Question [Q] GT-i9300 turned into SGH-i747. How to turn it back?

Hello everybody!

My phone which is a Galaxy S3 GT-i9300 version (thats what it says on the sticker and the box) now appears as SGH-i747 (in Download Mode) product name.

I've been surfing the internet and doing a lot of research on whats going on with my GT-i9300 since I cant boot to the OS or Recovery, I can only boot to Download Mode. This happened after trying CF-ROOT (I used the one that was supposed for to work for my phone) and since then I can't install anything-i9300 'cause Odin just wont be able to because the phone displays the message "unsupported dev_type".

I thought about just flashing a SGH-i747 stock rom but I don't wanna risk my phone much more and hard-brick it

I really need help on this. Is there any way to return it to i9300?

Pleeease help me

You can try this >> http://forum.xda-developers.com/show...35&postcount=6 << (if you can get Odin to recognize your phone) but unfortunately your phone as been flashed with wrong firmware that is why it is showing SGH-i747 in download mode do not even attempt to flash SGH-i747 firmware this is not for your device and is probably the reason you are in the position you are..

(1) First rule of flashing roms BACK UP YOU EFS!!
(2) 2nd Rule of flashing roms SEE 1ST RULE!!

(3) EFS Issue look here >> http://forum.xda-developers.com/gala...uding-t2393289
(4) Rescue Firmware look here >> http://forum.xda-developers.com/show...35&postcount=6

^ I will try!

EDIT:

I tried the solution above and didnt work, I flashed a SGH-I747 rom since is the only thing the phone wants to eat. It flashed flawless. I dont know whats going on... For example, if I go to recovery mode there is an error messages about multiple CSC, but the phone is working nevertheless :s I really wish I could go back to i9300
