LinkStation LS-WXL problem

[Baranek]

I have a Buffalo LinkStation LS-WXL, replaced the hard drives to 2TB and then starts problems. The machine starts up and flashes 6 times red light. Of course, I found several posts what to do in that situation, I manage to introduce the device in EM mode. Unfortunately LSUpdater not see the device - "LinkStation That needs updating was not found" (NavNawigator 2 course at that time is disabled). I downloaded the firmware to this version of the hardware, I tried the version 1.6, 1.54 to no avail. I tested on another computer with another operating system to no avail. Buffalo device is visible on the network, the computer is in the same subnet, so it should work: (Firewall and antivirus disabled).I can't forcing the firmware becouse the linkstation is not detected by LSUpdater at all. NasNavigator 2 detect linkstation as "Host name - UNINSPECT-EM124" and i think this is the main problem. :( I'm using a TFTP Boot Recovery LS-WXL 1.33. Any ideas ?
