It always looks easy on YouTube - even the videos that say "this is the first time I ever did this" - but most of those people are really cellphone repair people, and have done it dozens of times already (and destroyed a few phones the first few times, which is why repair shops keep unfixable phones - for new people to destroy while they're learning). How do I know that some of the videos are fake? I recognized one person claiming to be doing it the first time - and he'd been repairing phones for about 4 years when he made the video.
But I never heard of chilling the glue - that does seem to be a method you can use successfully the first time. The normal problem is overheating the screen when you use a heat gun to remove the glass, but dry ice can't get colder than -78.5° C, and if that removes the glass ... why didn't someone figure that out when I still owned my stores?
It can't hurt - try removing the glass. (Use thick gloves - not only because the dry ice can kill skin, but because some tiny shards of that cracked glass can do a lot of damage to your fingers.) If it comes off clean, buy the replacement and you're good to go. If the dry ice doesn't do anything you've wasted what - a dollar? It may take time - freeze one shard, remove it, freeze the next piece, remove it. Etc. But knowing how to replace the glass on a cellphone screen is a valuable talent, so do it just for the knowledge (and who knows - you might make good money by doing it for people in your town). If you get $200 more on the trade-in for half an hour of work - I'll take that any 40 hours a week.
