Upgrade Warning There is a bug affecting all stable release 'sysupgrade' images for versions 19.07.0 - 19.07.3 that causes a boot-loop failure. Once in this state, tftp recovery is necessary to restore normal functionality. To avoid this issue, the standard sysupgrade images are not recommended for upgrading to the aforementioned OpenWrt versions. Instead, use the tftp recovery process directly (using the 'factory' image). See https://forum.openwrt.org/t/tl-wr902ac-v1-failed-sysupgrades-for-all-19-07-stable-releases/ for more details. Recovery This device contains tftp recovery mode inside U-Boot. You can use it to flash LEDE (use “factory” image) or vendor firmware. Configure PC with static IP 192.168.0.66/24, gateway 192.168.0.1 and an TFTP server to listen on that interface. Rename openwrt-ar71xx-generic-tl-wr902ac-v1-squashfs-factory.bin to wr902acv1_un_tp_recovery.bin and place it in tftp server dir. Connect PC with LAN port, press the reset button, power up the router and keep button pressed until WPS LED lights up. Router will download file from server, write it to flash and reboot. If the TFTP server shows no activity from the router, an Ethernet Switch may help, particularly if you're using Windows. Connect both the computer and the router to the switch (rather the directly to each other) and retry. Serial Root access over serial line in vendor firmware: root/sohoadmin.
