@ Seamonkey - many thanks for all your help. I tried to do begin the process to do the flash with all three files but upon downloading Setool it consumed the majority of my useage and promptly got moved to quarantine by my antivirus. Research tells me that this is a false positive but nonetheless I was unable to decide which filesystem to download and didn't have enough useage left for both.

Consequently I decided to give Wotan one last go as I had the 2 credits sitting there. I picked all the necessary options from the dropdown and it went through the entire flash procedure before getting to what appeared to be the end when Wotan crashed. Anyhow the phone seems to be back up and running and I have been able to make and receive calls, send items over bluetooth, etc.

Very grateful for all the help and support.

BA
