Всем привет.
Есть наушники Bose QC 35 (второе поколение).
При попытке даунгрейда с прошивки 2.5.1 до 2.0.1 получил кирпич, на все кнопки реакции нет.
В инете нет ни одного упоминания, как смогли решить эту проблему, но она вроде как довольно редкая, генерируется такими же любопытными.
В наушниках слышно тиканье, при соединении с ПК постоянно происходит отключение/подключение, вероятно они ушли в вечный ребут.
Серийный номер заканчивается на АЕ.

Не знаю что делать, возможно есть смысл отключить батарею, чтобы прервать этот бесконечный цикл, по логам видно что устройство вероятно находится в bootmode.
Если знаете кто может помочь, напишите пожалуйста.
Вероятно единственный вариант - перекинуть плату с донора, т.к. наушники в идеальном состоянии.
