Ошибка FTMTOOL

Гайд с Хабра

Данная ошибка в большинстве случаев возникает из-за проблем с кабелем и/или преобразователем, когда osmocon не может связаться с загрузчиком. Убедитесь, что контакты GND, RxD и TxD подключены правильно, а наименование чипсета Вашего USB-TTL преобразователя содержится в списке рекомендуемых. Попробуйте повторно нажать кнопку включения через несколько секунд. Также для некоторых моделей телефонов и преобразователей значение ключа -m программы osmocon следует указывать без окончания xor, например, -m c123 вместо -m c123xor.

Вывод osmocon в случае ошибки:
