Can you give me the original 4.50 gupdate.gcd? I want to use boot.bin from it.
Also I've just found that gupdate.gcd from HondaGW2006-2008-HWID265-EU-RELEASE.rar was not built exactly as I wanted.
It could cause infinite update reboots, as fw_all.bin's version in gupdate.gcd was not equal to the real fw_all.bin's version (2.60).
Instead it was equal to boot.bin's version (4.60). This is due to my GCD utility's nature. I removed the file and I will reupload it when it's fixed.
