I wanted to update my firmware since my phone has been giving me problems lately. The phone is a rooted Samsung Galaxy S3 (SCH‑I535) with the standard rom. I tried to flash it back using ODIN with the guide from this youtube vid but it keeps hanging at the Verizon logo screen. Not sure if it's an issue but I didn't reset my flashcounter to 0 before trying to go back to stock. I can still get into recovery and use ODIN so what should I do? Should I just root again and reset the counter before I try to go back to stock or is there another way?

Edit: S3.....

I am going to order my first helmet today and have narrowed it down to either the Scorpion EXO-700 or HJC C-16 since both have Snell and DOT ratings and are afforable. The helmet I really want is the Shoei Multitec but I just got a crazy car bill for inspection so I will be low on funds for a little while. I have a kind of big head so a more round and large helmet would work best for me. I always wear glasses which is why I liked the flip-up helmet option but I can manage with whatever.
