[Q] Need help understanding root, firmware, kernals and roms - Galaxy S II Q&A, Help & Troubleshooting

Hey Forum,
I was hoping you guys would be able to help me out. i'm coming from the HTC Legend and kinda lost when it comes to Samsung.
1. what is all this firmware info i keep seeing? is it just the firmware or do i have to match current firmware on my phone to the firmware of the ROM i want to flash?
2. kernels do i flash a ROM and kernel each time or is it all ROM's come with a kernel? or is it the same as HTC, once you find a ROM just flash it through CWM?
3. how do i get root? should i just flash CF-root and then flash ROM's from there?
I'm sorry for asking i know that all this information should be somewhere but most guides seem to be written with the assumption that you owned a Samsung device previously
A big thanks to anyone who can help
thanks,

No try any firmware a before b 3 after 2
2. kernels do i flash a ROM and kernel each time or is it all ROM's come with a kernel? or is it the same as HTC, once you find a ROM just flash it through CWM?
Roms are with a kernel Flash depends upon the roms instructions but most are CWM except for stock roms .
3. how do i get root? should i just flash CF-root and then flash ROM's from there?
Follow the root thread .
Root + CWM .

Flashing difference between Samsung and HTC?

Hi all, i'm currently with a HTC Desire and the procedure to flash a new ROM was first to flash a moded bootloader and a recovery from which you could just flash any .zip ROMs...
I'm not familiar with samsung, but I see that there is a tool called ODIN which you use to flash.
Can someone explain the difference? Will we always need a PC to flash a ROM or will be there a possibility to have a moded bootloader + recovery?
odin is to flash the .tar roms , mostly stock roms . In Galaxy s series if you have a hacked recovery like cwm 2/3 you can flash .zip roms also .
Diffrence 1%
We are doing the same but flashing the kernel + recovery with ODIN and then everything is the same
Also we are flashing ROM's with recovery, there is no need of PC, just to download the ROM's.
I'm not sure but, the bootloader is unlocked so, do we need to flash modded bootloader !?
Strange to me.

Мерси, колега.
this is a question, should have been in the general section.... wrong thread. pls read the rules before posting buddy.... & try to keep this forum as clean as possible....
there is not even a single element of development in this new thread.... user has a doubt regarding different ways flashing of ROMs between different brands.....
pls dont repeat the same mistake.... search the forum carefully first, then you post in an appropriate section if you dont find anything what you are looking for....

When you find the threads containing stock ROMs, after making sure you're getting it for the correct device, you'll find full instructions. There's no point me duplicating them here.

[Q] Which CWM version

Hi, I am running an ics custom rom from rizdroid 19100xwlp4-19100xxlps-19100luxlp1 and I would like to flash clockworkmod to my rooted phone via Odin but not sure which version I need. Any help please or advise please.
Alan
I use Siyah Kernel which has CMW 5.5.0.4.
you can get this kernel from here:
http://www.gokhanmoral.com
Thanks, do I just flash my phone using Oldi with the Kernal or is there anything else I have to do?
If your phone is I9100 international model, just put the Siyah kernel TAR file on the ODIN PDA and flash.....
How did you flash the custom rom "rizdroid 19100xwlp4-19100xxlps-19100luxlp1"
can you give us the link/thread for this ROM
Here is rizdroid's custom rom http://forum.xda-developers.com/showthread.php?t=1544487&page=416
I flashed used Odin, and my phone is an international 19100

my friend, this is not a custom ROM this is official ICS rom, after installing from ODIN, if you have followed the rooting method of the same thread instruction, (CF-root) you should have already a latest Clockworkmode installed in your Phone. no need of flashing again any kernels.
to checkout this just shut down the phone and press Vol-up+home+power button and hold for few seconds to appear the galaxy logo and keep pressing til it blinks and appear again then release.....you will get the CWM recovery
Hi all I did was flash the rom via Odin and I have an app that checks if you are rooted and it says I am but when I do the test that you said to do I get the Android system recovery not cwm recovery.

CF-Root for your firmware is not found so just flash Siayah from ODIN, make sure flashing file should be .TAR and selected from PDA.

Thanks mate all done now and all ok. I bought the app to clear the yellow triangle which worked also. Any tips you have for a rooting noob would be much appreciated.

The first thing you have to do after rooting is Nandroid back up and EFS back up of your phone...
Dont be after the shortcuts and tips, read as much as possible, There is no substitute for READING for COMPREHENSION.
these STICKIES will give you the knowledge about SGS2 from basic to the deepest.....
Try the N. E. A. K. Kernel with the modded cwm, works very well!

Thanks Keasbu for replying I have downloaded your Kernel I take it just flash my phone using Odlin but what about the Kernel that I flashed that Zaheedahmed gave me the link for. Also another question I want to play around flashing different roms to my phone do I need to flash a new kernel everytime.?

It is not terribly required to change your Kerenel every time you flash, the suitable kernel already packed by devs for their ROM is more than enogh for running the Phone...but further it is your choice to change the kernel after exploring the reviews and features of the custom kernels and decide whether it will give you any advantage or not....Also no need to worry about Clockworkmode it will be their already on the (allmost all) Custom rom.
the kernel which I suggested that time was mainly for you to get a Clockworkmode recovey and rooting which anable you to flash roms further
NOTE : Once you have already got Clockworkmode no need to use the Odin version of the Custom Kernels, just take the CWM version and put it on your SD card and falsh it from CWM recovery.
Thanks for replying zaheedahmed, what do you think of Keasby's Kernel is it worth flashing will I loose clockworkmode?

Sorry mate I have no personal expreance with any ICS kernels yet...
just read the threads....to find which is most popular and least problem giving....,.do you know the questian "Which is best" is baned in the XDA..
---------- Post added at 11:48 AM ---------- Previous post was at 11:42 AM ----------
No you wont loose the CWM, all the custom kernels are attached with a CWM recovery...that is the main goody of SGS2 kernels...
One more question if I flash a new release ics rom and it doesn't have a csc with xeu do I flash a csc xeu file at the same time as flashing the ics rom, will this work?

Sorry experts can give comments about the compatibility of such mix flashing....
But why are you so concerned about CSC, what difference is giving you XEU than others just for my information.
CSC can only flashed from ODIN, you will loose your root and you have to Root it again by flashing a Root kernel again...
Sorry I thought I needed csc xeu as I live in the UK
CSC not required if you enter network settings manually .

[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?

[Q] s3 I9300 not rooting...tried all method

hello devs,
i have an international variant GT-I9300 . I upgraded it with the ATO(OPEN AUSTRIA) . After this upgrade ,i was not able to root ...i used the CF AUTO ROOT , SUPERSU , and even mobogeine root method . its getting failed....
please help me devs......i would like to root it...either to get a stable international variant ROM.
If you intend to then flash a custom rom then don't bother rooting your stock firmware, all custom roms are already rooted.
If you want to stay stock then flash a prerooted version via odin, get a link for one on xda in general forum.

i checked the whole procedure of it as u told.... but while i am flashing CFROOT but it is showing "FAILED SIGNATURE VERIFICATION" . and the same thing for superSU ......
so...in case if i flash PHILZ RECOVERY or CWM ......without rooting........ will my phone get bricked ???...
Check out Cyanogenmod Installer follow the instrustion it will root and install the latest stable CM for your phone .
You are still missing basic knowledge, you can't flash anything with stock recovery.
Flashing recovery doesn't require root, but you can brick the phone if you don't understand what you are doing.
