Never fly in the Scrapyard I guess

So I saw a few people had this problem and go it fixed but I for the life of me can't figure it out? Basically I did the first part of the train puzzle and then used fly to go heal my pokemon and train up a few new pokemon to help me fight Titania because I knew she was the next gym leader and now I can't get past the trains. People always say there's an entrance that will help you get past it but It just takes me to the area where I'm blocked off. I tried to download the patch on one of the threads but it just took me to an error screen. I've also tried going into the files to fix it myself but immediately got lost and confused. Can somebody give me some steps to fix it? Like idk what files to go to and what to change because I low key want to cry right now. Please and thank you for helping my dumb self :~:

Well, you can try renaming the last saved data to game.rxdata (do you know how to do it?) to start again the puzzle. It may be that moving a train has cut your way
