Flashing its the same process, but a full wipe its highly recommended.

obviously I can't tell you yes or no , as far as I know you can flash anything above anything, the question is if 1) it boots up or 2) if it boots up anything works without FC when you come from another rom base, hence the advise to do a full wipe

Want to try out some custom firmwares, but want to be safe at the same time

Hi guys...
I have a galaxy s3 and up to this point I've been pretty satisfied with the original firmware...
However, I'd like to try out some of custom made ones, but since there's a big update on the way, I want to be safe doing so...
What I mean is basically this:
Can I somehow backup my stock firmware, try out some custom builds and then get the OTA update when it's available?
I don't really care about guarantee, but I'd really like the option to get OTA updates from samsung in the future (if I for some reason want to do so).
I remember an old post, where someone talk about this, but I can't find it
Please help me
Most definitely. You can find stock builds here in this forum and simply flash using ODIN to get back to stock firmware when you want to. Be advised this does wipe your data so have a good backup of it before hand.

And then it would be as my phone never were flashed and OTA and other samsung only stuff would work?
You will have to use triangle away or something like that to reset your flash counter if you want to send your phone to repair and make it appear as you have never flashed before but unless you break your phone, don't bother. And yes the other Samsung stuff should probably work.

If you flash your phone with a custom ROM for instance Resurrection Remix or Cyanogenmod you'd not directly be able to restore a stock ROM.
You will have to find one http://androidfirmwares.net that's for your region and flash it through Odin. Then you'll be able to update OTA and KIES.

i had the same fear of loosing my data and stuff so you can wipe dalvik cache and cache partition and flash omega ROM for ur S3 and welcome to perfection.
Ps. Flash with Siyah Kernel for battery craziness! ! !

You mean restoring from a nandroid? Because I was able to restore ICS whilst using JB - I did it multiple times.

Agree the advise given was plain wrong .
Nandroid restore a backed up stock rom yes yes yes .
The only but is that the backed up rom is of course rooted .

Okay... now I'm even more confused
Let me see if I get this right?
One way to do it would be to:
1) Download tools and rom (odin, CM and drivers etc)
2) Flash new cool rom
3) Donwload original samsung rom
4) Flash old boring rom back to phone
5) Use tool to reset counter (optional)
Now, my phone would like as if I had never ever rooted and flashed my rom
Is that more or less correct?

When you want to get back to stock firmware follow these steps
1.Download stock firmware for your region from
Www.Samsung-updates.com
2. Download triangle away from xda forum to reset your flash counter from
http://forum.xda-developers.com/showthread.php?t=1494114
3. Also download mobile Odin from xda forum from http://forum.xda-developers.com/showpost.php?p=22234918&postcount=7

Will I still be able to get official firmware updates from Samsung?

I'm thinking of flashing my phone with a custom rom, but I've just heard that an official Samsung Jellybean update is due to be released really soon. If I do flash (I've already rooted my phone) a custom rom, will I still be able to obtain the official samsung Jellybean update when it's released (via Vodaphone)? How would I do this (explain it in simple terms, as I'm still an android beginner)?
Also, is flashing the philZ kernel, the same as having the stock Samsung kernel, but with CWM instead of the stock recovery?
Thanks in advance,
You can flash a ROM but before you do make a Nandroid backup of the stock ROM before you flash it so once Sammy/Vodaphone releases the update, you can just restore the Nandroid and receive the update.

Is that how it works? You can just backup the stock rom with CWM, and then simply restore it anytime you want to get that original Samsung Stock rom back? Could you give a brief outline of the steps and requirements needed to make a backup and restore a "nandroid"?

Yes.
Just flash the JB-rom when it's released with Odin. Much easier. Or you could wait a little bit longer and flash a custom rom based on the official Samsung-rom through CWM.
Your question about how to make a Nandroid backup: don't be this extremely lazy and look it up/try it out for yourself.

"Just flash the JB-rom when it's released with Odin"
How would I do that? That's my main concern. Will the official Samsung jellybean rom be available on XDA for us to download and flash? Where would I get the official rom when it's released? I'm not looking for a tutorial. I just want to be sure that it's possible for me to flash the official stock rom when it comes out.

Yes, it will be available on xda, and on sammobile.com. Guides for flashing with Odin are not pretty hard to find on xda or google.

You can flash I9100 version, the diffrence between your device and ours is the baseband (modem). That being said, once you flash the jb ROM, you might have to flash another modem.

If u have a custom recovery .
Thn go ahead and flash the rom zip of any Android version with full wipe.
If u get status 7 error then u need to have latest cwm
Sent from my GT-I9100 using Tapatalk 2
Well maybe a little tutorial first
Rom=the firmware on your phone
StockRom=official (Samsung provided) firmware
CustomRom= unofficial firmware (rooted phones only)
Recovery= it's a surface in which u can install. Zip files and do other stuff like wiping dalvik cache etc. You have to differ between stock-/customRecovery
To install zip files you need a custom recovery like clockworkmod (cwm)
(to) flash something= that just means to install zip files via custom recovery
First thing you need to do is installing a custom recovery , depending of your phone model you can eventually use rom manager from playstore (gt-i9100).
If you have another model you may have to find another way to install cwm as I have no idea if it works on other models as well.
If you installed cwm successfully you now have to search for a rom which is fitting to your phone model, be careful, as flashing of a wrong rom can kill your phone forever.
To start the recovery you have to start your phone while holding the power, home and volume up button pressed. Once there it's a good idea to make a backup before flashing something.
If you have installed cwm through rom manager and have still stock rom, you only can start cwm by using rom manager.
Better wipe every data before flashing a new Rom otherwise you may experience a boot loop.
Alright guess that should be all for now, hope it'll help

Did your phone work normally on stock 4.3 or did you have to use patched modem and kernel to gain network?
Did the custom rom install a modem or use the existing?

I don't have a SD Card so where am I supposed to put the rom?
I guess full wipe will also delete the rom.
Also, should I root the device first?

If you don't have a ext Sd card don't try my suggestion! I would only ever advise a full wipe if you have a ext sd card just in case anything goes wrong plus like you said where would you put the rom. I would strongly suggest you getting a ext card no matter how small if you are flashing roms.

Now you have confused me even more! I thought you said in your previous post that you had connection on 4.3 stock rom if so why are you on 4.1.2 ?. Stock rom 4.3 is efs v2 and stock rom 4.1.2 is efs v1 if you have no connection on 4.3 then this is your problem you still have efs v1 which will not work on 4.3 or any of the newer roms please confirm that you have a signal on 4.3 stock rom.

Ok that's good it means you are on v2 efs which is good..I just needed to confirm that you had v2 efs I thought you might have been on 4.1.2 because of no signal.
I must admit this is a strange one because the asop roms,omni roms etc don't change your baseband which can effect your signal.There is one more option you could try use this patched modem >> http://forum.xda-developers.com/gal...ck-firmware-i9300xxemg4-t2377731/post43946365 << by JustArchi look at post 15.

Also your efs make sure you back it up preferably when you are on 4.3 stock rom.

Just want to add something
I used to install custom roms often. All of them worked perfectly fine
When I saw my flash counter it was 20+
So, I decided to use triangle away
Since then I am unable to flash any custom rom with working network successfully
