Problem flashing TL MR3020 with OpenWrt Firmware

Hello people,

I came across PIRATEBOX and its installation procedure for a TPLink TL MR3020.
The PirateBox elaborately details the procedure with all necessary links.

However iam having a problem flashing my device with the OpenWrt firmware specifically available for the MR3020
openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin 26-Dec-2014 09:31 3.8M

I stuck to the basic instructions provided to download the required files and copy them to the flash drive and subsequently flash it through the router setup page on 192.168.0.1

The firmware upgrade halts with an error " unsupported firmware" .

I confirm that my router is the TL MR3020 (hardware version indicated on the setup page: WR841N V9.0)

I would appreciate if somebody could help me out of this situation by providing an alternate download link to the appropriate firmware.

Thanks and cheers to the great work of the developers and supporters!!
