What a weird title for this. He doesn't even say that that actually happened, just that you can override your firmware to make the delete button not work.
Why not create a SD card that doesn't actually delete data (until it gets completely full and there's no other way, of course) but instead encrypts it in such a way that only those who know can retrieve it; sort of like an NSA backdoor, but one you control...
I want to get two PQI Air Cards with WiFi and make a custom firmware to auto-sync the contents. Then there would be a continuous backup to a safe location (e.g. iPod + iFlash) with no additional software needed.
It's not the article title (the real title is "Road to North Korea Photography") but the clickbait, and it's even not true. The author never claims he changed his firmware.
Dear mods e.g. dang, can you pretty please correct this? Thanks.
