I am not a programmer but I found on the OpenWRT forum about Brick TP-link RE305 v1 with new OpenWRT

"You now have a working RE305V1 with the ability to save settings.
Bottom line: The more recent versions of openwrt do NOT work on the RE305V1. If you go back to earlier versions, you can recover your device.
On the Linux box, download the very old version of openwrt: https://downloads.openwrt.org/releases/21.02.6/targets/ramips/mt76x8/openwrt-21.02.6-ramips-mt76x8-tplink_re305-v1-squashfs-sysupgrade.bin "
