Hello? I have router RB2011UiAS-RM with OS v. 6.32.2 and routeboard firmware v 3.24, i want update OS to latest version (6.43.2 (Stable)), but all the methods that I used did not lead to success, after router reboot OS version remain old 6.32.2. I tried auto-upgrade and manual (upload file - routeros-mipsbe-6.43.2.npk to file directory and reboot), but all in vane. Please help me. Thank you.
