Updating a HP(E) server from iLO 3 version 1.55 to version 1.94

This short document explain how to resolve the issues arising when trying to update an old (Gen7) HP(E) server to the most recent iLO 3 (HPE Integrated Lights-Out) version, which solves a great number of security and usability issues.

Issues

Can't connect to iLO with a modern browser, for lack of supported TLS protocol version
- solved by using FirefoxPortable version 31
- and in the Firefox31 portable configuration, in the about:config settings, set security.tls.version.min (the minimum acceptable version of the TLS protocol) to 0 in order to be able to negociate down to TLS 1.0 (even if iLO 3 can do 1.1). Keep in mind your browser is now (even more) vulnerable to a host of attacks, do not connect to any potentially hostile host with it.
alternatively sabotage your regular Firefox securit

NONE OF THESE CLIENTS ARE VERIFIED BY ME FOR SECURITY OR ANYTHING ELSE! USE AT YOUR OWN RISK!

Update 2025-07-16: Use either Revanced, NewPipe or Firefox with add-ons. Revanced is my personal pick, due to it being a mod of the official App like Vanced, but better (e.g. it has integration of Sponsor Block, Return YouTube Disklike and more).

I wouldn't recommend Kiwi Browser anymore as it has been discontinued. AFAIK it has been accuired by Microsoft and the extension support has been merged into Edge (Canary). But you'd have to use Edge. Yuck.
