what exactly do u want to know? have u any backup on MOD or not or in WS0 or WS1.there must not be any problem to make the system running on correct pack instead of faulty one.
tell me what do u want to know dir structure or patching on files in SCMANA or the patch conversion details,come up in detail so i can provide u correct info. but these are very critical things do not try on live network.
