[AC Question]

OK, so whenever I try to access the page saying "Warning, Custom OS", it only turns on the phone. I turn off the phone completely, then I press the home, volume, and power button simultaneously, and all it does is turn on my phone. It used to work before, I'm not sure why it doesn't work now.

P.S., if you don't know what screen I mean, it's the one that has green text and a caution sign at the bottom. It also says click the top volume button to continue, and click the bottom volume button to reboot/restart your phone.
