[Sony Xperia E3] Blake Blader:
Hi guys,

I'm flashing a D2203_18.5.C.0.25_ES. ftf firmware via Flashtool version 0.925.0 (old version since the latest one cant detect the any firmware even synced). Now, I've been stuck in Processing of amss_fs_2.sin finished as seen in the log below:

Its taking quite a while now in "Processing of amss_fs_2.sin finished." probably 15mins+ and no more log progress. I've seen "ERROR - root : this bundle is not valid". Where could I have gone wrong? Any solutions Thank you.
