I asked people around how can I update specific fw. Most of them suggest me to buy cartridge that comes with FW version that I want and update it. However, buying a card only for updating is not worth and one of my friends has his own Sky flashcart that I can borrow him. I've read that we cannot update FW buy using gateway, it will be 100% bricked because there are two operation system running in the same time. (sys and emu) So, it won't work on Gateway. On the other hand, there is only one system running while using Sky. I think it should ,theoretically, work on Sky. I'm here to ask anyone ever tried to update fw by using Sky before? Does it works? PS. I'm on fw 4.5, the original one. I know that I can update by using CFW but it's too complicated for me. So, I'll take it if I don't have the other choice.
