If you follow jailbreak news, you've probably already heard about the new checkm8 bootrom exploit.
Since this is a bootrom exploit, it cannot be fixed using a system update, and it works on all A5-A11 devices, including the iPhone X.
Hacker and Yalu jailbreak tool developerLuca Todesco is one of them. He posted several photos demonstrating the fact that he was able to change the boot logo using the checkm8 exploit:


There is no point in arguing that such a logo looks interesting.
At least to a full jailbreak tool withinstalling tweaks and Cydia is also far away, this is another proof of the usefulness of the checkm8 exploit. It is interesting to observe what developers are using with this exploit.
Let's see what else with his help will be possible to do in the future. I wonder who was the first to use it for a public jailbreak tool?
