I have a problem with my iPhone that makes it go into DFU mode if I lock it. It only goes into DFU if it's not charging, not playing music and lockscreen not lit and I have to boot it tethered from my computer. At the moment I have a tweak from Cydia installed that stops the lock screen from dimming but only if I make it lit (ie. press lock button/auto-lock -> iPhone locks and screen dims -> presses home/lock button -> lockscreen lights and stays lit -> no DFU). I'm wondering if there's a tweak where the lockscreen is still lit even when I lock (ie. presses lock button/auto-lock -> iPhone locks and screen stays lit -> no DFU mode). Thanks for the help
