How to Fix A Bricked TP-Link Archer C7 AC1750 Router

fix your bricked TP-Link Archer C7 AC1750 router - STEP 5a

I recently got the TP-Link Archer C7 AC1750 router and wanted more functionalities on the web interface. To achieve what I wanted, I decided to upgrade the router’s firmware using DD-WRT, a Linux based Open Source firmware that works for a couple of WLAN routers and embedded systems.

After doing the firmware upgrade which was successful, I restarted the router and that was it, dead. The only LED indicator that came up was the power Indicator, the rest refused to come up. I went online for solutions, a couple of search result revealed that the router has been damaged, and advised to get a new one.

I deep searched some more and found a solution which I followed that worked after trying it several times and discovered some steps that were omitted to successfully get the router fixed.

Follow the steps below to successfully fix your bricked TP-Link Archer C7 AC1750 router.

STEP 1: Power off the router.

STEP 2: Download the latest firmware for the router from the TP-Link Website. Select your router model from the list. Home > Routers > Wi-Fi Routers.

STEP 3: Extract the firmware BIN file from the download ZIP archive. Rename the BIN file to ArcherC7v2_tp_recovery.bin and keep in a folder.

STEP 4: Download and install the latest version of the TFTP server. If it asks for firewall permissions, you should grant it for it to work.

STEP 5: Open Network settings in the Windows control panel. Change the Ethernet network adapter properties (the network adapter that is wired to your WiFi router) and set the static IP address to 192.168.0.66, subnet mask to 255.255.255.0 and default gateway to 192.168.0.1. Save the settings.

STEP 5(B): Disable the WI-FI adapter and any other adapter you have on the network connections page.

 

 

STEP 6: Disable your system firewall, Antivirus and any service that will block your network traffic.

STEP 7:  Launch the TFTP server, click the Browse button and change the Current Directory to the folder the has the ArcherC7v2_tp_recovery.bin file, Also change the server interface to 192.168.0.66 from the drop-down. Click the Show Dir tab to see the ArcherC7v2_tp_recovery.bin and then hit the close tab.

STEP 8: Connected the WLAN port on your router to your computer with the network cable. Press down the reset button of the router and power it on. Do not release the reset button for 5-6 seconds after powering it on. As soon as you release the button, TFTP server will flash the firmware and restart the router.

  1. Hi, I get a time out error when the firmware is being flashed so it does not complete transfer. THe firmware is about 15MB. Can you help?

  2. Hi Thanks for your effort. However this did not work for me. I am running Mac OSX I have a TPLink Archer C7 v5 I first flashed DD WRT and then tried to reverse that and ended up with a bricked router with only power led on. I tried this but it did not work. Could you clarify a few points please? 1- Do I Have to rename to ArcherC7v2_tp_recovery.bin even if downloaded V5 version? 2- I can not seem to get tftpServer running at all. I did all the steps several times but get error : : Service exited with abnormal code: 1
    3- What is correct sequence?:I point pathway on tftpserver enter IP/subnet/gateway as decribed, (I have router powered on at that time (I have to have it on and connected first to enter the Ip data etc on the correct IP) I run tftpserver; then I power router off and then I hold reset button down for 5 secs then power on router then keep pushing reset for 5 secs more then release. Is that correct ? Really any help would be appreciated! Thanks

    • Since you are on V5, It should be ArcherC7v5_tp_recovery.bin. I have not tried this on macOS, and I really can’t say how this would work. If you could get your hands on a Windows OS, you could try it out.

  3. this has not worked for me. I have tried with ip addressing on 192.168.0.66 and 192.168.1.66 on my tftp server.

    No log ever flashes up.

    my tp-link AC1750 is a C7v4. It powers on – flashes all LED’s – and then within moments – everything goes dark. HELP!!!

  4. Make sure to rename your BIN file accordingly as ArcherC7v4_tp_recovery.bin. And if you follow all the steps, this should work. You could also try STEP 8 more than once to get it to flash.

    I tried mine like 3 – 4 times before it was flashed.

  5. I’ve been trying to flash this for an hour. Followed all directions. Archer c5 recovery file on desktop in folder named c7, addresses all set up, but when I flash, tftp says it’s loaded, lights flash for reset, then goes back to solid on light only.

  6. Hello,

    Like several other people who have already posted here, I too am having trouble reflashing my Archer C7 v5 firmware.

    I have followed all of the instructions and have reread them several times.

    Nothing happens at all when I connect to the WLAN port on my router. I have tried this 3-4 times but no luck at all. There are zero log entries in TFTPD32.

    When I connect my PC to one of the yellow LAN ports on the Archer C7 router, I do get an entry in the TFTPD32 log viewer. It says “connection received from 192.168.0.x. Read request for file mode ocet
    File : error 2 in system call CreateFile The system cannot find the file specified.

    I’m trying to flash my router with Windows 7 OS

    It appears that the TFTPD32 software is working properly and can communicate with the router via the LAN ports, but not on the WLAN port

    Also, I’ve noticed that when I release the reset button on the router to begin the flash, the SERVER INTERFACES field in the Tftpd32 software immediately changes from the static IP of 192.168.0.66 to 127.0.0.1 (software loop)

    Please help. What am I doing wrong?

    • Don, I think i know what happened .When you re-naming the file, you should not included “.bin” , because the filename extension is .bin already and windows hide the file extension, you shouldn’t double it.

    • I had EXACTLY this happening to me but I gave it one last go and it WORKED!

      I ended up using the first yellow input port instead of the WLAN port. I had also received a message exactly like you had earlier. I actually did not disable any firewalls or anything of that sort, but I did use the same IPv4 settings and did disable all other network interfaces.

      My file was named correctly (without an extra .bin) and I had it in a simple folder hierarchy (D:\rec\).

      I also experienced the same weird server interfaces reverting to loopback thing. FWIW, it says that right now and it still worked, but it did have the correct server interface selected when I turned the router on.

      Here’s my final output:

      Connection received from 192.168.0.86 on port 2492 [26/06 16:06:04.129]
      Read request for file . Mode octet [26/06 16:06:04.130]
      OACK: [26/06 16:06:04.131]
      Using local port 63188 [26/06 16:06:04.131]
      : sent 32002 blks, 16384512 bytes in 7 s. 0 blk resent [26/06 16:06:11.770]

      Good luck!
