Model: RE705X  
Hardware Version: V1
Firmware Version:

I have multiple tp-link wifi extenders at home. This RE705X is the best of them.

I have upgraded my 5G router recently (tp-link) and I had to reset all the extenders to use the new wifi. Each extender showed an firmware-update message so I updated all of them without any interruption from my side. All went good, except for this RE705X which went into an infinite reboot loop (reset button didn't help).

 

I contacted support via email and we went through multiple steps of troubleshooting that ended by this email: issue confirmed kindly contact seller and claim your warranty 
 

The seller, after few days, replied that the device is out of warranty.

 

Feeling unsatisfied as the update wasn't supposed to brick the device and it wasn't my fault, I kept chatting with AI which convinced me that we can fix it. I ended up wiring the device through UART hoping to flash the firmware from U-boot. I was able to load the firmware I downloaded from this page https://www.tp-link.com/uk/support/download/re705x/v1/#Firmware to the RAM. However, just before flashing the AI warned me this firmware is supposed to be loaded only from the web interface and only, and we must use another binary file to be used specifically through UART.

 

So  my question is how to obtain this firmware binary?

  @ALD0 It seems your device is indeed bricked. It is not recommended to restore firmware using unconventional methods. We recommend you contact your local support for further assistance.

Hello @ALD0 ,

 

I don't quite understand what you mean by firmware binary file. Could you provide a screenshot of the relevant information?

 

You can manually update the firmware using the web interface (if your current firmware version allows it):
1. Download the desired firmware version from the official TP-Link website: https://www.tp-link.com/support/download/
2. Extract the downloaded zip file by right-clicking it and selecting "Extract All" to get the .bin file
3. Connect your computer to the extender via Wi-Fi or Ethernet
4. Open a web browser, visit tplinkrepeater.net, and log in
5. Navigate to Settings > System Tools > Firmware Upgrade > Local Upgrade
6. Click Browse to locate the .bin file, then click "Upgrade"
7. Wait for the process to finish without interrupting the extender

@Joseph-TP thank you very much for replying. 

 

This is exactly the problem. The device went through endless reboot loop after applying the update.

Now only power light is on. No web interface, No direct access through IP address.

 

from U-Boot log I can see this error:
[    2.540595] ubi0 error: ubi_read_volume_table: the layout volume was not foun                                                          d
[    2.543343] ubi0 error: ubi_attach_mtd_dev: failed to attach mtd11, error -22
[    2.550455] UBI error: cannot attach mtd11

 

so, I am trying to flash the .bin file directly to device using U-Boot CLI which is not successful yet. My understanding this binary file is ment to be used through the web interface only and there's a recovery.bin to be used in my case (using UART / U-Boot)

Maybe some tools used for OpenWRT can help. I saw in some of the device pages that some tool is used on the firmware files to prepare them. Just search up some tp link repeater/router device pages, even if not your particular model. Some of them might contain useful information.

  @Tinkerguy07 thank you for the reply. I could not find firmware for my specific device (RE705X) from this link https://openwrt.org/toh/start
The good news as per ChatGPT: "Your device is soft brick (usually recoverable)" 

“not recommended to restore firmware using unconventional methods”

Manufacturers say this because support staff usually aren't trained for low-level recovery

 

So I still have hope and will keep trying.

No, don't look for an OpenWRT firmware, just read through the pages of different tp link devices to find the tool to prepare your firmware file for uploading.

 

I think I found it. Look at RE305 page section back to oem firmware...
