AFAIK yes; the brother of the expert works at HP but only M$ stores the ROM images so he has no access to them at all.
Hint for anyone who wants to help me: Copy the files out from your desktop PC-on the handheld GWES or another process locks the files for reading for all processes except ASync.

Seems to be there is no expert at all
1
) MS has nothing to do with it. The ROM had been built by HP
(with Platform Builder from MS
).
2
) ROM files are copy protected. You will have no access at all except running an application.
It would be possible to overwrite ROM with newer files in RAM.
You would have to substitute a lot of files. Since your handheld has only 16 MB RAM there will be not much space left ...
a better way would be just buying a new handheld.

Actually you're both wrong.
Platform Releases do not come from the commercial Platform Builder like Windows CE Core, they come from a a modified platform distribution manager program
(essentially a PB rewrite
). All the image configuration for Platform Releases are locked down, the OEM's can only customise the driver and peripheral application layer to meet their hardware specification.
You CANNOT drag drop a new OS into RAM. It doesn't work like that. You NEED to have the boot block for the relevant version of CE, you NEED to have the system loader for the applicable version of CE. These CANNOT be drag dropped.
You also need drivers, and these are never off the shelf.
All ROM protected files on CE have a header flag - similar to the Indexing service / Read-only / system / hidden header flag in any file on a Windows PC. If this flag is present then when the H/PC runs a system call hooking or something similar over the event it fails the request.
Remembering that they are compressed, write a way to block the call to the file system driver, and you should be able to lift the ROM files directly on the device.
I remind you all that such comments are only speculative, and any actual attempt to lift ROM files is highly illegal and in breach of the H/PC ELUA. :whistles:
@all who want the hack: Open "Mobile Device" in your "My Computer" on the Desktop, navigate to "/Windows" and copy the files.
@C:Amie:Yeah, I forgot the bootblock...And who cares about EULAs???;-
)
Oh before I forgot: How do the Linuxes install their bootloader?

PS: Is the ROM module of the 620lx a modded IDE or what?
