Updating the firmware via the player's network connection took about 30 minutes with a 20down/1.5up cable connection. The files above took less than a few seconds.
The whole operation took 4 steps: 1-announcement of the update, 2-download (about 30 minutes), 3-verify (less than 30 seconds) and 4-processing (about 1-2 minutes). When finished the player turned off automatically. During the procedure, the front display showed "NET-UP".
I'll be trying multi-branching discs as soon as I can. Titles will include: T2 Skynet Edition, AVP Requiem and 12 Rounds (titles I had audio/video glitches with).
P.S. After the update, 24F was turned off. I simply turned it back on again. All other settings seem to have remained the same.
