Model: ER605 (TL-R605)  
Hardware Version: V1
Firmware Version: 1.1.1 -> 1.2.0

Hi All,

 

Everything was working well, and I decided to do a firmware update from 1.1.1 -> 1.2.0 on my ER605 V1.  It finished and after the restart it said the firmware update has failed.  Looking at the router the system light is off.  I let it sit for a couple hours no change.  

 

I think it might be bricked as the reset doesn't work either and the system light doesn't turn on.

 

I purchased this in July 2021 from Amazon in the US, and their support isn't open today.  I will call Monday AM to discuss the options I have now.

 

Anyone have any ideas on how to unbrick?

I had the same experience just now. No system light. But I could get a throughput to a directly attached pc to and from the modem, but it was like there was no router in between. Fortunaly I have a backup router, until this problem can be resolved. I will follow this thread.

Hi again. I got it working again by connecting directly and uploading firmware by using this guide: https://community.tp-link.com/en/business/forum/topic/263906. Now it works with the newest version firmware.

It does seem a bit odd, I had no problems when I upgraded before, you could wait a few days and try again.

And you need to make sure there was no power failure or disconnection or anything like that during the upgrade.

 

And actually you can keep this article in case you upgrade failed next time:
