You are in the wrong forum this is I9300.

Find your original firmware on sammobile and save it .
Use I9305 firmware and mods and EFS backup not I9300.

Hi Folks
I am indeed a noob as the intro video to xda states. I am also aware that this post will annoy some of you. But i would appreciate it if you could take some time answering this
I have a few questions regarding flashing before i go ahead with this. I would very much appreciate it if you could oblige me with some answrs to the questions listed below :-
My phone is Samsung Galaxy S3 international version ( gt - i9300 ).
1.Will flashing to the poland release of jellybean result in me losing my APNs for mms and internet ? And will I have to reset those after flashing ?
2.Does flashing mean i void my warranty ?
3.will I get any future samsung bug fixes/ firmware updates/ any other updates from samsung after flashing ? 2nd part to this question -- since i am flashing to poland release .. will i get future updates from samsung when poland gets it or I just wont get it period
4.I have heard that if I reset my phone's CSC to the correct region after flashing , I might be able to get future updates from Kies. Is this information correct ?
5.If I manually have to update via odin any future updates, please link me to specific room in xda forum where any updates will be available as they come through
6.Do i have to remove my SD card and Sim card while flashing with odin ?
7.Will I lose any data/contacts/customisations after flashing with JB ?
8.How do i do a complete backup of the phone other than kies backup ?
9.Is anyone ,who has already done this, experiencing any troubles after updating to JB ?
Any answers and will be highly appreciated
Void warranty, contacts just sync to google. Contacts should stay, but sync it anyway. In case.
Customisations, not sure which customising you're talking about. Homescreen set ups and app data should be intact, unless you wipe data through recovery or something.
In any case, root using the root methods provided, and do a nandroid backup in custom recovery. Backups up the entire phone (exc sd). If anything unsatisfactory, you can always restore. I used cf root to root the phone.
I'm in the uk and I've flashed the polish one, no problem whatsoever using internet. Haven't tried mms.
As for updates, sammobile.com posts all official firmwares on their site. I9300 general forum also has a post with any firmwares. I'm not sure about automatic updates but you'll probably get the firmware posted on the forums before you get any otas so I haven't had the need to check this.
You can keep your sdcard and sim in the phone when doing any of this. Had no problem using the phone after update.
Hope this clears any questions you had. Enjoy your jelly bean

thanks
few followup questions :-
1. I do not want to root my phone. Is there a way to do a complete system backup without rooting. If not can i flash it back to stock ics firmware if anything goes wrong?
2. Could you please link me to sam mobile firmware site you are referring to
3. will reflashing to stock ics unvoid the warranty ?
There are ways to un-root your device and make customizations nearly undetectable
If done correctly rooting and flashing your device has a pretty low possibility of hard-bricking your S3
Softbricks may occur but with Odin/Recover Menu you're prettymuch good to go

Your questions seem to have all been answered above, but I just want to add that in addition to a Nandroid backup, you should specifically back up your EFS and store it safely somewhere on your computer.
This contains your IMEI, and you will be seriously screwed if it gets messed up.

Thanks a lot. I flashed my phone this morning. I am pleased to inform that i did not lose any data or customizations ( homescreen widgets / apps orientation etc)
I'm glad you flashed without any problems. If you're worried about things like your APN settings, your contacts, your text messages, etc... you can use MyBackup Pro (which I use, you can use it with or without root) or Titanium Backup if you're rooted (which I've never used so I can't really speak about it).
Can I unroot my I9300?
Hey, I plan to root my S3.
I had this is in mind. Can I unroot my I9300 in the future for warranty if I root it using CF-Auto-Root?
Help much Appreciated.
Thanks in advance.

Hi guys,
i know most of you are thinking now why i dont search or google or something else but really i cant do anything about this.
I am new to flashing and rooting and i rooted my s3 ella i9300 version with the samsung toolkit v 7.0 via odin.
Now i would like to instlall this ROM: http://forum.xda-developers.com/showthread.php?t=2106471&nocache=1
But srsly, there is no good tutorial for newbies. i cant understand why the developers never try to help us noobs in such situations like this.
So please can anyone help me out? I went into the download section of the ROM but there are so many files i dont know which to take and download...
Thanks in advance
Full instructions are on the website, linked in the OP of the slim thread which you no doubt read

Yes but you would be better not flashing that rom . But spending time reading the basics first as you are lacking in even the first steps .
Noobs are expected to read first flash last this is a developers forum for developers . Those that don't bother to learn the basics are not going to be spoonfed .
So seriously you read the posted stickied faqs and guides or suffer a bricked phone your choice .

Hi,
Just need some clarification please
I will probably would want to install a custom rom like I did for my S Advance.
1) Should I choose one from the "Galaxy S III Android Development"? (I assume this forum includes devices bought in the UK?)
2) And the type of ROM I'm looking for is one that doesn't really change anything much from stock...but makes my phone run quicker and cleaner (by removing unnecessary applications). It looks like there is one called Android Revolution HD 40.0. Would anyone recommend this?
Thanks.

I have looked around for a while but cant seem to find anything clear. So i made an account.
Will i be able to root my S3 (i9305) and install a custom rom?
Got the phone from T-Mobile UK on contract. I updated to 4.3 when it came through ota.
Sorry for asking :fingers-crossed: but thanks to anyone who replies.
Hello Heych123 and welcome to XDA. First a fair warning .... you will get addicted to this site :silly:
Ok, rooting the S3 I9305 is prety easy, altough i'd like to advice you to read read read before you do do do.
For rooting your device, use / read this thread
[GT-I930x/T/N][SHV-E210*][SHW-M440S] CF-Auto-Root
After you've succesfully rooted your device, i'd advice you to use / read this thread
[APP][4.0+][ROOT] SA Manager (EFS, TA backup & restore)
Lastly, or maybe better yet, start with reading the first four pinned threads on this page.
My last advice would be to keep everything (downloads and stuff) nicely orginized on your PC by putting everything in clearly labeled folders.
Like a folder for root-files ...... and a folder for ROMs ..... and a folder for backups ...... and so on.
Good Luck and have fun !!! :highfive:

Hi
Just managed to get a dead S3 into download mode with a GPG Boot cable , as a iPhone user (please dont boo me , I'm jailbroken at least) I have very little understanding of the Android ROM system , I'm unable to find matching files and have to wait about 10 hours to download every one.
If someone could tell me the right files I need to flash this phone back into stock rom I'd be very grateful.
Its a I9300 UK Vodafone with the stock OS it came with , I'm assuming 4.04 ?
I'm not sure which version of ODIN I need , nor either the .tar all in one or .pit / csc / phone / modem files.
I dont mind waiting a week to download these files so long as they're correct.
If you could tell me this it'd be much appreciated and If I can work out how I'll tip you in some xda-developers forum way.
Many Thanks :good:
Keir Lawson
Follow the sticky guides, don't post questions in general forum.
Help
If a mod wants to move this to the relevant section of the forum that'd be great.
The sticky guides are unclear and overlapping , many link to hotfile which now dosen't exist and they each say you need a different rom or version of ODIN , any help would be much appreciated and as said rewarded.
16GB I9300 UK Vodafone , Fixed using GPG Boot cable , clear instructions + link to files on how to completely re-stock it.
(Any version of android , don't mind if newest or not jsut want it to work)
