TL-SG108E not managable
Just buyed the TL-SG108E and installed the 'management' utility. Switch was perfectly found.
I saw on the support pages there was a newer firmware (20181130) and I want to install it.
I have started the upgrade with that downloaded file and about half way 'Some error occured' was the message.
After that error the 'Unmanaged Pro configuration utility ' was not be able to find the switch anymore.
I want to reset the switch, but how should I do that? (I have seen the reset hole, but 'pinning this' gives no result
Thanks for thinking with me

How to hard reset it: With the switch powered on, press this button for five seconds or above to reset the software setting back to factory default setting.
Then connect the computer which installed the configuration utility to the switch only and setup static IP for the computer as the instruction below:
https://www.tp-link.com/support/faq/14/
After that, please verify whether the utility can detect the switch; if not, please ping the gateway of the switch and show us the results.
Note: The gateway is 192.168.0.1 by default.
Good day.

Hi,
I have the very same issue - received my switch today, wanted to upgrade the FW to Version TL-SG108Ev4_en_1.0.0_[20181120-rel40749]_up - the Unmanaged Pro Configuration Tool showed an error and the Tool is not showing anything anymore.
During the upgrade the SG108E (V4) was connected to an SG105E (V1). The SG105E is still showing up in the Config Tool. Lights are still on on the SG108E and even Network seems to be up.
The Gateway 192.168.0.1 could be reached (ping is showing results), but this might be influenced by the SG105E.
I tried to connect the SG108E directly to my PC and to change my subnet to 192.168.0.x - but then the switch did not show up in the Config tool as well.
The Reset Button is doing nothing btw...at least nothing, I can see. I've pressed it for far more than 5 Seconds, turned off power, pushed the button before turning power on again....all does not change the behaviour.
What else could be done to revive the Switch?
Or is it directly bricked by the standard update procedure?
Cheers

I've tried the direct connection now again - Config Tool does show nothing, Default Gateway of switch is pingeable...
What next?

Not sure it matters, but subnet mask should be 255.255.255.0

I have in the end been able to achieve a good result on a BRICKED SG108E v1.
Before you start, step 2 is probably better on a Linux machine to achive NMAP scan over the sw 192.168.0.1
- Configure network interface with an IP on the same subnet
IP = 192.168.0.10
NETMASK = 255.255.255.0
GW = 192.168.0.1
( after that, try to ping to switch ip 192.168.0.1 if you reach the host, continue to next step )
2. From linux machine, execute this command (install it if you don't have: sudo apt install nmap)
3. Once you are done, execute: sudo nmap -Pn -sS -sV 192.168.0.1
4. With the results on screen you can see something like this:

5. As you can see, there is some pages on the switch HTTP server. If you try to connect on http://192.168.0.1 you will not see anything BUT
6. You can enter on one of those pages like that
http://192.168.0.1/menu.cgi
7. Now you are able to upload the firmware by two methods, TFTP or HTTP (easy way = http)
8. When you select HTTP Firmware Upgrade, select "browse file" and choose the correct firmware.
9. You are DONE, wait a few minutes and you can loging through Easy Smart Configuration Utility again.
NOTE: Is mandatory that SW will be on "Loader Mode" you can check for example trying to access to http://192.168.0.1/login.html and see that
Hope this help to everybody to bring back to live a TP-LINK SG108E (in my case V1)
