Convert TL-WR703N back to standard openwrt?

[dac_2020]

I have a number of units which were used for mining and now I want to convert them back to openwrt.

Units are identical to new, nothing unusual hardware wize.

TP-Link TL-WR703N
hardware version 1.6 (even confirmed on the Ethernet port sticker, 1.6)

However, everything I have tried from making my own build using the latest image builder to try both factory and sysupgrade failed, to using openwrt factory and even using original tp-link software.

Each time, the upgrade bricks the device.

More info in /etc

in a file called avalon_version
20131229
cgminer: 698d677
cgminer-openwrt-packages: aadd747+
luci: 346e3e7+

Wondering if anyone might have some insight.

Thanks.

Are you sure the device is bricked, or can you still communicate via TFTP? If you have the right firmware for the device, I could only guess the issue would be from not waiting long enough for the firmware to flash before hard-booting it (I screw this part up A LOT: I'm impatient). Hard to say without being in front of it, though.

Here is my post on openwrt with LOTS of extra info

[dac_2020]

It no longer boots. One LED blink and nothing else. It doesn't look for a dhcp address nor does it set one once it goes into this mode.
I figure at this point, it's bricked. I'm saving all the bricked units and will try to serial recover them in the future.

Does anyone know what the cgminer-openwrt-packages does to the device that it cannot be returned back to a standard factory openwrt build?

[dac_2020]

How about this... does anyone know the steps needed to convert the device to a u-boot version so that I can then restore a standard openwrt image back on these devices.
