| | Unable to upgrade 8700c to 4.5

After repeated attempts using various official versions from A220.127.116.11 to the latest A18.104.22.168 from PCCW (I need Asian language support) I have not been able to upgrade to 4.5. The symptom is the same, it stuck at the step of re-connecting to the device just before restoring, with a black display with blinking red signal light. After the timeout period it displays some such thing as needing a password. I remember this was reported early by a few posters when 4.5 first came out. Blindly entering the password or pulling battery to reset doesn't help, it's as though the display wasn't turned on for some reason.
I tried many different things including device wipe using Jl_cmdr but with the same results. I am always able to recover by reloading 4.2.1 however.
it's a good thing that 8700c is my secondary phone. My primary with BES is a 8820 and I am staying with 4.2.2 on it for now.
