Hi! OK i'm in serious trouble. I inadvertently flashed the wrong openwrt firmware on my Tp-Link Archer C7 V5 and now it doesn't work. I tried using tftpd64 to restore it to the original software but now tftpd64 keeps telling me:

Blockquote Connection received from 192.168.0.86 on port 3688 [05/03 15:20:10.091]
Read request for file <ArcherC7v5_tp_recovery.bin>. Mode octet [05/03 15:20:10.091]
File <ArcherC7v5_tp_recovery.bin> : error 2 in system call CreateFile The system cannot find the file specified. [05/03 15:20:10.107]

PLEASE tell me this is fixable!!

How are you providing this file?

You have to serve OEM bin as that filename
Errno 2 means file not found.

Please bare with me guys i'm totally new tot his. Ok so i downloaded the tp-link archer c7 v5 firmware and renamed it to ArcherC7v5_tp_recovery.bin. Then i used the tftpd64 by jounin to upload it. I changed the ip v4 setttings to 192.168.0.66 in the network properties and i pressed the reset button followed by the power button for 5 seconds.

Hi... Check the configuration at the tftp program.
Maybe you leave the file in a wrong directory.. as Brada4 wrote.

Can you share the config of tftp32/64?
Current directory? c:/temp?
You create this directory at your c: ?
Do you leave the file .bin there?
The tcp/ip address of your computer?
You disable the firewall of your computer, just for this tftp transfer?

Ok. the config file is tftpd32 and it's empty. There is no tftpd64 config file. The folder is located in C:\Program Files\Tftpd64. I'm connected directly to the router, and i set the IPV4 settings to 192.168.0.66 and the subnet to 255.255.255.0.

Did you place the file in the folder listed in your program?

Oh dear; you have to unzip the file and serve the bin file found inside.

HI guys. Brada4 I unzipped the archive so i have a file called c7v5-up-ver1-1-4-P1[20211022-rel59103]_2021-10-22_16.38.32.bin which I've renamed to ArcherC7v5_tp_recovery.bin. When i press the power button reset button for 4 or 5 seconds. I get the power light and what i think is the wps light.

Under server interfaces i have these:

Blockquote ::1, 127.0.0.1, 169.254.38.218, 192.168.0,66 and fe80::c3c:bbaa:41e4:26da%3.

OK I tried placing the bin file in the C:\temp folder. It began to flash but it timed out with this error:

Blockquote Connection received from 192.168.0.86 on port 3334 [06/03 09:44:47.282]

Disable all other connections - shut off laptop wifi, disconnect router wan, connect with cable directly.

Woohoo! I got it sorted! I uninstalled the version of Tftpd64 i had installed, then re-downloaded teh Tp-link bin file. After that i downloaded the newest version of tftpd from https://bitbucket.org/phjounin/tftpd64/downloads/ Finally i copied the recovery.bin file to C:\Temp. Ran the app and I'm finally up and running!

Thanks for all the help guys.
