@asd255 i know its been a while since you posted this, but i joined the site just to thank you...my 1770nex was freezing and rebooting nonstop...only once a white screen....when i pulled the unit apart, the chip didnt even look soldered, i flowed it, but also tapped it with the iron so i could actually see some solder...so far hasnt frozen once....so thanks very much!!!
