Cruz Reader Howto: Upgrade the internal microSD memory.

First, we need to open the device, start left and right of where the SD/MMC slot is, use your fingernail (if stable enough) or a flat plastic tool, in order to start popping the back off:

Second, work your way all around the back, carefully lifting the part close to where you already haveopened it a little. You will hear are little popping noise, be careful not to go to fast, or you might break off one or more of the little plastic hooks on the inner side of the back cover.

Third, once you worked your way all around and you have increased the space between back and front frame carefully, listening for the popping sounds, you can take off the back.

Fourth, locate the small opening where the micro SD card sits. The card is held by a metal clamp that locks by sliding to one side, and opens by sliding it to the other side. Slide the metal clamp open, remove the 4GB card, and put the new faster, bigger card in (shown here with an old, slower, but larger 8GB class 2 card, buy 16GB or 8GB, but class 6...)

 
And here is the new card:

Finally, if someone is interested in the wifi card, this shows what is written on the sticker:

Replace the back, essentially by doing the reverse, push the back carefully on to the frame, it will pop again, work your way carefully around...

Good Luck!

What do you use your tablets for? Not for Blogging...

Hi again,

Highly recommended: Install Android System Info (authored by electricsheep) from Market.

This will give you a lot of information on what is going on inside of your cruz reader / android device in general. It also displays the androidID under the OS menu entry on the second tab.

Also, do not use your tablet for blogging, it does take forever to load the edit applet, and you cannot edit anything other than the Title line.... Editing the main blog entry window is not possible on my zt-180.

Highly recommended: Install barnacle wifi tether. It is available on the Market in some countries. I could not get this to show on my US based phone. Had to copy from another device and ./adb install it.

The FixCruxReader-0.04 hack described in this SlateDroid post finally gets some feedback of successful Market, Maps, Gmail installs on the Cruz Reader.

Now, with two tablets and a phone we have a bit of variance in terms of Android OS versions (1.6, 2.0, 2.1) it is time to get the Eclipse based development started, which is a bit of a problem since I am a programming fossil and am used to bare-bones development in assembler and Ansi C. Having some Borland GUI builder development under the belt I found the Eclipse environment (while certainly more capable) somewhat more messy. Eclipse/Android SDK will certainly give me some trouble.
