Hacking a vReader? Reward offered =)

post #1 of 10
Thread Starter 
Edit: not trolling, my name is based on my Reddit name tongue.gif

So I got one of these for my kid, and the content available from vTech is limited... VReader-Menu-Screen.jpg

I want to root it & put Linux on it biggrin.gif

Based on searching so far, I can not find any such projects except there is a ROM for a different touch-screen vTech product out there.

Now I know this may be difficult, so for incentive I am offering up a free Steam game to anyone that goes "above and beyond" to assist.

Specs are hard to find, so I don't know what runs it (props to anyone that can find out for me!) Here's what I know:

> Has a touchscreen (capacitive)

> Screen size: 4.3 inches

> Takes an SD Card, USB mountable.

Edit: Found specs. Samsung S3C2440 processor (ARM 9 architecture), 64MB RAM, expandable storage via SD card (takes at least 4GB, dunno SDHC)

ARM920T core; 16/32-bit RISC microprocessor with separate 16 KB instruction and 16 KB data cache, MMU to handle virtual memory management, TFT& STN LCD controller, NAND flash boot loader, system manager (chip select logic and SDRAM controller), 3-ch UART, 4-ch DMA, 4-ch timers with PWM, I/O ports, RTC, 8-ch 10-bit ADC and touch screen interface, camera interface, AC97 audiocodec interface, IIC-BUS interface, IIS-BUS interface, USB host, USB device, SD host & multimedia card interface, 2-ch SPI and PLL for clock generation.

I don't know; searched for HOURS (literally) and couldn't find specs frown.gif

Can you open it up and take pictures of the PCBs?

anything is hackable as long as hackers have a need for it.

So I'm guessing it can use the same arm gcc toolchain that Android uses?

Android-ndk.

Gotta figure out how to root it first, looking for any assistance biggrin.gif

Unless there is someone who has already rooted this device and posted instructions somewhere on the internet, it is probably not feasible for you to root it yourself.

Rooting a device requires a solid understanding of exploits, OSs, programming, security, etc... You're going to have to find a security flaw to exploit and potentially you may have to use a self-written rootkit.

First off, if the kernel is Linux than I should be able to request a copy of the source, right?

Second off, there isn't someone who has rooted / posted instructions online, until someone cracks it and posts online ^_^

Finally, one could postulate that I have working knowledge of the above info & security shouldn't be a HUGE issue (it's a kid's toy, not a iPad or something... can't imagine too much R&D went into it. I am more here to figure out the community interest in such a hack, along with any recommendations of what could run on that hardware with little issue. As for accessing the file system, I can do that but until I get to console as root (which is what I am stuck at now) I can't do much of anything else (eg, replace the bootloader).
