Archer C20 V5 - Bricked after installed snapshot

[CyB3R]

Hi
I just bought an Archer C20 V5 (ES) but not really sure if it is V5, or in my country is... in the wikidev shows V4 has 2 coaxials and 1 ufl connector... and V4 doesnt have the UFL connector... mine does.. so...

I installed the snapshot available for V5 and after reboot the router stay with all LEDs on.

So i plugged in the serial console to see whats going on.. and it was saying that unable to load the filesystem or something similar, so i try to revert using the official TP-Link Firmware via TFTP and renaming the file to tp_recovery.bin

After it uploads, erases flash and install. i get this..

Porting Firmware to TP-Link Archer C20 v5

This is amazing, thanks! Last question if you don't mind, I know that origin master can already produce a sysupgrade snapshot version because Linaro's awesome work, and then the head commit of the release tag changes the build mode from snapshot to release. I've read about the U-Boot problem which you wrote down, but that's only for building factory and tftp versions. What's stopping us (or OpenWRT) to just generate the stable sysupgrade version automatically for each release? We can generate t…

You are welcome

I'm glad that your router got back and now alive

Which version did you flash your router?!!!

19.07.4 or 19.07.3 ?!

I suggest you to flash ver 19.07.3 instead, ver 19.07.4 that Linaro uploaded takes more space of flash chip

It works fine and flawlessly for me

it's your router and definitely your call

Have a good weekend
