Hi, I recently updated the C++ depthai-core version to 2.26.0. I saw this ``` [depthai] [warning] [18443010C10149F500] [3.3] Flashed bootloader version 0.0.26, less than 0.0.28 is susceptible to bootup/restart failure. Upgrading is advised, flashing main/factory (not user) bootloader. Available: 0.0.28 ``` I have a few questions regarding the upgrade: 1. When using C++ depthai-core compiled binary. Is it possible to update the bootloader without a Internet connection? Namely is the bootloader file compiled into the binary? 2. What should be the correct line of code to call to update the bootloader. Particuarly im less sure about "`flashing main/factory (not user) bootloader`" Thanks!

Yes.
