I'm even going to go a step further, because this garbage triggers me.
NOBODY is going to go knock on your door and wake you up out of bed, make you breakfast, and tell you while you are eating that some new firmware or exploit is out. We aren't your mom. We don't change your diaper. We make stuff, we put it up as news. IF YOU FAIL TO LOOK, you FAILED. PERIOD. It's NOBODY'S fault but YOURS. if YOU didn't do the work, or put in the effort to create it, you are stuck.
It's garbage like that "not my fault i didn't keep up" that really aggravate me, because you literally make yourself out to be a liar. Yes, it is your fault. It can't be anyone else's. They have no access to your console, your body, your eyes, or your intelligence. I really don't want to bring bad parenting into this, due to a lack of ownership of faults. So i'll stop there.
Your console state, is your fault. It's your problem. My console works fine regardless of what you do to yours, and vice versa. We are on here to help people that need and deserve the help. Not someone that thinks they deserve it and demands. Nobody was just handed anything.
People that have been here for a while WROTE those guides you follow, or contributed to the software you use. Or they've spent hours on forums reading to help their own situation become just a little better. That's the reason they know so much about this stuff. Nobody gets paid to help you, and it's nobody's job to. It's something people do out of the kindness of their hearts.
That being said, injection method still works for 4.84. Albeit slow, and severely limited compared to CFW or HAN, it is the only current working solution you have at this given time, due to your lack of researching prior to updating. That 5 minutes could have totally given you CFW, but you chose not to take that time, and this is what you have.
