Specially orders reads to flash RADIO has the help:

The HP IPAQ 6515 uses the boot loader2 password to unlock the full help menu in the serial console interface. It does not allow access to more commands than before and simply shows help for more commands.

If you are interested in viewing the commands there are a couple of passwords that would unlock it depending on your exact 6515 model.

•	BOOTLOADER

•	BEETLES

•	0000000000000000 - (16 x 0s) password for level 1 which unlocks additional RUU functions

Personally, both BOOTLOADER and 0000000000000000 worked fine for me on a HP IPAQ 6515e and you can enter level 1 directly with 0000000000000000

USB>password BOOTLOADER

HTCSPass.<Y-HTCEUSB>password 0000000000000000

If you typed the wrong password, you will get

USB>password 0000000000000000

HTCSInvalid password

Similarly passes on 6915 !

This is a use MTTY Connection of me exploring the IPAQ 6515e’s bootloader firmware
