Okay, thanks to Mohammad and Meamo.org, I think I'm finally beginning to learn a bit about maemo / linux -Famous Last Words

Anyway, could'nt purge Sygic, but after a process of elimination purged it with
Re-installed Sygic but still shuts down, so learning but not there yet

I think the statement that has been stumping me was this
When flashing the eMMC content, always flash the eMMC image first, then the FIASCO image. Do NOT boot up the device between the two!
So I've been looking for two files to install, and then the firmware.
Now I'm thinking that the FIASCO image is actually the firmware ?
If I'm right I think I need to hook up the phone in usb mode and then in x term use the following:-
Then after complete, and phone still in usb mode due to not ending the command with -R and again in x term use:-
If I'm right the phone should now reboot with:-
(1) Global firmware installed
(2) eMMC completely wiped
(3) Only data remaining on the phone will be on my Micro SDHC card

So in essence a completely reformatted phone in essence the same as a hard factory reset (*#7370#) on Symbian phones.

Phew !, If i'm right can someone confirm (and I'll run thru it), equally if i'm wrong can someone correct me (and if thats the case, I'll come back to it tomorrow ).

As always - any help/comments greatly appreciated
