[Q] Several questions on how to flash a Galaxy S3

Hey guys,
I want to install a custom ROM my GS3 but before I just want to ask some questions on how to proceed.
My phone is currently running on the SFR (French provider) firmware BUALF1 and I want to get rid of the software overlay (13 app which I can't uninstall).
So if I understand I have to flash my phone with the stock firmware XXALE9.
Then I have to root my phone (I'll follow this tutorial : http://forum.xda-developers.com/showthread.php?t=1701770).
Finally I can install the custom ROM of my choice.
Is that correct or did I miss something ?
Thanks !
ps: Sorry for my English.
If you like to install stock firmware then there is no need for root.
Download the stock firmware and flash it directly via odin. I'd suggest you to read Intratech thread to know all about flashing..
《tapatalked from galaxy s3》
Ok thanks,
I already read Intratech thread but I just wanted to be sure everything was good since it's my first android mobile phone.
If you just want to remove the bloatware you don't need to root you can just flash the regions firmware.
But most custom ROMS do this anyway so if you are going to root and install a custom ROM their is no point in doing this. (You can anyway it will just be a waste of time) Happy Rooting
Wow ok indeed I was going to waste my time so I'm just going to install a custom ROM.
Thanks !

if you wan't to upgrade you don't need to unroot, just flash firmware trough odin (addicted to your country)
also to unroot just flash with oding (stock firmware) and wipe data/factory reset and done,
threads are everywhere in general just look around

Since this topic is started might aswell use it instead of making a new one...so my question is:
From what I've read, in order to install CM7.2 on a Galaxy S2, you also need to install a custom kernel...so if I did all that, and want revert back to my original ROM and kernel, I just flash a stock ROM from Sammobile? Or the Kernel will remain the custom one (if so, how do I change it back to the stock one)?

Nope your kernel won't be left until you flash a Rom which has no kernel, but all Samsung roms out there have kernels inside the flashable tar or zip, you ain't smart if you don't provide a kernel which is made specially for the Rom

[Q] Downgrade from Gingebread to Froyo Samsung GT-B7510

I updated the firmware of my Samsung Galaxy Pro (B7510) to gingerbread using odin. Now I need to downgrade to froyo.
I have found the firmware at sammobile but I am not sure about what to do now. I mean, I know that I need to use odin to do it.
The thing is that I already have tried to downgrade it, and I bricked it, even I had to revive it using J-TAG.
So I don't want to brick it again so I want to proceed very carefuly and sure about what I'm doing. That's why I'm asking you before doing anything.
I have used this tutorial last time (when I bricked it):
aandroidapps.blogspot.
com/2012/06/downgrade-b7510-from-gingerbread-236-to.html
[the link to the tutorial is splitted in the 2 lines above]
It's a correct way to proceed? or should I do something different?
Thanks in advance.

You don't have to download from samfirmware which hosts using hotfile.com (which has been shut down as you've found). Look on AndroidFirmwares.net or Samsung-Updates.com, hopefully you can find a live link for the firmware you need.
