[Q] GT-i9300 (International) 32Gb Boot problems topic

Hi all

On Thursday evening, my cellphone was drained flat as usual by the evening.
When I got home, I put it on charge. After a few minutes I tried turning it on, it got stuck at the Samsung splash screen,
wouldn't boot any further. After trying a few times, removing the battery, etc, I ended up just leaving it off but on charge
the whole night. The battery was fully charged the next morning(so it's not a battery issue). I had the same issues that
morning.

I spent the whole day on Friday, trying to fix this cellphone of mine. I tried tons of fixes I found on this forum(although
a lot of them use programs/files uploaded to a file service that has been closed down[really annoying]). Posting here
is definitely my last resort, I can't think of anything else to try...

I have tried flashing the firmware
I tried to get Kies to do a firmware update and initilisation
I tried various fixes and went through many, many forum posts.
Last thing I tried is to flash the .PIT and flash what I thought was the original firmware I eventually got hold of from sammobile
I tried the last step twice and am busy downloading another version.

What happened with this, is it'll boot, I see the android with his stomach open and something happening inside, it then reboots
and does exactly the same thing as it had previously done, gets stuck on the Samsung splash.

Could someone maybe step me through how to flash it again? I think I need to basically start from scratch, new PIT and all.
I have the GT-i9300(International) 32Gb - I bought it in South Africa

Thanks very much for any help in advance
