Unfortunately I don't have a login, because I was cheated, and the brand of my products is ALu and not Aruba and they don't give me a login for direct download, it must been through the partner.
Anyway the official answer was:
"Alcatel version of 6.4.2.12 code is not yet released and it is still under testing. And all the codes which are available on the Alcatel BP website are tested and will be able to install on the production network.
The latest version on the same series was 6.4.2.10. The latest tested version for your controller is 6.4.3.3 and that I have already provided you."
Which apparently is not true...
