i have installed openwrt on td w8968v4.now i want to back oem frimware. please help me.
i had tested the firmware openwrt-brcm63xx-generic-TD-W8968-squashfs-cfe.bin on TP-Link TD-W8968 v4 and works fine.
1 - poweroff the equipament;
2 - with the reset button pressed, turn on, wait 5 seconds..
3 - browser to url 192.168.1.1 and put the firmware openwrt-brcm63xx-generic-TD-W8968-squashfs-cfe.bin
4 - after configure .. update the packages, connect via ssh and run the commands:
lookup the packages names to upgrade..
opkg upgrade <packages>
I don't understand why you're showing me that, I asked you to provide a copy of this error.
Also, I asked about flashing via sysupgrade, the Wiki page shows flashing to OpenWrt from stock using an OEM restoration GUI. If this flash method is still available and isn't working, you likely have a bigger issue unrelated to OpenWrt.
If you want assistance, please copy/paste your error!
i will tried cfe tftp method but a error came up f 192.168.1.35:op.bin
