Hoping for some help...
I did the OTA 4.06.651.4 recently and wiped my rom from recovery. Using an old RUU to revert to 3.04.651.2 won't work unless I am S-off, which I have had no luck doing using various methods (rumrunner, revone), I suspect this is because I have hboot 1.56.
I can't get my internal storage to USB PC mount using TWRP 188.8.131.52 -184.108.40.206, otherwise I would flash a custom rom, or use crushalot's guru recovery.
My unit is unlocked, s-on, hboot 1.56, TWRP 220.127.116.11, most recent firmware, no rom.
Any recovery suggestions would be welcome as I am at the end of my rope!!
