@flohack That would be great, thanks!

@lakotaubp I know, but I couldn't figure out if the specific model was the right one so tried it anyway. Thanks!

@radius3 how did you do it. I've tried several times with no results.
Also the s3 neo I got is the I9300I variant. Does this make any difference?

Hi,
I got my hands on a s3 and I'm trying to install UT through the installer.
My first problem is this point during the installation:
"Unplug and Replug
Wait until the phone has rebooted and shows a small red text. Unplug and replug once the USB cable"

The phone restarts but it stays at the samsung galaxy SIII neo logo and there is no small red text no matter how long I wait.
If I unplug/plug and continue the installation seems to proceed and finishes. After that a red dot flashes at the screen for a while, then the phone reboots and stays at the boot screen (the one with the samsung galaxy SIII neo logo) indefinitely.
The only thing I want to point is that I think I didn't check the oem unlock bootloader option before the installation. Any Ideas as to how to proceed?
