The article states "Download the orignal firmware from TP-Link home page" --> DON'T DO THIS IT WILL HARD BRICK YOUR DEVICE.
I learned too late that you need to download a trimmed version of the firmware because if you don't it will hard brick your device and this one you don't get from tplink homepage (see the above comments for suitable firmware files).
Because with original firmware from tplink homepage it starts writing the firmware and then fails with "failed to erase block". If this happens you still have a chance as long as you're still connected through ssh. Download correct trimmed firmware and flash again and you're good. If you reboot or loose ssh connection you're fucked and you can throw device in recycle bin unless you want to break open the case and flush with a serial console cable but given the value of device and the hassle it would be I just recycled it.

Don't ever use file from TP Link Home Page , instead use file from this website https://www.ofmodemsandmen.com/factory.html
