Hey everybody, I use a Samsung Galaxy S2 Model No. GT-I9100 and I was wanting to go back to my Stock Rom. I bought this device second hand from eBay it came from Puerto Rico. I turned on the phone and noticed it's from this carrier in South America called Entel. This is what happend when I first recieved it, I assume this is most likely the stock rom but now I've installed other ROMS and stuff on it and want to go back.

I'm just not sure how stock roms work. Like if it is truly the stock firmware will it work without having additionally modding it and only having to flash it with Odin in the downloading mode? Will only one firmware work with flashing it like that in download mode and then it works?

 

I mean I've tested it before and it works by just flashing in download mode with Odin. So is it the true original firmware that came with the phone. I mean it looks exactly like it.

 

I mean it must be the stock firmware if all I need is

1.) go into download mode with android
2.) open odin v1.85
3.) go to the pda and select that I9100UHMS8_I9100CHEMS3_I9100UHMS1_HOME.tar.md5 file for the pda box
4.) do the start button

I mean it works and takes me to what the phone looked like originally with the entel start screen and everything
