But I thought you said:
i got problem updating multiman. it freeze on mmcm logo.. can it be fixed? mine is multiman 2.09.00. want to update to 4.05.00
Why stick to something old that freezes?
Have you tried remove mmCM, install 04.05.00 base plus from here: http://www.sendspace.com/file/ja54y2
Remove any external USB HDD's or devices, and try boot up mmCM from XMB.
Perhaps its a HDD issue, I noticed my copy of mmCM takes a lot longer to boot when the HDD is plugged in (especially if I add new games) , but after that its fine.
You should give that a try, once mmCM is loaded (if it loads) reconnect your HDD and click refresh connected drives.
Is your external HDD formatted to FAT32?
