I'm running PS3 v1.50 firmware with PS3.ProxyServer.GUI and the firmware by-pass is working 100%. I've even been able to get on-line and play Resistance Fall of Man.
Using PS3 Proxy, re-direct the following Sony link to your local ps3-updatelist.txt file
Code:
fus01.ps3.update.playstation.net/update/ps3/list/us/ps3-updatelist.txt
This is the contents of my ps3-updatelist.txt
