Appreciate your help ...
Thanks,

Couple of places you can get stock roms: Samfirmware.com, here (this site is better than Samfirmware IMHO) or with the PC version of Checkfus (search for it on Google/XDA).
Yes, you can install a stock rom for any region, but with one caveat. If you install a rom that isn't for your region, you may not be able to get future OTA updates from your carrier. Which isn't really a big deal because if your carrier does release a stock rom for your region, you could always download it with Checkfus & flash it with Odin (like almost everyone does on here).

[Q] Rooted using toolkit 5.0,need help

Hello guys.
Samsung Galaxy S3 GT-I9300
I was wondering if anyone could answer a few questions for me. I rooted my new phone using the toolkit method from this thread http://forum.xda-developers.com/showthread.php?t=1703488 and now i am confused about the firmware versions,and if the kernel was changed and such. I forgot to check all these versions before i rooted the phone,so have no idea if these are the original ones.
My phone is bought and used in Denmark,however the firmware suggests it is now a uk version looking at the country code could this be correct? If i look at this http://www.sammobile.com/firmware/?page=3&model=GT-I9300&pcode=HTD&os=1&type=1#firmware my AP/PDA number is the same,but the CSC number is different,is this normal?
this is apparently the stock samsung firmware for my phone PDA:I9300XXBLH3 CSC:I9300HTDBLH1 from the sammobil site, and after root mine says PDA/AP: I9300XXBLH3 CSC:I9300NEEBLH2
I would like to know if this is normal? Can i use the 4.1.1. jellybean (2012 October 4.1.1 PDA:I9300XXDLJ1 CSC:I9300HTDDLI1) on my phone using odin to flash it? Or do i have to find a firmware with exactly the same numbers as my current ones?
I am afraid i might have done something wrong,however everything works,and root checker says i have root access,and superuser is installed on the phone,if the toolkit has "updated" or changed my firmware/kernel to a uk one,does it matter?
Also,after root my phone now shows up as Galaxy Tab in utorrent,but it is still I9300 in my windows7, why is this?
Did toolkit 5.0 save my original rom/kernel/firmware before rooting? If so,where?
I would be extremely grateful for someone to easy my worrying
Thank You

Thank you for the answer. I understand everything now.. And it works fine.. I did however use the wrong firmware rom,so i got different operator,i found the correct stock firmware,and will be starting from scratch using the cf-root method with the correct stock rom.
Thank you

As I said just looking for the stock Jelly Bean firmware for my phone. I'm wanting to make it an I9300 and get updates from Samsung...I have Odin 1.85
Flash the i9300 XXELKC firmware. It's the latest official firmware from Samsung, at version 4.1.2
People say it's compatible, but I'm not sure if it would get official OTAs coming through as normal. Also changes your device name to i9300
Sent from my GT-I9300 using xda premium

[Q] Need some help Unbranded UK S3

Hi all wondering if anyone can help, by telling me wich version of 4.1.2 I can use to reflash my phone.
I am currently running 4.1.1 on an unbranded S3 that I bought from Amazon.
Details are as follows:
AP: I9300XXDLJ4
CP: I9300XXDLID
CSC: Unknown
Would I use the BTU version that is available on Sammobile?
I know how to flash using Odin, but am unsure as to which file I need with my phone being Unbranded. I prefer using Odin so I can factory reset first and start clean with an update.
Thanks in advance

[Q] I9300 Version / Flashing Fallback Version

I'am using a rooted I9000 for about 2 years and now want to switch to my new i9300. There are two thinks i hope you guys can help me with:
I'm not sure which I9300 version i got, if its sprint, verizon etc.. The phone is from germany and afaik it wasn't ordered over an telecommunication provider. That's what i can tell about the phone:
build-nr: JZO54K.I9300XXELL4
AP: I9300XXELL4
CP: I9300XXELL4
CSC: I9300DBTELL1
If everything went wrong with my i9000, i was able to do a cruel repair by flashing the official 2.3, which fixed nearly everything.
Can I do something similar with the I9300 ?
Thanks in advance

1. The International S3 GT-I9300 with a German ROM http://www.sammobile.com/firmware/?page=3&model=GT-I9300&pcode=DBT&os=1&type=1 (please search next time)
2. You can always reflash any (custom) rom by using Odin.
So if you would flash the XELL4 Rom you'll be back to a fresh stock rom.
