So...after a delay, received a 32 gbyte PNY basic micro sd card, unplugged the box , installed the new
sd card and plugged the box back in to power up and reboot...no good! Box locked with no response from remote control... Hmmm!
Read elsewhere in support threads to do a so-called "slow" format with FAT 32 support of the new card...
still no good. Read elsewhere to NOT UNPLUG/DON'T CUT THE POWER to the box when inserting the new sd card...did that, success!! So the takeaway is to avoid a mega sd card, use a 16 gb, perhaps 32 gb max AND remember to install it with the box powered up (very counterintuitive from what we know about electronic hardware, we are almost always advised to turn OFF the power for such a thing as an sd card install). Hope this field report helps...thumbs down to ROKU for NO MENTION of these install requirements anywhere in owners manual.
