i need a little help. Yesterday i received my brand new RB951G-2HnD device. After connecting it to my PC i used WinBox to configure the device. On the QuickSet panel i checked for a new version of RouterOS and it offered to upgrade from 5.22 to the new version 5.23. I started the upgrade process. It downloaded the packages correctly, and said "rebooting". The router is no longer accessible from that point.
Symptoms: after powering on all LEDs are blinking one time, there is a single short beep, and the ACT LED blinks one more time. If i connect an ethernet cable to any of the ethernet port the LED assigned to that port starts to lit continuously, but the machine i connected says "No network connection". Unable to connect with WinBox or to WebFig. Tried the reset button, nothing changed.
Also tried the NetInstall procedure to reinstall but i could not make the device boot from the NetInstall PXE server, at least nothing is showing up in the list of the NetInstall app (except the HDDs of my PC).
Have i bricked my new 0day device? Please hint me how to bring it back to life, if possible. Thanks in advance.
