Mate your messages are outright aggressive & these people are trying to help, Im not sure how you cant see that.Your message is passive-aggressive.
Again you dont want to risk a banned switch, but most sites like ebay/amazon are backed & refundable & your paying around 200usd just for the modchip anyway. You can probably find an unpatched tablet for that & can message the seller.
Given the fact that you think a modchip is a simple as connecting a few wires, I would strongly not consider you even try replacing the backplate on your switch.
Either grab an unpatched tablet online or find the hwfly or some other clone on ali express those are your options. If you go for the later definately hire a proffessional.
But if you come here & give people attitude because you dont like the help your given, apart from people thinking your an a-hole, if you need help in future nothing will come your way.
