Hello.
I have had a GS3 for a few months now and a few weeks ago my friend showed me how to install the polish jellybean update for my phone (I don't have a polish gs3 but he said it was safe to do ) and it was pretty easy.
I have decided to use a custom rom now. I have already rooted my phone but before I install a custom rom I was wondering how easy it is to go back to the polish version that I have downloaded if I don't like it.
Thanks and hopefully this is the right part of the forum to post this in.

Thank you. If I want to try out different custom roms do I have to go back to official firmware first or can I just install a custom rom over another custom rom?
Hi,
You can flash a custom rom without going back to the "original version" (stock rom that came installed in your GS3) - Just keep in mind that you must do a full wipe in your device (data/cache and dalvik).
You just need to flash the CWM via odin and then flash the custom rom via CWM.
You just need to follow this instructions here (http://forum.xda-developers.com/showthread.php?t=1695238)
And than follow the instructions of your favorite custom rom to install it.
Cheers

OK, but he doesn't need to go back to the stock rom before flash another custom rom. To try another custom roms he only needs to do the wipes and follow the instructions of the custom rom to install it.

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?
Hi Guys,
I was wondering if there is somehwere I can download the Official rom from.
I installed cyanogen mod 9 on my S3 using clockwork recovery mod and it wiped my backup.
I have tried sammobile but the problem is I need it for version: I9300XXLH1. I am located in Australia.
While on the topic, I have a friend who is using a S3. Could I possibly install CWM and copy a backup off his phone?
Please help, I miss all my features haha.
The official stock rom does not exist .
Many official roms .
CHECKFUS is probably your best method .
Could I possibly install CWM and copy a backup off his phone?
Probably .

Why don't you just flash the JB rom with Odin that was released yesterday.
After that, go into stock recovery and do a wipe data/factory reset and you're good to go.

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.

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.

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.
