I have tried your firmware extractor KNOB but it does not do anything. Maybe the manufacturer disabled that feature or maybe my MP4 is not really RK27xx. But I'm pretty sure it's Rockchip because it's what it says when I "safely remove the hardware".
Well, Thank you for your help.. I appreciate it. Good work on that extractor and editor even though I have not tried it.
I've asked a copy of the firmware of my MP4 from the manufacturer but they did not reply to my email. Are they obliged to give me a copy of the firmware? They just sell their stuff but they do not provide any firmware or post any firmware update in their website. They just want our money.
