[Q] I want to flash a custom rom

Hi
my phone is a galaxy GT-I9000
PDA : I9000BGJP3
PHONE : I9000BGJP2
CSC : I9000XECJP2
Build Info : 2010, 11
it has froyo 2.2 , Movistar Spain stock rom
it is not rooted
and it has recovery and download modes
Now I want to flash a custom rom (cyanogen or darky's)
i have read a lot of guides and tutorials but i'm still a little confused
So I want to know if I need to flash the firmware first, then only after that, I install the custom ROM ?
Or do I directly install a custom rom without flashing a new firmware ?
thanks for your help

Hi ziko360, since it sounds like you are new to custom roms I recommend you first try darkys rom.
If you are wanting to flash darkys v10.1 then yes you first need to flash the jvh firmware then flash darkys v10.1 after.
If you dont want to flash a custom rom you could always flash jvo from samfirmware.com then just flash a custom kernal instead.
Edit: Iv just noticed you asked in another post that you wanted to install the voodoo lag fix. If you have done this, then remember you must first diable the lag fix!

You should create a file or folder named disable-lagfix and place it in the voodoo directory on your sd card and reboot the phone. Or if that's too complicated you can Download from the android market the application Voodoo Toggle reboot Button - just hit the button so that voodoo is off and reboot. Also, in the app Voodoo Control there is option to disable voodoo lag fix

Ok thanks alot. i'll check this soon..;-)

ok thanks a lot
It is actually Darkys 10.1 that I have chosen
I've read the tutorial on Darky's website and it explains everything (flashing jvh firmware, disabling lagfixes... )
thanks for your help

The fix is flash stock Froyo with pit and repartition checked via Odin if rom breaks your phone .

[Q] Lagfix and root working on JV6

Hi all
finally i am on an official 2.3.3 JV6 rom
now i feel its lagging abit
i used voodoo lagfix on my previous rom
now i am searching for any lagfix or kernal (with root)
for my mobile (JV6)
please can anyone help me which one to use
Thanks in advance

Look in Android Development subforum here. You'll find custom kernels to do what you want.
eg. SpeedMOD, FuguMOD, etc.

which one do you prefer for the JV6?
Just want to know you opinion

Today's GB rom is smooth enough, no lagfix is needed.
If you need ext4, the famous Voodoo or Speedmod also is the solution for you.

Help with jv rom versions.

Hi
I currently have an vodafone unlocked galaxy running bujv9 rom. and cf-root XWJVH kernel. phone is rooted.
I been looking at kernels which support voodoo sound and other stuff as my one does not.
How do i go from a jvh rom and kernel to say a jvr kernel and rom which supports the voodoo stuff.
Is it a simple wipe then CWM flash new rom then odin jvr kernel. or other way around. Not sure.
Sorry still learning galaxy flashing. well different from HTC flashing.
Cheers.

If you want to try latest rom and a kernel with all features flash stock JVS in odin and then flash Darkcore 4 or Semaphore 1.7 in odin

Your desired rom should have kernel so no need for flashing twice.
You will probably get away with factory reset and cwm flash. Any probs you may have to flash stock first.

There are apps that will do this, but may not work properly (depending on a lot of things). If you're unsuccessful with the app, or if you'd rather another way, the main to go about it is to flash a kernel that is already rooted.

Thanks for your reply, my problem is that i can't find the right cf-root kernal and also because phone locked to network my build number is bujv9,

Flash the stock jvX that you want first then flash the kernel from odin as pda,safe way

[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?
http://www.youtube.com/watch?v=6lO3Y86N2p0&feature=BFa&list=FLqhM0qK4aVsLmWAA_YYhBCA&lf=mh_lolz
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] About Semaphore kernel flashing

hi,
i have stock Galaxy s i9000 with 2.3.4 XXJVP.. i want to install Semaphore kernel... hoping it will improve overall performance and give even better performance with games like asphalt 6,,..
all i want to know is that can flash it over my stock with SGS kernel flasher??? or are there any other pre requirements for it???
or is there any better kernel for playing games lag free??
THX

Ny reply??? :-(
Sent from my GT-I9000 using Tapatalk

You can install this Kernel via Odin easily, and YES it will improve your overall performance
Ps.:Flash Gingerbread 2.3.6 its really good

Remember to disable lagfix.

The best kernels for playing games on gingerbread roms are the Semaphore Bigmem kernels. But if you really want lag-free and super smooth gaming, you should consider using froyo 2.2.1 roms.
Oh, and to answer your question, yes you can flash the kernel using the kernel flasher app, but it's probably safer to use Odin.

Thx fr the replies...
I would want to know which version of semaphore to download..??? Thrre are two versions.. 2.1 & a bm version ...

How do you do this?

you should download the RIGHT kernel, if you have JVP download the kernel for JVP ,not the kernel for JVZ.

for gaming and performance TalonDEV kernel is the best

Semaphore kernels link
Hey can someone give me the link to semaphore jvt 1.9.2 kernel?
TIA

If you dont know, you probably dont have to. My guess is you have never used lagfix or ext4. if you think you might have, go to cwm recovery - shut down phone, hit the 3 button combo (power + home + volume up) until samsung galaxy boot screen appears and leave the buttons immediately. in the recovery mode, go to advanced and see if theres any option for Lagfix or Ext4.

No you should not do that. Use a kernal that is meant for your firmaware. If you want to flash semaphore 2.1.1, first upgrade your firware to JVZ using Odin. The are plenty of links to this firware under General.

This could be a silly question
As per the SamMobile.com the JVZ released on November 2011
so how comes this forum (http://forum.xda-developers.com/showthread.php?t=1112908) postdate is 6 June 2011 ?

Hey sorry have been away. Well you should be able to flash a kernel but there arent many out there and i am a little wary of flashing a kernel as they are all in a very experimental stage. Moreover, i find teamhacksung's (pawitp's) build to be more stable and the aries kernel was a whole lot more better. hated glitch the moment i flashed it.
Happy flashing...
