i am looking for dump openwrt meraki mr12
thanks all group
You question is somewhat double. What do you mean by 'dump openwrt'?
If you want to install OpenWrt on your MR12 see also the MR16 install process (see also: https://openwrt.org/toh/meraki/mr12)
thanks brother for reply
i need buckkup flash full with openwrt meraki mr12
I guess you mean the mtd backups of OpenWrt on a Meraki MR12?
Like you asked before of a NBG6616?
As I don't have a mr12 I can't deliver you them, but if you have one why not make them yourself?
Install OpenWrt -as seen on mr16 page https://openwrt.org/toh/meraki/mr16- and backup the mtd's.
If your device is (already) bricked, you need ttl-serial to get into your device.
