Hello,

I have flashed OpenWrt on my TP-Link WA850RE and bricked it.

Now I opened the device and connected it to my pc (over serial)
Then I set up a tftp server and downloaded the new OpenWrt firmware.

I used this side for the instructins:
https://wiki.openwrt.org/doc/howto/gene … ing.serial

But there says:
DO NOT USE THESE VALUES. FIND OUT THE RIGHT ONES! NO, NOT KIDDING.

Can someone tell me the right values to flash the tp-link over tftp?

This is what I get when I use the command printenv
