Set static IP on your PC: IP 192.168.1.254/24, GW 192.168.1.1 Serve ImmortalWrt initramfs image using TFTP server. Cut off the power and re-engage, wait for TFTP recovery to complete. After ImmortalWrt has booted, perform sysupgrade. Additionally, if you want to have eMMC recovery boot feature: (Don’t worry! You will always have TFTP recovery boot feature.)

Ставим пакет cfdisk
Набираем команду SSH/Serial “cfdisk /dev/mmcblkX” (без кавычек и Х это номер раздела у опенврт и имортал могут различатся). Откроется окно программы cfdisk. Внимание, в режиме serial окно может глючить, моргать и отображаться криво. выбрать с помощью кнопок вверх-вниз строку с разделом “/dev/mmcblkXpX”. (X у разных прошивок разная)
После выбора нужно строки с помощью кнопок влево-вправо выбираем пункт меню “Resize” и нажимаем Enter.
Подтверждаем расширение раздела до максимума (программа сразу подставит весь доступный объём памяти, что-то около 7.2Гб): нажимаем Enter.
С помощью кнопок влево-вправо выбираем пункт меню “Write” - записать изменения. Подтверждаем запись, напечатав “yes” и нажав Enter.
Выходим из программы, выбрав пункт меню Quit кнопками влево-вправо.
Перезапускаем устройство.
Перешиваем sysupgrade через веб-морду Эт примерное что я делал
