Hi! I need assistance for my bricked TL-WR831N. As it was running an old version of HW v8 firmware, so I tried to install the last release of v8, but the router stopped working after the installation. Whenever I turn it on, onlt the power light stays lit and when i turn it on while  holding the wps/reset button, the wps led stays lit for about 10 seconds with the power led and again behaves the same. I tried tftpd but it failed. I have given up, but is there any last thing to try for unbricking the router? Thanks in advance!
