I have problem with my htc pico, it stucks at boot.I have cwm recovery v18.104.22.168 and when i try to wipe data/factory i have an error with sd-ext (E:/format_volume make_extf4fs faild to /dev/block/mmcblk0p2). and i have an error when i try to nount sd-ext. i think boot stucks because of this. Can you help please!!
