kernels

Just a few quick questions please.
a) Will there be any problems installing a rom which isnt created for the firmware? Example if Im on 2.3.5 and I installed a Rom which is made for 2.3.6, will there be any issues?
b) I understand that most roms comes with its own kernels, so if Im installing a Rom which has a KKA kernel and my phone is on a KJ4, do I need to install a KKA kernel 1st before installing the rom?
thanks

1) Always, on any phone, when you want to install a ROM with different basement than yours, needed full wipe before.
2) never instal a kernel before ROM.First the ROM, after the kernel.all kernel threads in op, you can see if its compatible with your rom filmware version.

Sorry for the bump but I need little explanation on both of these questions though I have Galaxy SII. I think I don't need to make any other thread asking same questions.
Thanks.

I make sure I do a full wipe every time I flash a different ROM.
This is not the case for ROM updates. I only full wipe when the update tutorials says I need to.
And as said before, make sure you flash the ROM first THEN the kernel.
In the case of the G-Note, both AbyssNote and FM kernels are compatible with CF-Root custom kernel.

Hmm.. then is there anyway to backup your stock ROM without root OR you have to first root the device, back it up and then flash another ROM?

Yes, you can backup the stock ROM after rooting the device and installing CWM.

[Q] How to extract/make flashable odin rom

Hi guys, i have looked but cant find.
what i want do try and achieve is to pull the rom from my ace with all installed apps/settings that i have installed.
basicly i have AOSP Beta 1 over XWKS2 stock,
launcherpro
cyanogenmod setings
cm7.x gps patch
i have a backup made via cwm5 but this is just a retore folder.
i would like to create a fully flashable rom of my current rom/settings/patches.that can be used via Odin.
the purpose of this is so i can have my rom backed up and flashable, just like a stock rom, and so i can try other roms without having to flash back to stock then flash AOSP and then flash patches and cyanogenmod setting, wich is a bit of a nightmare "trying new roms on daily basis and having to flash back due to bugs or poor performance"
if someone can help me create a flashable backup in a noob friendly way i would be very greatfull.
i love my ace as it is at the moment, its perfect for me. it would just be nice if i could flash back to my custom rom in 1 flash rather than many + having to add all patches after,
this would be amazing if anyone can help.

Yes I'm still interesting to do that also from my S5830i

Odin is only for stock roms. You cant flash custom roms using Odin.

Flashing ICS Updates

Hi All,
This will sound a stupid question, i have flashed SpeedMod Kernal (K3-3) how to i go about flashing a ROM also?
I know most ROMS say how to perform but SpeedMod says no CWM or CIN9 roms?
Anyone help.

What I did:
1. Flash Stock ROM 2.3(choose your country from the Stock Rom topic) with Odin 3
2. Root your device
3. Install CWM
4. Install safe ROM (CM9 as example)

Nothing stupid about the question, but it doesn't belong in Development. I've moved it to Q&A. Please be more careful about where you post

So what ROM are you on now with the speedmod kernel? Stock ICS?
What ROM do you want to go to?

Currently on latest UK ICS 4.0.3 (Offical) rom from Samsung Kies software. Sorry should have stated before not on 2.3.6 anymore.
Any suggestions?

Okay, flash the Speedmod kernel in CWM. This puts you on a safe kernel with stock ICS.
Now, you can flash a CM9 variation of a rom or aokp or one of the other ICS roms that use samsung base.
Edit:
After you flash speedmod, boot up your phone and check settings, about phone, and make sure the kernel is speedmod. Let your phone settle for a little bit, maybe charge if it needs to.

[Q] What do I flash first, kernel or rom?

The question is really in the title, what do I flash first when upgrading from darky froyo to ICS, the kernel or the rom?
Thanks!

Follow instructions for the particular ROM you want to flash

They usually don't mention the kernel, only the rom :/

The kernel is pretty much always included in the.zip, if you want to change from the ROM kernel to another, then usually just a case of using a cleaning script, or manually clearing cache/dalvik and a couple of others (init.d & Ns tools usually) and flash away

upgrade 2.2 to ics
You have to burn GB stock-rom 2.3 with odin first !!!
after you finish you need gb kernel like semaphore 1.8 also burn with odin (give the stock root).
and finnely flash the ics rom you wont (with the dev Specific rom Guidelines)

Afaik you don't need gb bootloader to flash to ics, (see slim website) however it is a good idea to in case you want to revert to gb, but in that case it is easier just to flash the boot loader....see nitr8s ezboot thread

Hi, I know it's been a really long time of the thread but what I know ALWAYS FLASH THE ROM FIRST AND THEN THE KERNEL
