In this video, we will show how to exit EUB mode on devices stuck in EUB using the Repair Boot procedure.

EUB (Emergency Upload Boot) mode is a low-level diagnostic state on Samsung Exynos devices. While useful for advanced debugging, being stuck in EUB mode can prevent the device from booting normally. Using ChimeraTool, you can safely and efficiently exit EUB mode, restoring the device to a functional state without requiring extensive manual intervention.
