I really don’t understand why I write nonsense. I had to use secret information channels to understand what Reboot to Bootloader is. So the first thing I learned was that Reboot to Bootloader is an item in the menu. One person says that in short he was sleeping, and at that time the phone rebooted itself and after that it no longer logs into the system. Moreover, after the reboot, Software status: Modified is written at the top of the screen, there is also an item Reboot to Bootloader, if you select it, the inscription changes to Software status: Official. There is also a Boot to Download Mode item, if you select it, then after turning on the smart phone it will be written at the top Failed error to boot download mode. In short, it’s not clear enough
If we literally translate Reboot to Bootloader, then if I’m not mistaken, the translation will be like this: they say it will reboot to load Bootloader, this is apparently boot menu, something like that.

Apparently this is when the phone is locked somehow. That is, the phone needs to be unlocked, or rather not even the phone, but the bootloader. So guys, I understand everything and what can I tell you here. I’m not such an expert to advise anything, but I can give you a link where you can probably get some important information, here’s the link:
