I just find it unlikely.
Better yet, impossible.
The reboot into the recovery partition formats /system, then flashes the new /system and baseband. Nothing can be installed from /system.
It would have to be /data (unlikely), /cache (very possible), or /sdcard.
It's 2AM *LOL* I'm half asleep........ I completely missed that very obvious fact.....
Its all good. Only 11pm here and I am studying for an exam.
