Зачем нужен разблокированный бутлоадер (загрузчик):
Заводская прошивка будет работать и с заблокированным и с разблокированным.
Кастомная/своя/мод прошивка не запустится на аппарате с заблокированным бутлоадером.

Если прошить устройство не-заводской прошивкой и не разблокировать загрузчик, то вместо запуска будет чёрный экран и текст, что устройство неисправно.
Что делать:
1.Разблокировать загрузчик или 2. Прошить заводскую прошивку

Если загрузчик разблокирован, то при запуске устройство напишет примерно такой текст
Your device has been unlocked end cant be trusted.
Your device will boot in 5 seconds.
и потом запустится как обычно.

Code: Select all

Your device is corrupt.
It can't be trusted and may not work properly!
If you see this message it may be damaged firmware or HARDWARE fault, f.e. dead flash chip.

How to fix:
1. Flash device with factory signed firmware
OR
2. Unlock bootloader
