Upgrading the Cisco IOS on Cisco router 3640. benchmark 07-27-07

I will need to upgrade the Cisco IOS on the above-mentioned Cisco
router 3640 so that I can use it as a VPN gateway for a project. I
already obtained the instructions involved from Cisco's website site.
However, when I change the configuration register from 0x2102 to
0x2101 and reboot the router, the router does not go into RxBoot Mode.
ie.router(boot)>.
I have a Cisco router 2503 at home which uses the same Cisco IOS
upgrade instructions as the Cisco router 3620 and when it is put into
RxBoot mode, it displays this prompt i.e.router(boot)> were 'router'
is the name of the router after changing the configuration register to
0x2101 and rebooting the router. The Cisco instructions also states
that you cannot upgrade the Cisco IOS on the router in priviledged
mode i.e.router#.
Any answers will be greatly appreciated.

Thanks,
Benchmark.
