TL-SG105MPE switch not manageable after firmware update
I bought this switch last week and initially everything worked as expected. But because there has been a recent firmware update that included a security fix, I had to install it.
I made sure I selected the correct hardware version and the correct model. The file for the firmware update is called: SG105MPE(UN) 1.0_1.0.0 Build 20230713 Rel.40080_up.bin
After the upload finished, the firmware update began. During that whole time, nothing else was connected to the switch and nothing has been done in parallel. At some point the page showed that it lost connection to the switch. I left it like this for another like 20 minutes.
Since then nothing changed. The switch does not receive its own IP adderess anymore (inspecting via modem). I am still able to connect devices to it and they work fine, also POE works fine, but I lost the ability to manage the switch, it behaves like a hub/unmanaged switch now. A reset also did not help.
Is there any way to restore the switch?
I tried this solution: https://community.tp-link.com/en/business/forum/topic/77562?replyId=511980, but unfortunately I can not get past the login page to access the firmware update. Its really a bad experience when you just bought the device, follow the firmware upgrade recommendation and then brick it right away :/
