Unlocking the HONOR 9 Bootloader — an informative story

I bought a HONOR 9 because I wanted a phone I could truly own. Stock firmware felt limiting: vendor apps I never asked for, delayed security updates, and no way to tinker. Unlocking the bootloader promised freedom—custom ROMs, backups, deeper control—but I quickly learned it was a path that needed care.

How I prepared the HONOR 9

I enabled Developer options (Settings → About phone → tap Build number 7 times).
Inside Developer options I turned on USB debugging and OEM unlocking. On some devices OEM unlocking isn’t visible until the phone checks with the vendor servers; if it wasn’t present I waited a day with a working network connection and checked again.
I connected the phone to my PC, ran adb devices to confirm the connection, and allowed the PC when the phone prompted me.
