Ищу дамп Archer A7 V5

Здравствуйте.

Думал на официальных форумах такого не просят, но поискав по форуму по слову "Дамп", увидел что и тут такое возможно. Попробую и я.

По собственному незнанию, убил новый роутер. Пробовал скачивать *_recovery.bin и зашивать программатором, но роутер почему-то всё-равно не грузится. 2 светодиода горят в полную силу, а остальные чуть-чуть. Хотя судя по binwalk-у, в этом файле есть и U-Boot и ядро.
Есть дамп флеша уже после момента когда запорол роутер, где U-Boot ещё живой и через TFTP пытается качать *_recovery.bin. Но по какой-то причине, после того как роутер скачал bin файл (завершение скачивания видно по tcpdump-у), моргает 1 раз индикатором питания и больше ничего не происходит.
Пробовал подключатся к UART на таких настройках: 115200, 8N1, так же пробовал заменить скорость на 9600, но в порту пустота, не одного сообщения, даже мусора нет.

По этой причине ищу дамп флеша для Archer A7 V5.

Спасибо!

Дамп нашёл. Дамп был снят с заведомо рабочего роутера. Специально купил второй роутер чтобы снять с него дамп.
Но после заливки его в флешку, роутер не грузится. Даже U-Boot не грузится. Просто горят 2 индикатора: индикатор интернета (желтым) и 2 лан порт.
Подозреваю что нужно что-то изменить в дампе, но не совсем понимаю что.
