could someone give me an instruction, how to recover stock OEM firmware into TP-Link Archer C6 v2 EU?
Now Im using OpenWRT 19.07.1, but Im facing poor performance on 5GHz radio, which is the reason for rollback to stock OEM firmware.
I tried to upload stock fw over LuCI and TFTP as well, but router became soft-bricked everytime.
After that, if I upload OpenWRT image over TFTP, router starts well.
I suppose, that there is something about stripping bootloader part from stock firmware, but I really don`t know, how to tho this.
Hi there
you don't need to strip firmware because this router firmware doesn't contain uboot
just rename ArcherC6v2_eu-up-ver1-2-1-P1[20200110-rel60119] to ArcherC6v2_tp_recovery.bin
then upload it via TFTP Server
Thanks for reply. I allready did so, and also forced 100Mbps FullDuplex connection as it is specified in router techdata page. But still the same behavior: TFTP shows popup and runs succesfully to 100%. Then router restarts and hangs on power LED steady light up and all other LEDs off.
I made all the same as on video, but unfortunately still the same result: after restart router hangs on power LED steady light up and all other LEDs off
Without any problem I tested it with My Archer C60 V2
first of all, turn off your firewall then set ip to 192.168.0.66 in LAN card, then rename your firmware to tp_recovery then upload it via TFTP Server when upload is successfully done "BE PAITIENT" for at least 60 Seconds and DO NOT DO anything untill The router restarts
Use of ArcherC6v2_eu-up-ver1-2-1-P1[20200110-rel60119].bin: TFTP transfer goes well, but after restart router hangs on power LED steady light up and all other LEDs off.
Use of openwrt-19.07.1-ath79-generic-tplink_archer-c6-v2-squashfs-factory.bin: TFTP transfer goes well, and after restart router boots and works fine.
Tried both versions, but without success. So I am back on 19.07.2.
I found strange behavior: After TFTP upload of orig fw it will reboot shortly after 100% in tftp gui. However, after upload of openwrt, it will take few seconds, maybe for some processing.
I suppose, this is caused by reaching end of partiton space (maybe this assumption is wrong)
Okay, so I just made an account here just to post this.
To return to the stock firmware through tftpd, you'll have to use the very first (oldest) firmware available on the official website. All the others will show success in tftpd but won't boot. Here is the direct link https://static.tp-link.com/2020/202001/20200123/Archer%20C6(EU)_V2_020110.zip.
You can update to the latest firmware after installing this one via webupgrade.
I had big issues with 1.3.6. version of the firmware. Upgraded to open wrt and then tried downgrade to 1.2.1. as suggested in David's post. After that the router was bricked.
Next I followed the in unbrick guide with tftp that David posted, but non of the firmware resulted in a successful unbrick.
But I got it to work, you need to find firmware 1.0.1. It's not on the tp-link site anymore, but someone posted it on 4 shared. this one successfully can be applied with this method. After that you can upgrade to 1.2.1. through tp-link ui.
Here is the link that I managed to find on the net for stock 1.0.1. firmware.
Hope this saves 4 hours of stress for the ones in the same situation
Final addition. This stock firmware restore can also directly be done from 1.3.x versions of the router. Just use tftpd64 program and follow David's instructions and use the provided 1.0.1 version.
Just did this on my second archer c6 eu v2.0 without open-wrt
