Model: Deco BE85  
Hardware Version: V2
Firmware Version:

Hi!

I recently acquired a Deco BE85 (used, no warranty I would know of) that is displaying a constant yellow light when plugged in.

 

Thing is: I can boot it into recovery through the reset pin, connect through 192.168.0.1 through the LAN port and flash a firmware. The webfrontend says it was flashed successful, but I have my suspicions, because the first 6-7% move quite slow like its actually doing something and then it suddenly jumps to 100% and says complete. If I remeber correctly, for my other Decos the process was way slower. So I am not sure if the firmware is applied after all, or if its doing a simple check, sees its own firmware version is more recent and then rejects it or something. Point is: When I try to start the Deco normally after the flash, I am still getting the solid yellow color - no other reaction.

I am pretty sure its in a boot loop, because I can reset it into recovery from the yellow light even without disconnecting the power if I wait a bit.

This leads to a couple of questions:

 

1. Is it possible, that the recovery firmware is not flashed because there is already a more recent version installed on the device?

2. How can I do a factory reset in a boot loop situation when I cannot flash a firmware?

3. Is it possible to access a bootlog/firmware installation log through recovery somehow?

 

Thank you for your help!

 

Jens

Hi, Thank you very much for the feedback.

What are the model numbers of your other Deco units? Are they also Deco BE85?

- if yes, maybe you could swap the power adapter first.

 

 

There are some details for your reference:

2. How can I do a factory reset in a boot loop situation when I cannot flash a firmware?

For factory reset, you only need to press the reset pin only for 1s. If it stays on solid yellow, it no longer responds to the factory reset.

 

 

1. Is it possible, that the recovery firmware is not flashed because there is already a more recent version installed on the device?

Have you noticed any LED changes during the firmware uploading process?

And what is the current firmware of Deco BE85 and the flashed firmware you want to install?

Even if the Deco BE85 is on the latest firmware, you could still flash the same firmware again via firmware recovery.

 

 

3. Is it possible to access a bootlog/firmware installation log through recovery somehow?

I'm afraid there haven't been any bootlog/firmware installation log saved somewhere on the Deco APP or firmware recovery utility.

 

Best regards.

  @David-TP Hi David,

thanks for getting back to me!
The other devices are indeed also BE85 and I just tried another recovery with a different power supply - unfortunately with the same results:
 

The unit in question is a BE85(US) Ver.2.0 and I am trying to flash BE85_SP1v2_V2-up-ver1-1-1-P1[20241023-rel34667]_2024-10-23_17.58.40.bin

 

Unfortunately I have no method to check what firmware was on the device before updating it via recovery.

 

The LED does not change during the firmware update process. It stays solid green all the time. I do have a short loss of network connectivity though - when it jumps from ~9% or so to 100% and "finished successful" the device does miss a couple of pings before coming back online...

Hi, Thank you very much for the update.

In case it is just a bad LED If you connect a laptop via an Ethernet cable to this Deco BE85 with solid yellow light, can you receive internet access through the Ethernet cable connection?

From your TP-Link ID, there was a newly added Deco BE85 and its firmware is on the 1.1.1 Build 20241023 Rel. 34667. So it is on the latest firmware already whether the firmware recovery works or not.

 

Wait for your reply and best regards.
