ok, thankfully got the problem sorted out.

waited overnight then connected to xss++
reflashed main+fs.

in the process removed patches while flashing
now got the phone working again.

8th time I have tried to patch this phone unsuccesfuly
apparently its not possible to patch z550i.


anyway thanks guys for all your help.
p.s :would like to know if their is any other way to patch this phone.
