DVR Zmodo- вопрос по сохранению прошивки.

[aavan]

Доброго всем времени суток!Ремонтировал вчера DVR Zmodo(больше никокой инфы на наклейках нет)Неисправность "железная",решилась довольно легко.Сейчас стараюсь сохранять прошивки аппаратов прошедших через мои руки,в основном программатором ,иногда и через tftp.В этом случае программатор отпал-никак не прикуплю "кроватку".Через tftp тоже облом-стоит nand,а как к ней обращаться не знаю.DVR уехал с клиентом,но на будущее хотелось бы знать как сделать бэкап прошивки в случае с nand.прилагаю help & printenv.
