Try the full wipes then pull you're battery out replace then try flashing the rom as I had similar problems to what you're reporting on my g300 and I still sometimes have to pull the battery when backups decide to not restore. Worth a try.
Unfortunately no luck with this trick
EDIT: I think I found the problem: my first Blade was an Orange San Francisco (aka ZTE Blade 1 SIM locked), but after installing CyanogenMod the SIM lock disappeared.
I thought that even with the new Blade III (Orange ZTE 3: http://shop.orange.c...i/invt/10061153
) installing a new ROM could unlock the phone, but when inserting a SIM different from Orange with Aurora Borealis I'm asked to insert a Network Unlock code, so the SIM lock is still there. Maybe CM10 crashes for that reason...
