All the above.
What you're asking still works exactly as it did before. I would say I could post a video on this but it's pointless because every single step is exactly the same. You can effectively IAP pointer hack to buy gold and other real-money items and packs. I would write this in stone.
Just check what you are doing wrong and try to comprehend what's happening, don't just mimic the procedures.
Currency changing to US dollars when you're outside the US: there's a proxy going on in the background that is making the game trace you from a region you're not in. Be careful to revert and clear all proxies you use for torrenting and safe browsing, or most likely Lucky Patcher did it for you with its IAP crack. It does not work, so in LP go to LDOE > tools > clear odex with changes. Reboot your phone.
Free crafting: there are many approaches to achieve the outcome you desire, maybe different from what you're used to in modded apks. Just browse this thread. You have guides to help you get ANY ITEM for whichever amount you decide to edit.
