Hi,
Have just realised that the current files available for upgrade and packaged in all the OS version 3.30,5.10beta3 and 4.10 are all the same.

If u view content of the packages all are from the 4.10 release.

Could someone please clarify this ..as all my upgrades fails.
Anyone from support??

Check on there site :http://www.mikrotik.com/download.html and view content for each of the packages available for download.

regards..

I just tried it again and it is ok. I used the two dropdown lists.
Select your hardware in the upper dropdown
Select Legacy for V3.30 (or select the version you want) on the lower dropdown

Click on "Combined Package".

ADD: Do not expect replies from MikroTik tech support until Monday. They are closed for a Latvian holiday until then, according to the MikroTik home page.
