Hi, I've got a Samsung Galaxy S2 and I've got this problem where it freezes upon reaching the "4G" logo on startup. I looked online for answers and someone recommended to "Odin a stock ROM from your PC", and then they posted a link to this site. Now, I have no idea how to Odin, or what a stock ROM is, so could anyone help me out?
Welcome to XDA.
Please go to your device's forum using the search your device box from site. type samsung galaxy s2 and choose your device from the options. Look for the stock odin firmwares thread there. Download the one from your region, see the instructions given on flashing there. If you don't understand the instructions, check out youtube videos for that.
Odin is a easy process and just needs instructions to be followed correctly.

And inform us here when you recover your phone again.
