Default [Q] S3 Firmware install error/install loop

Hi guys

I have looked through a lot of threads before I decided to start this one with my issue.

my friend flashed the S3 from 4.1.2 to 4.2.2, so then I flashed it to 4.3 (BTU-I9300XXUGMK6)
It worked, but with lots of issues like some apps doesn't work, and random restarts.

So I decided to downgrade back to 4.1.2 with Odin, and guess what? I got stuck in a loop with Samsung Galaxy III screen. so i went into recovery mode to reset/factory restore setting and nothing happened.

So I tried installing another version of 4.1.2, and now I'm stuck at the installing loop, where the android has a cube thingy rotating in the stomach, then goes back to Samsung Galaxy III screen and repeat. It looks like as if the phone is trying to install the firmware, but it restarts before it happens?

Interesting thing is that I can get into download mode, but thats it.

Another thing is when I tried to flash it back to 4.3, everything in Odin was a success and when the phone starts to reboot and install...there is a green robot lying with exclamation mark and then reboots and repeats.

Any help
Thanks

Boot into recovery then factory reset, flash only 4.3 first with Odin.

If you've corrupted the efs folder during your downgrade then you'll need to restore a backup, no backup then pay for a repair.

Nobody searches. Nobody reads the first posts or titles of threads. Nobody even looks at posts a couple above their own.

Thank you! This is very helpful, much more than other threads that I've find, since not many have the same problem as I have.

I can't even reach recovery mode....so I guess the only way is to pay for a firmware repair from Samsung....

I did back up the phone data, but I guess that didn't help much.

Try the rescue firmware, search in general forum, but follow the guide exactly as it includes a pit.
