You can flash any rom on top of your current setup unless mentioned otherwise in rom installation instructions
if it says "[ROM][XXBLG1][12Jul][V1.6] WanamLite Smooth,Stable & Battery Friendly" do i need to have XXBLG1 firmware or it means it is based on XXBLG1 firmware or any other FW unless stated otherwise?
You will just have that modem when you flash. If the modem isn't good for you u can flash another

Unbranded Danish stock rom

Hi
I couldn't find any unbranded danish official rom for the Samsung Galaxy S3 international version on sammobile, are some of you having one you could share ?
I need to flash my phone back to stock after rooting it, because I need to use my warranty because of some hardware problems.
So if I can't find any Danish unbranded stock rom, and I use a UK stock rom to flash back, would the samsung rapair center see that I have flashed a different rom than the official Danish one ?
Sorry for my bad English

Try CHECKFUS to download firmware .

How to get Official JB Update (when it's out)

Hello
I just wanted to ask a question about the official jb update from Samsung.
I'm currently running a custom Omega ROM, if I want to change to the official Samsung JB, when it comes out, how would I proceed best?
I tried to find out how to revert to Stock, so I could just do an OTA update, but I don't have an original Stock Firmware Nandroid Backup..
I live in Switzerland and had a Swisscom branded Phone, which was not locked.
What do you think?
**EDIT**
or the leaked JB test firmware
You can find your firmware at sammobile.com. Just flash it with odin.

If from OMEGA rom , do you want to go to a rom stock samsung , run before a nandroid backup and save the folder EFS , performs a wipe date , factory reset ,then after with ODIN flash rom stock samsung , if remains in boot-loop repeat a full wipe from the recovery ....
I would wipe phone and install JB as its a new OS not an update .
jje
there's still something i don't get..
i do still have the ota option on omega.. is the firmware seperate, which would mean that i would be possible to be on omega rom and have a stock firmware, or do i also return to stock rom when flashing the firmware?

No, because Omega is a costum rom,it's based on a stock firmware and kernel but, it's a modded firmware so you must wipe everything and flash with Odin if you want to go back to a Samsung Stock firmware.

HELP!! How can I get my base firmware version

I'm a newbie here and if I've said something inappropriate, sry first
I've a GT-i9300 with CM10: "10-20120907-NIGHTLY-i9300"
How can I get my base fireware version or something?
The only information I have is that its baseband version is "I9300XXLE9", nothing else can I get from Settings - About Phone
Is its base firmware "XXALE9" i guess?
Failed to *#1234#, and something else like that, only *#06# worked but no help for me
Thx~!
So you want your original firmware so you can put your phone back to stock? Download from sammobile.com.

Jelly Bean is not officially out for S3. The official firmware by Samsung is still ICS 4.0.4. Search sammobile.com for ICS firmware of your region, wipe your phone and flash through ODIN.
I have a question - if I have a stock German Vodafone SGS3, can I flash the JB leaks? It says they're designed to be flashed over Stock XXBLG8. It's okay if I flash my german phone to a uk firmware?

Yes. Make sure your model number is I9300. Do a cwm backup so that you can revert back if you're not happy with it.
