Hello everyone,
Sorry for bumping this old thread, but since I managed to soft-brick my QSW-1105-5T, this may be of some warning to other users.
I was messing around with VLANs but had to finish as I was about to leave my apartment. What I did was I set all 6 ports to VLAN 1 untagged, saved my configuration and next time I booted my switch it's stuck shortly after plugging the power. If I boot the switch with ethernet cable plugged in, respective LED remains lit even after I unplug the cable and if I boot without ethernet cable, plugging it doesn't bring LED up.
I connected to switch with serial connection using CH341A adapter and Putty software on Windows machine, but switch doesn't seem to accept any input - it's just like switch RX pin would be disconnected. As a result, I cannot interrupt autoboot procedure when Press any key to interrupt Auto Boot appears. Below is complete boot log:

switch becomes stuck immediately after last line and stop ip/arp traffic ! never appears.
Even if I somehow manage to enter BCMCLI, I am unsure if there is a command to bring default configuration back as I am unfamiliar with this type of CLI.
Any form of help would be appreciated. If someone has an idea how to set switch back to default configuration, that should help me.
