Unlock the Xoom MZ601 Bootloader with Linux

Why should you want to unlock the bootloader? To flash new custom images. Install the Andorid SDK, then change in the `platform-tools` folder, connect the usb cable and reboot your xoom to the bootloader: cd android-sdk-linux/platform-tools/ ./adb reboot bootloader wait for the device to go into fastboot mode, then run following command: sudo ./fastboot oem unlock follow screen instructions. Note: If you don't run fastboot with sudo, your terminal will just say `< waiting for device >` and nothing happens. In Windows you have to install some drivers, on Linux you can just run the command as root or use sudo. Reference: http://forum.xda-developers.com/showthread.php?t=875630

Notes on first flashing steps with Xoom MZ601

This are my notes on flashing my Motorola Xoom with a Team Eos ICS Android 4.0 Rom.

Prerequisites:

First of all determine the Version of your Xoom: Connect it to your usb port and search in the dmesg messages:

thomas@thinky ~ % dmesg | tail | grep MZ [ 1304.553362] usb 2-2: Product: MZ601

The thread for the Team Eos Rom on xda-developers.com is there: http://forum.xda-developers.com/showthread.php?t=1484770 in the thread there are download links. For MZ601 use the appropriate .zip file.

Check the md5sum.

Copy the zip file on a usb thumb drive not bigger than 8GB.

Power off your Xoom.

Power on and immediately press Power down. Press power down until Android Recovery appears. Press Volume Up to confirm.

At the next screen (green android) press volume up and power. The blue menu appears.

Do Factory reset and wipe cache.

apply update from USB drive, and select your .zip file.

Verifying update package... E:failed to verify whole-file signature E:signature verification failed Installation aborted.

looks like it is not accepting the zip file.

You have to reboot now and unlock your bootloader...

Using a custom Windows 7 iso for the Windows USB tool

I had to install Windows 7 Home Premium on a Laptop where the DVD drive doesn't work. I ordered DVDs, and realized it doesn't boot.

After creating a .iso image of the DVD I realized the Windows USB tool isn't accepting custom .iso images, just the ordered from the windows shop.

To make the Windows tool accepting your .iso file you can use the tool from withinwindows: http://www.withinwindows.com/2009/11/01/use-the-windows-7-usbdvd-download-tool-with-custom-isos/

After using it the Windows USB tool is accepting my image.

Delete NEF/RAW photos where no JPG exists

Sometimes I shoot my pictures with Nikons NEF/RAW format but keep also shooting JPEGs. To sort bad pictures out I only view the JPG and delete them if I don`t like them. After this process I end up with sometimes very much NEF/RAW images which I don`t want. To delete the unwanted NEF/RAW files you could probably just find them in the file explorer and delete them. If you are at a Linux Box, there are better ways to do this. If also using the zsh, you can use this simple command to print all NEF files where no JPG exist: print *.NEF(e_'[[ ! -e $REPLY:r.JPG ]]'_) or just delete them: rm *.NEF(e_'[[ ! -e $REPLY:r.JPG ]]'_) Command based on http://grml.org/zsh/zsh-lovers.html # Show me all the .c files for which there doesn't exist a .o file. $ print *.c(e_'[[ ! -e $REPLY:r.o ]]'_)
