Root a cruz r101 - Velocity Micro Cruz Reader R101 Tablet PC

SOURCE: Just bought a cruz reader

Before you can communicate with your computer you must run CruzSync from the desktop. There are some driver files that must be sent from cruz to point the way to the reader. After you do this it should connect every time. Some time you will have to pull the USB out and put it back end, especially if the reader or the computer has just woke up from a sleep or hibernation mode. ZumoDrive is the account you must set up when you click or press on CruzSync to make all of this happen. Hope this helps

SOURCE: How do you restor you

The easiest way to restore the Cruz Reader to factory defaults is to update to the newest firmware which can be downloaded from here. The instructions for doing the upgrade are also explained on the link above.

This will revert everything back to original condition leaving any information on the internal and external memory cards intact. If you are looking to clear those as well you can do so by formatting the cards by going to Settings->Storage (might say SD card)->Unmount->Format. You can also take the cards out and put them in your computer and use the computer to format them.

The process is pretty of upgrading the firmware is pretty simple even though it might be intimidating. Let me know if you have any more questions

Hope this helps

This sounds similar to something that happened when I tried rooting my android phone. If it's the same thing, that means you will need to go to recovery mode and install an update.zip package that you can find somewhere online for it. It's because the code for what's supposed to happen after that screen is overwritten and it doesn't know where to go.

Yes. Flashing the ROM does the same thing as updating your firmware. You are simply updating your firmware to one that isn't the original. All you do is load up the file from the velocity website onto your SD card and flash and you will be back at the standard ROM.
I suggest Macho ROM or JGM if you want the android market. Both run overclocked if you so choose which is much faster. JGM also has a vanilla rom (and there is and improved vanilla rom) which gives the tablet bare-bones applications if you want it to be just a reader. I would follow the method for flashing jgm. It lays out how to set up app2sd and all that.
4shared.com allows you to download apps that are not found in the market or whatever after you have rooted. Simply search the name of the app and put .apk at the end. Be careful as you can get malware from this. This method breaks copyright laws as all apps on it are offered for free and I only suggest it to download apps that are free on the market...
