What the name of device?

rkDumper 1.09d test

Note that the latest versions of devices give fake data instead of firmware after a certain address.

I think you are right. I dumped using rkdeveloptool and a lot of the partitions were just filled with hex CC.
Probably no solution then.

Your program I had an issue with any command.

Hey buddy, from what i can tell, you are the most talented rockchip developer around.
I have a 7 inch rockchip device that i would love to be able to "unlock" the bootloader. I have full root access to the device (ANDROID 4.2.2) . i can pull and flash the stock images (mtdblock) with dd. but if i modify the boot.img at all it will not boot. (I tested by flashing to recovery) . I have bricked several of these trying to figure this thing out. It definitely is not normal rk firmware. I have several of these particular tablets that i would like to be able to upgrade to Android 5.1.1. i can pay you for the job and i can send you a device

Alas, I'm not a developer at all. It's just a small Uility

you are a developer my friend.... and i need you. Please take a look at my boot.img? this was pulled from mtdblock2 with dd. if you can help me recreate the signature block at 00000400 i would be willing to pay you substantially. Hell id pay you just to try. please take a look bro and let me know if you need to see anything else
