Almost replaced the shell on my brand new deck... got caught out by the display - Divisions by zero

Title pretty much, my brand new deck arrived today and I wasted no time loading up all my games and linux desktop apps onto it. I was pretty much firmly sold on it after having the opportunity to experience one 😁 Out of excitement I also impulse ordered a full replacement shell in advance, thinking I was prepared to also tackle the screen. Turns out I was wrong - the screen is so well stuck down that I couldn’t get it to budge with a 2kw hot air gun. The battery was also getting quite warm from the heat. Pretty much ended up putting everything back to the original casing before I damaged something, and settled for just changing the back cover instead 😢 Maybe I’ll give the replacement shell another shot in future, but not too sure to be honest. Anyone managed to do a full shell swap? How did you find it?
