HELP installing custom rom please - Galaxy S II Q&A, Help & Troubleshooting

Hey all.
After reading about the brickbug and failing the eMMC test, im a little confused as to the safest way to root and install a custom rom.
I am currently runnning ICS 4.0.3 with I9100TDULPB kernel on an aussie vodafone branded device.
Do i simply use odin to flash a stock samsung JB ROM, then flash Philz or Siyah JB kernel for root+cwm, then custom rom install via cwm?
I would also like to retain the option of flashing my carrier stock image incase of warranty purposes.
Cheers

Exactly !
PD: Remember to follow the installation instructions on the rom thread, otherwise u'll end in nasty bootloops

Thanks for the quick reply
So this will ultimately allow me to odin flash back to the stock ICS Vodafone Branded ROM later down the track?
Cheers.

[Q]Stock ROM

Recently , i have been watching some Cyanogenmod 9 ICS 4.0.3 ROM video and it seems to be cool. Well my question is if i flash the Cyanogenmod ROM , can i re-flash the stock ROM that i had?
And is it safe to flash a custom rom?

Cool as in not overheating ???
a wipe and flash of stock rom will remove custom rom .
Root and custom roms void warranty and have a slight risk of bricking the phone .
But are usually recoverable .
You need to read the faqs and guides and understand the CM9 instuctions first .

to flash cynogen rom first u have 2 root ur phone please find the thread in original devlopment section regarding the same
u can reflash ur stock rom by dwnld the releavant .tar file adn flash the same thru odin
You can re-flash the stock rom, but just be sure to know which one is your stock rom. Go to settings, about phone and record the info there to be safe. Also back up your current rom using CWM.
There are always some risk in flashing a rom. Some people dont read instructions and cause problems on their phone, some people flash a rom not built for their phone (i9100 VS i9100G), etc.
Yeah i have rooted my device with cf-root. Thanks guys , i'll read some guides about cyanogenmod and flash it.
If your are currently on GB stock rom, Cyanogenmod developer recommends to install ICS bootloaded first,
You should be able to reflash your Stock ROM veriosn from ODIN, as well as custom roms from CWM...
What is bootload? o.o
My current firmware is ICS LP7

No they say to have below some specific ics boot loader, no mention of upgrading your gb boot loader, unless they changed it.
Plus I yet to had any issues with the latest ics or gb bootloaders..

I think he meant boot loader.
But since you already have ICS, you won't need it. Just take the latest CM9 nightly (or ROM based off it), and flash (you'll have to wipe cache data and dalvik too eventually). Make sure you make a full backup of your current stock ROM through CWM as well.

I refer this guide actually : http://forum.xda-developers.com/showpost.php?p=20841817&postcount=1
I dont know its outdated,
as others are sharing their experiance that you could flash CM9 straight away from your CWM since you are already on LP7 with ICS Bootloader.....
I don't get it... What is a bootloader?. I mean when i flashed with ICS LP7 i didn't put a file on bootloader. I just loaded the PDA .tar file and flashed it..
Soo that means that i have to reflash the stock rom with bootloader?

I dont know the ICS package you flashed had an ICS Bootloader already...
I just gave you the link for Original CM9 developers guide...
Just wait for others recommendation who have already flsahed CM9 from CWM....
Hmm thanks . But i have read in the guide that i can flash it with odin , do i still need the bootloader?

Flashed Using Odin, Want to Install JB... Now what?

So real quick....
I rooted my phone with ODIN last night, so I'm still running AT&T Rom and Stock 3e. I am trying to get JB installed but don't know where to go from here. I need to get Clockwork Recovery right? If so, how can I get that on my phone? I did read I should not used ROM MANAGER!
Sorry for the stupidity! I got JB on my last Galaxy before it broke I'm just confused because I did it a different was last time. Thanks for the help!
just flash a custom kernel with ODIN. That'll give you CWM recovery. then you can flash whatever you want.

Ok, is Odin 1.85 sufficient (or is there a newer one) and then can I just flash it with Siyah 4.1.4?
IDK much about Odin. But if it worked for ya the first time it should be good.
for the kernel, you must find one in a format Odin uses and not in the normal .zip which requires CWM recovery to flash.
Right now .tar is the only one that comes to mind for Odin.

I would flash a kernel that is compatible with whatever ROM you have currently. Then flash a JB ROM from CWM . Flash Siyah after you have JB if that is the kernel you want. I think you would get boot looped if kernel and ROM are mismatched.

Okay cool. I know this might be asking a lot but can you just link to me a Kernel that will work with the ROM I have? It's still the AT&T Stock Rom 2.3.4 with Baseband I777UCKH7 and Kernel 2.6.35.7.

Take a look at the guide which is the top link in my signature. It will give you a little more detail on what you want to do, and has links to the available Gingerbread kernels.

the only point in flashing a kernel compatible with a ROM, would be if you wanted to boot into the ROM.
Yes, flashing a kernel meant for a different version will most likely bootloop.
You can flash any kernel you want if you have no intentions on booting the system.
Recovery inside the kernel has nothing to do with what ROM your running. Will always be able to boot into recovery. Or **** broke
I give you lots of credit for reading not to use rom manager!

If you use Mobile Odin you can flash a custom kernel that will install CWM and then flash a custom ROM with CWM. I do this so I do not mess with the flash counter.

It sounds like you're taking the same route I did to root my phone. I first flashed a rooted, stock ICS ROM, then I flashed the Siyah kernel using Mobile Odin, then I eventually went on to flash a JB ROM (SuperNexus) using Mobile Odin. I'm sure I could have skipped that step of flashing Siyah because SuperNexus flashes a CM kernel anyway, but I kinda didn't know what I was doing.

Can i get a conform instruction on how to do this?i prefer not to do this with odin..because i already have a custom recovery...my recovery is CWM 5.0.3...do i need to upgrape my recovery first?
So you want to flash it via CWM, that's a completely different question.
You can also search for that.
Don't wanna flash with odin?
Mobile Odin might be the best tool for you.

1. Stock rooted deoxed rom 4.1.2 <<< -- to install this i need CWM for JB
2. Root on stock recovery <<<< -- to install this i need stock rom and stock recovery
3.CWM on stock recovery <<< --- to install this also need stock recovery
-stock rom and recovery mean using odin...and i dont want to use odin...
From all thing above..i need to know how to do this with ICS CWM that i already have....IF there is anyway pls let me know...

Check out Mobile Odin.

Well if you want to flash a official stock rom then you can only find them on sammobile.com and only way to flash it from odin. After that you can use Philz to install CWM if you want.
Hope it helps

i9100 Rooted but no CWM

Hello everyone, greeting from Turkey!
First of all im a newbie for android rooting and romming etc. I ve always used stock roms since ive got this phone. Now Im running a I9100 (int.) with stock Turkish 4.1.2 (XXLS8) on it and i ve rooted it via superuser.zip with my stock recovery.
What i want to do is to install CWM and want to flash a RELIABLE and Long Battery life rom. Are there anyways for me to install a CWM without using odin (via stock recovery). And can you please suggest me a good rom for daily usage. (i want to use vanilla android btw [just like nexus]).
Thank you for your helps.
I don't know much about roms/kernels for the international version, but you will need to flash a stock kernel with cwm and then just choose a rom from your development thread and follow the instructions, don't forget making backups and reading a lot, you can start from flashing cyanogenmod.

As i said i dont know about international version kernels, but it should have a tag like "stock kernel" or something like that if its for stock, just install it and you will have cwm, if its not stock it wont be installed anyway.

You can flash a kernel for stock roms via stock recovery, you don't need to use odin, just read the instructions.
