Unbricking and restoring OEM firmware - Archer C7 V4

I tried to reinstall the oem firmware using the instructions at https://openwrt.org/docs/guide-user/installation/generic.uninstall:

mtd -r write /mnt/sda1/original_firmware.bin firmware

Where "original_firmware.bin" was what I've extracted from the ZIP from TP-Link's site

After flashing the bin, the Archer C7 automatically rebooted, but now it seems to be bricked

When turned on, the power led turns off after two seconds and that's it

Is there anything wrong with those instructions? Should I use a different type of image?

Any advice would be appreciated, Thanks!

What was the exact name of the extracted file (ArcherC7......bin)?

It was "Archer C7(EU)_V4_180425.bin"

I renamed it on the USB stick for ease of typing

You have to strip a factory firmware before flashing it with sysupgrade. Since you didn't do that, it's bricked.

TFTP recovery should still work.


I added a waring at https://openwrt.org/docs/guide-user/installation/generic.uninstall

Also sysupgrade is recommended over mtd write whenever possible since it is certain to write to the correct partition.

Good instructions for stripping and flashing can be found here: Help required to revert to stock TP-Link Archer C7 V4 EU
