u/Flashy_Reach_6981

Maybe it’s a stupid question, but I bought it before I knew about the cross point flashing. Bought it from there beacause Amazon doesn’t have them in my country and from their official website the shipping was outrageously expensive.
Was it worth it? I thought I didn’t need any third party software, and everyone in the comments said they could flash theirs no problem.
What do I do now? Do I cancel my order?
Thank you for any advice
