WM 5.0 reinstallation - memory formating

[chuckchuck]

On my O2 Atom my WM 5.0 installation is corrupted. When I reinstall the latest ROM on that unit the behavior stays corrupted.
On a second unit I have installed the same ROM and everything is working fine.
The problem that I have is that all applications I install give me a message that the author is not know or that these are not PPC applications but only after the first soft reset.
Questions:
Is there a way to ensure that the memory that holds WM 5.0 in the device is working correctly :?: Is there a way to format this memory :?: Does a reinstall of the latest ROM really erase all of the old ROM bits and pieces :?:

thanks for your help, I am aware that the atom is not and xda but I am also aware the you guys are the most profesional community out there.

chuckchuck: on the Universal and Wizard, we have a tool built in called ClearStorage, that is the equivalent of a hardreset, wiping out all memory. Does the atom have a similar app?

vijay555 I have not found such a file on the atom or function on the atom. Would there be a software tool out there that could do it ?
I am a bit puzzled, I always thought that after a ROM install all the old stuff is out the window. This might still be the case but then I guess it would be the memory that is bad.

Try hard resetting the Atom.

With the Atom off, use the stylus to press the reset key at the bottom while at the same time pressing the power-on button.

You will be prompted if you want to do a hard reset (warning - this clears all you device data so make sure you backup what you want first)

press both the "call" and "hangup" buttons and a hard reset will be done.
If you do nothing, after a short while it times out and a normal reset is done.

Thanks for the info, I have done that already, but what I was wondering is whether it is possible after such a hardreset that there will still be code left overs in the memory that could prevent a true clean install.
