Maybe this is not an option for you and you prefer turning it off if you want to protect yourself against nation state attackers. I assume the DFU mode ROM is hardcoded and therefore more difficult to attack, but if you have heard of DFU mode attacks/simulations/circumventions, by all means let us know. Turning a device off can be easy simulated on a jailbroken device as Snowden argued by asking journalist to put their devices in the fridge.
I wasn't aware that an iDevice comes out of DFU mode after some time, please enlighten us. According to the instructions [0] I understand you need a special set of actions to return to the normal firmware.
- willstrafach 10y agoI am curious where your thoughts on DFU come from. I am very familiar with it as it was the bootrom-level recovery mode my team utilized when we worked on jailbreak tools that exploited SecureROM. DFU has a single purpose: wait for an Apple-signed firmware file to be sent to it over USB for it to execute. You seem to indicate that it's something you would carry your phone around in...in which it would just reboot into iOS after awhile. Asking the obvious: Have you booted an iOS device into DFU mode before? Maybe the iPhone Wiki made it sound like it is a "mode" you can boot iOS into? I am not sure exactly what you think it is, but again, the device screen is completely black and indistinguishable from being off, OS is not booted and nothing is happening at all, besides the fact that (again) it is indeed on and "spinning" as it waits for the USB interrupt.
